Head-up displays and their automotive application: an overview of human factors issues affecting safety.
In response to the recent innovations to use head-up displays (HUDs) in vehicles, this paper discusses the relevant human factors issues arising from this display format and the potential safety implications. A review is made of the relevant HUD literature, primarily from the aviation field. The primary issues for automotive HUDs relevant to system performance and safety in the driving task involve interference from background scene complexity, system novelty, user perceptual style, cognitive disruption, and perceptual tunnelling. Basic research is necessary to investigate the extent of these issues as well as to resolve fundamental design specifications (e.g. HUD size, shape, placement, information content). It is suggested that the introduction of HUDs into vehicles be carefully considered. This will necessitate not only the reconsideration what constitutes an in-vehicle display, but also what constitutes the information to be conveyed.
