Meet the TurnPoint Glove: a Bluetooth enabled wearable device that uses a LED interface to provide you with GPS directions on the road. It has 18 bright LEDs that you can easily see in sunlight. It uses animated patterns for turn-by-turn directions. When your thumb touches your index finger, you will be able to see the distance and direction to the next turn.
TurnPoint connects to an app on your smartphone to get turn by turn directions. It is expected to be compatible with iOS devices at first. You can find out more about this project on Kickstarter.
