Walk around the city without looking as though you are a tourist, thanks to this GPS-enabled ring. Gail Knight from Britian has successfully developed a system made of GPS-enabled vibrating rings, where you wear one on each finger. The vibration will nudge you towards the right direction – for example, the ring on your right hand will buzz if you’re supposed to turn right and vice versa. Should you have taken the wrong turn, both rings will buzz. A pager-szied device kept in your pocket will retrieve those signals as you just have to enter a British postcode within. I only hope that the refresh rate will be fast enough to get your bearings lest you start getting double buzzes all the time.
