First published in the 1990s, About Face helped establish interaction design as a distinct discipline. It moved the practice out of research labs and into everyday product development. The fourth edition continues that mission with contemporary methods, updated examples, and a full color design that better illustrates modern concepts. At its core is Cooper’s renowned Goal-Directed Design methodology a systematic process that starts with understanding users’ goals rather than technical requirements or feature lists.

Practical chapters explore digital etiquette, platform and posture, optimizing for intermediate users, orchestration and flow, reducing unnecessary work (excise), and the thoughtful use of metaphors, idioms, and affordances. Special attention is given to preventing errors, informing better decisions, integrating visual design, and adapting principles across platforms desktop applications, mobile devices, and the web. The authors provide clear guidance on controls, dialogs, data entry, storage, and retrieval, helping designers create interfaces that feel natural and respectful of users’ time and attention.
What sets About Face apart is its focus on behavior. Interaction design is not just about how something looks; it is about how it acts. The book teaches designers to create products that support users’ goals with minimal friction, eliminate unnecessary complexity, and deliver experiences that feel almost invisible when they work well. These principles remain highly relevant in an era of apps, responsive design, and constantly evolving devices.
