LANG-21: If multi-point or path-based pointer gestures are used, ensure that a single-pointer non-path alternative is provided.
How to test
- Identify instances of functionality that requires multi-point or path-based pointer gestures.
- Confirm that that functionality is also available by another means which does not require such gestures.
- A multi-point or path-based gesture is essential (e.g. providing a signature on a touch screen).
How to fix
Provide an additional mechanism for every complex gesture (e.g. supplement pinch and zoom with keyboard accessible zoom buttons).
