| Outline of Final Research Achievements |
It is necessary to design environments with high accessibility for indoor and outdoor environments that everyone can use safely and comfortable. The initial goal of this study was to evaluate environmental accessibility with various contexts. However, the research plan was changed to due to the difficulty of measurement experiment with a various subject. Thus, we updated a research plan to develop a technology that can evaluate and apply environmental accessibility under various conditions by simulating movements in a virtual space based on measured human data. For this purpose, we conducted a gait evaluation study using a sparse set of IMUs, developed a safe route recommendation system based on the tripping risk evaluation results, and developing a technology for evaluating the risk when using different lower limb orthoses.

インクルーシブ環境の実現のため，利用者の身体性を考慮しつつ，屋内外環境に対してアクセシビリティを定量評価できなければならない．そこで，実環境の3Dレーザ計測点群上で，想定利用者の歩行動作をシミュレーションし，アクセシビリティを定量評価することを試みた．
現在は健康的な若年者・高齢者・一部の下肢装具ユーザしか模擬できないが，提案技術によりアクセシビリティを定量評価でき，これに基づく歩行ルート提案，コンテクスト(選択ルートや下肢装具の種類)を考慮したリスク評価を行えることを確認した．このように，シミュレーションベースで様々な利用者に対する環境点検を実現できる点において，本研究は社会的意義を持つ．
