Abstract

A near-eye display system includes one or more non-planar display panels and a lenslet array to display a near-eye lightfield frame. The near-eye display system further includes a rendering component to render, based on a stereoscopic focus volume associated with a set of display geometry data of the one-or more non-planar display panels, the array of elemental images in the near-eye lightfield frame such that objects within the stereoscopic focus volume are perceived to be in focus by the user's eye. A method of operation of the near-eye display system includes receiving display geometry data for one or more non-planar display panels of the near-eye display system and rendering, based on a stereoscopic focus volume, an array of elemental images at a position within a near-eye lightfield frame such that the non-planar display panels presents objects within the stereoscopic focus volume to be in focus.

First claim

What is claimed is:

1 . In a near-eye display system, a method comprising:
receiving display geometry data for one or more non-planar display panels of the near-eye display system; rendering, based on a stereoscopic focus volume associated with the display geometry data of the one-or more non-planar display panels, an array of elemental images at a position within a near-eye lightfield frame, wherein the one or more non-planar display panels presents objects within the stereoscopic focus volume to be in focus; and communicating the near-eye lightfield frame for display at the one or more non-planar display panels of the near-eye display system.

2 . The method of claim 1 , wherein receiving display geometry data comprises:
receiving data that indicates the one or more non-planar display panels comprises a plurality of display panel segments.

3 . The method of claim 2 , wherein determining the stereoscopic focus volume further comprises:
determining a focus volume for each of the plurality of display panel segments, wherein each of the plurality of display panel segments presents objects within its corresponding focus volume to be in focus; and determining the stereoscopic focus volume based at least in part on an overlap between the focus volume for each of the plurality of display panel segments.

4 . The method of claim 1 , wherein receiving display geometry data comprises:
receiving data that indicates curvature geometry of the one or more non-planar display panels.

5 . The method of claim 1 , wherein receiving display geometry data comprises:
receiving data that indicates a set of display border data representing positions of display borders of the one or more non-planar display panels.

6 . The method of claim 5 , further comprising:
determining, using an eye tracking component of the near-eye display system, a pose of a user's eye; and modifying, based on the pose of the user's eye and the set of display border data, the rendering of the array of elemental images to prevent perception of the display borders of the one or more non-planar display panels by the user's eye.

7 . The method of claim 6 , wherein determining the pose of the user's eye comprises:
capturing imagery of the user's eye using an imaging camera disposed between the one or more non-planar display panels and the user's eye.

8 . The method of claim 1 , further comprising:
rotating a position of a virtual plane within the stereoscopic focus volume by shifting display position of the array of elemental images.

9 . The method of claim 1 , further comprising:
rotating a position of a virtual plane within the stereoscopic focus volume by changing a fold angle between two or more non-planar display panels.

10 . A near-eye display system, comprising:
one or more non-planar display panels to display a near-eye lightfield frame comprising an array of elemental images; a rendering component to render, based on a stereoscopic focus volume associated with a set of display geometry data of the one-or more non-planar display panels, the array of elemental images in the near-eye lightfield frame such that objects within the stereoscopic focus volume are perceived to be in focus by the user's eye; and a lenslet array to present the near-eye lightfield frame to a user's eye.

11 . The near-eye display system of claim 10 , wherein the processor is further to determine the stereoscopic focus volume by:
receiving data that indicates the one or more non-planar display panels comprises a plurality of display panel segments; determining a focus volume for each of the plurality of display panel segments, wherein each of the plurality of display panel segments presents objects within its corresponding focus volume to be in focus; and determining the stereoscopic focus volume based at least in part on an overlap between the focus volume for each of the plurality of display panel segments.

12 . The near-eye display system of claim 10 , wherein the processor is further to determine the stereoscopic focus volume by:
receiving data that indicates a set of display border data representing positions of display borders of the one or more non-planar display panels; determining, using an eye tracking component of the near-eye display system, a pose of a user's eye; and modifying, based on the pose of the user's eye and the set of display border data, the rendering of the array of elemental images to prevent perception of the display borders of the one or more non-planar display panels by the user's eye.

13 . The near-eye display system of claim 10 , further comprising:
an eye tracking component to track a pose of the user's eye, wherein the eye tracking component comprises a set of one or more infrared (IR) illuminators to project light onto the user's eye and an imaging camera disposed between the lenslet array and the one or more non-planar display panels and oriented towards the user's eye through the lenslet array.

14 . The near-eye display system of claim 10 , wherein the one or more non-planar display panels comprises:
a single continuous display panel including different lateral portions having differing degrees of curvature.

15 . The near-eye display system of claim 10 , wherein the one or more non-planar display panels comprises:
a plurality of flat panel displays positioned in a non-planar orientation relative to each other.

16 . A rendering system, comprising:
at least one processor; an input to receive data indicating a set of display geometry data for one or more non-planar display panels of a near-eye display system; and a storage component to store a set of executable instructions, the set of executable instructions configured to manipulate the at least one processor to render, based on a stereoscopic focus volume associated with the set of display geometry data of the one-or more non-planar display panels, an array of elemental images at a position within a near-eye lightfield frame, wherein the one or more non-planar display panels presents objects within the stereoscopic focus volume to be in focus.

17 . The rendering system of claim 16 , wherein the set of executable instructions are further configured to determine the stereoscopic focus volume by:
receiving data that indicates a set of display border data representing positions of display borders of the one or more non-planar display panels; determining, using an eye tracking component of the near-eye display system, a pose of a user's eye; and modifying, based on the pose of the user's eye and the set of display border data, the rendering of the array of elemental images to prevent perception of the display borders of the one or more non-planar display panels by the user's eye.

18 . The rendering system of claim 16 , wherein the set of display geometry data comprises data that indicates the one or more non-planar display panels comprises a plurality of display panel segments.

19 . The rendering system of claim 18 , wherein the set of executable instructions are further configured to determine the stereoscopic focus volume by:
determining a focus volume for each of the plurality of display panel segments, wherein each of the plurality of display panel segments presents objects within its corresponding focus volume to be in focus; and determining the stereoscopic focus volume based at least in part on an overlap between the focus volume for each of the plurality of display panel segments.
