Check out the latest technology from Microsoft called Skinput. It’s an idea that may someday do away with a physical computer keyboard or remote control and replace them with your body! The video below shows how a projection system displays the keypad on a user’s arm, while sensors read the input based fingers touching skin.
The inventor explains applications for mobile devices and beyond, by using the human body as a sensor. Where does this technology go from here? I’m sure whatever consumers can do with a keypad now, they’ll someday be able to do with their bodies. Imagine snapping your fingers to unlock your front door, or using your forearm as a TV remote.
