Includes bibliographical references and index.

This book constitutes the refereed proceedings of the 5th International Conference on Ubiquitous Computing, UbiComp 2003, held in Seattle, WA, USA in Ocotber 2003. The 16 revised full papers and 11 technical note papers presented were carefully reviewed and selected from a total of 153 submissions. The papers are organized in topical sections on location and space, modeling and inference, context awareness, new devices and technologies, domestic environments and healthcare, social aspects and privacy, and new interfaces.
