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

The DeviceOrientationEvent provides web developers with information from the physical orientation of the device running the web page.

Constructor

DeviceOrientationEvent.DeviceOrientationEvent(): Creates a new DeviceOrientationEvent.

DeviceOrientationEvent.absolute Read only: A boolean that indicates whether or not the device is providing orientation data absolutely.
DeviceOrientationEvent.alpha Read only: A number representing the motion of the device around the z axis, express in degrees with values ranging from 0 (inclusive) to 360 (exclusive).
DeviceOrientationEvent.beta Read only: A number representing the motion of the device around the x axis, express in degrees with values ranging from -180 (inclusive) to 180 (exclusive). This represents a front to back motion of the device.
DeviceOrientationEvent.gamma Read only: A number representing the motion of the device around the y axis, express in degrees with values ranging from -90 (inclusive) to 90 (exclusive). This represents a left to right motion of the device.
DeviceOrientationEvent.webkitCompassHeading Read only: A number represents the difference between the motion of the device around the z axis of the world system and the direction of the north, express in degrees with values ranging from 0 to 360.
DeviceOrientationEvent.webkitCompassAccuracy Read only: The accuracy of the compass means that the deviation is positive or negative. It's usually 10.

window.addEventListener('deviceorientation', function(event) {
  console.log(event.alpha + ' : ' + event.beta + ' : ' + event.gamma);
