This book is primarily a summary of research done over 10 years in multimedia and virtual reality, which fits within a wider interest of exploiting psychological theory to improve the process of designing interactive systems. The subject matter lies firmly within the field of HCI, with some cross-referencing to software engineering. Extending Sutcliffe's views on the design process to more complex interfaces that have evolved in recent years, this book: *introduces the background to multisensory user interfaces and surveys the design issues and previous HCI research in these areas; *explains the basic psychology for design of multisensory user interfaces, including the Interactive Cognitive Subsystems cognitive model; *describes elaborations of Norman's models of action for multimedia and VR, relates these models to the ICS cognitive model, and explains how the models can be applied to predict the design features necessary for successful interaction; *provides a design process from requirements, user and domain analysis, to design of representation in media or virtual worlds and facilities for user interaction therein; *covers usability evaluation for multisensory interfaces by extending existing well-known HCI approaches of heuristic evaluation and observational usability testing; and *presents two special application areas for multisensory interfaces: educational applications and virtual prototyping for design refinement.

On February 1 2010 doctors told Alistair Sutcliffe's wife to say her final goodbyes to her husband who lay in an intensive care unit fighting for his life after suffering a massive brain haemorrhage. Remarkably, Alistair pulled through and this is the story of how his fight back from the brink of death became his hardest climb.

User-Centred Requirements Engineering: Theory and Practice reviews requirements engineering research and practice over the past 10 years. In this book, Alistair Sutcliffe introduces the field of Requirements Engineering, and describes a framework for RE research and practice to date. He explains the psychological background behind RE problems - providing some understanding about why RE is difficult and how human understanding can cause the problems we observe in getting requirements right. The book discusses communication and requirements analysis, and gives practical guidance for requirements elicitation, modelling and validation, along with details of a practical RE method for scenario-based requirements analysis and requirements for safety critical systems. Whilst primarily a research text for graduate courses, this book is also intended as a useful reference for practitioners who want an in-depth treatment of the subject to date.

This book explores the design process for user experience and engagement, which expands the traditional concept of usability and utility in design to include aesthetics, fun and excitement. User experience has evolved as a new area of Human Computer Interaction research, motivated by non-work oriented applications such as games, education and emerging interactive Web 2.0. The chapter starts by examining the phenomena of user engagement and experience and setting them in the perspective of cognitive psychology, in particular motivation, emotion and mood. The perspective of aesthetics is expanded towards interaction and engagement to propose design treatments, metaphors, and interactive techniques which can promote user interest, excitement and satisfying experiences. This is followed by reviewing the design process and design treatments which can promote aesthetic perception and engaging interaction. The final part of the chapter provides design guidelines and principles drawn from the interaction and graphical design literature which are cross-referenced to issues in the design process. Examples of designs and design treatments are given to illustrate principles and advice, accompanied by critical reflection.
