Turn Your Head Half Round: VR Rotation Techniques for Situations With Physically Limited Turning Angle
Rotational tracking enables Virtual Reality (VR) users to
turn their head around freely 360° while looking around the
environment. However, there are situations when physical
head rotation is only possible for not more than a certain
range, e. g., when the user sits in a bus or plane while she is
wearing a VR headset. For these situations, rotation gains
were introduced to decouple virtual and real rotations. We
present two more techniques that allow 360° virtual turning
in a physically limited space: Dynamic Rotation Gains and
Scrolling. We conducted an experiment to compare those
three rotation techniques and a baseline condition regarding
VR sickness, spatial orientation, and usability. We found a
significant underestimation of rotation angles for the dynamic rotation gains which might mean that this technique
is more subtle than others. Furthermore, usability was higher
and VR sickness lower for the dynamic rotation gains while
scrolling caused the highest VR sickness. Finally, we conducted a confirmatory study to prove the applicability of
dynamic rotation gains in an actual VR experience and got
promising feedback.
