Typing on Skin

A new technology called “Skinput” uses bio-acoustic sensors to allow people to use the skin on their fingers or forearms — or any part of their bodies — as touchpads to control mobile devices. The technology could help people better use the computing power in the mobile devices they carry around with them every day by creating keyboards on the go, or larger touchscreens and jog wheels. “Our skin is always with us, and makes the ultimate interactive touch surface,” said researcher Chris Harrison.
