Methods and systems for detecting driver attention to objects

The invention discloses methods and systems for detecting driver attention to objects. The methods and systems are provided for detecting an attention of an occupant of a vehicle. In one embodiment, a method includes calculating, by a processor, a first gaze vector in a three-dimensional space based on a first vehicle location, a first vehicle orientation, and a first gaze direction; calculating, by the processor, a second gaze vector in the three-dimensional space based on a second vehicle location, a second vehicle orientation, and a second gaze direction; and determining the attention of the occupant based on the first gaze vector and the second gaze vector.
