Users with hearing impairments may benefit from the use of the following ATs:

Users with mobility impairments may benefit from the use of the following ATs:

Users with cognitive disabilities may benefit from the use of the following ATs:

Some of these assistive technologies can be designed into the product lines themselves; others must be used externally to the device. There is an ongoing debate regarding the role of AT in universal design. At the core of the issue is whether the capabilities of AT should be built into mainstream products (those designed for the general public) or whether they should be separate products that can be used with mainstream products by those who need them. There are three schools of thought regarding the use of AT:

1. AT should be the primary solution to providing people with disabilities access to E&IT.

2. E&IT manufacturers should enhance the accessibility of their products to extents that are technically possible and economically feasible. Beyond this, AT should be used.

3. E&IT manufacturers should make all their products accessible by everyone, under all circumstances, in any situation.

While it is clear that a single design cannot accommodate all individuals in all contexts (Stephanidis, 2001; Vanderheiden, 1990), an inclusive design can accommodate a larger number of people than one designed for the “average” user. In addition, ATs themselves cannot readily accommodate the needs of all users, and it is burdensome and costly for AT to keep up with changing mainstream technologies. On the other hand, AT developers have detailed knowledge about the needs of users with various functional limitations, and they can develop better products if they can focus on the needs of their target users.

Some believe that the solution is for AT developers to develop better products rather than mainstream developers trying to design products that are useful to everyone. However, with this approach, people who need assistive technology are required to purchase AT products in addition to the mainstream products. They must also carry their AT device around so that they always have the capability to use a product. The best solution is, perhaps, a middle ground, keeping in mind that part of UD is ensuring compatibility with some types of AT (e.g., touchsticks), but UD doesn’t have to require the use of AT.

…[U]niversal design in [information technology and telecommunications] IT&T products should not be conceived as an effort to advance a single solution for everybody, but as a user-centered approach to providing products that can automatically address the possible range of human abilities, skills, requirements, and preferences (Stephanidis, 2001).

Assistive technology development, whether or not it is integrated in mainstream products, is critical. The Assistive Technology Act of 1998 (P.L. 105-394) provides federal support for research and promotion of AT; Title II specifically relates to coordinating research for assistive technology and universal design (U.S. Department of Commerce, 2003).

There are a number of arguments against the design of AT as separate products:

• AT requires added cost on top of the mainstream products and is affected, in part, by insurance reimbursement policies (U.S. Department of Commerce, 2003).

• AT is sometimes prohibitively expensive, even without the cost of the mainstream products.

• It is not always possible for a person to carry around all necessary AT products.

• AT is focused on a limited audience.

• Different AT is needed to accommodate different functional limitations.

• The economics of ATs are such that the limited market and limited purchasing power of the market will likely limit the abilities of AT companies to keep up with the pace of mainstream technologies.

• Often when an innovation in mainstream technology takes place, an update in the AT is required; this results in extra cost for the person requiring AT or, at the very least, introduces risk. For example, installation of a new software product may interfere with the operation of existing AT. Technology is changing so rapidly that once an access problem is solved, it is common for a new access problem to surface (Stephanidis, 2001; Emiliani, 2001).

• While ATs can be portable, security concerns may prohibit their use; for example, a library may prohibit the installation of a screen magnifier on a public computer.

• AT companies do not have the resources needed to work closely with companies to ensure compatibilities with their products or to do product testing (U.S. Department of Commerce, 2003).

• AT companies often do not share the features they have planned for their products with other companies until the AT is released. While industry would like to have the data sooner, AT companies are reluctant to promise technologies that they might not be able to deliver.

Arguments favoring the design of ATs as separate products include the following:

• AT allows companies to focus on the development of their specialized products, thus resulting in a better job of handling the accessibility issues to meet the needs of people with disabilities.

• It is possible for AT to become so mainstream that it is no longer considered AT. Eyeglasses, for example, are no longer thought of as assistive technology, and closed-captioning and voice recognition software are becoming more commonplace.

• AT is better equipped to handle specialized or rare needs of people with disabilities, and there will likely always be a need for some forms of assistive technology. In addition, AT can be tailored to address unique needs (U.S. Department of Commerce, 2003).

Arguments for integrated AT and UD include the following (Vanderheiden, 1990; Winograd, 1997):

• Many product adaptations necessary to accommodate some functional limitations can be implemented in mainstream products at little or no extra cost.

• Many product adaptations necessary to accommodate some functional limitations can also facilitate use by the general population (e.g., the curb cut). Some benefits of implementing accessibility features that have a more global benefit include lower fatigue, increased speed, and lower error rates.

• AT cannot accommodate the needs of the many individual subgroups that have special needs (e.g., mild versus severe hearing loss).

• Special features can be integrated into mainstream products so they are transparent to users who don’t need them (e.g., “sticky keys”).

Regardless of how people with disabilities use the technology, it will have a large impact on their independence and ability to fully participate in society, resulting in an added cost benefit to society as a whole (Vanderheiden, 1990). The population of people who may require some sort of accommodation is ever-growing with the increase of the elderly population, so much so that the term “general population” possibly should be redefined in the minds of designers. Although the market potential for products is great, the limited population for any given AT creates financial constraints for small companies that focus on AT development. Large companies typically have the finances but not the expertise to address a wide range of needs (AAATE, 2003). Complications stem not only from the wide variety of functional limitations but also from the ever-increasing need for rapid configuration of technologies to accommodate environmental and other contextual needs. The increasingly mobile society, for example, may mean that individuals need specialized accommodation over a period of a day or even hours, while a more fixed environment may require little variation in configuration. “…[I]n the context of the emerging distributed and communication-intensive information society, users are not only the computer-literate, skilled, and able-bodied workers driven by performance-oriented motives, nor do users constitute a homogeneous mass of information-seeking actors with standard abilities, similar interests, and common preferences with regard to information access and use” (Stephanidis, 2001, p. 6). The AT industry alone cannot address the variable contexts that create a need for more customized situational technologies.

If products are not going to be designed with AT built in, they need to be designed from the ground up to be fully compatible with AT, and AT needs to be designed so well that people with disabilities no longer have accessibility issues with products. If products are designed with UD principles in mind, they will likely be accessible to a large number of people with disabilities without the use of AT. Regardless of the resolution to this debate, if any, AT and mainstream developers must work together to achieve the greatest accommodation possible and to develop adaptors, when necessary. “The use of an adaptor is appropriate when two systems cannot otherwise accommodate each other; this is the case when accessibility problems are alleviated by the choice of alternative input/output devices or by communication via an alternative modality” (Benyon, Crerar, and Wilkinson, 2001). Thus, there is a place in society for both integrated AT and UD, as well as for separate AT products.

Research Process

An extensive research program was conducted to complete each of the research activities documented in this report. This research program was conducted by examining the roles and perspectives of industry, Federal Government, and consumers with respect to the six product lines that are important to people with disabilities. The six product lines studied were automated teller machines (ATMs), cellular phones, distance learning software, personal digital assistants (PDAs), televisions, and voice recognition technologies.

II. Market Definition and Research

Electronic and information technology is driving the creation of new communities that are forever changing the way people live, learn, work, and play. Companies are increasingly expanding their presence in emerging markets. Businesses are serving populations they have never served before. Every consumer is different. No two people have the same set of characteristics, learning styles, abilities, experiences, or educational backgrounds. Developing products that accommodate the wants, needs, and preferences of as many individual consumers as is technically possible and economically feasible can greatly enhance a company’s competitive advantage.

Designing with access in mind can significantly increase the size of E&IT markets on a global basis. Good business practices dictate that designers and engineers avoid excluding large groups of consumers from accessing and using E&IT. Groups at the highest risk of unintentional exclusion are—

• People with disabilities

• Individuals 65+ years old

• Consumers living within low-bandwidth information infrastructures

• Users of English as a Second Language (ESL)

• Tourists traveling to nonnative language destinations

• Consumers living in high-density populations

This market analysis examined many aspects of manufacturing “more accessibly designed” E&IT. This analysis was intended to help answer questions such as the following:

• Is there a market for more accessibly designed products?

• Does the capacity exist to develop more accessibly designed products in each of the presented product lines?

• What factors influence the market for more accessibly designed products for each of the product lines presented?

All the product lines reviewed in this report are manufactured by members of the E&IT industry. Naturally, in order for these products to be manufactured, the E&IT industry must exist. In order to exist, it must be profitable. A question often asked by the disability community is, “How can we ensure that the E&IT products and services being manufactured are accessible to people with disabilities?” E&IT manufacturers pose a similar question. They ask, “How can we ensure that the E&IT products and services we manufacture are accessible and usable by as many people as is technically possible and economically feasible without the need for customization?” The questions are different. The motivations are different. The market drivers are different. The solutions can be remarkably similar.

Definition of the Market Environment

Historically, the primary forces driving the manufacture of more accessible E&IT products and services have been legal, moral, social, and ethical. The assumption was that if legal, moral, social, and ethical issues no longer existed, the motivation to manufacture more accessible E&IT would all but disappear. The next two sections discuss the reasons why nothing could be further from the truth.

In contrast to the historical notion of what the primary forces driving the manufacture of accessible E&IT are, in actuality a majority of the forces driving demand for more accessibly designed E&IT fall into the following five categories:

• Market forces

• Local environment

• Human condition

• Legal framework

• Standards and guidelines

Market Forces

Market forces consistently drive the demand for more accessibly designed E&IT. Market forces include the need to respond to consumer behavior, the work of federal agencies, legislation mandating developments in the accessibility of E&IT, changing marketing philosophies (from mass marketing to a one-on-one marketing philosophy), competition within the market, emerging technology trends, and economic expansion. These market forces are discussed below in terms of how they drive the markets for more accessibly designed E&IT products.

Consumer Behavior

E&IT is prevalent in schools, libraries, individuals’ homes, work environments, places of recreation, banks, and even supermarkets. It is because of this widespread presence that consumers are more technically literate than they were five years ago. Devices such as cell phones, PDAs, voice recognition systems, and the wireless Web enable us to carry our offices with us when we travel. We are more mobile now than ever before. Consumers have become accustomed to getting the information they need when they need it and where they want it. This has created an expectation of immediacy. When consumers don’t get what they want quickly, they become impatient. E&IT designers need to respond to consumer behavior by providing products and services that not only meet but exceed the high expectations of a technically literate, mobile consumer base. Increasing the accessibility of information services and mobile technologies increases access to the information demanded by consumers with high expectations.

Federal Government

The Federal Government serves as a catalyst for more accessibly designed E&IT products through its buying power, the development of legislation, and the support of AT accommodation labs. Section 508 of the Rehabilitation Act amendments of 1998 mandates the purchase of accessibly designed E&IT. As a result, all federal agencies appointed section 508 coordinators (Section 508, 2003). Those coordinators are responsible for organizing and supporting the implementation of section 508 in their respective departments and agencies, and they serve as the central point of contact for information concerning accessibility issues and solutions. In addition to section 508, other legislation provides guidelines for designing more accessible E&IT. The Architectural and Transportation Barriers Compliance Board (Access Board) developed the ADA Accessibility Guidelines for Buildings and Facilities (ADAAG), and the Telecommunications Act Accessibility Guidelines (section 255) mandates the design of more accessible E&IT products and services. There are also presidential initiatives driving the design of more accessible E&IT. These initiatives include the President’s New Freedom Initiative (White House, 2001), the No Child Left Behind Initiative (U.S. House of Representatives, 2002), and the disabilityinfo.gov Web site (DisabilityInfo.gov, 2003).

In addition to these acts and initiatives, many federal agencies have created AT accommodation labs. These labs serve as focal points for information regarding accommodations, disabilities, and assistive technology. These resources include the following:

• Department of Agriculture’s TARGET Center
  http://www.usda.gov/oo/target

• Department of Education’s Assistive Technology Program
  http://www.ed.gov/offices/OCIO/programs_services/assistive_technology/index.html

• Department of the Interior’s Accessible Technology Program
  http://www.doi.gov/atc

• Department of Transportation’s Disability Resource Center
  http://www.drc.dot.gov

• Department of Labor’s Job Accommodation Network
  http://www.jan.wvu.edu

• The National Institute on Disability and Rehabilitation Research, U.S. Department of Education’s ABLEDATA database of assistive technologies
  http://www.abledata.com

• Department of Veterans’ Affairs Adaptive Training Program
  http://www.va.gov/oirm/itss/itc/brochsb.htm

• General Services Administration’s Center for Information Technology Accommodations (CITA)
  http://www.gsa.gov/Portal/gsa/ep/contentView.do?contentId=9815&contentType=GSA_OVERVIEW

Clearly, the Federal Government is an important market force for driving accessibility requirements.

Marketing Philosophies

Marketing philosophies have changed radically over the past 35 years. The marketing philosophy of the 1960s was mass marketing (Mass Marketing Definition, 2003), in which the seller views the market as a homogeneous whole and, therefore, has only one marketing program (the same product, the same price, the same promotion, and the same distribution system) for everyone in the population. This type of marketing is also referred to as unsegmented or undifferentiated marketing.

Marketing philosophies of the 1970s included product line extension (Product Line Stretching Definition, 2003) and market segmentation (Market Segmentation Definition, 2003). Product line extension adds depth to an existing product line by introducing new products in the same product category. Market segmentation is the division of a totally heterogeneous market into groups or sectors with relatively homogeneous needs and wants.

In the 1980s, the marketing philosophy shifted to one of niche marketing (Niche Marketing Definition, 2003). Niche marketing or concentrated marketing is a marketing segmentation strategy in which the firm focuses all its efforts and resources on serving one segment of the market.

In the 1990s, value-added marketing became popular. Value-added marketing is a strategy in which a company buys products, customizes them for a particular application, and then resells them. There was also a shift toward marketing to individual customers rather than to the larger mass. Don Peppers and Martha Rogers invented the phrase “one-to-one” marketing (Peppers and Rogers, 1997) to illustrate the revolutionary concept of treating different customers differently. One-to-one marketing supports the establishment of permanent relationships with your customers. One-to-one subscribes to providing products and services to customers according to their individual wants, needs, and preferences. “Share of customer” replaces market share. The marketing focus shifts from institutions to individual consumers.

Once a company acquires the knowledge and experience required to manufacture more accessibly designed E&IT, it can take an asset marketing approach (Asset-Based Marketing Definition, 2003) to providing its E&IT products globally. Asset marketing uses the knowledge and skills a company has already developed as the basis for growth. For example, a company that is skilled in developing kiosks that are accessible to people who are blind can market kiosks designed in a similar manner to countries that have high populations of people who have never learned to read. This global marketing (Global Marketing Definition, 2003) philosophy enables companies to sell the same, or very similar, products to world markets with essentially the same promotion. This marketing approach is also commonly referred to as international marketing.

Competition

Competition in the E&IT industry is fierce. The industry is constantly looking for ways to increase efficiency, competitive advantage, sales, market shares, and profitability. It is also looking to cut costs. Businesses are constantly developing new and innovative products and services with the hope of achieving these objectives, and adding functionality that enhances the accessibility and usability of a product can be very beneficial. In extremely competitive markets, several companies have correctly identified UD as a potential market discriminator. When highly similar product lines are all competing for the same customer, a product designed with access in mind may have the needed advantage required to outbid the competitors.

Technology Trends

A variety of rising mainstream technology trends fuels the need for more accessibly designed E&IT. The functionalities of multiple individual devices are now being integrated into a single device, including pagers, cell phones, PDAs, palmtop computers, smart phones, MP3 players, and so on. This trend is creating a dependence on one device to accomplish multiple functions. Thus, if not more accessibly designed, this multiple functionality precludes the use of such devices by certain segments of the population, for example, people 65+ years of age. Developing and manufacturing an accessible interface for a device that provides multiple functions is less expensive than developing and manufacturing an accessible interface for multiple single-function devices.

Decreasing costs are making E&IT devices more affordable to emerging markets, which have the greatest concentration of individuals with low income and a greater concentration of individuals who are unable to read and write. E&IT manufacturers need to move into emerging markets in order to increase sales and gain competitive price advantage through economies of scale.

Increasing processing power, disk storage, memory capacity, and battery life are enabling developers to integrate advanced access technologies (speech recognition, text-to-speech synthesis, projected displays, etc.) into devices where it had not previously been technically possible to do so. In addition, the Internet and the World Wide Web are now being used as a primary infrastructure for education, government services, news, and business. Customers’ technical knowledge and expectations are constantly increasing, along with the use of wireless Internet appliances and wireless infrastructures. Legal mandates to manufacture more accessibly designed E&IT in support of people with disabilities are a driving force behind these technological trends.

Economic Expansion

The strength of our global economy is, to a great extent, the result of the investment in and application of new technologies by governments, businesses, and individuals. Technology is the foundation upon which developing countries can build thriving, financially independent, self-sufficient economies. The technologies that build this foundation include computers, networks, ATMs, wired and wireless information infrastructures, wireless handheld Internet appliances, and cellular telephones, to name a few. Applications include online banking, distance learning, e-government, and e-commerce (World Information Technology, 2003).

Local Environment

Another force that drives the market for accessibly designed E&IT is local environments. The following is a discussion of two environmental factors: variances in bandwidth and tourism.

Bandwidth

As of May 2004, more than half (51.39 percent) of home Internet users in the United States relied on dial-up modems of 56Kbps or less. Of all U.S. home Internet users, 42.53 percent used 56Kbps modems, 6.52 percent used 28/33.3Kbps modems, and 2.34 percent used 14.4Kbps modems (Nielsen/NetRatings, 2004).

Computers using dial-up connections cannot handle graphics as quickly and efficiently as computers connected via broadband. It is for this reason that dial-up users surf the Internet with graphics turned off. They do this to speed up downloads. Low-bandwidth connections do not lend themselves to a lot of graphic images, video-based information, or streaming audio. Multimedia content can be problematic for users with slower connections. Wireless devices communicating with the Internet at slow connect speeds can also be a source of accessibility and usability problems.

There are solutions to these problems. Some companies have the ability to control the settings on the browsers used on their employees’ PCs. When available corporate Intranet bandwidth is at a premium, these companies can simply issue a central command to turn off graphics on all client PC browsers. This can immediately free up as much as 80 percent of available bandwidth. Designing Web sites for low-bandwidth access tends to increase accessibility for users with disabilities. For example, a graphics- or animation-intensive site often requires high bandwidth and is inaccessible to those who are blind. In contrast, a text-based site loads quickly and is accessible to screen readers. Dial-up environments will continue to drive the development of more accessible E&IT in the foreseeable future.

Tourism

During the first quarter of 2004, the United States welcomed 8 million international visitors. This was an increase of 12 percent compared to the first quarter of 2003.

Visiting tourists often make use of ATMs, self-service kiosks, ticketing kiosks, and other tourism-related information technologies. Many tourists use English only as a second language. Content written in simplified English is more understandable to users of ESL. Simplified English content has other significant benefits. For example—

• It reduces the cost of language translation.
• It reduces ambiguity.
• It speeds reading.
• It reduces liability associated with misunderstandings.

The use of simplified content was originally included in various accessibility design guidelines in support of people with cognitive reading disabilities. Using simplified language has now evolved into a market force driving the design of more accessible E&IT.

Human Condition

Aside from forces stemming from the market and the environment, many of the forces driving the accessible design of E&IT fall under aspects of the human condition. E&IT products must be designed with people of different disabilities, various age groups, various levels of literacy, various languages, different learning styles, and different experience levels with activities such as using the Internet in mind. These aspects of the human condition bring with them the demand for accessible E&IT products that cater not just to one category but to many different types of users. Below is a summary of the forces that drive the demand for E&IT that is accessible to a wide range of users.

Disability

Census 2000 counted 54 million people in the United States with some type of long-lasting condition or disability (NCD, 2004). These individuals represented 19.3 percent—nearly one in five people—of the 257.2 million people age five and older in the civilian, noninstitutionalized population. Their conditions included a wide range of disabilities, not all of which precluded the use of E&IT. Within this population, Census 2000 found—

• 9.3 million (3.6 percent) with a sensory disability involving sight or hearing
• 21.2 million (8.2 percent) with a condition limiting basic physical activities, such as walking, climbing stairs, reaching, lifting, or carrying
• 12.4 million (4.8 percent) with a physical, mental, or emotional condition causing difficulty in learning, remembering, or concentrating
• 6.8 million (2.6 percent) with a physical, mental, or emotional condition causing difficulty in dressing, bathing, or getting around inside the home
• 18.2 million of those age 16 and older with a condition that made it difficult to go outside the home to shop or visit a doctor (8.6 percent of the 212.0 million people this age)
• 21.3 million of those ages 16 to 64 with a condition that affected their ability to work at a job or business (11.9 percent of the 178.7 million people in this age group)

E&IT products and services that are accessible to people with disabilities appeal to the wider population as well. Accessible design can significantly enhance the sales of a product. For example, all of the following products were first developed in support of people with disabilities and are now used by the wider population:

• Auto-dialers
• Flatbed scanners
• Microphones
• Speech recognition
• Speech synthesis
• Talking ATMs
• Talking caller ID
• Vibrating pagers

Age

There are 36 million consumers 65 years of age and older living in the United States (Population, 2003). People 65+ years of age are often not able to see, hear, think, or move about as easily as they did when they were younger. In order to enable people 65+ years of age to access and use E&IT, these differences must be accommodated. In addition, 52 percent of people 65+ years of age have some type of disability. Thirty-three percent of persons 65+ years of age have a severe disability.

By 2030, there will be about 70 million older persons, more than twice the number in 2000. People 65+ represented 12.4 percent of the population in the year 2000, but are expected to grow to 20 percent of the population by 2030 (Administration on Aging, 2002). Furthermore, individuals who are accustomed to operating E&IT will demand accessible E&IT as their functional capabilities diminish.

Language

Language is certainly a driving force in today’s market for more accessible E&IT. According to Global Reach, there are 262 million English-speaking people online. Non-English-speaking populations online are 474 million. By the end of 2005, the ratio of English-speaking to non-English-speaking users will decrease significantly (Global Reach, 2003).

Sixty-four percent of people who visit the Internet seek sites in languages other than English (Global Reach, 2003). In a world where International Data Corporation (IDC) predicted that Internet spending outside the United States will have exceeded $914 billion in 2003, effective Web site globalization is the next imperative of Internet enterprises (IDC, 2000). Despite the vast international opportunities projected, few U.S. companies appear poised to take advantage of them. More than half (55 percent) of U.S. companies do nothing to customize their Web sites for foreign visitors; less than one-quarter even allow a choice of language, according to recent IDC Internet Executive ePanel research. With such minor globalization efforts, it is not surprising that 72 percent of U.S. companies that are online currently draw only 10 percent or less of their e-commerce revenue from outside the United States. To increase their e-commerce revenue, companies must strive to design Web sites that are accessible to the non-English-speaking population.

Learning Style

There are three major types of learning styles (Live Text, 2000). They are visual, auditory, and kinesthetic. Visual learners need to see a person’s body language and facial expression to fully understand the content of what is being said. They tend to prefer sitting at the front of a classroom, play, or lecture hall to avoid visual obstructions (e.g., people’s heads). They may think in pictures and learn best from visual displays, including diagrams, illustrated textbooks, overhead transparencies, videos, flipcharts, and handouts. During a lecture or classroom discussion, visual learners often prefer to take detailed notes to absorb the information. Auditory learners learn best through verbal lectures, discussions, talking things through, and listening to what others have to say. Auditory learners interpret the underlying meanings of speech through listening to tone of voice, pitch, speed, and other nuances. Written information may have little meaning until it is heard. These learners often benefit from reading text aloud and using a tape recorder. Tactile/kinesthetic learners learn best through a hands-on approach, actively exploring the physical world around them. They may find it hard to sit still for long periods and may become distracted by their need for activity and exploration. Enabling people to acquire information in the manner most appropriate to their learning style(s) enhances the effectiveness of E&IT and accommodates users with sensory disabilities.

Experience Level

Many people who are learning to use an application on the Web for the first time want all the help they can get. There will come a time, however, when the extra help is no longer needed or desired. One of the benefits of accessible design practices is having the ability to customize user interfaces based on the wants, needs, and preferences of individual users.

Legal Framework

The following is a summary of key laws, statutes, and standards that have improved accessibility for individuals with disabilities in this country. Each law is summarized, followed by a discussion of who is primarily affected by the law and the law’s approach toward addressing accessibility issues. These laws and standards are a driving force in the market for accessibly designed products, as they set the standards and guidelines for what must be done by the government and industry to accommodate the needs of individuals with disabilities.

Section 508 of the Rehabilitation Act

Section 508 of the Rehabilitation Act of 1973 requires that when federal agencies develop, procure, maintain, or use E&IT, they must ensure that individuals with disabilities have access to and use of information that is comparable to the access and use by federal employees who do not have disabilities, unless an undue burden (significant expenses or difficulties) is imposed on the agency. The law also requires that individuals with disabilities in the general public seeking information or services from a federal agency have access to information and services comparable to that provided to individuals without disabilities, unless undue burden is imposed on the agency. When compliance does impose an undue burden, agencies must still provide disabled individuals with the information and data by allowing them to use it by an alternative means of access (e.g., captioning, audio description).

