Activity monitoring and summarization for an intelligent meeting room

Intelligent meeting rooms should support efficient and effective interactions among its occupants. In this paper. we present our efforts toward building intelligent environments using multimodal sensor network of static cameras, active (pan/tilt/zoom) cameras and microphone arrays. Active cameras are used to capture details associated with interesting events. The goal is not only to make the system that supports multiperson interactions in the environment in real rime, bur also to have the system remember the past, enabling review of past events in an intuitive and efficient manner. In this paper, we present the system specifications and major components, integration framework, active network control procedures and experimental studies involving multiperson interactions in an intelligent meeting room environment.
