When glass touch screens feel like sandpaper
|
This new type of touch screen, which was demonstrated for the first time at a tech conference in New York this week, uses a small static force to control friction between a user's finger and the touch screen. "It's kind of like a buzzing or a vibration. It has the same effect as a buzz," said Chris Harrison, one of the Disney researchers and a Ph.D. student at Carnegie Mellon University. "But if you carefully tune the frequency and the vibration of the panel you can actually create things that feel like sandpaper or rubber or a wall."
