|
|
<p>This document provides guidelines for designing <a class="dfn-instance"
|
|
href="glossary.html#def-user-agent" rel="glossary"
|
|
title="Definition of User agent">user agents</a> that lower barriers to Web
|
|
accessibility for people with disabilities (visual, hearing, physical,
|
|
cognitive, and neurological). User agents include HTML browsers and other types
|
|
of software that retrieve and render <a class="dfn-instance"
|
|
href="glossary.html#def-content" rel="glossary"
|
|
title="Definition of Content">Web content</a>. A user agent that
|
|
<a href="conformance.html#Conformance">conforms</a> 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 <a class="dfn-instance"
|
|
href="glossary.html#def-assistive-technology" rel="glossary"
|
|
title="Definition of Assistive technology">assistive technologies</a>).
|
|
Furthermore, all users, not just users with disabilities, should find
|
|
conforming user agents to be more usable.</p>
|
|
<p>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 assistive technology 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.</p>

|
<p>This is the 17 December 2002 Recommendation of "User Agent Accessibility
|
|
Guidelines 1.0." This document has been reviewed by W3C Members, the disability
|
|
community, software developers, and other W3C groups and interested parties,
|
|
and has been endorsed by the Director as a W3C Recommendation. It is a stable
|
|
document and may be used as reference material or cited as a normative
|
|
reference from another document. W3C's role in making the Recommendation is to
|
|
draw attention to the specification and to promote its widespread deployment.

|
This enhances the functionality and interoperability of the Web.</p>
