Nod is a ring that gives you the power to “move your world”

We can wear Google Glass on our head, a smartwatch on our wrist, and our smartphones can control just about everything else in the process. The one thing that is in common with all those things is that you have to hold or touch these things to get them to work.
Using Bluetooth Low Energy, Nod has its own app so you can trigger the shutter for your camera while comfortably holding your phone for the perfect selfie. There are apps to control Nest, GoPro, Roku, and the newer LG TVs.
Based on the compatibility list, Nod will work with a lot of different gear out of the box. From Belkin WeMo devices to Windows. Nod can also be enabled for proximity lock and unlock. Want to navigate Google Earth on your widescreen at home with just your hands? Nod. Control music? Nod. Nod has an open API, so developers can build (and have built) enabled apps that can control just about anything through gestures.
