Success Criteria
1.1.5 Facilitate Clear Display of Alternative Content for Time-based Media: For recognized on-screen alternative content for time-based media (e.g. captions, sign language video), the following are all true: (Level AA)
- Don't obscure controls: Displaying time-based media alternatives doesn't obscure recognized controls for the primary time-based media.
- Don't obscure primary media: The user can specify that displaying time-based media alternatives doesn't obscure the primary time-based media.
- Use configurable text: The user can configure recognized text within time-based media alternatives (e.g. captions) in conformance with 1.4.1.
Note: Depending on the screen area available, the display of the primary time-based media may need to be reduced in size to meet this requirement.
Tests
Test Procedure 1
- Identify types of time-based media content (e.g. by exploring the UI or consulting Help documentation).
- Open a test document that contains examples of these types of time-based media content that have alternatives (e.g. video with captions, video with audio descriptions, video with extended audio descriptions, video with sign language).
Sample HTML test document: File time-based media with alternatives - For each example:
- With the alternative content displayed, check that you can still operate the controls (in all modalities, e.g. mouse, keyboard, touch) for the primary time-based media
- With the alternative content displayed, check that you can still see/hear the primary time-based media.
- For text-based alternatives (e.g. captions), check that you can adjust the text scale
- For text-based alternatives (e.g. captions), check that you can adjust the text color and background color, choosing from all platform color options
- For text-based alternatives (e.g. captions), check that you can adjust the font family, choosing from all installed fonts
- For text-based alternatives (e.g. captions), check that you can adjust the line spacing, choosing from a range with at least three values
Note: For many user agents you might have to add an extension to gain this ability.
Expected Results 1
- Check #3 is true for each content example tested
