Abstract: According to various implementations, a method is performed at a first electronic device with a non-transitory memory and one or more processors. The method includes determining a reference location in a three-dimensional space based on a feature. The feature is generated by a second electronic device. The method includes obtaining, for the reference location, first reference coordinates in an augmented reality coordinate system of the first electronic device and second reference coordinates in an augmented reality coordinate system of the second electronic device. The method includes determining a coordinate transformation based on a function of the first reference coordinates and the second reference coordinates. The method includes synchronizing an augmented reality coordinate system of the first electronic device with an augmented reality coordinate system of the second electronic device using the coordinate transformation.

Abstract: In one implementation, a method, performed at a first electronic device with one or more processors, a display, and one or more input devices, includes obtaining, for a reference location in a three-dimensional space, first reference coordinates in an augmented reality coordinate system of the first electronic device. The method includes obtaining, for the reference location in the three-dimensional space, second reference coordinates based on transformation data received from a second electronic device. The method includes determining a coordinate transformation based on the first reference coordinates and the second reference coordinates. The method includes synchronizing the augmented reality coordinate system of the first electronic device with an augmented reality coordinate system of the second electronic device using the coordinate transformation.
