Presentation method of walking sensation based on walking behavior measurement with inertial sensors and pressure sensors

Abstract

In this paper, we give the way to make the sitting user feel the walking sensation, by using the walking sensation presenting device in which we put the data we got from measuring walking behavior. We measured walking behavior from the inertial sensors which we put on the insteps and waist of the pedestrian and pressure sensors on the bottoms of their feet. We get the data of back-&-forth movements of feet from the data of acceleration and directions from inertial sensors on insteps. In the same way, we get back-&-forth and leftand- right movements of the whole body from the sensor on back. Walking sensation presenting device has a chair for user to ride, which moves back-&- forth and right-&-left to presents walking body’s swing to user and the device which presents walking sensation to user’s lower limb. The device which presents walking sensation to user’s lower limb consists two parts. One part are the lower limb movement presenting board that moves back-&-forth to make user’s lower limbs do the same movement as the real walking. The other is the landing vibration presenting device. About 10% of amount of the whole body movement in real walking presents the best walking sensation to the user. About 20% of amount of the lower limb movement in real walking presents the best walking sensation to the user.
