Using blurring to create multiple depth planes 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 comprising;
 an accommodation tracking module to determine an accommodation of a user's eyes;   a fiber scanning display to scan a plurality of light beams associated with one or more frames of image data, wherein a light beam of the plurality of light beams is movable;   a blur software to render a simulated dioptric blur in the one or more frames of image data based at least in part on the determined accommodation of the user's eyes.   
     
     
         2 . The system of  claim 1 , wherein the fiber scanning display modifies a diameter of the plurality of light beams such that the plurality of light beams is always perceived to be in focus by the user. 
     
     
         3 . The system of  claim 2 , wherein the diameter of light beams is no greater than 2 mm. 
     
     
         4 . The system of  claim 2 , wherein the diameter of light beams is no greater than 0.5 mm. 
     
     
         5 . The system of  claim 1 , wherein a scanned light beam is duplicated to create a plurality of exit pupils. 
     
     
         6 . The system of  claim 1 , wherein the scanned light beam is duplicated to create a larger eye box. 
     
     
         7 . The system of  claim 5 , wherein the exit pupils are switchable based at least in part on an eye position, such that the user's eyes receives a subset of the exit pupils. 
     
     
         8 . The system of  claim 1 , wherein the one or more frames of image data are scanned in a time-sequential manner. 
     
     
         9 . The system of  claim 5 , wherein the plurality of light beams appear to be in focus when perceived by the user. 
     
     
         10 . The system of  claim 1 , wherein a pitch of the plurality of exit pupils is altered to control how the light beams hit a pupil of the user's eyes.
