Paper Abstract
"In virtual reality (VR) experiences, discordance between visual and somatic sensation reduces a user’s immersive experience. To address this problem, we introduced somatic sensation using illusory force induced by tendon electrical stimulation (TES). The effect of TES applied to the tibialis anterior muscle tendon (TA) and Achilles’ tendon (AC) on force sensation and center of pressure (CoP) in standing position was investigated. Result suggests that application of TES to TA and AC induces force sensation to evoke body sway in the backward and forward direction respectively, while effects on CoP appear to be contradicted to our hypothesis. According to the descriptions of induced sensation of body tilt obtained from questionnaires, this technique is a promising way to present information of ground in VR."
