  We present a set of results obtained with an innovative eye-tracker based on
magnetic dipole localization by means of an array of magnetoresistive sensors.
The system tracks both head and eye movements with a high rate (100-200 Sa/s)
and in real time. A simple setup is arranged to simulate head and eye motions
and to test the tracker performance under realistic conditions. Multimedia
material is provided to substantiate and exemplify the results. A comparison
with other available technologies for eye tracking is drawn, discussing
advantages (e.g. precision) and disadvantages (e.g. invasivity) of the diverse
approaches, the presented method standing out for low cost, robustness and
relatively low invasivity.
