Discovery of the potential role of sensors in a Personal Emergency Response System: What can we learn from a single workshop?

Capturing knowledge from domain experts is important to effectively integrate novel technological support in existing care processes. In this paper, we present our experiences in using a specific type of workshop, which we identified as a decision-tree workshop, to determine the process and information exchange during the usage of a Personal Emergency Response System (PERS). We conducted the workshop with current and possible future users of a PERS system to investigate the potential of context- and social awareness for such a system. We discuss the workshop format as well as the results and reflection on this workshop.
