Gaze tracking technology provides information about the spatial coordinates of a person's point of attention in real-time using the distance to the camera, the position of the head, and the pupil of the eye. The first attempts at gaze tracking began at the end of the 19th century by a professor of psychology and education at Western Pennsylvania University to develop an effective method of the reading process when learning a language. () Nowadays, gaze tracking technology has found application in many fields, including medicine, psychology, marketing, and simulators.(). Although ready-made solutions already exist, they have some disadvantages: the need for special equipment (Tobii Eye Tracker), high cost (Tobii Aware), or dependence on external conditions. This research is aimed at creating a gaze tracking technology accessible to everyone who has devices with a reasonable camera.
