In this research, we paid attention to one of the man's high and non-particular sensations, the sense of time, in an effort to examine whether or not the sense of time could be used as an index in quantifying the interaction of man and his space. 20 courses were selected and subjects were respectively directed to walk the specific courses in order to evaluate their self-affection, image of the course treaded, and sense of time. The walking distance was identically set in experimenting the sense of time. As a result, subjects felt the walking time shorter in a comfortable setting and longer in an uncomfortable scene. To be more specific, their sense of time in courses through a shopping district with many distractions was neither long nor short, while their sense of time tended to become shorter where there were obstacles such as congestion of passers-by and bicycle traffic. As the walking distance was set shorter, their sense of time became shorter than the actual time and their walking pace became slower. It should be pointed out that this experiment involved some problems. The walking distance was in fact not identical in some courses selected, and the subjects became tired as a result of continuous walking to affect the evaluation. Therefore, we intend to solve those problems and further our study of the interaction of man with his space and sense of time.
