Head Gaze Target Selection for Redirected Interaction
Brandon J. Matthews, Ross Smith · 2019
Haptic interaction in virtual reality poses an ongoing research challenge as to how touch sensations are delivered in applications. A simple solution is to have matching physical and virtual counterparts, i.e. a physical switch provides perfect haptic feedback for a virtual reality switch with matching geometry. Redirection illusions take this further allowing many virtual objects to be mapped to one physical object. In many systems that utilise redirection the interaction sequence is predetermined. This prevents users selecting their own target and a reset action is also required to provide an origin for the redirection. This paper overcomes these limitations with a novel application of head gaze to enable users to determine their own sequence of interactions with a remapped physical-virtual interface. We also introduce a technique for providing an optimal mapping between physical and virtual components using multiple physical target to remove the reset action.