Section 508 covers E&IT such as computer hardware, software, networks, ancillary equipment, firmware, technology services, telecommunications products, information kiosks and transaction machines, World Wide Web sites, multimedia, and office equipment such as copiers and fax machines. Section 508 does not cover equipment that contains embedded information technology that is used as an integral part of the product but the principal function of which is not the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information (e.g., HVAC equipment and medical equipment). As a guideline, E&IT systems can be considered to be accessible to individuals with disabilities if they can be used in a variety of ways that do not depend on a single sense or ability.

Section 508 has the potential to greatly improve accessibility to E&IT for individuals with disabilities. The Federal Government will likely become a better employer to the many people with disabilities who work for it, as well as a model employer for industry. In addition, members of the public with disabilities will have greater accessibility to government information and services related to technology.

Those affected directly by section 508 include federal departments and agencies and vendors that serve the Federal Government. The initial impact is at the procurement stage. Section 508 must be integrated into the procurement process by determining which technical provisions from section 508 apply in a given situation, performing market research to determine the availability of products and services that meet the applicable technical provisions, deciding which technical provisions, if any, do not apply due to an exception, and submitting technical specifications and minimum requirements to a contracting officer.

Private companies and software developers are also affected by section 508. Although section 508 does not require private companies to alter their products, full implementation of the law may provide an incentive for companies that want to do business with the government to build better accessibility features into their products. Currently, however, there is a perception by some in industry that section 508 conformance is being “rubber stamped” by procurement officials and that the content of documents describing section 508 conformance, such as voluntary product accessibility templates (VPATs), is not important as long as it is merely offered. If section 508 is fully addressed by procurement officials, accessibility will become a key discriminator for federal sales. Increased competition will raise the bar for hardware and software vendors that want to create new and innovative solutions to addressing accessibility issues. Software developers are affected by section 508 in that they are now trying to integrate the applicable section 508 provisions into their entire software development life cycle. Developers are faced with the challenge of either making their software compatible with assistive technology or making software products accessible without the aid of other AT.

In contrast to other federal laws that take a “push” approach toward improving the accessibility of E&IT by mandating that new, better technologies are manufactured and adopted, section 508 does not explicitly require manufacturers to make their products more accessible. Rather, section 508 uses a “pull” approach, in which the federal agencies are responsible for seeking better products to address accessibility problems by procuring products that comply with the provisions when such products are available in the commercial marketplace or when such products are developed in response to government solicitation.

Section 255 of the Telecommunications Act

Section 255 of the Telecommunications Act of 1996 requires that telecommunications products and services be accessible to people with disabilities, to the extent that such access is readily achievable. If manufacturers cannot make their products more accessible, they must design products to be compatible with adaptive equipment used by people with disabilities when it is readily achievable to do so.

Telecommunications products covered under this Act include wired and wireless telecommunication devices such as telephones, pagers, and fax machines; products that have a telecommunication service capability such as computers with modems; and equipment that carriers use to provide telecommunications services, which includes the software integral to that equipment. Also covered are basic and special telecommunication services, including regular telephone calls, call waiting, speed dialing, call forwarding, computer-provided directory assistance, call monitoring, caller identification, call tracing, repeat dialing, interactive voice response systems, and voice mail.

The implementation of section 255 of the Telecommunications Act stands to improve access and the number and range of accessible products in the telecommunications industry. Companies that manufacture telecommunications products or provide telecommunications services are expected to shift toward a more universal, inclusive design process in the development of new products and services. Those affected by section 255 include manufacturers of telecommunications equipment and customer premises equipment as well as the providers of telecommunications services. Companies must research ways to make their products more accessible and provide training for their staffs on accessibility. Manufacturers must modify their design processes to ensure that accessibility and usability are considered in the earliest design phases of a product. The law has been beneficial to manufacturers and service providers because they have found that by making products easier to use for people with disabilities, the products often are easier for everyone to use.

Section 255 takes more of a push approach toward improving accessibility by establishing a set of guidelines that manufacturers in this industry must follow in designing new products and services. Companies are advised to use these guidelines and implement training procedures as specified by the law. Section 255 is related to section 508 of the Rehabilitation Act in that the U.S. Access Board has incorporated the language of the guidelines specified in section 255 into the 508 standard. This consistent language has enabled companies to develop products that meet both the design requirements of the manufacturers and the procurement requirements of the federal agencies.

Hearing Aid Compatibility Act

The Hearing Aid Compatibility (HAC) Act of 1988 requires that the Federal Communications Commission ensure that all telephones manufactured or imported for use in the United States after August 1989, as well as all “essential” telephones, are hearing aid compatible. “Essential” telephones have been defined as coin-operated telephones, telephones provided for emergency use, and other telephones frequently needed for use by persons with hearing aids. This includes telephones in the workplace, in confined settings such as hospitals or nursing homes, and in hotel and motel rooms.

Telephone manufacturers are directly affected; they must design phones with volume control and other features for users with hearing aids. Owners of hospitals, hotels, and other places with “essential” telephones must ensure that the telephones they purchase for their buildings are hearing aid compatible. Employers must ensure that all telephones in both common and noncommon areas in their workplaces are hearing aid compatible and that any new telephones they purchase are hearing aid compatible.

Unlike section 255 of the Telecommunications Act, in which companies must ensure that their products are accessible to hearing aid users only if it is readily achievable for them to do so, under the HAC Act this requirement is absolute. Like section 255 of the Telecommunications Act, section 255 takes a push approach, mandating that corporations and business owners purchase telephones that are hearing aid compatible and that the Federal Communications Commission (FCC) ensure that all essential telephones and telephones manufactured or imported for use in the United States are hearing aid compatible.

Americans with Disabilities Act

The Americans with Disabilities Act (ADA) of 1990 recognizes and protects the civil rights of people with disabilities. It provides protection from discrimination against individuals on the basis of disability. Covered under the ADA are a wide range of disabilities, and a person with a disability is defined as anyone with a physical or mental impairment that substantially limits one or more major life activities. These include physical conditions that affect mobility, stamina, sight, hearing, and speech, as well as emotional illnesses and learning disorders. The ADA addresses access of individuals with disabilities to the workplace (Title I), state and local government services (Title II), and places of public accommodation and commercial facilities (Title III). In addition, phone companies are required, under the ADA, to provide telecommunications services for people who have hearing or speech impairments (Title IV).

Title I, which deals with employment of individuals with disabilities, requires that employers do not discriminate against qualified individuals with disabilities and that they reasonably accommodate the disabilities of qualified applicants and employees by modifying work stations and equipment, unless undue burden should result. Title II, which deals with public services, requires that state and local governments do not discriminate based on disability and that they ensure that their buildings are accessible, that new and altered streets and pedestrian walkways contain curb cuts at intersections, and that each service or program is operated so that it is readily accessible to and usable by individuals with disabilities. In addition, this title requires that transit facilities, buses and rail vehicles, key stations in rail systems, Amtrak stations, and vehicles for demand response systems be made accessible, unless certain exceptions apply. Title III, which deals with public accommodations, requires that restaurants, hotels, theaters, shopping malls, retail stores, museums, libraries, parks, private schools, and day care centers, among other places of public accommodation, do not discriminate based on disability. Any alterations to existing places of public accommodation are required to be done in an accessible manner. Moreover, new busses for specified public transportation must be accessible, and elevators must meet certain conditions. Title IV, which covers telecommunications, states that telephone companies must provide telecommunications relay services for hearing-impaired and speech-impaired individuals 24 hours per day.

The ADA has had a significant impact on American society, allowing individuals with disabilities to pursue opportunities that were not available to them in the past. One of the largest groups affected by the ADA is employers, who must both reasonably accommodate the needs of employees with disabilities and refrain from discriminating against them. If an employer fails to comply with the ADA, the employee can sue, forcing the company to comply or pay damages. In addition, state and local government bodies, educational institutions, and virtually any place of public accommodation or employment are directly affected by the ADA and must comply with the regulations.

The Annenberg Washington Program, a nonprofit institute in communication studies, met in 1994 and expanded upon a previously published white paper in which it stated its initial findings that the average cost of most ADA accommodations was approximately $36, a much lower amount than many anticipated. The program found that the impact of the ADA on American businesses did not create onerous legal burdens, as many believed would be the case, but rather has provided a framework for employers and employees for dispute avoidance and resolution. Overall, the ADA has had a positive impact on society.

The ADA has also taken a push approach toward addressing issues of accessibility. The push is for the businesses and organizations themselves to devise solutions based on the requirements set forth in the ADA.

Electronic Industries Alliance (EIA) Standards: EIA- 608 and EIA-708

The EIA-608 standard specifies the use of closed-captions in analog TV signals. EIA-608 addressed the lack of standards for Line 21 closed-captioning, to ensure that new decoders would all work the same way and that captioners could create captions that would appear in a consistent and predictable manner on every TV set. The Television Data Systems Committee of the EIA enhanced the Line 21 system by adding new characters and assigning codes that would allow the center of the screen to be used for captioning. They also allowed roll-up captions, for the first time enabling real-time captions to be placed somewhere other than the bottom of the screen. This work became known as the EIA-608 standard, and all captioning software and all TV receivers built after July 1993 were required to comply with it.

When digital television (DTV) was developed, a new need arose for the ability to change the size of the caption display—making the captions larger and more readable or smaller and less obtrusive. The conversion of closed-captions for service with digital was necessary. This need could not be accommodated in the EIA-608 standard, and thus the EIA-708 standard was introduced. The current version, EIA-708B, covers two areas. It defines how captioned data are to be encoded and transmitted (known as the transmission protocol or transmission layer). It also defines where in a DTV signal the caption data are to be placed, the bandwidth allocated, and the format of the data. The second area is the display protocol, which determines how captions are displayed on the screen of a DTV. The 708 captioning format was designed to allow for the use of the entire unicode set, which includes every character in the alphabet in any language plus the complete range of symbols. Almost any program can thus be captioned.

Many groups are affected by the introduction of the EIA-708 standard. Manufacturers are affected because the Decoder Circuitry Act of 1990 states that “[d]igital television receivers and tuners must be capable of decoding closed-captioning information that is delivered pursuant to the industry standard EIA-708-B.” This Act requires the FCC to update its rules for decoders as new technologies such as DTV are developed. Television broadcasters are also largely affected by the new 708 captioning format, because the pressure is building to produce new programming with digital closed-captions based on this standard. Broadcasters and producers must begin devising plans to make this move and invest in the equipment they will need to do so. Also significantly affected are the viewers with auditory impairments who will benefit from much greater flexibility and a higher quality of captioning with the EIA-708 standard.

A push approach toward the development of a new standard has been taken in the movement from EIA-608 to EIA-708 captioning. After developing the new standard, the EIA put the responsibility on the broadcasters and producers to comply with these standards in their captioning. This push to move from EIA-608 (analog) to EIA-708 (digital) has brought many improvements to closed-captioning. Television viewers can now control the size of the caption text. In addition, EIA-708 offers more letters and symbols, supports multiple fonts and text and background colors, and allows the viewer to replace the traditional black-box background with a colored box or do away with it entirely. Also, EIA-708 increases the data rate by 16 times over that provided by EIA-608, allowing DTV captions to contain much more information. However, most DTV content currently still relies on the EIA-608 standard captions that have been converted to the EIA-708 format, because the consumer base of DTV receivers is not yet high enough to justify the added expense of native EIA-708 encoding.

Individuals with Disabilities Education Act

The Individuals with Disabilities Education Act (IDEA) was first enacted in 1975. The Act was passed to ensure that students with disabilities receive free, appropriate public education and the related services and support they need to achieve in the least restricted environment appropriate to their individual needs. IDEA was created to help states and school districts meet requirements for educating children with disabilities and to pay part of the expenses of doing so. IDEA consists of three parts: Part B provides grants to states for services for preschool and school-age children, Part C funds early intervention services for infants and toddlers, and Part D supports national activities to improve the education of children with disabilities, including research and professional development programs.

IDEA covers children with disabilities until they graduate from high school or until they are 22 years of age if graduation is delayed. Students who may have a covered disability must be evaluated. If it is determined that the student does have a disability covered by IDEA, the school is required to annually develop an individualized education program (IEP) for the student and place him or her in a regular classroom setting when possible. Amendments to the Act adopted in 1997 have shifted the focus of IDEA from merely providing children with disabilities access to an education to improving results for all children in the education system.

The primary group affected by and benefiting from IDEA are children with disabilities. As a result of IDEA, students with disabilities now learn among their peers. U.S. Senator Jim Jeffords reports that since the initiation of IDEA, dropout rates for students with disabilities have significantly declined and graduation rates have gone up. The percentage of college freshman with disabilities has tripled as a result of the improved education children with disabilities have available to prepare them for college. Teachers and parents of children with disabilities are also significantly affected by IDEA. These two groups play a large role in the development of a child’s IEP. Teachers have had to adjust to having children with disabilities in the same classroom as children without disabilities, learning together. Others involved in the public education system are certainly affected as well.

The enactment of IDEA has followed a push approach in requiring that public schools make free education that adheres to the provisions set forth in the Act available to students with disabilities. The legislation places the responsibility upon the schools and provides them with the requirements they must meet, while providing some financial assistance.

Instructional Material Accessibility Act

The purpose of the Instructional Material Accessibility Act of 2003 (IMAA) is to improve access to printed instructional materials used by students in elementary and secondary schools who are blind or have other visual disabilities. The Act creates an efficient system for the acquisition and distribution of instructional materials in the form of electronic files suitable for conversion into a variety of specialized formats. IMAA requires one national file format and a single national repository for files, which simplifies the process of obtaining materials for students with disabilities. Having a national file format will make the conversion process for producing specialized formats more efficient by reducing the amount of human intervention necessary. Having one national file format will make it easier for states, publishers, Braille software developers, and Braille transcribers to work with files. Braille transcribers will have more time to use their expertise in formatting and proofing files, leading to high-quality Braille. Students will directly benefit because the national file format will eliminate needless steps in scanning and reformatting files. Teachers will benefit, as well, by having materials available in specialized formats for their students who have disabilities at the same time they are available to their other students.

State and local education agencies that receive federal funding under IDEA are responsible for developing a statewide plan within two years of the enactment of IMAA to ensure that printed materials required for classroom instruction in elementary and secondary schools are available in specialized formats to individuals with disabilities at the same time they are made available to students without disabilities.

This Act is a push approach toward improving access to printed instructional materials for visually impaired students. IMAA requires all the states to adopt the national file format.

Video Description Restoration Act

The Video Description Restoration Act (VDRA), which is pending in Congress, would restore the FCC’s video description rules that were overturned in federal court on November 8, 2002. The Act would guarantee TV access for individuals who are blind or visually impaired through video description. The FCC would be expressly granted authority to restore its minimum requirements, with increased access over time. Those minimum requirements mandated that the major networks and cable channels in the top 25 television markets present at least four hours of described programming per week and that video-described programs be made available in smaller markets where TV stations have the equipment to do so. VDRA has been rigorously supported by the American Council for the Blind and other blind and deaf organizations, because they feel that video description will achieve for people who are blind what closed-captioning does for individuals who are deaf.

The community of people who are blind or visually impaired would benefit from VDRA by once again having video description available to them, affording them the same access to information on television as sighted viewers. Also affected would be the television program providers and owners who would be required to offer video description for a portion of their programming. VDRA permits an exemption if the provision of video description would be unduly burdensome to the provider or owner, or if video description is not necessary to achieve video programming accessibility by persons who are blind or otherwise visually impaired.

VDRA would restore the FCC’s rule for the minimum requirements major networks and cable channels must meet in terms of the amount of video description they provide. This push approach taken by the FCC would ensure that at least a portion of programs would be made available for the visually impaired through video description. The number of hours of video description mandated by the FCC may grow larger, leading to increased access to television programming for the visually impaired over time.

Standards and Guidelines

In addition to the laws mentioned in the previous section, standards and guidelines exist that drive more accessibly designed E&IT. These are discussed below.

ADA Accessibility Guidelines

The Access Board’s guidelines, issued under the Americans with Disabilities Act, are to be completely updated and revised. The ADA Accessibility Guidelines (ADAAG) cover the construction and alteration of facilities in the private sector (places of public accommodation and commercial facilities) and the public sector (state and local government facilities). The accessibility guidelines issued under the Architectural Barriers Act (ABA) primarily address facilities in the federal sector and other facilities designed, built, altered, or leased with federal funds. The guidelines under both laws are being updated together in one rule that contains three parts: a scoping document for ADA facilities, a scoping document for ABA facilities, and a common set of technical criteria that the scoping documents will reference. As a result, the requirements for both ADA and ABA facilities will be more consistent. The guidelines also include new scoping and technical provisions for accessible housing that derive from requirements for “Type A” dwelling units contained in the 1998 edition of the ICC/ANSI A117.1 standard, “Accessible and Usable Buildings and Facilities.” Of specific interest is 4.34.5 Equipment for Persons with Vision Impairments. Instructions and all information for use must be made accessible to and independently usable by persons with vision impairments.

Telecommunications Act Accessibility Guidelines

On February 3, 1998, the Access Board issued its final guidelines for the accessibility, usability, and compatibility of telecommunications equipment and customer premises equipment covered by section 255 of the Telecommunications Act of 1996 (Telecommunications Act Accessibility Guidelines, 1998). The Act requires manufacturers of telecommunications equipment and customer premises equipment to ensure that the equipment is designed, developed, and fabricated to be accessible to and usable by individuals with disabilities, if readily achievable. When it is not readily achievable to make the equipment accessible, the Act requires manufacturers to ensure that the equipment is compatible with existing peripheral devices or specialized customer premises equipment commonly used by individuals with disabilities to achieve access, if readily achievable.

Web Content Accessibility Guidelines 1.0

These guidelines explain how to make Web content accessible to people with disabilities (Web Content Accessibility Guidelines 1.0, 1999). The guidelines are intended for all Web content developers (page authors and site designers) and for developers of authoring tools. The primary goal of these guidelines is to promote accessibility. However, the adoption of these guidelines will also make Web content more available to all users, no matter what user agent they are using (e.g., desktop browser, voice browser, mobile phone, automobile-based personal computer) or constraints they may be operating under (e.g., noisy surroundings, under- or over-illuminated rooms, in a hands-free environment). The adoption of these guidelines will also help people find information on the Web more quickly. These guidelines do not discourage content developers from using images, video, and so on, but rather explain how to make multimedia content more accessible to a wide audience.

Authoring Tool Accessibility Guidelines 1.0

This specification provides guidelines for Web authoring tool developers (Authoring Tool Accessibility Guidelines 1.0, 2000). Its purpose is twofold: to assist developers in designing authoring tools that produce accessible Web content and to assist developers in creating an accessible authoring interface. Authoring tools can enable, encourage, and assist users (“authors”) in the creation of accessible Web content through prompts, alerts, checking and repair functions, help files, and automated tools. It is just as important that all people be able to create content as it is for all people to have access to it. The tools used to create this information must therefore be accessible. Adoption of these guidelines will contribute to the proliferation of Web content that can be read by a broader range of readers and authoring tools that can be used by a broader range of authors.

User Agent Accessibility Guidelines 1.0

This document provides guidelines for designing user agents that lower barriers to Web accessibility for people with visual, hearing, physical, cognitive, and neurological disabilities (User Agent Accessibility Guidelines 1.0, 2002). User agents include HTML browsers and other types of software that retrieve and render Web content. A user agent that conforms to these guidelines will promote accessibility through its own user interface and through other internal facilities, including its ability to communicate with other technologies (especially assistive technologies). Furthermore, all users, not just users with disabilities, should find conforming user agents to be more usable. In addition to helping developers of HTML browsers and media players, this document will also benefit developers of assistive technologies because it explains what types of information and control an AT may expect from a conforming user agent. Technologies not addressed directly by this document (e.g., technologies for Braille rendering) will be essential to ensuring Web access for some users with disabilities.

XML Accessibility Guidelines

This document by the World Wide Web Consortium (W3C) provides guidelines for designing Extensible Markup Language (XML) applications that lower barriers to Web accessibility for people with visual, hearing, physical, cognitive, and neurological disabilities (XML Accessibility Guidelines, 2002). XML, used to design applications such as XHTML, SMIL, and SVG, provides no intrinsic guarantee of the accessibility of those applications. This document explains how to include features in XML applications that promote accessibility.

Customer Analysis

The purpose of this section is to highlight the consumer markets targeted by the industries being studied. A more detailed customer analysis can be found in the appendix to the online version of this report.

People with Disabilities

Estimates vary greatly on the number of persons with disabilities living within the United States and worldwide. The latest Census Bureau disability statistics report, Characteristics of the Civilian Noninstitutionalized Population by Age, Disability Status, and Type of Disability: 2000, estimates that there are 49.7 million people with disabilities living in the United States (Age Structure, 2003). Applying the disability percentages presented in this report to the age structures categorized by the World Factbook (including populations less than five years of age), results in a figure of 54 million, which is often cited as the actual number of people with disabilities living in the United States. This is the figure reported by the NCD (2004). Comparing the U.S. disability statistics with those of other countries indicates that China, India, Russia, Mexico, and Turkey have greater instances of disabilities for any age category because they have poorer health care than the United States. The market for universally designed products and services seems clear when global disability statistics (498 million people) are analyzed for these countries, which currently have the top five emerging markets. A detailed look at these emerging markets can be found in the appendix to this report online.

The specific customer populations of interest for the purpose of this study are people with the following disabilities or conditions:

• Low vision

• Blind
• Hard of hearing
• Deaf
• Upper-mobility impaired
• Lower-mobility impaired
• Cognitive

Each of the above conditions is defined in terms of a loss of functional capability that may be temporary or permanent or may develop as a natural part of the aging process. The functional limitations may be caused by genetics, disease, traumatic injury, aging, environmental or situational factors, or some combination of multiple factors. In other words, the analysis is not restricted to functional limitations resulting from what is traditionally termed a disability. This approach, espoused by the functional model of disabilities (Kaplan, n.d.), allows us to consider a wide segment of the population who could truly benefit from universal design.

It is important to understand the functional capabilities and limitations, as well as alternative strategies of access, of the target population in order to properly assess the impact of various accessibility features on mainstream products. Each of the target populations has different functional capabilities and limitations and thus experiences different issues with the product lines under study.

Visual Impairments

In general, people with impaired vision may have difficulty perceiving visual detail, focusing on objects either close up or at a distance, separating objects that do not have sufficient contrast, perceiving objects in both central and peripheral vision, perceiving color and contrast brightness, adapting to different light levels, tracking moving objects, and judging distances (Story, Mueller, and Mace, 1998).

Hearing Impairments

In general, people who are deaf and hard of hearing may have difficulty localizing the source or direction of sound, filtering out background sound, perceiving both high- and low-pitched sounds, and carrying on a conversation (Story, Mueller, and Mace, 1998).

Mobility Impairments

In general, people with impaired mobility may have difficulty with tasks requiring range of motion, coordination, strength, and balance. More specifically, difficulties may be apparent in the following areas: reaching, pushing, pulling, lifting, lowering, carrying, grasping, squeezing, rotating, twisting, and pinching (Story, Mueller, and Mace, 1998).

Cognitive Disabilities

In general, people with cognitive disabilities may have difficulty “…receiving, comprehending, interpreting, remembering, or acting on information” (Story, Mueller, and Mace 1998). More specifically, difficulties may be apparent in the following areas: beginning a task without a prompt or reminder, responding within an appropriate time frame, concentrating, comprehending visual or auditory information, understanding or expressing language, following procedures or doing things in order, organizing information, remembering things, making decisions and solving problems, and learning new things and doing things a new or different way (Story, Mueller, and Macel, 1998).

Other Customer Markets

In addition to people with disabilities, other customer markets targeted in this study include the following. A discussion of each of these customer populations can be found in the appendix to the online version of this report.

• Individuals 65+ years of age
• Consumers living in low-bandwidth information infrastructures
• People who have never learned to read
• Users of ESL
• Tourists
• Consumers living in high-density populations
• Consumers in situations that reduce sensory or visual capabilities

Analysis of Market Trends

The market for E&IT products is constantly changing and evolving as new product trends arise. New trends in cellular phones, ATMs, PDAs, televisions, speech recognition technology, and distance learning are changing the way we learn, do business, store data, bank, communicate with others, and entertain ourselves. There are many market forces that reflect the desires of the E&IT industry (such as gaining a competitive advantage and complying with U.S. laws) and of the consumer (such as wanting easy-to-use products that are efficient and increase the user’s safety). These forces create the demand for more accessibly designed products. New products are consistently emerging with the aim of serving a wider population of users, including users with various disabilities, and increasing the overall ease of use for everyone. Current trends in the industries for the six product lines presented in this report are discussed below, along with the market forces that create the demand for those products. Information in this section of the report comes from many different sources, all of which are cited in the text.

Cell Phones

Scarborough Research, the nation’s leader in local, regional, and national consumer information, estimates that “almost two-thirds (62 percent) of American adults own a cell phone” (McFarland, 2002). Most cell phones are used to make telephone calls, surf the Web, and receive messages. Cell phones are invaluable in an emergency. They have helped save people’s lives, whether assisting in locating people involved in an airplane crash or enabling people to call for help when faced with a medical emergency. Many people use them for long-distance calling instead of signing up for a long-distance plan through their home telephone service provider. Cell phones give people the ability to surf the Web without a computer, take a photo and immediately send it to someone else, and receive messages, stock quotes, news, and other information anywhere, anytime.

