2.1.2 Heads Up Display (HUD) are transparent displays. They can be useful for aeroplanes, automobiles, computer games etc. The device will project information on a windshield such that the users do not need to look away from their field of view. An ordinary HUD contains a projector unit, combiner and a computer as its components. Projector Unit will project the image and the combiner will redirect the projected image such that we can see the field of view and the projected image at the same time. Computer is an interface between projector unit and data to be displayed.
