METHOD AND SYSTEM FOR RETRIEVING DATA IN RESPONSE TO USER INPUT
First Claim
1. A method of retrieving data, comprising:
- receiving a user input;
sending a request to a cloud server based on the determined user input;
receiving data from a knowledge base connected to the cloud server based on the request; and
displaying virtual content at the user device based on the received data.

Abstract
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.
