 The latest advances in virtual reality, VR, have opened up a new era of possibilities for locomotion. Researchers and users alike are interested in understanding and experiencing the different techniques available. This paper reviews the literature on VR locomotion from 2014 to 2017, focusing on the interaction-related characteristics and the research topics that were addressed. It was found that most of the techniques used are based on physical interaction, using physical motion cues for navigation in VR environments. Additionally, a typology for VR locomotion was introduced, categorizing the techniques into four distinct types, motion-based, room-scale-based, controller-based, and teleportation-based.
