Utility
Eye gaze tracking system, associated methods and computer programs
21 Nov 23
An eye tracking system configured to: receive a plurality of right eye images of a right eye of a user; receive a plurality of left eye images of a left eye of a user, each left eye image corresponding to a right eye image in the plurality of right eye images; detect a pupil and determine an associated pupil signal, for each of the plurality of right eye images and each of the plurality of left eye images; calculate a right eye pupil variation of the pupil signals for the plurality of right eye images and a left eye pupil variation of the pupil signals for the plurality of left eye images; and determine a right eye weighting and a left eye weighting based on the right eye pupil variation and the left eye pupil variation.

Utility
Gaze detection method and apparatus
25 Jul 23
A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest; detecting the direction of the user's gaze; using the bitmap to determine if the detected user's gaze is directed in the direction of the zone of interest.

Method for mounting functional elements in a lens
11 Jul 23
A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.

Utility
Driver alertness detection method, device and system
27 Jun 23
The invention is related to a method for driver alertness detection, The method comprises the steps of determining a vanishing point of a vehicle in motion; determining over time, by an eye tracking device, a set of gaze points of the driver of the vehicle; determining a gaze movement from the set of gaze points; and identifying an alertness of the driver, based on a direction of the gaze movement relative to the vanishing point being outward.

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.
