Abstract
In this paper, we examine the sense of "visually-closed spaces". We discuss the perceived volume, the sense of oppression and the degree of the sense of oppression, using a 1/10 scale model and life-sized model. This paper is mainly consisted of two experiments, which are based on the consideration that the sense of oppression and openness should be dominated by the perceived volume of spaces. In Experiment I, we deal with the perceived volume of "visually-closed spaces" with the 1/10 scale model and make it correspond to physical values. In Experiment II, we discuss the perceived volume of "visually-closed spaces" with the life-sized model of which the walls and ceiling were movable (min. : 1800×1800×CH. 1800mm〜max : 5400×5400×CH. 4800mm). The perceived volume is measured with the magnitude estimation method, and we make the data correspond to physical values. We get results that the perceived volume may be dominated mainly by the physical volume andthe configuration of the plan, for example the solid angle of the walls of spaces.
