Using Scanpath Analysis for Affects Detection in Computer Users

In interpersonal relations, interlocutor’s emotions may be easily detected by facial and oculomotoric expressions. Several books are devoted to recognition so called body language expressions (e.g. [18]) several others to avoiding of uncontrolled disclosure of spontaneous affects (e.g. [14]).
