A computer-implemented method for controlling a vehicle interface system in vehicle includes receiving images of a driver from an image capture device and determining a population group based on the images. The method includes identifying a human perception condition of the driver that is characteristic of the population group. The human perception condition limits an ability of the driver to perceive a driving situation of a vehicle operation and a stimulus output that conveys information to the driver in the vehicle about the driving situation of the vehicle operation. The stimulus output is controlled by the vehicle interface system. The method includes modifying the stimulus output into an optimal stimulus output that can be perceived by the driver with the human perception condition, and controlling the vehicle interface system to provide the optimal stimulus output to the driver during the vehicle operation.