Market Forces Creating Demand for More Accessibly Designed Cell Phones

1. The desire on the part of the E&IT industry to achieve competitive advantage and increase profits. Desire on the part of consumers to purchase the most convenient and easy-to-use cell phone. Examples of these market forces include the following innovations:

— Easier data entry: The desire to enter text into a cell phone easily was a major market driver in making cell phones more accessible. Until recently, entering a single character (i.e., A–Z) into a cell phone required up to six key presses. For example, you would have to press the #2 key six times and then the #key to select and enter a capital C. Here is, in order, what each key press would do: First press = a, second press = A, third press = b, fourth press = B, fifth press = c, sixth press = C, and # enters the character. Consumer demand led to the development of new cell phone keypads. For example, the Fastap™ keypad is an extremely simple, intuitive, and powerful computer interface that fits in a small mobile phone. Modern phones offer a lot more than just voice communication. Mobile phones are data devices with the ability to write messages, collect and store information, and buy things. They are essentially networked computer terminals. Alphanumeric keypads make a cell phone easier to use for people with low vision (Fastap, n.d.).

— Voice dialing: Voice dialing is a common feature on most digital cell phones. The technology has gone even further. iVoice, Inc., recently released a new hands-free feature to its Speech Enabled Auto Attendant that allows outbound callers to speak the number they wish to dial (iVoice, Inc., 2003).

— Talking caller ID: Most people would like to know who is calling them before answering their cell phone, especially if they are occupied in an eyes-busy, hands-busy, environment. Lucent Technologies offers talking caller ID in support of helping wireless network operators rapidly deploy new features and generate new revenues (Cambridge Telecom Report, 2000).

— Automatic ring mode adjustment: A cell phone that is aware of where it is and adjusts its ring mode accordingly is being patented by IBM’s research lab in Winchester, MA. The new system uses global positioning system (GPS) technology to switch the phone’s ringing modes. In “region definition” mode, the phone stores its current GPS coordinates while the owner tells it whether to ring loudly, quietly, vibrate, or divert to an answering service. This can be done separately in several locations—home, work, church, and your favorite bar, for example—so the phone knows exactly how to behave at that location. (Note: The cell phone industry is already building GPS receivers into handsets so that emergency services can locate callers.)

— Large fonts: Samsung’s SCH-T300 can display numbers in a large font. (Samsung, n.d.).

— Bluetooth communications: Bluetooth comes built into products consumers use every day—like cell phones, headsets, PDAs, laptops, and, yes, even cars—and it allows devices that have Bluetooth built in to “talk” to each other without a wire connection. If a cell phone and headset both have Bluetooth built in, the user could put the headset on and leave the phone in his or her pocket. Bluetooth can also connect a car to the driver’s Bluetooth-enabled cell phone. The phone in this scenario connects to the car’s audio system, and dash-installed controls take over the function of the phone. Calls are made and retrieved using voice recognition, and the user never has to touch the actual phone (Auto Channel, 2003).

2. The desire on the part of the E&IT industry to comply with federal laws. The desire on the part of consumers to be safe, get help in case of an emergency, and maintain contact with young children, aging parents with Alzheimer’s, or others at risk. Examples of these market forces include the following advancements:

— Global positioning system feature: Facing a federal requirement to provide location data to 911 dispatch centers by 2005, cell phone carriers have developed a GPS system to track wireless calls. A special chip in the phone times the signals from three satellites to calculate its position, which is relayed to the nearest 911 center (LaGeese, 2003). GPS-equipped cell phones can also be used to maintain contact with young children, aging parents with Alzheimer’s, or others at risk, or to find out if your children are where they say they are when you call them.

— Cellular phone with built-in optical projector for display of data: A patent for a cellular phone that is compact in size and weight includes a mechanism for displaying received wireless data in its original page format, as sent from the original source. This allows for viewing each original page as a whole page, rather than as a series of partial pages. The phone also allows the display of received wireless visual data with characters in their true original size, thus allowing for ease of reading and use.

Market Forces Reducing the Accessibility of Cell Phones

1. The desire on the part of the E&IT industry to achieve competitive advantage through innovation. Desire on the part of consumers to purchase distinctive cell phones suited to a personal sense of style. Examples include the following:

— Miniaturization. Many cellular phones are being designed to be more portable and less obtrusive. As a result, keypads have shrunk, making it difficult for users who are blind to tactilely identify keys. In addition, users without fine motor control skills have difficulty activating the smaller keys.

— Nonstandard keypads. Some stylized phones have keypads arranged in a circular pattern or other nonstandard layout. Users who are blind find it difficult to identify the keypad keys because they are not arranged in the familiar layout.

2. The desire on the part of the E&IT industry to achieve competitive advantage and increase profits. Desire on the part of consumers to purchase the most advanced, feature-rich cell phone. The following is an example:

— Smart phones. There is a trend to integrate PDA functionality with cellular phones. The complexity of the user interface and the dexterity required to operate the smart phone may place the phone beyond the capabilities of some users.

ATM Machines

The classic definition of an automated teller machine (ATM) is an unattended machine, external to a bank, that dispenses money when a personal coded card is used. There are more than 200 million users of ATMs in the United States. Billions of transactions are processed in the United States yearly. According to Grant Thornton LLP, there are 350,000 ATMs in the United States; 250,000 are in nonbank locations, and 150,000 of these ATMs are owned by nonfinancial companies (Grant Thornton, 2003).

ATMs have revolutionized the way most people do their banking. Customers can take care of financial transactions at any time of the day or night without having to go to a bank building per se, since ATMs are readily available at supermarkets, convenience stores, shopping malls, hotels, and many other public places. ATMs are used for cash withdrawals, transferring money between accounts, looking up account balances, depositing cash and checks, purchasing money orders, obtaining credit-card advances, and purchasing stamps. Talking ATMs have enabled people who are blind to experience the convenience of anytime banking. In the future, ATMs will be able to send person-to-person “cash” payments, cash checks, deposit cash immediately into your account, and be accessed by a cell phone or PDA.

Market Forces Creating Demand for More Accessibly Designed ATMs

1. The desire on the part of the E&IT industry to comply with U.S. and international laws. Examples of legal requirements that have prompted accessibility include the following:

— United States: ADA Accessibility Guidelines for Buildings and Facilities (ADAAG) as amended through September 2002: Section 4.34 Automated Teller Machines [4.34.5] Equipment for Persons with Vision Impairments states, “Instructions and all information for use shall be made accessible to and independently usable by persons with vision impairments (Access Board, n.d.).

— United States: Section 707 of ICC/ANSI A117.1 Standard on Accessible and Usable Buildings and Facilities is entitled “Automatic Teller Machines (ATMs) and Fare Machines.” Although the 2003 version of this document has not yet been finalized or published, the following is an example of preliminary wording (in part): “Speech Output Machines shall be speech enabled. Operating instructions and orientation, visible transaction prompts, user input verification, error messages, and all displayed information for full use shall be accessible to and independently usable by individuals with vision impairments. Speech shall be delivered through a mechanism that is readily available to all users including, but not limited to, an industry standard connector or a telephone handset. Speech shall be recorded or digitized human, or synthesized” (International Code Council, n.d.).

— Australia: The Australian Bankers’ Association (ABA), the Human Rights and Equal Opportunity Commission (HREOC), and the Accessible E-Commerce Forum worked with representatives from member banks, other financial institutions, community groups, suppliers and retailers, and the National Office for the Information Economy’s (NOIE) Access Branch to develop a set of voluntary industry standards to improve the accessibility of electronic banking (Australian Bankers’ Association, n.d.).

— United Kingdom: Access to ATMs: UK Design Guidelines provides research-based information to ensure that ATMs meet the needs of all users. The guidelines are based on ergonomic research and testing, offering design principles and guidance for those who design, manufacture, install, and maintain ATMs. The 2002 edition reflects and builds on the experience gained from advances in the design of ATMs and the practical application of the 1999 edition (Feeney, 2003).

2. The desire on the part of the United Nations and the World Bank to reduce poverty in developing countries by helping those countries grow and prosper. The desire on the part of the E&IT industry to achieve competitive advantage and generate revenue from emerging markets. The desire on the part of consumers in developing countries to have the basic necessities of life. Examples of these market forces at work include the following:

— The unbanked: ATMs can be a channel for the flow of money that is being kept “under the pillows” of billions of people living in emerging market areas who do not have a bank account. There also are about 11 million consumers in the United States who do not have bank accounts (Cipherwar.com, 2000). Delton Yuen, NCR’s vice president, Financial Solutions Division, Asia-Pacific, stated, “If every household saves money in pillowcases or a cookie jar, the economic system is going to have less money to go around to fund capital investments. For countries to ensure that the economy grows, they need capital. And when the money within a country is not channeled into the financial system or banking system, that capital is circulating less and less” (McGill, 2002).

— Talking ATMs: Although these devices are being developed for people who are blind, they can also accommodate people who cannot read. There are 440 million people who cannot read living in the top five emerging markets.

Personal Digital Assistants

PDAs store, analyze, and retrieve needed information on demand, anytime and anywhere. A PDA can be used as a calculator, address book, calendar, memo pad, expense tracker, and an electronic information storage device. They serve as portable personal computers and augmentative communications devices. Some of the many industries using PDAs are health care, building/construction, engineering, restaurant, and sales. PDAs are useful for dispatching crews and managing mobile personnel. While they are particularly useful in the business world, they are excellent memory aids for individuals. Information can be transferred between the PDA and a personal computer, providing portable access to information. PDAs are also being used for leisure-time activities. They can provide golfers with distance measurements and scorecards. It is also possible to watch a movie on your PDA. Gartner Group predicted worldwide PDA revenue would be $3.53 billion in 2003, or approximately 10 million new units shipped worldwide (Directions Magazine, 2003a).

Market Forces Creating Demand for More Accessibly Designed PDAs

The primary force is the desire to minimize the cost of doing business. PDAs are now replacing what were once expensive, proprietary, industry-specific telecommunication devices. Another force is the desire of consumers to maximize the ease of use of PDAs in eyes-busy, hands-busy environments. Professionals using PDAs in eyes-busy, hands-busy environments are likely to find PDAs more user-friendly and easier to use if they are equipped with voice recognition and text-to-speech technologies. Examples of improvements resulting from these market forces include the following:

• Health care: Wireless-equipped PDAs have been embraced by the medical community to access medical records, write electronic prescriptions, and use as a portable nursing-unit terminal. PDAs are also replacing high-cost medical devices. CardioNet developed a proprietary PDA-type electrocardiogram monitoring device connected to electrodes on a patient’s chest. The PDA receives signals from the electrodes and transmits data to the PDA device (CardioNet, n.d.).
• Public safety: Field officers use Internet-ready PDAs to access remote records from management databases. This helps to improve the efficiency of creating incident reports. It also optimizes the transfer of queries and responses (Directions Magazine, 2003b).
• Workforce management: Cobb EMC is an electric cooperative serving more than 170,000 customers in five metropolitan Atlanta counties. Cobb EMC uses PDAs to dispatch crews. The cooperative claims that this has helped to streamline work processes and increase service reliability (Directions Magazine, 2003c).
• Military: Applications and devices developed for use by the military include the V3 Rugged PDA; industry-leading handheld capabilities; integrated Bluetooth for wireless link to phones, printers, and PCs; TFT screen with 64K colors; Windows CE-based Pocket PC with IBM ViaVoice, MS Pocket Office, and other applications (General Dynamics, n.d.).
• Multimedia industry: Pocket PC Films, in Sherman Oaks, California, uses PDA technology to distribute video content for Pocket PC and Palm OS devices. Film fans can buy CD-ROM titles, load them on their computers, and sync them into their handheld devices. Pocket PC Films now distributes 25,000 titles. The huge potential market to use PDAs to view high-quality multimedia has led manufactures to equip them with high-quality audio capabilities. For more information, access the following Web site: http://store.yahoo.com/pocketpcfilms/xsxtremwinsp.html.
• Assistive technology industry: In order to reduce the cost of their products, several AT vendors are replacing their proprietary augmentative communications device hardware with PDAs. The touchscreen, text-to-speech, and voice recognition capabilities of PDAs make this possible. Two vendors in particular are pioneering this trend. They are Enkidu Research with its Palmtop Portable and Saltillo with its ChatPC.
• Simplified writing interfaces: Written Chinese has 6,000 characters. A computer keyboard has 47 character keys. Chinese data entry is so difficult that there is an entire industry of people who make their living as typists. Someone who is really good with the Chinese version of Microsoft Word (which takes the simplified “pinyin” transliteration and guesses at the character the writer means) can type maybe 20 words a minute. Until, that is, PDA manufacturers started to equip PDAs with better chips and faster algorithms. Voice interfaces are becoming so powerful that the Mandarin PDA-based language recognizer can distinguish about 40,000 words and still not tax the memory or processing power of the PDA (Kumagai, n.d.).

Televisions

A television is technically described as a telecommunication system that receives, decodes, and displays images and plays audio of objects, stationary or moving, broadcast from a separate transmitter. Television is the medium that entertains, informs, and educates; it can also serve as a companion to people who, because of circumstances beyond their control, are confined to their homes. Traditionally, people have used TVs to get news reports and watch movies, sports events, and sitcoms. Cable TV is a telecommunication system that receives, decodes, and displays images and plays audio of objects, stationary or moving, broadcast over cable directly to the receiver. With cable TV, people have many more options of channels to watch, some devoted to a particular subject of interest, such as HGTV for the home and garden enthusiast or news broadcasts 24 hours a day. In addition, movies can be purchased on a pay-per-view basis. Technologically advanced TV systems allow viewers to play interactive games, take a distance learning course, send instant messages, surf the Web, send an email, and shop for and purchase products, including movie tickets and CDs from talk shows and concerts.

HDTV (high-definition television) is a system that has more than the usual number of lines per frame, resulting in pictures that show more detail. Interactive television (iTV) provides richer entertainment, interaction, and more information pertaining to the shows, props, and people involved in its creation. In a sense, it combines traditional TV viewing with the interactivity enjoyed by those communicating through a network, such as the Internet. According to Disney, its iTV program, “Disney Active Portal on Sky Digital,” is a major step forward. It offers Disney more flexibility and control of its interactivity in terms of design and dynamic update. The new application empowers kids, giving them the opportunity to participate in shows while still being able to watch the action on screen.

Market Forces Creating Demand for More Accessibly Designed Televisions

1. The desire on the part of the E&IT industry to comply with U.S. laws. Examples of how these market forces resulted in enhanced products and services include the following:

— Emergency programming: FCC rules require broadcasters and cable operators to make local emergency information accessible to persons who are deaf or hard of hearing and to persons who are blind or have visual disabilities. This means that emergency information must be provided both orally and in a visual format. Video programming distributors include broadcasters, cable operators, satellite television services (such as DirecTV and the Dish Network), and other multichannel video programming distributors (FCC, 1999).

— Captioning: Congress first instituted the requirement that television receivers contain circuitry designed to decode and display closed-captioning. As of July 1993, the FCC required that all analog television sets with screens 13 inches or larger sold in the United States contain built-in decoder circuitry that allows viewers to display closed-captions. Beginning July 1, 2002, the FCC also required that digital television (DTV) receivers include closed-caption display capability. As part of the Telecommunications Act of 1996, Congress instructed the FCC to require video program distributors (cable operators, broadcasters, satellite distributors, and other multichannel video programming distributors) to phase in closed-captioning of their television programs. In 1997, the FCC implemented rules to provide a transition schedule for video program distributors to follow in providing more captioned programming. The rules require that distributors provide an increasing amount of captioned programming according to a set schedule. All English language programming prepared or formatted for display on analog television and first shown on or after January 1, 1998, as well as programming prepared or formatted for display on digital television that was first published or exhibited after July 1, 2002, is considered “new programming” and must be captioned according to benchmarks set by the FCC. The following benchmarks establish how much new programming must be captioned each calendar quarter:

> January 1, 2000, to December 31, 2001: 450 hours of programming per channel per quarter

> January 1, 2002, to December 31, 2003: 900 hours of programming per channel per quarter

> January 1, 2004, to December 31, 2005: 1350 hours of programming per channel per quarter

> January 1, 2006, and thereafter: 100 percent of all programming, with some exemptions

— Digital television TV mandate: The FCC has issued a ruling that requires DTV licensees to simulcast 50 percent of the video programming of their analog channel on their DTV channel by April 1, 2003. This requirement increases to 75 percent on April 1, 2004, and 100 percent on April 1, 2005. The simulcasting requirement was intended to ensure that consumers enjoy continuity of free, over-the-air video programming service when the analog spectrum is reclaimed at the end of the transition. With digital transmission, a TV broadcaster will be able to

> Send multiple programming at the same time over the same channel

> Improve the quality of the transmission with options not available with analog transmission

> Offer digital data services, which will allow the TV broadcaster to send out virtual newspapers and other types of services directly to your TV

2. The desire on the part of the E&IT industry to achieve competitive advantage and generate revenue.

— Word-search videos using closed-captions: The need to produce just-in-time news stories used to cause problems for broadcasters. When a major event occurred, news programs would have to scramble around looking for some footage that supported the subject of the news story. For example, when an entertainer passes away, news programs might show a clip or two of the last interview with that individual. It could be very time-consuming to search through logs and libraries to find the appropriate footage. That is, until broadcasters gained the ability to both store digital copies of their broadcasts on computers and conduct word searches on them using the captions. Captioning their programming has enabled many news broadcasters to achieve a competitive advantage in the marketplace by being the first to announce a breaking event with the appropriate video content.

Voice Recognition

Voice recognition technology (VRT) by itself is neither accessible nor inaccessible. It is the integration of VRT into other products and services that can help to make those products and services more accessible and usable. VRT, also referred to as speech recognition technology (SRT), provides telecommunications and computing devices with the ability to recognize and carry out voice commands or take dictation. VRT is generally identified as either being speaker dependent or speaker independent. Speaker-dependent systems recognize only a particular individual’s voice and are often used in dictation products. Speaker-independent systems can recognize multiple voices. Speaker-dependent systems are better able to process an individual’s quirky speech patterns, but they can take a significant amount of time to train. There are also continuous versus discrete speech recognition systems, in which, respectively, the user can talk at a normal rate or is required to talk with pauses between words.

Voice recognition enhances quality of life and independence for many people. Users do not have to use their hands when operating a telecommunications device that incorporates VRT. This technology is also useful in a hands-busy environment, such as when a radiologist analyzes x-rays by holding them up to the light and verbally dictates the results to a computer. It is also helpful when operating small devices such as cell phones and PDAs.

Many industries are adding VRT to their communication systems as a way to lower operational expenses by cutting the costs of call handling. In 1996, Charles Schwab became the first major consumer company to offer voice recognition for its customers to get stock quotes and other information at the customer’s convenience. In addition to brokerage houses, the banking, health care, law enforcement, travel, transportation, and entertainment industries, to name just a few, are also incorporating VRT.

The Market Forces Creating Demand for More Accessible and Usable VRT

1. The desire on the part of the E&IT industry to achieve competitive advantage. The desire of consumers to purchase easy-to-use and convenient products. The following is an example of an innovation resulting from these market forces:

— Voice dialing: People trying to operate a cell phone in an eyes-busy, hands-busy, environment might experience difficulty. This market factor led to the incorporation of VRT into cell phones and the development of hands-free accessories for cell phones. People with upper mobility disabilities, people with low vision, and many senior citizens can also benefit from voice dialing. Voice dialing is a common feature on most digital cell phones. PCS-Direct, an Internet-based phone store, carries nine different cell phones equipped with voice dialing (PCS-Direct, n.d.).

2. The desire on the part of the E&IT industry to reduce cost and employee turnover. The desire on the part of call-center agents to make their jobs as pleasant and nonrepetitive as possible. Examples of innovations resulting from these market forces include the following:

— Interactive voice response (IVR) systems: To date, companies have attempted to handle interactions with their customers using touch-tone IVR systems, but customers are not entirely satisfied with this form of interaction. Touch-tone interfaces are both frustrating and ineffective. In order to support customer interactions more quickly and efficiently, companies are beginning to move to speech recognition systems. Many call centers use systems that combine digitized speech and speech recognition. Using IVR systems costs much less than using call-center agents. Thanks to IVR, customer requests can be handled with little human intervention. Call-center agents can then become more productive doing other things. Another benefit of IVR is that agents no longer need to repeat the same information to each caller, over and over again. This tends to increase employee satisfaction and reduce turnover. “Following this, the market is believed to be on its way to being worth $43 billion by 2007” (Telecomworldwire, 2002).

— Web-based voice portals: VRTs can be used to enable people to access a Web site using a telephone. Extending access to a commercial Web site by telephone can attract new customers who may not be in a position to use a computer connected to the Internet. There are many instances of this use. For example—

> People operating from within low-bandwidth infrastructures

> People who never learned to read

> Mobile professionals who need quick access to information while on the go

> Senior citizens who recognize the value of the Internet but are simply more comfortable using a telephone

> People who are blind or visually impaired

> People who are traveling and don’t have access to their PCs

— VoiceXML standards: The VoiceXML Forum is an industry organization established to promote VoiceXML as the universal standard for speech-enabled Web applications. The VXML Forum “aims to drive the market for voice- and phone-enabled Internet access by promoting a standard specification for VXML, a computer language used to create Web content and services that can be accessed by phone.” Following standards breeds success and enhances the compatibility and interoperability of your system with others. Systems that have been developed according to standards are easier and less expensive to maintain.

— Dictation, voice recognition, and transcription: Many professions require the transcription of voice-recorded data. These professions include law enforcement, medicine, and the legal profession. The financial pressures to drive transcription costs down and productivity rates up helped to fuel the $8 billion speech recognition industry.

Distance Learning

“Distance learning is used in all areas of education, including pre-K through grade 12, higher education, home school education, continuing education, corporate training, military and government training, and telemedicine” (USDLA, n.d.). Students participating in distance learning can use the learning style of their choice. Audio-based classes can consist of recordings, synthesized speech, and audio-conferencing. Video-based learning includes video and videoconferencing and Webcasting. Print-centered techniques include online texts, books, and handouts. Employers also benefit when their employees participate in distance learning courses. “Travel expenses are reduced or eliminated, there is increased productivity as employees don’t need to leave the office for extended periods of time, teams are brought together without restrictions on schedule or location, and it provides the ability to reach geographically dispersed populations with a uniform and consistent approach” (Thunderbird, n.d.). Also, higher education facilities are finding that distance learning is less expensive to support than traditional classroom learning.

The types of technologies for implementing distance learning include “two-way video with two-way audio (two-way interactive video), one-way video with two-way audio, one-way live video, one-way prerecorded video (including prerecorded videotapes provided to students and TV broadcast and cable transmission using prerecorded video), two-way audio transmission (e.g., audio/phone conferencing), one-way audio transmission (including radio broadcast and prerecorded audiotapes provided to students), Internet courses using synchronous (i.e., simultaneous or real-time) computer-based instruction (e.g., interactive computer conferencing or Interactive Relay Chat), Internet courses using asynchronous (i.e., not simultaneous) computer-based instruction (e.g., e-mail, listservs, and most World Wide Web-based courses), CD-ROM, multimode packages (i.e., a mix of technologies that cannot be assigned to a primary mode), and other technologies” (Tabs, 2003, p. 11). Online education is now offered at more than 56 percent of the nation’s two- and four-year colleges and universities, with distance learning beginning to extend to high schools and lower.

Market Forces Creating Demand for More Accessibly Designed Distance-Learning Technology

1. The World Bank and its members want to reduce poverty and strengthen emerging economies: American businesses have invested more than $250 billion in the top 15 emerging markets with the sincere belief that they will yield significant returns on their investment. Distance education is a critical success factor in human development in emerging markets. Some call it the foundation of business success in emerging markets. Education provides the high-level skills necessary to establish a growing, self-sustaining E&IT labor market. It can also provide the training required by engineers, doctors, teachers, nurses, business entrepreneurs, social scientists, and many other professionals critical to the success of maturing a developing economy.

The information infrastructures supporting a majority of distance learning activities in emerging markets are low-bandwidth environments. Many of their resources will need to operate over wireless devices. This means that the content will need to be developed in an accessible manner.

Billions of workers live in emerging markets. They are the individuals who ultimately benefit from an effective distance-learning infrastructure. However, in the top five emerging markets, there are 440 million people who can’t read. In order to benefit from distance learning, the materials need to be provided in alternate formats.

2. Corporations want to educate their employees more effectively and less expensively: Distance learning produces a 60 percent faster learning curve than traditional instruction. More than 6,000 U.S. companies offered distance learning courses to their employees in 2003, up from 391 in 1998. The U.S. corporate skills business training market is projected to reach $18.3 billion by 2006 (compounded annual growth rate [CAGR] of 13.3 percent). Worldwide, the distance-learning IT education and training market is projected to reach $28.6 billion by 2006 (CAGR of 7.1 percent).

