The Essex intelligent dormitory (iDorm) is a practical ubiquitous-computing test bed environment that combines numerous heterogeneous computational artifacts and networks. A user occupied the iDorm for five and half days. During this period, an intelligent and adaptive embedded agent monitored and controlled the iDorm using the authors' fuzzy-logic-based Incremental Synchronous Learning (ISL) approach. The agent operates in a lifelong learning mode realizing the ambient-intelligence vision; it learns the user's behavior, adapts to his needs, and controls the iDorm according to the user's preferences in a personalized and nonintrusive way.
