Embodied Interaction using Non-Planar Projections in Immersive Virtual Reality

In this paper we evaluate the use of non-planar projections as a means to increase the Field of View (FoV) in embodied Virtual Reality (VR). Our main goal is to bring the virtual body into the user’s FoV and to understand how this affects the virtual body/environment relation and quality of interaction. Subjects wore a Head Mounted Display (HMD) and were instructed to perform a selection and docking task while using either Perspective ( ≈ 106º vertical FoV), Hammer or Equirectangular ( ≈ 180º vertical FoV for both) projection. The increased FoV allowed for a shorter search time as well as less head movements. However, quality of interaction was generally inferior, requiring more time to dock, increasing docking error and producing more body/environment collisions. We also assessed cybersickness and the sense of embodiment toward the virtual body through questionnaires, for which the difference between projections seemed to be less pronounced.
