How Head-up Displays Work

Author's Note

As I researched head-up displays I wondered if having all this information on our windshields is too much for us to handle. But as I saw the systems that are in development, I began to understand how HUDs will someday allow all of us to become better drivers. It can be available when we need it and we can turn it off when we don't want it.

Most of us are accustomed to having information at our fingertips all day long, so it makes sense to bring that same idea into our cars in more ways than just for music or entertainment. If HUD systems continue to develop at the rate they are right now, it won't be long before we're able to reduce accidents, assist drivers with vision impairments and see our surroundings a little clearer.
