Abstract

A good software is a software that is invisible for theuser. This is possible by making context explicit in thesoftware. The increasingly interest for the notion ofcontext appears through the number of approachesbased on it. Initially, context was mainly considered inEngineering and Cognitive Science. Now even inEngineering, one sees two sub-approaches consideringcontext at the level of the knowledge or the data, namelycontext-based and context-aware systems. For context-basedsystems, most of the non formal approaches focus,in one way or another, on context in relationships withthe user, aiming at a good computer system that isinvisible for the user. Context-aware systems areconcerned indirectly with users through a modeling oftheir dynamic environment. In this paper, we present,first, different viewpoints on context related to human-machineinteraction. We then consider why we need tofocus on users through two aspects, on the one hand, onplanning and plan execution, and, on the other hand,procedures and practice. The lesson learned is that animprovement of user's support needs a consideration ofcontext.
