Success Criterion 2.5.1 - Level A
Pointer Gestures
Ensure users can operate the interface with one finger using simple gestures. Not everyone is able to pinch-to-zoom or trace a certain path. Provide an alternative, such as a button, that allows the user to perform the same action.
Impact
It can be difficult for people with a motor disability to use multiple fingers. By offering an alternative, they can use the same functionality.
It can be difficult for people with a motor disability to make path-based gestures. Make sure that path-based gestures are not necessary to operate the app.
Check
“Is an alternative available for multipoint and path-based gestures?“
This can be tested without assistive technologies. The table below lists examples of gesture types.
| Type | Examples |
|---|---|
| Single pointer | One finger clicking, tapping, pressing, swiping |
| Multipoint | Pinching, rotating, multi-finger clicking, tapping, pressing, swiping |
| Path-based | Tracing, drawing, twisting |
