Setting eyes of people isn't always necessarily on visual cues, in actual buildings. It is necessary to examine the influence of visual cues on motion perception etc., in consideration of temporal length of setting eyes on visual cues. For this purpose, parameters that are directly necessary to estimate a probability of visual motion perception, like length of setting eyes on visual cues, distance between subjects and visual cues etc., are measured in existing buildings. And statistical analysis of the data is done. It was found that length of setting eyes on visual cues is about 7.0s in average, regardless of subjects' age, sex and buildings. Distance between subjects and visual cues is about 2.4m in average.
