Gaze based systems and methods are used to aid traffic controllers and/or pilots. A gaze line of an eye of the user viewing the display is tracked using an eyetracker. An intersection of the gaze line of the eye with the display is calculated to provide continuous feedback as to where on the display the user is looking. A trace of the gaze line of the eye is correlated with elements of a situation. The user's awareness of the situation is inferred by verifying that the user has looked at the elements of the situation. In an embodiment, the user is notified of the situation when it is determined that the user has not looked at the elements of the situation for a predetermined period of time. The notification is automatically removed once it is determined that the user has looked at the elements of the situation.
