"OK Glass:" Find me directions
One of the most common features of Glass is being able to find directions by walking, public transit, or car.
Connecting to your smartphone's cellular connection and GPS but using its in-built compass, you can walk around almost anywhere and see from an aerial map view.
Tell Glass your destination and it will tell you how long it will take and offer step-by-step directions. If you spin around, Glass will show you on the map which direction you are facing — which is particularly handy when exiting subway stations.
