            accessing first pose data from a first Visual Inertial Odometry (VIO) system of a first device; 
                accessing, using a camera of a first device, an image of a machine-readable code that is displayed on a display of a second device, the machine-readable code being encoded by the second device with second pose data from a second VIO system of the second device; 
                decoding, at the first device, the second pose data from the machine-readable code; and 
                determining, at the first device, a relative pose between the first device and the second device based on the first pose data and the second pose data.
