**Review of ITU Gaze Tracking Library**

ITU Gaze Tracker is an application for controlling the movement of the mouse pointer on Windows operating systems, just by moving the head. Depending on the movement of the head, the application moves the mouse respectively. The best way to explain how this works is through an example experiment. For this purpose I used a !YouTube video demo example, available on this link: https://www.youtube.com/watch?v=75KRipM2W5c
