Abstract
The purpose of this study is to measure people's visual perception concerning the size of space, and chiefly to investigate its relation with the surface constituting them. In this investigation two points- "the visual definition" and "the apparent volume" -are mentioned, for the perception concerning the visual volume. "The visual definision" means the feeling that a visual space is limited by space-enveloping elements such as wall, fence, roof, etc. It is an eleven-point scale where degree "zero" is the condition bearing no definite element, like the outer space ; and degree "ten" is the condition with a complete definition like one being immobilized in a concrete block, unable to see anything. "Apparent volume" means the perceived size of space volume and it is a ratio scale, being measured by the perceived in comparison to a standard size of space that is valued a hundred. This paper tries to study the influences of these perception of volume and the relationship between each of them and physical elements by using scale-model spaces. By this experiment, it was made clear that the results of evaluation by simple scale-models were not different from the ones in a real space, and that the perception of volume, in a visual space, had a high correlation with the surfaces constituting those spaces.
