In this paper, the movement of the pupils is a biometric indicator that analyzes the emotional state of a person. Eyetracking using infrared illumination based on the determination of the displacement vector between the centers of the pupil and the shine of the cornea gives results with high accuracy, provided that the human head is fixed. A method for determining the coordinates of the center of attention in the absence of fixation of the head without using infrared illumination is proposed. The accuracy of determining the coordinates of the center of attention is improved by moving from a coordinate system associated with a fixed head to a coordinate system associated with a moving center of the pupil.
