A world in which computers are tinier than ever, but they will not be controled by keyboard or mouse. ABC's Deborah Amos has this report. We're used to controlling computers like this. . . But like this? "We believe that this is the first time that this technique has been used to fly an aircraft." A breakthrough in computer technology. This NASA scientist is piloting a computer simulated jet using only the muscles in his arm. "Where I make a gesture to pitch up, the aircraft pitches up." "You're controlling that." "Right, so, if I want to do a roll, I just hold my arm like it's going a roll and there it goes." It goes without a joystick or any other device. "We're beginning to get away from the idea of controlling machines with levers and knobs and moving more towards having the machines respond directly to our gestures and our thoughts." Here's what it means. When we type, when we click, when we use a joystick, there's a pattern to the way our arm muscles move. What the NASA scientists have discovered is you can do away with all this clumsy stuff because a computer can be taught to recognize muscle patters. The electrical signals from Kevin Wheeler's arm muscles are transmitted to a computer. "The computer recognizes that, and sends commands to the aircraft." A new way to command that could also work in outer space. NASA plans to test the muscle control with astronauts. And NASA scientists have wider applications in mind, a better way for surgeons to control small robotic devices now used in surgery. To better control a prosthetic arm through the working muscles of the handicapped. "We might have a computer the size of a pinhead and a keyboard the size of our hands." The first experiment is promising that soon we will be able to twitch a muscle rather than click a mouse. Deborah Amos, ABCNEWS, Mountain View, California.
