RE: Animation conveying information

It may be a non-conformance of SC 1.4.1: Use of Color if the change of colour does not have a contrast ratio of at least 3:1.

Also, if the button changes from not pulsing to pulsing it would be indicating a change of state, so the information would need to be conveyed programmatically as per SC 1.3.1 and 4.1.2.

It may also be a non-conformance of SC 2.3.1: Three Flashes or Below Threshold and/or SC 2.2.2: Pause, Stop, Hide.

Subject: Animation conveying information

Hello

This is maybe niche and something I haven't seen before. I have a website which uses animation to convey information. For example, to show that you must click a button next, the button pulses. This is information conveyed by movement. It isn't really time based media and it isn't really non-text content... it is animation/movement used to convey instruction.

What SC would you align this with please? It is almost sensory characteristics but the instruction is implicit in the animation...

It needs an alternative for people who can't perceive the animation, would this be 1.1.1? Or 1.2.1?

Thanks

Sarah
