Outline of Final Research Achievements

The purpose of this study is to experimentally verify the hypothesis that a slow system for constructing spatiotopic coordinate representation enhances spatial recognition accuracy within the environment and enables smooth interaction between the body and the environment. Psychological experiments were conducted in a virtual reality space, where participants performed free body movements (eye and body movements) during the experiments. Upon conducting visual search tasks, size judgment tasks, and size constancy tasks, two main findings were revealed: (1) spatial recognition accuracy improves through body movement, and (2) the mode of spatial recognitions are qualitatively different for the body moving conditions compared to the static conditions. These findings provide useful insights for understanding the mechanism of constructing spatiotopic representation based on body movements, which is the basis of visual stability.

Academic Significance and Societal Importance of the Research Achievements

本研究では仮想現実空間において3つの実験(視覚探索、大きさ/長さ判断)を行い、2次元平面上における類似課題とは異なる心理学的特性を見いだすと共に、身体運動の重要性を明らかにした。そのために本研究結果は、いまだ心理学的、神経生理学的な研究の進展が遅れている環境座標表現構築の機序解明に向けた有用な手がかりになるという学術的意義がある。またその社会的意義は、空間デザインに対する指針を明示したことにある。つまり、環境、居住空間、あるいは交通網等における空間デザインでは、利用者自身の身体運動に基づいて、その脳内に適切な環境座標表現が構築できるようにサポートすることが望ましいデザイン指針となる。
