Fujitsu debuted a new project at Mobile World Congress in Barcelona, that could potentially change the way we use our gadgets - specifically the way we touch our gadgets, by giving touch screens a flexible texture.

Fujitsu's prototype uses air: Ultrasonic waves, which are sound waves that are inaudible to us, vibrate the air over the screen. Air is a much more forgiving, flexible surface than the actual screen, so Fujitsu is able to vibrate the air in lots of different ways to provide different feedback. So the screen can feel bumpy, extra smooth, and slippery just by vibrating the air!

However, there hasn't been word on release date or price.
