Adjustment of a mixed reality display for inter-pupillary distance alignment
First Claim
1. A system for adjusting a near-eye, mixed reality display for alignment with an inter-pupillary distance (IPD) comprising:
- a near-eye, mixed reality display device including, for each of two eyes, a display optical system, each display optical system having an optical axis and being positioned to be seen through by a respective eye;
the display device including a respective movable support structure for supporting each display optical system;
at least one sensor for each display optical system attached to the display device, the sensor having a detection area at a position to capture data of the respective eye;
a memory for storing software and data including the captured data of each eye;
one or more processors having access to the memory for determining one or more position adjustment values for each display optical system based on the captured data and the position of the respective detection area for alignment with the IPD; and
a respective display adjustment mechanism attached to each display optical system and communicatively coupled to the one or more processors, each display adjustment mechanism adapted to independently move the respective display optical system by moving a respective movable support structure to adjust a position of the respective display optical system in accordance with the one or more position adjustment values.

Abstract
The technology provides for adjusting a see-through, near-eye, mixed reality display device for alignment with an inter-pupillary distance (IPD) of a user by different examples of display adjustment mechanisms. The see-through, near-eye, mixed reality system includes for each eye a display optical system having an optical axis. Each display optical system is positioned to be seen through by a respective eye, and is supported on a respective movable support structure. A display adjustment mechanism attached to the display device also connects with each movable support structure for moving the structure. A determination is automatically made as to whether the display device is aligned with an IPD of a user. If not aligned, one or more adjustment values for a position of at least one of the display optical systems is automatically determined. The display adjustment mechanism moves the at least one display optical system in accordance with the adjustment values.

10. In a near-eye, mixed reality system including, for each eye of a wearer, a display optical system, each display optical system having an optical axis and being positioned to be seen through by a respective eye, a method for aligning a near-eye, mixed reality display device with an inter-pupillary distance (IPD) for the wearer, the method comprising:
-
automatically determining whether the near-eye, mixed reality display is aligned with a wearer IPD in accordance with an alignment criteria; and responsive to the display device not being aligned with the wearer IPD in accordance with the alignment criteria, determining one or more adjustment values for at least one display optical system for satisfying the alignment criteria, and adjusting one or both display optical systems based on the one or more adjustment values, each display optical system supported by an independently movable support structure, by moving at least one independently movable support structure based on the one or more adjustment values. - View Dependent Claims (11, 12, 13, 14)

15. A system for adjusting a near-eye display system in any of three dimensions for alignment with an inter-pupillary distance of a user comprising:
-
a near-eye, mixed reality display device including for each eye; a display optical system, each display optical system having an optical axis and being positioned to be seen through by a respective eye; the display device including a respective independently movable support structure for supporting each display optical system, the respective independently movable support structure being capable of movement in three dimensions; at least one sensor for each display optical system attached to the display device, the sensor having a detection area at a position for capturing data of the respective eye; a memory for storing software and data including the captured data of each eye; one or more processors having access to the memory for determining one or more position adjustment values in any of three dimensions for each display optical system based on the captured data and the position of the respective detection area for alignment with the IPD; and at least one display adjustment mechanism attached to the display device and communicatively coupled to the one or more processors for moving at least one independently movable support structure in any of three dimensions under control of the one or more processors in accordance with the one or more position adjustment values. - View Dependent Claims (16, 17, 18, 19, 20)
