The controller could encounter lateral conflicts (same altitude) between 2 and 3 aircraft and conflicts between aircraft that need to ascend or descend within the sector. After the simulation, a directed interview about the gaze pattern was conducted. Eye tracking data was recorded with a Tobii Pro Glasses 2, a head-mounted eye tracker. The gaze and scene camera video were captured with Tobii Pro Lab software and post-processed with **ArGaze** software library. As the eye tracker model is head mounted, ArUco markers were placed around the two screens to ensure that several of them were always visible in the field of view of the eye tracker camera. +A traffic simulation of moderate difficulty with a maximum of 13 and 16 aircraft simultaneously was performed by air traffic controllers.
