Abstract
In at least one embodiment, the eye tracker module (100) comprises a radiation unit (1) and a detection unit (2). The radiation unit is configured to project a 2D-structured pattern (PI) onto an eye (3) of a user. The detection unit is configured to capture an image (DI) of the 2D-structured pattern as reflected by the eye.
Claims20
An eve tracker module comprising:
- a radiation unit;
- and
- a detection unit), wherein
- the radiation unit is configured to project a 2D-structured pattern onto an eye of a user, wherein
- the detection unit is configured to capture an image of the 2D-structured pattern as reflected by the eye, wherein
- the eye tracker module comprises a housing and the housing laterally surrounds the radiation unit and the detection unit.

An eye tracking method comprising
- projecting a 2D-structured pattern onto an eye of a user with the help of a radiation unit,
- capturing an image of the 2D-structured pattern as reflected by the eye with the help of a detection unit,
- determining a gaze information depending on the captured image, wherein the gaze information is representative for the location of the pupil of the eye, wherein
- determining the gaze information comprises comparing the captured image with a reference image, wherein the reference image is an image of a 2D-structured pattern;
- and
- updating the reference image depending on at least one image captured previously with the help of the detection unit.

An eye tracker system comprising:
- a radiation unit which is configured to project a 2D-structured pattern onto the eye of a user;
- and
- a detection unit which is configured to capture an image of the 2D-structured pattern as reflected by the eye,
- wherein
- the eye tracker system is configured to:
- determine a gaze information depending on the captured image, wherein the gaze information is representative of the location of the pupil of the eye, wherein
- the eye tracker system configured to determine the gaze information comprises the eye tracker system configured to:
- compare the captured image with a reference image, wherein the reference image is an image of a 2D-structured pattern;
- and
- update the reference image depending on at least one image captured previously with the help of the detection unit.
