The Effects of Natural Landscape Images Using Projector Display on Human Psychophysiology in Rest Space

We aim to create a comfortable environment with low fatigue by investigating the psychological and physiological effects of projected natural landscape images on individuals in rest areas. Our experiment primarily focuses on image type and considers greenery view rate, dynamic/static nature, and view as key parameters. Results indicate the absence of visual fatigue at critical flicker fusion fluctuation rates of 3 or less. Psychological evaluations reveal that "sense of healing" and "calmness" decrease with abrupt image movements or minimal greenery. Further, the sense of oppression increased in poorly lit environments and decreased in well-lit ones. Our findings suggest that the projection of natural landscape images can help create comfortable rest areas when implemented under appropriate conditions.
