街路空間における道路平面形状の認識に関する研究: 曲がり角に着目した実空間・CGパース実験

摘要

本研究では、経路探索中の透視図・平面図的認知の変換に着目し、rn以下の傾向を見出した。rn①視点と同じ位置に中心、を持つ曲がり角の透視図・平面図的認知のrn変換と、視点から離れた位置に中心を持つ曲がり角に関する透視rn図・平面図的認知の変換では、後者の変換のほうが後者の変換のほrnうが個人のスケッチマップ作成の正確さとの関係が深い傾向にあrnる。%We performed experiments using real space and Computer Graphic perspectives to investigate the characteristics and tendencies of the recognition of road shapes from the perspective view to the ground plan.rnIn the real space experiment, a subject is asked to draw a sequence of road shape planes from the range that he can see from specified corners along a predetermined path. Afterwards, the subject is asked to recreate a complete map of the entire path from memory. Finally, the subject is asked to repeat the experiment but this time without having to recreate the small sketches, only the complete map.The computer graphic experiment asks subjects to choose from a series of options the road shape plane that is equal to a computer graphic perspective displayed on a screen.rnThe result of the experiment shows that if the subject is distant from the center of the road convergence point, his perception of the road shape is altered. Furthermore the results show that there is a tendency for the user to perceive road shapes to be at angles that are closer to 90 degrees from the direction of forward motion.
