This paper introduces a novel automotive full-windshield Head-Up Display (HUD) interface, which aims to improve driver’s spatial awareness and response times under low visibility conditions. In order to evaluate the effectiveness of the proposed HUD system, a multidiscipline and multinational team of researchers built the driving simulator presented further on. Due to time and cost constrains this simulator was assembled from off-the-shelf components and was based on an open source code. This paper will discuss the HUD function, present the challenging construction process of the simulator and provide an analytical overview of the two accident scenarios. The evaluation outcomes of forty user tests conducted using this custom-built driving simulator will be demonstrated and the conclusions of this study will be discussed.
