What constitutes an identity, how do new technologies affect identity, how do we manage identities in a globally networked information society? The increasing div- sity of information and communication technologies and their equally wide range of usage in personal, professional and official capacities raise challenging questions of identity in a variety of contexts. The aim of the IFIP/FIDIS Summer Schools has been to encourage young a- demic and industry entrants to share their own ideas about privacy and identity m- agement and to build up collegial relationships with others. As such, the Summer Schools have been introducing participants to the social implications of information technology through the process of informed discussion. The 4th International Summer School took place in Brno, Czech Republic, during September 1-7, 2008. It was organized by IFIP (International Federation for Infor- tion Processing) working groups 9.2 (Social Accountability), 9.6/11.7 (IT Misuse and the Law) and 11.6 (Identity Management) in cooperation with the EU FP6 Network of Excellence FIDIS and Masaryk University in Brno. The focus of the event was on security and privacy issues in the Internet environment, and aspects of identity m- agement in relation to current and future technologies in a variety of contexts.

This fascinating cultural history of the personal computer explains how user-friendly design allows tech companies to build systems that we cannot understand. Modern personal computers are easy to use, and their welcoming, user-friendly interfaces encourage us to see them as designed for our individual benefit. Rarely, however, do these interfaces invite us to consider how our individual uses support the broader political and economic strategies of their designers. In Transparent Designs, Michael L. Black revisits early debates from hobbyist newsletters, computing magazines, user manuals, and advertisements about how personal computers could be seen as usable and useful by the average person. Black examines how early personal computers from the Tandy TRS-80 and Commodore PET to the IBM PC and Apple Macintosh were marketed to an American public that was high on the bold promises of the computing revolution but also skeptical about their ability to participate in it. Through this careful archival study, he shows how many of the foundational principles of usability theory were shaped through disagreements over the languages and business strategies developed in response to this skepticism. In short, this book asks us to consider the consequences of a computational culture that is based on the assumption that the average person does not need to know anything about the internal operations of the computers we've come to depend on for everything. Expanding our definition of usability, Transparent Designs examines how popular and technical rhetoric shapes user expectations about what counts as usable and useful as much as or even more so than hardware and software interfaces. Offering a fresh look at the first decade of personal computing, Black highlights how the concept of usability has been leveraged historically to smooth over conflicts between the rhetoric of computing and its material experience. Readers interested in vintage computing, the history of technology, digital rhetoric, or American culture will be fascinated in this book.

This textbook provides an introduction to the fundamentals of serious games, which differ considerably from computer games that are meant for pure entertainment. Undergraduate and graduate students from various disciplines who want to learn about serious games are one target group of this book. Prospective developers of serious games are another, as they can use the book for self-study in order to learn about the distinctive features of serious game design and development. And ultimately, the book also addresses prospective users of serious game technologies by providing them with a solid basis for judging the advantages and limitations of serious games in different application areas such as game-based learning, training and simulation or games for health. To cater to this heterogeneous readership and wide range of interests, every effort was made to make the book flexible to use. All readers are expected to study Chapter 1, as it provides the necessary basics and terminology that will be used in all subsequent chapters. The eleven chapters that follow cover the creation of serious games (design, authoring processes and tools, content production), the runtime context of serious games (game engines, adaptation mechanisms, game balancing, game mastering, multi-player serious games), the effects of serious games and their evaluation (player experience, assessment techniques, performance indicators), and serious games in practice (economic aspects, cost-benefit analysis, serious game distribution). To familiarize the readers with best practice in this field, the final chapter presents more than 30 selected examples of serious games illustrating their characteristics and showcasing their practical use. Lecturers can select chapters in a sequence that is most suitable for their specific course or seminar. The book includes specific suggestions for courses such as "Introduction to Serious Games", "Entertainment Technology", "Serious Game Design", "Game-based Learning", and "Applications of Serious Games".

The 1980s was the era when affordable computers came to UK homes. They were known as microcomputers as their 'brain' was a microprocessor chip. Before then, computers were either found in the IT centres of big companies, taking up a whole room, or were large desktop machines with a price tag that put them out of reach for most people. But in February 1980, a company called Sinclair Computers launched their first home computer costing less than GBP100 - the ZX80. It began a very exciting time for all those with an interest in technology, and the UK home computer market was born. The first Sinclair ZX80s were soon joined by a host of competition in the early years of the 1980s as machines were released from companies such as Acorn, Dragon, Tangerine and Commodore. They all wanted a share of a market that would soon be worth millions of pounds. This book explores the history of these companies and the entrepreneurs behind them such as Sir Clive Sinclair of Sinclair Computers and Chris Curry of Acorn Computers. The innovative machines they produced inspired a generation.
