# Window: devicemotion event



The **`devicemotion`** event is fired at a regular interval and indicates the acceleration rate of the device with/without the contribution of the gravity force at that time. It also provides information about the rate of rotation, if available.

This event is not cancelable and does not bubble.

## Syntax

Use the event name in [addEventListener()](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget%2FaddEventListener):

```js-nolint
addEventListener("devicemotion", (event) => { })
```

Alternatively, assign to the [event handler property](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Events#using_onevent_properties) of the interface:

```js-nolint
ondevicemotion = (event) => { }
```

## Event type

A [DeviceMotionEvent](https://developer.mozilla.org/en-US/docs/Web/API/DeviceMotionEvent). Inherits from [Event](https://developer.mozilla.org/en-US/docs/Web/API/Event).

## Examples

```js
function handleMotionEvent(event) {
  const x = event.accelerationIncludingGravity.x;
  const y = event.accelerationIncludingGravity.y;
  const z = event.accelerationIncludingGravity.z;

  // Do something awesome.
}

window.addEventListener("devicemotion", handleMotionEvent);
```
