Sense of Agency in Drum Trainer With Multiple Sensation Feedback

摘要

Passive motion is often used in physical skill transfer. This study investigated sense of agency during virtual drumming with visual, vibrotactile and auditory sensation feedback in three types of forearm motion: voluntary, passive and imagined. Agency judgement showed that visual, vibrotactile and auditory feedback contributed to sense of agency around 25 %- 45 % depending on the type of forearm motion. Motor command in voluntary motion contributed about 35 %, while proprioception in passive motion did about 25 %. Threse results suggested that multiple sensation feedback contributed to generate sense of agency.
