Rapid Hover Effect That Flashes When a Key Autorepeats

2.3.1 — Three Flashes or Below Threshold

Scenario

Setting

An insurance company's claims form

What’s wrong

Hover/press effects that rapidly toggle high-contrast states when a key autorepeats.

Example

Try this on an insurance company's claims form: hover/press effects that rapidly toggle high-contrast states when a key autorepeats.

Why it matters

People with photosensitive epilepsy and others sensitive to rapid flashing. On an insurance company's claims form specifically, they run out of time before finishing the task.

How to test

Hold down a key that triggers a rapid hover/press toggle effect (autorepeat): check whether the resulting flicker exceeds the flash threshold.

How to fix

Nothing may flash more than 3 times per second above the general or red-flash thresholds.

Outcome

Fixed, a visitor to an insurance company's claims form can read the content without losing their place.

Who is affected

People with photosensitive epilepsy and others sensitive to rapid flashing.
