If our cars were as difficult to drive as our computers are to operate, they would never leave the garage. Yet everyday we put up with infuriating complications and incomprehensible error messages that spew forth from our technology: software upgrades crash our machines, Web sites take forever to download, e-mail overwhelms us. We spend endless time on the phone waiting for automated assistance.

In effect, we continue to serve our machines' lowly needs, instead of insisting that they serve us — a situation that will only get worse as millions of new mobile devices arrive on the scene.

Our world doesn't have to be this way. It shouldn't be this way.

Wouldn't it be great if using your computer was as effortless as steering your car? In The Unfinished Revolution, Michael Dertouzos introduces human-centered computing a radical change in the way we fashion and use computer systems that will ultimately make this goal possible.

The Unfinished Revolution is nothing less than an inspired manifesto for the future of computing. Dertouzos's vision will change how businesses, organizations, and governments work with each other, and how individuals interact. It represents the dawn of a new era in information technology.

Human-centered computing goes well beyond the empty promises of "user-friendly" interfaces. At its foundation are five key technologies that will dramatically amplify our human capabilities: natural interaction, automation, individualized information access, collaboration, and customization. Human-centered systems will understand us when we speak to them; will do much of our routine brainwork for us; will get us the information we want, when and where we want it; will help us work with other people across space and time; and will adapt on their own to our individual needs and desires.

By exploiting these five emerging technologies in combination — in our professional specialties and in our personal lives — we will see a vast increase in our productivity and a marked change in the ways we live and work. Human-centered technologies will make computers simpler, more natural, and more useful to us. The collective benefits of human-centered machines will give ordinary people capabilities that go beyond those enjoyed today by the most privileged. Human-centered systems will give us the gaspedal, brakes, and steering wheel of the Information Age.

When can all this happen? Dertouzos says the time to start is now. You can begin simplifying and improving your relationship with computers today. Dertouzos offers dozens of scenarios that illustrate the potential of human centered computing, as well as a preview of the MIT Oxygen project — a prototype now under development that aims to make pervasive human-centered computing a reality. Dertouzos also provides the new century's first glimpse of how upcoming information technology advances will significantly improve our lives and truly revolutionize our relationships with the computer.

This is a book for everyone, professionals and nonspecialists, who yearn for machines that live up to the grand promise of the Information Revolution — fulfilling real human needs with greater simplicity — that still lingers unfulfilled. The Unfinished Revlolution is for those who want to enhance their computer productivity and fun, in short, for every person who wants to do more by doing less.

Editorial Reviews

Our Review
A few hours before I started reading Michael Dertouzos's The Unfinished Revolution, I was furious, angry -- you might even say downright spitting mad. You see, my boyfriend and I, both with limited money and free time to spare, had decided to use our computer to create our Christmas cards. It seemed like an easy enough task until we attempted to print the address labels. The ZIP codes, although properly in place on our computer screen, refused to show up on the printouts. After running through about $50 worth of Avery sheets, I started plotting ways to throw the printer out the window, while my boyfriend cursed at the screen and repeatedly pressed the Control-Alt-Delete keys.

If you've ever had a similarly frustrating experience with your PC, not only will you love Dertouzos's latest work, you'll want to email passages of text to engineers and executives at every major computer, software, and networking technology company. You see, even Dertouzos -- who is more high-tech than most high-tech moguls and has pioneered countless technological developments as director of MIT's prestigious Laboratory for Computer Science -- can't figure out those automated voice mail systems that make you press 1 if you have a touch-tone phone and 7 to hear the instructions in Spanish. That's why his new book resonates for everyone. He shares all of our high-tech frustrations and argues that we must accept nothing short of human-centered computers.

"Once we change our mind-set in earnest," he writes, "we will no longer put up with the maddening computer faults we now suffer.... No longer will we be seduced by fancy buzzwords like 'multi-media,' 'intelligent agents,' 'push-versus-pull technologies,'...and a few hundred others already with us and yet to come."

The most refreshing thing about Dertouzos's new work is the fact that it never abandon's his "keep it simple" philosophy. He uses simple metaphors to help readers envision the creation of truly human-centric systems. (One of my favorites is an "e-bulldozer" that helps us with the overwhelming amount of "information shoveling" that we face every day.) The book's different sections present five human-centric forces -- speech understanding, automation, individualized information access, collaboration, and customization -- and clearly explain why the existence of all five is entirely plausible in the near future. Unlike so many business and technology books of the past five years, this is not a collection of pie-in-the-sky futurist hype. Instead, it's a common sense refashioning of our collective focus when it comes to technology.

If Dertouzos is at all guilty of futuristic fantasizing, it's in his argument for breaking down economic barriers and making computers available to individuals in the world's developing nations. "Imagine a new breed of useful counseling exchanges between the rich people of the West, who are often troubled by depression, divorce, and family problems, and the poor people of the East, who seem to counterbalance lack of money with strong family ties and inner peace." Although this reviewer is all for equal access to technology, it's hard to imagine, as Dertouzos suggests, that leveling the technology playing field will eliminate our need for psychotherapy and family counseling.

