1. A head-mounted display (HMD) device comprising:

  • an at least partially see-through display configured to display an augmented reality image representing a virtual object, the virtual object having at least a first portion, a second portion, and an associated script for animating the virtual object;

    one or more location sensors from which the HMD device determines at least a location of the HMD device in a physical environment;

    a communication unit configured to receive peer location data from at least one peer HMD device in the physical environment, wherein the peer location data indicates a peer field of view of the at least one peer HMD device, the peer field of view comprising a range within which augmented reality images may be presented; and

    a processor configured to;

    based at least on the received peer location data, identify a display position at which the virtual object is to be displayed and viewed in the physical environment by the HMD device and the at least one peer HMD device;

    determine a shared focal point based on the display position, the location of the HMD device, and the peer location data;

    determine a first orientation of the first portion of the virtual object at the display position based on the shared focal point and focal point information of the script, the first orientation being common to the HMD device and the at least one peer HMD device;

    determine a second orientation of the second portion of the virtual object at the display position based on the focal point information and a device-specific focal point that corresponds to the location of the HMD device relative to the display position, the second orientation being specific to the location of the HMD device and differing from the at least one peer HMD device; and

    display and animate the augmented reality image of the virtual object at the display position with the first portion at the first orientation and the second portion at the second orientation on the at least partially see-through display of the HMD device according to the script.
