（3） AR Navigation
Navigation is, perhaps, the most natural fit between AR and useful technology. Simply put, when you’re going somewhere, you need to know both where you are and where you’re going. Augmented Reality will show you how to reach the destination vividly. In July 2016, we implemented AR navigation on Alibaba Make Festival, which will direct the users from the subway station to the entrance of shanghai Expo Park. Through outdoor/indoor location and IMU sensors, the system gets the users’ precise position and direction. After that, the system will put Tao Doll on the mobile screen show you the way to the destination. The interaction is very simple, even the elementary school student can use it easily.
