Remote controls are so old fashioned. Say hello to the Nod ring, which lets you control your devices with the swipe of the hand or the flick of the finger. With the Nod ring, you can type out a text message or control lights in a room. The Nod ring even connects to certain video game consoles, allowing you to play games with your hand.
Pre-order a Nod ring for $149. The company says shipments will begin this fall.
