Abstract: The present invention is directed toward head-up display based safety devices for use in motor vehicles. The first aspect of the present invention is directed towards facilitating accurate driver operation of a driver operable device deployable in a motor vehicle without the need for a driver to turn his eyes downwards toward its control panel. This can be achieved by either providing an icon representative of the position of a driver's fingertip positioned for operating the driver operable device for superimposition on a head-up display image of the layout of its control panel, or employing a speech recognition module to issue output control signals in accordance with spoken commands. The second aspect of the present invention is directed toward projecting a head-up display image of a driver's rear field of vision including wireframe images of objects located therein.
