Skinput Gadget, an arm Touchscreen Display

The dream come true! You may turn your arm to be a touchscreen display. How it comes?

Developers at Microsoft Research and Carnegie Mellon University were now been in a great project. They 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.

And it is effectively turns your arm into a touchscreen surface by picking up various ultra-low sounds produced when you tap different areas.

Different skin locations are acoustically distinct because of bone density and the filtering effect from soft tissues and joints. The team then used software that matched sound frequencies to specific skin locations.

If the prototype isn't resting on the arm, it uses wireless technology like Bluetooth to transmit the commands to the device being controlled, such as a phone, iPod, or computer. Currently, the acoustic detector can detect five skin locations with an accuracy of 95.5 per cent, which would be high enough for many smartphone applications.

The research claimed that the project is going well now and hope the product could be introduced 5 years later. Wow! Really great innovation! Nothing impossible in this era. And here are the video!
