(CNN) - Glass screens that can feel the touch of your fingers are all the rage in this Tagen.Sie see all kinds of gadgets from smartphones to Tablet PCs.

But the way a team from Disney researchers it looks there is a big problem with this technology: all glass screens feel exactly the same.

So, OK, the "problem" can not at night keep werden.Aber, considering the difference between typing on a hardware keyboard where you can feel if your fingers affecting right buttons are and a touch screen keyboard, where the letter "Q" and "w" exactly gleiche-- feel the space between them.

That is the problem, hope to solve the Disney research is a new technology it is calling "Tesla Touch."

This new type of touch screen this week was demonstrated for the first time at a Tech Conference in New York, uses a small static force control friction between a user's fingers and the touch screen.

"It's kind of like a buzz or a vibration."It has the same effect as a buzz ", Chris Harrison, said one of the Disney researcher and a graduate student at Carnegie Mellon University.""But if you carefully, optimize the frequency and vibration of the Panel you can actually create to feel that things like sandpaper or rubber or a wall."

In the case of a touch screen keyboard-like those on the Apple iPhone to the example-users would be able to position of the buttons feel and could learn to "touch" type without looking at your hands, he said.

If people on a file, drag it to a folder clicking, you would be able to feel the weight of the file and would know, by their sense of touch that had landed in the appropriate location, he said.Larger files like HD movies, also be made could seem to heavier than small files like text documents, said Harrison.

"A serious document such as one that is going to take longer to transfer will feel heavy," he said.

In contrast to other tests on the touch screen technology with "haptic feedback" or impulses to stimulate the sense of touch Tesla touch has used no movable Teile.Es small electrical Impulse--kind of like parties in static Cling--a pull and push between a person fingertip and the gadget screen to create.

Here are some of the nerdy details: the touch screen consists of three Schichten.Eine, topped with a transparent electrode platen glass and is an insulator, which simulate berühren.Um friction and texture, created the electrode small electric fields in the Isolationsschicht.Diese people fields oscillate between positive and negative charges, create these sensations.

Others have attempts to use vibrations, for example, compressed screen, touch-sensitive screens realistic Fühlen.Die BlackBerry storm and clicks when users successfully push on it.

But that does not allow that to touch users different parts of the screen and sensations, get different touch Harrison sagte.Das is possible with Tesla touch.

He said the Disney research technology which not, been commercialized übernommen.Ein was mobile in at least two prototypes was this week at a Conference of the Association for computing machinery, other touch screen table Disney research offices in Pittsburgh, Pennsylvania, working demonstriert.Eine.

Check out the project website for a demo video (bonus features include mysterious hands caress cat, pinching cloth and caress glassware).

If you feel especially studious, research has published an academic paper team, explains how all the tech works.

He said this technology is not the "magic bullet" that multitouch, tactile touch screens in the mainstream wird.Aber can move a step closer.
