Abstract
Hand gestures can express various kinds of information; however, exiting techniques have problems for practical use such as environmental limitations and obstructions to natural gesture. To address these problems we have developed a wrist contour measurement device that recognizes hand shape and pronation angle in the previous work. The previous paper indicates that it is necessary to increase the number of recognizable hand motions to realize a high-usability screen operation. This paper reports the trial of simultaneous recognition of hand shape and wrist flexion state. We observe wrist contour and make clear the phenomenon, design features, and construct a recognizer. The simultaneous recognition rate of four hand shapes and nine wrist flexion states achieved in this research is 75.5%.
