Outline of Final Research Achievements

In this study, we applied wearable sensors to monitor body movements and center-of-gravity shifts during nursing actions, and aimed to construct a training support system that enables intuitive understanding of the state of one's own body movements displayed in VR. We established and demonstrated elemental technologies to distinguish nursing actions by applying wearable technology, center of gravity shift using smart insoles, and ankle joint motion using sensory garments. Furthermore, we constructed a VR environment for the purpose of nursing training.

Academic Significance and Societal Importance of the Research Achievements

看護業務では被介護者の介助において被介護者の身体を直接支えるため、その際の動作姿勢が腰痛症を引き起こす要因となり得る。熟練者の身体動作との差異の把握が可能になれば、自己学習により効果的な看護技術習得を促進し腰痛症の予防に有用と考えられる。本研究では，看護動作における重心移動，身体関節動作，着用者への提示といった要素技術を実現した．また，看護動作習得のための学習支援システム実現への道筋を示した．
