近年來，科技產業發達，使得許多人的生活開始依賴科技產品，進而影響人們平時的休閒興趣。許多人開始變得足不出戶，與他人的交流方式改為網路與遊戲。然而科技開始強調真實性與準確性，即使在室內空間，也想擁有身歷其境的體驗，隨著科技的突破，出現了虛擬實境的技術，此技術的出現滿足了使用者的需求，在此類技術中，使用者對於準確性的標準開始提高。
本篇論文主要是為了使用者能在簡單設備的環境下，準確性的計算出使用者的三維空間位置。利用兩個已知基地台，透過無線訊號使用雙球公式，算出兩球相交的平面公式，由於兩球圓心的向量必定垂直於相交平面，計算出平面中心點。利用點到平面之距離公式，以此得知平面分別與兩球圓心的距離，利用餘弦定理算出使用者與兩球圓心之距離與角度，刪除不符合參數的座標，得出使用者X,Y,Z座標，達到讓系統知道使用者位置的目的。
本研究結合各種應用，可以準確性的使其捕捉到使用者位置，以此做出對應，例如：使虛擬實境系統做出更針對某些特定玩家的舉動，讓使用者彷彿身臨其境，更加逼真；使室內空間能夠依照使用者目前位置給予適當資訊，也方便管理者查看使用者群體之位置。

With the development of science and technology, many people have seldom left theirs house, the impact of that on people is their lifestyle has been changed. They communicate with each other by Internet. So the technology products start to focus its authenticity and accuracy. Even though the people at interior space, the products have to make them experience the incident personally. Along with the breakthrough of technology, the Augmented Reality(AR) is developed.
This dissertation provides the simple equipment for predicting the three-dimensional position of the system user. Based on the on demand given Base-Stations, the distance between the user and the BSs can be evaluated according to the wireless signal from the system user. Therefore, the functions of the two sphere based on the two BSs can be established. Furthermore, the intersection of these two sphere can be found including the plane and the function of the intersection circle. According to the vector from one BS to another, the intersection between this vector and the found plane will be the only one point which indicates the center of the intersection circle. By on demand given limitation or conditions, only the points which can satisfy the conditions can be chosen as the predicted location of the user.
The study can get the position of the user accurately, it can make many application to reply someone of users to do the special action. Make user experience the incident personally and feel more lifelike. It can also make the system give some appropriate information with the site of user at indoor place, and help the supervisor examine where the users stand.
