This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
Summary
The DeviceMotionEvent provides web developers with information about the speed of changes for the device's position and orientation.
Warning: Currently, Firefox and Chrome does not handle the coordinates the same way. Take care about this while using them.
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 express 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');
});
