An apparatus for tracking a gaze of a user is provided. The apparatus includes a memory including computer executable instructions; and a processor that reads and executes the computer executable instructions. The instructions cause the processor to receive gaze information associated with the gaze of the user; based on the gaze information, determine whether change information associated with the gaze of the user is greater than a threshold value; and in response to determining the change information is greater than the threshold value, predict at least one from among a gaze vector of the gaze of the user and a location of a gaze target of the gaze of the user based on a kinematic model. The gaze tracking apparatus may be used in a vehicle to perform vehicle functions based on the gaze of a user of a vehicle or to update gaze modeling database.
