Eye movements are particularly important in aeronautics where operators rely on numerous sources of visual information. Eye-tracking reveals what we are looking at, but also the physical and psychological condition of an operator. The human perception, and more particularly the vision, is a vector of errors well known in human factors (tunnel effect, eye strain, etc.). The eyes can help finding where the attention is focused (gaze position), how the subject feels (fatigue), and interact with a system by eye movements [1]. Ocular interactions meet the need that HOTAS commands in aircraft are complexified by the high number of buttons and complex multiplexing. Oculometry has thus become a flagship sector of aeronautical research to understand human limits and interact more naturally with the system. Current solutions are largely based on video-based eye trackers, but this technology has some drawbacks: vibrations in the aircraft, visual field obstruction, and infrared illumination are signifiant issues that prevent eye trackers from being operational.
