Techopedia explains Heads-Up Display (HUD)

Initially used in aeronautics engineering, HUD technology was designed to give pilots the ability to see aircraft specific data on an aircraft's windshield.

Today, HUD is applied in a variety of fields and areas, including:

  • Gaming gadgets
  • Assisting drivers in vehicles
  • Other three dimensional (3-D) display or augmented reality applications
HUD has three primary components: a video generating computer, projector and combiner. The video generating computer stores the information to be displayed and sends it to the projector unit, which projects the information to the glass screen. The combiner is responsible for combining the natural environment and background display with the computer generated display, allowing a user to view each simultaneously.
