Abstract

A strongly perceived sense of ownership (SoO) of an amputees' device paired with agency leads to aspects of embodiment for that device. The purpose of this research was to explore the potentiation of SoO through proprioception while using a tactile feedback modality. In a sensory interference task, participants responded to vibrotactile stimulation presented to their index finger and thumb while experiencing incongruent and congruent visual feedback, with and without proprioceptive feedback. We found that participants' crossmodal congruency effect (CCE) scores for the vibrotactile feedback were higher when experiencing proprioceptive feedback that aligned with the movement of the virtual hand on the screen. Providing prosthesis users with more intuitive and useful sensory feedback may increase their perceived SoO of their device. When paired with agency, this can lead to improving their control performance and device acceptance.
