A conceptual framework for end-user development in ambient intelligence

This paper proposes a conceptual framework for the design and continuous evolution of ambient intelligence environments. The framework is based on the metaphor of interconnection between humans and devices belonging to the intelligent environment. All actors are called on to perceive and act on the environment itself, giving rise to novel and unanticipated behaviors. To this aim, the proposed framework is structured along three layers - physical, inference and user - sharing an information space of events, conditions and actions. In particular, a EUD approach is advocated for the user layer to support ambient configuration and management and foster a smooth and progressive co-evolution of users and technologies.
