摘要

在工程教育中，三維空間認知學習佔有重要的地位。然而多數實際教學僅提 供二維圖片或文字描述來闡釋三維空間概念。過去的研究推薦以擴增實境(AR) 來解決這方面問題，且已證實該技術能夠輔助學生在三維空間概念相關的科目的 學習，並透過提升教學互動提升學生學習動機。過去致力於 AR 技術於教學之應 用系統與設備之研究多以評估學生學習成效較多，而通用的應用框架卻較少。因 此，本研究提出一個基於圖形跟蹤之 AR 教學應用的概念框架，供未來應用 AR 技術於教育做參考。本概念框架包含三個模組分別是 AR 圖形跟蹤器模組、AR 互動模組、以及 AR 檢視模組。該三個模組是經由已回顧的文獻中所歸納的 AR 互動教育應用常用模組。在本研究中，設計了一套基於圖形追蹤器之 AR 互動教 育應用程式的原型，其中包含網頁、可攜帶裝置應用程式、以及資料儲存庫。該 應用程式原型測試於教室互動、自學、以及實驗室等三種不同的教育情境。在三 種測試情境中，教師透過網頁準備教材，學生透過應用程式增加學習成效。經過 測試得出:選用圖形做為 AR 之追蹤器可減輕教師導入 AR 教材的工作量;應用 程式能夠提升學生對三維空間的認知，並能促進學習動機。

Education is always one of the essential topics in all fields in the world. The engineering education contains lots of 3D implementing practices which require spatial abilities while most of the courses only provide 2D diagrams for students to learn 3D scenarios. The augmented reality (AR) has been suggested to implement into education for decades to improve the learners’ spatial abilities and the motivation of learnings. However, most of the AR learning implementations result in more instructor’ preparation which usually needs the technical skill of developing. In order to implement AR in education, this research proposed a conceptual framework of the pictorial tracker-based AR into engineering education. This framework provides the implementation levels of different needs and lowering the thresholds of technical skill. This framework utilizes three phases: 1) the pictorial tracker-based AR module, 2) the AR interaction module, and 3) the AR viewer module. This research suggests that both the instructors and the learners need the user interface to ultimate the pictorial tracker- based AR application. The prototype application is designed in this research and is implemented in three kinds of scenarios as demonstrations, in-class lectures, self- learning with textbooks, laboratory courses. Through the demonstrations, this research concludes two concepts: using the pictorial tracker as AR tracker can reduce the workload of instructors while importing AR technology; the application can enhance students' perception of 3D space and promote learning motivation.