Despite such minor faults, The Unfinished Revolution will be a great start to your new year's reading. It will help you begin 2001 on an optimistic note. Instead of throwing that printer out the window or forcefully pressing Control-Alt-Delete, you'll want to join Dertouzos in finishing what is sure to be one of this century's most important revolutions.

In eight books, Dr. Michael L. Dertouzos—engineer, inventor, theoretician, and director of the Laboratory for Computer Science at MIT—predicted the many ways the information revolution would affect human lives.
Publishers Weekly - Publisher's Weekly
With wry humor and searing wit, the man Time magazine calls "MIT's #1 computer guru" disparages the high-tech devices (PCs, laptops, Web-friendly cell phones, hand-held digital organizersDwhat the author dismissively calls "weird animals") we've come to rely on so heavily but that often take forever to boot up, then crash and frustrate us to no end. (In a few years, he warns, there will be 10 times as many of these "creatures biting at" us.) Enough is enough, says Dertouzos (What Will Be). Instead, he envisions a time when we alternate ample leisure with intellectually stimulating work, seamlessly integrated by technology that spares us the inconveniences of modern life. The key, says Dertouzos, is "human-centric computing," technological devices that "talk with us, do things for us, get the information we want, help us work with other people, and adapt to our individual needs... [that] truly serve us, instead of the other way around." These are not generic recommendations; the book discusses both the existing technology and what is needed to bring it up to human-centric standards. It then offers a five-pronged approach that takes into account "both the human and computer sides of the relationship." A weakness in Dertouzo's argument, however, is the lack of discussion of competing design views or past failures in implementing these ideas. Human speech interaction, in particular, has been controversial since the 1960s and has occasioned many expensive flops; there is also a school of thought that early adopters have consistently preferred cutting-edge features to user-friendly ones. Still, the book is a readable and sensible application of design principles to computer technology, written at a level accessible to nonprofessionals. Agent, Ike Williams.

Chapter One

Why Change

Weird animals surround me in my home, at work, everywhere I go. Every day I must spend hours feeding them, healing them, waiting for them. And the fighting! They hold each other hostage in asphyxiating headlocks. I scream at them, but they just grunt or stare back stupidly. When we do get along, and I'm feeling affection for them, they suddenly turn around and bite a chunk off my hide.

You are surrounded by these creatures, too — the personal computers, laptops, handheld assistants, printers, Internet-savvy phones, music storage drives, and other digital wonders. They are everywhere and multiplying fast. Yet instead of serving us, we are serving them. We wait endlessly for our computers to boot up, and for bulky Web pages to paint themselves on our screens. We stand perplexed in front of incomprehensible system messages, and wait in frustration on the phone for computerized assistance. We constantly add software upgrades, enter odd instructions, fix glitches, only to sit in maddening silence when our machines crash, forcing us to start all over again, hoping against hope that they didn't take a piece of our intellectual hide with them. We'd never live in a house, work in an office, or ride in a car where we had to put up with a menagerie of such beasts. Yet we do it every day with our computer menagerie.

We shouldn't have to.

We have already gone so far down the road of serving computers that we've come to accept our servitude as necessary. It isn't. It is time for us to rise up with a profound demand: "Make our computers simpler to use!" Make them talk with us, do things for us, get theinformation we want, help us work with other people, and adapt to our individual needs. Only then will computers make us productive and truly serve us, instead of the other way around.

Is this possible? Certainly.

Before I reveal an entirely new approach to computer systems and their uses — a new plan for human-centric computing — let me assure you that in our new century, we have every right to expect fundamental reform. For 40 years computers have been shrines to which we pay dutiful homage. When something goes wrong, the "user"you and I — feel that if we somehow had behaved better the trouble would not have arisen. But we are not at fault. The trouble lies in the current approach to computing.

If computers are to live up to the promise of serving us, they will have to change drastically and never again subject us to the frustrating experiences we have all shared.

Several colleagues from the MIT Laboratory for Computer Science and I are flying to Taiwan. I have been trying for three hours to make my new laptop work with one of these "smart cards" that plug into the machine and download my personal calendar. When the card software is happy, the operating system complains, and vice versa. Irritated, I turn to Tim Berners-Lee, sitting next to me, who graciously offers to assist. After an hour the inventor of the Web admits that the task is beyond his capabilities. I turn to Ron Rivest, inventor of RSA public key cryptography, and ask him to help. He declines, exhibiting his wisdom. A young faculty member behind us speaks up: "You guys are too old. Let me do it." He gives up after an hour and a half. So Igo back to my "expert" approach of typing random entries into the various wizards and lizards that keep popping up on the screen. After two more hours, and two batteries, I make it work, by sheer accident and without remembering how.

