Checkpoint 1.7 - Flash

Hide child objects of animation

WCAG 1.0 Priority 2

WCAG Guideline 6. Ensure that pages featuring new technologies transform gracefully.

When animated objects change on the stage of a Flash movie, a screen reader receives a prompt that something has changed and starts reading the page information from the top. This can make the page unusable for screen reader users. To prevent the screen reader from constantly refreshing, all child objects of animations should be hidden.

Requirement

Hide all child objects of animations.

Recommendation

Deselect Make Child Object Accessible option in the Flash Accessibility Panel or by using the .forcesimple property of Action Script.

Checking Tool

Use Flash Player 6 or newer to browse Flash content and a screen reader to test its accessibility.
