Purpose: This study investigated the factors for and impact of screen size on fatigue and cybersickness that can occur while watching virtual reality movies for a long time. Methods: The experiment was conducted among 60 adults aged 20-33 years old. Using the simulator sickness questionnaire, fatigue and cybersickness symptoms by screen size were compared and analyzed according to whether glasses were worn, sex, and age. Results: When the screen size was 70 degrees or 30 degrees, there was no significant difference in fatigue or cybersickness. Additionally, differences according to screen size were analyzed by subdividing whether glasses were worn, sex, and age. There were significant differences in general discomfort, eye fatigue, and nausea regardless of the use of glasses. According to sex, headaches were more frequent in women than in men. The difference according to age was greater in those aged over 24 years in terms of stability fatigue and general discomfort. Conclusions: Most subjects did not feel the difference in fatigue according to the screen size. therefore, it seems appropriate to watch a screen large enough to feel a sense of presence and immersion. However, among three factors, namely, age, sex, and wearing glasses, we found that wearing glasses was the most uncomfortable aspect, and differences according to age and sex were observed. Therefore, setting an appropriate screen size for viewing is recommended.
