The Development of a Head-up Display (HUD) App on the Android Mobile Operating System

Abstract

The head-up display (HUD) is a premium feature found mostly in expensive cars. The method how it works is really simple, some information has to be projected on the windscreen of the car, so the driver won’t have to look down on the gauges, and he can keep his eyes always on the road. A head-up display (HUD) is useful due to the fact that it can project the speed of the car on the windscreen and this way the driver can avoid speeding tickets. Also the projection on the windscreen it’s small and transparent, so it won’t bother the driver, which can watch the road, not the gauges. The projection method is straight forward, due to the fact that almost any object is reflected on a car’s windscreen, and a light up display, of a mobile phone, on low lighting conditions, it’s reflected even more. The goal of this work is to create a head-up display (HUD) using an Android mobile phone. This way this expensive feature for cars can be used in any car, by the use of a mobile phone only. The work presents the development process of an app, on a mobile phone, which can be used to project speed and optionally other informations on the windscreen of a car. The main concern of creating such an app is to figure out the mirroring of the mobile phone’s screen, to see an image which is not rotated, on the windscreen of a car.
