summary In this study, it was hypothesized that people’s performance of way-finding depends on the characteristics of street-scapes, i.e., the more visual information exists the easier people find their own ways. This relationship was investigated by an experiment using an environmental simulator and analysis of the subject’s behavioral data recorded by the simulation system. Three scale models (1/150) of identical maze patterns (300m x 300m) which have different street-scapes were created and set in the simulator, in which an endoscope connected to CCD color TV camera controlled by a system operated by a personal computer. Three types of streets are: (1) having no characteristics with monotonous surface, (2) having characteristics on each corner with different buildings, (3) having characteristics along the streets with trees, columns or fences. The simulator allows a subject to move through the scale models and looking around, using a “joy-stick“ for viewing the scene as projected on 100-inch CCTV screen. The control system of the simulator records all signals generated by the “joy-stick“ every 0.01 second, and thus exact position within the model space and the viewing direction at given moment can be stored in the computer memory, which can be used to analyze the subject’s behavior. The task of a subject was to find the way which was previously shown by the screen. Three male and three female subjects for each of three street types, for a total of eighteen subjects participated in the experiment. An analysis of the trace of movements and viewing directions generally supported the hypothesis that the street with visual characteristics were easier to memorize the route although there was a large difference in performance among subjects. It was also noted that there were three different strategies of way-finding according to the subject: one group of subjects seemed to rely on well structured knowledge of the route, i.e., the cognitive map, and the other group seemed to rely on incoming visual information of the changing scenes, and the last group seemed to find the way using both the cognitive map and visual information depending on the situations.
