  • Patent number: 10120442
    Abstract: A head mounted display (HMD) includes one or more light field cameras for tracking one or both eyes of a user wearing the HMD. The HMD optionally includes light sources positioned inside the HMD and that illuminate one or both of the eyes of the user. The light field camera captures a plenoptic image of the user's eye. The plenoptic image includes light intensity data and direction data of the captured light rays. An eye tracking system updates a 3D light field model of the user's eye based on depth information from the plenoptic image frame. The eye tracking system identifies an iris plane of the user's eye using the 3D light field model. The eye tracking system determines a gaze direction of the user's eye by identifying the normal to the center of the iris plane.

Cognitive load refers to the total amount of mental activity imposed on working memory in any one instant. Further, the system may aggregate the cognitive load data for one user over time, for many different users, and/or for many different users over time. The cognitive load may be determined for different portions of a displayed page, such as a document object model (DOM) included on the page. The cognitive load may be specified for different elements that make up the DOM. Also, cognitive load may be apportioned over several different DOM elements at one moment in time or over a period of time. Other embodiments are described herein.

The diffractive optical element is configured to direct a light beam (L1) towards at least a first designated area (A1) estimated to cover the at least one eye of the subject (180). Image registering means (150) registers light from the at least one light beam (L1, L2) having been reflected against the subject (180). The resulting data (DEYE) are produced in response to these light reflections, which resulting data (DEYE) represent movements of the at least one eye of the subject (180).

  • Patent number: 9872615
    Abstract: Methods for improving gaze tracking are presented. These methods eliminate the need for a separate initial calibration step to determine whether the subject is properly centrally fixated during testing. In one embodiment, whether the subject is centrally fixated is determined by identifying inlier and outlier gaze descriptors; the inliers are assumed to be associated with central fixation. This reduces the total time required for testing. These methods also improve the accuracy of gaze tracking during testing without the need for individual subject calibration. Instead, a database of reference eyes is used. The subject's eye can be compared to the reference eyes, and the mapping function for one or more reference matches can be used to estimate the subject's gaze direction. In another embodiment, previous calibration data from the same subject can be used to determine whether the subject is properly centrally fixated and/or the direction of the subject's gaze.

  • Patent number: 9736373
    Abstract: Technologies for power optimization of light sources include an imaging device to generate a captured image of a subject. The imaging device analyzes the captured image to determine, in the captured image, a location of the subject's eye relative to the imaging device, an iris-pupil contrast of the subject's eye, and a glint intensity of glints present on the subject's eye. The imaging device determines, for each of a plurality of light sources, an illumination efficiency based on a distance between the camera and the subject's eye, a distance between the light source and the subject's eye, an incidence angle of the light source relative to the subject's eye, and a power profile of the light source. The imaging device determines an amount of power to supply to each light source to reduce a total cumulative power supplied to the light sources based on one or more power constraints.

  • Patent number: 9727136
    Abstract: Examples relating calibrating an estimated gaze location are disclosed. One example method comprises monitoring the estimated gaze location of a viewer using gaze tracking data from a gaze tracking system. Image data for display via a display device is received and, without using input from the viewer, at least one target visual that may attract a gaze of the viewer and a target location of the target visual are identified within the image data. The estimated gaze location of the viewer is compared with the target location of the target visual. An offset vector is calculated based on the estimated gaze location and the target location. The gaze tracking system is calibrated using the offset vector.

  • Patent number: 9715781
    Abstract: A system and method is disclosed for calibrating the location of a player's gaze at a video display of a gaming machine. The system and method includes capturing images of the player's gaze with a camera while displaying a plurality of reference symbols at locations on the display during serial display of game video content. Also, a processor creates control signals that represent the direction of the player's gaze relative to the location of the plurality of symbols on the display of the gaming machine. The processor develops a data set based on the control signals and the locations of the plurality of reference symbols to develop a data set. Further, the system and method includes calibrating the location of the player's gaze using the data set with the location s of the plurality of reference symbols on the display.

  • Patent number: 9713420
    Abstract: An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

  • Patent number: 9700203
    Abstract: A handheld testing device includes a focus light source, which can serve as a focal point for a subject being tested for nystagmus, and multiple timers, which can be used to control tactile and other feedback indications. The timers can include an Equal Tracking (ET) timer and Smooth Pursuit (SP) timer, each of which controls a series of tactile feedback indications that can assist a user in properly performing ET and SP portions of a Horizontal Gaze Nystagmus test. Other test timers configured to generate feedback indications for use in various medical examinations and drug evaluations are also included. The handheld device can include multiple light sources in addition to the focus light source, for example an ultra-violet (UV) source or a white light source. Various fixed interval timers can also be included in the handheld testing device.

  • Patent number: 9652893
    Abstract: Embodiments are described herein for determining a stabilization plane to reduce errors that occur when a homographic transformation is applied to a scene including 3D geometry and/or multiple non-coplanar planes. Such embodiments can be used, e.g., when displaying an image on a head mounted display (HMD) device, but are not limited thereto. In an embodiment, a rendered image is generated, a gaze location of a user is determined, and a stabilization plane, associated with a homographic transformation, is determined based on the determined gaze location. This can involve determining, based on the user's gaze location, variables of the homographic transformation that define the stabilization plane. The homographic transformation is applied to the rendered image to thereby generate an updated image, and at least a portion of the updated image is then displayed.
