Abstract: Embodiments are disclosed for a see-through head-mounted display system. In one embodiment, the see-through head-mounted display system comprises a freeform prism (316), an illumination prism (308), and a display device (306) configured to emit display light through the freeform prism and the illumination prism to an eye (302) of a user. The see-through head-mounted display system also comprises an imaging device (330), the imaging device configured to receive gaze-detection light reflected from the eye and directed through the freeform prism and the illumination prism.

Abstract: A system and method are disclosed for detecting angular displacement of a display element (104) relative to a reference position on a head mounted display device for presenting a mixed reality or virtual reality experience. Once the displacement is detected, it may be corrected for to maintain the proper binocular disparity of virtual images displayed to the left and right display elements of the head mounted display device. In one example, the detection system uses an optical assembly including collimated LEDs (130) and a camera (160) which together are insensitive to linear displacement. Such a system provides a true measure of angular displacement of one or both display elements on the head mounted display device in the presence of an interpupillary adjustment mechanism (126).
Abstract translation: 公开了一种用于检测显示元件（104）相对于头戴式显示装置上的参考位置的角位移的系统和方法，用于呈现混合现实或虚拟现实体验。 一旦检测到位移，可以对其进行修正，以保持显示在头戴式显示装置的左右显示元件上的虚拟图像的正确双目视差。 在一个示例中，检测系统使用包括准直的LED（130）和相机（160）的光学组件，其一起对线性位移不敏感。 这种系统在存在瞳孔内调节机构（126）的情况下提供头戴式显示装置上的一个或两个显示元件的角位移的真实度量。

Abstract: Technology disclosed herein automatically focus a camera based on eye tracking. Techniques include tracking an eye gaze of eyes to determine a location at which the user is focusing. Then, a camera lens may be focused on that location. In one aspect, a first vector that corresponds to a first direction in which a first eye of a user is gazing at a point in time is determined. A second vector that corresponds to a second direction in which a second eye of the user is gazing at the point in time is determined. A location of an intersection of the first vector and the second vector is determined. A distance between the location of intersection and a location of a lens of the camera is determined. The lens is focused based on the distance. The lens could be focused based on a single eye vector and a depth image.
