Abstract: A gaze detection assembly comprises a plurality of infrared (IR) light emitters configured to emit IR light toward a user eye and an IR camera configured to sequentially capture IR images of the user eye. A controller is configured to, during a reference frame, control the plurality of IR light emitters to emit IR light toward the user eye with a reference intensity distribution. During the reference frame, an IR image is captured depicting a first glint distribution on the user eye. Based at least in part on the first glint distribution, during a subsequent frame, the plurality of IR light emitters are controlled to emit IR light toward the user eye with a subsequent intensity distribution, different than the reference intensity distribution. During the subsequent frame, a second IR image is captured depicting a second glint distribution on the user eye.

Abstract: Examples are disclosed herein that relate to eye imaging on a near-eye system using an eye-imaging camera that includes an array of lenses. One example provides a near-eye system, comprising an eye-imaging camera comprising an image sensor, and an array of lenses, each lens of the array of lenses configured to focus an image of an eye onto a different area of the image sensor than each other lens of the array of lenses.

Abstract: A head-mounted display device wearable by a user and supporting a mixed-reality experience includes a see-through display system through which the user can view a physical world and on which virtual images are renderable. At least one light source is configured to emit near infrared (IR) light that illuminates an eye of the user of the near-eye mixed reality display device. An imaging sensor is configured to capture reflections of the near IR light reflected from the eye of the user. A metalens is configured to receive the reflections of the IR light reflected from the eye of the user and direct the reflections onto the image sensor.

Abstract: In embodiments, an encoded micro pattern includes segments of encoded bits that can be optically-imaged by a digitizer. The position of each segment in the encoded micro pattern can be determined from the encoded bits in a segment. Each of the segments of the encoded micro pattern also includes a fiducial marker that indicates an orientation of a segment in the encoded pattern. The encoded bits of the encoded micro pattern can be integrated into a display surface of a display device, or integrated in a display screen that is positioned over the display surface of a display device.

Abstract: A scanning device includes a mode for generating a reproduced image on a standard page size from a large-sized original image. In this mode, the sampling rate of the scanning device in a motion direction is reduced. In addition, the captured image data in the sensor direction is downsampled by some factor. Position data that is generated as the image data is captured is also modified in accordance with the downsampling factor. A reproduced image is then generated from the modified image and position data and printed at a standard resolution.

Abstract: A portable scanner may comprise a first image detector and a second image detector placed in spaced apart relation to the first image detector. A plurality of position detectors is located between the first image detector and the second image detector for detecting a position of the portable scanner. A portable scanner may also comprise an image detector having a first side and a second side opposite said first side. A first plurality of position detectors is located adjacent the first side of the image detector. A second plurality of position detectors is located adjacent the second side of the image detector.
