It's doubtful you can literally tell if the person has turned around. I think you're trying to infer that, by assuming the person is holding the device a certain way in relation to his or her body..
Perhaps by that assumption, the device moves in a 360° arc through space, not on an axis intersecting the device (simple bearing). It should be possible to track the position of the device through the arc via the accelerometer and infer the body movement you are trying to figure out.
