TeslaTouch lets your fingers actually feel what the screen shows. When you move a file on the screen with your finger, you can feel how big it is. Because TeslaTouch can provide a wide variety of tactile(or haptic) sensations such as textures, friction and vibration, Disney calls it the “future of feel.”

The technology is based on the electrovibration principle, which can programmatically vary the friction between sliding fingers and a touch panel. This technology requires no moving parts, unlike most modern-day tactile feedback devices, which use various mechanical actuators.
you can actually feel with your fingers what the screen shows. This could be an object texture, feeling of the paint or weight of the file. Or perhaps imagine a flat touch keyboard where the virtual keys can be actually felt.
