A myoelectric hand is a prosthetic hand that reproduces both the appearance and function of the hand. However, due to various factors, the myoelectric prosthetic hand is currently perceived as different from the actual hand, and it cannot be said to be embodied. As with rubber hand illusion, there is a possibility that myoelectric prosthetic hands can be embodied by adding various sensory feedback, but there are many unknowns in the field of myoelectric prosthetics. In this study, I investigated the effects of visual, tactile, and deep sensory feedback on the embodiment of myoelectric prosthetic hands by means of a questionnaire. The results showed that visual feedback had the strongest influence on embodiment compared to the others, with smaller movement delays resulting in stronger embodiment. Tactile feedback promoted embodiment. Deep sensory feedback reduced the sense of ownership but increased the sense of agency.
