Services in Context

The paper gives an overview of a recently started research project addressing the question:Can context be exploited to add value to IT-services?Beyond today's way-finding services based on GPS and maps,we believe there is a new class of context-aware pervasive services making good use of a broad range of context information(e.g.identity,time of day,temperature,history as well as relative location of friends and belongings).Last but not least we believe one can find ways of adding value to IT-services by using disembodied conversational agents based on voice,sounds and visual signals integrated into the environment, instead of being guided by explicit directions shown on a display.The project aims at giving both new fundamental insight about the theory behind IT-services,their architecture and user interfaces and at building a number of prototypes demonstrating innovative context-aware pervasive IT-services.
