Abstract

This paper presents new methods to calibrate a headmounted Eye Tracker ET automatically as well as a new way to obtain an estimated point of regard POR taking account of the parallax Calibration is performed in real time it is easy for the user who just needs to look at one calibration pattern for a few seconds before starting This method provides a very important couple of points which helps to use a local relationship to compute the POR instead of a global one This approach significantly improves the precision of the points of regard when the scene camera is mounted with a short focal lens An estimation of POR when the user looks somewhere outside the calibration distance is also proposed This estimation is based on an ET modelling such as a stereovision system to take account of the parallax effect The aim of this study is to simplify the use of ET techniques for “noninitiated” people especially here learner drivers
