Some recognition methods were compared with in this paper for characteristic signals of hand waving gestures. Confused motions between "beck" and "driving away" were distinguished by each characteristic signal, mixing with a gravity motion and an area variation of the image of a moving hand. Therefore their dynamic gestures were able to recognize by methods of DP matching, wave difference and others. The results are the following : (1) taking the difference of a hand waving trajectory, the recognition ratio rose to more than 92.3%, (2) DP matching was not so available in the formless motions, (3) but by using some categorized vectors to search the same vectors in a trajectory, it was cleared that the miss-recognition between "beck" and "driving away" is sup-pressed.