3. Universities want to reduce costs, increase enrollment, and still offer a quality education. Conservatively, there are 45 million users of online higher education. By 2025, the global demand for online education is forecast to reach 160 million students. For every foreign student studying in the United States, there are three to five students who would access U.S. education online if they could (Moe, 2002).

4. The law: Many countries have policies relating to Web accessibility. They are Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Italy, Japan, New Zealand, Portugal, Spain, the United Kingdom, and the United States of America. The European Union also has Web-access policies. Distance learning usually takes place via the Web (Web Accessibility Initiative, n.d.). Several countries have detailed policies that specifically apply to education, as described here:

— Australia has a Disability Discrimination Act (1992) that applies to education.

— Canada’s Charter of Rights and Freedoms guarantees the basic rights and freedoms important to Canada as a free and democratic society. The Canadian Government has also established a Common Look and Feel for Canadian Government Web sites, which includes accessibility provisions.

— The UK’s Special Educational Needs and Disability Act took effect on September 1, 2002. The Act removes the previous exemption of education from the Disability Discrimination Act (1995), ensuring that discrimination against students with disabilities will be unlawful. Institutions incurred additional responsibilities in 2003, with the final sections of legislation coming into effect in 2005.

The following U.S. policies make accessibility a requirement for distance learning:

— ADA and section 504: Two federal laws govern accessibility of education: Title II of the ADA and section 504 of the Rehabilitation Act of 1973 (as amended in 1998). All elementary, secondary, and postsecondary educational institutions are regulated under these laws. A useful legal analysis of the requirements is provided in the California Community Colleges’ Distance Education Access Guidelines (California Community College, 1999).

— Section 508: To ensure that its technology is accessible to its own employees and to the public, the Federal Government has created regulations based on section 508 of the Rehabilitation Act that require that E&IT developed, procured, maintained, or used by the Federal Government be accessible to people with disabilities. These regulations apply to all federal purchases of technology. Requirements in section 508 may also affect state colleges and universities, pending policy decisions from the Department of Education’s Office of Civil Rights.

— California higher education requirements: The California Community College system has released Distance Education Access Guidelines and Alternate Media Access Guidelines. The Alternate Media Access guidelines serve as a guide for the implementation of California Law AB422, requiring publishers to provide textbooks in electronic format to the three systems of higher education in California (the University of California, the California State University, and the California Community Colleges). The Distance Education Access Guidelines include a summary of legal requirements as well as access guidelines for specific modes of distance education instructional delivery. These documents and other resources are available from the High Tech Center Training Unit of the California Community Colleges.

— Texas K-12 textbook adoptions: Texas has for several years been studying the issue of access to electronic books and educational software for students with disabilities. Two reports, one issued in 1997 and one in 1999, provide information on how educational materials can be made accessible. Texas requires publishers to provide electronic files for adopted print materials and is in the process of incorporating the federal section 508 requirements as an optional part of its adoption process for interactive educational software and electronic textbooks. Further information about Texas textbook accessibility is available from the Texas School for the Blind and Visually Impaired.

III. Product Analysis

This section documents the primary findings of a detailed product line analysis for each of the product lines selected for study. The purpose of this research is to document accessibility issues that prevent people with disabilities from fully accessing the selected products and to document accessibility features that are either currently offered or potentially could be offered by manufacturers. For a more detailed discussion of the product line analysis, including a discussion of the product lines broken down according to different disability types, consult the appendix to the online version of this report at http://www.ncd.gov.

The accessibility of a given product is based primarily on a determination of access to core features of the product, with some consideration for additional features that enhance the product but are not necessary for use of the product for its primary purpose. For this research, both accessible and UD features are considered. Accessible design is defined as the design of products that makes them accessible to people with disabilities without requiring the purchase of additional equipment or specialized training. Universal design, or design for inclusion, is the design of products and environments to make them usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. A disability is considered any restriction or lack of ability, resulting from an impairment, to perform an activity in the manner or within the range of activity considered standard for a human being.

Under section 508, each federal department or agency, including the U.S. Postal Service, when developing, procuring, maintaining, or using E&IT, must ensure that the E&IT allows—

• Federal employees with disabilities to have access to and use of information and data comparable to the access to and use of information and data by federal employees who do not have disabilities.
• Individuals with disabilities who are members of the public seeking information or services from a federal department or agency to have access to and use of information and data comparable to the access to and use of information and data by members of the public who are not disabled.

Section 508 applies without regard to the medium of the technology. However, section 508 permits exceptions if an undue burden would be imposed upon the agency or department.

In general, section 508 requires that products be—

• Usable by people who are blind
• Usable by people with low vision without relying on audio
• Usable with little or no color perception
• Usable by people who are deaf
• Usable by people with limited hearing
• Usable by people with limited manual dexterity, reach, and/or strength
• Usable with time-dependent controls or displays
• Usable by people without speech
• Usable by people with limited cognitive or memory abilities
• Usable by people with language or learning disabilities
• Available with audio cutoff (private listening)
• Designed to prevent visually induced seizures

• Available with biometric identification/activation bypassing

• Usable by people with upper extremity prosthetics

• Hearing aid compatible

• Usable from a wheelchair or similar personal vehicle

Also, section 508 requires compatibility with peripheral devices and that accessibility of information, documentation, labeling, and support be provided to customers. Section 508 provides guidelines for software applications and operating systems, Web-based Internet information and applications, telecommunications products, video and multimedia products, self-contained closed products, desktop and portable computers, and functional performance criteria.

Product designers should consider features that facilitate the following capabilities: Users with visual impairments need to be able to identify, differentiate, and operate all controls and displays, without accidentally activating undesired controls; they should be able to detect control activation and outcome; they should not be required to depend on color to differentiate control and display states to successfully use the device. Users with hearing impairments need to be able to acquire information via a nonauditory format, detect control activation and outcome, and use assistive listening devices. Users with mobility impairments need to be able to view, reach, and activate all controls and displays; manipulate levers, drawers, panels, and all controls; activate controls without accidentally activating adjacent controls; activate controls with the use of an assistive device; and have sufficient time to enter commands. Finally, users with cognitive disabilities need to be able to understand the controls and displays and have sufficient time to enter commands.

Product Line Assessment Methodology

The product line assessment provides an identification of accessibility issues within each product line and an assessment of accessibility features designed to address specific issues. The assessment of accessibility issues involves the calculation of an “impact score” for each issue and target population. The impact score is an estimation of the affect of a particular accessibility issue on a particular target population. The score is calculated at the task level based on two separate dimensions. The first dimension, task priority, is defined as a measure of task importance. High-priority tasks are those that are essential to the device, while low-priority tasks are defined as those that are not essential or would not be expected to be performed by the end-user. The second dimension, accessibility, is defined as an estimation of the ability of a user with a given set of functional capabilities and limitations to satisfactorily complete a given task. Accessibility is classified at three levels: little or no difficulty, some difficulty, or great difficulty. After impact scores are calculated from the priority and accessibility level for each task, they are used to assign an accessibility grade to each product line for each target population.

Product Line Assessments

The sections below describe the results of the product line assessments. Each product line section is organized as follows: background, accessibility features, compliance with government regulations, and conclusions.

Part of the product line assessment included conducting a task-based accessibility analysis for each product line. A detailed discussion of this task-based accessibility analysis is available in the appendix to the online version of this report. The task-based accessibility analysis consists of identifying the core functionality (tasks) for the product line, identifying the priority level for each task, and assigning a task-accessibility estimation for each task. The task-accessibility score is derived from expert evaluations, a Georgia Tech survey on universal design, and user testing. The combination of the task-priority levels and the task-accessibility estimation is used to calculate an impact score, which is then used to create an accessibility grade for the product line. These accessibility grades appear at the conclusion of this section of the report.

Please note that reference herein to any specific commercial product, process, or service by trade name, trademark, manufacturer, or otherwise does not constitute or imply endorsement by the National Council on Disability.

ATM Machines

Despite their popularity and capabilities, ATMs are not accessible by everyone. People who have visual disabilities may have difficulty reading the display and providing accurate inputs. People who have a mobility disability may have difficulty approaching the device, reaching the controls, and reading the display. People who have cognitive disabilities may have difficulty reading the display and understanding the options. Each of these challenges can be overcome, to some extent, through proper design.

Task-Based Accessibility Analysis

The core functionality considered necessary to effectively use an ATM consists of the following:

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, or the design of the ATM. Accessibility issues for the disability population were identified, along with an impact rating for each issue. The disability populations include people who have an impairment resulting from environmental or situational factors. The issues identified and impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various ATM manufacturers’ marketing data produced a number of features identified as accessible design components. Each of these components is listed, along with a description of the component and an assessment of the usefulness of the feature for disability groups. Some of these features may have been designed with a particular disability population in mind; others may have been designed simply as desirable features. In many cases, the accessibility features benefit or are used by a variety of people, and they may be considered to provide universal access.

Large sunlight-readable color display: ATM displays can be very difficult for the average person to use simply because of lighting issues, natural or otherwise. Sunlight often creates glare on electronic displays, sometimes making it impossible to even discern that any text appears on the display. In some cases this can be overcome by shifting the viewing orientation, but this is not an option for all people. Sunlight-readable displays can increase accessibility by preventing glare. With the exception of people who are blind, this will have a medium impact for all users and will help solve the problem of not being able to receive visual information.

Touchscreen display: Touchscreens provide the manufacturer with a method of creating a dynamic display, providing more information in less space. Touchscreens can be designed with large, high-contrast buttons or icons that can provide an alternative solution for those with partial visual impairment or motor disabilities. Selection via large touch areas on the screen may be preferable to some users as an alternative to keyboard or function key input. Additionally, for users with complete vision loss, touchscreen functions can be mapped—or directed—down to the tactile keyboard. But unless the functions are mapped in this way, or an alternative audio interface is provided, touchscreens are not accessible to people who are blind and will have a negative impact. If keyboard mapping is implemented or an alternative audio interface is provided, touchscreens will have no impact on people who are blind. They will have a medium impact for those with low vision and mobility impairments if implemented with large touch areas and text or graphics. If good graphical metaphors are used, touchscreens will have a medium positive impact for the cognitively disabled. They will help solve the problem of making inputs and possibly of receiving and interpreting visual information.

Talking ATM: A talking ATM is one with voice displays. Talking ATMs are useful in circumstances in which it is difficult to read the text display because of a visual impairment, low reading ability, significant glare on the screen, or possibly having to view the screen from a seated position. Inclusion in design will have a high impact for those who are blind, a medium impact for those with low vision or cognitive disability, and a low impact for all other users. It will help solve the problem of receiving and interpreting visual information.

Private headphone jacks for talking ATM: Voice instructions can be provided publicly, or privately through the use of headphones. Voice instructions can help guide the user through the transaction and provide information such as feedback on keypress entries and account balance (things that would typically be presented visually). This would allow a person who is blind to perform an ATM transaction independently, although it is likely that audio feedback would not be available for PIN entry for security reasons. This would probably be an inconvenience for the user but would not prevent use of the ATM. Implementation in design will have a high impact for people who are blind, a medium positive impact for users with low vision, and a neutral impact for other users. Choice of private audio will help solve the problem of not being able to receive auditory or visual information.

Mapping function keys to the keypad: This is a software feature that allows the function keys at the side of the ATM display to be mapped, or directed, down to the keyboard. This means that the user can perform the entire transaction from the keyboard, which minimizes the distance a user has to stretch to reach the keys. It also helps people who are blind by providing a more familiar key layout to use for input. Function key mapping will have a medium impact for people who are blind and people who have upper or lower mobility impairments, and a neutral impact for all others. It will help solve the problems of not being able to locate or identify controls and not being able to make inputs.

Raised tactile symbols: Raised tactile symbols help those with visual impairments, particularly if they are blind, distinguish keys that most people differentiate through a text label or graphic. In some cases, these symbols may include a Braille keypad, although Braille proficiency is not widespread. Other alternatives include protruding keytips, which enable the visually impaired to feel the edge of individual keys and so determine the end of one key and the start of another, and increased character size, to assist those with visual impairments. Implementation in design has a neutral impact for most users, but a medium impact for those who are vision impaired. It will help solve the problem of not being able to locate and identify controls.

Raised area (nib) on the “5” key: A nib is a raised area that helps users identify the location of the center of the keypad so they can then determine the position of the remaining keys. Given a standard telephone keypad layout with the addition of nonnumeric keys, the nib helps the user (particularly the user with a visual impairment) find the “5” key, from which the remaining numeric keys can be easily identified. Inclusion in design will have a high impact for users who are blind, a medium impact for those with low vision, and a neutral impact for other users. It will help solve the problem of not being able to locate and identify controls.

Keys on the keypad that are discernible by touch: Tactile separators typically provide either raised or indented spaces between controls to assist in tactile differentiation of numeric keys from other keys. Inclusion in design will have a high impact for those who are blind, a medium impact for those with upper mobility impairments, and a low impact for all others. It will help solve the problems of not being able to locate and identify controls and not being able to make accurate inputs.

Tactile feedback keypad: Tactile feedback results from the keys springing back to position once pressed, indicating that a key has been pressed and input accepted. Touchscreens, for example, do not have tactile feedback. Inclusion in design will have a high impact for people who are blind, a medium positive impact for those with low vision, and a low impact for other users.

User-controllable playback speed: User-controllable speed allows the user to make adjustments to auditory output to meet information processing needs. Visual output tends to be available until the next selection is made, but auditory output is temporal, and user control allows review of information as needed. This is particularly beneficial to people who are blind and perhaps to some users with low vision or cognitive disabilities. Implementation in design will have a medium positive impact for people who are blind and a low impact for other users. It will help solve the problem of difficulty receiving auditory information.

User-controllable volume: Volume control allows the user to make adjustments to auditory output to meet sound level needs, particularly in noisy environments. This is particularly beneficial to the hard of hearing. Implementation in design will have a high positive impact for the hard of hearing and a low impact for other users. It will help solve the problem of difficulty receiving auditory information.

Visual alert: Visual alerts may be in the form of a change in text display or a light. They serve as an alternative or supplement to vibrating and auditory alerts. Visual indicators are particularly beneficial for people who are deaf or hard of hearing. Inclusion in design will have a high impact for users who are deaf, a medium impact for those who are hard of hearing, and a low impact for all others. They will help solve the problem of not being able to receive auditory information.

Pause control for talking ATM: Pause control allows the user to pause the verbal output from the device. This is helpful to give one time to write something down or to think about what option might be desired. Inclusion in design will have a medium impact for users who are blind and a low impact for all other users. Pause control will help solve the problem of not being able to read text on the screen.

Replay control for talking ATM: Replay control allows the user to listen to a message more than once. This is helpful if the voice output was not understood or could not be heard over environmental sounds. Inclusion in design will have a medium impact for users who are blind or hard of hearing and a low impact for all other users. Replay control will help solve the problem of not being able to read text on the screen.

Voice recognition for talking ATM: Voice recognition allows a user to speak in his or her voice to make inputs to the device. This is particularly useful for those who cannot physically activate the controls or who cannot tactilely differentiate the controls to know, for example, which button to press. Inclusion in design will have a high impact for users who are blind, a medium impact for users with low vision and upper mobility impairments, and a low impact for all others. Voice recognition will help solve the problems of not being able to locate, identify, and activate the controls.

ATM that can be controlled by a cell phone or PDA: External control of the ATM allows individuals to use their own personal accessible device to interact with an ATM that may not otherwise be accessible for a particular disability type. Inclusion in design will have a medium impact for users who are blind, have low vision, or have an upper mobility impairment and a low impact for all other users. PDA or cell phone control will help solve the problems of not being able to read text on the screen or to locate, identify, and activate the controls.

Large keys for the keypad: Large keys on the keypad increase the ability to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have poor fine motor control and a low impact for all other users. It will help solve the problem of having difficulty making accurate inputs.

Large fonts on the display: Large fonts on the display increase the text size for circumstances in which small text is difficult to read. Inclusion in design will have a high impact for those with low vision, a low impact for users who are blind, and a medium impact for all other users. It will help solve the problem of not being able to read text on the screen.

Large display screen: Large display screens reduce screen clutter and increase the space available for larger text and graphics. Inclusion in design will have a medium impact for low-vision users and a low impact for all others. It will help solve the problem of not being able to read text on the screen.

High-contrast display: High contrast provides the option for users to adjust the color or brightness of the foreground and background colors so that the text stands out from the background, increasing readability. Inclusion in design will have a high impact for those with low vision and most users under very bright- or low-light conditions. It will have a low impact for other disability populations. High contrast will help solve the problem of not being able to receive visual information.

Ability to request additional time: Ability to request additional time allows the user to complete a transaction despite the need to use more than the normal amount of allotted time to complete individual transaction components. Inclusion in design will have a high impact for most users, depending on the output mode (visual or auditory) from the device. Additional time will help solve the problems of not being able to receive visual or auditory information, not being able to reach controls, and not being able to grasp objects.

Graphical instructions: When good metaphors are used and display resolution is sufficient, graphical instructions may be easier to see than text instructions, particularly if the font size for text is small. Inclusion in design will have a medium impact for those who have low vision and a low impact for all other users. Graphical instructions will help solve the problem of not being able to read text on the screen.

Text equivalents for auditory information: Text equivalents are a means of providing redundant information so that someone who has difficulty with one sense (in this case, hearing) has an alternative method of obtaining the information being provided (in this case, through eyesight). Inclusion in design will have a high impact for those who are deaf or hard of hearing and a low impact for all other users. Text equivalents will help solve the problem of not being able to receive auditory information.

Detachable controls: Detachable controls provide the option for individuals to place the control panel in their laps, for example, limiting the amount of reach required to activate the control, increasing the ability to support the hand and arm, and possibly making the difference between being able to use the device or not. Inclusion in design will have a high impact for those with those with a lower mobility impairment or any user operating the ATM while seated in a wheelchair, and a low impact for all other users. Detachable controls will help solve the problem of not being able to reach the controls from a seated position.

More space between keys on the keypad: More space between the keys increases the ability to differentiate the keys by touch and to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. It will help solve the problem of having difficulty locating controls and making accurate inputs.

Concave keys on the keypads: Concave or curved-inward keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. This type of key also increases the ability to differentiate the keys from each other and from the surrounding area on the device. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Concave keys will help solve the problem of locating controls and making accurate inputs.

Keys that can be operated without human contact: Some individuals use pointing devices or other mechanisms to help them reach or activate controls. Some devices require moisture content or heat (characteristics of touch) to activate the controls; these devices cannot be used by someone who needs to use an alternative input device. Controls that are operable without physical human contact will have a high impact for someone with an upper mobility impairment and a low impact for all other users.

Rubberized keys: Rubberized keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. Textured keys also help the user differentiate the key itself from the surface of the device, particularly if the keys are not raised sufficiently. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Rubberized keys will help solve the problem of locating controls and making accurate inputs.

Additional features that may enhance accessibility include the following:

Type of card reader—swipe, dip, or motorized: These are typically accompanied by tactile indicators and flashing lights to assist in card insertion. People with different capabilities may benefit more from one type of reader than another. For example, a vertical card swipe may be difficult for someone with limited reach. It may be difficult for users without fine motor control to retrieve a fully inserted card (dip card reader) from the device. Users who are blind may have difficulty finding the card reader or determining the proper orientation of the card. Implementation of a certain style will have a high impact for users who are blind or have upper mobility impairments. Use of a motorized reader or a horizontal swipe with tactile cues will help solve the problem of having difficulty inserting the ATM card into the machine.

Customer telephone: This can be used to acquire human assistance if the customer has difficulties using the ATM. A customer telephone will have a low impact for all users. It can help solve the problems of not being able to receive visual information or not being able to locate and identify controls.

Digital video camera: This can be used in conjunction with the customer telephone to allow the customer service representative to see the customer’s difficulty. A digital video camera will have a low impact for all users. This can help solve the problems of not being able to receive visual information or not being able to locate and identify controls.

Multilingual capability: Multilingual capabilities will help those who have difficulty operating the ATM because of unfamiliarity with the language. This will have a medium impact for users with cognitive disabilities. It may help solve the problem of not being able to interpret visual information.

LED indicator: LEDs provide a visual indication of status information, or they may provide guidance on what to select next or where to insert an object. They serve as an alternative or supplement to vibrating and auditory alerts. Visual indicators are particularly beneficial for people who are deaf or hard of hearing. They will have a low impact for all other users, and will help solve the problem of not being able to receive auditory output.

User manuals in alternative formats: Alternative formats include large print, Braille, and audio. Inclusion in design will have a high impact for users who are blind or have low vision and a neutral impact for other disability populations. It will help solve the problems of not being able to read or handle printed materials.

Compliance with Government Regulations

The primary parts of section 508 that are applicable to ATMs address self-contained, closed products (1194.25); functional performance requirements (1194.31); and documentation (1194.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another.

The following section 508 regulations are seen as issues for ATMs:

• Verify that all controls and keys are tactilely discernible without activating the controls or keys. Some ATMs only use touchscreens, which are counter to this regulation.
• Verify that at least one mode of operation and information retrieval is provided that does not require user vision or, alternatively, that support is provided for assistive technology used by people who are blind or visually impaired. The majority of ATM information is provided through a text display, which cannot be seen by a user who is blind.

• At least one mode of operation and information retrieval that does not require visual acuity greater than 20/70 must be provided through audio and enlarged print output working together or independently; otherwise, support for AT used by people who are visually impaired must be provided. ATMs do not always provide voice output and often use font sizes smaller than 14 points, which is inadequate for someone with low vision.
• At least one mode of operation and information retrieval that does not require fine motor control or simultaneous actions and that is operable with limited reach and strength must be provided. ATMs are often mounted at a height that is difficult or impossible for people in a seated position to access. The level of the display and control panel varies from one ATM to the next, and some are better suited to individuals in wheelchairs than others.

Cell Phones

Despite their popularity and their capabilities, cell phones are not accessible to everyone. There are limitations that make cell phones either inaccessible or difficult to use (and, therefore, possibly undesirable). People who have visual impairments may have the most difficulty reading the display and accessing visual information. People who are deaf or hard of hearing may have difficulty carrying on a verbal conversation and detecting auditory alerts. People with a mobility disability may have difficulty making accurate inputs and simultaneously handling the phone and manipulating the controls. People who have cognitive disabilities may have difficulty understanding metaphors that are used and remembering how to access information. Each of these problems can be overcome, to some extent, through proper design.

Background

Digital cellular telephone service is growing rapidly in the United States because of the advantages it offers over older analog service. Digital service allows for more users, less expensive service, higher sound quality, more features, and better security. There are different types of digital cellular technology, including code-division multiple access (CDMA) and several varieties of time-division multiple access (TDMA), global system for multiple communications (GSM), and integrated digital enhanced network (iDen). The particular type of digital technology in use varies by service provider.

The introduction of digital cellular telephone service in the mid-1990s also introduced a new access barrier for people who wear hearing aids. Analog systems work fairly well with teletype devices (TTYs). Some phones have built in modular jacks into which a TTY can be plugged; other phones can be used with an adapter. Initially, digital systems did not work well with TTYs. Digital wireless transmissions inherently contain errors, but error correction techniques can reduce the problem for speech. Digital networks are less forgiving in the case of the tones generated by TTY devices, however, and the transmission errors can cause characters to be lost or changed, resulting in unintelligible messages.

When digital cellular telephones are in close proximity to hearing aids, interference may be heard through the hearing aid. The interference may be perceived as a buzzing, humming, or squealing inside the hearing aid. This interference does not occur with all combinations of telephone, hearing aid, and cellular service; but when it does occur, it can make use of the telephone annoying, difficult, or impossible. In general, older, larger hearing aids are more susceptible to interference than newer models. Studies have shown that a distance of one to two feet between the phone and the hearing aid will reduce or eliminate the interference in most cases.

The electromagnetic field surrounding the antenna of the telephone is the primary source of interference. Moving the antenna farther from the hearing aid may reduce or eliminate interference. The loudness of the interference also depends on the power of the transmission, which in turn varies with the distance from the telephone to the cellular base station. “Flip phone” designs may reduce interference by placing the antenna farther from the hearing aid and by shielding the hearing aid from the antenna. But the antenna is not the only source of interference; internal telephone electronics, such as the back light on the screen, can also cause interference.

Possible solutions from the cellular industry may include reducing the required transmission power by adding more base stations, improving antenna technology and shielding the telephone, and providing accessories such as neckloops that induce sound into the T-coil of hearing aids without requiring proximity of the telephone to the hearing aid.

Possible solutions from the hearing aid industry include increased shielding of hearing aids and modification of the circuitry and design of hearing aids to minimize interference.

Digital Cell Phone Compatibility with TTY

In 1996, the FCC issued a requirement that wireless carriers be capable of connecting 911 calls over a digital wireless network for callers using a TTY. The deadline for compliance was extended repeatedly as various wireless carriers worked to provide a solution.

Since September 1997, the TTY Forum (sponsored by the Alliance for Telecommunications Industry Solutions, or ATIS) has worked to develop technically feasible solutions that will enable TTY users to make TTY calls over digital wireless systems. The TTY Forum is composed of various stakeholders, including wireless carriers, wireless handset manufacturers, wireless infrastructure manufacturers, manufacturers of TTYs, 911 and telecommunications relay service providers, and consumer organizations representing people with hearing and speech disabilities.

