DeviceMotionEvent

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The DeviceMotionEvent provides web developers with information about the speed of changes for the device's position and orientation.

Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.

Constructor

DeviceMotionEvent.DeviceMotionEvent()  This API has not been standardized.
Creates a new DeviceMotionEvent.

Properties

DeviceMotionEvent.accelerationRead only
An object giving the acceleration of the device on the three axis X, Y and Z. Acceleration is expressed in m/s2.
DeviceMotionEvent.accelerationIncludingGravityRead 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.rotationRateRead 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.intervalRead only
A number representing the interval of time, in milliseconds, at which data is obtained from the device.

Example

window.addEventListener('devicemotion', function(event) {
  console.log(event.acceleration.x + ' m/s2');
});
