Modulating a depth of focus of a plurality of pixels displayed to a user

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:
 a light projection system to project light associated with one or more frames of image data to a user's eyes, the light project system configured to project light corresponding to a plurality of pixels associated with the image data; and   a processor to modulate a depth of focus of the plurality of pixels displayed to the user.   
     
     
         2 . The system of  claim 1 , wherein the depth of focus is modulated spatially. 
     
     
         3 . The system of  claim 1 , wherein the depth of focus is modulated over time. 
     
     
         4 . The system of  claim 1 , further comprising an image-generating source to provide the one or more frames of image data in a time-sequential manner. 
     
     
         5 . The system of  claim 1 , wherein the depth of focus is modulated on a frame-to-frame basis. 
     
     
         6 . The system of  claim 1 , wherein the light projection system comprises a plurality of optical fiber cores, and wherein the depth of focus is modulated across the plurality of optical fiber cores such that a portion of the optical fiber cores is associated with a first depth of focus, and another portion of the optical fiber cores is associated with a second depth of focus, wherein the first depth of focus is different from the second depth of focus. 
     
     
         7 . The system of  claim 1 , wherein a first display object of a particular frame is displayed through a first depth of focus, and a second display object of the particular frame is displayed through a second depth of focus, wherein the first depth of focus is different from the second depth of focus. 
     
     
         8 . The system of  claim 1 , wherein a first pixel of a particular frame is associated with a first depth of focus, and a second pixel of the particular frame is associated with a second depth of focus, wherein the first depth of focus is different from the second depth of focus. 
     
     
         9 . The system of  claim 1 , further comprising an accommodation tracking module to determine an accommodation of the user's eyes, wherein the depth of focus is modulated based at least in part on the determined accommodation. 
     
     
         10 . The system of  claim 9 , wherein a pattern of light generation associated with the light generation system is dynamically slaved to the determined accommodation. 
     
     
         11 . The system of  claim 10 , wherein the pattern is scanning pattern of a plurality of optical fiber cores. 
     
     
         12 . The system of  claim 1 , further comprising a blurring module to blur one or more portions of the image data, wherein the blurring is created to smooth a transition between a first scan pattern and a second scan pattern or a first resolution scan pitch to a second resolution scan pitch.
