devicemotion

L'evento devicemotion viene attivato a intervalli regolari e indica la quantità di forza fisica dell'accellezazione che il dispositivo riceve in quel dato momento. Fornisce inoltre informazioni circa la velocità di rotazione, se disponibili.

Informazioni Generali

Specifica: DeviceOrientation Event
Interfaccia: DeviceMotionEvent

Propietà

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.

Esempio

function handleMotionEvent(event) {

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

    // Fai qualcosa di maestoso.
}

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