Eye movements were recorded at 60Hz using a Smart Eye remote eye tracker (Smart Eye AB, Sweden). The system detects human face/head movements, eye movements, and gaze direction. Gaze direction and eyelid positions are determined by combining image edge information with 3-D models of the eye and eyelids. As presented in Fig 3, the system uses five cameras integrated into the cockpit. A major advantage of using several cameras is that eye and head tracking can be maintained despite significant head motions (translation and rotation) or occlusion of one of the cameras by the participant (e.g., by its hand). Smart eye system allows to design a 3D environment and to establish calibration points (at the vicinity of AOI). When the world model is designed, we just need to operate an automatic calibration for each participant.
