An immersive Visuo-Haptic VR environment with pseudo-haptic effects on perceived stiffness

Abstract

In this presentation, we describe an immersive visuo-tactile VR system which presents tunable subjective hardness of virtual objects by employing the pseudo-haptic effects. Our system supposes that users put on an HMD and a glove which contains a mechanical structure that presents constraining force to his or her fingers in pinching virtual objects. The system visually displays a re-rendered virtual hand pinching deformed objects with its finger flexion magnified or suppressed graphically, for arousing the pseudo-haptic effect. We expect this method to be effective in creating mobile wearable tactile systems that are correlated to personal VR systems in home applications.
