Visualization of Disability Glare Due to Veiling Luminance
Paper in proceeding, 2015

We present a simulation method to evaluate and visualize disability glare problems. Mathematical calculations of visual degradations due to optical imperfections in the eye are performed on luminance photos of scenes and the result is visualized. The method was evaluated in three indoor and outdoor cases where different visual aspects on disability glare were studied. Overall, the simulations predicted problem areas in the scenes to a large extent. The method was also applied in a light rendered 3D-model and gave indications for improvements of the light setting. Aspects on improving environmental planning by better understanding of human vision are discussed.
