"…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 TechnologyFirst 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 measurementsWhile 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.

This book presents fundamental new techniques for understanding and processing geospatial data. These "spatial gems" articulate and highlight insightful ideas that often remain unstated in graduate textbooks, and which are not the focus of research papers. They teach us how to do something useful with spatial data, in the form of algorithms, code, or equations. Unlike a research paper, Spatial Gems, Volume 1 does not focus on "Look what we have done!" but rather shows "Look what YOU can do!" With contributions from researchers at the forefront of the field, this volume occupies a unique position in the literature by serving graduate students, professional researchers, professors, and computer developers in the field alike.

nd These proceedings contain the papers presented at the 2 International Workshop on Location- and Context-Awareness in May of 2006. As computing moves increasingly into the everyday world, the importance of location and context knowledge grows. The range of contexts encountered while sitting at a desk working on a computer is very limited compared to the large variety of situations experienced away from the desktop. For computing to be relevant and useful in these situations, the computers must have knowledge of the user’s activity, resources, state of mind, and goals, i.e., the user’s context, of which location is an important indicator. This workshop was intended to present research aimed at sensing, inferring, and using location and context data in ways that help the user. Our call for papers resulted in 74 submissions, each of which was assigned to members of our Program Committee. After reviews and email discussion, we selected 18 papers for publication in these proceedings. Most of the accepted papers underwent a shepherding process by a reviewer or a member of the Program Co- ittee to ensure that the reviewers’ comments were accounted for in the published version. We feel our selective review process and shepherding phase have resulted in a high-quality set of published papers. We extend a sincere “thank you” to all the authors who submitted papers, to our hard-working Program Committee, our thoughtful reviewers, and our conscientious shepherds.

The Ubiquitous Computing conference series provides the premier forum in which to present original research results in all areas relating to the design, implementation, app- cation and evaluation of ubiquitous computing technologies. It is a well-established platform to introduce and discuss research that enables new capabilities, appropriate security and privacy, improved user experiences and simplified and powerful devel- ment and deployment practices. These proceedings contain the papers presented at the Ninth International Conf- ence on Ubiquitous Computing (UbiComp 2007) in Innsbruck, Austria, in September 2007. Our call for papers resulted in 150 submissions, each of which was assigned to a primary and a secondary member of our Program Committee. Every primary and secondary member was responsible for assigning one or more additional qualified reviewers with specific expertise in the field. After double-blind reviews and an online discussion, we had a two-day face-to-face meeting with 38 of the 40 Program C- mittee members attending the PC meeting held just before the Pervasive 2007 conf- ence in Toronto, Canada, in May 2007. We are grateful to Khai Truong , Jeremy Knight and Alex Varshavsky of the University of Toronto for providing facilities and support for this meeting. At the PC meeting, about 80 of the submissions were in- vidually and extensively discussed in one of the three subgroups sensors, experiences and systems as well as in the calibration and decision panels. The PC finally selected 29 papers for publication in these proceedings.

Spatial gems are computational techniques for processing spatial data. This book, a follow-up to the first Spatial Gems volume, is a further collection of techniques contributed by leading research experts. Although these approaches were developed by their authors as part of larger research projects, the gems represent fundamental solutions that are generically applicable to many different problems. Our goal is to expose these useful techniques that are not yet in textbooks and often buried inside technical research papers to share them with software developers, graduate students, professors, and professional researchers.
