There are numerous cues which influence human visual attention. Some of the cues cannot be explored by theconventional eye-tracking studies which makes use of a pictorial data presented to the observers on common displays.Depth perception occurs naturally in the real three-dimensional environment and, therefore, the depth cues are one ofthem. However, the eye-tracking studies in the real environment and their evaluation are complicated to carry out with arelevant number of participants while maintaining the laboratory conditions. We propose an experimental studymethodology for exploring the depth perception tendencies during the free-viewing task on a widescreen display in alaboratory. This method is beyond the current hardware capabilities of the static eye-trackers mounted on the displays.Therefore, the eye-tracking glasses were used in the study to measure the attention data. We carried out the proposedstudy on a sample of 25 participants and created a novel dataset suitable for further visual attention research. The depthperception tendencies on a widescreen display were evaluated from the acquired data and the results were discussed inthe context of the previous similar studies. Our results revealed some differences in the depth perception tendencies incomparison to the previous studies with the two-dimensional pictorial data and resembled some depth perceptiontendencies observed in the real environment.
