This document provides guidelines for designing user agents 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 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, are expected to find conforming user agents to be more usable.
In addition to helping developers of HTML browsers, media players, etc., 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.

This is the 21 August 2002 Last Call Working Draft of "User Agent Accessibility Guidelines 1.0". The last call review period ends 18 September 2002. Last Call Working Draft status is described in section 5.2.2 of the Process Document. Since the previous Candidate Recommendation draft, the UAWG has gathered implementation experience and clarified the document based on in-depth discussions with user agent and assistive technology developers.
As a result of the second Candidate Recommendation period, the UAWG:
The chapter on conformance has also been greatly simplified since the Candidate Recommendation. The complete list of changes is available on the Web.
In this review, the User Agent Accessibility Guidelines Working Group is primarily interested in comments on changes since the Candidate Recommendation. The Working Group does not expect to make substantial changes to this document as the result of this review; the document has already received substantial technical review. The UAWG does expect to make clarifications and to record issues to be addressed after UAAG 1.0.
The latest information regarding patent disclosures related to this document is available on the Web. As of this publication, there are no disclosures.
