Abstract

Although natural light is essential for human health and well-being, the potential effects of different brightness levels of light on the visual perception of forests have not been discussed. Using controlled eye-tracking experiments, this study explored the impact of seven simulated natural brightness levels, from the darkest to the brightest, on the visual perception of 118 participants in a virtual reality (VR) forest environment. One of the most significant findings of this study was the marginal effect of natural light brightness levels on visual physiological stress in VR forests, with the pupillary unrest index decreasing significantly with the increase of natural light brightness; Secondly, the study analyzed the influence of natural light brightness levels in VR forests on the visual engagement behavior of eye tracking, that is, bright forest environments showed an overall trend associated with longer fixation duration, less saccade duration, and greater fixation direction ratio; Thirdly, in terms of visual perception evaluation, the study found an inverted U-shaped trend of mood, restorative perception, perceived safety, and natural light brightness level in VR forests. In addition, the study also found a significant correlation between visual physiological and psychological indicators in VR forest natural light visual perception experiments. These findings help us understand the visual perception effect of forest nature light exposure as a whole, and provided important clues and a basis for future research on improving the visual comfort of forest natural light.
模拟自然光亮度对虚拟现实森林视觉感知的影响:眼动跟踪研究
虽然自然光对人类的健康和福祉至关重要,但不同亮度的光线对森林视觉感知的潜在影响却尚未得到讨论。本研究利用受控眼动跟踪实验,探讨了在虚拟现实(VR)森林环境中,从最暗到最亮的七个模拟自然亮度等级对 118 名参与者视觉感知的影响。本研究最重要的发现之一是自然光亮度水平对 VR 森林中视觉生理压力的边际效应,随着自然光亮度的增加,瞳孔不稳定性指数显著下降;其次,该研究分析了VR森林中自然光亮度水平对眼动追踪的视觉参与行为的影响,即明亮的森林环境表现出与更长的固定持续时间、更少的囊回持续时间和更大的固定方向比相关的整体趋势;第三,在视觉感知评价方面,该研究发现VR森林中的情绪、恢复感知、感知安全和自然光亮度水平呈倒U型趋势。此外,研究还发现,在 VR 森林自然光视知觉实验中,视觉生理和心理指标之间存在显著的相关性。这些发现有助于我们从整体上了解森林自然光照射的视觉感知效果,为今后提高森林自然光视觉舒适度的研究提供了重要线索和依据。

期刊介绍: The Journal of Environmental Psychology is the premier journal in the field, serving individuals in a wide range of disciplines who have an interest in the scientific study of the transactions and interrelationships between people and their surroundings (including built, social, natural and virtual environments, the use and abuse of nature and natural resources, and sustainability-related behavior). The journal publishes internationally contributed empirical studies and reviews of research on these topics that advance new insights. As an important forum for the field, the journal publishes some of the most influential papers in the discipline that reflect the scientific development of environmental psychology. Contributions on theoretical, methodological, and practical aspects of all human-environment interactions are welcome, along with innovative or interdisciplinary approaches that have a psychological emphasis. Research areas include: •Psychological and behavioral aspects of people and nature •Cognitive mapping, spatial cognition and wayfinding •Ecological consequences of human actions •Theories of place, place attachment, and place identity •Environmental risks and hazards: perception, behavior, and management •Perception and evaluation of buildings and natural landscapes •Effects of physical and natural settings on human cognition and health •Theories of proenvironmental behavior, norms, attitudes, and personality •Psychology of sustainability and climate change •Psychological aspects of resource management and crises •Social use of space: crowding, privacy, territoriality, personal space •Design of, and experiences related to, the physical aspects of workplaces, schools, residences, public buildings and public space
