Systematic Design Space Exploration of Discrete Virtual Rotations in VR

Abstract
Continuous virtual rotation is likely one of the biggest contributors to cybersickness, while simultaneously being necessary for many VR scenarios where the user, for instance, is sitting in a bus, at an office desk, or on a couch and therefore, limited in physical body rotation. A possible solution is discrete virtual rotation, such as already broadly accepted in translational movements (teleportation). In this work, we want to help increase the knowledge about discrete virtual rotations. We classify existing work and systematically investigate the two dimensionstarget(rotation)acquisition(selectionvs. directional)and body-based (yes vs. no) regarding their impact on the performance in a naive and a primed rotational search task, spatial orientation, and usability. We do find the novel virtual rotation selection most successful in both search tasks and no difference in the factor bodybased on spatial orientation.
