Geometry deformation for reducing cybersickness in VR

Abstract

Virtual reality (VR) technologies became more and more widespread for a couple of years as they got more and more mature. The accessibility to VR highly increased thanks to recent low-cost commercial VR head mounted display systems and easy-to-use development toolkits. One important and well-studied human perception issue is related to motion sickness or cybersickness. In this paper we are dealing with case when users feel a visually induced induced self-motion that are not felt through their vestibular systems. This incoherent movement perception provokes cybersickness to the users. To tackle this issue, we present in this paper a novel method to reduce cybersickness through reducing visually induced self-motion by processing geometrically the virtual scene while navigating. The first prototype of geometry deformation applied on virtual building appearing in the peripheral vision of user has been implemented and experimented. The feedback from the experiment participants shows that the visually induced self-motion is reduced and the navigation quality and presence level are guaranteed.
