Retargeting Destinations of Passive Props for Enhancing Haptic Feedback in Virtual Reality

Abstract

Haptic retargeting is a commonly used technique to match passive props to virtual objects for adding tactile feedback in Virtual Reality (VR). However, researchers have mainly focused on single-hand retargeting and applied these techniques primarily for tasks of touching objects. In this work, we propose a novel retargeting solution for tasks of grabbing and placing objects in VR, called redirected placement (RP), which is applied when placing virtual objects. The key idea of this method is that when the user places the virtual object, it can enable the user to place the physical prop in a position that is easier to match with multiple other virtual objects, without being detected by the user.
