碩士 === 國立中央大學 === 資訊工程學系 === 103 === 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.
