Abstract: An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.

Abstract: A method for controlling illuminators in an eye tracking system and a corresponding system are disclosed. The system includes a plurality of illuminators arranged such that each illuminator of the illuminators is located at a respective fixed position in relation to an eye of a user when using the system. The method comprises illuminating the eye of the user by means of the plurality of illuminators, and receiving an image of the eye of the user from an image sensor, the image resulting from the image sensor detecting light from the plurality of illuminators reflected from the eye of the user and reflected from an optic arrangement located between the plurality of illuminators and the eye of the user. The method further comprises determining a pupil position of a representation in the image of a pupil of the eye, and identifying one or more blobs in the image, wherein a blob is a representation in the image of a reflection from the optic arrangement of light from an illuminator of the plurality of illuminators. On a condition that there is at least one blob of the one or more blobs for which one or more predefined criteria are met, the method comprises identifying an illuminator of the plurality of illuminators associated with the at least one blob of the one or more blobs, and switching off the identified illuminator of the plurality illuminators.
