Study on Attention Distribution for Supernumerary Limbs in Dual task

-Evaluation about Perception Verification Accuracy of Proprioceptive Sensation for Supernumerary Limbs Using Vibration Feedback-

Abstract

Haptic Feedback Belt is the device which notice the supernumerary arm’s posture which is put on the arm’s user as vibration feedback. In this paper, we examine whether participants can perceive the supernumerary arm’s posture which leaves them with Haptic Feedback Belt on Dual task. Experiment was conducted to compare perception accuracy when they accomplished the recognizing task of supernumerary arm’s posture on Single task situation and Dual task situation. On Single task situation, they accomplished only the recognizing task. Then, on Dual task situation, they accomplished the recognizing task with pouring water into beakers with their own body. The results suggested that they can perceive the posture on Dual task situation as exactly as on Single task situation.
