Visual Presentation Method for Paranormal Phenomena Through Binocular Rivalry Induced by Dichoptic Color Differences

Paranormal visual effects, such as spirits and miracles, are frequently depicted in visual games and media design. However, current methods do not express paranormal experiences as aspects of the sixth sense. We propose utilizing binocular rivalry to provide a new visual presentation method by displaying different images in each eye. In this study, we conducted two experiments. Experiment 1 assessed paranormal sensation, color perception controllability, and visual discomfort caused by mismatched colors in each eye in relation to color difference. Experiment 2 assessed our proposed visual presentation method in three application scenarios. The results indicate that our proposed method improves the visual experience of more realistic paranormal phenomena. Moreover, the sensation of paranormal activity, color perception controllability, and visual discomfort increase as the color difference between the colors displayed in the two eyes increases.
