A Prototype of a Context-Based Architecture for Intelligent Home Environments

This paper presents a proposal of a context-based architecture to achieve the required synergy among the ubiquitous computing devices of an intelligent environment. These devices produce context information that models the behaviour of the environment. This context information is the glue among the devices and the context-aware applications. The generated context information provides a common view of the world. A blackboard architecture allows to share this context information and a context model is proposed to represent it. A prototype of such a smart room has been developed, including several devices as well as a set of context-aware demonstrators. They work together employing the context information stored on the blackboard.
