Designing Visually Accessible Spaces: Rendering Three-Dimensional Spaces With Radiance

This group’s long-term goal is to provide tools to enable the design of safe environments for the mobility of people with impaired vision and to enhance safety for others, including the elderly, who may need to operate under low luminance and other visually challenging conditions. They conceive of a computer-based design tool in which complex, real-world environments (such as a hotel lobby, large classroom, or hospital reception area), could be simulated with sufficient accuracy to predict the visibility of key landmarks or obstacles (e.g., steps or benches) under a variety of natural and artificial lighting conditions. The research involves studies of human visual perception and also the rendering of photometrically accurate three-dimensional architectural spaces.
