Selectively blurring a portion of an image based on a user's accommodation

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 method for displaying virtual content, comprising:
 determining an accommodation of a user's eyes;   scanning a plurality of light beams associated with one or more frames of image data, through a fiber scanning display, wherein a diameter of the light beam is no greater than 0.5 mm, such that the frames of image data appear in focus when viewed by the user; and   blurring, using blur software, one or more portions of the frame based at least in part on the determined accommodation of the user's eyes.   
     
     
         2 . The method of  claim 1 , further comprising modifying a diameter of the plurality of light beams such that the one or more light beams are perceived to be in focus by the user. 
     
     
         3 . The method of  claim 2 , wherein the diameter of light beams is no greater than 2 mm. 
     
     
         4 . The method of  claim 2 , wherein the diameter of light beams is no greater than 0.5 mm. 
     
     
         5 . The method of  claim 1 , further comprising duplicating a scanned light beam to create a plurality of exit pupils. 
     
     
         6 . The method of  claim 1 , further comprising multiplying scanned light beams to increase a size of an eye box. 
     
     
         7 . The method of  claim 1 , wherein the light beam is generated by a singlecore fiber. 
     
     
         8 . The method of  claim 5 , further comprising switching the plurality of exit pupils based at least in part on an eye position, such that the user's eyes receive a subset of the exit pupils. 
     
     
         9 . The method of  claim 5 , further comprising modifying a pitch of the plurality of the exit pupils to control how the light beams hit a pupil of the user's eyes. 
     
     
         10 . The method of  claim 1 , wherein the one or more frames of image data are delivered in a frame sequential manner.
