  • Patent number: 10534982
    Abstract: Techniques for generating 3D gaze predictions based on a deep learning system are described. In an example, the deep learning system includes a neural network. The neural network is trained with training images. During the training, calibration parameters are initialized and input to the neural network, and are updated through the training. Accordingly, the network parameters of the neural network are updated based in part on the calibration parameters. Upon completion of the training, the neural network is calibrated for a user. This calibration includes initializing and inputting the calibration parameters along with calibration images showing an eye of the user to the neural network. The calibration includes updating the calibration parameters without changing the network parameters by minimizing the loss function of the neural network based on the calibration images. Upon completion of the calibration, the neural network is used to generate 3D gaze information for the user.

  • Patent number: 10335027
    Abstract: In exemplary implementations of this invention, an aberrometer is used to measure the refractive condition of any eye. An artificial light source emits light that travels to a light sensor. Along the way, the light enters and then exits the eye, passes through or is reflected from one or more spatial light modulators (SLMs), and passes through an objective lens-system. The SLMs modify a bokeh effect of the imaging system (which is only visible when the system is out-of-focus), creating a blurred version of the SLM patterns. The light sensor then captures one or more out-of-focus images. If there are refractive aberrations in the eye, these aberrations cause the SLM patterns captured in the images to be distorted. By analyzing differences between the distorted captured patterns and the undistorted SLM patterns, refractive aberrations of the eye can be computed and an eyewear measurement generated.

  • Patent number: 10314483
    Abstract: The present invention provides for very fast detection of gaze direction using retro-reflected light from the ocular fundus that is cost-efficient, small, and portable. These eye trackers are useful in many areas of science and technology, including but not limited to remote control, space, defense, medical and psycho-physiological applications, to identify for example subtle neurologic deficits that occur with cerebellar or vestibular disorders, Parkinson's disease, strokes, traumatic brain injury, possible concussions during sports matches, some forms of reading disability, or simply fatigue or inebriation. In ophthalmology, with two such devices operating simultaneously, the variability of relative eye alignment over time can be measured, without requiring individual calibration, and without requiring fixation on a specified target, ideal for use with small children.

  • Patent number: 10307054
    Abstract: A method includes obtaining an image of an eye in a bright-pupil imaging mode in which a retinal retro-reflection complements the image of the eye in the bright-pupil mode, and obtaining an image of the eye in a dark-pupil imaging mode in which a cornea-scleral retro-reflection complements the image of the eye in the dark-pupil mode. One of the bright-pupil imaging mode and the dark-pupil imaging mode is selected based on quality of obtained images.

  • Patent number: 10311583
    Abstract: Provided is a method to easily detect eye motions in the eye moving direction, which has resistance to a fluctuation in background light and to a displacement of the position of a camera. The method includes the steps of: detecting a white area of the eye from the eye area; determining a blood vessel image to be used for a template blood vessel image in the white area of the eye; detecting a nth blood vessel image, which matches the template blood vessel image; calculating a nth moving amount of the eye based on a difference between the reference position and the detection position of the nth blood vessel image, which matches the template blood vessel image; and calculating a nth rotation angle of the eye to detect eye motions in the information processing apparatus.

  • Patent number: 10304022
    Abstract: Systems, methods, and computer-readable media are disclosed for capturing gaze data for a sports participant over the course of a sports match, identifying a key performance indicator (KPI) corresponding to a sports domain with which the sports match is associated, and generating KPI data corresponding to the KPI. Report data indicative of the KPI data may be generated and presented to the sports participant in-match or post-match. KPI data for a player may be aggregated across multiple sports domain KPIs and multiple sports matches and analyzed to determine player activity patterns. The player activity patterns may indicate statistical differences in KPIs for the player in relation to different in-match scenarios. Recommendations may be provided to the player for improving the player's performance with respect to various KPIs.

  • Patent number: 10297136
    Abstract: There is provided a head-mounted display, a notification apparatus, a notification system, a notification method, and a program that allow a person not wearing a head-mounted display to know that a user still continues to wear a head-mounted display after a notification that a wearing time of the head-mounted display of this user has exceeded a predetermined time. A wearing time determination block determines a wearing time of the head-mounted display of the user. A notification block executes a first notification to the user if the wearing time has exceeded a first time and, when the wearing time has exceeded a second time longer than the first time, and executes a second notification to a person not wearing the head-mounted display.

  • Patent number: 10285586
    Abstract: A method of compensating for distortion, in a plurality of retinal image frames, arising from eye movement receives at least one reference image frame and plural other image frames of the eye. For each frame, the method determines a plurality of shifts relative to the reference image frame, and an initial eye movement trajectory based on at least an initial reference frame distortion, and the shifts within each of said other image frames. The method estimates a current reference frame distortion using the initial trajectory and the shifts within each of the other image frames, and a current eye movement trajectory based on the estimated current reference frame distortion, and the shifts within each of said other image frames to provide a smooth transition between the other image frames in the eye movement. With this the method compensates for distortion in said frames using the current eye movement trajectory.

  • Patent number: 10271722
    Abstract: To facilitate observation of object(s), an imaging process can include or an imaging device can perform detecting a position of a focusing point of an eye of a user, determining, according to the position of the focusing point, an object gazed by the user, and changing a size of target imaging of the gazed object on the fundus of the user according to a predetermined zooming rule. The size of the target imaging of the gazed object on the fundus of the user can be automatically changed by optical zooming processing, so that the user can observe the gazed object at a modest distance and with a moderate size of the imaging on the fundus, and therefore it may be convenient for the user to observe the gazed object.

    Abstract: A pupillometer system includes a computer, a camera, and a testing compartment provided in the form of a substantially hemispheric bowl, where the substantially hemispheric bowl includes a plurality of chromatic beam emitters arranged about a visual field forming a plurality of visual field testing points. The plurality of chromatic beam emitters generate a first chromatic stimulus that stimulates a first anatomical structure of an eye and a second chromatic stimulus that stimulates a second anatomical structure of the eye where the first anatomical structure is different than the second anatomical structure. The camera records a pupil response of one or more eyes. The computer generates quantitative pupillary light reflex (PLR) measurements of the PLR in response to the stimuli, determines at least one PLR response ratio, and determines a state of health of the one or more eyes utilizing the at least one PLR response ratio.
