There has been some solid work done in the area of User-Centered Design (UCD) over the last few years. What's been missing is an in-depth, comprehensive textbook that connects UCD to usability and User Experience (UX) principles and practices. This new textbook discusses a theoretical framework in relation to other design theories. It provides a repeatable, practical process for implementation, offering numerous examples, methods, and case studies for support, and it emphasizes best practices in specific environments, including mobile and web applications, print products, as well as hardware.
