Hello all... I would like to get the Lists input on some Guidelines Macromedia will be publishing in the coming weeks on making flash content accessible... They are based loosely on the WAI top 10 (those that apply to Flash). Guidelines follow: Text Alternatives Whenever using narrative, or synchronized sound, provide the option of a text based caption that describes the audible events and gives a visual representation of the content as it is displayed. Provide captioning and transcripts of audio, and descriptions of video. Text alternatives should also be included with the HTML document associated with the Flash (SWF) movie. Descriptive Links When providing navigation elements, or links to various parts of a flash movie or site, make sure to provide descriptive link names. Links such as "Click here", "Click this", or no description at all, give little or no information to users who depend on assistive technologies. Creating flash (SWF) movies with clear descriptions of nativation elements helps tremendously, not only with accessibility, but with overall usability of a site in general. Page Organization Another important factor to take into consideration when creating a site that can be viewed by users with disabilities is consistent and easily navigable interfaces. Presenting a clearly marked navigation element at the beginning of a site and then disregarding that interface in other parts of the site only leads to confusion and inconsistency when trying to navigate a site with limited input or control. Graphs Tables & Charts When displaying charts or graphs, supply a description of the data in a form that facilitates line-by-line reading. If using a flash element within an HTML page to display an information based graphic, make sure to provide the necessary descriptive content in an <ALT> or <LONGDESC> tag. This can be accomplished using the provided HTML publish template, and placing a descriptive text box on the same frame as the flash graphic within the Flash (SWF) movie. Ensure User Control If your site or presentation contains audio, narration, or animated graphics, provide the ability to stop and start those elements. An example of the ability to stop and start sound when using "Streaming" audio is provided within the Flash Accessibility Kit under "Adding Audio Tracks for Visual Elements." For linear animations simply providing a button within the movie interface that issues a "stop()" or "play()" command can solve many of the issues related to user control. -- Michael Williams Macromedia Flash Team 415-832-5991
