- Conformance level A
Game With Strobe Effects and No Photosensitivity Mode
2.3.1 — Three Flashes or Below Threshold
Scenario
Setting
A bank's mobile money-transfer screen
What’s wrong
Canvas games with explosion/strobe effects above threshold and no photosensitivity mode.
Example
Open a bank's mobile money-transfer screen and this is what you'll see: canvas games with explosion/strobe effects above threshold and no photosensitivity mode.
Why it matters
People with photosensitive epilepsy and others sensitive to rapid flashing. The practical effect on a bank's mobile money-transfer screen: they can't keep up with content that won't pause.
How to test
Review canvas game explosion/strobe effects with PEAT, and check for a photosensitivity/reduced-effects mode: above-threshold effects with no such mode fail.
How to fix
Nothing may flash more than 3 times per second above the general or red-flash thresholds.
Outcome
That one change on a bank's mobile money-transfer screen means they keep up without being rushed or interrupted.
Who is affected
People with photosensitive epilepsy and others sensitive to rapid flashing.
