A idéia de usar a pele enquanto interface não é nova, mas a forma como a máquina capta as informações é fascinante.

Esse é um trabalho do pessoal de Carnegie Mellon, uma faculdade foda, de onde sai as melhores coisas sobre jogos.

Researchers at Carnegie Mellon devised a new bit of tech magic that listed for the acoustic signals scattered through your arm when you tap it or your hand with a finger. The tech can then pinpoint exactly where you touched and translate that into useful input controls for a gadget.

The tech, which is in its very early stages, currently uses a bulky cuff, but researchers say it could be the size of a watch eventually. The device could also be built to work with a pico-projector, or perhaps a mobile phone with a built in projector, to cast the image of a screen onto your forearm or hand.
