  • Method and system for 3D cornea position estimation
    Patent number: 11308321
    Abstract: There is provided a method, system, and non-transitory computer-readable storage medium for performing three-dimensional, 3D, position estimation for the cornea center of an eye of a user, using a remote eye tracking system, wherein the position estimation is reliable and robust also when the cornea center moves over time in relation to an imaging device associated with the eye tracking system. This is accomplished by generating, using, and optionally also updating, a cornea movement filter, CMF, in the cornea center position estimation.

  • EYE-TRACKING SYSTEM
    Publication number: 20210350554
    Abstract: An eye-tracking system configured to: receive a reference-image of an eye of a user, the reference-image being associated with reference-eye-data; receive one or more sample-images of the eye of the user; and, for each of the one or more sample-images: determine a difference between the reference-image and the sample-image to define a corresponding differential-image; and determine eye-data for the sample-image based on the differential-image and the reference-eye-data associated with the reference-image.

  • Image sensor for vision based on human computer interaction
    Patent number: 11089254
    Abstract: Techniques for reducing a read out time and power consumption of an image sensor used for eye tracking are described. In an example, a position of an eye element in an active area of a sensor is determined. The eye element can be any of an eye, a pupil of the eye, an iris of the eye, or a glint at the eye. A region of interest (ROI) around the position of the eye is defined. The image sensor reads out pixels confined to the ROI, thereby generating an ROI image that shows the eye element.
