Abstract

<p>人間の安定性感覚は人間の姿勢維持に関わる重要な感覚であり,安定性感覚を提示することができればVR体験のリアリティ向上などに繋がると考えられる.本研究では,安定性の指標の一つである重心投影点を再現するため,他者の足裏反力を再現する装置と重心投影点回答システムを用いて,他者の足裏反力を提示された際に,再現した足裏反力から推定した重心投影点を確認する実験を行い,実際の足裏反力を提示した場合は2 cmの精度で重心投影点推定が可能であり,0.1倍した足裏反力を提示した場合には推定が困難であることを確認した.</p>

<p>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.</p>
