| Research Abstract |
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.
