How would you like to use your body as a screen and input device? Well, you will be able to do it in a very near future, according to the following video, which shows Skinput, the result of some experiments from researchers at Carnegie Mellon University and Microsoft’s Redmond research lab.

Skinput makes use of a microchip-sized pico projector embedded in an armband to beam an image onto a user’s forearm or hand. When the user taps a menu item or other control icon on the skin, an acoustic detector also in the armband analyzes the ultralow-frequency sound to determine which region of the display has been activated.
