Current research in vision accessibility for virtual reality does not explore the unique means of interaction afforded by light perception vision (i.e., blindness with only remaining light perception). We present ContrastVR, a high-contrast filter designed to optimize virtual environments for people with light perception vision. A user can customize their view by adjusting levels of brightness and detail of the overall environment, as well as the shininess and gamma of textures. They can also choose between outline and planar models of the environment, and toggle an orientation lightsource and depth map. ContrastVR also dynamically reduces visual noise by adjusting levels of detail based on the relative distance of environment elements.

With help from The Carroll Center for the Blind, we are planning to evaluate how participants with light perception vision perceive, play, and enjoy virtual reality environments with ContrastVR.
