“Imagine walking to a crosswalk and doing the “halt” hand motion in the direction of traffic. Your ring and your watch can tell by their orientation to each other that you have formed that gesture and so they send a “pedestrian waiting” message to the street light. The lights change for you and you cross. It will feel like magic. Or point at something in a vending machine and your watch and ring can detect which item you selected, charge your credit card, and send a code to release the item. To an observer it will seem that you pointed at an item and magic released it.”
