Curved waveguides for augmented or virtual reality

Abstract

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image-generating source to provide one or more frames of image data in a time-sequential manner, a light modulator configured to transmit light associated with the one or more frames of image data, a substrate to direct image information to a user's eye, wherein the substrate houses a plurality of reflectors, a first reflector of the plurality of reflectors to reflect transmitted light associated with a first frame of image data at a first angle to the user's eye, and a second reflector to reflect transmitted light associated with a second frame of the image data at a second angle to the user's eye.

What is claimed is: 
     
         1 . A system for displaying virtual content to a user, the system comprising:
 a light projector to project light associated with one or more frames of image data, wherein the light projector is a fiber scanning display;   a waveguide assembly to variably deflect light to a user's eye, wherein the waveguide is curved concavely toward the eye.   
     
     
         2 . The system of  claim 1 , wherein the curved waveguide expands a field of view. 
     
     
         3 . The system of  claim 1 , wherein the curved waveguide efficiently directs light to the user's eye. 
     
     
         4 . The system of  claim 1 , wherein the curved waveguide comprises a time-varying grating, thereby creating an axis for scanning the light for the fiber scanning display. 
     
     
         5 . The system of  claim 1 , wherein the waveguide assembly comprises one or more waveguides. 
     
     
         6 . The system of  claim 5 , wherein the one or more waveguides comprises a single waveguide. 
     
     
         7 . The system of  claim 5 , wherein the one or more waveguides comprises a plurality of waveguides. 
     
     
         8 . The system of  claim 1 , further comprises an accommodation tracking module to determine an accommodation of the user's eyes. 
     
     
         9 . The system of  claim 8 , wherein the waveguide assembly variably deflects the light based at least in part on the determined accommodation. 
     
     
         10 . The system of  claim 1  implemented as a method.
