The Basic Experiment on Relation Between a Perception of Volume, Spatial Impression and the Space Occupied in the Room

The purpose of this study is to clarify the effect that shape and position of the space occupied have on perception of room volume and spatial impressions. The various shape and position of the space occupied is presented ran- domly. In experiment 1, The Method of Magnitude Estimation is used; subjects are then compared the volumes of two rooms. In experiment 2, subjects are then asked spatial impressions on 3 topics (i.e. sence of oppressed, feeling of cramped, feeling of comfortable). The results are summarized as below ; 1).Perceived room volume is smaller than an actual room volume. 2).Perception of room volume and spatial impressions has highly correlated with the wall area that covered by the object in the occupied space.
