This is a comprehensive textbook on designing interaction to ensure a quality user experience. Combining breadth, depth, and practical applications, this book takes a time-tested process-and-guidelines approach that provides readers with actionable methods and techniques while retaining a firm grounding in HCI concepts and theory.

The authors will guide you through the UX lifecycle process, including contextual inquiry and analysis, requirements extraction, design ideation and creation, practical design production, prototyping, and UX evaluation. Development activities are linked via handoffs between stages as practitioners move through the process. The lifecycle template concept introduced in this book can be tailored to any project environment, from large enterprise system development to commercial products.

Students and practitioners alike will come away with knowledge and understanding of how to create and refine interaction designs to ensure a quality user experience.
