Abstract
District residents know well about the problems faced by their own district. However, it is not easy to bring on a concrete discussion concerning space configuration. The space image drawn in each person's mind is different, and therefore, it is difficult to arrive at a consensus building. In this study, it was clarified by an experiment that one's memory can be incorrect, even for someplace quite familiar. Moreover, it was also clarified that the understanding of the space configuration could be deepened by presenting visual information.
