Modifying a focus of virtual images through a variable focus element
First Claim
1. A system for displaying virtual content to a user, comprising:
- a light source to multiplex one or more light patterns associated with one or more frames of image data in a time-sequential manner;
a waveguide to receive the one or more light patterns at a first focus level;
a variable focus element (VFE) coupled to and located on a first side external to the waveguide and defining a first plurality of focus levels to place at least some of the light patterns at a second focus level of the plurality of focus levels; and
a second VFE that is located on a second side external to the waveguide and defines a second plurality of focus levels to adjust a focus of light from an outside world such that the user'"'"'s view of the outside world is substantially undistorted as the second VFE varies the focus of the light from the outside world.

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.
