Abstract
The purpose of this study is to measure people's visual perception of the space size particularly concerning to its relation to the surface constituting them. The present report is concerned with the results of the experiment using simple scale-models. This experiment aims at analyzing both the effects of anisotropy of space that is caused by the viusal composition of space on the perception of volume, and that of space continuity which is varied according to variety of partitions. The summary of the results are shown below. (1) Effects of anisotropy of space are independent of scales of scale-models. (2) Among the surfaces constituting visual space, the front affects the most upon the perception of visual volume, the side and the top follow this. (3) The distinction on the floor made by the different texture is less effective on the perceptional division of visual volume than the distinction made by other surfaces constituting space. (4) The degree of the perceptional division of visual space made by partition is roughly in proportional to the size of the partition. (5) The factor of distinctness in visual space is related to both the degree of the division of visual space made by the sureface constituting visual space and the distinction made by the difference of texture on the floor. (6) To make one room look like two rooms with a partition, the partition should not be so small.
