Abstract
This paper investigated the effect of the lighting factors on the atmospheric evaluation of the texture of the interior material. In a full-sized model living room with diffusional lighting from its ceiling, an experiment was conducted under three illuminance conditions (65lx, 200 lx and 650lx), each of two lighting-color conditions (Daywhite color and Incandescent color). The results showed that the evaluation was constituted by four factors, ‹Evaluation›, ‹Potency›, ‹Appearance›, and ‹Modern-ness›. ‹Evaluation› and ‹Modern-ness› were affected by illuminance, ‹Potency› was affected by lighting-color, and ‹Appearance› was affected by both lighting-color and illuminance. Also there was a tendency for rough and dense surface to be strongly affected by the lighting conditions. The reason for this was thought to be that the appearance of the surface was varied with illuminance, and so the evaluation was affected by this change of appearance. Also, it was considered that the evaluation of softness was affected by lighting-color in the same way as warmth.
