An effective FoV restriction approach to mitigate VR sickness on mobile devices

It has been noted that restricting field of view (FoV) is effective to mitigate virtual reality (VR) sickness, but it is prone to reduce the immersiveness. We propose an effective FoV restriction approach to mitigate VR sickness on mobile devices. The proposed approach includes a practical and reliable method for measuring VR sickness and a method of effectively limiting the FoV on mobile VR devices. Experimental result shows that the proposed method reduces VR sickness by 31.4%. The method was successfully applied to a VR application.
