Survey on the Ability to Estimate the Position of the Projected Center of Gravity Under Different Scale of Sole Reaction Force Presentation

Abstract

Human stability is an important sense that relates to human posture. If it can be presented the stability sense, it will improve the reality of virtual reality experience. In this study, in order to reproduce the projected center of gravity, which is one of the indices of stability, we conducted experiments to confirm the projected center of gravity from the replicated plantar reaction force when presented with the other’s plantar reaction force. A device to reproduce the other’s plantar reaction force and the center of gravity projection response system were used. We confirmed the projected center of gravity with an accuracy of 2 cm. Therefore, it is possible to estimate the center of gravity projection point and difficult to estimate when the foot reaction force was multiplied by 0.1.
