    Abstract: An apparatus comprising a diffractive combiner having a front side, a back side, and a combiner optical axis running substantially through the diffractive combiner and normal to the back side. A display unit having a display optical axis that directs the display light along the display optical axis toward the diffractive combiner. An eye-tracking sensor having a sensor optical axis that is positioned to receive eye-tracking radiation reflected by the diffractive combiner along the sensor optical axis. The combiner optical axis, the display optical axis, and the sensor optical axis intersect each other at the diffractive combiner.

    Abstract: Embodiments of an apparatus comprising a light guide including a proximal end, a distal end, a display positioned near the proximal end, an eye-measurement camera positioned at or near the proximal end to image eye-measurement radiation, a proximal optical element positioned in the light guide near the proximal end and a distal optical element positioned in the light guide near the distal end. The proximal optical element is optically coupled to the display, the eye-measurement camera and the distal optical element and the distal optical element is optically coupled to the proximal optical element, the ambient input region and the input/output region. Other embodiments are disclosed and claimed.

    Abstract: Embodiments are described of an apparatus including an eyepiece having a front surface, a back surface spaced apart from the front surface, and an edge forming a perimeter of the eyepiece. The eyepiece includes an angled surface to direct light eye-measurement light reflected from an eye into the eyepiece and to direct display light out of the eyepiece to the eye. A first waveguide is formed in the eyepiece and extending from the angled surface to the edge, the first waveguide being optically coupled to a first portion of the angled surface having a first surface treatment. And a second waveguide is formed in the eyepiece and extending from the angled surface to the edge, the second waveguide being optically coupled to a second portion of the angled surface having a second surface treatment.

    Abstract: A method for aligning an image on a mobile device disposed within a head-mounted display (HMD) housing includes: detecting a request to align an image on a touchscreen of a mobile device; detecting, on the touchscreen, a first detected location corresponding to a first touchscreen input event; determining a first displacement of the first detected location with respect to a first target location of the first touchscreen input event; and transposing the image on the touchscreen based on the first displacement. A virtual reality system includes: a mobile device having a touchscreen configured to display an image; and a HMD housing having a first contact configured to generate a first input event at a first location on the touchscreen when the mobile device is disposed within the HMD housing.

    Abstract: An apparatus comprising a diffractive combiner having a front side, a rear surface, and an optical axis running substantially through the center of the diffractive combiner and normal to the back side. A display unit directs display light toward the back side of the diffractive combiner; the display unit positioned at a first angle relative to the optical axis, and the display light having a first range of wavelengths. An eye-tracking sensor receives eye-tracking radiation reflected by the back side of the diffractive combiner, the eye-tracking sensor positioned next to the display unit at a second angle relative to the optical axis, the second angle being different than the first angle and the eye-tracking radiation having a wavelength outside the first range of wavelengths. Other embodiments are disclosed and claimed.
