摘要: | 鏡子在體育鍛鍊訓練中是一個非常重要的工具,它可以提供學員觀察自身影像並修正自身動作。傳統武術太極拳,時常會進行定式的練習,學員維持一個靜止的姿勢,但學員並不清楚自身的定式是否正確,此時就可以透過鏡子來協助。無論是跟隨教練在課堂上學習或是獨自練習時,只要使用固定不動的鏡子,當學員轉向就會超出視線範圍,或是在某些招式發生肢體遮擋的問題。本研究基於機器人攝影機與光學透視頭戴式顯示器,建立一個軟體鏡輔助太極拳練習之混合實境系統,將攝影機拍攝的影像顯示在軟體鏡上,利用機器人的移動性可以從多方位拍攝解決肢體遮擋問題,並使用頭戴式顯示器顯示軟體鏡,使軟體鏡一直保持在視野當中。配合太極拳學習系統,學員可以透過軟體鏡觀察自身的定式,並與虛擬教練的標準定式做比較,在混合實境中檢視及修正自身肢體動作。在本研究的結果顯示,軟體鏡在頭戴式顯示器的顯示視窗高度佔80%為最適合的呈現大小,學員可以觀察到自身動作的細節,也不會造成不適。另一方面,學員對於鏡像與正常影像的辨別,可以透過練習達成。在顯示視野中,一次只呈現一個與軟體鏡中學員影像同向的虛擬教練能夠達到較好練習成果,並利用機器人攝影機的移動性,對每個定式預設兩個拍攝方位,觀察定式中不同的重點,可有效提升定式練習的正確性。 Mirrors are a very important tool in physical exercise training, which provides students observe self-images and correct their movements. Tai-Chi Chuan (TCC), a traditional physical exercise, often practice static postures exercises. When students maintain a static posture, they are not sure whether their own postures are correct, then you can help through the mirror. But when you use a fixed mirror, you will have direction problems or occlusion problems in some postures following a coach or learning alone. This research based on robot cameras and optical see-through head-mounted display(OST-HMD) to develop a mixed reality system for learning TCC with software mirrors. The movable robot is used to capture image multi-directionally which is displayed on the software mirror to solve the occlusion problems. The HMD is used to display the software mirrors so that the software mirrors can keep in students’ view to solve direction problem. Students can observe their images through the mirror and compare them with the coaches in the TCC learning system to check and correct their own postures in a mixed reality. The result of this research shows the most appropriate size of software mirrors is in 80% height of FOV of HMD. Students can observe the details of their own postures without any kind of sickness in this size. On the other hand, students can identify mirrored images and normal images through practice. The better way to present the software mirror is one student’s mirror and one virtual coach who is in the same direction as the student self-image in the FOV of HMD. Robot cameras capture images from two preset directions for each static postures.Students can observe different key points with images captured from different directions to improve the correctness of static posture exercise. |
