1. A visual search assistance method for an occupant of a vehicle, the method comprising: dynamically determining a desired line-of-sight vector from an occupant of the vehicle to a visual target; dynamically determining, with an onboard tracking system of the vehicle, an actual line-of-sight vector for the occupant of the vehicle, the determined actual line-of-sight vector being temporally associated with the determined desired line-of-sight vector; comparing the determined actual line-of-sight vector against the determined desired line-of-sight vector to obtain a difference measurement; and generating a notification when the obtained difference measurement exceeds a threshold value, the notification providing guidance to redirect a gaze direction of the occupant toward the visual target.
