Abstract
A vehicle data display device which draws the attention of the driver to a particular sector of the road scene, including an optical system that presents to the driver a reduced virtual image of the road scene embellished with a luminous signal. The luminous signal can be used to designate a target for the driver and can be under the control of an onboard driving assistance system. The vehicle data display device can be integrated into the steering column or dashboard of the vehicle and facilitates perception of driving assistance or navigational data without the driver having to turn his attention away from the road.
