Pendulum-type Force Presentation Device for Body Movement Instruction

Abstract

Various wearable devices for body movement instructions have been developed, however, the user sometimes suffers from a sense of restraint because of the structures of such devices. The authors proposed a novel instruction device with a pendulum that is attached to a tool, not to the user’s body, that is, this device does not restrain the user’s body movement. The center of gravity of the device that is attached to the tool translates by swinging the pendulum, and the user is expected to perceive a guiding force as if the user’s body is moved by an external guiding force. In this paper, the proposed device was applied to a calligraphy brush motion, and effective configurations of the device was explored through experiments.
