One famous research prototype of a sentient computing system was the work at AT&T Laboratories, Cambridge (now defunct).
The world model was managed via the SPIRIT database,[1] using CORBA to access information and spatial indexing to deliver high-level events such as "Alice has entered the kitchen" to listening context-aware applications.
The research continues at the Digital Technology Group at the University of Cambridge.
Some example applications of the system include: A context adaptive system typically enables the user to maintain a certain application (in different forms) while roaming between different wireless access technologies, locations, devices and even simultaneously executing everyday tasks like meetings, driving a car etc.
This involves making the navigation functionality available for different availability of output devices, input devices and location sensors as well as adapting the user interaction operability to the current speed, noise or operator handicaps while keeping in mind the overall applicability depending on the user preferences, his knowledge, current task etc.
