First Claim
1. An apparatus for use in a ground vehicle having a windshield through which a driver may view conditions in the direction of travel of the ground vehicle, the apparatus comprising:
- a signal source for generating a video signal comprising a series of moving visual images constituting a visual program of unpredictable, new information unrelated to the operation of the ground vehicle; and
a visual display means connected to said signal source for presenting a visual display of said video signal to the driver, the video display utilizing a small fraction of the total windshield area and disposed in a position slightly above the line of sight of the driver toward the direction of travel of the ground vehicle,whereby the driver can observe said visual program while operating the ground vehicle and such observation will maintain the field of view of the driver in the proper position for operation of the ground vehicle and will maintain the driver in a mental state of vigilance.

Abstract
A device for maintaining the vigilance of a motor vehicle operator. Two preferred embodiments, maintaining the operator'"'"'s attention toward the direction of developing traffic conditions, with a visual system focused at infinity, are disclosed. One shows an image which is projected or otherwise transmitted from below the normal line of sight of the operator, while the other illustrates transmission of the image from above the vehicle operator. The invention overcomes "road hypnosis" or other inattentiveness by maintaining the operator'"'"'s interest, thereby putting the operator'"'"'s psychological perceptive apparatus in a high state of readiness.
