1. An active heads up display system comprising:
a driver monitoring system configured to track a gaze direction of a user in a three dimensional coordinate system, calculate one or more track values in response to a field of view of the user based on the gaze direction, and transmit the one or more track values on a first bus;
a gateway circuit configured to receive the one or more track values from the first bus, translate the one or more track values to one or more command values, and transmit the one or more command values on a second bus; and
a heads up display configured to receive the one or more command values from the second bus, generate a graphical presentation viewable by the user, project the graphical presentation at a current position in the three dimensional coordinate system in front of the user, and adjust the current position in the three dimensional coordinate system to an updated position centered within the field of view of the user in response to the one or more command values.
