Outline of Final Research Achievements

Using electromyography and electroencephalography, we evaluated the physiological response caused by the occurrence of Pseudo-Haptics in a relatively wide area. In addition, we used a psychophysical method to evaluate the accuracy of Pseudo-Haptics perception, and compared it with these physiological signals to investigate the quantitative evaluation of the occurrence condition of Pseudo-Haptics. With the presentation of Pseudo-Haptics by imparting resistance-sensitive perturbation, the muscle activity increased and the proportion of β and γ waves in the EEG tended to increase. The results suggest that we could capture the changes in mental state such as stress and tension associated with the occurrence of Pseudo-Haptics.

Academic Significance and Societal Importance of the Research Achievements

Pseudo-Haptics（疑似力触覚）と呼ばれる錯覚現象を利用することで，モータなどの機械的な外部動力を使用せずに，人に力を感じさせることができる．このとき，条件によっては筋活動量が増加する現象が確認されており，この現象を利用することで，シンプルで安全な新しいエクササイズシステムの開発が期待できる．本研究は，筋活動が活性化する現象が起きる条件について特定するための方法を、検討するためのものである．
