There are many possible applications for tracking the gaze of a person. For example, it can be used to analyze which areas of a website are attracting the most attention in order to optimize its layout. Another possible application is creating a barrier-free computer interaction for people with a limited ability to move. Some companies are specialized in gaze tracking technologies and offer different solutions. The downside of those solutions is, that they require special hardware and therefore are not affordable for everyone. This paper presents a method using only one camera for gaze tracking. It is based completely on free accessible software and only needs an ordinary camera, which is integrated into almost every laptop or can be connected as external hardware. The target is to proof that it is possible to obtain a usable gaze interaction while using simple hardware and algorithms. By this method it is possible to achieve resolutions of up to 17 columns and 15 rows, which is enough for special applications.
