Utility
Method and System for Eye-tracker Calibration
6 Oct 22
The invention is related to a method and system for calibrating an eye tracking device configured to track a gaze point of a user on a display The method comprises: presenting a video on the display to a user, the video having a start size and a start position; tracking the gaze of the user, using an image sensor of the eye tracking device; and sequentially completing, for at least one calibration position, the steps of: resizing the video to a calibration size, wherein the calibration size is smaller than the start size, and translating the video to a calibration position; recording calibration data, using the eye tracking device, for the user viewing the video in the calibration position; and resizing the video to a second size that is greater than the start size.

Utility
Method of processing images of a users eye, associated systems and computer programs
13 Sep 22
A computer-implemented method of selecting a sequence of images of a user's eye for an eye tracking application wherein each image is captured when a stationary stimulus point is displayed to the user, the method comprising: for a plurality of different pairs of the images: comparing the pair of images with each other to determine an image-score that represents a degree of difference between the compared images; and calculating a sequence-score based on the image-scores for the plurality of pairs of images.

Utility
Gaze enhanced natural motion blur
23 Aug 22
There is provided systems, methods and computer program products for generating motion blur on image frames, comprising: obtaining gaze data related to an eye movement between consecutive images, determining movement of at least one object in relation to said gaze data by calculating the difference in position of said at least one object and said gaze data between the image frames, forming a motion blur vector and applying a motion blur on an image frame based on said motion blur vector.

Utility
Eye Event Detection
21 Jul 22
A method for detecting an eye event of a user using an eye tracking system, the method comprising capturing a first image of a first eye of a user, capturing an image of a second eye of the user a first period after capturing the first image of the first eye and a second period before capturing a next image of the first eye, capturing a second image of the first eye the second period after capturing the image of the second eye, determining that an eye event has occurred based on a difference between the first and second images of the first eye, and performing at least one action if it is determined that that an eye event has occurred.
