The objective of this study is to determine which oculomotor variables are most used in eye tracking research oriented to the areas of computer science and systems engineering. To this end, 26 academic papers published between 2012 and 2018 were reviewed. An analysis of hierarchical clusters was carried out, from which three large groups emerged, one exploratory in which ocular monitoring is used to gain a deeper knowledge of a phenomenon, another comparative in which we want to find out which of two or more processes is more efficient and above all intuitive, using eye tracking as a tool to determine that efficiency. A third group would be that of studies in which eye tracking is used as a user-computer interface. The variables most used are fixation time (50%), average duration of fixation (46.3%), linearity (42.3%), fixation rate (34.6%), fixation count (26.9%), and average duration of fixation. Relevant fixations (23.1%). These variables are present in the three large groups in which the sample is divided. In addition, a review is made of the contexts in which the least used variables are useful.
