Solving Rendering Issues in Realistic 3D Immersion for Visual Rehabilitation

When a person becomes visually impaired, intensive rehabilitation is required to learn the skills necessary to accurately interpret the sensory cues. 3D virtual immersion (3D VI) can provide a safe and rich world for rehabilitation by rendering a complex environment. 3D VI can stage challenges that can be faced with less stress than the real outdoor world. In order for 3D VI to be used efficiently, the visual rendering for people with low vision and the audio for both the blind and people with low vision must be as realistic as possible. Building a 3D environment at low cost imposes constraints both on the installation and the technical aspects. This paper describes our current work to solve projections issues for a realistic rendering when images are not aligned and deformed.
