Most advances in pervasive computing focus strongly on technological issues (e.g connectivity, portability, etc.); as technology becomes more complex and pervasive, design achieves a greater relevance Inadequate design leads to unnatural interaction that may overload users, hampering the old aspiration of creating transparent artifacts Transparency is a concept that describes technology that allows users to focus their attention on the main activity goals instead of on the technology itself Transparency is strongly related with the relevance of individuals' goals, their knowledge, and conventions learned as social beings This paper aims to provide a framework for the design of augmented artifacts that exploit users' knowledge about how things work in the world both in the syntactic and the semantic level.
