Modulating light intensity to enable viewing of dark virtual objects

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, comprising:
 a camera system to capture a view of a real environment;   an optical see-through system that displays one or more virtual objects superimposed over the view of the real environment, wherein the captured view is used to render the one or more virtual objects presented to the user; and   a light intensity module to modulate a light intensity of the view of the real environment, based at least on a correlation between one or more real objects, and the one or more virtual objects, such that a dark virtual object is visible in contrast with the one or more real objects.   
     
     
         2 . The system of  claim 1 , wherein the captured view is used to generate a halo around one or more virtual objects, wherein the halo fades across space. 
     
     
         3 . The system of  claim 2 , further comprising a light attenuator, wherein the light attenuator balances a light intensity of the halo across the visual field of the user. 
     
     
         4 . The system of  claim 2 , wherein the halo is rendered spatially proximate to the one or more virtual objects. 
     
     
         5 . The system of  claim 4 , wherein the rendered halo is brighter than the rendered one or more virtual objects. 
     
     
         6 . The system of  claim 1 , wherein the one or more virtual objects is darker than a threshold value of darkness. 
     
     
         7 . The system of  claim 2 , wherein the halo is rendered based at least in part on light from an outside environment. 
     
     
         8 . The system of  claim 2 , wherein the halo is rendered in a separate focal plane from the one or more virtual objects. 
     
     
         9 . The system of  claim 2 , wherein the halo is rendered in a same focal plane as the one or more virtual objects. 
     
     
         10 . The system of  claim 1  implemented as a method.
