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 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)
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)
This paper describes the design and implementation of a natural language interface to a highly interactive space known as the Intelligent Room. We introduce a data structure called a recognition forest, which simplifies incorporation of non-linguistic contextual information about the human-level events going on in the Intelligent Room into its speech(More)
