Researchers at Carnegie Mellon University and Microsoft have been collaborating to turn your body into a massive touchscreen called Skinput. The idea is similar to using a lazer keyboard projector and projecting things onto your skin, but Skinput goes further than that. According to Gizmodo, the CMU and Microsoft backed technology “recognizes which part of your body you’ve tapped, based on the sound that’s made on either the skin, muscle or skeleton. The wearer must strap on an armband containing piezoelectric cantilevers, or sensors that measure pressure, acceleration and force, with a pico projector similar to what’s found in phones beaming the interface onto the skin.”
The technology can have many applications and could be used as part of a natural interface for smartphones, laptops, games, and other experiences. It’d be interesting to see the return of the stylus after the capacitive touchscreen revolution so that users can make quick jots on their hands–just like the days of yore where you can do that with an actual ballpoint.
