Aligning inter-pupillary distance in a near-eye display system
First Claim
1. A method for automatically aligning a near-eye, mixed reality display device with an inter-pupillary distance (IPD) for a wearer, comprising:
- automatically determining whether the near-eye, mixed reality display device, including a respective display optical system for each eye of the wearer which is positioned to be seen through by the respective eye, is aligned with a wearer IPD in accordance with an alignment criteria based on determining whether each optical axis of the respective display optical system positioned in the display device satisfies the alignment criteria for alignment with a respective pupil of the wearer; and
responsive to the display device not being aligned with the wearer IPD in accordance with the alignment criteria, automatically adjusting a position of one or both of the display optical systems within the display device for bringing the display device into alignment with the wearer IPD, wherein the automatically adjusting comprisesdetermining at least one adjustment value for a respective display adjustment mechanism based on a mapping criteria of the at least one sensor for each display optical system not satisfying the alignment criteria; and
moving the respective display optical system based on the at least one adjustment value.

Abstract
The technology provides for automatic alignment of a see-through near-eye, mixed reality device with an inter-pupillary distance (IPD). A determination is made as to whether a see-through, near-eye, mixed reality display device is aligned with an IPD of a user. If the display device is not aligned with the IPD, the display device is automatically adjusted. In some examples, the alignment determination is based on determinations of whether an optical axis of each display optical system positioned to be seen through by a respective eye is aligned with a pupil of the respective eye in accordance with an alignment criteria. The pupil alignment may be determined based on an arrangement of gaze detection elements for each display optical system including at least one sensor for capturing data of the respective eye and the captured data. The captured data may be image data, image and glint data, and glint data only.

8. A system for automatically aligning a near-eye, mixed reality display with an inter-pupillary distance (IPD) of a user comprising:
-
a near-eye, mixed reality display device having a support structure including independently movable support structures, and having attached to a respective independently movable support structure a respective display optical system for each eye positioned to be seen through by the respective eye, each display optical system having an optical axis; a display adjustment mechanism attached to at least one independently movable support structure for automatically adjusting a position of the respective display optical system; a respective arrangement of gaze detection elements positioned with respect to each display optical system on the respective independently movable support structure for forming a spatial relationship between the gaze detection elements and the respective eye; each respective arrangement including at least one respective sensor having a detection area for capturing data of the respective eye of the respective display optical system; a memory for storing software and data including the captured data of each eye; and one or more processors having access to the memory and being communicatively coupled to the display adjustment mechanism for automatically re-positioning at least one display optical system within the display device for alignment of the optical axes of the display optical systems with the inter-pupillary distance based on the captured data and the arrangement of gaze detection elements. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for automatically aligning a near-eye, mixed reality display device with an inter-pupillary distance (IPD) of a wearer, comprising:
-
automatically determining whether the near-eye, mixed reality display device, including a respective display optical system for each eye of the wearer which is positioned to be seen through by the respective eye, is aligned with a wearer IPD in accordance with an alignment criteria based on determining whether each optical axis of the respective display optical system positioned in the display device satisfies the alignment criteria for alignment with a respective pupil of the wearer; and responsive to the display device not being aligned with the wearer IPD in accordance with the alignment criteria, automatically adjusting a position of one or both of the display optical systems, each display optical system supported by an independently movable support structure, within the display device for bringing the display device into alignment with the wearer IPD; detecting a change indicating an alignment with the wearer IPD no longer satisfies the alignment criteria; and automatically re-adjusting the one or both of the display optical systems positioned to be seen through by a respective eye for satisfying the alignment criteria. - View Dependent Claims (15, 16, 17, 18, 19)
