Abstract

The present study investigated whether visual discomfort was influenced by various individual differences, such as age, motion sickness susceptibility, interpupilary distance, and stereo acuity. The last three characteristics were measured individually. After watching 3D television programs for 80 minutes, participants answered the visual discomfort questionnaire, consisting of 5 different factors such as dizziness, eye pain, body ache, blurring vision. The university students and young adults had more discomfort than the participants in their 30s, 40s, or older. For the participants in their 20s, observers with higher scores in motion sickness susceptibility had more discomfort, but this tendency was weakened and disappeared as observers' age increased. With regard to interpupilary distance and stereo acuity, there was no difference in visual discomfort. The results were discussed in the context of convergence-accommodation conflict in 3D environment.
