Abstract:
This paper explores the design, implementation and evaluation of context-aware mobile multimedia services by presenting six case studies on different application domains. The case studies highlight the opportunities that mobile devices equipped with wireless data transmission provide for context-aware and ubiquitous computing. Special emphasis is placed on empirical evaluation of the services in the field in form of a user evaluation with genuine end users in real environment of use. The paper concludes with a discussion on some important lessons learned from the case studies.
