accessibility

From Authoring Tool Accessibility Guidelines 1.0 (2000-02-03) | Glossary for this source

Within these guidelines, "accessible Web content" and "accessible authoring tool" mean that the content and tool can be used by people regardless of disability.To understand the accessibility issues relevant to authoring tool design, consider that many authors may be creating content in contexts very different from your own: They may not be able to see, hear, move, or may not be able to process some types of information easily or at all;They may have difficulty reading or comprehending text;They may not have or be able to use a keyboard or mouse;They may have a text-only display, or a small screen.Accessible design will benefit people in these different authoring scenarios and also many people who do not have a physical disability but who have similar needs. For example, someone may be working in a noisy environment and thus require an alternative representation of audio information. Similarly, someone may be working in an eyes-busy environment and thus require an audio equivalent to information they cannot view. Users of small mobile devices (with small screens, no keyboard, and no mouse) have similar functional needs as some users with disabilities.
