Indicates whether or not the device is providing orientation data absolutely (that is, in reference to the Earth's coordinate frame) or using some arbitrary frame determined by the device. See Orientation and motion data explained for details.
var absolute = instanceOfDeviceOrientationEvent.absolute;
On return, absolute is true if the orientation data in instanceOfDeviceOrientationEvent is provided as the difference between the Earth's coordinate frame and the device's coordinate frame, or false if the orientation data is being provided in reference to some arbitrary, device-determined coordinate frame.
