The company designed its prototype to project an image through a two-way mirror, so that information appears superimposed over the reflected road view. The device went on display at the Society for Information Display's Vehicles and Photons 2009 symposium held in Dearborn, Michigan.

Such a device could improve driving safety by allowing drivers to get critical information without having to look away from the road. Light Blue Optics also says that their technology works just as well on forward displays, such as a car windshield. Just don't expect to drive cars with the devices for at least several more years.
