Jealous of Harry Potter and his awesome magic wand, but would prefer it if you had a more high tech version? The Nod ring could be for you. Slip it on your finger, pick up your wand, and you suddenly have control over everything from your phone to your TV, simply by using gestures. No, it’s not magic, but it’ll certainly look a lot like it.The Nod ring is essentially a clever, wearable universal controller, which will interact with many mobile devices running Android or iOS, Windows or Mac computers, the Nest thermostat, your TV, and even connected lightbulbs. To make things work, you use gestures. For example, pointing at your TV will turn it on, twisting your hand will raise or lower the temperature on the Nest thermostat, and swipes will help you play Fruit Ninja.
It doesn’t stop there. It’ll work with a Swype-like keyboard, Philips Hue lights can be dimmed with a simple up or down motion, and for those times you don’t want to use gestures, the Nod has a small touch panel and a set of clickable buttons. These are shown to work with audio apps on your phone, so you can swipe through tracks or adjust the volume. The idea is very cool, but the video does raise some concerns over the ring’s accuracy, particularly when using it to type on the keyboard, but this could be fixed before release.
