Abstract
Recently, some developments for a high performance wheelchair have been proposed. For example, the hand-free control system of wheelchair is one of the useful function in the case that operator wants to do the handwork. In this study, we propose an intelligent wheelchair maneuvered by operator’s posture change. When we drive a car or motorcycle, we intend to incline our body to the traveling direction. So, the amount of posture change involves the operator’s intention to move with expecting direction and velocity. We ar- ranged the pressure-sensitive mat on the back of wheelchair in order to measure of the amount of posture change, and also developed a control signal generating system by the use of pressure distribution data. In this report, we describe a concrete composition of the control system and results of evaluation experiment.
