As the population of Americans 65 years and older is projected to double in the next twenty years, General Motors responds to the need for more elderly-friendly vehicles by developing a new windshield technology that will help drivers with vision problems see more clearly. The technology is still in the research stage but is expected to be very useful in the near future.

Although it will not improve the driver’s vision, it will make objects that could otherwise go unnoticed by aging eyes stand out more. The high-tech windshield will feature a combination of lasers, infrared sensors and a camera to enhance the road view. For instance, during foggy days, a laser projects a blue line into the windshield that follows the edge of the road.

Infrared sensors will also detect objects, such as a person or an animal, in the driver’s path during night time driving; it will project an outline of the object on the windshield to highlight its location.

Other devices track the driver’s head and eye movement so that the image on the windshield isn’t skewed. Aside from GM, only Chrysler is currently working on similar windshield technology.
