摘要

國小教師常將立體幾何視為很簡單的教材，即使有完整的實體教具，也常礙於時間的關係而不能讓學童慢慢地操作模型。此外，在立體圖形的教學與測驗中，往往都是以平面的方式來表現立體圖形，造成空間概念不夠的學童無法理解，甚至害怕立體幾何。
因此，本研究針對國小幾何教學建置了一套基於擴增實境的互動式教學系統。利用深度攝影機易於追蹤身體部位的優勢，設計了以使用者自然的肢體動作為基礎的直覺化操作介面，讓學生可以在學習幾何的教室教學中，透過簡單有趣的人機互動產生學習興趣，進而在以肢體來操作虛擬模型的過程中得到即時的回饋。這套系統分為兩部分，分別為製作立體幾何模型的編輯器及提供學生參與互動式操作的播放器。在編輯器的部分提供教師快速製作幾何模型而不需要再學習過多的技術，而播放器讓學生可以對編輯後產生的模型作互動式的操作，並且在這個學習過程中經由教師的從旁協助與指導提升立體幾何的空間概念。

Teachers in elementary school usually use an easy way to teach solid geometry. Although there are sufficient resources of physical teaching aids, students usually cannot manipulate these models in a careful way due to the lack of time. Moreover, both the teaching and the test often represent teaching materials through two-dimensional style in the course, causing students low in spatial conception cannot understand or even refuse to learn in class.
Therefore, unlike traditional geometry education software whose operation interface still let students view and control flat shapes on the computer screen via two-dimensional actions, this study tries to build an interactive teaching system based on augmented reality according to elementary geometry education. This study use the depth camera with the robust capability of body tracking to provide an intuitive control method based on natural body action such that students in class can interact with the virtual object by their bodies. Moreover, this simple and interesting human computer interaction can bring the interest in the learning and then let students get the real-time feedback during the operation process. The system is divided into editor and player materials, respectively. The teacher can quickly create the geometry model without learning too many skills by using the editor. Students can interact with the object produced by the editor and raise spatial conception of solid geometry through the teacher’s guidance during this learning process.
