Work funded by Disney Research is producing a technology called Tesla Touch where your touch screen activities will now have a certain touch and feel on your fingers.
"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."
In the case of a touch screen keyboard -- like those on the Apple iPhone, for example -- users would be able to feel the location of the keys, and could learn to "touch type" without looking at their hands, he said.
