Relationship between age differences and display parameters on visual comfort for autostereoscopic display

摘要

In order to investigate the age differences for viewing autostereoscopic display, we conduct a 3×3×3×4 mixed design with repeated measurement experiment by using three-dimensional (3D) video clips. Visual comfort is compared between four age groups with a questionnaire. Results of subjective evaluation are compared through the chi-square test to check if there is a statistical significance between groups with respect to the distribution of number and proportion according to five levels of visual comfort. Then we examine age differences of visual comfort under three key display parameters including crosstalk, ambient illumination, and disparity. The results indicate that the degree of comfort varies considerably among age groups as the parameters of the display system change. Although the seniors feel most discomfort and the children get best experience in general, there is no statistical difference among the subjects when the ambient illumination is medium or disparity is large. So, it is necessary to take account of the age differences in designing 3D display parameters for enhancing visual comfort.
