METHOD AND SYSTEM FOR UPDATING A VIRTUAL WORLD

摘要

A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

1. A method for updating a virtual world, comprising:
receiving first input from a first device of a first user, the first input corresponding to a physical environment of the first user; updating a virtual world model based on the received first input, the virtual world model corresponding to the physical environment of the first user; and transmitting first updated information corresponding to a first portion of the virtual world model to a second user, wherein the first updated information is configured to indicate whether any portion of the first updated information needs to be displayed to the second user.
