This volume contains the papers and posters selected for presentation at the First European Conference on Smart Sensing and Context (Euro SSC 2006) in Enschede, The Netherlands. Euro SSC 2006 was the ?rst conference of a series aiming at bringing together designers, engineers and researchers to explore two complementary viewpoints: – A device-centric, technology-drivenview: concerning intelligent sensors, s- sor networks and information processing for a new generation of networked devices and environments. – A service-centric, user-driven view: exploring architectures, techniques, and algorithms for context-aware and pro-active applications made possible by thedi?usionofambientcommunication, cooperatingobjects, andinteraction technologies. These subjects are active and relevant research areas in themselves, and there are several conferences that address them separately. Euro SSC 2006, however, considered them both, and especially the symbiosis between them, which we expect to result in very inspiring and interesting discussions, as well as new research ideas on how to combine them. The conference was organized in single tracks covering various issues ra- ing from intelligent sensors, sensor networks, context management and context awareness, andprivacy, toapplicationsandtestbeds. Organizingaconferencefor the ?rst time requires lots of preparations, such as ?nding a publisher, spons- ing organizations, and TPC members and most importantly attracting potential submitters. Fortunately, the amount and quality of the submissions were such that we were in the luxurious position to be able to accept only high quality and relevant papers. The conference attracted world wide attention and submissions came from ?ve continents. A total of 15 accepted full papers and 14accepted posters came from Asia, North America and Europe.
