Context-aware systems

Abstract

Based on the assumption that the scarce resource for many people in the world today is not information but human attention, the challenge for future human-centered computer systems is not to deliver more information "to anyone, at anytime, and from anywhere," but to provide "the 'right' information, at the 'right' time, in the 'right' place, in the 'right' way, to the 'right' person."
