devicemotion event

The devicemotion event is fired at a regular interval and indicates the amount of physical force of acceleration the device is receiving at that time. It also provides information about the rate of rotation, if available.

Examples

function handleMotionEvent(event) {

    var x = event.accelerationIncludingGravity.x;
    var y = event.accelerationIncludingGravity.y;
    var z = event.accelerationIncludingGravity.z;

    // Do something awesome.
}

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

Other properties

Property Type Description
acceleration Read only DeviceAcceleration The acceleration of the device. This value has taken into account the effect of gravity and removed it from the figures. This value may not exist if the hardware doesn't know how to remove gravity from the acceleration data.
accelerationIncludingGravity Read only DeviceAcceleration The acceleration of the device. This value includes the effect of gravity, and may be the only value available on devices that don't have a gyroscope to allow them to properly remove gravity from the data.
interval Read only double The interval, in milliseconds, at which the DeviceMotionEvent is fired. The next event will be fired in approximately this amount of time.
rotationRate Read only DeviceRotationRate The rates of rotation of the device about all three axes.
