Window: devicemotion event

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

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.


Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("devicemotion", (event) => {});

ondevicemotion = (event) => {};

Event type

Event properties

DeviceMotionEvent.acceleration Read only

An object giving the acceleration of the device on the three axis: x, y, and z. Acceleration is expressed in m/s².

DeviceMotionEvent.accelerationIncludingGravity Read only

An object giving the acceleration of the device on the three axis: x, y, and z with the effect of gravity. Acceleration is expressed in m/s².

DeviceMotionEvent.rotationRate Read only

An object giving the rate of change of the device's orientation on the three orientation axis: alpha, beta and gamma. Rotation rate is expressed in degrees per seconds.

DeviceMotionEvent.interval Read only

A number representing the interval of time, in milliseconds, at which data is obtained from the device.


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, true);
