Abstract

Embodiments are disclosed herein that relate to aligning a near-eye display of a near-eye display device with an eye of a user. For example, one disclosed embodiment provides, on a near-eye display device, a method comprising receiving an image of an eye from a camera via a reverse display optical path, detecting a location of the eye in the image, and determining a relative position of the eye with regard to a target viewing position of the near-eye display. The method further comprises determining an adjustment to make to the near-eye display device to align the location of the eye with the target viewing position.

Claims

1. On a near-eye display device comprising a display and a display optical path that delivers images from the display to an eye of a user, a method of aligning a near-eye display with the eye of a user, the method comprising:

receiving from a camera an image of the eye along a reverse display optical path;

detecting a location of the eye in the image;

determining a relative position of the eye with regard to a target viewing position of the near-eye display; and

determining an adjustment to make to align the location of the eye with the target viewing position.

2. The method of claim 1, further comprising automatically performing the adjustment determined

3. The method of claim 1, further comprising outputting a recommendation to make the adjustment.

4. The method of claim 3, wherein outputting the recommendation comprises outputting one or more of an acoustic recommendation and a visual recommendation.

5. The method of claim 4, wherein outputting the visual recommendation comprises displaying an arrow that indicates a direction in which to adjust the near-eye display.

6. The method of claim 3, wherein the recommendation comprises one or more of a recommended vertical adjustment and a recommended horizontal adjustment.

7. The method of claim 3, wherein the recommendation directs a user to use to a different size near-eye display if an available range of adjustment is insufficient to make the adjustment.

8. The method of claim 3, wherein the outputting the recommendation comprises providing one or more of a haptic output and a tactile output.

9. The method of claim 1, wherein the adjustment is determined based upon a determined interpupillary distance of a user.

10. The method of claim 1, wherein the camera comprises an eye tracking system camera.

11. The method of claim 10, wherein the display optical path comprises a beam splitter, and wherein the beam splitter is configured to direct the image of the eye toward the camera.

12. On a computing device comprising a near-eye display for each eye of a user, a method of aligning the near-eye display to a first eye and a second eye of a user, the method comprising:

receiving from a first camera an image of the first eye via a reverse display optical path for a display for the first eye;

receiving from a second camera an image of the second eye via a reverse display optical path for a display of the second eye;

detecting a location of the first eye in the image of the first eye and a location of the second eye in the image of the second eye;

determining a relative position of the first eye to a first eye target viewing position of the near-eye display;

determining a relative position of the second eye to a second eye target viewing position; and

determining an adjustment to make to the near-eye display based upon one or more of the relative position of the first eye to the first eye target viewing position and the relative position of the second eye to the second eye target viewing position.

13. The method of claim 12, further comprising outputting a recommendation of the adjustment to make.

14. The method of claim 12, wherein the adjustment is determined based upon an interpupillary distance.

15. The method of claim 12, further comprising performing the adjustment automatically.

16. The method of claim 12, further comprising determining an absolute position of an adjustment mechanism, and outputting a recommendation to use a different sized device if an available range of adjustment is insufficient to make the adjustment.

17. On a computing device, a method of operating a near-eye display device, the method comprising:

receiving from a first camera an image of a first eye, the first camera configured to receive the image of the first eye via a reverse display optical path;

receiving from a second camera an image of a second eye, the second camera configured to receive the image of the second eye via a reverse display optical path;

detecting a location of the first eye in the image of the first eye and a location of the second eye in the image of the second eye;

determining an interpupillary distance of a user from the location of the first eye and the location of the second eye; and

outputting a recommendation of an adjustment to make to the near-eye display device to align the near-eye display device with the first eye and the second eye of the user.

18. The method of claim 17, wherein outputting the recommendation comprises outputting information regarding a recommended manual adjustment.

19. The method of claim 17, wherein the first camera and the second camera each are a part of an eye tracking system.

20. The method of claim 17, wherein the recommendation directs a user to use to a different size near-eye display device.
