This is fundamental study on the nature of environmental perception in the natural situation, which is performed without particular effort in our daily lives. We tend to associate visual perception with an act of paying attention to an object and looking at it. It is the common structure of subjective eye and objective target. This dualistic structure, however, doesn't necessarily apply to environmental perception. Human is always surrounded by the environment and always see it, in other words, keeps on receiving the visual information from it unconsciously and automatically. We call such information "ambient visual information". Though importance of it in environmental perception has been pointed out, few experimental studies have focused on it. The purpose of this study is to investigate how perception of ambient visual information changes in the natural situation of moving through an exterior space.Since it is difficult to have subjects report about unconscious process directly, the … More following indirect approach was employed. The subjects continuously rated the sense of oppression against surroundings while moving along the given route. On the other hand, ambient visual information from surroundings along the route was described as various variables (such as solid angle of surrounding buildings). Our precedent research has showed that the both variables correlate, that is, sense of oppression reflects perception of ambient visual information. In this study, the relationship between the both variables was analyzed in detail, and how perception of ambient visual information changes with sequential changes of spatial composition was researched. It was found through two experiments in actual space and virtual space that its perception concentrated to each specific direction and extent in three kinds of situation of "Approach to a building forward", "Space opens symmetrically" and "Space opens asymmetrically". This result shows that human in locomotion shifts the direction and extent where ambient visual information is perceived dynamically. The fact that the shifts are caused by changes of spatial composition suggests that this unconscious process of environmental perception functions for moving smoothly and alerting to hidden danger.What this study revealed is only one nature of perception of ambient visual information. Nonetheless, it is notable that a new experimental paradigm has been proposed for future study on environmental perception in natural situation. Less

这是对自然情况下的环境感知性质的基础研究，在我们的日常生活中没有特别的努力。我们倾向于将视觉感知与关注物体并观看它的行为联系起来。这是主观眼睛和客观目标的共同结构。然而，这种二元结构并不一定适用于环境感知。人总是被环境包围着，总是看到环境，也就是说，不断地无意识地、自动地接受环境的视觉信息。我们称这种信息为“环境视觉信息”。环境知觉中的无意识过程是一个重要的过程，但对其进行的实验研究却很少。本研究的目的是探讨在自然环境中，被试在穿越外部空间时对环境视觉信息的知觉是如何变化的。由于被试难以直接报告无意识过程，因此，在实验中，被试对环境视觉信息的知觉是通过无意识过程来进行的。实验结果表明，在无意识过程中，被试对环境视觉信息的知觉是通过无意识过程来进行的，而在无意识过程中，被试对环境视觉信息的知觉是通过无意识过程来进行的。在无意识过程中，被试对环境视觉信息的知觉是通过无意识过程来进行的，而在无意识过程中，被试对环境视觉信息的知觉是通过无意识过程来进行的 ...更多信息 采用了以下间接方法。受试者在沿着给定的路线移动时，不断地对周围环境的压迫感进行评分。另一方面，来自沿着环境的环境视觉信息被描述为各种变量（如周围建筑物的立体角）。我们的前期研究表明，这两个变量是相关的，即压迫感反映了对周围视觉信息的感知。本研究详细分析了这两个变量之间的关系，并研究了空间构成序列变化对环境视觉信息感知的影响。通过在实际空间和虚拟空间中的两个实验发现，在“向前接近建筑物”、“空间对称打开”和“空间不对称打开”三种情况下，其感知集中于每个特定的方向和范围。这一结果表明，运动中的人动态地改变了感知环境视觉信息的方向和程度。这种变化是由空间结构的变化引起的，这表明这种无意识的环境感知过程具有平稳移动和警惕潜在危险的功能，本研究揭示的只是环境视觉信息感知的一种性质。尽管如此，值得注意的是，一个新的实验范式已经提出了未来的研究在自然情况下的环境感知。少
