Abstract: Today, talks, presentations, and lectures are often captured on video to give a broad audience the possibility to (re-)access the content. As presenters are often moving around during a talk it is necessary to guide recording cameras. We present an automatic solution for user tracking and camera control. It uses a depth camera for user tracking, and a scalable networking architecture based on publish/subscribe messaging for controlling multiple video cameras. Furthermore, we present our experiences with the system during actual lectures at an university.
