- Success Criterion 2.5.1
- Conformance level A
Map or Image Zoomable Only by Pinch Gesture
2.5.1 — Pointer Gestures
Scenario
Setting
A childcare-booking service's scheduling page
What’s wrong
Pinch-to-zoom as the only zoom on maps/images (no +/– controls).
Example
During an audit of a childcare-booking service's scheduling page: pinch-to-zoom as the only zoom on maps/images (no +/– controls).
Why it matters
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems. On a childcare-booking service's scheduling page, that means they get stuck and can't reach the control.
How to test
Try to zoom a map/image using +/- buttons instead of pinching: if only pinch-to-zoom is offered, it fails.
How to fix
A single-tap/click alternative must exist for every path-based or multi-point gesture.
Outcome
With the fix in place on a childcare-booking service's scheduling page, they keep track of where they are on the page.
Who is affected
People with limited hand mobility and users of head-pointers, sticks, or eye-gaze systems.
