DRIVING LIGHT PATTERNS TO EXIT PUPILS FOR AUGMENTED OR VIRTUAL REALITY
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.
1 . A method for displaying virtual content to a user, the method comprising:
grouping a plurality of light projectors to form an exit pupil;
driving a first light pattern, through a first exit pupil, into a first portion of the user's pupil; and
driving a second light pattern, through a second exit pupil, into a second portion of the user's pupil, wherein the first light pattern and second light pattern corresponds to sub-images of an image to be presented to the user, and wherein the first light pattern is different than the second light pattern.
2 . The method of claim 1 , wherein the plurality of light projectors is arranged in a hexagonal lattice.
3 . The method of claim 1 , wherein the plurality of light projectors is arranged in a square lattice.
4 . The method of claim 1 , wherein the plurality of light projectors is arranged in a two-dimensional array.
5 . The method of claim 1 , wherein the plurality of light projectors is arranged in a three-dimensional array.
6 . The method of claim 1 , wherein the plurality of light projectors is arranged in a time-varying array.
7 . The method of claim 1 , wherein the first portion of the user's pupil only receives light from the first exit pupil, and wherein the second portion of the user's pupil only receives light from the second exit pupil.
8 . The method of claim 1 , further comprising creating a discretized aggregate wavefront.
9 . The method of claim 1 , wherein the light patterns correspond to one or more frames of image data.
10 . The method of claim 1 , wherein a perceived focus of the first driven light pattern is different from the perceived focus of the second driven light pattern.
