<p>A device for maintaining the vigilance of a motor vehicle operator (22). 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 (26), unrelated to the motor vehicle (12), which is projected (37-38) or otherwise transmitted from below the normal line of sight of the operator, while the other illustrates transmission (50, 52) of the image, also unrelated to the motor vehicle, from above the vehicle operator. The invention overcomes "road hypnosis" or the inattentiveness by maintaining the operator's interest, thereby putting the operator's psychological perceptive apparatus in a high state of readiness.</p> |
