About animation and accessibility

In some situations you may want to change the property of an accessible object during the course of movie playback. For example, you may want to indicate changes that take place on a keyframe in an animation.

To update properties for an accessible object, display the frame in which you want to change the properties, and change the properties for that object as needed.

Different screen readers treat new objects on frames differently. Some screen readers may read only the new object. Some screen readers may re-read the entire movie.
