Abstract With the promotion of technology, 3D displays not only offer high-end video and sound qualities, but also provide largerthan-life viewing experiences. Twenty-five participants were recruited to investigate the effect of video type (horror, action, and comedy), display technique (2D, 3D), and ambient illumination (a dark room, 1500 lux) on saccade length, number of fixations, Simulator Sickness Questionnaire (SSQ), iGroup Presence Questionnaire (IPQ), and change of heart rate. The results showed that video type was significant on SSQ and IPQ, where horror videos showed the greatest effects on SSQ and IPQ. In addition, display technique was significant on number of fixations, SSQ, IPQ, and change of heart rate, where the 3D technique resulted in a higher number of fixations, SSQ, IPQ, and change of heart rate. Furthermore, ambient illumination was significant on number of fixations, IPQ, and change of heart rate, where a dark room led to a higher number of fixations, IPQ, and change of heart rate. The main contribution of this study is that it offers suggestions for choosing the appropriate video type, display technique, and ambient illumination when watching 3D movies—namely, for 3D film manufacturers, using horror videos in a dark environment brings greater realness and presence, but also results in higher visual fatigue and change of heart rate.

1 Introduction In the past, good sound effects and image quality were equipped with 2D displays. As technology developed, 3D displays not only offer high-quality images and videos, but also provide larger-than-life viewing experiences. Barfield and Rosenberg (1995) showed that 3D displays can shorten response time while improving accuracy for depth judgement. Kalich et al. (2003) also indicated that a broader vision is provided by 3D displays. More recently, Liu and Uang (2016) and Liu et al. (2019) used a 3D technique to simulate a 3D virtual store and a 3D virtual art gallery in order to evaluate the elderly’s presence and spatial identification. Lin and Chang (2017) and Lin and Chen (2019) concluded that, compared to 2D displays, 3D displays can provide greater presence. However, there are still several drawbacks * Po‑Hung Lin [email protected] 1

when watching 3D images. Lin and Jhang (2014) found that 3D interfaces in autostereoscopic mobile phones induced more fatigue and less usability than 2D interfaces did. Lin and Chang (2017) and Lin and Chen (2019) showed that 3D techniques induce higher visual fatigue in 3D games. For applications in mo
