Operation of the auto wheelchair using movement of knee and toe

Abstract

This paper proposed a new intuitive interface based on lower limbs exercises. Here, we considered that the center of gravity on the sole of the foot was observed to reflect on the operation of the equipment by using the slippers, whose sole shape was curved just like a cradle. The developed foot interface was applied to the control of the auto wheelchair. The operation mode was composed of three states, forward and backward mode, diagonal mode, and turn mode, and these were changed by the shift in center of gravity movement to the heel. Each operation was carried out by the shift in center of gravity movement to the heel and the toe.
