This book constitutes the refereed proceedings of the Third International Conference on Ubiquitous Computing, Ubicomp 2001, held in Atlanta, GA, USA in September/October 2001. The 14 revised full papers and 15 revised technical notes were carefully selected during a highly competitive reviewing process from a total of 160 submissions (90 paper submissions and 70 technical notes submissions). All current aspects of research and development in the booming area of ubiquitous computing are addressed. The book offers topical sections on location awareness, tools and infrastructure, applications for groups, applications and design spaces, research challenges and novel input, and output.

"...a must-read text that provides a historical lens to see how ubicomp has matured into a multidisciplinary endeavor. It will be an essential reference to researchers and those who want to learn more about this evolving field." -From the Foreword, Professor Gregory D. Abowd, Georgia Institute of Technology First introduced two decades ago, the term ubiquitous computing is now part of the common vernacular. Ubicomp, as it is commonly called, has grown not just quickly but broadly so as to encompass a wealth of concepts and technology that serves any number of purposes across all of human endeavor. While such growth is positive, the newest generation of ubicomp practitioners and researchers, isolated to specific tasks, are in danger of losing their sense of history and the broader perspective that has been so essential to the field’s creativity and brilliance. Under the guidance of John Krumm, an original ubicomp pioneer, Ubiquitous Computing Fundamentals brings together eleven ubiquitous computing trailblazers who each report on his or her area of expertise. Starting with a historical introduction, the book moves on to summarize a number of self-contained topics. Taking a decidedly human perspective, the book includes discussion on how to observe people in their natural environments and evaluate the critical points where ubiquitous computing technologies can improve their lives. Among a range of topics this book examines: How to build an infrastructure that supports ubiquitous computing applications Privacy protection in systems that connect personal devices and personal information Moving from the graphical to the ubiquitous computing user interface Techniques that are revolutionizing the way we determine a person’s location and understand other sensor measurements While we needn’t become expert in every sub-discipline of ubicomp, it is necessary that we appreciate all the perspectives that make up the field and understand how our work can influence and be influenced by those perspectives. This is important, if we are to encourage future generations to be as successfully innovative as the field’s originators.

Ubiquitous computing is coming of age. In the few short years of the lifetime of this conference, we have seen major changes in our emerging research community. When the conference started in 1999, as Handheld and Ubiquitous Computing, the field was still in its formative stage. In 2002, we see the Ubicomp conference (the name was shortened last year) emerging as an established player attracting research submissions of very high quality from all over the world. Virtually all major research centers and universities now have research programs broadly in the field of ubiquitous computing. Whether we choose to call it ubiquitous, pervasive, invisible, disappearing, embodied, or some other variant of computing, it is clear that Mark Weiser’s original vision has only become more and more relevant since the term was coined over 10 years ago. But, most important in our context, the interest in the field can be gauged from the rising number of full paper submissions to the conference: from about 70 in both 1999 and 2000, to 90 in 2001, to this year's record breaking 136! Counting technical notes, workshops, poster and video submissions, there were over 250 original works submitted to this year’s conference. This is an impressive effort by the research community, and we are grateful to everyone who took time to submit their work – without this, the conference would simply not exist.

This book constitutes the refereed proceedings of the 6th International Conference on Ubiquitous Computing, UbiComp 2004, held in Nottingham, UK in September 2004. The 26 revised full papers presented were carefully reviewed and selected from 145 submissions. The papers address all current issues in ubiquitous computing ranging from algorithmic and systems design and analysis issues to applications in various contexts.

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.

Written by a renowned author with more than 2,300 citations in Google Scholar, this book illustrates the challenges that ubicomp poses to our privacy. It outlines social, technical, and legal tools for coping with the ever-increasing digitalization of everyday life. The text provides rich background information on the social and legal constructs that surround privacy and data protection and offers a comprehensive overview of the various technical approaches used to give privacy and data protection in application areas, such as RED and location privacy.
