Abstract
We have proposed a system that supports the proficient operation of an electric wheelchair with acoustic information. The audio system provides the electric wheelchair user with acoustic information with the aim of conferring an intuitive feeling of how the wheelchair is operated. To investigate whether or not this audio system promotes efficient operation of the wheelchair, we constructed a sensing system for analyzing the movement of the electric wheelchair. We made a straight-line-course with step to measure the joystick and motion behavior of an electric wheelchair. We repeated a running test of the electric wheelchair for the same test subjects until they improve operation skill. We thereby demonstrated that there is a relationship between the acting on a joystick and vibration. We also investigated whether or not to listening sounds promotes efficient operation of the wheelchair.
