----------------------- What is this book? What is not ------------------- ---- This book is interactive design: the design of the behavior of complex, user-focused interactive system, the method and principles used by the principles. The first part of this book focuses on the design process and system understanding of users. The second part provides strategic principles and tools. Part III in-depth study of tactical problems. This book does not attempt to propose a style guide or a set of interface standards. In fact, you will learn about why this tool is limited and can only work in a specific environment. That is, the processes and principles written in this book are compatible with your choice, and this book is a good reference book for any style guide. Style Guide longer than answering "What is", but in general, it is difficult to answer "why". This book is committed to answering questions in these interactive system designs. There are four main steps in designing interactive systems: research areas, understanding users, and their needs, defining the framework of the solution, filling design details. Many practitioners will join the fifth step: confirm that the test solution is valid for the user. They are not wrong. One step behind this is part of us to know the availability. It has been quite a lot of usability work, but the publication of interactive design is less. This book focuses on the process and principles of interaction design, does not involve the verification of the design plan, and many academic achievements in this field have been published. This book can be complementary to the method and practice of any availability engineering. You can harmoniously combine these two subjects to get the best design results.
