Determining user accommodation to display an image through a waveguide assembly

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, comprising:
 an image-generating source to provide one or more frames of image data in a time-sequential manner;   a light generator to provide light associated with the one or more frames of image data;   an accommodation tracking module to track an accommodation of the user's eye; and   a waveguide assembly to vary a focus of the light associated with the one or more frames of image data, wherein different frames of image data are focused differently based at least in part on the tracked accommodation.   
     
     
         2 . The system of  claim 1 , where the waveguide assembly comprises a plurality of waveguides, and wherein the focus of a first frame of image data transmitted from a first waveguide of the plurality of waveguides is different from the focus of a second frame of image data transmitted from a second waveguide of the plurality of waveguides. 
     
     
         3 . The system of  claim 2  wherein the first frame is a first layer of a 3D scene, and a second frame is a second layer of the 3D scene. 
     
     
         4 . The system of  claim 2 , further comprising a blurring module to blur a portion of the one or more frames of image data in a manner such that the portion is out of focus when viewed by the user. 
     
     
         5 . The system of  claim 2 , wherein a waveguide of the waveguide assembly is configured to modify the provided light such that it is focused on a particular depth plane. 
     
     
         6 . The system of  claim 2 , wherein a first waveguide of the waveguide assembly focuses light on a first depth plane, and a second waveguide of the waveguide assembly focuses light on a second depth plane, wherein the first depth plane is different from the second depth plane. 
     
     
         7 . The system of  claim 1 , further comprising selecting a waveguide of the waveguide assembly based at least in part on the tracked accommodation. 
     
     
         8 . The system of  claim 2 , wherein the waveguide of the waveguide assembly is electro-active. 
     
     
         9 . The system of  claim 1 , wherein one or more waveguides of the waveguide assembly is switched off. 
     
     
         10 . The system of  claim 1 , wherein the light generator is a scanning fiber display.
