Description Method for Unattended Ambient information and its phychological impacts

我们对环境的感知和欣赏可能不仅取决于一些主导因素，而且还取决于它们的背景。然而，环境感知中的环境视觉信息很少被考虑作为环境变量。本研究试图开发一种个人计算机程序来提供在所提议的环境中的给定点的环境视觉信息的视觉表示和统计分析。一些实证研究检验了该项目获得的这些措施与一个地方的人类感受的相关性。在第一年，该项目通过应用于9个模拟的居住社区景观进行了检验。阐明了该程序得到的一些度量与人的反应之间的数值关系，如“天然人工”的判断与绿地可见面积的关系、“受压-开放”的判断与可见空间体积的关系。从结果中提取了两个数值度量：一个是当感知者环视一个视点时场景的视觉复杂度，另一个是当感知者在环境中移动时的顺序变化。结果总体上支持该程序所获得的用于解释视觉复杂性的测量的有效性，尽管后者的相关系数较低，这被认为是模拟方法的结果，即幻灯片不足以引起顺序知觉。因此，在今后的研究中还应尝试其他的模拟方法。

Our perception and appreciation of the environment may depend not only on some dominant elements but also on the background of them. However ambient visual information in environmental perception has rarely been taken into account as a environmental variable. This study attempted to develop a personal computer program to provide a visual representation and statistical analysis of the ambient visual information at a given point in a proposed environment. Some empirical studies examined relevance of these measures obtained by the program to the human feelings of a place.In the first year, the program was examined by applying to nine simulated landscapes of housing neighborhood. The numerical relations between some measures obtained by the program and human responses, such as the relation between the judgment of "naturalartificial" and the visible area of greenery, and the judgment of "oppressed - open" and the visible spatial volume, were clarified.In the second year, the program was applied to measure the degree of perceptual complexity in visual scenes. Two numerical measures were extracted from the result : one is visual complexity of a scene when the perceiver looks around a view point, and the other is a sequential variation when the perceiver moves through the environment. The result generally supports the validity of the measures obtained by the program for explaining visual complexity, although the correlation coefficient of the latter was, lower, which is believed to result from the simulation method, i. e., the slides were inadequate to elicit sequential perception. Thus other simulation methods should be tried in the future study.
