The purpose of this research is to clarify the spatial cognition of the visually impaired in model courses. Experimental courses were a straight course without any obstructions, and 6 kinds of bent course. Subjects were 5 totally blind pedestrians, 5 eye-masked pedestrians, and 5 normal sighted pedestrians. The results are as follows. (1) In the case of the blind subjects, the wider the angle of the corner is, the lower the rate of the independent walk is. (2) The behavior of losing the way of the eye-masked is 2 times as much as that of the blind. The incidence of losing the way at the corner is 85 %. (3) In the correct answer for sketch map, the score of the blind is 90 points, while that of the eye-masked is 50 points. Even if the angle of the corner changes, the blind can draw the sketch map correctly. (4) At the destination, the difference of the direction angle of the blind is 19° and that of the eye-masked is 51°.
