Implementing UAAG 2.0: A guide to understanding and implementing User Agent Accessibility Guidelines 2.0

This document provides supporting information for the User Agent Accessibility Guidelines (UAAG) 2.0 for designing user agents that lower barriers to Web accessibility for people with disabilities. User agents include 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, should find conforming user agents to be more usable. In addition to helping developers of 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. This document provides explanation of the intent of UAAG 2.0 success criteria, examples of implementation of the guidelines, best practice recommendations and additional resources for the guideline. The "User Agent Accessibility Guidelines 2.0" (UAAG 2.0) is part of a series of accessibility guidelines published by the W3C Web Accessibility Initiative (WAI).
