Au moins une caméra et une pluralité de détecteurs de proximité sont installés dans le véhicule. La caméra est utilisée pour acquérir un flux d'images d'un visage d'un conducteur. Ladite image du visage est ensuite analysée pour déterminer la direction de la vision du conducteur. Un détecteur de proximité détecte la proximité de la main du conducteur et un système basé sur la localisation pour localiser le véhicule. Les variables d'entrée acquises mentionnées ci-dessus servent à commander le niveau de luminosité des surfaces d'affichage, celles-ci incluant la surface d'affichage d'un tableau de bord, l'affichage d'une commande sur la pile centrale, un écran d'affichage secondaire, et les éléments de commande sur le volant de direction.
