Development of An e-Learning System for Quick Response Product Virtual Design and Presentation

[[abstract]]傳統上新產品的設計必須經常使用工藝手法與手繪草圖的方式，將產品製作成模型，再使用掃瞄技術將模型轉換成數位的CAD資料、或應用電腦繪圖軟體直接製成CAD模型資料，以利後續產品之原型製造與生產，此程序二度轉換產品原型相當耗時且流程繁雜。之後產品原型製作中，需購置昂貴的模具與機械加工機台生產與製作新產品，而提高新產品量產的成本。故本研究結合數位設計教學、虛擬模具組裝與機械加工實習工廠，並搭配網頁發佈的形式，建構出一套互動式虛擬實習環境提供學習。本研究將快速產品虛擬設計與展示之e化教學環境的課程應用在國立高雄第一科技大學大學部學生的學科與術科的教學上，並將學員分成：實驗組與控制組。實驗組施以虛擬實境電腦模擬教學；控制組施以傳統術科教學。在完成學習後，以學後測驗成績進行兩母體平均差的統計分析，結果實驗組的成績是優於控制組。學生與老師們在使用網路式虛擬教學軟體之學後成效評量，使用統計資料分析軟體作平均數的統計分析，分析結果：學生與老師們表示對此教學系統滿意度及可行性很高，對虛擬實境技術應用在教育訓練上皆持肯定的態度。[[abstract]]Traditionally, the design of a new product usually uses hand drawing to create the desired conceptual model for further digital scanning process in order to prepare for the final CAD modeling. In fact, it is possible to create a CAD model, which is able to make prototype for production, directly from commercial CAD software. Nevertheless, the entire process is not only long but demanding. In that case, the goal of this project is to design and implement a VR-based training-learning environment including virtual design, virtual manufacturing, virtual assembling, and virtual presentation for mold industry. Science and Technology Department of Mechanical and Automation Engineering of National Kaohsiung First University of has been using this system in technical teaching. The trainees in this research were divided into two groups：dependent group and independent group. The hypothesis has been proven by the fact that the DV group, receiving visual training, shows better understanding of the material and receives higher grades on the exams than the IV group, the group that receives normal training. As a result, this research points out that students and teachers have positive attitude toward the VR technique-applied teaching and training programs
