Animations, sounds and flashes can be paused.

Allow the user to pause animated gifs, jingles, sound or visual animations

Objectives

• Let the user control the animations when viewing content.
• Allow step-by-step consultation of sequential animations or sound content.
• Making content accessible to people with disabilities

Implementation

For visual animation lasting > 5 seconds or sound lasting > 3 seconds, systematically provide the multimedia object with the necessary control means: start, stop, mute or volume. Do not use animated graphics that are not controllable or partially controllable by the user (animated gif images in particular). In the OPF metadata, indicate this metadata:noFlashingHazardnoMotionSimulationHazardnoSoundHazard

Control

• In each page containing a visual animation or sound: Check the possibility of stopping the animation, sound or flashing (pause, restart, sound volume if applicable).

Validation

• Needs to be human verified.
