DeviceOrientationEvent: absolute property Limited availability
The absolute
read-only property of the DeviceOrientationEvent
interface 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.
true
if the orientation data in instanceOfDeviceOrientationEvent
is provided as the difference between the Earth's coordinate frame and the device's coordinate frame
false
if the orientation data is being provided in reference to some arbitrary, device-determined coordinate frame.
