Multimedia Accessibility

Design multimedia content that can be consumed by people who can't hear the audio, can't see the video, or can't process both at once.

Core Principle

Every piece of information conveyed through one sense must also be available through another. Audio content needs a visual equivalent. Visual content needs an audio or text equivalent.