My friends on this flight were hardly incompetent. The problem was what I call the "unintegrated systems fault." Technologists design today's hardware and software systems without worrying enough about how these different pieces will work together. If the slightest conflict arises among an operating system, a communications network, a digital camera, a printer, or any other device, the modules become deadlocked, as do their makers, who point to one another, leaving you to resolve their differences. After I published this Taiwan anecdote in an August 1999 article in Scientific American, I received scores of letters from people who said, "I know exactly what you are talking about. Please fix it." The problem is not simply a "bug" to be worked out in existing systems, but rather an endemic mind-set that has characterized computer design for decades. Only a radical change can fix it.

It's 11 P.M. and I check my e-mail. Ninety-eight new messages have arrived since yesterday. At 2 to 3 minutes per message, my average response time, I'll need 4 hours to handle them. I'd like to grant them my highest security classfication, DBR — "destroy before reading."

How do we handle this "overload fault?" We don't. Mostly, we feel guilty if we cannot respond to all the messages that come our way. Better e-mail software can relieve a lot of this burden. Better human behavior can go further. Human-centric computing means more than changing the hardware and software of computer systems. We must also improve the ways we use technology.

My son is searching the Web for information on Vespas, the Italian scooters that conquered Europe in the 1950s, which he loves to restore. The search engine has given him 2,545 hits and he is busy checking them out. His eyes squint and his brain labors to minimize the time he needs to decide whether he should keep or toss each entry. I imagine him in an ancient badlands, furiously shoveling through 2,545 mountains of dirt, looking for one nugget of hidden treasure. His shovel is diamond studded and it is stamped "high tech," so he is duly modern. Yet he is still shoveling!

Meet the Author

Tech oracle Michael Dertouzos (1937-2001) offered a learned, accessible, and fascinatingly detailed preview of new information technology and described how it would remake our society, culture, economy, and private lives.

Since 1974 Michael Dertouzos had been Director of the MIT Laboratory for Computer Science (LCS). For more than a quarter century, MIT has been at the forefront of the computer revolution. Its members and alumni have been instrumental in the invention of such innovations as time-shared computers, RSA encryption, the Spreadsheet, the NuBus, the X-Window system, the ARPAnet and the Internet. The Lab is currently home to the World Wide Web Consortium, an open forum of companies and organizations led by the Web’s inventor.

Dertouzos had spent much of his career studying and forecasting future technological shifts, and leading his lab toward making them a reality. In a 1976 People magazine interview, he successfully predicted the emergence of a PC in every 3-4 homes by the mid-1990s. In 1980, he first wrote about the Information Marketplace, with an ambitious vision of networked computers that has emerged as the trillion-dollar engine of commerce transforming our economy.

Most recently, Dertouzos has been an advocate for what he calls "human-centric computing" — a radical transformation of the way we use computers. As part of this effort, LCS recently unveiled the $50 million Oxygen project, intended to make computers easier to use and as natural a part of our environment as the air we breathe.

Born in Athens, Greece, Dertouzos came to the U.S. as a Fulbright Scholar. Following a Ph.D. from MIT in 1964, he joined the MIT faculty, where he had been Professor of Computer Science and Electrical Engineering.

In 1968 Dertouzos founded Computek Inc. to manufacture and market one of the earliest graphical display terminals, based on one of his patents. He soon became the Chairman of the Board of Computek, where he introduced the first intelligent terminals in the early 1970's. He subsequently sold the company when he became Director of LCS. Since that time, Dertouzos has been involved in several high-tech start-ups, including Picture Tel and RSA. In his consulting activities for companies such as Siemens Nixdorf, UPS, and BASF he has advanced business and Information Technology strategies.

During the Carter Administration, Dertouzos chaired a White House advisory group that redesigned the White House Information Systems. In February of 1995, he represented the U.S. as a member of the U.S. delegation led by Vice President Al Gore to the G7 Conference on the Information Society. In 1998 he was co-chairman of the World Economic Forum on the Network Society in Davos, Switzerland.

Dertouzos was a dual citizen of the U.S. and the E.U. He had worked extensively with the European Commission, in particular as a frequent keynote speaker on ESPRIT and other EC technology programs. For several years he was an adviser to the Prime Minister of Greece, as well as to other governments.

Dertouzos was also a member of the United States National Academy of Engineering and the Athens Academy of Arts and Sciences. He held an honorary doctorate from the University of Athens, and he received the B.J. Thompson Award (best paper) of the Institute of Electrical and Electronics Engineers (IEEE) and the Terman Award (best educator) of the American Society for Engineering Education. He was a member of the U.S. Council on Foreign Relations, and has been honored by the Hellenic Republic as Commander of Greece's Legion of Honor.

Dertouzos is the author/co-author of seven books, including MADE IN AMERICA: Regaining the Productive Edge (MIT Press, 1989), with over 300,000 copies in print, and WHAT WILL BE: How the New World of Information Will Change Our Lives (HarperCollins, 1997), which has been translated into thirteen languages.
