Abstract
Methods and apparatuses of the present disclosure are presented for recognizing a gesture of a gesture object in a plurality of recorded data objects, with the recorded data objects being recorded over time. In some embodiments, a method includes computing at least one set of gesture angles using the plurality of recorded data objects, wherein each of the gesture angles in the at least one set comprises an angle measurement between two positions of the gesture object, the two positions recorded in successive data objects in the plurality of recorded data objects, and recognizing the gesture based on the at least one set of gesture angles. In some embodiments, the method includes recognizing the gesture is based further on comparing the at least one set of gesture angles to a gesture model.
