The Tobii eye-tracker device reference T-120 was designed to record eye movements in observers whose face is parallel to the monitor. However, by inverting the face position, the sampling rate of captured data may decrease, as well as the recorded eye fixations. The present study wanted to compare the differences in sampling rates and durations of ocular fixations when inverting the face 1800, when performing a visual task for 20 s. 96 participants, divided into two groups, observed the same visual stimulus in front of a Tobii T-120 eye-tracker device, half in a normal position, the other half with their faces inverted. The results show that there are differences in the sampling of the captured data and also in the durations of ocular fixations in a salient area of the stimulus, with a significant decrease in those who were in an inverted position. It is concluded that the variation in the position of the eyes affects both the sample of the captured data and the durations of ocular fixations, a fact that has to be estimated when recording eye-movements with remote eye-trackers like the Tobii T-120. The inversion of the face exerts an effect on data sampling concerning oculomotor activity. This decrease of the amount of ocular data is an important issue to take into consideration when conducting research projects in which face positions are atypical in relation to the standards suggested by manufacturers of the Tobii-T-120.
