    Abstract: 本論文實作簡易桌面式教學輔助系統,藉由手勢判斷與PTZ攝影機的結合,簡化授課教師於錄製授課影片時,在不同情境下對授課教材的操作,讓課程錄影的過程更為順暢、直觀且具有彈性。本機制讓授課教師方便地在桌面上書寫教學內容,並自行操作PTZ攝影機拍攝課程筆記或講義,也可將書本與相關資料之文字與圖片等實體教材加入於課程中以豐富教學內容。授課教師可選擇使用投影片進行教學,同時以桌面手寫的方式對課程內容進行說明。此外,本機制盡量透過簡易的手勢達成需要的PTZ攝影機操控,降低教學錄影的複雜度,讓授課教師將心力專注於課程講解。
    ;A desktop course recording system is presented in this thesis. We combine the gesture control and operations of a PTZ camera to simplify the recording of lectures. To facilitate the recording process, the lecturer can easily write the lecture note on a paper or show the course material to enrich the content of course. In addition, the lecturer can also teach with the course slide. The proposed mechanism targets at controlling the system by gestures as simple as possible to reduce the complexity so that the lecturer can focus more on explaining the course material during the course recording.
    To achieve the functions mentioned above, we employ the depth camera, i.e., Kinect, to reliably detect the lecturer’s gestures and the PTZ camera to record the course content. The lecturer can use several gestures to control the PTZ camera according to different situations. Considering that the lecturers may have various backgrounds, we not only simplify the system setting but also make the gesture commands stable and intuitive. This system can thus reduce the cost of labor and time for the post video production. The ultimate goal is to enable more learners willing to use the system to record videos for remote distance learning, so that more students can benefit from such a learning experience.
