| Abstract |
The purpose of this study was to examine whether or not the sense of continuity between two spaces was dependent on the equivalence of brightness perception of two spaces (experiment 1), and to assess the relationship between how realistically the observers recognize the sense of continuity and the distribution of light within the spaces (experiment 2). It was found that the equivalence of brightness perception of two spaces had no significant effect on the setting of the optimum illuminance to recognize the continuity. However, the estimation value, which indicate the recognizing level on the sense of continuity, was different with the types of lighting distribution within the spaces, and the continuity was the most realistically recognized by the observers when the two spaces were uniformly illuminated. In conclusion, it appears that we would have the more real sense of continuity between two spaces when the presence of lighting sources in the observed space over the window was visually inconspicuous as compared to that of observer's space. |
