Sci-fi movies set in the future often show characters controlling their environment with little more than a wave of the hand. The future is now here, and devices like Nod are making it happen. Nod, designed by Nod Labs, is a simple control that fits over your finger and lets you operate everything in your home from the lights to the thermostat to video games.
Another brilliant step forward in the field of interaction technology, the Nod essentially makes your body the input device. Rather than using buttons or a touchscreen to control, say, a slideshow presentation at work or school, you can just wiggle your thumb to move from one slide to the next. This on its own may not seem like a big deal, but Nod can be work everywhere, at all times, to control all kinds of things in your life. It’s even waterproof, so you can wear it in the shower or pool without worrying about losing it.
Using 32,000 DPI resolution, Nod can follow your commands to within half a millimeter of accuracy. It runs on Bluetooth’s Low Energy technology, giving it a battery life of approximately one full day. When it’s ready to charge, you pop it into a ring box that’s connected to a wall socket or USB outlet.
Nod’s open source programming interface will let programmers develop the device’s functionality and improve the way it interacts with its surroundings. It will eventually be compatible with Internet of Things so that nearly every electronic device in your home can be controlled with a single device that works as though it’s a part of your body.
