Abstract
In this paper, a structure determination method for wearable devices mounted on multiple joints of body parts are proposed. Motion of back part of the upper half body is more complex than that of simple joint part such as leg, arm and so on. There are no structure determination methods suitable for multiple body parts. Therefore, the motions on the back parts are captured through a sensor (Kinect for Windows V2) and analyzed based on relationship between markers mounted on back. The link parts and joint parts are distinguished based on standard deviation of relative distances of markers.
