6. The method of claim 1 , wherein the at least one subset of gesture angles further comprises a third subset of gesture angles, and wherein the third subset of gesture angles comprises a subdivision of the first subset of gesture angles that does not include any of the gesture angles comprising the second subset of gesture angles.
7. The method of claim 6 , wherein the recognizing the gesture is based further on comparing a third histogram representing a frequency of angles based on the third subset of gesture angles to a third model histogram representing a frequency of angles of a subdivision of gestures of the gesture model that does not include any gestures of the second model histogram.
