Effect of deceleration on fall sensation for development of lower limb force feedback device

Abstract

The purpose of this study is to investigate the effects on human fall sensation when a VR fall sensation presentation device is used to decelerate the device during descent. A questionnaire survey using VAS was conducted to evaluate the effects of acceleration and deceleration on the sensation of falling. A questionnaire using VAS was used to evaluate the sensation of falling and the sense of reality depending on the amount of acceleration and the amount of deceleration. The results suggest that, within the range of acceleration used in this experiment, the deceleration of the device does not significantly impair the sense of falling and the sense of reality.
