Use gestural signifiers

Gestural interfaces, like those on smartphones and touchscreens, rely on users recalling specific hand movements to interact with the device. Since these gestures aren't always obvious, make use of gestural signifiers — visual cues that help users remember what to do. These cues guide the user, making interaction smoother and more intuitive. For example, in a touchscreen navigation app, an animated hand icon could demonstrate pinching to zoom in on the map.

Best practices for using gestural signifiers include:

• Keep gestures and their signifiers consistent across the interface to strengthen memory.
• Make sure signifiers are clearly visible where gestures are needed.
• Use simple and natural gestures that align with common human actions.
