Abstract: In one example, a head-mounted display (HMD) device includes a laser pattern generator to generate a pattern that is directed into an eye and reflected off of a retina and back out of the eye. A camera is included to capture an image of a reflected pattern from the retina. A pattern analyzer is included to determine a point spread function for the eye from the reflected pattern and to determine a focus plane for a user from the point spread function. A rendering engine renders the content on a display, wherein content at the focus plane is rendered at a higher resolution of the display, and content not at the focus plane is rendered at a lower resolution for the display.

Abstract: A depth sensing multiple camera system is described that uses depth sensing cameras. In one example, the camera system includes a primary auto-focus camera to capture an image of a scene at a first focus distance, the primary camera having a fixed field of view through different focus distances, a secondary auto-focus camera to capture an image of the same scene at a second focus distance, the secondary camera having a fixed field of view through different focus distances, and a processor having a port coupled to the primary camera to receive images from the primary camera and also coupled to the secondary camera to receive images from the secondary camera and to determine a depth map for the captured primary camera image using the captured secondary camera image.

Abstract: Systems, apparatuses, and/or methods may provide for identifying a face of a user by extracting contour information from images of shadows cast on the face by a facial features illuminated by a controllable source of illumination. The source of illumination may be left, center, and right portions of the light emitting diode (LED) display on a smart phone, tablet, or notebook that has a forward-facing two-dimensional (2D) camera for obtaining the images. In one embodiment, the user is successively photographed under illumination provided using the left, the center, and the right portions of the LED display, providing shadows on the face from which identifying contour information may be extracted and/or determined.
