第六章 結論與未來發展
6.1 結論
在本論文中，我們以 3D 動畫引擎為基礎發展平台，結合瑜珈運動知識，實作出瑜 珈運動教學系統。結合程序式動畫技術 IK、FK 和 Lookup table，設計出各種動作子程 序，利用子程序之間彈性的組合，完成各種需要的瑜珈動作教學。透過模組化的設計概 念，使我們的系統有更好的擴充性。為了讓不同的使用者都可以量身訂做合適的運動學 習，我們增加了客製化人物的功能，並且可透過腳本來調整運動相關的參數和不同的動 作學習腳本，也加入了晃動和搖晃等具有瑜珈特色的運動效果。
在實驗評估中，我們將關節柔軟度、運動平衡感和穩定度參數，以單一維度來做變 化調整，從實驗結果中可明顯看出運動參數調整對人物運動的影響。另外，我們也實做 了三種人物角色，並以同樣的動作來做實驗比較，從不同角色中看到實際的瑜珈動作變 化，以證明本系統可對於不同的人物進行客製化。最後，我們進行了使用者評估實驗，
在實驗中分為三個階段，分別為系統操作體驗、客製化人物情境實驗和教學錄影帶比較 實驗，實驗的結果顯示各方面皆高於中間值，使用者對本教學系統在介面、功能和瑜珈 運動學習上的接受度是較佳的。
6.2 未來發展
透過使用者的評估實驗中，我們得到一些回饋意見，可以用來改進本系統。在系統 的操作介面的部分，可使用圖示按鈕讓操作更直覺，增加放大縮小比例尺功能和更多的 速度選擇，顯示器背景和運動場景也可在更美觀。在人物角色方面，模型和動作的擬真 度可再加強，也可再加入更多人物細節的參數。在系統功能方面，可以增加有助於學習

的運動參數，例如呼吸和節奏等，有助於提升人物的擬真度和運動的逼真感。在瑜珈動 作的實作部分，目前是以程序式動畫為產生方法，未來也可以搭配動作擷取資料，以取 得真實人物的動作資料作為分析，來加強程序式動畫的動作擬真性和增加更多的動作變 化。目前動作庫中的動作只有五種，未來可利用程序式動畫擴展性佳的特性，增加需要 的程序來實作出更多的瑜珈動作，使本系統在動作學習上更加的豐富。在教學方面，可 加入客製化的教學教材，以循序漸進的方式讓使用者學習，還可以將多種動作加以組合 出有變化的動作，並搭配學習時間，使學習的內容更加多元，並且加強學習的成效。
本研究針對瑜珈運動來實作，透過我們的研究方法，也可以擴展到不同的運動學習，
像是跳舞或游泳等，以簡單的肢體程序模組為基礎，可組合出更多種複雜的動作和運動。
未來也可以結合硬體設備，配合偵測人物動作的感測器，以壓力或燈光等方式，於使用 者運動時給予適當回饋，對於運動學習會更佳有幫助。
