1. A method comprising: receiving a destination within a particular site at an augmented reality device, the augmented reality device comprising a plurality of cameras with at least a first camera imaging a field of view in front of the augmented reality device, a second camera imaging a field of view about a right side of the augmented reality device, and a third camera imaging a field of view about a left side of the augmented reality device; scanning a plurality of reference points outside a field of view of the first camera with one of the second and third cameras of the augmented reality device; detecting congestion along a plurality of paths to the destination based on communications from other augmented reality devices operating in the particular site; selecting a particular path from the plurality of paths to the destination based on said scanning of the plurality of reference points and said detecting congestion; layering over a real-world view presented by the augmented reality device, navigational information directing movement along the particular path to the destination; updating direction and orientation of said navigational information based in part on (i) size and offset positioning of one or more of said plurality of reference points in the field of view of at least one of the first, second, and third cameras and (ii) which of the first, second, and third cameras scan the one or more reference points; layering over the real-world view while at the destination, an action for a user to execute on a particular item at the destination, wherein said action comprises one of restocking or retrieving the particular item; tracking user retrieval of the particular item from the destination through one or more of the first, second, and third cameras of the augmented reality device; and decrementing remaining inventory of the particular item by one unit in response to tracking user retrieval of one unit of the particular item with one or more of the first, second, and third cameras, and by two units in response to tracking user retrieval of two units of the particular item with one or more of the first, second, and third cameras.
