All functionality that uses multipoint or path-based gestures for operation can be operated with a single pointer without a path-based gesture, unless a multipoint or path-based gesture is essential.
Ensure functionality triggered by multipoint or path-based gestures can also be operated with a single pointer.
Supports users who cannot perform complex gestures such as swiping, dragging or drawing complex paths on a screen.
Examples of mistakes where an alternative might have been forgotten:
Check if there is content that requires complex gestures, such as double clicks, long presses, pinching or swiping with multiple fingers.
This doesn't apply to features that control the user agent or assistive technology.
If you design features that require complex gestures, ensure that you design a single-pointer alternative! You aren't forbidden to have complex gestures in use, but they must have alternatives.
