DeviceMotionEvent

The DeviceMotionEvent interface provides web developers with information about the speed of changes for the device's position and orientation.

Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.

Event DeviceMotionEvent

Constructor

DeviceMotionEvent()

Creates a new DeviceMotionEvent.

Instance properties

DeviceMotionEvent.acceleration Read only

An object giving the acceleration of the device on the three axis X, Y and Z. Acceleration is expressed in m/s².

DeviceMotionEvent.accelerationIncludingGravity Read 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.rotationRate Read 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 expressed in degrees per seconds.

DeviceMotionEvent.interval Read only

A number representing the interval of time, in milliseconds, at which data is obtained from the device.
