To study the contribution of motor control and physiological feedback on the illusion of body ownership, I developed a Unity-based virtual reality system that allows the user to experience a virtual arm as his own.
In this system participants can see a virtual room and different representations of their virtual right hand through a head mounted display (HTC
Vive). Movements of their right hand are tracked with a LeapMotion sensor and physiological data (heartbeat) is recorded with a biosignal amplifier (by g.tec). The user’s heartbeat is then visualized as a subtle change of color of the virtual arm. Different combinations of visual, physiological and motor control feedback were compared in a user study.
