Abstract

Methods of recognition were compared in this paper for characteristic signals of hand waving gestures. Confused motions between “beckoning” and “waving away” were distinguished by characteristic signal mixing with a gravity motion and an area variation in the image of a moving hand. Their dynamic gestures are recognized by DP matching, wave difference, and other methods. Results were as follows: (1) taking the difference of a hand waving trajectory into account, the recognition ratio rose to more than 92.3%, (2) but by using categorized vectors to search for the same vectors in an input waving motion, it was made clear that the missed-recognition ratio between “beckoning” and “waving away” was suppressed.
