This research studied the effect of cross-talk and three-dimensional (3-D) cues upon viewers’ visual fatigue and image quality evaluation in both mirror-type 3-D displays and barrier-type autostereoscopic displays. The experiment included three parts. First, the effect of system cross-talk, shadow, and linear perspective of 3-D pictures, in a mirror-type 3-D display, was discussed. Second, an acceptable threshold level of system cross-talk was sought. Third, the fitting system cross-talk level, in barrier-type autostereoscopic displays corresponding to that in mirror-type 3-D displays, was determined. The results showed that system cross-talk, shadow, and linear perspective, which were chosen from the various depth cues to study in this research, were significantly affecting image quality evaluation when watching 3-D displays. The acceptable system cross-talk level in mirror-type 3-D displays ranged from 18% to 23%. The content of a 3-D picture was critical to influence perceived image quality of autostereoscopic displays. In this experiment, viewers did not get visual fatigue and visual discomfort when watching 3-D pictures for 10 min. Moreover, experts ranked higher than novices in evaluating 3-D image quality. The outcomes of this study could be served as a reference for the design of 3-D displays. As for future work, an interesting direction to explore will be the effect of the dynamic 3-D films on viewing experience.
When people watch 3D-Ready TV, the display luminance as well as the ambient illuminace is important factors for
image quality and physiological comfort.
In this research, a human factors experiment on a stereoscopic display was conducted. The result showed that display
luminance affected subjective comfort evaluation and image quality evaluation. The effect of ambient illuminance also
influenced objective asthenopia index (CFF), subjective comfort evaluation and viewers' image quality evaluation of
watching 3D static pictures. However, the main effects of display luminance, ambient illuminance, and their interaction
effect were not significant on objective physiological measurement (HRV). Among the six combination levels of display
luminance and ambient illuminance, viewers felt more comfortable and got the best image quality in the high levels of
display luminance and ambient illuminance.
The outcome of the experiment is expected to find out the optimal display luminance and ambient illuminance
combination level for designers' guidelines and users' references as viewing 3D displays.
