Evaluation of natural light in a house～Research on a glare condition that obstructs face-to-face communication in a room～
It is very important to investigate the influence that natural lighting gives to communication in a house. This is because a lot of communications are performed frequently in a house. We have investigated natural lighting environment in the real house which had been hardly performed. The scene with possibility to become a problem was found out by the investigations. Therefore, we examined various conditions of lighting environment by use of 1/10 size model of room and doll. As a result, we found that the dolls expression had trouble seeing by so-called silhouette phenomenon. We investigated whether this find occurred at a real house. By having investigation, a silhouette phenomenon occurred same as examination of a model. We used the Luminance -Brightness Converting System from luminance distribution pictures to examine the parameters of a silhouette phenomenon. In consequence, there is close relation between easiness in seeing facial expression and brightness value on a face
