This is a comprehensive and practical textbook on user experience design. Combining breadth, depth, theoretical contexts, and practical applications, this book takes a practitioner's process-and-practice approach, but grounds it in research and theory. The authors will guide readers through the UX lifecycle from process to design infrastructure, exploring steps and topics like conceptual design, design production, design thinking, prototyping, and agile UX methods. Students and practitioners will come away with knowledge and an understanding of how to create and refine interaction designs and ensure a quality user experience. Current HCI and User Experience (UX) books lack the breadth, depth, practical insights, and theoretical framwork that a new practitioner or consultant would need to get a whole-picture understanding of UX. Authors Hartson and Pyla combine their years of experience to guide readers through the UX lifecycle, from process to design infrastructure, exploring the important and necessary steps to ensure a quality user experience.  By the end of the book, readers come away with knowledge and an understanding of how to create and refine interaction designs. *Provides a robust ancillary package to enhance the UX learning experience. *Features real-world stories and contributions *Covers a range of applications for all kinds of interactions and devices