In January 2000, Lucent Technologies announced a solution for TTY access using digital cellular telephones. The solution was developed by the Bell Labs Speech and Audio Processing Technologies group; it involves upgrading software in both the network and the handset. The software detects the TTY characters being sent and repeatedly transmits those characters to the receiving end, allowing the receiving end to correctly regenerate the tones corresponding to the characters.

At its meeting on June 4, 2002, the TTY Forum announced that many wireless service providers were prepared to meet the FCC’s June 30, 2002, deadline for TTY compatibility, and that testing had shown that digital wireless TTY consistently performed better than TTY over analog circuits. To enable the TTY calls over digital voice channels, digital wireless handsets and networks had to be redesigned to accommodate the speed and tone of TTY Baudot signals. Numerous problems had to be overcome, including setting standards for the interface between TTY devices and digital wireless mobile phones operating with several different digital standards.

However, while wireless TTY compatibility services work well for nonemergency communication, at the time of the announcement there were some remaining issues for emergency situations. Wireless 911 TTY calls may suffer high character error rates when received by some public service answering points (PSAPs). Test results from the ATIS-sponsored TTY Technical Standards Implementation Incubator show that the problem encountered may be related to older and nonstandardized TTY equipment or software used by some PSAPs. The wireless telecommunications industry performed due diligence to ensure that the digital network would be capable of transmitting TTY calls by the June 30, 2002, deadline and was committed to continue to work to provide access to 911 for its customers using TTYs. There is some indication that wireless networks now support digital TTY with compatible phones, but this cannot be verified since it is illegal to test 911 services. A number of carriers petitioned the FCC for an extension to the 911 requirements.

Hearing Aid Compatibility with Cellular Telephones

The Hearing Aid Compatibility Act of 1988 (HAC Act) required the FCC to ensure that all telephones manufactured or imported for use in the United States after August 1989, and all “essential” telephones, were hearing aid compatible. Secure telephones and mobile telephones were exempt from the HAC Act, however.

In November 2001, the FCC released a Notice of Proposed Rulemaking to reexamine the exemption of mobile phones from the requirements of the HAC Act. On August 14, 2003, the FCC released a Report and Order modifying the exemption for wireless phones under the HAC Act to require that digital wireless phones be capable of being used effectively with hearing aids.

The FCC ruling requires digital wireless phone manufacturers to make available within two years at least two HAC-compliant handsets with reduced radio frequency (RF) emissions for each air interface (e.g., CDMA, TDMA, GSM) they offer. It also requires each carrier providing digital wireless services, except for nationwide (Tier I) wireless carriers, to make available to consumers within two years at least two HAC-compliant handset models with reduced RF emissions for each air interface it offers.

Nationwide (Tier I) wireless carriers must offer within two years two HAC-compliant handset models with reduced RF emissions for each air interface they employ or ensure that one quarter of their total handset models are HAC-compliant with reduced RF emissions within two years, whichever option yields a greater number of handsets.

Digital wireless phone manufacturers must make available to carriers within three years at least two HAC-compliant models with telecoil coupling for each air interface they produce, and each carrier providing digital wireless access must make available to consumers within three years at least two HAC-compliant handset models with telecoil coupling for each air interface it offers.

Further, one-half of all digital wireless phone models offered by a digital wireless manufacturer or carrier must be compliant with the reduced RF emissions requirements by February 18, 2008. Manufacturers must label packages containing compliant handsets and must make information available in the package or product manual. Service providers must make available to consumers the performance ratings of compliant phones.

In addition, the FCC established an exemption for digital wireless manufacturers and carriers that offer a minimal number of handset models. The FCC encourages digital wireless phone manufacturers and service providers to offer at least one compliant handset that is a lower-priced model and one that has higher-end features, and encourages hearing aid manufacturers to label their precustomization products according to the American National Standards Institute (ANSI) standard.

On September 5, 2003, ATIS established the ATIS Hearing Aid Compatibility Incubator. The ATIS HAC incubator consists of a diverse mix of wireless service providers, wireless manufacturers, hearing aid manufacturers, and other parties. The mission of the HAC incubator is to investigate performance between hearing aids and wireless devices to determine methods of enhancing interoperability and usability for consumers with hearing aids.

On October 1, 2003, DAMAX, a manufacturer of cellular telephone antennas, announced a line of directional antennas that show promise for improving the hearing aid compatibility of existing handsets.

Task-Based Accessibility Analysis

The core functionality considered necessary to effectively use a cell phone consists of the following:

• Locating the cell phone
• Identifying the current state of the phone: on or off
• Turning the phone on and off
• Locking the phone
• Unlocking the phone
• Dialing numbers on the keypad
• Storing a phone number
• Recalling a stored phone number
• Receiving a phone call
• Receiving caller-ID information
• Accessing voice mail
• Attaching a headset
• Using a headset
• Determining battery status
• Determining signal strength
• Detecting when the phone is in roam mode
• Receiving a text message
• Sending a text message
• Charging the phone

Additional functionality that is typically inherent in cell phone design includes the following:

• Using a calculator
• Playing games

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, and the design of the phone. Accessibility issues for each disability population were identified, along with an impact rating for each issue. The disability populations include people who have an impairment resulting from environmental or situational factors. The issues identified and impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various cell phone manufacturers’ marketing data produced a number of features identified as accessible design components. Each of these components is listed, along with a description of the component and an assessment of the usefulness of the feature for disability groups. Some of these features may have been designed with a particular disability population in mind; others may have been designed simply as desirable features. In many cases, the accessibility features benefit or are used by a variety of people, and they may be considered indicative of universal access.

Loopset for hearing aids: A loopset is an accessory that increases clarity and reduces background noise when translating from sound over the telephone line to a hearing aid device. Inclusion in design will have a high impact for users who are hard of hearing and who use T-coil equipped hearing aids and will help resolve the issue of not being able to receive verbal information. Availability of loopsets will have no impact for other disability populations.

Voice dialing: Voice dialing provides users with the option to speak the name of the person they want to call rather than using numeric dialing or accessing a name from the directory. Inclusion in design will have a high impact for people who are blind and a medium positive impact for users with low vision and upper mobility impairments. It will have a low impact for other disability groups. All users (except perhaps the speech impaired) may find the feature useful. Although voice dialing is not likely to increase accessibility under general circumstances, it will in some situational contexts in which the user’s hands are unavailable. This is an example of a feature that is nearly universally usable, but it should not replace traditional dialing methods; voice dialing may be problematic for people without speech, people with laryngitis, or in noisy environments. Voice dialing will help resolve the issues of not being able to locate or identify controls and not being able to make accurate inputs.

Adjustable contrast: Adjustable contrast provides the option for users to adjust the color or brightness of the foreground and background colors on the display screen to increase clarity and readability. Inclusion in design will have a high impact for those with low vision and most users under very bright- or low-light conditions. It will have a low impact for other disability populations. Adjustable contrast will help resolve the issue of not being able to receive visual information.

Roller key: The roller key provides an alternative to successive button presses, allowing the user to slide the thumb or finger over a roller in order to scroll through contents on a screen. This is an example of a feature that is nearly universally usable, but it should not replace traditional navigation methods. Inclusion in design will have a low impact for all disability groups.

User manual in alternative formats: Alternative formats include large print, Braille, and audio. Inclusion in design will have a high impact for those who are blind or have low vision and a neutral impact for other disability populations. It will help resolve the issues of not being able to read or handle printed materials.

One-touch dialing: One-touch dialing provides the option to map phonebook entries to numeric keys. Once programmed, the key can be pressed for an extended period of time to dial the phone number rather than dialing in full or navigating through the phonebook. This is a desirable feature for all people, regardless of disability. Inclusion in design will have a high impact for people with upper mobility impairments (if they can sustain the key press) and visual impairments and a low impact for all other users. It will help resolve the issues of locating or identifying controls and making accurate inputs.

Customized ring tones/alerts: Ring-tone options provide the user with a choice regarding the ring sound that is heard when there is an incoming call. In some cases, the phone can be set to ring differently for different callers. Customized alerts provide the user with a choice of the sound or tone that is heard when different alerts (e.g., reminders) are triggered. This user profiling is particularly useful for individuals who are blind who may not otherwise be able to determine the source of an incoming call, and inclusion in design will have a medium-high positive impact. Certain ring tones may be more perceptible than others for the hard of hearing, and inclusion of ring-tone options in design will have a medium impact for this group and will help resolve the issue of not being able to receive acoustic alerts and signals. While inclusion for other disability groups does not affect accessibility, ring-tone options are a highly desirable feature. Different ring tones also help users distinguish their own cell phone ring from someone else’s.

Text-based functionality: Similar to sending email, text messaging via cell phone provides a mobile communication mechanism and has become highly popular. It allows individuals to communicate in noisy environments and when verbal conversations are inappropriate. It is particularly beneficial for people who are deaf or hard of hearing, who may not be able to hold a verbal conversation. Cell phones with text messaging and dedicated text messaging devices are very popular among users who are hearing impaired. However, text messaging is a somewhat slower communication method, and it is difficult to share and perceive emotion accurately from text messaging. Inclusion in design will have a high impact for people who are deaf or hard of hearing and low impact for other population groups. Text messaging will help resolve the issue of not being able to receive auditory information by providing a viable alternative.

Vibrating alerts and visual indicators: Vibrating alerts are an alternative to auditory alerts. Vibrating alerts are valuable for all users in various situational contexts, such as a business meeting; but they really enhance accessibility for people who are hard of hearing and deaf, who may not otherwise be able to detect an incoming call. Inclusion in design will have a high impact for users who are deaf, a medium impact for users who are hard of hearing, and a low impact for all other users. Vibrating alerts will help resolve the issue of not being able to receive auditory information. Visual indicators may be in the form of a change in text display or a light. They serve as an alternative or supplement to vibrating and auditory alerts. Visual indicators are particularly beneficial for people who are deaf or hard of hearing . Inclusion in design will have a high impact for users who are deaf, a medium impact for those who are hard of hearing, and a low impact for all others. Visual indicators will also help resolve the issue of not being able to receive auditory information.

Cradle that attaches to mobility aid: A mobile holder is a mounting mechanism that can be attached to a wheelchair or other mobility aid or installed in a car to provide a consistent, secure place to store the cell phone. It also facilitates one-handed dialing by eliminating the need to simultaneously hold the phone and manipulate the controls. Mobile holders are particularly useful for people with upper mobility impairments. Inclusion in design will have a high impact for this group and a low impact for other groups, and it will help resolve the issue of not being able to lift and hold the device.

Raised area (nib) on the “5” key: A nib is a raised area that helps users identify the location of the center of the keypad so they can then determine the position of the remaining keys. Given a standard telephone keypad layout with the addition of nonnumeric keys, the nib helps the user (particularly the user with a visual impairment) find the “5” key, from which the remaining numeric keys can be easily identified. Inclusion in design will have a high impact for users who are blind, a medium impact for those with low vision, and a neutral impact for other users. It will help resolve the issue of not being able to locate and identify controls.

Keypress feedback: Tactile feedback results from the keys springing back to position once pressed, and it is typically accompanied by a clicking sound. Both feedbacks are indicators that the key has been pressed and input accepted. Touchscreens lack both tactile and tonal feedback. Inclusion of keypress feedback in design will have a high impact for those who are blind, a medium impact for those with low vision, and a low impact for other users.

TTY compatibility: A TTY is a small device with a keyboard that allows the user to type input rather than speak. This is then transmitted to the person on the other end of the line, who must also have a TTY device or use a relay service to translate from text to voice. Inclusion of TTY compatibility in design will have a high impact for people who are deaf or hard of hearing and a neutral impact for other users. It will help solve the issue of not being able to receive auditory information. Text messaging is a good alternative to TTY if all parties have access to it.

Voice tag for menu navigation: Voice tags are spoken commands that can be used to bypass keypress inputs to control the phone. Voice tag use is quite common, though it is most beneficial for those with vision and mobility impairments who might otherwise not be able to make accurate inputs. Inclusion in design will have a high impact for these groups and a low impact for all others. It will resolve the issues of not being able to locate and identify controls, not being able to receive visual information, difficulty with inputting information, and difficulty finding desired features.

Zoom display: A zoom display provides the option to increase the text size, reducing the number of lines of text available at any given time. Inclusion in design will have a medium impact for users with low vision and a low impact for others. It will help resolve the issue of not being able to receive visual information.

Brightly backlit display: Backlighting provides the option to adjust the screen lighting to accommodate low-light conditions. This is useful for all individuals in some contexts and is useful for users with low vision in a wider variety of conditions. Inclusion in design will have a medium impact for users with low vision and a low impact for all other users. It will help resolve the issue of not being able to receive visual information.

Adjustable volume: Volume control is important for both auditory alerts and conversation. It is particularly important for hard-of-hearing people, but it is useful for all. Inclusion in design will have a medium impact for hard-of-hearing people and a low impact for all other users. It will help resolve the issue of not being able to receive auditory information.

Icon/graphic menu: Pictorial representations as text alternatives generally allow for more information to be presented on a single screen. They are particularly useful for people who might have a reading impairment. They also provide the opportunity to declutter the screen, which is useful for users who have low vision or cognitive disabilities (if good metaphors are used). Inclusion in design will have a medium impact for users with low vision and users with cognitive disabilities (unless implemented with poor metaphors, in which case it may have a negative impact for users with cognitive disabilities). This will help resolve the accessibility issue of difficulty interpreting textual information.

Audio cue capability: Audio alerts are typically used to identify conditions such as a low battery. They are most useful for those with vision impairments and others in low-light conditions. Other people enjoy auditory displays and will use them, though they do not enhance their accessibility. Inclusion in design will have a high impact for people who are blind, a medium impact for those with low vision or upper mobility and cognitive disabilities, and a low impact for all others. It will help resolve the issue of not being able to receive visual information.

External audio output (via headset): External audio output allows the user to carry on a conversation without needing to hold the phone. Amplified headsets enhance the sound output to increase the clarity of the information. Amplification is not strictly volume level, but more an intensity of different signals. Headsets help to concentrate the sound at the ear while blocking out some environmental noises. External audio is particularly useful for people who have upper mobility disabilities; if implemented in design, it will have a high impact. If the headset is amplified, it will have a high impact for hard-of-hearing users and will help resolve the issue of not being able to understand speech information. It will have a low impact for other users.

Keys on the keypad that are discernible by touch: Tactile separators typically provide either raised or indented spaces between controls to assist in tactile differentiation of numeric keys from other keys. Inclusion in design will have a high impact for those who are blind, a medium impact for those with upper mobility impairments, and a low impact for all others. It will help resolve the issues of not being able to locate and identify controls and not being able to make accurate inputs.

Voiced menu options: Voiced menu options provide verbal output of the different menu screens, allowing the user to make appropriate inputs without having to see the display. This greatly increases the number of features that benefit a visually impaired user, in particular. Inclusion in design will have a high impact for those who are blind or have low vision, a medium impact for those with upper mobility impairments, and a low impact for all others. It will help resolve the issues of not being able to read text on the screen or to locate and identify controls.

Screen magnifiers: Screen magnifiers increase the size of the text on the display. Inclusion in the design will have a high impact for those who have low vision and a low impact for all other users. It will help resolve the issue of not being able to read text on the screen.

Larger keys on the keypad: Larger keys on the keypad increase the ability to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have poor fine motor control and a low impact for all other users. It will help resolve the issue of having difficulty making accurate inputs.

More space between keys on the keypad: More space between the keys increases the ability to differentiate the keys by touch and to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have an upper mobility impairment and a low impact for all other users. It will help resolve the issue of having difficulty locating controls and making accurate inputs.

Talking battery-level indicators: Talking battery-level indicators provide users who cannot see the screen with necessary information about the need to charge the phone. Inclusion in design will have a high impact for those who are blind and have low vision and a low impact for all other users. It will help resolve the issue of not being able to read the display.

Talking signal-strength indicators: Talking signal-strength indicators provide users who cannot see the screen with necessary information about the availability of coverage to successfully make and receive calls. Inclusion in design will have a high impact for those who are blind and have low vision and a low impact for all other users. It will help resolve the issue of not being able to read the display.

Talking caller-ID: Talking caller-ID provides users, particularly those with visual impairments, with information about an incoming call. Caller-ID allows users to identify the caller before answering the phone, permitting the user to decide not to answer without worrying about missing an important call. Inclusion in design will have a high impact for those who are blind or have low vision and a low impact for all other users. It will help resolve the issue of not being able to read text on the screen.

Large fonts on the display: Large fonts increase the text size on the display. Inclusion in design will have a high impact for those with low vision, a low impact for users who are blind, and a medium impact for all other users. It will help resolve the issue of not being able to read text on the screen.

Large display screens: Large display screens reduce screen clutter and increase the space available for larger text and graphics. Inclusion in design will have a medium impact for low vision users and a low impact for all others. It will help resolve the issue of not being able to read text on the screen.

Simplified connector for power: Simplified connectors for power allow the user to use a single hand with minimal pinching or grasping to connect the power cord to the device. Simplified connectors are not limited to insertion in a single orientation. Inclusion in design with have a medium impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users.

Simplified connector for headsets: Simplified connectors for headsets allow the user to use a single hand with minimal pinching or grasping to connect the headset cord to the device. Simplified connectors are not limited to insertion in a single orientation. Inclusion in design with have a medium impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users.

Hearing aid compatibility: Hearing aid compatibility includes both the ability for someone using a hearing aid to use the cell phone without interference and the ability to be in proximity of someone else using a cell phone without experiencing interference. Inclusion in design will have a high impact for users who are hard of hearing and a low impact for all others. Hearing aid compatibility will help resolve the issue of not being able to receive auditory information.

Concave keys on the keypads: Concave or inwardly curved keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. This type of key also increases the ability to differentiate the keys from each other and from the surrounding area on the device. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Concave keys will help resolve the issue of locating controls and making accurate inputs.

Keys that can be operated without human contact: Some individuals use pointing devices or other mechanisms to help them reach or activate controls. Some devices require moisture content or heat (characteristics of touch) to activate the controls; these devices cannot be used by someone who needs to use an alternative input device. Controls that are operable without physical human contact will have a high impact for someone with an upper mobility impairment and a low impact for all other users.

Rubberized keys: Rubberized keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. Textured keys also help the user differentiate the key itself from the surface of the device, particularly if the keys are not raised sufficiently. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Rubberized keys will help resolve the issues of locating controls and making accurate inputs.

Speakerphone: A speakerphone allows the user to carry on a conversation without needing to hold the phone. This is particularly useful for people who have upper mobility disabilities; if implemented in design, it will have a high impact. It will have a low impact for other users. A speakerphone will help resolve the issue of not being able to receive auditory information.

Additional features that may enhance accessibility are described in this discussion of an accessible phone: http://www.trace.wisc.edu/docs/phones/tcrd1/summary/index.htm. These features include:

Key shape: Keys can be shaped to be associated with their function. This can help someone relying on the tactile sense to better differentiate keys and may help those with cognitive disabilities to learn the appropriate use of various controls. Inclusion in design will have a high impact for people who are blind, a medium impact for people who have cognitive disabilities, and a low impact for all others.

Help request key: A help request key allows the user to press a designated key and then press another key to get information (verbal output), such as the status of a function or the function name for the selected key. Implementation in design will have a medium impact for those who are blind and a neutral impact for all other users. It will help resolve the issues of not being able to locate and identify controls or not being able to receive visual information.

Key confirmation: Key confirmation provides feedback about the selected option before activation of the control. It then requires the user to confirm the selection to implement activation. Key confirmation helps to prevent accidental activation, which is especially common for those who are blind or have upper mobility impairments. Implementation in design will have a medium impact for both of these groups and a neutral impact for others. (If key confirmation is not optional, it might have a negative impact for other users by slowing their transactions.) It will help resolve the issue of having difficulty locating controls and making accurate inputs.

Compliance with Government Regulations

The primary parts of section 508 that are applicable to cell phones address telecommunications (1194.23), self-contained closed products (1194.25), functional performance requirements (1194.31), and documentation (1194.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another.

The following section 508 regulations are seen as issues for cell phones:

• TTY compatibility.
• Verify that all controls and keys are tactilely discernible without activating the controls or keys. Many of the keys on cell phones do not have adequate tactile separators or a sufficient nib on the “5” key to facilitate tactile differentiation.
• The status of all locking or toggle controls or keys must be visually discernible and discernible either through touch or sound. The status of the phone when it is locked is available only visually.
• When products provide auditory output, the audio signal must be provided at a standard signal level through an industry standard connector that will allow for private listening. Some cell phones use proprietary connectors
• Verify that at least one mode of operation and information retrieval is provided that does not require user vision or, alternatively, that support is provided for assistive technology used by people who are blind or visually impaired. The majority of information is provided through a text display on the cell phone, which cannot be seen by a user who is blind
• At least one mode of operation and information retrieval that does not require visual acuity greater than 20/70 must be provided in audio and enlarged print output, working together or independently, or support for AT used by people who are visually impaired must be provided. Cell phones do not provide voice output, and they typically do not use more than a 10-point font, which is inadequate for someone with low vision.
• Where audio information is important for the use of a product, at least one mode of operation and information retrieval shall be provided in an enhanced auditory fashion, or support for assistive hearing devices must be provided. While many cell phones are designated as hearing aid compatible and loopsets are available for some phones, they do not work for all people with hearing aids. Some cell phones also provide insufficient volume control to assist those with hearing impairments.

Distance Learning Software

Distance learning is an excellent option for people with limited mobility or restricted schedules and those not near an educational provider. There are some human limitations, however, that make distance learning either inaccessible or difficult to use. People who have visual impairments may have difficulty accessing visual information and making accurate inputs. People who are deaf or hard of hearing may have difficulty accessing auditory information. People who have a mobility disability may have difficulty making accurate inputs and responding quickly enough to prompts. People who have cognitive disabilities may have difficulty understanding the language and responding quickly enough to prompts. Each of these challenges can be overcome, to some extent, through proper design (Tabs, 2003).

Streaming media are audio and video distributed in real time over the Internet. “Streaming” means the file can be viewed and heard before it is fully downloaded. An initial portion of the file is downloaded, or buffered, and begins playing, while the remainder of the file arrives in a continuous stream. Streaming media often refers not only to media distributed in real time, but to any media downloaded from the Internet.

In general, two sets of users will benefit most from streaming video that is accessible: people who are deaf or hard of hearing, and those who are blind or have low vision. People who are deaf or hard of hearing rely on captions to understand the audio content. People who are blind or have low vision rely on an audio description of the video content. However, as with all universal design, everyone benefits when streaming media is made accessible, even the provider of the streaming media. For example, captions can be made searchable, allowing for a much more elaborate video clip search and retrieval system. Captions also make streaming media more accessible for individuals who do not speak English, those for whom English is their second language, and those for whom printed English is more accessible than spoken English. Captions have also been shown to consistently improve reading retention of presented material.

Background

There are two main pieces of legislation that dictate accessibility of streaming media. The most obvious is the Americans with Disabilities Act of 1990, which requires that all public programs and services be accessible to people with disabilities. The second and most relevant piece of legislation is section 508, which was signed into law in August 1998 and became effective in June 2001. Section 508 requires that E&IT used by the Federal Government be accessible by people with disabilities and that accessibility must be comparable to that provided to the public without disabilities.

The provision of captioning for Internet video streams is still in its infancy when compared to the captioning of television programming. In some ways, captioning video streams is a more challenging problem because of the number of different video formats that must be considered. There is not at present any single, predominant standard for the captioning of Internet video streams. Several similar but distinct techniques are used; the techniques that are available depend on the format of the video stream. Three major formats are Apple’s Quicktime, Microsoft’s Windows Media, and Real’s RealPlayer. Each format has software bugs and some level of unreliability with respect to captioning.

Windows Media

Windows Media Player adds captions using Microsoft’s Synchronized Accessible Media Interchange (SAMI). SAMI is an extensible markup language (XML) based text language. SAMI files contain the actual captions, as well as information about when and how the captions should display. SAMI is structured very similarly to hypertext markup language (HTML), and many HTML formatting tags are allowed in SAMI. Broadly speaking, SAMI files consist of caption text with tags specifying the appearance of the text and time tags that control when each caption should be displayed (in terms of elapsed milliseconds from the start of the media file). SAMI files can be created in any text editor, though using a captioning program such as MAGpie to enter caption times simplifies the process.

There are two ways of adding captions to a media file. If the media file is embedded in a Web page (a practice that is not recommended for accessibility), code can be added to the Web page to display the captions along with the video. The recommended method involves creating a third file, called an active streaming XML (ASX) file. The ASX file is a pointer file that contains details about the media presentation and tells Windows Media Player which files (media and captions) to retrieve and play.

RealPlayer

RealPlayer uses the Synchronized Multimedia Integration Language (SMIL), developed by the World Wide Web Consortium (W3C), to choreograph the presentation of video and captions. SMIL is written as an XML application.

To caption a RealPlayer file, a RealText file containing caption text, timing, and formatting information is created. The RealText file can be created in any text editor, but using a captioning program such as MAGpie to enter caption times simplifies the process. Next, an SMIL file must be created that links the video (RealPlayer) file and the caption (RealText) file, and creates the screen regions in which the video and caption files will be played. Links to the SMIL files must be provided in the form of real audio movie (RAM) files. The link points to the RAM file, which in turn points to the SMIL file, which in turn points to the RealPlayer and RealText files. The video file can also be embedded in a Web page, but this practice is not recommended because of the accessibility problems it creates.

