| Project | Peripheral Visual Perception with a Curved Perspective B.Sc semester project, IIG laboratory EPFL |
| Description | Spherical projections techniques have the potential to increase thefield of view in a virtual environment without introducing has manydistortion as with a classical pinhole camera. Specifically in anenvironment explored with head mounted devices, the current stateof the art of those device doesn't allow for a field of view as wide asthe human eyes one. We try different methods of projection toexpend the field of view that one gets in such an environment, and wetry to estimate the advantages and drawbacks of such methods. Wefocus on our research on three area that should matter to the enduser: the performance difference in realizing typical tasks, the well-being of a subject exploring this environment – we try to measure thediscomfort that such techniques could introduce - and the feeling ofembodiment in a virtual avatar. |
