Interface commitments
Navigation and controls are keyboard reachable, focus remains visible, status changes use aria-live, color states also use text, and controls target at least 44 pixels on touch screens. Reduced-motion preferences disable nonessential movement.
Special test behavior
Keyboard tests provide a clear focus and stop action. Pixel tests use manual changes with no rapid flashing. Audio tests warn about volume. Camera status is always stated in text. Fullscreen modes include a visible Exit button and Escape guidance.

Tell us the page, assistive technology, browser and the task you could not complete. Do not include private test data. We prioritize a usable alternative when a device API itself is inaccessible.
