    Abstract: A head-mounted device may have a head-mounted support structure. Gaze tracking systems may be supported by the support structure so that the gaze of a user may be monitored. Lenses may be supported by the support structure. Display systems may provide computer-generated images to the user while the user is viewing real-world objects through the lenses. The gaze tracking systems may include image-sensor-based systems such as glint-based systems. A glint-based gaze tracking system may include light-emitting devices that emit light beams that create eye glints on the surface of a user's eyes and may include an image sensor that measures the eye glints to gather information on the user's gaze. A low-power gaze tracking system may be included in the head-mounted device. The low-power gaze tracking system may use light detectors to measure the magnitudes of respective light reflections of the light beams.

  • Patent number: 11803237
    Abstract: Disclosed herein is utilization of photosensor-oculography along with a video camera to implement a novel form of eye tracking, which can be important for many applications, such as augmented reality (AR) on smartglasses. In one embodiment, an eye tracking system includes a photosensor-oculography device (PSOG) that emits light and takes measurements of reflections of the light from an eye of a user, and a camera that captures images of the eye. A computer calculates values indicative of eye movement velocity (EMV) based on the measurements of the reflections obtained by the PSOG. These values then are used to determine how data is read from the camera, which can save power in some cases: the computer reads data from the camera at a higher bitrate when the values are indicative of the EMV are below a threshold compared to when the values are indicative of the EMV are above the threshold.

  • Patent number: 11509816
    Abstract: An image processing apparatus includes a display unit configured to display an image captured via an optical system, an estimation unit configured to estimate a gazing point position of a user on a display unit, and a control unit configured to change a zoom position of an image displayed on the display unit. When start is instructed of image pickup assist control, the control unit zooms out the image displayed on the display unit from a first zoom position to a second zoom position on more wide-angle side than the first zoom position. When stop is instructed of the image pickup assist control, the control unit zooms in on a zoom-out image from the second zoom position to a third zoom position on more telephoto side than the second zoom position, based on the gazing point position estimated by the estimation unit.

  • Patent number: 11490809
    Abstract: A system and/or method for measuring a human ocular parameter comprises a human-wearable face shield which has an eye sensor, a head orientation sensor, and an electronic circuit, and a face shield. The eye sensor comprises a video camera that measures horizontal eye movement, vertical eye movement, pupillometry, and/or eyelid movement. The head orientation sensor measures pitch and/or yaw of the wearer's face. The electronic circuit is response to the eye sensor and the head orientation sensor and measures an ocular parameter such as vestibulo-ocular reflex, ocular saccades, pupillometry, pursuit tracking during visual pursuit, vergence, eye closure, focused position of the eyes, dynamic visual acuity, kinetic visual acuity, virtual retinal stability, retinal image stability, foveal fixation stability, or nystagmus.

  • Patent number: 11478141
    Abstract: Methods and systems for assessing a visual field of a person are provided. Information can be presented to a person undergoing a visual field testing in a manner that utilizes the person's natural tendency to look at an object that is displayed so that it attracts the person's attention. A fixation target can be displayed on a display viewed by a user. Once it is determined that the user has viewed the fixation target and the person's eye(s) location is determined, a test target is displayed on the display in a location corresponding to a location on the user's visual field. The test target is determined to be either detected or missed based on user input acquired as the user is viewing the display.

  • Patent number: 11375891
    Abstract: Methods, systems, and devices to improve the assessment of visual function and overcoming limitations of current methods to identify the visual function that potentially could be reached by a given eye. Multiple eye tests including visual stimuli plus optical measurement components, and methods to combine the results, identify and quantify sources of decreased vision resulting from optical sources, such as a lens and cornea as distinguished from retinal sources. By identifying potentially correctable optical sources of decreased vision, and overcoming physiological limitations such as size of the eye's pupil, the visual benefits of treatment such as by cataract or corneal surgery are distinguished from retinal pathology that requires medical intervention. The devices and methods provide metrics that include an expected value of the visual function and sources of variability including both optical and neural components, to guide treatment and improve clinical trials.
