Reviews

?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
