Location and context awareness

Meer over het boek

Context-awareness drives the ubiquitous computing paradigm, with effective context modeling and retrieval being essential for context-aware systems. Location, alongside time, identity, and activity, is a fundamental aspect of major context models. The technical aspects of sensing, fusing, and distributing location and context information are crucial for delivering context-awareness in pervasive systems. The material summarized here was presented at the 1st International Workshop on Location- and Context-Awareness (LoCA 2005), held in conjunction with the 3rd International Conference on Pervasive Computing 2005. Organized by the Institute of Communications and Navigation of the German Aerospace Center (DLR) and the Mobile and Distributed Systems Group at the University of Munich, the workshop featured discussions on novel positioning algorithms and location sensing techniques. These included enhancements to existing systems, such as GSM and WLAN, as well as hybrid technologies that integrate global satellite systems with inertial positioning. The workshop also addressed advancements in sensor technology and the integration and fusion of sensors, both theoretically and practically. Additionally, the implications of personal and confidential data, particularly user location data, for privacy were explored, focusing on privacy protection and the impact of privacy on the feasibility and utility of location-aware systems.
