Whats All This Talk About Web Accessibility, Part 1: Inside Adaptive Technology
Web accessibility has different meanings for different people. For one person, it might mean the user-friendliness of a Web site, for another it might mean ease of understanding a Web site. Yet other meanings may focus on ease of access via connection speeds or the clarity of Web site navigation.
For a visually impaired or blind person, Web accessibility is more clearly defined as the difference between accessing or not accessing Web content, regardless of any of the meanings mentioned above. In other words, your Web site may be truly informative, but if it's not designed for accessibility, a visually impaired or blind person will never have the opportunity to find out.
Depending on which statistics you listen to, 6% of the population in the United States is visually impaired or blind. Although this may seem like a small number, it amounts to an estimated 15 million people.
