Display of HUD Warnings to Drivers: Determining an Optimal Location

摘要

To design automotive head up displays (HUD), the extent to which HUDs interfere211u001ewith detection of elements of the road scene (other vehicles, edge markings, 211u001esigns, etc.) as a function of HUD location needs to be determined. In this 211u001eexperiment, 24 subjects sat in a driving simulator and watched a videotape of a 211u001ereal road. To encourage them to scan the road as they would while actively 211u001edriving, subjects pressed a key whenever they detected predetermined events in 211u001ethe road scene (passing cars, tail lights of a leading vehicle, road signs on the 211u001eright edge of the road). In addition, subjects pressed a key when an amber-211u001ecolored warning triangle appeared on the HUD at one of 15 locations.
