1. Summary Eye-tracking is a widely applied tool to follow the human gaze direction. Due to the excessive technical development of eye-trackers, nowadays several fields of applications are available. A new field is food research where numerous questions can be answered by the analysis of gazing behaviour. The methodology might be applied not only in food marketing, but also in sensory analysis and consumer studies. In our article, we aim to introduce the principles of eye-tracking along with the major eye-movements and describe the meanings of the measured variables. Furthermore, several applications are introduced from food sciences.
2. What is eye-tracking? 
Eye-tracking is a technique which enables the researchers to follow the eye-movements of participants. It defines the position where a person is looking at any given time and the sequence in which his or her eyes are shifting from one location to another [1]. In this way, eye-tracking provides a wide range of variables which facilitate the evaluation of the participants’ gazing behaviour. Eye-tracking studies can be split into two major groups. Studies about humancomputer interaction belong to the first group in which researchers develop and design technologies that let humans interact with computers in novel ways. Those studies belong to the second group, which aim to uncover what a person is looking at. This is the group where the food-related studies are found.
