Outline of Final Research Achievements

The purpose of this study is to develop an XR system, named "Place Avatar", designed to transplant a place to another physically different space or virtual environments, reproducing the subjective meaning of the place and the social activity, and to demonstrate the operability of place sameness, where one place feels like the same place as the original.
Experiments using 2D CG and 3D virtual environment reproductions of university classrooms, and an online survey using 2D CG reproductions of two cities, Shibuya and Sapporo, were conducted. In addition, factors of place sameness were explored by examining examples of place reproduction in Japanese culture. The findings suggest that place sameness can be effectively manipulated by through the reproduction of objects that are subjectively relevant to the meaning and the activity of that place.

Academic Significance and Societal Importance of the Research Achievements

本研究は、実空間の場所と同一と思えるバーチャル場所再現の実現に向けた最初の知見を得た。本研究が発展することで、高齢者の転居による認知症の防止、震災で失われた場所の再現、リモートワークの職場と自宅の同一化等の喫緊の課題から、意識アップロードにより人が仮想環境で暮らすための仮想世界への場所移植、他惑星への移住時に慣れ親しんだ場所をVR化して持っていく等の将来課題まで、様々なバーチャル場所再現の応用の基盤となる。
