Abstract
The present invention relates to a stereo eye tracking technique. The eye tracking device comprises a processing unit configured and operable for receiving at least one image being indicative of a user's eye; identifying in the image a first data being indicative of pupil's parameters; receiving a second data being indicative of an alternative eye tracking, wherein the second data is more accurate than the first data; and correlating between the first and second data and determining a three-dimensional position and gaze direction of the user's eye.
