A cockpit display system has a display, such as a multi-function display (MFD) for displaying a graphical representation of an input device when a sensor senses that an aviator's finger is proximate to the input device. The display graphically depicts in real-time the position of the aviator's finger relative to the buttons of the input device. The aviator's finger can be depicted by an icon, shading or highlighting. When the aviator lightly touches a button, the graphical representation of that button can for example be highlighted, shaded or colored. Furthermore, when the button is firmly depressed, the graphical representation of that button can change color or shading. The aviator can thus operate any awkwardly located input device by simply reaching toward the input device and then guiding his finger to the correct button by looking at the graphical representation of the input device.
