Study on human body motion interface

The joystick is the operation interface of electric wheelchair. The user needs to operate it in accordance with machine´s operational procedure specifications. Therefore the joystick is convenience operation system for the system side rather than the user side We focus on the body motions which humans have, and try to realize a new type of interface which replaces conventional joystick. There is a body motion which comes from instinctive adjustment functions to control changes of body shape caused by voluntary actions. We use this kind of motion as an interface and call it HBMI(Human Body Motion Interface). In this paper, we set a prototype based on the experiment for deriving a suitable measurement to detect human body motion. The evaluation of HBMI by using SD method is also presented.
