Conference Paper
脳卒中に伴う身体機能障害を有する患者に対し行われるリハビリテーションにおいて,医療機関への移動による身体的負荷や感染リスクを軽減するために,任意の場所でリハビリテーションを行えるシステムが望まれる.そのため動作を定量的に表す指標や患者に説明する評価理由の分析が必要である.そこで本研究では,人物の姿勢推定技術により各関節位置や可動角度の時系列情報を抽出し,定量的評価指標や評価理由の推定を試みる.具体的には,姿勢推定情報から体幹の傾斜や双肩の傾斜の二つの代償動作の度合いや肩や肘の関節の角度を算出する.また,Multi-Head Attention 層を含むニューラルネットワークを用いた評価モデルを構築し,時系列上での重要度を算出することで評価理由の推定を試みる.検証実験では,作業療法士が脳卒中後...

With projection mapping, we can control the appearance of real-world objects by adding illumination. A projector can be used to control light reflected from an object, where the reflected light depends not only on the projection but also on the reflectance and environmental light. Because the resulting colors are affected by the reflectance and env...
