Accessibility For Hearing-Impaired Users - MACROMEDIA FLASH MX 2004-USING FLASH Use Manual

Because static text cannot be assigned an instance name, it cannot be included in the list of the
property values. As a result, a single instance of static text anywhere in the SWF file
tabIndex
causes the reading order to revert to the default.
To specify a tab order, you assign an order number to the
following example:
_this.myOption1.btn.tabIndex = 1
_this.myOption2.txt.tabIndex = 2
See
Button.tabIndex
Language Reference.
You can also use
MovieClip.tabChildren
ActionScript Language Reference.

Accessibility for hearing-impaired users

To provide accessibility for hearing-impaired users, you can include captions for audio content
that is integral to comprehending the material. A video of a speech, for example, would probably
require captions for accessibility, but a quick sound associated with a button probably wouldn't.
There are several ways you can add captions to a Flash document, including the following:
•
Add text as captions, taking care to ensure the captions are synchronized on the Timeline with
the audio.
•
Use Hi-Caption Viewer, a component available from Hi Software that works with Hi-Caption
SE for use with Flash. The white paper titled Captioning Multimedia with Hi-Caption SE for
Use with Macromedia Flash MX explains how to use Hi-Caption SE and Flash together to
create an a captioned document. The white paper is available on the Macromedia website on
the Accessibility White Papers page at
whitepapers/. For more information on Hi-Caption SE, see the link on the Macromedia
Accessibility Captioning page at
