While seated in a vehicle mockup, drivers (6 young, 6 old) made same/different judgements of simultaneously shown pairs of slides (real intersections and navigation displays that could be for them). The navigation information was presented on either an instrument panel (IP) display or superimposed on the road scene, simulating a full-windshield, head-up display (HUD). Response times to full-windshield HUDs (1170 ms) were shorter than IP displays (1511 ms), a difference of about 20 %. HUD colour had no significant effect on response time, but displays aligned with the road scene produced times slightly faster than misaligned ones (34 ms difference). As reported previously, plan and aerial views were responded to faster than perspective views. Due to high error rates in some conditions, continued experimental evaluation of full-windshield HUDs is desired. The purpose of this research was to examine driver performance with a simulated full-windshield, head-up display (HUD) that might be used for navigation. Although such a device is not practical at the current time, it may be some day. To justify the engineering development of a full-windshield HUD, an assessment of the usability benefits (less the burden of costly product engineering) was desired. Specifically, this research was conducted to (1) identify the best possible navigation performance achievable, (2) examine the usability of a particular implementation of a navigation interface, and (3) determine the potential safety benefits of that interface.
