To assess the changes in subjective fatigue and pupil diameters while watching two different videos in different viewing conditions such as the screen luminosity and the display forms. A total of 108 subjects were participated in this study. The pupil diameter of the participants was measured by an eye tracker while the subjects watched one of the two different videos in different viewing conditions. The subjective fatigue of each subject was measured by a questionnaire conducted before and after watching the videos. The relative effects of the viewing conditions on the pupil diameters showed significant correlations in both screen luminosity and display forms (pâ¯<â¯0.05). The levels of subjective fatigue increased after watching the videos, compared to those before watching them, and the young subjects significantly felt more tired (pâ¯<â¯0.05). Changes in the subjective fatigue and pupil diameters during watching videos on LED TVs were different according to the display forms, the screen luminosity and videos. However, the pupil diameters decreased with a pattern of regression in the linear and third-order polynomial expressions in process of viewing time. The present study suggests a further study with a detailed analysis is needed to prove these findings.
