経路歩行における迷いと空間把握:　模擬経路における視覚障害者の歩行と立ち止まり　その2

摘要

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°.%晴眼者は視覚からの情報により、現在の居場所がどのような空間 であるかを素早く把握することが可能である。それに対して視覚障 害者は視覚による情報は得にくく、聴覚、臭覚、触覚、暑さ寒さ、 風の方向、人の動きなどから情報を得て、その場の空間を把握しな ければならない。
