FOURTHINTERNATIONALCONFERENCE ONUBIQUITOUSCOMPUTING SEPTEMBER29-OCTOBER1,2002 DRAKENCINEMAANDCONFERENCECENTER GÖTEBORG,SWEDEN PREFACE This volume is the adjunct proceedings of the UbiComp 2002 international conference on ubiquitous computing, collecting extended abstracts for posters, doctoral consortium, and video submissions. At this point in time, we already know that this year’s conference will be by far the biggest UbiComp yet, and the number of submissions in the different categories reflected this. Posters are a vital part of an academic conference, since they provide an opening for late- breaking and controversial work. They also provide an opportunity for researchers to discuss and test new ideas in an informal setting. We accepted a total of 27 posters for UbiComp 2002, spanning every imaginable area of UbiComp research and development, from telematics to user studies, from protocols for music sharing to ubiquitous computing in education. The poster abstracts are the first and by far the most substantial part of this volume. Doctoral students are important for the continued growth and development of the UbiComp research field. This year, we arranged the first UbiComp Doctoral Consortium, chaired by Anind Dey of Intel Research Berkley. The abstracts submitted by the doctoral consortium students comprise the second part of the adjunct proceedings. The video program was an innovative new part of this year’s conference, where we invited researchers and practitioners to submit videos that represented UbiComp research, new and old. We received a very high number of submissions and the video jury spent many hours viewing and commenting the videos. While the video program is mostly a "live" event, in the form of a screening of all selected videos at the UbiComp conference, several authors also chose to supply written abstracts. These comprise the final part of this volume.
