This New 'Skinterface' Could Make Smartwatches Suck Less
If smartwatches are going to create a gadget future beyond smartphones, they'll have to up their game . Researchers from Carnegie Mellon may have just the thing with a new smartwatch interface that uses that fleshy bezel right next to the typically tiny displays: your arm. Called SkinTrack, this "whoa future" idea comes in two parts, a wristband laden with electrodes and a ring that emits a high-frequency AC signal. That signal then propagates through the skin, and the high-tech wrist band approximates its location. And just like that, a skinterface. The tech also works through clothing as well, and if you think bulky smart rings are dumb, just know the tech industry disagrees with you.
