Abstract
Described herein is a system and method for creating a shared coordinate space in an augmented reality session between two devices with disjoint relative coordinate spaces. With AR tracking initiated, each device has its own relative coordinate space. A spatial alignment image can be recognized by a device joining an AR session which records its location (e.g., six degrees of position). The joining device can utilize an obtained location of an inviting device at or about the time the spatial alignment image was recognized, and, a spatial origin of the inviting device, to calculate an offset between the joining device and the inviting device, establishing a shared coordinate space between the joining device and the inviting device.
