Users can interact with a CarPlay app by performing gestures on the car’s built-in touchscreen display. CarPlay supports both low-fidelity and high-fidelity touchscreen displays. High-fidelity screens have lower finger-tracking latency than low-fidelity screens, and therefore support more gestures. Depending on the display, CarPlay apps can respond single-finger gestures, as follows.
|Gesture||Usage||Low-fidelity screen||High-fidelity screen|
|Tap||Activates a control or selects an item.|
|Double-tap||Zooms in and centers content.|
|Touch and hold||Activates a control for a period of time. For example, touching and holding the Next Track button in the Music app fast-forwards the currently playing track.|
|Flick||Scrolls or pans quickly.|
|Drag||Moves an element from side-to-side or drags an element across the screen.|
