Problems solved by technology

In the case of a head-mounted mixed reality display, if the optical axis of each optical system is not aligned with the corresponding eye, it may be difficult for the user to properly fuse three-dimensional (3D) content, or may be affected by the user's natural visual system. Muscle-like eyestrain or headaches
For binocular viewing devices like binoculars and binoculars, the user manually adjusts the position of each optical system in the eyepiece to obtain a clear binocular view through trial and error, which may take several minutes

Embodiment Construction

[0052] Interpupillary distance (IPD) generally refers to the horizontal distance between a user's pupils. IPDs may also include vertical or height dimensions. Additionally, many people have IPD that is asymmetrical relative to their nose. For example, the left eye is closer to the nose than the right eye.

[0053] The see-through, near-eye mixed reality display includes display optics for each eye with an optical axis positioned to be see-through by the respective eye. The display device is aligned with the user's IPD (asymmetric or symmetric) when the optical axis of each display optical system is aligned with the corresponding pupil. If each pupil is not aligned with the optical axis within a criterion, the corresponding display optics are adjusted via the display adjustment mechanism until the alignment satisfies a criterion. An example of a criterion is a distance, eg 1 mm. When the pupils are satisfactorily aligned with the optical axis, the distance between the optic...

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.

Description

technical field [0001] The present invention relates to mixed reality displays. Background technique [0002] Head-mounted displays and binoculars are examples of binocular viewing systems in which there are optical systems for each of the user's eyes to view the scene. There is an interpupillary distance between the pupils of the two eyes, estimates of which show that the distance varies between about 25 and 30 mm in adults. In the case of a head-mounted mixed reality display, if the optical axis of each optical system is not aligned with the corresponding eye, it may be difficult for the user to properly fuse three-dimensional (3D) content, or may be affected by the user's natural visual system. Muscles like tired eyes or headaches. For binocular viewing devices like binoculars and binoculars, the user manually adjusts the position of each optical system in the eyepieces by trial and error to obtain a clear binocular view, which may take several minutes. Contents of th...
