In the patent data, Apple notes that while delivering an augmented reality experience to a user in an environment, an augmented reality coordinate system is used to map the environment, track the user’s location in the environment, and present virtual objects in the environment. However, when multiple users are present in the environment, each user maintains their own augmented reality coordinate system, which complicates the sharing of the augmented reality experience among multiple users. Apple wants to facilitate this process.
Here is the summary of the patent: “an implementation, a method, performed on a first electronic device with one or more processors, a monitor and one or more input devices, includes obtaining, for a reference location in a three-dimensional space, first reference coordinates in an enlarged reality-coordinate system for the first electronic device The method includes obtaining, for the reference location in the three-dimensional space, other 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. “
As for Apple Glasses, such a device will arrive next year or 2022, depending on what reputation you believe. It will be a head mounted monitor. Or may have a design like “normal”
