Web Accessibility
Web Accessibility Enabling your Web site to meet the needs of individuals with disabilities is an issue relevant to all businesses. Persons with disabilities make up a significant portion of the population, and legal ramifications exist for Web sites that discriminate by not providing adequate and universal access to the site’s resources. In this chapter, we explore the Web Accessibility Initiative and its requirements, various laws regarding businesses are their availability to people with disabilities and how some companies have developed their systems, products and services to meet the needs of this demographic. 7.11.1 Accessibility: Regulations and Technologies In 1999, a lawsuit was filed by the National Federation for the Blind (NFB) against AOL for not supplying access to its services to people with visual disabilities, a mandate of the Americans with Disabilities Act of 1990. [***D.Z. “They Oughta Pass a Law, and They Did, but Is It Working,” Presentations September 2000: 45.***] Many other efforts have been made to address this issue (Fig. 14.1). WeMedia.com™ (Fig. 14.2) is a Web site dedicated to providing disabled individuals with the same opportunities as the general population. The site serves 54 million disabled consumers with an estimated $1 trillion in purchasing power. [***<www.wemedia.com>***]We Media provides online educational opportunities for people with disabilities. Act Purpose Americans with Disabilities Act The ADA prohibits discrimination on the basis of disability in employment, state and local government, public accommodations, commercial facilities, transportation, and telecommunications. [***Americans with Disabilities Act***] Telecommunications Act of 1996 The Telecommunications Act of 1996 contains two amendments to Section 255 and Section 251(a)(2) of the Communications Act of 1934. These amendments require that communication devices, such as cell phones, telephones and pagers, be accessible to individuals with disabilities. [***<www.usdoj.gov/crt.ada/ cguide.htm#anchor63109>***] Individuals with Disabilities Education Act of 1997 Educational materials in the school setting must be made accessible to children with disabilities.

The Internet has also enabled disabled individuals to work in a vast array of new fields. Prior to its advent, 25 percent of the 15 million Americans with disabilities found employment as a result of the Americans with Disabilities Act (ADA). [***M. Conlin, “The New Workforce,” Business Week 20 March 2000: 65.***] Technologies such as voice activation, visual enhancers and auditory aids afford disabled individuals with more work opportunities. For example, visually impaired people might use computer monitors with enlarged text or electronic equipment with braille operating controls. Within the next year, information provided through technology will have to be equally accessible to individuals with disabilities. [***M. Conlin, “The New Workforce,” Business Week 20 March 2000: 65.***] For example, federal regulations similar to the disability ramp mandates will be applied to the Internet to meet the needs of those with impaired hearing, sight and speech. In the future, sites heavily laden with graphic images might have to simplify their appearance. [***S.

All Rights Reserved. 7.11.2 Web Accessibility Initiative On April 7, 1997, the World Wide Web Consortium (W3C) launched the Web Accessibility Initiative (WAI™). Accessibility refers to the level of usability of an application or Web site for people with disabilities. The vast majority of Web sites are considered inaccessible to people with visual, learning or mobility impairments. A high level of accessibility is difficult to achieve, because there are many different disabilities, language barriers, hardware and software inconsistencies, etc. As greater numbers of people with disabilities begin to use the Internet, it is imperative that Web-site designers increase accessibility to their sites. The WAI is an attempt to make the Web more accessible; its mission is described at www.w3.org/WAI. Chapter 34, Accessibility, discusses programming techniques used to provide users with disabilities Internet access through both wireless and wireline devices. The Web Content Accessibility Guidelines 1.0 (www.w3.org/TR/WCAG10) are divided into a three-tier structure of checkpoints according to their priority. Priority-one checkpoints are those that must be met to ensure accessibility. Priority-two checkpoints, though not essential, are highly recommended. Priority-three checkpoints improve accessibility slightly. The WAI also presents a supplemental list of quick tips—this list contains checkpoints aimed at solving priority one problems. More information on the WAI Quick Tips can be found at www.w3.org/WAI/References/Quicktips.) 7.11.3 Web Accessibility and Wireless Devices Wireless technology will profoundly improve the lives of people with disabilities. For example, wireless technology may be used to help visually impaired people navigate. Consider a visually impaired person trying to cross a busy intersection. The traffic light could be equipped with Bluetooth technology to broadcast messages to Bluetooth-enabled GPS wireless devices. The wireless device would receive a signal that the crossing sign says “Walk” and would then convert that message to audio for the person to hear. The device could also warn the person on-coming traffic and tell the person when it is safe to walk. Wireless technology may also help hearing-impaired people. For example, a hearingimpaired person shopping in a mall cannot hear an announcement about a sale in a store. Using Bluetooth technology, the mall could broadcast the announcement to the person’s Bluetooth-enabled PDA device, which would convert the speech to text and display the text message for the hearing-impaired person. The same technology could be used to connect the PDA wirelessly to a television or radio to provide closed captioning for broadcasts. Wireless applications designed for people with disabilities are also discussed in Chapter 3, Location-Based Services and Chapter 34, Accessibility, walks the user through programming techniques designed to provide users with disabilites Internet access. In this chapter, we explore how electronic communications, including the growing wireless phenomenon, have affected our legal system, as well as our social structure. We investigated issues relating to privacy, defamation, Internet taxation and copyright. We also examined how wireless communication has advantages and disadvantages. In the next chapter, International Wireless Communications, we discuss how the wireless Internet is being developed in regions worldwide, and compare this growth to that of the United States.