Quicktime

There are two methods for captioning Quicktime movies. The first involves creating a Quicktime text track and making it a part of the Quicktime movie. The result is a single file that contains audio, video, and captions. Quicktime Pro is required for this method. The second method involves creating a text track movie as a separate file, which is then synchronized with the movie with SMIL (as described above for RealPlayer).

In either case, a caption file must be created. This file can be created using any text editor or by using MAGpie. In the first method, Quicktime Pro is used to convert the caption file to a text track and merge it with the video file. In the second method, a separate SMIL file is created. There are a number of ways to access captioned Quicktime movies. If the captions are embedded in the movie, a direct link to the movie can be provided. Quicktime movies (or SMIL files) can be embedded into Web pages; this is an accessible option for Quicktime, because there is an option to make the control bar visible on the screen. Code can also be included in a Web page that will open a Quicktime movie or SMIL presentation in the Quicktime player.

Task-Based Accessibility Analysis

The core functionality considered to be necessary to effectively use distance learning programs consists of the following:

• Logging in to the system

• Navigating the system
• Obtaining content—text, auditory, visual (graphics, videos)
• Filling out forms
• Reading email messages
• Using Instant Messaging software
• Reading documents in Microsoft Word format
• Reading documents in Adobe PDF format
• Viewing presentations in Microsoft PowerPoint format
• Using chat software

Additional functionality that is typically inherent in distance learning design includes the following:

• Participating in audio or video conferencing

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, and the design of the system being used. Accessibility issues for each disability population were identified, along with an impact rating for each issue. The issues identified and the impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various distance learning providers’ marketing data produced features identified as accessible design components. Each of these components is listed, along with a description of the component and an assessment of the usefulness of the feature for disability groups. Some of these features may have been designed with a particular disability population in mind; others may have been designed simply as desirable features. In many cases, the accessibility features benefit or are used by a variety of people, and they may be considered to provide universal access. Each of the accessibility features listed below is a function of the distance learning software as well as the content developed by an administrative user of the software. Each of the features has the capability to be implemented in distance learning if the content developers include it in the course materials. Distance learning vendors provide guidance for course developers that addresses many of these issues.

Use of alt tags: Alt tags provided with images allow screen reader users to obtain information about the images that are present on the page. Without alt tags, a blind person using a screen reader may know only that an image is present but will have no idea what it represents. In addition, alt tags can be used as a means to ignore images that exist for aesthetic reasons and do not provide important information by providing blank or null alt text for the image, which simplifies the process of obtaining information through a screen reader. Implementation in design will have a high impact for those who are blind, a medium impact for those who have low vision, and a low impact for all others. It will help resolve the issue of being unable to receive important visual information, and in some cases, of having difficulty interpreting visual information.

Synchronized multimedia: Multimedia can consist of text, video, audio, and other content. Sometimes multiple sensory outputs are provided but not directly in parallel, which can be confusing for the individual performing multiple sensory processing. Multimedia should be synchronized with the material, or there should be linked multimedia files containing synchronized equivalent alternatives to assist those who may benefit from redundant information sources. Synchronized multimedia will have a medium impact on most users.

All information conveyed with color is also available without color: Color is a very good tool for grouping controls or identifying important information, as long as the viewer can see and differentiate color. Color provides a means to create contrast, code objects, and provide meaning without words. However, some people with visual impairments cannot benefit from the use of color, and the meaning may be lost to some people with cognitive disabilities. Therefore, while color is useful and should be used, it should not be the only means to differentiate objects, provide structure, or present useful information. Anything represented with color should also be available without color. Following this guideline in design will have a high impact for users who are blind or have low vision, a medium impact for users with cognitive difficulties, and a low impact for other users. Ensuring that no information is conveyed with color alone will help resolve the issues of not being able to receive important visual information and not being able to interpret some visual information.

Documents are organized so they are readable without requiring an associated style sheet: When documents require style sheets, individuals may not be able to control the appearance (font size, etc.) of the information on the page or to use their own customized style sheet. This may create problems for those who use screen readers. Implementing pages that are readable without style sheets will have a high impact for those with visual impairments. It will help resolve the issue of not being able to receive visual information.

Only client-side image maps are used (or, redundant text links are provided for each active region of a server-side image map): Client-side image maps make information available to people browsing with nongraphical user agents and offer immediate feedback as to whether or not the pointer is over an active region. Implementation of only client-side image maps in design will have a high impact for users who are blind and a medium impact for those with low vision. There will be a low impact for all other users. It will help resolve the issue of not being able to receive visual information.

Row and column headers are provided for data tables in order to take advantage of newer screen reader capabilities to process this additional information: Tables that are not constructed in an organized fashion with headers to describe the row and column contents are very difficult to interpret for someone relying on a screen reader. Headers can help the individual determine the organization of the information being presented. This facilitates navigation through the table and comprehension of the information contained in the table. Implementation in design will have a high impact for those who are blind, a medium impact for those who have low vision, and a neutral impact for all others. It will help resolve the issue of not being able to receive visual information.

Framesets are titled to facilitate identification and navigation: Frame titles let users know, for example, whether they are in the navigation frame or the content frame. Providing titles helps a person using a screen reader distinguish the organization of the information and facilitates navigation. Implementation in design will have a high impact for people who are blind and a low impact for all other users. It will help resolve the issue of not being able to receive visual information.

Pages are designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz: Some flicker frequencies can induce visual seizures. Flicker is most often an issue for animations, and pages should be designed so that only appropriate animations are used. Moving content can cause difficulty for people with low vision and cognitive disabilities, particularly if they must react at the same speed to click an object, for example. In addition, screen readers cannot read moving text. Implementation in design will have a high impact for those who are susceptible to visual seizures; a medium impact for those who have low vision, cognitive disabilities, or upper mobility impairments; and a low impact for other users. It will help resolve the issues of not being able to receive visual information, having difficulty interpreting visual information, and having difficulty making inputs, particularly when there is a time constraint.

Dynamic scripting is not used for content presentation: Dynamic scripting can be problematic for screen readers, sometimes providing an inaccurate description of the page content and preventing the user from receiving the same information that can be obtained visually. Implementation in design will have a high impact for users with no vision, a medium impact for users with low vision, and a neutral impact for other users. It will help resolve the issue of not being able to receive visual information.

Plug-ins are supported as embedded content or as automatically launched files: Some plug-ins that require interaction will only work with mouse input, which excludes a large number of users. Appropriately applied plug-ins implemented in design will have a high impact for those who are blind or have upper mobility impairments, a medium impact for those with low vision, and a neutral impact for the remainder of users. They will help resolve the issue of not being able to receive visual information and make appropriate inputs.

Form labels are placed next to the form input elements that are referenced, including input boxes and radio buttons: This allows screen reader users to appropriately associate labels with the form elements. A user should be able to fill out the form with either keyboard or mouse input. Implementation in design will have a high impact for those who have visual or cognitive disabilities and a low impact for all other users. It will help resolve the issues of not being able to receive visual information and of having difficulty interpreting visual information.

For navigation links located in the body of the main content page, code exists to allow screen readers to detect and skip the navigation links: When navigation links are in the main content page, they are read each time the page is accessed. This can be very time-consuming and unnecessary for someone using a screen reader to find or review a part of the page. Providing a means for the user to skip over the navigation links allows the user to read through the page and get to the needed information more easily and quickly. Implementation in design will have a high impact for those who are blind and a medium impact for those with low vision. It will help resolve the issue of not being able to receive visual information.

Session timeout settings can be modified by the system administrator to allow for more time, if necessary: Some systems require an input within a certain amount of time before they end the session; this provides security and helps free up access to others. However, some people cannot respond in appropriate time limits because they are using a screen reader, which takes longer than expected to process the page; they themselves are slow to process the page content; or they have difficulty with fine motor control and making appropriate inputs. If time-dependent settings can be controlled as needed for individuals, it will have a high impact for those who are blind or have cognitive disabilities or upper mobility impairments. It will help resolve the issues of not being able to receive visual information and having difficulty making inputs.

Online help documentation is provided describing layout, context, functionality of each feature, and instructions for using the features: Some systems may use functionality that is atypical or not intuitive, particularly for those who cannot visually explore the contents. Implementation of online help documentation will have a medium impact for those with visual or cognitive disabilities and a low impact for all other users.

Additional features we feel would make a distance learning program accessible include the following:

Screen reader compatibility: Screen readers allow users to obtain information without visually perceiving it. Visual information is translated into auditory output that is read to the user. The most common users of screen reading technology are those who are blind or have low vision. Implementation in design will have a high impact for those who are blind, a medium impact for those with low vision, and a neutral impact for all others. Screen reading compatibility will help resolve the issue of not being able to receive visual information.

Printed materials available in alternative formats: Alternative formats include large print, Braille, and audio. They mostly benefit users with visual impairments, providing a high impact for that user group. Distribution of documents in an accessible electronic format that is convertible is often preferred. It will help resolve the issue of not being able to receive visual information.

Uncluttered pages, pages that are well organized, and pages that don’t have backgrounds that interfere with processing foreground information: Pages with a lot of information, colors, patterns, and movement can be very difficult for some people to process. Avoiding these things in design will have a medium impact on those with low vision and cognitive disabilities. It will help resolve the issues of having difficulty receiving and interpreting visual information and having difficulty finding desired features.

Consistent layouts from page to page: Information that is organized in a similar fashion from one page to the next helps the user to quickly find items of interest. Implementation in design will have a medium impact for those who have a cognitive disability and a low impact for all other users. It will help resolve the issues of having difficulty receiving and interpreting visual information and having difficulty finding desired features.

Closed-captioned video: Videos, audio clips, and live presentations naturally have audio output, but they do not readily have comparable visual output available. Graphics and text to describe the audio information, particularly direct transcriptions, can greatly enhance the accessibility of this information for those with hearing impairments, having a high impact for this population of users. It will help resolve the issue of not being able to receive auditory information.

A text-only page, with equivalent information or functionality, should be provided when accessibility cannot be achieved in any other way: The content of the text-only page should be updated whenever the primary page changes. This will have a high impact for those who are blind, a medium impact for those with low vision, and a low impact for other users. It will help solve the issue of not being able to receive visual information.

User manuals in alternative formats: Alternative formats include large print, Braille, and audio. Inclusion in design will have a high positive impact for users who are blind or have low vision, possibly the same for those with hearing impairments (depending on the original format), and no impact for other disability populations. It will help resolve the issue of not being able to receive visual (and possibly auditory) information.

Screen magnifier compatibility: A screen magnifier increases the size of the display and button labels to enhance the readability for those with low vision. It is an alternative, particularly if adjustable screen resolution and font size are unavailable. Implementation in design will have a medium impact for those with low vision and a neutral impact for other users. It will help resolve the issues of not being able to receive visual information and not being able to locate and identify controls.

Adjustable font sizes: Small fonts are very difficult to read for users with low vision, who typically need to squint or use a magnifying glass to read them. They are also more difficult to read under low-light conditions and when users are fatigued. Implementation in design of adjustable font sizes will have a high impact on users with low vision and, with the exception of people who are blind, a low impact on all other users. It will help resolve the issue of not being able to receive visual information.

Adjustable contrast: Adjustable contrast provides the option for users to adjust the color or brightness of the foreground and background colors to increase clarity. Inclusion in design will have a high impact for those with low vision and most users under very bright- or low-light conditions. It will have a low impact for other disability populations. Adjustable contrast will help resolve the issue of not being able to receive visual information.

Graphics that are described in detail: Graphics may be impossible to see for a person who is blind, difficult to see and interpret for those who have low vision, and difficult to understand for those who do not learn well from pictures. Inclusion of detailed descriptions will have a high impact for those who are blind or have low vision, and a low to medium impact for all other users. Described graphics will help resolve the issue of not being able to receive visual information.

Video that is described in detail: Video may be impossible to see for a person who is blind and difficult to see for those who have low vision or are limited to small video screens with insufficient resolution. Inclusion of detailed descriptions will have a high impact for those who are blind or have low vision, and a low impact for all other users. Described video will help resolve the issue of not being able to receive visual information.

Adjustable volume: Volume control is important for auditory information and alerts. This is particularly important for hard-of-hearing people, but it is useful for all. Inclusion in design will have a medium impact for hard-of-hearing people and a low impact for all other users. It will help resolve the issue of not being able to receive auditory information.

Ability to request additional time: Ability to request additional time allows the user to be able to complete a transaction despite the need to use more than the normal amount of allotted time to complete individual transaction components. Inclusion in design will have a high impact for most users, depending on the output mode (visual or auditory) from the device. Additional time will help resolve the issues of not being able to receive visual or auditory information and having difficulty with control inputs.

Voice recognition: Voice recognition allows the user to provide inputs verbally rather than through mechanical keypresses. Voice recognition is particularly useful for those who cannot see to make the correct inputs or cannot reach or have difficulty activating mechanical controls. Implementation in design will have a high impact for those who are blind, a medium impact for those who have low vision or an upper mobility impairment, and a low impact for other users. It will help resolve the issues of having difficulty entering/inputting information, difficulty making accurate inputs, difficulty lifting and holding the device, and possibly difficulty finding desired features and interpreting visual information.

The primary parts of section 508 that are applicable to distance learning address software applications and operating systems (1194.21), Web-based Intranet and Internet information and applications (1194.22), video and multimedia products (1194.24), functional performance requirements (1191.31), and documentation (1191.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another.

The following section 508 regulations are seen as issues for distance learning:

• Sufficient information about a user interface element, including the identity, operation, and state of the element, must be available to assistive technology. When an image represents a program element, the information conveyed by the image must also be available in text. The creators of distance learning content do not always provide text equivalents for graphical information. Some features of the software interface are not recognized by screen readers.

• A text equivalent for every nontext element must be provided (e.g., via “alt,” “longdesc,” or in-element content). The creators of distance learning content do not always provide text equivalents for graphical information.

• Equivalent alternatives for any multimedia presentation must be synchronized with the presentation. Equivalent alternatives are often not provided and are typically not synched when they are available.

• At least one mode of operation and information retrieval must be provided that does not require user vision or, alternatively, that support for assistive technology used by people who are blind or visually impaired is provided. Much content is provided in a graphical fashion that cannot be seen by those with visual limitations and that cannot be read by a screen reader.

• At least one mode of operation and information retrieval that does not require user hearing must be provided, or support for AT used by people who are deaf or hard of hearing must be provided. Distance learning content is often provided in an auditory fashion without closed-captioning or text to accompany the output.

Personal Digital Assistants

Despite their popularity and their capabilities, PDAs are not accessible to everyone. There are some human limitations that make PDAs either inaccessible or difficult to use (and therefore perhaps undesirable). People who have visual impairments may have difficulty accessing visual information and providing accurate inputs. People who are deaf or hard of hearing may have difficulty detecting auditory alerts. People who have a mobility disability may have difficulty simultaneously handling the PDA and manipulating the controls. People who have cognitive disabilities may have difficulty understanding metaphors and jargon and remembering how to access information. Each of these challenges can be overcome, to some extent, through proper design.

Background

Personal digital assistants are popular for both personal and business use. There are thousands of applications available for PDAs, many of them free, that support a wide range of activities. PDAs have the potential to provide benefits to individuals with disabilities, but they are not currently accessible to all users. Users generally interact with PDAs by use of a small stylus for input and a small screen for output, producing barriers for users with visual or mobility impairments in particular.

Text Input and Output

To assist people who are unable to use the stylus, nearly all PDAs support the attachment of various types of keyboards, including those that support one-handed typing such as the halfkeyboard.

The AlphaPad is a software application for PalmOS and Window CE that uses a 12-key keyboard along with word prediction software. The keyboard is displayed on a touchscreen, so fine motor control is necessary, but it could be useful for low-mobility users. Thumbscript is another text-entry system that uses gestures on a nine-button grid to produce characters. It is compatible with any device having eight actuation points arranged radially around a center and may be useful for users with mobility impairments. There are a number of other variations on stylus-based text entry, as well.

Several products provide some degree of voice interaction with PDAs. IBM has released a version of its ViaVoice application for Pocket PCs. This application serves as a text-to-speech screen reader and also allows user input utilizing a limited command vocabulary. ScanSoft’s Dragon PDsay provides similar functionality for Pocket PCs. Both of these products are command-based and don’t support dictation or application-specific functionality beyond a basic core set of popular applications.

Display Features

TealMagnify is a screen magnifier for PalmOS that may be of use to people with visual impairments, although it requires users to touch a button on the PDA to activate it and apparently produces rather pixilated results.

For users with low vision, many PDAs are now available with bright color displays. Palm claims that some (but not all) of its color models provide a variety of color and contrast adjustments for users with visual impairments, and there are a number of third-party applications that allow customization of display colors. Pocket PCs apparently can also be modified to provide a higher contrast color scheme.

PDAs Designed Specifically for Users with Disabilities

Enkidu makes a line of portable communication devices known as the IMPACT family that is designed specifically for users with various disabilities. These devices provide speech output and support input via touchscreen, integrated buttons, keyboard, or external switches.

Task-Based Accessibility Analysis

The core functionality considered to be necessary to effectively use a PDA consists of the following:

• Locating the PDA
• Turning the PDA on and off

• Storing an appointment

• Recalling an appointment

• Viewing the calendar
• Using the calculator
• Making and retrieving a memo or notes
• Storing contact information
• Recalling contact information
• Reading/composing/sending email
• Making and retrieving a TO DO list entry
• Syncing with a computer
• Adjusting screen contrast
• Adjusting font sizes
• Receiving an alert
• Detecting battery status
• Charging or replacing batteries

• Installing software

Additional functionality that is typically inherent in PDA design includes the following:

• Tracking expenses

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, and the design of the PDA. Accessibility issues for each disability population were identified (taken in part from www.techdis.ac.uk/PDA/front.htm), along with an impact rating for each issue. The disability populations include people who have an impairment resulting from environmental or situational factors. The issues identified and the impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various PDA manufacturers’ marketing data produced few features identified as accessible design components. Each accessibility feature is listed, along with its description, a determination of availability in the product line, and an assessment of whether the feature actually improves accessibility.

Screen reader compatibility: Screen readers allow users to obtain information without the need to perceive it visually. Visual information is translated into auditory output that is read to the user. The most common users of screen reading technology are people who are blind or have low vision. Implementation in design will have a high impact for these groups and a neutral impact for other groups. It will help resolve the issue of not being able to receive visual information. Jaws and other screen readers are not available for mainstream PDAs. ViaVoice is available, but it is designed more for voice input than output, and output is very limited. ViaVoice provides some options for a person who is blind trying to use a PDA, but it is not a substitute for a screen reader.

Additional features that would make a PDA accessible include the following (taken in part from www.techdis.ac.uk/PDA/front.htm):

Adjustable display resolution: Display resolution affects the quality of the visual images provided as well as the amount of information that can be seen at a single time. Someone with low vision, for example, may need a lower display resolution, which increases the size of the images, in order to clearly interpret the information provided. Thus, allowing the display resolution to be adjusted enhances the accessibility for various individuals. If implemented in design, it will have a high impact on those with low vision and, with the exception of people who are blind, a medium impact on other users. It will help resolve the issue of not being able to receive visual information.

Adjustable font size: Small fonts are very difficult to read for users with low vision, who typically need to squint or use a magnifying glass to read them. They are also more difficult to read under low-light conditions and when users are fatigued. Implementation in design of adjustable font sizes will have a high impact on users with low vision and, with the exception of people who are blind, a low impact on all other users. It will help resolve the issue of not being able to receive visual information.

Adjustable contrast control: Adjustable contrast provides the option for users to adjust the color or brightness of the foreground and background shades to increase clarity. Ease of contrast adjustment, for example, through a hardware control, greatly improves the accessibility for many individuals, but it could mean the difference between being able to use the PDA and not for a low-vision user. Inclusion in design will have a high impact for those with low vision and most users under very bright- or low-light conditions. It will have a low impact for other disability populations. Adjustable contrast will help resolve the issue of not being able to receive visual information.

Ability to adjust screen colors: Adjustable color provides the option for users to adjust the color or brightness of the foreground and background colors to increase clarity. Inclusion in design will have a high impact for those with low vision and for most users under very bright- or low-light conditions. It will have a low impact for other disability populations. Adjustable color will help resolve the issue of not being able to receive visual information.

Good screen lighting: Adjustable screen lighting accommodates low-light conditions. This is useful for all individuals in some contexts and can also be useful for users with low vision in a wider variety of conditions. Inclusion in design will have a medium impact for users with low vision and a low impact for all other users. It will help resolve the issue of not being able to receive visual information.

Buttons with good tactile quality: Buttons that have texture and are not slick are easier to distinguish by feel and to use without slipping and accidentally activating an adjacent control. Implementation in design will have a medium impact on those who are blind and those with upper mobility impairments. It will help resolve the issues of having difficulty locating and identifying controls and difficulty making accurate inputs.

Adequately sized button labels and symbols: Users with low vision may have difficulty reading small labels or interpreting small symbols, particularly under low-light conditions. Implementation in design of adequately sized text and graphics on buttons will have a high impact on users with low vision and, with the exception of people who are blind, a low impact on all other users. It will help resolve the issues of not being able to receive visual information and not being able to locate and identify controls.

Voice recognition: Voice recognition provides the option to provide inputs verbally rather than through mechanical keypresses. This is particularly useful for those who cannot see to make the correct inputs or cannot reach or have difficulty activating mechanical controls. Implementation in design will have a high impact for those who are blind, a medium impact for those who have low vision or an upper mobility impairment, and a low impact for other users. It will help resolve the issues of having difficulty entering/inputting information, difficulty making accurate inputs, difficulty lifting and holding the device, and possibly the difficulties of finding desired features and interpreting visual information.

Screen magnifier compatibility: An external screen magnifier increases the size of the display and button labels to enhance the readability for those with low vision. It is an alternative, particularly if adjustable display resolution and font size are unavailable. Implementation in design will have a medium impact for those with low vision and a neutral impact for other users. It will help resolve the issues of not being able to receive visual information and not being able to locate and identify controls.

Good use of visual metaphors; simple graphical navigational aids: Graphics are very useful for people who have difficulty reading text. Graphics can help declutter a display by reducing the need for text. Implementation in design will have a high impact on the cognitively disabled, a medium impact for those with low vision, a neutral impact for people who are blind, and a low impact for all other users. It will help resolve the issues of not being able to receive or understand visual information and not being able to find desired features.

Clear menu structures: Simple menus and information organization help all users find the information they are looking for in a timely fashion. They require fewer inputs, which can be very beneficial for those who have trouble finding or manipulating controls. Implementation in design will have a high impact for all users. It will help resolve the issues of not being able to receive or understand visual information and not being able to find desired features.

Auditory, visual, and vibrating alerts: Alerts provided in a redundant fashion assist users with specific physical impairments as well as those who encounter a situation in which the normal alerting mode is insufficient. Implementation in design will have a high impact for users who are visually or hearing impaired and a medium impact for all other users. It will help resolve the issue of not being able to receive visual or auditory information.

Use of simple language (not PDA-specific technical jargon): Some individuals may have difficulty using a device simply because they do not understand the terms that are used to refer to various features. Implementation of simple language will have a high impact on users who have a cognitive disability and a medium impact on all other users. It will help resolve the issues of not being able to respond in the allotted period of time or not being able to interpret visual information.

Minimal force requirement for activating controls: The effort required to activate a control may be more than an individual can provide, preventing that individual from using the device. Implementation of minimal force will have a high impact for users with upper mobility impairments and a low impact for all other users. It will help resolve the issue of not being able to make inputs.

Input alternatives other than stylus and touchscreen controls (e.g., keyboard): Users who cannot see or who have difficulty controlling certain input devices benefit from having an alternative input mechanism. Implementation in design will have a high impact for users who are blind, have low vision, or have an upper mobility impairment. It will have a low impact for all other users. It will help resolve the issue of not being able to provide inputs.

Choice of stylus size and style: A stylus is typically a very thin, smooth-surfaced pointing device, which can be difficult for some individuals to hold onto. Implementation of choice of styli will have a high impact on those with upper mobility impairments and a neutral impact on all other users. It will help resolve the issue of not being able to make accurate inputs.

PDA cases designed with materials that increase friction and grip: A PDA case typically houses the PDA device, even while in use. The case adds to the size and potentially awkward shape of the device, which can be cumbersome for some users. Implementation of friction in design will provide a medium impact for users with upper mobility impairments and a neutral impact for all other users. It will help resolve the issue of not being able to lift and hold the device.

An overall shape and size (weight) that allows the device to be comfortably held in the average adult hand: The shape and size of a PDA can affect the ability to hold the device and, specifically, to hold and manipulate the device simultaneously. A lightweight contoured shape will have a high medium impact on users with upper mobility impairments and a low impact on all other users. It will help resolve the issue of not being able to lift and hold the device.

