Perceptive presence systems automatically convey awareness of user states to a remote location or application without the user having to perform explicit commands or mode selection. The article describes a component-based architecture for creating presence applications using perceptual user interface widgets. Each widget performs a machine perception function, such as tracking a face or monitoring activity in a specific 3D location. Widgets provide an abstraction barrier between the perception algorithms and the needs of application writers. Two example applications developed using this framework are presented: one uses a luminous display to express a user’s availability for communication to a colleague at a remote location, and a second uses activity to control devices in a context-aware environment.
