AIR SPACED OPTICAL ASSEMBLY WITH INTEGRATED EYE TRACKING
First Claim
1. A head-mounted display (HMD) comprising:
- an electronic display;
an optical assembly comprising a front optical element in series with a back optical element adjacent to the electronic display, the back optical element comprises a first surface adjacent to the electronic display and a second surface opposite to the first surface configured to reflect light of a defined range of wavelengths;
an illumination source positioned between the front optical element and the back optical element, the illumination source configured to illuminate the second surface of the back optical element with light having one or more wavelengths within the defined range of wavelengths;
an imaging device positioned between the front optical element and the back optical element, the imaging device configured to capture an image of a user'"'"'s eye illuminated with light emitted from the illumination source having the one or more wavelengths reflected from the second surface of the back optical element; and
a controller coupled to the imaging device, the controller configured to determine an orientation of the user'"'"'s eye based on the captured image, andwherein the system is configured to adjust presentation of one or more images displayed on the electronic display, based on the determined orientation of the user'"'"'s eye.

Abstract
A head-mounted display (HMD) includes a display, an optical assembly and an eye tracking system that determines user'"'"'s eye tracking information. The optical assembly comprises a front optical element in series with a back optical element adjacent to the display. One surface of the back optical element is coated to reflect infrared (IR) light. The eye tracking system includes an illumination source and an imaging device positioned between the front optical element and the back optical element. The illumination source emits IR light that illuminates the coated surface and reflects towards the user'"'"'s eye. The imaging device captures an image of the user'"'"'s eye based on light reflected from the user'"'"'s eye and from the coated surface. The eye tracking information is determined based on the captured image. The HMD adjusts presentation of images displayed on the display, based on the eye tracking information.
