B-09 三次元空間における図地分化

抄録

The figure-ground articulation in three-dimensional space, which is a concept adopted in the space design, was psychologically examined. We defined the figural space as the inside and the ground space as its surrounding. The subject peeped into the box through a window and judged the insideness/outsideness of the space and the belonging of the wall in front. As results, the subjects felt the outsideness when they saw the wall considerably projecting out to them. A further examination revealed that the continuity, in color as well as in shape, of walls in the room was also important. Some differences between the classical articulation and this phenomenon were shown.
