According to Investor's Business Daily, "GPS jewelry may one day help wearers find their way in unfamiliar surroundings. The BBC reported that an inventor has developed GPS-linked rings, one for each hand. The rings are wirelessly connected to a GPS device wearers use to input their destination. If wearers head the wrong way, the rings vibrate to steer them left or right to get back on course." The gadget works by vibrating your left hand when it's time to turn left, and vibrating your right hand when it's time to turn right.
