Device Orientation

The device orientation is represented by three angles - alpha, beta and gamma.

Alpha angle rotates around the Z axis. It is between 0 and 360 degrees. It is 0 when the top of the device is pointed towards north.

Beta angle rotates around the X axis. It is between -180 and 180 degrees. It is 0 when the device is parallel to earrh's surface.

Gamma angle rotates around the Y axis. It is between -90 and 90 degrees. It is 0 when the device is parallel to the earth's surface.
