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. We made a straight-line-course with step to measure the force acting on a 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 force acting on a joystick and vibration dose value (VDV). And we made sounds based on operation of skillful subject to investigate whether or not to listening these sounds promote efficient operation of the wheelchair.
