This book contains the knowledge an interaction designer should know about pervasive design for sustainability. Relevant design research is discussed and framed in a story and value based participatory approach. Sustainability is the most important design goal. This is the first message. A second message is that information technologies, and in particular pervasive computing are invaluable keys in the quest for sustainability. Thirdly there is a lack of knowledge on sustainability issues in the interaction design community. In this book a unique meta-level framework structures an extensive discussion of design for sustainability. The framework is based on a principle of justice that is complemented by circumstances for sustainability chosen from the perspective of interaction design. We suggest and present the following circumstances: limited shared resources, socio-technical components and structures, technology development, vision and reflection, cognitive and behavioural support, joint ventures and political action. Topics discussed within the circumstances include experience design, ethics, Latours’s modes of existence, design fiction, computer games, futures studies, theories for reflection and behavioural change, personal informatics, and practice theory. The convolute concludes with a number of case studies where interaction design research is summarized and studied from the perspective of sustainability. We start out with thoughts on sustainable consumption, sustainable character, and the sustainable family that gets a section each. Adding to them are annotated case studies from research on design fiction, game and performance, value based design, practice theory, multi-level perspective design and design for a sustainable society. The book is a polyphonic convolute which means that there will be some overlap in the reports from the different discourses. Development in the areas related to interaction design can be sensed by identifying the surfacing themes. In total the e-book consists of the equivalence of 530 pages excluding references and index. Håkan Gulliksson is a lecturer on Interaction technology and Sustainable design at Umeå University for more than ten years.

A theory of place for interaction design.

Pervasive Information Architecture explains the 'why' and 'how' of pervasive information architecture (IA) through detailed examples and real-world stories. It offers insights about trade-offs that can be made and techniques for even the most unique design challenges. The book will help readers master agile information structures while meeting their unique needs on such devices as smart phones, GPS systems, and tablets. The book provides examples showing how to: model and shape information to adapt itself to users' needs, goals, and seeking strategies; reduce disorientation and increase legibility and way-finding in digital and physical spaces; and alleviate the frustration associated with choosing from an ever-growing set of information, services, and goods. It also describes relevant connections between pieces of information, services and goods to help users achieve their goals. This book will be of value to practitioners, researchers, academics, andstudents in user experience design, usability, information architecture, interaction design, HCI, web interaction/interface designer, mobile application design/development, and information design. Architects and industrial designers moving into the digital realm will also find this book helpful. - Master agile information structures while meeting the unique user needs on such devices as smart phones, GPS systems, and tablets - Find out the 'why' and 'how' of pervasive information architecture (IA) through detailed examples and real-world stories - Learn about trade-offs that can be made and techniques for even the most unique design challenges

We are living in the era of "Big Data" and the computing power required to deal with "Big Data" both in terms of its energy consumption and technical complexity is one of the key areas of research and development. The U.S. Environmental Protection Agency estimates that centralized computing infrastructures (data centres) currently use 7 giga watts of electricity during peak loads. This translates into about 61 billion kilowatt hours of electricity used. By the EPA's estimates, power-hungry data centres consume the annual output of 15 average-sized power plants. One of the top constraints to increasing computing power, besides the ability to cool, is simply delivering enough power to a given physical space. Green Information Technology: A Sustainable Approach offers in a single volume a broad collection of practical techniques and methodologies for designing, building and implementing a green technology strategy in any large enterprise environment, which up until now has been scattered in difficult-to-find scholarly resources. Included here is the latest information on emerging technologies and their environmental impact, how to effectively measure sustainability, discussions on sustainable hardware and software design, as well as how to use big data and cloud computing to drive efficiencies and establish a framework for sustainability in the information technology infrastructure. Written by recognized experts in both academia and industry, Green Information Technology: A Sustainable Approach is a must-have guide for researchers, computer architects, computer engineers and IT professionals with an interest in greater efficiency with less environmental impact. - Introduces the concept of using green procurement and supply chain programs in the IT infrastructure. - Discusses how to use big data to drive efficiencies and establish a framework for sustainability in the information technology infrastructure. - Explains how cloud computing can be used to consolidate corporate IT environments using large-scale shared infrastructure reducing the overall environmental impact and unlocking new efficiencies. - Provides specific use cases for Green IT such as data center energy efficiency and cloud computing sustainability and risk.

Interactive systems in the mobile, ubiquitous, and virtual environments are at a stage of development where designers and developers are keen to find out more about design, use and usability of these systems. Ubiquitous Computing: Design, Implementation and Usability highlights the emergent usability theories, techniques, tools and best practices in these environments. This book shows that usable and useful systems are able to be achieved in ways that will improve usability to enhance user experiences. Research on the usability issues for young children, teenagers, adults, and the elderly is presented, with different techniques for the mobile, ubiquitous, and virtual environments.

Drawing from existing theory, policy, practice and speculative design about how cities may evolve, the book illustrates key concepts using case studies that respond to the complex relationships between human and non-human others (such as animals and plants, as well as soil, rivers, data and sensors) in urban space.

This book constitutes the refereed proceedings of the Second International Conference on Online Communities and Social Computing, OCSC 2007, held in Beijing, China, July 2007 in the framework of the 12th International Conference on Human-Computer Interaction, HCII 2007. It covers designing and developing on-line communities, as well as knowledge, collaboration, learning and local on-line communities.
