DISPLAYING AUGMENTED REALITY OR VIRTUAL REALITY THROUGH A SUBSTRATE COUPLED TO THE USER'S EYE
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, comprising:
providing one or more frames of image data to be presented to a user;
projecting light associated with the one or more frames of image data; and
receiving, through a partially hemispherical substrate coupled to the user's pupil, the projected light and selectively filtering out the light beams to the user's pupil.
2 . The method of claim 1 , wherein the light is filtered through a notch filter.
3 . The method of claim 2 , wherein the notch filter substantially blocks wavelengths at approximately 450 nm (peak blue) and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum.
4 . The method of claim 2 , wherein the notch filter substantially blocks wavelengths at approximately 530 nm (green) and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum.
5 . The method of claim 2 , wherein the notch filter substantially blocks wavelengths at approximately 650 nm and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum.
6 . The method of claim 2 , wherein the notch filter comprises a plurality of layers of dielectric materials carried by the substrate.
7 . The method of claim 2 , wherein the filter has a pinhole opening of less than 1.5 mm diameter.
8 . The method of claim 7 , wherein the pinhole opening allows light beams of a plurality of wavelengths to pass through.
9 . The method of claim 7 , wherein a size of the pinhole is varied based at least in part on a desired depth of focus of the display.
10 . The method of claim 1 , wherein the partially hemispherical substrate is a contact lens.
