PERCEPTUAL DETERMINANT OF THE SENSE OF CONTINUITY BETWEEN TWO SPACES: TEST OF LIGHTING COMMONALITY HYPOTHESIS

摘要

We examined the perceptual determinant of the continuity perception produced by lighting between separated spaces. The experiment for examining the effect of the shape of a room on the illuminance setting for continuity was conducted on the hypothesis that the sense of continuity is generated when observers perceive two spaces to be under common lighting condition such as skylight. If the hypothesis is correct, the optimum illuminance for the observers to sense the continuity is to vary with the room shape. The results showed that the room shape conditions had no significant effect on the optimum illuminance. However, the relations with optimum illuminance inside and illuminance outside were found.
