Download or read book User Centered System Design written by Donald A. Norman and published by Hillsdale, N.J. : L. Erlbaum Associates. This book was released on 1986 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about the design of computers from the user's point of view. The emphasis is on people, rather than the technology. This book is about the directions in which computers must move. This is a book of ideas, of analytical techniques described for their purpose, a book from which to derive the new questions in which design must move. The essays are pluralistic, offering a variety of perspectives, including the traditional study of human information processing structures, the subjective experience of the user and how to enhance it, and the social context of computing. The authors hope that the ideas discussed herein will lead to new kinds of interfaces--new, different, and more user friendly.
