The tags assigned to RFID-identified objects in the environment can be used to enrich formalized domain-specific context-models with user generated keywords to take community- and user-generated meanings into account. These references in space help to navigate information and services about the identified objects and provide a source for adaptation. We’ve chosen the domain of fitness and health to build and evaluate a RFID-based software-prototype. This paper presents aspects of this work and reflects it on the theoretical background of context and context-awareness.enText/Conference Paper1617-5468
