Gesture through wheelchair control

This research develops a machines interface which has features of universal design and offers intuitive operations for complex task. We set the development of interface of electric wheelchair as a practical example, and proceed with this research. To improve quality of life for the elderly and disabled people, electric-powered wheelchairs (EPWs) have been rapidly deployed over the last 20 years. But up to now most of these electric powered wheelchairs are controlled by user's hands via joysticks and are very difficult for elderly and disabled users who have restricted limb movements. Therefore here we focus on the body motions which we humans have and try to realize a new type of interface which replaces conventional joysticks. In this work we refer gesture as basic form of nonverbal communication made with the hands. Naturalness' of expression, non encumbered interaction intuitiveness are all good reasons to replace current interface technology example keyboard, mouse, and joystick with more natural interfaces. Here common motions of our body are extracted and inputted to electric wheelchair interface these body motions are able to move the electric wheelchair in all directions. In this particular, this paper describes the design of prototype and results of basic research.
