Abstract
An active heads up display system includes a driver monitoring system, a gateway circuit, and a heads up display. The driver monitoring system tracks a gaze direction of a user, calculates track values in response to a field of view of the user based on the gaze direction, and transmits the track values on a first bus. The gateway circuit receives the track values from the first bus, translates the track values to command values, and transmits the command values on a second bus. The heads up display receives the command values from the second bus, generates a graphical presentation viewable by the user, projects the graphical presentation at a current position in front of the user, and adjusts the current position to an updated position centered within the field of view of the user in response to the command values.
