User Agent Accessibility Guidelines (UAAG)

The User Agent Accessibility Guidelines (UAAG) documents explain how to make user agents accessible to people with disabilities, particularly to increase accessibility to Web content. User agents include Web browsers, media players, and assistive technologies, which are software that some people with disabilities use in interacting with computers.

UAAG is part of a series of accessibility guidelines, including the Web Content Accessibility Guidelines (WCAG WG) and the Authoring Tool Accessibility Guidelines (ATAG). Essential Components of Web Accessibility explains the relationship between the different guidelines.

Who UAAG is for

UAAG is primarily for developers of Web browsers, media players, assistive technologies, and other user agents.

UAAG and supporting resources are also intended to meet the needs of many different audiences, including policy makers, managers, and others. For example:

What is in UAAG 1.0

UAAG 1.0 contains a comprehensive set of checkpoints that cover:

Technical document format

UAAG 1.0, the techniques documents, and the checklist follow the W3C format for technical specifications which includes several sections at the beginning: links to differnt versions, editors, copyright, abstract, and status with the link to errata and the email address for comments. Most WAI specifications have a link at the top to the Table of Contents.

UAAG Versions: 1.0 and 2.0

User Agent Accessibility Guidelines 1.0 was approved in December 2002 and is the stable and referenceable version.

UAAG 2.0 is being developed to help make future generations of Web browsers more accessible, to provide alternative information based on the users technology and platform, and to align with WCAG 2.0 and ATAG 2.0. WAI anticipates UAAG 2.0 may be completed in 2013. Because of the nature of the W3C development process, WAI cannot be certain when the final version of UAAG 2.0 will be available. UAAG 1.0 will remain the latest approved version until version 2.0 is complete.

Currently UAAG 2.0 is a mature draft and we expect that the main content will not change significantly. We recommend that you use the UAAG 2.0 draft in most cases, understanding that it might change.

Who develops UAAG

UAAG technical documents are developed by the User Agent Accessibility Guidelines Working Group (UAWG), which is part of the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI). For more information about the working group, see the UAWG page.

How WAI Develops Accessibility Guidelines through the W3C Process: Milestones and Opportunities to Contribute describes formal periods for public review. Opportunities for review and comment of WAI documents are announced on the WAI home page and WAI Interest Group mailing list. An email address for sending comments is included in the "Status of this Document" section.

Opportunities for contributing to UAAG and other WAI work are introduced in Participating in WAI.
