Analysis of pointing motions by introducing a joint model for supporting embodied large-surface presentation

The importance of utilizing the advantages of embodiment in presentation has often been pointed out. In recent years, because of the increase in the size of screens and displays, the realization of a large-surface presentation by arranging many screens and displays on the wall of a room is expected. In this study, we precisely analyzed pointing motions by introducing a joint model and in freestyle movement. First, we introduced a joint model and proposed a new model for the calculation of a joint center. Next, we calculated the joint centers of a shoulder, an elbow, and a wrist. Then, we performed a pointing experiment in front of a large-surface and analyzed the pointing motions.
