Examining 3-D Technologies in Laptop Displays

As 3-D content migrates to the laptop, it is important to understand if customers can perceive quality differences between the 3-D technologies and to know if they feel any discomfort with close-up viewing of 3-D displays. In this study, we compared the quality and viewing comfort of active, passive, and autostereoscopic (glasses-free) 3-D displays. We found that participants were able to discern differences in 3-D quality and comfort on laptop computer displays in realistic viewing conditions within a short period. Although the active and passive displays were comparable, the autostereoscopic display was rated lower in quality and viewing comfort.
