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.

Properties
| Property | Type | Description |
|---|---|---|
target Read only |
EventTarget |
The event target (the topmost target in the DOM tree). |
type Read only |
DOMString |
The type of event. |
bubbles Read only |
Boolean |
Whether the event normally bubbles or not |
cancelable Read only |
Boolean |
Whether the event is cancellable or not? |
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 |
DeviceAcceleration Read only | 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. |
Example
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);
