Cognitive Systems Engineering for User-computer Interface Design, Prototyping, and Evaluation

Chapter One Cognitive Systems Engineering in Perspective

This book seeks to answer the question: Can findings from cognitive science enhance the user-computer interaction process? The book recognizes that user-computer interfaces (UCIs) are often essential parts of an information or decision support system; in fact, UCIs are often critical components of software-intensive systems of all kinds. But we recognize from the outset that the design, prototyping, and evaluation of user-computer interfaces are part of larger systems and are therefore ideally designed, developed, and evaluated as part of a larger design and development process—or life cycle.

This book thus describes the process by which requirements—be they functional, nonfunctional, ...
