    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.

    摘要： Methods and systems are disclosed for presenting virtual objects on a limited number of depth planes using, e.g., an augmented reality display system. A farthest one of the depth planes is within a mismatch tolerance of optical infinity. The display system may switch the depth plane on which content is actively displayed so that the content is displayed on the depth plane on which a user is fixating. The impact of errors in fixation tracking is addressed using partially overlapping depth planes. A fixation depth is determined and the display system determines whether to adjust selection of a selected depth plane at which a virtual object is presented. The determination may be based on whether the fixation depth falls within a depth overlap region of adjacent depth planes. The display system may switch the active depth plane depending upon whether the fixation depth falls outside the overlap region.

    摘要： Various methods and apparatus are described herein for enabling one or more users to interface with virtual or augmented reality environments. An example system includes a computing network having computer servers interconnected through high bandwidth interfaces to gateways for processing data and/or for enabling communication of data between the servers and one or more local user interface devices. The servers include memory, processing circuitry, and software for designing and/or controlling virtual worlds, as well as for storing and processing user data and data provided by other components of the system. One or more virtual worlds may be presented to a user through a user device for the user to experience and interact. A large number of users may each use a device to simultaneously interface with one or more digital worlds by using the device to observe and interact with each other and with objects produced within the digital worlds.
