In this paper, we propose a wearable sensor system that measures an angle of an elbow and position tapped by finger using bone-conducted sound. Our system consists of two microphones and a speaker, and they are attached on forearm. A novelty of this paper is to use active sensing for measuring an angle of an elbow. In this paper, active sensing means to emit sounds to a bone, and a microphone receives the sounds reflected at the elbow. The reflection of sound depends on the angle of elbow. Since frequencies of bone-conducted sound by tapping and from the speaker are different, these proposed techniques can be used simultaneously. We confirmed the feasibility of proposed system through experiments.
