Operable / 2.5 Input Modalities

2.5.1Pointer Gestures

Level A

For functions operated by multi-point or path-based gestures like pinch-to-zoom or swipe, provide a single-pointer alternative such as zoom buttons or previous/next buttons, since tracing a precise path is hard for users with tremor or limited dexterity. Exempt when the path itself is essential, as with signature input.
