![]() Look at it this way: You can divide people into their principal components. Will there be a backlash against technology? Not a backlash, but how much better off we'll be with tomorrow's human-centered systems depends on the individual. E-mail is not going to change thousands of years of socialization. Just because we have become interconnected, we have not acquired the right to bother other people with our writings, nor the obligation to respond to them. Ultimately, you and I have to change our attitudes and trash a lot of the mail we get. We have to start using metadata and XML to put labels on e-mail that describe what's in the e-mail messages so that we and our machines can select or reject the e-mail that comes in. I spend an average of 18 seconds on each e-mail, because I've set up push-button-action responses, but even so, I am only delaying the arrival of my total overload point. And you can only do a little bit by machine. Surely, people won't spend 15 hours a day on e-mail. That's a ridiculous time, and it will get 10 times bigger in the coming decade, as new users join and current users devote more time to e-mail. spend an average of an hour and a half a day on e-mail. We have to do something or we'll all drown in e-mail. You say we have to change our attitudes, too, and make them more human-centric. Ultimately, successful prototypes of human-centered systems will cause start-ups and big companies to go after the new forms. Microsoft has announced Hailstorm, a user-centered computer environment, as they call it, part of their. What will it take to cause commercial IT developers to embrace the concept of human-centric computing? It's already happening. We're starting to see a lot of start-ups in this area, and that's always an indication of a technology that's heating up. And a lot of work is being done in speech recognition. Carnegie Mellon University, Georgia Institute of Technology the University of Washington. It has for some time, first at the University of California, Berkeley. But work in human-centric systems goes on. #Speech we. the revolution softwareHuman-centric computing will take a shift in thinking, and it will take time for vendors to offer hardware and software that expresses it. It's what we already have, only more of it. ![]() How long before the transformation that lets us do this and more, simply by talking to a room? Pervasive computing is easy. Pervasive computing is beginning to be fact: With cell phones, laptops and handhelds, we can work pretty much anywhere. It will simply involve programs that sit there doing the things you want them to do. The software that serves you will not take human form like a robot, nor will it have a fuzzy face and big ears. It's one that is unsavory for humans but perfect for machines, and that is the many-dumb-servants model. Ironically, computing will follow an old model. They won't care how you communicate - whatever way is most comfortable for you. Remember, the fundamental thing that will set human-centered systems apart is that the computers will serve you. That's why human-centered systems need to have speech. Speech is natural for people, hence easy to use. Why? Much of it will involve speech understanding, not just speech activation. In the future computing model you describe, interaction will be speech-activated. Whether that calls for more or less stuff is secondary. ![]() By focusing on human-centered systems, we declare that our goal is to serve humans. If we make them more pervasive and use more of them, there will be that much more aggravation around us. Human-centric computing, however, focuses on the human. Pervasive computing implies a lot of equipment, where the focus is on a lot of devices that are themselves computers. How is that different from pervasive computing? There is a lot of confusion between pervasive or ubiquitous computing on the one hand and human-centric computing on the other. You talk about human-centric computing, in which the computer isn't a single device but a room where computing is around you and in the air. "That must be our goal." Computerworld writer Sami Lais interviewed Dertouzos about the future of computing. The future of computing lies in "making systems serve humans," he says. ![]() After 40 years of building computers, little has changed, says Dertouzos, the author of seven books, including his latest, The Unfinished Revolution: Human-Centered Computers and What They Can Do for Us (HarperCollins, 2001). Dertouzos, director of MIT's Laboratory for Computer Science. The Information Revolution won't fulfill its promise until we stop thinking as though we're still in the Industrial Revolution, according to Michael L. ![]()
