Abstract
A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.
Claims20
A method for displaying virtual content to a user, comprising:
- propagating, using a plurality of light guiding structures, coherent light associated with one or more frames of image data;
- producing, using the plurality of light guiding structures, an aggregate wavefront;
- inducing, using a phase modulator coupled to one or more light guiding structures of the plurality of light guiding structures, one or more phase delays in projected light that is projected by the one or more light guiding structures;
- controlling, using a processor, the phase modulator in a manner such that the aggregate wavefront produced by the plurality of light guiding structures is varied between a planar wavefront and a plurality of curved wavefronts with respective curvatures that correspond to a plurality of focal distances for the virtual content;
- and
- presenting, using a waveguide assembly that comprises at least one weak lens, the image data at the plurality of focal distances to at least one eye of the user based at least in part upon the aggregate wavefront and the one or more phase delays.
