2.5.4 Motion Actuation
동작 기반 작동
Summary
Functions triggered by shaking or tilting the device need a conventional UI alternative, and the motion trigger must be switchable off. Users with a mounted device cannot shake it, and users with tremor trigger it by accident. "Shake to undo" is the canonical example.
Common failures
- Providing undo only through a shake gesture, with no on-screen undo control.