The availability or feasibility of mounting brackets for use with a desk or wheelchair or in a fixed location: A mobile holder is a mounting mechanism that can be attached to a wheelchair or other mobility aid or installed in a car to provide a consistent, secure place to store the PDA. When using a PDA, people often hold the device with one hand and make inputs with the other. This is problematic for people who may be unable to hold and manipulate the device simultaneously. However, if the device were constructed so it could be secured to another surface to handle the “holding component” of using the PDA, it would increase the accessibility for those with an upper mobility impairment. If implemented in design, this feature will have a high impact for those with upper mobility impairments and a low impact for other groups. It will help resolve the issue of not being able to lift and hold the device.

Adjustable zoom: A zoom display provides the option to increase the text size predefined amounts, reducing the number of lines of text available at any given time. Inclusion in design will have a medium impact for users with low vision and a low impact for others. It will help resolve the issue of not being able to receive visual information.

Availability of user-defined alerts: Auditory alerts sometimes accompany visual alerts, which can help differentiate one from another. For those who cannot see, however, or for people who are hard of hearing, a way to make the alerts more distinct and meaningful for will increase the user’s ability to process and make use of the auditory alerts by themselves. Implementation in design will have a high impact for those who are hard of hearing or have visual impairments and a low impact for all other users. It will help resolve the issues of not being able to receive visual information and difficulty receiving auditory information.

User manuals in alternative formats: Alternative formats include large print, Braille, and audio. Inclusion in design will have a high impact for users who are blind or have low vision, a medium impact for users with upper mobility impairments, and no impact for other disability populations. It will help resolve the issues of not being able to read or handle printed materials.

Large fonts on the display: Large fonts on the display increase the text size for circumstances in which small text is difficult to read. Inclusion in design will have a high impact for those with low vision, a low impact for users who are blind, and a medium impact for all other users. It will help resolve the issue of not being able to read text on the screen.

Large display screens: Large display screens reduce screen clutter and increase the space available for larger text and graphics. Inclusion in design will have a medium impact for low vision and cognitively disabled users and a low impact for all others. It will help resolve the issue of not being able to read text on the screen.

High-contrast displays: High contrast provides the option for users to adjust the color or brightness of the foreground and background colors so that the text stands out from the background, increasing readability. Inclusion in design will have a high impact for those with low vision and most users under very bright- or low-light conditions. It will have a low impact for other disability populations. High contrast will help resolve the issue of not being able to receive visual information.

Large keys: Large keys on the keypad increase the ability to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have poor fine motor control, and a low impact for all other users. It will help resolve the issue of having difficulty making accurate inputs.

More space between keys: More space between the keys increases the ability to differentiate the keys by touch and to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. It will help resolve the issue of having difficulty locating controls and making accurate inputs.

Keys that are discernible by touch: Tactile separators typically provide either raised or indented spaces between controls to assist in tactile differentiation of numeric keys from other keys. Inclusion in design will have a high impact for those who are blind, a medium impact for those with upper mobility impairments, and a low impact for all others. It will help resolve the issues of not being able to locate and identify controls and not being able to make accurate inputs.

Simplified connector for power: A simplified power connector allows the user to use a single hand with minimal pinching or grasping to connect the power cord to the device. Simplified connectors are not limited to insertion in a single orientation. Inclusion in design will have a medium impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users.

Simplified connector for headsets: A simplified headset connector allows the user to connect the headset cord to the device with a single hand with minimal pinching or grasping. Simplified connectors are not limited to insertion in a single orientation. Inclusion in design will have a medium impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users.

Adjustable timeouts: Adjustable timeouts allow the individual to set the amount of time for features that have timeout settings. This accommodates those who may be slower in making inputs or who prefer to minimize the number of inputs, which may increase when a setting times out. Inclusion in design will have a medium impact for those who are blind, have low vision, or have upper mobility impairments. Adjustable timeouts will help resolve the issues of not being able to receive visual information or to respond within an allotted period of time.

Ability to request additional time: Ability to request additional time allows the user to complete a transaction despite the need to use more than the normal amount of allotted time to complete individual transaction components. Inclusion in design will have a high impact for most users, depending on the output mode (visual or auditory) from the device. Additional time will help resolve the issues of not being able to receive visual or auditory information, not being able to reach controls, and not being able to grasp objects.

Adjustable volume: Volume control is important for auditory alerts. It is particularly important for hard-of-hearing people, but it is useful for all. Inclusion in design will have a medium impact for hard-of-hearing people and a low impact for all other users. It will help resolve the issue of not being able to receive auditory information.

Concave keys on the keypads: Concave or inwardly curved keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. This type of key also increases the ability to differentiate the keys from each other and from the surrounding area on the device. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Concave keys will help resolve the issue of locating controls and making accurate inputs.

Keys that can be operated without human contact: Some individuals use pointing devices or other mechanisms to help them reach or activate controls. Some devices require moisture content or heat to activate the controls; these devices cannot be used by someone who needs to use an alternative input device. Controls that are operable without physical human contact will have a high impact for someone with an upper mobility impairment and a low impact for all other users.

Rubberized keys: Rubberized keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. Textured keys also help the user differentiate the key itself from the surface of the device, particularly if the keys are not raised sufficiently. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Rubberized keys will help resolve the issue of locating controls and making accurate inputs.

Compliance with Government Regulations

The primary parts of section 508 that are applicable to PDAs address self-contained closed products (1194.25), functional performance requirements (1191.31), and documentation (1191.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another.

The following section 508 regulations are seen as issues for PDAs:

• Verify that all controls and keys are tactilely discernible without activating the controls or keys. Since the PDA system is primarily touchscreen-based, it is not possible to have tactilely discernible controls unless they are redundant with hardware controls.

• Verify that this self-contained product is usable by people with disabilities, without requiring the end-user to attach assistive technology to the product. There is very little a user who is blind can accomplish with a PDA without the assistance of voice output. Unfortunately, screen reader software is not yet available for a PDA.

• Verify that at least one mode of operation and information retrieval is provided that does not require user vision or, alternatively, that support for AT used by people who are blind or visually impaired is provided. As indicated above, there is very little a user who is blind can accomplish with a PDA without the assistance of voice output. Unfortunately, screen reader software is not yet available for a PDA.

• Provide at least one mode of operation and information retrieval that does not require visual acuity greater than 20/70 in audio and enlarged print output, working together or independently, or provide support for AT used by people who are visually impaired. PDAs do not provide voice output, and they typically do not use more than a 10- or 12-point font, which is inadequate for someone with low vision. Increased font size is available only for a limited application set.

Televisions

There are some human limitations that make TVs either inaccessible or difficult to use. People who have visual impairments may have difficulty perceiving visual information and providing accurate inputs. People who are deaf or hard of hearing may have difficulty perceiving auditory information. People who have a mobility disability may have difficulty activating controls. People who have cognitive disabilities may have difficulty understanding control options.

Background

Television is the medium that entertains, informs, and educates; it can also serve as a companion to people who, because of circumstances beyond their control, are confined to their homes. Traditionally, people have used TV to get news reports and watch movies, sports events, and sitcoms. However, televisions are not currently accessible to all users. Certain services have become available to make television more accessible to users with disabilities. Closed-captioning and real-time captioning for live broadcasts have made televisions more accessible to users with hearing impairments by allowing them to understand the auditory portion of television programs. Descriptive video services have increased accessibility for users with visual impairments by allowing them to better understand the visual portion of television programs. New challenges to accessibility have been posed with the rise of digital television and interactive services, but accessible design solutions have been proposed to overcome the barriers associated with this new technology.

Closed-Captioning

In 1970, the National Bureau of Standards began investigating the possibility of using a portion of the network television signal to broadcast time information in a part of the signal not used for picture information. The American Broadcasting Company (ABC) network took part in this project; and although the project didn’t work, ABC suggested that it might be possible to send captions in the unused bandwidth.

In 1971, two captioning technologies were demonstrated at the First National Conference on Television for the Hearing Impaired. A second demonstration was held at Gallaudet College on February 15, 1972. In the second demonstration, ABC presented closed-captions embedded in the normal broadcast of The Mod Squad. The Federal Government agreed to fund the development and testing of captioning.

In 1973, engineers at the Public Broadcasting System (PBS) started working on the project under contract to the Bureau of Education for the Handicapped of the Department of Health, Education, and Welfare. The closed-captioning system was successfully tested that year in Washington, D.C., with the captions being broadcast using Line 21 of the vertical blanking interval. In 1976, the FCC set aside Line 21 for the transmission of closed-captions in the United States.

The first closed-captioned television series was broadcast on March 16, 1980. In 1982, the National Captioning Institute (NCI) developed real-time captioning for use in newscasts, sports events, and other live broadcasts.

NCI partnered with the ITT Corporation in the late 1980s to develop the first caption-decoding microchip that could be built directly into new television sets in 1989. In 1990, the Television Decoder Circuitry Act was passed. This Act mandated that, by mid-1993, all new television sets 13 inches or larger manufactured for sale in the United States must contain caption-decoding technology.

Also in 1990, the Americans with Disabilities Act was passed. Title III of the ADA requires that public facilities, such as hospitals, bars, shopping centers, and museums (but not movie theaters), provide access to verbal information on televisions, films, or slide shows. (Captioning is considered one way of making this information available.) Federally funded public service announcements must also be captioned.

To implement the closed-captioning requirements of the Telecommunications Act of 1996, the FCC established rules and implementation schedules for the captioning of television programming. These rules went into effect on January 1, 1998, and established an eight-year transition period for new programming. (At the end of the transition period, 100 percent of nonexempt new programs must be captioned.) A similar schedule was established for the captioning of Spanish-language programming.

Section 508 of the Rehabilitation Act, as strengthened by the Workforce Investment Act of 1998, requires that federal agencies make their E&IT accessible to people with disabilities, including employees and the general public. The requirements of section 508 apply to an agency’s procurement of E&IT, as well as to the agency’s development, maintenance, or use of E&IT. All training and informational video and multimedia productions that support the agency’s mission, regardless of format, must be open- or closed-captioned if they contain speech or other audio information necessary for the comprehension of the content. All training and informational video and multimedia productions that support the agency’s mission, regardless of format, must include an audible description of the video content if they contain visual information necessary for the comprehension of the content.

By 1998, new standards for captioning in high definition television (HDTV) were being created. These new standards greatly expanded the capabilities of captioning for HDTV, including—

• Variable-size captions

• Multiple fonts and colors

• Different font and background styles

• More information bandwidth

• A larger symbol set

In addition to the obvious benefits to deaf and hard-of-hearing persons, captioned television is a valuable tool for young children who are learning to read, illiterate adults who are learning to read, children and adults with learning disabilities, people in public places, and people learning English as a second language.

Descriptive Video Service

Descriptive video information or descriptive video service (DVS) enables visually impaired people to better understand the visual portions of television programs. A TV program with DVS has an additional audio track with a narrator describing the setting, what actions are taking place, who is talking, and any other important information that a visually impaired person would not be able to see. The narration is timed so that the narration does not interfere with dialog.

The roots of DVS date back to the 1960s, when some attempts were made to fill in the gaps for Star Trek episodes through audio cassettes. In the 1970s, a former radio broadcaster began describing movies on a radio station in Philadelphia. In 1981, Margaret Pfanstiehl began describing live theatrical performances in Washington, D.C., and later developed descriptive techniques and described some programs that were broadcast over the radio reading service.

In 1985, stereo television broadcasting began. WGBH, a Boston public television station, began exploring possible ways to use the secondary audio program (SAP) audio channel to carry narrated descriptions of a program’s key visual elements. The goal was to eliminate the need for a specially developed assistive device in order to receive the descriptions.

In 1988, the Corporation for Public Broadcasting awarded WGBH a grant to develop a complete business and operational plan for the permanent establishment of DVS. At the same time, WGBH funded all aspects of a national test of the service that was conducted in conjunction with PBS and other groups.

In 2000, spurred by the major networks’ failure to voluntarily offer DVS, the FCC mandated the provision of DVS by broadcasters; but various groups (including the National Association of Broadcasters, the Motion Picture Association of America, and the National Cable and Telecommunications Association) challenged the mandate in court. They claimed that the FCC exceeded its authority and, by compelling speech, violated the First Amendment. The core of the issue appeared to be one of cost.

Under the FCC measure, network affiliates would have to offer four hours a week of prime time or children’s shows by June 2002; cable and satellite operators would have a similar requirement for top networks. Certain programming, including live news, sports, and talk shows, would be exempt.

There were a number of legal decisions between 2000 and 2002, with courts variously upholding and overturning the FCC mandate. In mid-June 2003, Senator John McCain introduced a bill (S. 1264, FCC Reauthorization Act of 2003) that would reinstate the FCC mandate. The bill was approved by the Senate Committee on Commerce, Science, and Transportation and is now awaiting approval by the full Senate. There is no House bill as of this printing.

The application of DVS is still somewhat limited compared to closed-captioning, consisting mainly of programming on PBS and a few other networks. Certain movies for which descriptions have been developed are available by direct mail, in libraries, and in video rental stores.

Real-Time Captioning

In 1982, NCI developed real-time captioning, a process for captioning newscasts, sports events, specials, and other live broadcasts as the events are being televised. In real-time captioning, court reporters who have been trained as real-time captioners type at speeds in excess of 225 words per minute to give viewers instantaneous access to live information. The viewer sees the captions within two to three seconds of the words being spoken, with the delay resulting from the time it takes the captioner to hear the words spoken and then key the words, and for the captions to be encoded.

Real-time captioners write what they hear phonetically, using a stenotype machine (also known as a shorthand machine), which has only 24 keys and a number bar. The basic concept behind machine shorthand is phonetic, where combinations of keys represent sounds, but the theory is much more complex than straight phonics. Multiple keys can be depressed simultaneously on steno machines to create different word combinations. No two captioners write exactly the same way, so each has a custom dictionary (typically containing 50,000 to 100,000 entries) composed of the phonetics and their corresponding English that the captioner uses to build words and create punctuation. The steno then goes into a computer system, where it is translated into text and commands. The captioning software on the computer formats the stream of text into captions and sends them to a caption encoder.

Accessibility of Digital Television and Interactive Services

Interacting with a modern television set, even for an action as basic as selecting a program, has become far more complex with the advent of digital television. The digital set-top boxes (STBs) used to access digital programming offer access to a large amount of information, entertainment, and services via electronic program guides (EPGs), which require users to scroll through lots of on-screen text and graphics to select programs or access advanced features such as parental controls and advance scheduling. The highly visual nature of this style of interface has created serious barriers for consumers who are blind or have low vision.

These barriers are similar in nature to those that were created by graphical user interfaces for computer operating systems and by the rise of the World Wide Web. Over time, screen readers and other technologies emerged to provide access to these environments, but so far those solutions have not been applied to STBs for digital television. The automatic conversion of EPGs to synthesized speech has proven problematic.

In February 2001, the National Center for Accessible Media (NCAM) at Boston public broadcasting station WGBH partnered with America Online to explore ways to make interactive TV accessible to audiences who are blind or visually impaired, focusing initially on making the EPG more accessible. The assumption was that the majority of the solutions required to make the EPG accessible will also apply to making other content accessible with the STB. Funding for the research was provided by the National Institute on Disability and Rehabilitation Research.

In August 2003, NCAM published A Developer’s Guide to Creating Talking Menus for Set-top Boxes and DVDs (NCAM, 2003). This document discusses the accessibility problems posed by the EPG and presents possible technological solutions to the problems and guidelines for content development.

According to the Guide, there are challenges in finding the best strategy for translating on-screen visual information into a spoken equivalent, and there are also technological challenges in actually delivering the spoken information. The primary technological challenges result from the operating constraints of current STB hardware. The computers inside American STBs are too primitive to support the additional capability needed to provide voice output.

The Guide states that speech synthesis is a far more feasible solution than the use of prerecorded speech, because the number of audio samples that would be required in the latter case would be unworkable. A system could be designed where the synthesized speech is provided from a central server along with the current program guide information, but the bandwidth and storage requirements of this approach make it unfeasible. The STB itself could perform the speech synthesis, which is a trivial task for most modern computers, but until the computing power of STBs catches up with that of desktop systems, this approach is not possible.

Some other alternatives include using a more powerful third-party STB—such as a TiVO or other personal digital recorder—to do the speech synthesis, or to dispense with the STB altogether and route the cable signal through a desktop computer.

For users with low vision and/or other disabilities, the ability to adjust various aspects of the display (such as font sizes and text/background contrast settings) would be beneficial. In the article “Interactive Digital Television Services for People with Low Vision,” Sylvie Perera (n.d.) advocates the use of a smart card identification system to allow low-vision users to set personal preferences for such features as text size, content layout, speech output, audio description, color combinations, timeouts, reminders, and alerts. This scheme could also be extended to assist users with other disabilities by allowing the smart card preferences to include subtitles, signing, and other features.

Task-Based Accessibility Analysis

The core functionality considered to be necessary to effectively use a TV consists of the following:

• Turning the TV on and off
• Changing the input source

• Changing the channel

• Adjusting the volume
• Activating closed-captioning (CC)

• Accessing the EPG
• Activating DVS

• Adjusting picture quality settings
• Using picture-in-picture (PIP) features

Additional functionality that is typically inherent in TV design includes the following:

• Setting the time
• Automatically or manually adding/deleting channels
• Setting the TV to turn on and off automatically

In many cases, these functions require or are facilitated by use of the remote control.

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, and the design of the TV. Accessibility issues for each disability population were identified, along with an impact rating for each issue. The disability populations include people who have an impairment resulting from environmental or situational factors. The issues identified and the impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various TV manufacturers’ marketing data produced a single feature identified as an accessible design component. This component is listed, along with a description of the component and an assessment of the usefulness of the feature for disability groups. While this feature was designed with a particular disability population in mind, it turns out that it benefits and has been used by a much wider variety of people than anticipated and may be considered a universal design feature.

Closed-captioning: Information can be obtained from TV both visually and auditorily, but the visual information is very limited for something like a news show, for example, which inhibits hearing-impaired people from benefiting from the TV as an information source. The Television Decoder Circuitry Act of 1990 requires decoder chips in U.S. TVs; as of 1993, all 13-inch or larger TVs were required to have decoder circuitry built in to provide CC. A phase-in is under way to make CC available for all TV programming. In addition to helping people who are deaf or hard of hearing, CC benefits those whose native language differs from the programming language and children or others who are learning to read (http://www.fcc.gov/cgb/consumerfacts/closedcaption.html). CC has greatly enhanced the accessibility of TV for people who are deaf or hard of hearing, having a high impact if implemented in design, and serves as a useful feature with low impact for the population as a whole. It helps resolve the issue of not being able to receive auditory information.

Additional features that would make a TV more accessible include the following:

Selection of SAP via a dedicated button on the remote control: SAP is an often-used feature, most commonly used for translation of English programming into Spanish or, less commonly, to provide sign language interpretation. Access to this programming option is often nonintuitive and cannot be done quickly. Access through a dedicated remote control button would greatly enhance accessibility for those challenged by sound or cognition, having a medium impact for these groups if implemented in design and a neutral impact for other users. It will help resolve the issue of not being able to interpret auditory or visual information.

Selection of DVS via a dedicated button on the remote control: Access to DVS is typically through a menu structure that is often nonintuitive and cannot be done quickly. Access through a dedicated remote control button would greatly enhance accessibility for those who are blind or have low vision, having a high impact for these groups if implemented in design and a neutral impact for other users. It will help resolve the issue of not being able to interpret visual information.

Selection of CC via a dedicated button on the remote control: Access to CC is typically through a menu structure that is often nonintuitive and cannot be done quickly. Access through a dedicated remote control button would greatly enhance accessibility for those challenged by sound, having a medium impact for this group if implemented in design and a neutral impact for other users. It will help resolve the issue of not being able to interpret auditory information.

Vivid picture for clarity of CC: CC is typically provided in all capital letters, which is harder to read than mixed capital and lowercase letters. In addition, the readability varies with the quality of the television on which it is viewed. For example, HDTV sets offer a higher resolution image and typically greater clarity of CC material. Good picture quality can greatly enhance accessibility of information provided textually. Implementation in design will have a high impact for those with visual and hearing impairments and a low impact for all others. It will help resolve the issues of not being able to receive auditory and visual information.

High-quality audio system: For those people who depend on the auditory output of the TV to obtain information, quality of audio output can have a large impact on ability to accurately perceive information, especially for those who have a visual disability and cannot benefit from the redundancy provided by the images. Implementation in design will have a high impact for those who are hard of hearing and a medium impact for all other users, with the exception of those who are deaf. It will help resolve the issue of having difficulty receiving auditory information.

User manuals in alternative formats: Alternative formats include large print, Braille, and audio. Accessible electronic formats are also often acceptable. Inclusion in design will have a high impact for users who are blind or have low vision and a neutral impact for other disability populations. It will help resolve the issues of being unable to read or handle printed materials.

Voice-activated remote controls: A voice-activated remote control will allow the user to provide all inputs via voice rather than through mechanical key presses. If implemented in design, this will have a high impact for people who are blind and those with upper mobility impairments, a medium impact for those with low vision, and a neutral impact for other users. It will help resolve the issues of not being able to locate or identify controls, not being able to lift and hold the remote control, and not being able to make accurate inputs, and it may help with not being able to find desired features or respond within the allotted time.

Talking remote controls: A talking remote control is one with voice displays. Talking remote controls are useful in circumstances in which it is difficult to make control inputs or read the text display because of a visual impairment, significant glare on the screen, or possibly having to view the screen from a seated position. Inclusion in design will have a high impact for those who are blind, a medium impact for those with low vision, and a low impact for all other users. It will help resolve the issue of receiving and interpreting visual information.

Large buttons on the remote: Large keys on the keypad increase the ability to accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have poor fine motor control, and a low impact for all other users. It will help resolve the issue of having difficulty making accurate inputs.

More space between keys on the remote: More space between the keys increases the ability to differentiate the keys by touch and accurately press the desired key without inadvertently pressing any adjacent keys. Inclusion in design will have a medium impact for those who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. It will help resolve the issue of having difficulty locating controls and making accurate inputs.

DVS: DVS provides auditory output of key visual elements in visual programming. Inclusion in design will have a high impact for those who are blind or have low vision and a low impact for all other users. It will help resolve the issue of not being able to receive visual information.

Voiced on-screen menus: Voiced on-screen menus provide verbal output of the visual displays from the TV, allowing a user to become familiar with the menus without having to see them. On-screen menus are used for functions such as controlling TV features (such as CC or DVS) and setting up a VCR to tape a program. Inclusion in design of voiced menus will have a high impact for those who are blind or have low vision and a low impact for all other users. Voiced menus help resolve the issue of not being able to receive visual information.

Voiced program guides: Voiced program guides provide verbal output of the programming available on the TV. Inclusion in design of voiced program guides will have a high impact for those who are blind or have low vision and a low impact for all other users. Voiced program guides help resolve the issue of not being able to receive visual information.

Ability to adjust program guide font size: Adjustable font size allows the user to set the size of the program guide lettering so that it is comfortable to read. Font size can be an issue for those with visual disabilities and for anyone who is seated at a fair distance from the TV. Inclusion in design will have a high impact for those who have low vision and a low impact for all other users. Adjustable font size will help resolve the issue of not being able to receive visual information.

Ability to adjust program guide font color: Adjustable font color can be used to increase contrast for text information. Inclusion in design will have a high impact for those who have low vision and a low impact for all others. Adjustable color will help resolve the issue of not being able to receive visual information.

Ability to adjust program guide background color: Adjustable background color can also be used to increase contrast for text information. Inclusion in design will have a high impact for those who have low vision and a low impact for all others. Adjustable color will help resolve the issue of not being able to receive visual information.

Ability to adjust CC font size: Adjustable font size allows the user to set the size of the CC lettering so that is comfortable to read. Font size can be an issue for those with visual disabilities and for anyone who is dependent on using CC. Inclusion in design will have a high impact for those who are deaf and hard of hearing, a medium impact for those who have low vision, and a low impact for all other users. Adjustable font size will help resolve the issue of not being able to receive visual or auditory information.

Ability to adjust CC font color: Adjustable font color can be used to increase contrast for text information. Inclusion in design will have a high impact for those who are deaf and hard of hearing, a medium impact for those who have low vision, and a low impact for all other users. Adjustable font size will help resolve the issue of not being able to receive visual or auditory information.

Ability to adjust CC background color: Adjustable background color can also be used to increase contrast for text information. Inclusion in design will have a high impact for those who are deaf and hard of hearing, a medium impact for those who have low vision, and a low impact for all other users. Adjustable CC background color will help resolve the issue of not being able to receive visual or auditory information.

Ability to adjust CC display rate: Adjustable display rate allows the user to set the speed at which CC is displayed. All people read at different rates, and those who have a visual impairment in addition to a hearing impairment may need some additional time to process the CC information. Inclusion in design will have a high impact for those who are deaf or hard of hearing, a medium impact for those who have low vision, and a low impact for all other users. Adjustable CC display rate will help resolve the issue of not being able to receive visual or auditory information.

Concave keys on remote control: Concave or inwardly curved keys help prevent fingers from slipping off the keys, which often results in inadvertent activation of adjacent keys. This type of key also increases the ability to differentiate the keys from each other and from the surrounding area on the device. Inclusion in design will have a medium to high impact for users who are blind, have low vision, or have an upper mobility impairment, and a low impact for all other users. Concave keys will help resolve the issue of locating controls and making accurate inputs.

