摘要

本文探討我們所提出的動作學習虛擬實境系統，利用動態時間校準方法進行學員評估。該系統可以透過KINECT裝置擷取骨架資訊比較使用者與教練的骨架資訊，教練的骨架資訊來自一個事先做好的動畫，學習績效則是基於教練與學員兩者的骨架資訊的相似度，而骨架相似度是以尤拉距離計算。為了瞭解這動態時間校準方法的準確性，我們針對這些實驗樣本去比較動態時間校準方法所計算的值與六位研究人員的評分。

This research explores an assessment of motion learning employed a dynamic time warping (DTW) method for our proposed virtual reality system. This system can capture the skeleton information from a user by the Kinect device to compare to the trainer’s skeleton information. The trainer’s skeleton information is an well-done animation in advance. The learning performance is based on the similarity between the skeleton information of trainer and student. The similarity is computed by the Euclidean distance. To understand the correction of this method, we compare the value of DTW method with the score from six researchers assessing for each experimental sample.
