Abstract
In a Car driving, it is known to be dangerous for the driver to read heads down display panels. In a PC-car or Networking Car, it is impossible for the driver to look down on the computer screen and read text web browser while he is driving on a high intensity road. In the "Car Heads Up Display"
invention, Web browser are projected onto the windshield with co-polarized lens that is fixed on the roof inside a car. The beam of co-polarized light reveals a co-polarized image on the windshield. The driver wear a pair of co-polarized glass. The direction of polarized light of the two lens are perpendicular to each other. The polarized direction of light that is projected onto the windshield is parallel to the right lens. As a result, the picture that is projected onto the windshield is visible only to the right eye while be invisible to the left eye. Function of the left eye is to see the road condition only, the right eye is to see both the road condition and the image that is projected on the windshield. With this task allocation between the two eyes by co-polarized beam of light, I reached two features:
1. Keep the valuable windshield totally transparent which is very important for the driver to drive safely.
2. No matter how complex the two dimentional co-polarized picture that is projected onto the windshield is, the driver won't feel hard to see the road condition.
Challenge:
A totally transparent windshield is valuable for driving safely, a Heads Up Display which enables both totally transparent windshield and images for the driver to check vehicular functions and browse Internet.

Description
Specification ~ This invention relates to project the co-polarized beam of light onto the windshield by fixing a co-polarized lens on the roof between the driver's seat and second driver's seat inside a car.
~ This invention relates to use co-polarized tool to reach the goal of safety Heads up display to the driver while he is driving on high intensity road.
~ This invention relates to realize Heads up display the Internet on the windshield.
~ This invention relates to separate the two eyes function with aid of human factors analysis.
~ This invention relates to automatically adjust the lightness in a car in order to delete the reflection on the windshield.
~ This invention relates to use co-polarized tool to reach the goal of safety Heads up display to the driver while he is driving on high intensity road.
~ This invention relates to realize Heads up display the Internet on the windshield.
~ This invention relates to separate the two eyes function with aid of human factors analysis.
~ This invention relates to automatically adjust the lightness in a car in order to delete the reflection on the windshield.
2. The previously known Heads Up Display could be classified in two ways:
( 1 ) A micro-heads-up display (HUD) that is worn like conventional eyeglasses. It uses a miniature optical system that presents an image at virtual infinity wherever the wearer looks. HUD of this type is, however, dangerous for the driver to wear because both eyes of the driver will be hold back by images and the driver have to distinguish three dimentional road conditions ahead and the images revealed by the glass.
~ This situation is specially unsafe on high intensity road. For example: It is hard for a person to see through a pair of "dirty" lenses. The more complex of images revealed by this type of HUD is, the more "dirty" the glass will be for the driver.
~ For night driving, the images revealed by this type of HUD is bright while the condition out of the car is dark. Under this circumstance, it is almost impossible for the driver to see the road condition.
(2) A heads up display that projects normal light beam onto the windshield (not co-polarized)---similar to the display used by jet fighter pilots to navigate their destination or to check the vehicle functions without taking their eyes off the road. HUD of this type is useful for pilots because environment out of the jet fighter is clouds and other jet fighters which is detectable by radar. In a car, however, it is dangerous to use too. In front of the eyes of the driver is high intensity road condition and objects in all shapes and colors and motions.
~ The more complex image on the windshield is, the more dangerous it is for driving. To project images on the windshield and be visible to both eyes is to add an obstacle layer in front of the driver. It damages the valuable resource of totally transparent and "clean" windshield.
Especially, at night driving, the images on the windshield could be like a mirror which make the darker road condition invisible to the driver.
~ They are not applicable in a car because they are unsafe for the driver to drive both at high density road or at night. As we all know, safe driving is the first rank task for the driver.

3. I have found that these disadvantages may be overcome by ( 1 ) Separating functions of two eyes of the driver.
(2) Fixing a co-polarized projecting lens on the roof between the driver seat and second driver seat in the car.
(3) Wearing a pair of co-polarized glass. The left eye can see road condition only while the right eye can see both the road condition and images on the windshield.
(2) Fixing a co-polarized projecting lens on the roof between the driver seat and second driver seat in the car.
(3) Wearing a pair of co-polarized glass. The left eye can see road condition only while the right eye can see both the road condition and images on the windshield.
(4) Letting the left eye see three dimentional road conditions while the right eye see two dimentional images.
(5) Connecting Internet to the projecting lens on the roof, the driver could do web browsing while driving.
(6) Automatically adjust the lightness in a car by installing silicon control switch together with a light sensor to detect lightness outside a car.
