A tabletop lecture recording system based on gesture control

This research presents a lecture recording system that employs gestures and digital cameras to facilitate remote-distance teaching. The lecturer can teach in front of a desk or table, on which a Pan-Tilt-Zoom (PTZ) camera and a depth camera, i.e., Kinect, are installed. The lecturer can control the PTZ camera to record the teaching process by the gestures, which are designed as simple as possible so that the lecturer can focus more on explaining the course content, instead of the recording operations. The lecturer can write the notes easily on a paper or show the physical course material to enrich the lecture content. Digital slides can also be adopted when necessary to benefit the learning experience of students. Besides, the proposed system can help to reduce the effort/time for possible post video production.
