Abstract: A device (1300) adapted to be worn by a user is disclosed, comprising an optical element, a light source and a sensor. The optical element is adapted to be arranged in front of an eye (1312) of the user and formed of a light-transmitting material allowing the user to see through the optical element, wherein the light source is arranged on the optical element and adapted to illuminate at least a part of the eye of the user. Further, the sensor is adapted to capture light which has been emitted from the light source and reflected on the eye. A system for is also disclosed, comprising such a device and a processor adapted to determine a gaze direction of the user based on the light captured by the sensor.

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.
