Tips for creating 508 compliant Adobe Captivate SWF files
While Adobe Captivate Section 508 output is compliant for navigation, you should also make
sure other elements are compliant in your topics. Assistive software needs to be able to “read”
elements on the screen to visually impaired users. Use these tips to help you design accessible
projects.
•
In the Project Properties dialog box, write a meaningful name and description for your Adobe
Captivate projects.
•
For users with hearing impairment, add text equivalents for audio elements. For example,
when delivering narrative audio, it is important to provide captions at the same time. One
option is to place a transparent caption in a fixed location on slides, then synchronize the text
with the audio using the Timeline.
•
If your project contains visual multimedia, provide information about the multimedia for users
with visual impairment. If a name and description are given for visual elements, Adobe
Captivate can send the information to the user through the screen reader. Be aware of audio in
your Adobe Captivate projects that might interfere with a user being able to listen to the screen
reader.
•
Write specific text assigned to individual slides for screen readers to read.
•
Ensure that color is not the only means of conveying information. For example, active links
that use a blue font color to indicate that they are active should also use another type of
formatting (such as bold, italics, or underlined text). In addition, make sure that foreground
and background contrast sufficiently to make text readable for people with low vision and
color blindness.
•
For users with either visual or mobility impairment, ensure that controls are device
independent or accessible by keyboard.
•
Users with cognitive impairments often respond best to uncluttered design that is easily
navigable.
•
If mouse movement is critical in your Adobe Captivate project, consider changing the mouse
pointer so it is double the normal size for easier viewing.
•
Document methods of accessibility for users.
•
Avoid looping objects. When a screen reader encounters Flash content on a page, the screen
reader notifies the user with audio, such as “Loading….load done”. As content in a project
changes, the Flash Player sends an event to the screen reader notifying it of a change, which
causes the screen reader to return to the top of the page and begin reading again. Therefore, a
looping text animation on a slide, for example, might cause the screen reader to continually
return to the top of the page. This could be annoying for users relying on a screen reader.
