From Daily Mail:Those who find the touchscreens on their ever shrinking gadgets too fiddly to handle, will be glad to hear scientists are developing a new touch surface... your own arm.
Developers at Microsoft Research and Carnegie Mellon University are working together to create an armband that projects an interface directly on to your skin.
They have combined a mini projector which creates a changing display with a sophisticated sensor that can tell which part of your arm is being tapped.
The researchers showed Skinput can be used to control audio devices, play simple games like Tetris, make phone calls and navigate simple browsing systems.
The gadget effectively turns your arm into a touchscreen surface by picking up various ultra-low sounds produced when you tap different areas.
