The Effect of Repeated Exposure to 3D Contents on Visual Discomfort

Due to the technological advance, people can enjoy 3D contents at home through 3D TV. This means that people can more easily access 3D contents nowdays. Considering the fact that visual discomfort caused from 3D environment was still unsolved, it is important to investigate the effect of repeated exposure to 3D contents on visual discomfort. In the present study, visual discomfort was measured through three different sessions with intervals of one and half months. In each session, while viewing 3D video clips for 80 minutes, participants were asked to press button whenever they felt discomfort. While the results showed a general tendency of decrease in button press, it was also found that there were individual differences. A rapid reduction in button press was found over repeated exposure in the results from participants with higher button press during the first session. A small increase in button press, however, was found in the results from participants with lower button press. Further studies should be needed to elucidate the characteristics of those potential risk individuals.
