The leading text in the field of human-computer interaction The field of interaction design is about designing interactive products and services to support the way people communicate and interact in their everyday and working lives. In particular, it involves applying knowledge and skills from many areas, including human-computer interaction, psychology, computer science, information systems and design to create transformative and immersive experiences. In the newly revised sixth edition of Interaction Design: Beyond Human-Computer Interaction, a team of distinguished UX and tech professionals delivers the latest, most up-to-date version of the gold standard in human-computer interaction references. The book offers a cross-disciplinary, practical, and process-oriented introduction to the field, showing readers the principles they should apply to interaction design as well as how to apply them. The authors demonstrate the interdisciplinary skills necessary for interaction design, human-computer interaction, information design, web design, and ubiquitous computing. An essential guide for interaction design professionals, the sixth edition of Interaction Design will also earn a place in the libraries of senior undergraduate and masters-level students of human-computer interaction, interaction design, web design, software engineering, and information studies. Accompanying the text is an extensive website at id-book.com which contains additional teaching and learning material. Full of revised, updated, and entirely new content, the book also provides: Explanations of the subject and process of interaction designDiscussions of the cognitive aspects of human-computer interactionExplorations of social and emotional interaction with machinesTutorials on data gathering, analysis, interpretation, and presentationExamples of design, prototyping and cognitive walkthroughsStudies of evaluation in controlled and natural settings “This updated volume of Interaction Design: Beyond HCI offers a solid overview of interaction design (IxD) and human-computer interaction (HCI). Whether you are a newcomer to IxD and HCI or an experienced researcher/practitioner looking for a refresher, this volume is your go-to reference text.” —Elizabeth F. Churchill, PhD, Senior Director, Google “Interactive technology underpins life for billions—keeping us entertained, keeping us alive and keeping us connected. Using the ideas, insights and inspirations in this book, lives can be transformed: made more enjoyable, safer, and fulfilled. A must-read book for students, researchers, and practitioners, written with passion, purpose and practical advice.” —Professor Matt Jones, University of Swansea
