Psychophysical Influence on Perception of Pain Stimulus by Visual Superimposition(<Special Issue>Mixed Reality)

Abstract

Our study centers on providing tactile feedback in Mixed Reality (MR) environment. While most studies focus on the use of vibration and temperature to provide tactile feedback, vibration and temperature are not the only sensations a human can perceive. In this study, we focus on the psychophysical influence of MR visual stimulation on pain sensation. We conducted an experiment where we induce pain on the subject's forearm and display visual stimulation on a different position than where we induced the pain. We found out that the position where the subjects perceived pain, differs from the actual position according to the displayed visual stimulation.
