Plantar Haptic Display to Apply Distributed Ground Reaction Force

Abstract

The tactile sensation of the human foot is one of the most sensitive parts of the human skin sensation and is known to be used during various locomotion. Force-tactile presentation for the sole of the foot is considered to be effective in reproducing kinesthetic sensations. If it is possible to actually present the force sense faithfully, it is no longer necessary to learn to match the pseudo information presentation with his/her senses, so the performers have previously applied a vertical floor reaction force equivalent to that during exercise. However, there is no study about a plantar haptic display that can apply distributed ground reaction force on the four points of the sole as large as the force that human is applied during walking or running. We have developed a presentation device that applies to the bottom. In addition, we verified whether various motions can be identified only by the sole force sensation and confirmed.
