Geometry issues of a gaze tracking system


Conference Paper

One of the most confusing aspects that one meets as he introduces himself into gaze tracking is the variety, in terms of hardware equipment, of available systems providing solutions to the same matter, i.e. determining subject's gaze. Calibration permits adjusting trackers based on different hardware and image features to the subject. The negative aspect of calibration is that it permits the system to work properly but at the expense of a lack of control over the intrinsic behavior of the tracker. The objective of this work is to overcome this obstacle to explore more deeply the elements of a tracker from a purely geometrical point of view. Alternative models based on image features are evaluated. As result of this study a model has been constructed based on minimal calibration using one camera and multiple lighting with acceptable accuracy level. © Springer-Verlag Berlin Heidelberg 2007.
