Abstract
A driver operates a car by watching an intersection number and an arrow which indicate direction by reflecting the information in the front windshield. The indicated arrow direction shows the direction in which the car is advancing. Accordingly, the driver does not need to observe the indicator displayed on the dashboard during operation and can drive more safely by concentrating his energy on operating the car. In the navigation system for cars, the advancing direction of the car at an intersection is previously designated by the driver, information regarding driving straight or turning is projected by a projector which includes an LCD or a fluorescent indicator tube whenever the car approaches the intersection based on the information, the above projected light is projected on a half-mirror provided at the front windshield of the car and an imaginary image is reflected before the front glass.
