Abstract
ABSTRACT It is well known that some viewers experience visual discomfo rt when looking at stereoscopic displays. The disparity is one of the key factors that affect visual comfort in 3D contents, and there is a comfortable disparity range for a person. In this paper, we explore the comfort disparity, which correlates with the optimal viewing distance, as a function of the maximum disparity for an individual. Firstly, the individual maximum disparities of 14 subjects were measured. Then the subjects were asked to rate the comfort scores for a 3D video sequence with different disparity, to evaluate the individual comfort disparity. The results show that as the individual maximum disparity increased, the corresponding comfort disparity increased, and we foun d a correlation coefficient of r=0.946. The average ratio between the comfort disparity and the maximum disparity was approximately 0.72, and this ratio can be used for one to determine the optimal 3D viewing distance by a rapid method. Keywords: visual comfort, 3D displays, maximum disparity, comfort disparity, viewing distance
