The purpose of this study is to clarify the influence that a Planar shape affects the spatial impression, throughout experimental verification about the spatial recognition characteristic of spatial volume perception of the non-rectangle space where one side wall is diagonal
The results from the experiment comparing the feeling of spatial volume in non-rectangular space and the rectangular space are fallowing;
1) The evaluation of the spatial volume changed by the angle of a diagonal wall.
2) When the angle of a diagonal wall is 20°-35°, subjects had tendency to evaluate the spatial volume of rectangle space was bigger than non-rectangle space.
3) The direction of a diagonal wall and the dominating eyes of subjects were related to the spatial volume perception.
