摘要：The final goal of this research is grasping the relation between visual quality and shape of a real space. The visual quality of a real space means effects on human psychology or difficulty of evacuation. As the first step, this paper argues a description method of spatial complexity in terms of visibility. A simple concave figure can be used as an examine space to calculate distribution of visible quantity. Firstly, we define formulas to obtain exact value of visible quantity in the space. Then, visible quantity distribution of the space is visualized based on the formulas. Finally, we try to describe the complexity of the space. Average and standard deviation of the visible quantity distribution are used to describe the complexity and transition of them is observed with transforming the space. The relationship between the intuitive impression of space and visible quantity was suggested as a result of examinatio n. We present the possibility of evaluating visual quality of a real space by visible quantity of the space
