Smart rooms provide advanced interfaces for networked information systems. Smart rooms include a variety of sensors that can analyze the behavior of persons in the room; these sensors allow people to issue commands without direct contact with equipment. Video is one important modality for smart room input--video analysis can be used for determining the presence of people in the room, gesture analysis, facial analysis, etc. This paper outlines the architecture of a real-time video analysis system for smart rooms. The system uses multiple cameras, each with its own video signal processor. We use algorithms that can be performed in real-time to capture basic information about the persons in the room.