Compliance with Government Regulations

The primary parts of section 508 that are applicable to TVs address video and multimedia products (1194.24), self-contained closed products (1194.25), functional performance requirements (1191.31), and documentation (1191.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another. The following section 508 regulation is seen as an issue for TVs:

• At least one mode of operation and information retrieval that does not require user hearing must be provided, or support for assistive technology used by people who are deaf or hard of hearing must be provided. Not all programs are captioned, and there are many inaccuracies and lapses in captioning when it is available.

Voice Recognition Software

There are some human limitations that make voice or speech recognition software either inaccessible or difficult to use (and therefore, perhaps, undesirable). While there are very few limitations for any one disability population, all groups may be challenged by getting the software trained, making accurate inputs, overcoming problematic voice characteristics, and dealing with noisy environments. Some of these issues can be overcome through proper design.

Task-Based Accessibility Analysis

The core functionality considered to be necessary to effectively use speech recognition programs consists of the following:

• Using automatic voice recognition phone attendants
• Understanding computerized voices
• Using your voice to control your computer
• Using voice recognition software in public settings
• Using voice recognition software over a headset
• Activating voice input
• Providing appropriate voice input (consider training, vocabulary, speech characteristics)
• Correcting errors

People may have difficulty accomplishing these basic tasks, depending on functional limitations resulting in an impairment, environmental or situational factors that create barriers, and the design of the voice recognition software. Accessibility issues for each disability population were identified, along with an impact rating for each issue. The disability populations include people who have an impairment resulting from environmental or situational factors. The issues identified and the impact ratings assigned for each disability group can be found in the appendix to the online version of this report.

Accessibility Features

A review of various speech recognition software manufacturers’ marketing data failed to identify any features as accessible design components. Features that would make speech recognition accessible include:

Automatic suggestion of alternatives for voice recognition errors: A dictionary is available from which words can be suggested that resemble those that are not understood by the software. If the software is capable of providing good alternatives, this prevents the user from having to continue to attempt the speech input. Implementation in design will have a high impact for people who have cognitive disabilities and a medium impact for all other users. It will help resolve the issue of having difficulty entering information.

Ability to filter out background noise: Noise filters help prevent accidental and perhaps inappropriate input that may go undetected or may cause the user to enter a different mode than desired. Implementation in design will have a high impact for all users and will help resolve the issues of not being able to receive visual or auditory information.

Availability of macros: Macros can be used to enter groupings of information that are often used as input, such as name and address. One voice command is used to cue the system to enter the data set, greatly reducing the amount of verbal input required and reducing error. Implementation in design will have a high impact for all users.

Readback options: Readback allows the user to get feedback on how the voice input has been interpreted. It may be provided as each input is given or after multiple inputs to allow for more continuous data entry. Implementation in design will have a high impact for those with visual impairments and a neutral impact for other users. It will help resolve the issue of not being able to receive visual information.

User manuals in alternative formats: Alternative formats include large print, Braille, and audio. Inclusion in design will have a high impact for users who are blind or have low vision, a medium impact for those who have an upper mobility impairment, and a neutral impact for other disability populations. It will help resolve the issue of not being able to read or handle printed materials.

Ability to pause voice messages: Pause control allows the user to pause the verbal output from the device. This is helpful to give some time to write something down or to think about what option might be desired. Inclusion in design will have a medium impact for users who are blind and a low impact for all other users. Pause control will help resolve the issue of not being able to read text on the screen.

Ability to replay voice messages: Replay control allows the user to listen to a message more than once. This is helpful if the voice output was not understood or could not be heard over environmental sounds. Inclusion in design will have a medium impact for users who are blind and hard-of-hearing users and a low impact for all other users. Replay control will help resolve the issue of not being able to read text on the screen.

Adjustable volume: Volume control is important for auditory alerts. It is particularly important for hard-of-hearing people, but it is useful for all. Inclusion in design will have a medium impact for hard-of-hearing people and a low impact for all other users. It will help resolve the issue of not being able to receive auditory information.

Ability to change voice types: Voice types may consist of male or female, for example. Some voices are more comfortable for a user to listen to; some are better understood by one user than by another. Inclusion in design will have a medium impact for all users. It will help resolve the issue of not being able to receive auditory information.

Ability to adjust the speed of voice messages: A speed that is too slow can negatively affect productivity, but a faster speed may not be well understood by all users. Adjustable speed of voice messages allows the user to set the level that is comfortable for him or her. Inclusion in design will have a medium impact for all users. It will help resolve the issue of not being able to receive auditory information.

Ability to request additional time: Ability to request additional time allows the user to complete a transaction despite the need to use more than the normal amount of allotted time to complete individual transaction components. Inclusion in design will have a high impact for most users, depending on the output mode (visual or auditory) from the device. Additional time will help resolve the issues of not being able to receive visual or auditory information, not being able to reach controls, and not being able to grasp objects.

Headset compatibility: Headsets provide privacy for the user and reduce distraction to neighboring individuals. Headsets also help to control environmental noises that may be misinterpreted by the voice recognition software. Inclusion in design will have a high impact for all users.

Adjustable microphone: Adjustable microphones allow users to reposition the microphone so that the device is at a comfortable level for the user. Users with lower mobility impairments will benefit from the design.

Wireless microphone: Wireless microphones allow users to move about without being directly attached to the device that is being controlled. Users with lower mobility impairments will benefit from the added freedom of movement.

Compliance with Government Regulations

The primary parts of section 508 that are applicable to voice recognition software address software applications and operating systems (1194.21), functional performance requirements (1191.31), and documentation (1191.41). Many of these regulations have an impact on all users; others have a larger impact on one disability group than another.

The following section 508 regulation is seen as an issue for voice recognition software:

• Verify that at least one mode of operation and information retrieval is provided that does not require user vision or, alternatively, that support for assistive technology used by people who are blind or visually impaired is provided.

Conclusions

The final result of the analysis of each product line is the accessibility grade. The overall accessibility grade for a product line is an index of the cumulative impact of all accessibility issues. The accessibility grade is a letter grade on the familiar scale of A, B, C, D, and F. The following definitions are offered for each grade:

A = Excellent accessibility. Users with an impairment are generally able to make full use of the product, with few limitations.

B = Good accessibility. Users with an impairment are able to make good use of the product, but some areas of product functionality are not accessible.

C = Fair accessibility. Users with an impairment can access some of the functionality of the device, but many aspects of product functionality are not accessible.

D = Poor accessibility. Users with an impairment can make use of a small proportion of the functionality of a device, but most aspects of product functionality are not accessible.

F = Accessibility failure. Users with an impairment are generally not able to use the product.

The accessibility letter grades are assigned according to the impact scores calculated for each target population. Details on how these grades were calculated and the task priorities, accessibility levels, and impact scores for each target population for each product line can be found in the appendix to the online version of this report. Accessibility grades may be useful to industry in prioritizing UD efforts and identifying what target populations should be consulted during the design process so that more accessible design features are incorporated into new products.

Table 1. Accessibility Grades for Each Target Population for the Six Product Lines

As these results indicate, certain product lines are very accessible to some target populations but largely inaccessible to others. It would be helpful in informing the UD process and developing products that are more accessible to people with disabilities if designers consulted the target populations for which a product line received accessibility grades of D or F during future product development. For ATMs, users who are blind will likely be unable to use an ATM or portions of the core functionality because of a lack of accessibility features; blind users should be considered in the design of new features for ATMs. Cellular phones are largely inaccessible to users who are blind and users who are deaf. Incorporating more features that make this product line more accessible to these users will expand the market for cellular phones. Distance learning software is largely inaccessible to users who are blind and users who are deaf. Adhering to accessibility regulations and guidelines for designing software will improve the accessibility of distance learning software for these user groups. PDAs are largely inaccessible to users who are blind and users with upper mobility impairments. Televisions were found to be most inaccessible to users who are blind because of an inability to locate, access, and read information, features, and controls. Voice recognition software is largely inaccessible to users who are blind, hard of hearing, or deaf.

IV. Industry Study

The purpose of the industry study was to document universal design practices within industries represented by the six product lines selected for study. Six different companies, representing each of the six product lines, were selected as industry partners. Selection of industry partners was primarily based on their leadership in the marketplace and their ability to deliver candid representations of their experiences with UD. During data collection, every effort was extended to foster an environment in which companies would be able to deliver documentation of actual processes and experiences.

Each company was individually approached by Georgia Tech and asked to participate in the research program. Nondisclosure agreements (NDAs) were signed to assure the companies that Georgia Tech would protect any proprietary data disclosed during the course of the study, as well as to foster a general environment of open and frank discussions. Full disclosure was critical to the success of the industry study, because it was important that actual experiences be documented, as opposed to ideal situations or marketing hype. The NDA restricts Georgia Tech from releasing any proprietary information belonging to the industry partners. Therefore, it is not the intent of this study to provide detailed descriptions of experiences recorded as part of the research. This section documents the general experiences of companies that are representative of the six product lines selected for analysis and provides a basis for identifying candidate interventions or approaches for the promotion of UD.

As part of the industry study, we investigated the presence of barriers and facilitators to accessible design. When an industry partner indicated experiences with a particular barrier, key personnel were interviewed to determine the policies and procedures that were used to overcome the barrier. Before interviewing the industry partners, we identified a candidate list of facilitator and barriers.

Analysis of Facilitators and Barriers to Accessible Design

Source materials, generated as part of the Information Technology Technical Assistance and Training Center (ITTATC), were reviewed to identify potential facilitators to accessible design. Facilitators are defined as concepts, procedures, or actions that can be employed by industry that might result in the development of accessible technologies. We read the needs assessment literature review, a survey of ITTATC National Advisory Committee participants, and a survey of accessibility visionaries in order to create the initial list of facilitators. The list was supplemented by our experience consulting with industry and our preliminary findings from the ITTATC case studies project.

The list of facilitators is divided into five categories: design, organizational, informational, financial, and legal facilitators. Design facilitators are methods or tools that can be implemented in the design process to possibly achieve a more accessible design. Organizational facilitators include augmentations to communications and infrastructure that may enhance the effectiveness of an accessibility program in a company. Informational facilitators address the lack of knowledge in accessible design and the continuation of common misperceptions. Financial facilitators include factors that make accessibility appear to be fiscally attractive. Finally, legal facilitators include legal positions that make accessibility easier to achieve.

Design Facilitators

• Integrate accessibility into engineering processes. Often accessibility of a product can be improved by integrating the consideration of the product’s accessibility as a formal step in the engineering design process. The most desirable outcome is usually observed when accessibility is addressed very early in the design process.

• Develop standardized mechanisms for connecting assistive technologies. A common complaint from industry is that it is difficult to ensure that their products successfully interface with AT, because not enough is known about the detailed interface requirements of the variety of AT products on the market.

• Make technological advancements for handling adaptive devices and flexible design. For example, develop smaller components for connecting assistive devices so that products can be smaller and lighter.

• Develop innovative strategies to promote awareness and understanding of universal design issues. For example, a company could sponsor a design challenge contest to address a specific accessibility concern or award bonuses to those who significantly contribute to the design of a more accessible product.

• Share ideas, concepts, and research with other organizations, including encouragement of peer-reviewed research. Two possible means to accomplish this are by hosting a conference or publishing a journal of accessible design.

• Develop awareness of efforts in accessible design from competing companies.

• Develop accessible design standards and guidelines.

• Develop a tool to help individuals understand their role in universal design.

• Provide training for understanding accessible design, including demonstrations of why a particular approach may not work for an individual with a particular limitation. This will help the designers adjust their approach to thinking about accessible design and developing accessibility design practices in the early phases.

• Fund the acquisition of ergonomic and human performance data for people with disabilities.

• Develop methods for measuring accessibility and comparing the accessibility of two similar products. One approach to addressing these issues would be to start or participate in a working group to develop standardized measurement methods.

• Develop a working group to formulate a clear definition of design goals related to accessibility.

• Promote the benefits of UD. Accessible design is likely to benefit a much larger population than the target group.

• Perform accessibility evaluations on new and existing products and services.

• Include elderly individuals and individuals with disabilities in the design process. Get input from them early and recruit them to participate in evaluations. This can be done through prototype and product testing, focus groups, direct contact with the designers, discussion forums, and other mechanisms.

• Test for product compatibility with assistive technologies.

• Hire product designers with disabilities or with experience in creating universally designed products.

• Hire support personnel with disabilities to work directly with designers.

• Designate an accessibility coordinator to monitor accessibility issues and become familiar with related standards and guidelines.

• Provide concrete design examples of universally designed products.

Organizational Facilitators

• Share accessibility information companywide, and make it part of the culture. Ensure that all departments have the same understanding of accessibility requirements.

• Educate the company on the tangential benefits of accessible design. While most companies recognize that increased accessibility will result in an increase in the user base, some do not realize the benefit of UD for the existing user base.

• Increase diversity in the workforce.

• Develop brown bag and discussion groups regarding accessibility efforts so that upper management has the opportunity to learn about these efforts and factor this information into corporate decisions.

• Ensure that the personnel responsible for making marketing, product development, and design decisions are educated about accessibility and accessible design.

• Educate middle management on how accessible design can be made part of the design process without burdening schedule and budget requirements.

• Recognize accessibility as a necessity for the general population rather than as an exception.

• Incorporate accessibility standards into quality assurance programs.

Informational Facilitators

• Educate employees that people with disabilities have the same wants and needs as people without disabilities (e.g., communication, bill paying, travel). Remind them that the general population suffers from a number of temporary disabilities as well as disabilities related to aging.

• Recognize that relatively small changes can have a large impact on accessibility. Something as simple as reducing the force required to press a button can greatly increase the usability of a product for all potential users without taking away from design creativity.

• Provide accessibility training for managers, designers, sales representatives, customer service personnel, and any other groups that may benefit from the knowledge.

• Advertise accessibility features of products, and emphasize the benefits for everyone.

• Gather as much information about accessibility and disabilities as possible. Survey employees, canvas disability groups for information, hold community meetings to get direct input from people familiar with disabilities, and provide a Web link and/or phone number dedicated to obtaining feedback on product accessibility.

• Form partnerships/relationships with organizations devoted to promoting accessibility.

• Provide information to consumers about their rights under section 508 and section 255 and the company’s efforts to comply with those regulations. Complete voluntary product accessibility templates (VPATs) for products so that consumers can make informed decisions.

• Purchase assistive technologies for designers to work with, and train them to use the devices properly.

• Increase exposure of engineers and designers to accessible design. Train them when they’re hired, develop a short course that can be made available through local universities, and encourage someone in the company to teach at local universities to increase exposure at the university level.

• Recruit employees who have a background in universal design.

• Ask employees (particularly those with temporary or permanent disabilities) to comment on the usability of products they use and to provide design suggestions. Establish a mechanism for employees to provide feedback, and possibly develop a discussion forum from which additional informal feedback can be acquired. Use the people already in the company, as many of them may have experiences with others who have limitations.

Financial Facilitators

Legal Facilitators

• Demonstrate efforts to comply with section 508. Create VPATs.

• Review consumer complaints received by legislators and industry.

• Designate an accessibility expert to monitor government regulations.

• Pressure the government for more detailed requirements that industry must meet or guidelines for satisfying the regulations.

The process used to identify candidate barriers was similar to the process used to identify candidate facilitators. Source materials, generated as part of ITTATC, were reviewed to identify potential barriers to accessible design. Barriers are defined as potential roadblocks to a successful accessibility program. We read the needs assessment literature review, a survey of ITTATC National Advisory Committee participants, and a survey of accessibility visionaries in order to create the initial list of barriers. The list was supplemented by our experience consulting with industry and our preliminary findings from the ITTATC case studies project.

Similar to the list of facilitators, the list of barriers is divided into five categories: design, organizational, informational, financial, and legal barriers. Design barriers are obstacles in the design process that may result in difficulty in achieving an accessible design. Organizational barriers include impediments to communications and infrastructure that may limit the effectiveness of an accessibility program in a company. Informational barriers have to do with the lack of knowledge about accessible design and the continuation of common misperceptions. Financial barriers include factors that make accessibility appear to be fiscally unattractive. Finally, legal barriers include factors that make accessibility difficult to implement because of litigation concerns.

Some of the barriers are merely perceived barriers, resulting from a lack of knowledge of or insufficient experience in accessibility. Other barriers represent more significant challenges to the accessibility community in general.

Design Barriers

• Marketing and technology trends sometimes run counter to accessibility requirements. For example, the cell phone industry has followed a trend in miniaturization that has resulted in the creation of a smaller keypad that is difficult to use for individuals with some types of upper mobility impairments. The font size used for the labels on these keypads has been reduced as well.

• There is a general lack of peer-reviewed research in accessible design. Many human factors professions complain of the lack of human performance research to support design in general. Even fewer studies focus on human performance issues for people with disabilities. In addition, little information exists about standard practices and methods of accessible design in the open literature. Designers simply do not have access to information they need to create accessible products.

• There is a lack of realistic standard guidelines and principles of accessible design.

• Designers lack an understanding of accessible design and what can be achieved if products are designed from the beginning with accessibility in mind. Very few commercially available products exist that represent successful exercises in accessible design.

• Designers do not have access to information about people with disabilities in a format usable to them. Designers often require human performance and ergonomic data in an easy-to-use format to support design decisions. Unfortunately, human performance and ergonomic data for special populations, including people with disabilities, are not a part of the standard data sets. Designers must consult outside sources and attempt to compile the necessary data from a wide variety of technical reports and published articles. The compilation of these data is extremely time-consuming and often unfeasible.

• A standard accessible design process has not been documented, tested, or verified.

• Implementation of multiple methods of display and control may make it difficult to create a streamlined user interface. Many feel that the addition of accessibility features creates an unwieldy user interface.

• There is no standardized method of measuring accessibility or comparing the accessibility of two similar products. Designers do not have a way of determining whether their designs have met their accessibility goals.

• Many feel that there is no clear definition of how accessible a product has to be in order to be considered an accessible design.

• Many designers equate accessible design with designing products for the lowest common denominator.

• Individuals with disabilities are not integrated into the design or evaluation process.

• There is a lack of tools and resources useful for efficiently creating accessible products.

Organizational Barriers

• Often there is a lack of communication across departments about accessibility requirements. A few pockets of accessibility awareness seem to exist in many companies, but there is a lack of structure integrating a comprehensive accessibility program.

• Many companies lack accessibility champions who are in a position to influence company decisions. In many cases, personnel responsible for a company’s accessibility efforts come from human factors, usability, or disability support groups. In general, these groups do not have a large amount of input in corporate decisions.

• Often personnel responsible for making accessibility decisions have little knowledge about accessibility or accessible design.

• Middle management often perceives accessible design to be in direct conflict with schedule and budget requirements.

• Accessibility is often a minor concern compared with other corporate issues, especially in today’s economy.

• There is a lack of infrastructure to support accessible design.

Informational Barriers

• Some view people with disabilities as not having the same wants and needs as people without disabilities.

• Sometimes designers fail to consider the possibility that someone with a disability would attempt to use the products they design.

• Sometimes accessibility features are poorly communicated to the consumers who require the features.

• Specific information about accessibility and disabilities, in general, is not easy to obtain.

• Companies often do not know how to market to people with disabilities.

• Consumers are not familiar with their rights under section 508 and section 255.

• Some designers do not have sufficient access to assistive technology interface requirements.

• Engineers and designers are not sufficiently exposed to accessible design at the university level.

• Accessibility is often interpreted narrowly to include only physical access to the technology.

Financial Barriers

• The cost of developing new technologies associated with accessibility is often seen as prohibitive.

• The target market for accessible design is not well understood or defined.

• There is a general lack of sources of funding for research in accessible design.

• Some people feel that the business case for accessibility is weak.

• It is difficult for companies to market to consumers with disabilities.

• The cost associated with retrofitting existing products is significant.

• The cost associated with purchasing accessible products is often not affordable by people with disabilities.

• The technology required to produce accessible products is not available at a reasonable cost.

Legal Barriers

• Some companies feel that they are under pressure to self-certify compliance with section 508 in order to compete.

• Some feel that federal regulation does not go far enough in detailing the requirements that industry must meet. Others feel that the regulations unnecessarily restrict creative design and innovation.

• Exploration of the federal requirements through litigation is both time-consuming and costly.

• Some companies believe their competition is incorrectly representing its product’s accessibility.

• Procurement officials do not understand accessibility requirements to a sufficient degree. Officials may not be able to recognize when an accessibility claim is false.

• Section 508 is either not being adhered to or is being adhered to inconsistently.

Industry Study Data Collection Methodology

Six companies or industry partners were selected for participation in the study. Once the companies were identified and the points of contact (POCs) established, each was given a list of topics related to accessibility in the company. Georgia Tech requested initial reactions during preliminary phone interviews and then conducted onsite visits and in-person interviews with various individuals involved in the accessibility program. Some industry partners chose to provide detailed documentation and formal responses to our initial inquiries before the interviews. The purpose of the in-person interview was to obtain additional information and documentation to enhance the initial responses provided on the topics of interest.

The data collected were based on a series of topics related to accessibility in each company. The type and format of data requested in response to each of the 10 topic areas is listed below:

1. Documentation of current design practices, with emphasis on user interface design and other aspects of products related to accessibility and UD.

2. Documentation of current product evaluation practices, with emphasis on accessibility and UD.

3. Key personnel who make decisions about product design, product selection, and/or marketing related to accessibility and UD.

4. Current products (fielded or in development) with specific accessibility features or other direct relationship to accessibility.

5. Lessons learned in developing accessible products. Focus on organizational barriers encountered, technical challenges, financial barriers, informational barriers, and legal challenges.

6. Company forecasts of demand and requirements for products with accessibility features.

7. Company training materials related to accessibility and UD.

8. Company-funded research into accessibility and UD.

9. Company contact with members of the disability community relevant to product accessibility and usability by individuals with disabilities.

10. Company position on product accessibility and UD.

Georgia Tech scheduled an initial meeting with the company POC, during which the industry study objectives and data requirements were reviewed in detail. Any readily available information was collected, and the company POC was charged with identifying sources for archival data and arranging personal interviews with individuals qualified to supply the required information. The information analyzed in this summary is based on materials provided directly from the company, notes from the in-person meeting, and publicly available materials.

Analysis of Industry Data: Factors Influencing Adoption of UD Practices

As defined by Tobias and Vanderheiden (1998), the primary factors that influence the adoption of UD principles are government regulation (or the threat of regulation) and profitability. The purpose of the industry study was to build upon previous work and understand how the perception of profitability affects UD. Eleven business concerns have been identified as having an influence on UD practices in an organization. Each business concern has a different level of influence, depending on the strength of the other factors. The factors influencing the adoption of UD practices include the business case, strategy and policy, demand and legislation, marketing and sales, research, design, testing, resource allocation and funding, organization and staff, training, and the customer and consideration of people with disabilities. Detailed descriptions of the impact of each business concern on UD are described below.

Business Case

The business case is the financial justification and plan for including accessibility in product design. Central to consideration of the adoption of UD principles for all six industry partners was the identification of a compelling business case to justify committing the required resources to the effort. Someone at a company wishing to add accessibility features to an existing product or to add schedule and budget to accommodate building accessibility into the design of a new product is often required to justify the added expense by producing either a formal or informal business case for accessibility.

There are several methods that might be used to construct a business case. Each method relies on the interpretation of market forecasts and sales data and is, therefore, somewhat subjective. For example, a senior manager might look at federal sales data and determine that the number of sales at risk because of the production of inaccessible products is negligible and therefore produce a very weak business case for accessibility. A second senior manager might look at the same data and see great potential for increasing the market share of federal sales by enhancing accessibility, therefore determining that the business case for accessibility is strong.

The industry study identified the following primary justifications for the business case for UD:

• Increase market share to include people with disabilities

• Increase federal sales market share

• Reduce risk of losing market share

• Increase overall usability of the product or service

• Reduce risk of costly legal action

• Increase status as a corporate citizen

While increasing market share in general is traditionally regarded as a strong justification for a business case, the potential to increase market share by extending the market focus to cover people with disabilities is often seen as a relatively weak business case, primarily for two reasons. First, the market for people with disabilities is highly segmented. The cost associated with developing a product for users with various disabilities and levels of functional capabilities is not justified by the potential of direct sales to people with disabilities. Second, the amount of disposable income available to people with disabilities is not perceived to be great. The additional cost associated with producing accessible products cannot be passed along directly to consumers with disabilities.

Companies do not appear to fully appreciate the potential value of extending their market share to nontraditional markets through UD. Universal design is generally associated with design for inclusion of people with disabilities. The market analysis documented elsewhere in this report illustrates that this view of the market for UD products is unnecessarily restrictive. Companies representing the six product lines selected for analysis have failed to embrace the extended market perspective for UD products.

The introduction of section 508 of the Rehabilitation Act, requiring federal agencies to consider accessibility in the procurement of most products and services, should have had a direct impact on the calculation of the market size of UD products. Sales to the Federal Government represent a significant portion of sales for many companies producing E&IT products and related services. Based on the face value of section 508, businesses wishing to increase federal sales might do so by developing a
