Abstract

The invention relates to an eye tracking arrangement that includes a camera configured to capture images of an eye at a first scanning rate, a laser velocimeter configured to capture an eye velocity of a movement of the eye by laser Doppler velocimetry at a second scanning rate and a control device configured to determine an absolute eye position based on the images, and track a gaze direction of the eye based on the absolute eye position and the eye velocity.
