PREFACE

Some people watch birds. Others watch people. Some watch cars or boats, or sporting teams. I watch technology, especially the small, common, everyday variety. In particular, I watch the way people interact with technology. I am not happy with what I see. Much of modern technology seems to exist solely for its own sake, oblivious to the needs and concerns of the people around it, people who, after all, are supposed to be the reason for its existence.

The dehumanizing nature of modern technology has long been a theme for concern. My goal is neither to attack nor to defend, but to understand just how the interaction between human and technology takes place, to discover where and why difficulties appear, and then to try to do something about them. You might say that my goal is to socialize technology, to humanize technology.

Society has reached the point where it would be completely unable to function without technology. Our social judgments, our skills, and even our thoughts are indelibly affected by the nature of the technology that supports us. Worse, the impact is so pervasive, so subtle, that we are often unaware of how much of our beliefs have been affected by the arbitrary nature of technology.

These essays touch upon some of the critical issues. They are meant to inform as they amuse. Some are deliberately provocative. But I am serious about the main message: Technology tends to dehumanize. This is not a necessary part of technology, but it relentlessly encroaches upon us unless we exert caution. Technologists tend to create what technology makes possible without full regard for the impact on human society. Moreover, technologists are experts at the mechanics of their technology, but often are ignorant of and sometimes even disinterested in social concerns.

I believe that we can create a humane technology, one that serves and enhances people and society. But this won't happen unless educated, concerned people take a hand in the design and application of our technology. This book provides some starting points. It provokes, scolds, and speculates, all in the aim of increasing everyone's sensitivity to the dehumanizing aspects of technology, and the realization that we can cause it to be otherwise.

CHAPTER NOTES & BOOK DESIGN

Nothing seems to create more controversy about the design of a book than the placement of notes for each chapter. Academic readers are used to seeing notes at the bottom of relevant pages as footnotes. Trade publishers do not approve. They feel that notes distract, breaking the flow of reading. They prefer to hide the notes at the end of the book out of sight, but still available for the serious reader.

Many of my readers have complained vociferously. The notes are hard to find, they say, and it is particularly disruptive to keep two place markers, one for text, one for notes. Alas, I know of no data relevant to the relative proportion of readers who might fall into each category, the one described by the publishers or the one corresponding to those who write me. Each side argues that the other constitutes a tiny minority.

For this book, we are trying a compromise. Substantive comments have been put directly in the text: notes are used primarily for references and acknowledgments. I have kept substantive comments to a minimum. This should minimize the need to turn to a note. Each note specifies the chapter number, name, and page from which it has come, which a short quote from the text indicating the section to which it refers. This makes it easy to go from the notes back to the text, a feature many readers requested.

There still remains the question of how to tell the reader that there is a relevant note at the back of the book. Traditional footnote symbols are thought to be disruptive, diverting the reader's attention to the note, usually to find that it does not contain essential information. We are trying a more subtle signal, a simple mark in the page margin that signals a note associated with the page. The mark - * - appears in the outside margin. Substantive notes are signalled by doubling the signal: **

ACKNOWLEDGMENTS

I am grateful to many for their assistance and comments on these essays. My academic colleagues have provided much of my initial stimulation and my interactions with industrial developers and researchers have increased my appreciation for the difficulties of bringing technologies to the marketplace. I am grateful to all my colleagues:

I especially thank Mike Shafto and Ev Palmer at NASA Ames Research Center (who also support my research through the NASA Aviation Safety Program), my colleagues at Apple Computer Company and Digital Equipment Corporation, who have also helped support this research, and especially to Tom Erickson and Jim Spohrer at Apple for their comments on the manuscript. Julie Norman was a perceptive and properly critical reader of the early drafts. Bill Patrick at Addison-Wesley provided a useful scolding about the excesses of earlier drafts, telling me what was nonsense, helping me shape these essays into coherence, yet without losing either the fun or the message.

At the University of California, San Diego, Michael Cole continues to educate me about the nature of mind and culture, Edwin Hutchins has provided critical insights about the way that cognition is distributed over time, space, people, and things, and Hank Strub, Emmy Goldknopf, and Cyndi Norman kept plying me with critical readings, critiques, and queries, all to the eventual betterment of my own understanding. Comments have come from all over the world through the power of the electronic mail and bulletin boards that link the universities of the world (see, for example, Chapter 4, which was entirely the result of electronic mail interaction).

A book is a joint effort of many people. My experience has provided a wonderful example of how the interaction of cognition, technology, and social interactions can merge to aid human activity. Technology can be effective, supportive, and humanizing , if only we insist that it be so.
