The Expanding Vision of Head-Up Displays: HUDs for Cars at Display Week 2017

摘要

In the automotive space, head-up displays ! (HUDs) allow drivers to see information such as speedometer, tachometer, and navigation system data without having to look away from the road while driving. In a conventional windscreen HUD system, this information can be projected from a system mounted in the dash onto a windshield film that provides the appearance of the information floating outside the vehicle. Next-generation windscreen HUDs called AR (augmented-reality) HUDs will project images on the street and in the environment as we drive. These images will go beyond a simple arrow indicating an upcoming turn; they will entail a series of arrows superimposed on the street and in the lane up to the turn point as we approach. This functionality requires a dramatic increase in the field of view and optics components in order to work in a realistic and reliable fashion.
