How did AI improve accessibility on the Internet

ARIA

Introduction to ARIA

Web applications and ARIA FAQ
Answers to the most frequently asked questions about WAI-ARIA and why it is necessary to make web applications accessible.
Videos from screen readers with ARIA
Take a look at simplified examples and practical examples for ARIA. "Before and after" examples can also be found here.
Using ARIA with HTML
Here you will find practical recommendations for developers. For example which attributes should be used with which HTML elements.

Easy improvements with ARIA

Enhancing Page Navigation with ARIA Landmarks
An introduction to improving page navigation for screen reader users with ARIA landmarks. Also read the article on Implementing ARIA Landmarks and check out existing ARIA Landmark websites (last updated July 2011).
Improving the accessibility of forms
ARIA isn't just for dynamic content! Learn how to improve the accessibility of HTML forms with the help of ARIA attributes.
Live regions (work-in-progress)
Live regions provide screen readers with information on how to deal with content changes on websites.
Using ARIA Live Regions to Announce Content Changes
A brief overview of live regions from the makers of the screen reader software JAWS. Live regions are also supported by NVDA in Firefox and VoiceOver in Safari (from OS X Lion and iOS 5).

ARIA for JavaScript widgets

Keyboard driven JavaScript components
The first step in creating an accessible JavaScript widget is to make it keyboard navigable. This article shows the work steps that are necessary for this. The Yahoo! Focus Management also provides a good description.
Keyboard navigation style guide
Getting developers to implement it consistently is a challenge at ARIA, which of course would be best for users. This style guide describes the keyboard functions for known widgets.

Also includes presentations and examples.

Mailing list

Free ARIA Google Group
Here you can ask questions about ARIA and make suggestions to improve this ARIA documentation.

Blogs

ARIA information from blogs is usually quickly out of date. However, there is some helpful information from other developers who work with ARIA.

Report an error

Write ARIA bug reports on browsers, screen readers, and JavaScript libraries.

Examples

Directory for ARIA examples
Some sample files with basic structure from which one can learn.
Examples of accessible JS widget libraries
Dojo, jQuery, Fluid, YUI
Yahoo! Mail
Yahoo! has at Yahoo! Mail done a great job. A web app that looks almost like a native app and works very well, like a review on Yahoo! Mail from screen reader user Marco Zehe shows. His comment: "Keep up the good work!".
Yahoo! Search
Yahoo! has also done a very good job here, fully exploiting the possibilities with ARIA and documenting the technology in detail. At Yahoo! Search uses a combination of ARIA landmarks, live regions and widgets.

Standardization efforts

Overview of the WAI-ARIA activities of the W3C
Overview of efforts to standardize AI-ARIA from the Web Accessibility Initiative (WAI).
WAI-ARIA specification
The specification of the W3C is very useful as a reference. At this stage it is essential to carry out a compatibility test, as the implementations still differ from one another.
WAI-ARIA Authoring Practices
As with the WAI-ARIA specification of the W3C, the official best practices represent an ideal for the future - the point in time at which it can be assumed that ARIA support is consistently implemented in all browsers and screen readers. The W3C documents allow in-depth insight into the structure of ARIA.

For now, web developers implementing ARIA should maximize compatibility by referring to the documentation of best practices and examples.
Open AJAX Accessibility Task Force
The Open AJAX Effort Centers on topics such as developer tools, sample files and automated tests for ARIA.
In development: WCAG 2.0 ARIA techniques
The community needs a complete set of WCAG techniques for WAI-ARIA + HTML in order for organizations to be confident that their ARIA-enhanced content is WCAG-compliant. This is especially important when rules and regulations are based on WCAG.
