Abstract
Next Generation Ambient Intelligent Environments (NGAIEs) will offer intelligent and trustworthy services (although probably not for free), will be populated with Ambient Ecologies of smart objects, and will support the Activity Spheres of their multiple occupants. Ubiquitous computing applications will be composed from heterogeneous services offered by objects connected via the web and NGAIEs. These applications will inherently exhibit increasingly intelligent behavior, perceive the operational environment and adapt to it, provide optimized resource usage and support consistent functionality and human-centric operation. This paper tracks the disappearance of computers and the advent of Ambient Intelligence.
