"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.
Sounds interesting, but what's the application for Disney? Another patent that reaps large licensing fees.
