| Outline of Final Research Achievements |
In this study, we established a method to create an experience of illusory body movement without using any physical movement of the body or motor commands to muscles. The method can modulate bodily sensations through sensory interaction and adjusts gains with sensory information generated by actual body movement. We also proposed an objective index for the magnitude of the effect of the pseudo-movement generated by the presentation of vibration stimuli to the soles using objective indices such as the reduction of reaction time due to interactions between senses in the peripersonal space near the body. We compared the pseudo-walking sensation produced by vertical swaying and turning with a motion platform and the rating of VR sickness.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果はこれまで主観的評定にとどまっていた疑似歩行感覚を，客観的指標である反応時間で評価できる可能性を示したものである．臨場感の高いVR システムを構築する際に，臨場感やリアリティが高まれば，主観的な評定では天井効果や個人差の影響によって明確な評価を困難になってしまうため，本研究の成果のように客観的な指標でも評価することができれば，さまざまな側面から最適な感覚刺激を設計する手がかりとなりうる．また，モーションプラットフォームを用いて受動的な状況で擬似的な身体感覚を生成する研究成果は，運動機能障害を有するユーザにも多様な移動感を生成する可能性を提供するものである．
