User-centric classification of virtual reality locomotion

Traveling in a virtual world, while confined in the real world requires a virtual reality locomotion (VRL) method. VRL remains an issue because of three fundamental challenges, sickness, presence, and fatigue. We propose a User-Centric Classification (UCC) of VRL methods based on a method's ability to address these challenges. UCC provides a framework to discuss and compare different VRL methods and to examine performance trade-offs. We designed and implemented a testbed to study several VRL methods, and initial results demonstrated the effectiveness of the UCC framework [1].
