Back in January, I profiled Mr. Raman, who has a long history of adapting technology to his needs. I thought the work on touch screens he was doing with Mr. Chen was intriguing:

Since he cannot precisely hit a button on a touch screen, Mr. Raman created a dialer that works based on relative positions. It interprets any place where he first touches the screen as a 5, the center of a regular telephone dial pad. To dial any other number, he simply slides his finger in its direction -- up and to the left for 1, down and to the right for 9, and so on. If he makes a mistake, he can erase a digit simply by shaking the phone, which can detect motion.
