About Face: The Essentials of Interaction Design

The fourth edition of the book that introduced personas and goal directed design to a wide audience. Its first part covers the process, moving through research, modelling users into personas, deriving requirements from scenarios, and framing an interaction design solution. The second part deals with behaviour and form, covering platform and posture, orchestration and flow, reducing the work a product demands of people, and designing across devices. The third part is a detailed catalogue of interface idioms covering controls, navigation, errors, notifications and data entry. Long, and used as a reference more often than read straight through.
