Nod

At this point you're used to gesture control on your devices — your smartphone, your tablet, the trackpad on your laptop — but true gesture-based communication with a device shouldn't rely on placing your hands on a surface. With Nod, gestures are freed from the confines of touch, letting you control just about any connected device by simply moving your hands in the air. By placing the ring on your finger, you can type without ever touching a keyboard, turn down the thermostat using your nest, even play a song on your phone without any physical contact. Made from jewelry-grade stainless steel, and available in a range of sizes to fit your finger, it uses Bluetooth connectivity to interact with a growing range of devices and technologies — you may never touch another device again.
