In this book, we attempt to provide readers with effective and practical tools for interaction design. These tools consist of principles, patterns, and processes. Design principles encompass broad ideas about the practice of design, as well as rules and hints about how to best use specific user interface and interaction design idioms. Design patterns describe sets of interaction design idioms that are common ways to address specific user requirements and design concerns. Design processes describe how to go about understanding and defining user requirements, how to then translate those requirements into the framework of a design, and finally how to best apply design principles and patterns to specific contexts. Although books are available that discuss design principles and design patterns, few books discuss design processes, and even fewer discuss all three of these tools and how they work together to create effective designs. Our goal with this volume has been to create a book that weaves all three of these three tools together. While helping you design more effective and useful dialog boxes and menus, this book will simultaneously help you understand how users comprehend and interact with your digital product, and understand how to use this knowledge to drive your design. Integrating design principles, processes, and patterns is the key to designing effective product interactions and interfaces. There is no such thing as an objectively good user interface quality depends on the context: who the user is, what she is doing, and what her motivations are. Applying a set of one-size-fits-all principles makes user interface creation easier, but it doesn t necessarily make the end result better. If you want to create good design solutions, there is no avoiding the hard work of really understanding the people who will actually interact with your product. Only then is it useful to have at your command a toolbox of principles and patterns to apply in specific situations. We hope this book will both encourage you to deepen your understanding of your product s users, and teach you how to translate that understanding into superior product designs. This book does not attempt to present a style guide or set of interface standards. In fact, you ll learn in 14 why the utility of such tools is limited and relevant only to specific circumstances. That said, we hope that the process and principles described in this book are compatible companions to the style guide of your choice. Style guides are good at answering what, but generally weak at answering why. This book attempts to address these unanswered questions. We discuss four main steps to designing interactive systems in this book: researching the domain, understanding the users and their requirements, defining the framework of a solution, and filling in the design details. Many practitioners would

add a fifth step: validation, testing the effectiveness of a solution with users. This is part of a discipline widely known as usability. While this is an important and worthwhile component to many interaction design initiatives, it is a discipline and practice in its own right. We briefly discuss design validation and usability testing in 7, but urge you to refer to the significant and ever-growing body of usability literature for more detailed information about conducting and analyzing usability tests.

Much in the world of interface design has changed since the first edition of About Face was published in 1995. However, much remains the same. The third edition of About Face retains what still holds true, updates those things that have changed, and provides new material reflecting not only how the industry has changed in the last 11 years but also new concepts that we have developed in our practice to address the changing times. Here are some highlights of the major changes you will find in the third edition of About Face:

The book has been reorganized to present its ideas in a more easy-to-use reference structure. The book is divided into three parts: The first deals with process and high-level ideas about users and design, the second deals with high-level interaction design principles, and the third deals with lower-level interface design principles. The first part describes the Goal-Directed Design process in much greater detail than in the second edition, and more accurately reflects current practices at Cooper, including research techniques, the creation of personas, and how to use personas and scenarios to synthesize interaction design solutions. Throughout the book, we attempt to more explicitly discuss visual interface design concepts, methods and issues, as well as issues related to a number of platforms beyond the desktop. Terminology and examples in the book have been updated to reflect the current state of the art in the industry, and the text as a whole has been thoroughly edited to improve clarity and readability.
