Abstract
A relative position of an interpupillary midpoint between a first eye and a second eye of a user with respect to an image plane of an image-replicating display is determined. An image to be displayed is generated or retrieved based on the relative position of the interpupillary midpoint with respect to the image plane. This image corresponds to a perspective projection having a view origin at the interpupillary midpoint and aligned with an optical axis of the image-replicating display. The image is displayed via the image-replicating display, which is configured to emit light rays forming a spatially-invariant angular light field from each of a plurality of positions on an exit aperture of the image-replicating display.
Claims17
A system comprising:
- a tracker;
- an image-replicating display configured to emit light rays forming a spatially-invariant angular light field from each of a plurality of positions on an exit aperture of the image-replicating display;
- and
- at least one processor configured to:
- determine a relative position of an interpupillary midpoint between a first eye and a second eye of a user with respect to an image plane of the image-replicating display, using the tracker;
- generate or retrieve an image to be displayed based on the relative position of the interpupillary midpoint with respect to the image plane, wherein the image corresponds to a perspective projection having a view origin at the interpupillary midpoint and aligned with an optical axis of the image-replicating display;
- and
- display the image via the image-replicating display.
A method comprising:
- determining a relative position of an interpupillary midpoint between a first eye and a second eye of a user with respect to an image plane of an image-replicating display, using a tracker;
- generating or retrieving an image to be displayed based on the relative position of the interpupillary midpoint with respect to the image plane, wherein the image corresponds to a perspective projection having a view origin at the interpupillary midpoint and aligned with an optical axis of the image-replicating display;
- and
- displaying the image via the image-replicating display, wherein the image-replicating display is configured to emit light rays forming a spatially-invariant angular light field from each of a plurality of positions on an exit aperture of the image-replicating display.
