Abstract
A method for calibrating an eye tracker includes drawing the attention of a user to a calibration target. At least one positioning camera and at least one computer is employed to determine the position of the calibration target and the eye tracker coordinate system relative to each other. The calibration parameters of a gaze line are determined, to the calibration target, in a first coordinate system. The above steps are repeated, thereby providing a desired part of a gaze range and calibration targets distribution. The calibration data is then stored. A method of calibrating and using an eye tracker and a method of calibrating an eye tracker for use with a display are also provided.
