The HTML 5
<video> element must have an audio description track to provide blind users with information the dialogue does not.
The Algorithm, in Simple Terms
Ensures that every HTML5
<video> element has an audio description.
Why this is Important
While blind people can hear the audio content of videos with no issue, they miss visual aspects of films such as facial expressions and scenes. Audio descriptions fill in these gaps with the context blind people need to get all the information a video conveys.
How to Fix the Problem
Ensure that all
<video> elements have audio descriptions that provide all relevant information that dialogue cannot. Examples of relevant information aside from dialogue include facial expressions and scenes.
