Abstract

The present invention is directed to a visual mobility assist device which provides a conformal, augmented display to assist a moving body. When the moving body is a motor vehicle, for instance (although it can be substantially any other body), the present invention assists the driver in either lane keeping or collision avoidance, or both. The system can display objects such as lane boundaries, targets, other navigational and guidance elements or objects, or a variety of other indicators, in proper perspective, to assist the driver.
