Utility
Method and System for Determining a Current Gaze Direction
6 Jul 23
Method for determining a current gaze direction of a user in relation to a three-dimensional (“3D”) scene, the 3D scene being sampled by a rendering function to produce at least one projection image of the 3D scene, wherein the method comprises the steps: determining, by a reprojection means, a reprojection transformation to be applied to the projection image before being displayed so as to be visible to the user at a gaze time point; determining, by a gaze direction detection means, a physical gaze direction of the user at said gaze time point; and determining a modified gaze direction of the user at said gaze time point, the modified gaze direction being determined in relation to the 3D scene based on both the physical gaze direction and the reprojection transformation.

Utility
Object Orientation Estimation
18 May 23
The invention is related to a method of estimating an orientation of an object in an image, comprising the steps of: calculating, for the object in the image, a probability distribution of rotation; and estimating the orientation of the object from the calculated probability distribution; wherein the step of calculating the probability distribution and/or the step of estimating the orientation of the object are executed by a neural network; wherein the probability distribution is a matrix Fisher probability density function; and wherein the step of calculating the probability distribution includes approximating a normalizing function for the matrix Fisher probability density function.

Utility
Classification of glints using an eye tracking system
4 Apr 23
There is provided a method, system, and non-transitory computer-readable storage medium for classifying glints using an eye tracking system of a head-mounted device, by obtaining the position of any glint present in a current image of the first eye; obtaining a dataset indicative of the respective position of at least one glint detected in one or more previously captured images of the first eye; and, for each glint present in current image, determining if the position of the glint corresponds to the position of a glint in the dataset and, if the positions correspond, classify the glint as a static glint.
