Interaction Design

?This book has changed the world of a generation of students, educators and designers ? helping them to see life and technology in ways that inspire and inform appealing, delightful and effective interactive devices and services. Foundational knowledge and emerging topics are presented with virtuoso flair. It charms from the start: page after page you'll encounter stimulating, thoughtful wisdom written in a friendly, encouraging and empowering way. If you only ever buy one interaction design book in your life, this is the one: buy it and join the vital movement of person, community and society centred design that is building a bright future for billions of users worldwide.??Professor Matt Jones, Future Interaction Technology Lab, co-author of There's Not an App for That ? Mobile User Experience for Life (www.changetheworldUX.org) ?The 4th edition of Interaction Design, with its comprehensive and refreshing take on fundamentals of Human?Computer Interaction and integration in practice and recent research, sustains its status of first choice HCI course book in Namibia. The book is well-structured and content blended with plentiful case studies, activities and relevant and entertaining links which promote students? appreciation beyond their course work.??Dr Heike Winschiers-Theophilus, School of Computing and Informatics, Polytechnic of Namibia ?Interaction Design has always been my favorite textbook for all levels of education in HCI ? so much so it inspired the development of our new undergraduate and postgraduate programmes named after it. With this new edition it continues to be the most updated and accessible work available. As always, it captures state of the art in the field?s cumulative body of knowledge, and is a timely pointer toward new and emerging trends in interactive technology design and use.??Dr Jesper Kjeldskov, Professor of Computer Science, Aalborg University

Interaction design can be defined as designing interactiveproducts to support the way people communicate and interact intheir everyday and working lives. To be successful, interactiondesigners will need a mixed set of skills drawn from psychology,human computer interaction, web design, computer science,information systems, and entertainment as well as an understandingof the desires and needs of people and the kinds of technologyavailable. Interaction Design: beyond human computerinteraction offers a cross-disciplinary, practical andprocess-oriented introduction to the field, showing not just whatprinciples ought to apply to interaction design, but crucially howthey can be applied. The fourth edition of this best-selling textbook has beensubstantially updated to reflect this dynamic and fast-moving fieldand includes: Wiley e-text featuring videos and Q&A New chapter Interaction Design in Practice Coverage of many new and traditional interfaces 25 new talking-head videos with HCI experts answering questionslike has HCI gone too far? New section on emotional tech and automated emotion Coverage of AgileUX and the maker movement New sections on social interaction and social media Interaction Design is hugely popular with studentsand professionals alike. It is an ideal resource for learning theinterdisciplinary skills needed for interaction design,human computer interaction, information design, web design,and ubiquitous computing. Accompanying the text is an extensivewebsite at http://www.id-book.com whichcontains additional teaching and learning material including slidesfor each chapter, comments on chapter activities, and a number ofin-depth case studies written by researchers and designers.
