Influence of Virtual Reality Setup on Locomotion Technique Usage during Navigation with Walking, Steering and Teleportation

Abstract

The evaluations of Locomotion Techniques (LTs) provide information regarding the advantages and shortcomings of LTs for navigating in Virtual Reality (VR). While the primary approach is to assess the LTs separately (e.g., comparing walking versus steering versus teleportation), little is known about how LTs can be used simultaneously (i.e., how users navigate when several options are offered), especially in different VR setups. This paper aimed to investigate the influence of real and virtual environment size on LT usage during VR navigation for the first time. We conducted a user study (n=24), where participants had to explore a virtual garden and pick up mushrooms. Participants could choose to walk, steer, or teleport. We varied the size of the virtual environment as well as the size of the user’s physical workspace. We found that users’ LT usage depends on the VR setup. For instance, they tend to do more displacements with teleportation (which was users’ favorite technique overall) but would rather walk or steer when the size of the virtual environment is the same as the workspace. This work contributes to understanding user behavior in VR, particularly regarding LT usage, which tends to be an overlooked topic.
