This paper describes design criteria for creating highly embedded, interactive spaces that we call Intelligent Environments. The motivation for building these systems is to bring computation into the real, physical world to support what is traditionally considered non-computational activity. We describe an existing prototype space, known as the Intelligent(More)
Intelligent Environments (IEs) have specific computational properties that generally distinguish them from other computational systems. They have large numbers of hardware and software components that need to be interconnected. Their infrastructures tend to be highly distributed, reflecting both the distributed nature of the real world and the IEs' need for(More)
We present a novel methodology for building highly integrated multimodal systems. Our approach is motivated by current cognitive and behavioral theories of sensory perception in animals and humans. We argue that perceptual integration in multimodal systems needs to happen at the lowest levels of the individual perceptual processes. Rather than treating each(More)
We describe a bottom-up approach to the design of software agents. We built and tested an agent system that addresses the real-world problem of handling the activities involved in scheduling a visitor to our laboratory. The system employs both task-specific and user-centered agents, and communicates with users using both email and a graphical interface.(More)
