本研究主要建立一套以四台運動追蹤器環繞在受測者四周之人體運動追蹤系統，研究內容包括人體運動追蹤器(V2000)之建構、四台運動追蹤器之座標註冊原理與自動化註冊流程、四台V2000資料整流、利用不同模組之CCD資訊進行定位、運動追蹤器工作區間之量測和改進與資料之時序插補處理。
本文也提出一套由定位標誌點，獲得手臂骨架關節參數之方法，其中也進行腕部關節位置搜尋之實驗，可更精確的得到人體與關節軸位置之間之關係。並針對人體各關節軸之運動範圍，利用AnnA人體掃描器，進行關節活動範圍之量測實驗。若使用本文所提出之關節角度計算方法，可將人體手臂運動利用此運動追蹤系統擷取並記錄下。

The purpose of this study focuses on the implementation of a human motion tracking system. The contents of this study are the construction of four motion tracking modules, automatic registration of the four modules system, data rectification of the system, using labeling group to compute the 3D position of the markers, measuring and improving the capturing range, and using the time sliding method to slice the capturing data for the same time sequences.
We also proposed a method to construct the parameters of the human skeleton from the captured marker positions. In order to get an accurate relationship between the markers and the body, experiments were constructed to find the position of the wrist joint axes and to measure the motion ranges of the joint axes, and to compute the joint angles. This information is needed for recording the joint angles after tracking the arm motion.
