Method of interaction (keyboard, mouse, touch, voice). Interfaces should support multiple modalities.
A property of interfaces that can be used with a variety of inputs (keyboard, touch, voice, switch), not requiring a specific device.
Actions like pinch, swipe, or drag. WCAG requires a single-pointer alternative that does not depend on complex gestures.
Transient content that appears on hover or focus, which must be dismissible, hoverable, and persistent while being hovered.
Controls should not require precise pointer targeting; provide generous hit areas and visible affordances.
Design that allows users to cancel or undo pointer actions to prevent accidental activation.
