I am not really sure if this is awesome or unnecessary, but here we go: Japan’s University of Electro-Communications has developed a small touchscreen that sends tactile information through the display onto the palm of your hand. In other words, it’s supposed to make you “feel” what’s going on on the screen.
The device looks pretty hacky at this point, but it apparently works. It has an electrical tactile display on the back that receives the tactile information from the touchscreen, for example when you push an icon on the display.
In the future, the makers see their device being used in mobile games, for example.
