In this paper, we quantified the gloss perception by using binocular stereoscopic display. In our experiment, we evaluated gloss perception changing the disparity angle of surface and highlight to investigate the relationship between glossy appearance and the disparity angle. The magnitude estimation method is used to evaluate the sensibility of gloss appearance subjectively. As the result, the score of subjective evaluation on stereo display is stronger than on flat display, within the disparity angle range that is depth perceptible, and the score on stereo display and on flat display is same without the range. Additionally, we found that glossy contrast correlated highly with evaluation score regardless of the disparity angle and display method.
