Flash MX: Moving Toward Accessible Rich Media
Macromedia released Flash MX in mid-March of 2002, including enhancements to the player and the authoring tool to improve accessibility for people with disabilities. Admittedly, some areas like screen reader access couldn’t possibly get any worse than they were in previous versions of the player: popular screen readers such as JAWS and Window-Eyes ignored Flash content completely. Other features, such as the ability to add captions (which has been available since Flash 5), benefit from improvements Macromedia made to the Flash architecture in this release. The changes have also automatically improved access to existing Flash content when viewed in the Flash Player 6, but to maximize Flash accessibility for your users you’ll need to publish content from Flash MX.
