Properties
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.
The alpha read-only property of the DeviceOrientationEvent interface returns the rotation of the device around the Z axis; that is, the number of degrees by which the device is being twisted around the center of the screen. See Orientation and motion data explained for details.
The beta read-only property of the DeviceOrientationEvent interface returns the rotation of the device around the X axis; that is, the number of degrees, ranged between -180 and 180, by which the device is tipped forward or backward. See Orientation and motion data explained for details.
The gamma read-only property of the DeviceOrientationEvent interface returns the rotation of the device around the Y axis; that is, the number of degrees, ranged between -90 and 90, by which the device is tilted left or right. See Orientation and motion data explained for details.
