Paper Abstract

In applying a head-up display (HUD), originally developed for aircraft use, to automobiles, it is very important to analyze how it affects the driver's ability to recognize foreground objects and what kinds of advantages can be derived from its application. This paper describes the effects of reducing line of vision movement and recurring eye accommodation, as well as interference between complex HUD display patterns and foreground objects and the requirements for preventing such interference. Experiments were carried out under conditions determined in preliminary investigations using real vehicles in city driving situations. The results suggested that, so long as the brightness of the displayed objects is set properly, a HUD can be an effective automotive display system providing good recognizability of both displayed information and foreground objects.
