This paper introduces a novel design for an automotive full-windshield Head-Up Display (HUD) interface which aims to improve the driver’s spatial awareness and response times under low visibility conditions. We have further designed and implemented a working prototype of a Human Machine Interface (HMI) to fulfil these requirements. Particular emphasis was placed on the prioritisation and effective presentation of information available through vehicular sensors, which would assist, without distracting, the driver in successfully navigating the vehicle under low visibility conditions. The proposed interface is based on minimalistic visual representations of real objects to offer a new form of interactive guidance for motorway environments. Overall, this paper discusses the design challenges of such a human-machine system, elaborates on the interface design philosophy and presents the outcome of our user trials that contrasted the use of our proposed HUD against a typical Head-Down Display (HDD).
