摘要

本研究結合虛擬實境技術開發出一套非接觸式電子經緯儀電腦模擬教學系統，以模擬真實電子經緯儀從水平校正到工件量測等功能，讓學員能夠在一個無安全顧慮與貴重設備損壞之虞的3D虛擬環境中進行互動式的學習，亦可透過此系統來提高學員的學習成效與了解學員目前的學習狀況。

在本研究中主要包含系統開發與系統評估兩部分。首先在系統開發方面，本教學系統採用3D Studio Max（3DS）建構出虛擬電子經緯儀場景，再透過Visual Basic來建構虛擬軟體操作介面與各項規劃之功能項目，並與EON軟體進行整合連結，以提供使用者即時互動的場景畫面，再藉由電腦鍵盤指令的輸入與滑鼠的操作，以進行虛擬非接觸式電子經緯儀的互動式教學訓練。

在系統評估方面，由學習性實驗可得知受測者隨著操作次數的增加，其錯誤次數和操作時間隨之減少，最後趨於平緩穩定。再透過信度實驗分析可證明本教學系統為一個具有信度的系統，對於受測者在本教學系統之操作上具有相當程度之穩定性。此外，藉由虛擬實境教學與傳統教學之學習成效比較得知利用3D/VR模型來進行電子經緯儀之教學訓練，可給予受測者較清晰明確的電子經緯儀量測概念與操作程序，並且與傳統教學方法相較之下，虛擬實境教學具有較好的互動效果，使得虛擬實境之教學成效優於傳統教學方法。

This study combines the virtual reality technology to develop a computer simulation tutoring system of non-contact-type electronic theodolite. This system can simulate the true electronic theodolite from horizontal correcting to the function of measuring, etc. It enables students to carry on interactive study in 3D virtual environment without worrying about safety and equipment damage. It can also improve students'' achievement.

This study includes systematic development and systematic evaluation. In the systematic development, the educative system utilizes 3D Studio Max (3DS) to create the scene of the virtual electronic theodolite. Then, the author constructs the operation interfaces with Visual Basic and EON software to offer an interactive scene picture to users. Finally, the interactive teaching of the virtual non-contact-type electronic theodolite is trained with the operation of the keyboard and mouse.

In the aspect of systematic evaluation, the results of learning experiment show that operating time and operating errors decrease with increasing the times of operation. Through the reliability experiment, it is proved that this tutoring system is reliable, so persons can have steady behavior in this tutoring system. In addition, an academic record of fictitious teaching is better than that of traditional teaching method. This is because fictitious teaching can offer clearer measuring conception and operation sequence.
