Methods of establishing a communications link using perceptual sensing of a user's presence

Abstract

A method of establishing a communications link uses automatic sensing of a computer user's presence and activity state to record user attributes in a form accessible to other computers in a communications network. Such automatic sensing may include keyboard/mouse monitors, cameras with associated image processing algorithms, speech detectors, RF radiation detectors, and infra-red sensors. Preferably, the attribute recording is done in a server process which can be accessed by other computer programs. A first application of this method is to inform persons at remote locations whether the party to be called is available to receive a call. A second application of the method is to use a Connection Agent to determine whether all desired participants for a conference, or at least a quorum of them, are present and available, so that the conference can be started. A third application of the method is to allow a called party to adjust the kind of notification, if any, he or she receives of an incoming call, depending upon what activity is currently engaging the called party.
