User Modeling and Adaptivity in Nomadic Information Systems

Mobile/wearable computing and wireless multimedia communication enable new forms of user adaptive applications becoming popular in these days. In the following paper the hippie system as a prototype for the class of adaptive nomadic information systems is presented. The system builds a model about users preferences, knowledge, interests, and movements in physical space from the users movements and their usage of the interface. Beside the forms of adaptations already known from adaptive hypermedia, the system can adapt to the current user location. Furthermore the system can keep track of activities distributed over time and space, e.g., the preparation of an exhibition visit from home, the execution in the museum, and the evaluation of the visit from home again.
