Abstract
A dynamic information transfer system in which there are at least two targets , one of which is a mobile target and among which information can be transferred. The targets possess systems to store, process, and use information and programs in the form of an intelligent software agent (ISA) system associated with each target that is capable of initiating actions and negotiating with other agents or systems in the network. The ISA system includes a personal assistant device (PAD), or the like, that interacts with the user, and performs operations on the user's behalf. A Location Determination System (LDS) is utilized to determine the user's geographic position and the user's direction and speed of travel, if mobile. Virtual zones are used to trigger data transfers among the involved targets, events, or programs to be initiated or terminated at one of the involved targets. Virtual zones are bounded areas encompassing targets that are calculated dynamically from the location, direction, speed, and current or pending user activities associated with all involved targets. A User Profile is created and maintained either manually by the user or automatically by the user's PAD, and which specifies various user preferences related to such things as software programs, communications and messaging, entertainment, scheduling, and the degree of freedom and behavior of the PAD itself.
