George Roussos – författare

Every day we share encounters with others as we inhabit the space around us. In offering insights and knowledge on this increasingly important topic, this book introduces a range of empirical and theoretical approaches to the study of shared encounters. It highlights the multifaceted nature of collective experience and provides a deeper understanding of the nature and value of shared encounters in everyday life.Divided into four sections, each section comprises a set of chapters on a different topic and is introduced by a key author in the field who provides an overview of the content. The book itself is introduced by Paul Dourish, who sets the theme of shared encounters in the context of technological and social change over the last fifteen years. The four sections that follow consider the characteristics of shared encounters and describe how they can be supported in different settings: the first section, introduced by Barry Brown, looks at shared experiences. George Roussos, in the second section, presents playful encounters. Malcolm McCulloch introduces the section on spatial settings and – last but not least – Elizabeth Churchill previews the topic of social glue. The individual chapters that accompany each part offer particular perspectives on the main topic and provide detailed insights from the author’s own research background. A valuable reference for anyone designing ubiquitous media, mobile social software and LBS applications, this volume will also be useful to researchers, students and practitioners in fields ranging from computer science to urban studies.

At the core of this book is the interplay between technological and business innovation and social practice. Although the bene?ts of 50 years of rapid advances in digital telecommunications and computing technology have not bene?ted everyone equally, they have nevertheless transformed almost every aspectofthewaywelive.Oneareawheretechnologyhashada clearimpactis in the way we conduct business. The rate of change that brings about mod- nity has been considerably strengthened by technological advances applied to product manufacturing, distribution, ?nancing, and management, which arguably form the substrate for globalization and consumerism. It is thus no surprise that businesses closely monitor advances in techn- ogy and invest considerable resources in exploring possible new applications and market opportunities. Yet, consumers’ acceptance of new ways of buying and selling depends as much on business and technology as on our society’s culture and the culture of the material environment that de?nes our values, sensibilities, and thus our commitments. Moreover, the rate of technological innovation is such that to the c- sumer, technology implementation is fully opaque.Nonetheless, opportunities to carry out commerce in novel ways also introduce risk to established - cial structures, conventions, and institutions. In modernity, risk management is one of the core functions of society and to be successful in this, societies depend on their trust of experts. Experts take risks on behalf of society and are responsible for evaluating the full extent of a particular set of hazards including those associated with a particular technology.

The birth of RFID technology is credited to the 1948 research paper by H. Stockman on “Communication by Means of Re?ected Power” [109]. After describing the main principle of communication by re?ection and reporting his experiments, he concluded that “Evidently, considerable research and development work has to be done before the remaining basic problems in re?ected-power com- nication are solved, and before the ?eld of useful applications is - plored. ” It turns out that in fact this work required almost 60 years of science and engineering before it was mature enough to ?nd its way into large-scale - plications. This is surprising, as at ?rst glance RFID is a simple technology that is straightforward to implement. And yet, its dull appearance hides great complexity: RFID involves several engineering disciplines, including systems, networking and software development, antenna design, radio propagation, - tegratedcircuittechniquesincreasinglyfocusedonprintedelectronics,receiver design, encryption and security protocols, and materials technology, to m- tion but a few. In this book, I attempt to present the main ingredients for building c- plete network RFID systems, written for a knowledgable computing audience. I hope this book will help practitioners and researchers alike in establishing a robust framework for thinking about rfid. I also hope that the book will help anyone involved with rfid technology to make informed decisions that are appropriate for their particular problem at hand.
