Abstract— To evaluate the relationship between visual angle and the sense of presence for wide displays, two experiments were conducted in which the visual angle (ranging from 30 to 100°) was manipulated as a between‐ and within‐subjects factor, respectively. Two‐hundred subjects participated in both experiments. In the within‐subjects evaluation, presence scores increased as the visual angle widened, while those in the between‐subjects evaluation did not increase significantly for a wide visual angle. It can be concluded that “contrast effect,” i.e., a bias caused by comparing different visual angles, greatly affects the ratings of sense of presence.
