This is an important thorough book. Guy Boy has presented a masterful review and synthesis of the many factors that affect how people and technology interact in the performance of a task, an understanding that is essential for those who design technology. I strongly recommend it for both students and professionals. -Donald A. Norman, Hewlett-Packard; author of The Invisible Computer If it is, as I have claimed that AI systems of the future will be less about artificial' intelligence and more about augmented' intelligence, Dr. Boy has produced a veritable handbook on the design of these cognitive prostheses. So sit down, relax, put on your ocular prosthesis and enjoy the read. -Ken Ford, Associate Director, NASA Ames Research Center This book is a significant first step towards making human-centered design a reality. It provides orientation and guidance for everyone who is concerned with developing systems that integrate people and computers in a context that provides functionality, reliability, flexibility, and responsibility. -Terry Winograd, Professor, Stanford University
