Ontology-based context management components for service oriented architectures on wearable devices

Up-to-now wearable applications are built from individual optimized software components. This paper presents a structured approach to design and implement context-processing modules for context-aware systems and applications which significantly enhances reusability of this common component. Instead of monolithic, single purpose, context processing solutions, the authors suggest a generic approach to define contexts, and to employ a context management framework to realize the context-awareness services which complements the idea of an extensible wearable computing framework based on a service-oriented architecture developed by the European research project wearIT@-work.
