Abstract: The present disclosure relates to providing a multi-user computer generated reality (“CGR”) session. In some embodiments, a first electronic device displays a CGR environment, wherein the CGR environment is responsive to input from the first electronic device and a second electronic device, wherein the second device is external to the first device. While displaying the CGR environment, the device obtains a first scene graph from a process executing on the first device, wherein the first scene graph includes information for rendering a first entity, and obtains a second scene graph from a process executing on the second device, wherein the second scene graph includes information for rendering a second entity. The first electronic device updates the displayed CGR environment based on the first scene graph and the second scene graph, wherein the displayed CGR environment includes a visual representation of the first and a visual representation of the second entity.

Abstract: Various implementations disclosed herein include devices, systems, and methods that provide authority transfer of a virtual object in a shared CGR environment. In some implementations, at a first electronic device associated with a first owner having authority to transmit state updates of a virtual object, a state update is transmitted to one or more peers participating in the shared CGR environment associated with the current state of the virtual object by the first electronic device. In some implementations, a handoff message is transmitted to indicate that ownership of the virtual object is being handed off. Then, an acquisition message transmitted by a second electronic device associated with a second owner indicates ownership acquisition of the virtual object by the second owner. The first electronic device accepts state updates of the virtual object transmitted from the second owner based on receiving the acquisition message.
