摘要: | 近年來,隨著多媒體設備的發展,特別是頭戴式顯示器的出現,運動的學習已經不再局限於進行課堂學習,由教練進行指導,而是可以透過觀看多媒體教學影片進行學習。然而進行多媒體學習雖然很方便,但卻不能及時獲得像真實教練引導的回饋和互動性,同時也無法掌握自己練習的準確性和完整度。
基於以上問題,本研究提出了一套基於慣性測量裝置進行動作辨識和評估的系統,在本研究中主要以觀看頭戴式顯示器的動作引導,進行十六式太極拳動作練習為例。本研究利用搭載三軸慣性測量的智慧型手錶對太極拳動作進行辨識和評估,可以讓太極拳学生更加準確的了解自己練習的完整度。進而可以讓太極拳学生在沒有教練的情況下,使用本系統獨立完成太極拳動作的練習,並獲得相應練習的完整度回饋。 相較於以往研究根據用戶練習數據進行機器學習,獲得太極拳動作的模型不同,本研究採用深度攝影機技術來獲得太極拳教練手腕的示範動作,使得每個招式的模型更加精準。之後我們根據学生的練習數據進行辨識,獲得了極高的正確率。最後,我們應用機器學習的方式,根據学生數據和教練動作的差距,計算学生練習的完整度,給予学生完成情況的評估,以利太極拳練習。 In recent years, with the development of multimedia equipment, especially the appearance of head-mounted display, sports learning is no longer limited to classroom learning, with a coach to guide your movement, but can through watching multimedia teaching videos to learn. However, although the multimedia learning is very convenient, but student cannot get the feedback from the coach, also student cannot get the accuracy and completeness of their practice. Based on the above problems, our research presents a system based on inertial measurement unit for movement recognition and evaluation. In our research, we mainly let student watching a Tai-Chi Chuan learning video with sixteen movements through the head-mounted display. Then we use a smart watch with three-axis inertia measurement unit for Tai-Chi Chuan movement recognition and evaluation. Student can get more accurate understanding of their own exercise integrity during Tai-Chi Chuan practice. And then student can use the system to complete the practice of Tai-Chi Chuan without a coach on their side, and they can get the evaluation from the completeness feedback. Different with the previous study, Tai-Chi Chuan movement model is using practitioner practice data for machine learning. Our research uses depth camera to get the Tai-Chi coach’s movement, making each movement model more accurate. We got a very high accuracy precision using different students practice data for recognition. Finally, we use the machine learning to calculate the completion of the student practice according to the difference between student movement and coach movement. Then we give student score as evaluation in order to help them finish the Tai-Chi Chuan practice. |
