36.1: Visual Comfort and Viewing Time of S3D Content on Mobile Devices

The authors conducted an experiment that examined the relationship between visual comfort and an individual observer's near phoria in terms of the length of time spent viewing 3D content on a mobile device. Two experimental parameters were used: the position of the stereo video images (in front of the screen and behind the screen) and the time for which the images were viewed (three, nine, and fifteen minutes). The results showed that observers with a higher degree of exophoria tend to prefer stereo images that are presented behind the screen when the viewing time is short.
