Comparing VR environments for seat selection in an opera theater

This study presents a comparison of the influence of different VR environments in the task of selecting a preferred seat in an opera theater. We used gaze-based raycasting and headsets in a low-cost head-mounted display (HMD) (GearVR); and a virtual wand, head tracking, and headsets in a CAVE, two somewhat opposing technologies in the spectrum of current VR systems. Visual rendering and the selection technique depend on the capabilities of each environment, whereas the sound is approximated in both environments. Results show that subjects can select similar seats but their decisions differ between both environments. The results obtained can be useful in guiding the development of future VR applications.
