"The idea is that we should have all our information services always available, no matter what we are doing, and as unobtrusive as possible. If I pick up your cell phone today and make a call, it charges you, not me. With our prototype H21s, when you pick one up and use it, it recognizes your face and customizes itself to you—it knows your schedule and where you want to be. You can talk to it, ask it for directions or make calls from it. It provides you access to the Web under voice or stylus command. And it can answer your questions rather than just giving you Web pages that you have to crawl through.
The E21s provide the same sorts of services in a pervasive environment. The walls become screens, and the system handles multiple people by tracking them and responding to each person individually. We are experimenting with new sorts of user interfaces much like current whiteboards, except with software systems understanding what you are saying to other people, what you are sketching or writing, and connecting you with, for instance, a mechanical-design system as you work. Instead of you being drawn solitarily into the computer’s virtual desktop as you work, it supports you as you work with other people in a more natural way....
In 10 years, we’ll see better vision systems in handheld units and in the wall units. This will be coupled with much better speech interfaces. In 10 years the commercial systems will be using computer vision to look at your face as you’re talking to improve recognition of what you are saying. In a few years, the cameras, the microphone arrays will be in the ceiling in your office and will be tracking people and discriminating who is speaking when, so that the office can understand who wants to do what and provide them with the appropriate information. We’re already demonstrating that in our Intelligent Room here in the A.I. Lab. I’ll be talking to you—then I’ll point, and up on the wall comes a Web page that relates to what I’m saying. It’s like Star Trek, in that the computer will always be available." [MIT Technology Review, via bOing bOing]
