# On Gesture
Register an [event handler](/reference/event-handler) that will execute whenever the user executes a gesture withthe BBC micro:bit.
Start an [event handler](/reference/event-handler) (part of the

you do a **gesture** (like shake, tilt, or drop the micro:bit).
```sig
input.onGesture(Gesture.Shake,() => {
})
```
