在這項研究中，為了使通過太極拳進行注意力訓練更加有效和容易，我們提出了一種新穎的基於太極拳的注意力訓練遊戲，該遊戲指導受試者使用虛擬現實（VR）和運動分析來練習太極拳。通過演示一系列太極拳動作的虛擬教練，受試者可以隨時跟踪教練的動作。同時，動作捕捉設備會收集對象的身體關節3D位置，並使用深度學習模型進行進一步分析，以評估太極拳動作的順序正確性和準確性。我們利用遷移學習技術解決了太極拳數據量較小的問題。在對20名正常人進行的初步測試中，太極拳動作的識別準確率達到了超過96％，並且在一定程度上，平衡分析反映了人體重心的位置變化。我們還比較了經過和未經過遷移學習的模型的性能，以證明轉移學習的重要性。這些探索的結果表明，該原型系統可作為注意力訓練系統的可行性，並且有可能成為輔助治療方案。;In this study, to make the attention training through Tai Chi more effective and easier, we proposed a novel Tai Chi-based attention training game that instructs the subject to practice Tai Chi using Virtual Reality (VR) and motion analysis. Through a virtual instructor demonstrating a series of Tai Chi action, subject is asked to follow the instructor’s movement at any time. Meanwhile, subject’s body joints 3D position is collected by motion capture device for further analyze using a deep learning model to evaluate the order correctness and precision of the Tai Chi actions. Transfer learning technique is utilized to solve the problem of small size of Tai Chi data. Preliminary tests with 20 normal individuals, the recognition accuracy of Tai Chi actions reached to nearly 97%, and to a certain extent, the balance analysis reflected the position change of the body’s center of mass. We also compared the performance of the model with and without pre-trained to demonstrate the importance of transfer learning. The result of these explorations shows the feasibility of this prototype system as an attention training system and it’s potential of being an auxiliary treatment option.
