A widget based architecture for perceptive presence
Frank R. Bentley · DSpace@MIT (Massachusetts Institute of Technology) · 2003
In order to better create systems that use presence and awareness information, it is possible to create a general computer vision interface (identifying such concepts as blobs, position, and velocity, etc.) and set of widgets (identifying concepts such as Person Present, Spatial Selection, Gaze Selection, etc.) to accurately determine information about a person’s activity. A general interface can interface multiple computer vision systems to a layered stack of presence widgets that applications can rely on to obtain information about a given area. One such application, the Perceptive Presence Lamp, is currently running in the MIT AI Lab – linking two people together and allowing each one to see when the other is in, out, busy, or wanting to get their attention.
