In this study, we investigate the difference of visual perception about glossy appearance between on a flat display and on a stereo display. Appearance is an optical phenomenon reflected from object, and the glossy appearance is most important characteristic that shows its shape profile and/or material of object, since it changes dramatically depending on the view-points. For this appearance, Pellacini et al. tried to verify the human visual perception by using magnitude estimation method. And they modeled the relationships between the perception and physical parameters, such as specular and diffuse reflection. They tried to reproduce the appearance only on flat display. However, it is also important to include the depth information for a realistic glossy appearance. Therefore, we evaluated the perception of glossy appearance with a stereo display using magnitude estimation method, and compare the relationship of specular and diffuse reflection between the results obtained with a flat display and those with a stereo display. With isotropic version of Ward's light reflection model, we rendered 9 images for evaluation. The images were presented on a stereo display, in a random order. Five subjects who had normal stereo vision participated as a subject, and they were asked to evaluate a number to each stimulus, which indicated the apparent magnitude of the perceptual attribute. From the experimental results, it was shown that the glossy perception on a stereo display was more impressive in comparison with those on a flat display.
