>>If you're always pressing the wrong icon on your smartphone touch screen, Japan's KDDI is working on a haptic screen that makes it feel like you're pushing a button instead of just a flat surface.
Prototypes shown off here at Ceatec 2011 respond to pressure and provide a sensation of clicking a keyboard button. The cellphone giant demoed potential applications including easier Web browsing and more interactive game playing.
