Abstract
Because the pathway display shares motion with outside elements, it was hypothesized that a pathway HUD may enhance tracking and detection when compared to its head-down counterpart. In two experiments, performance with a HUD was compared to performance head-down, and pilots performed a series of simulated tasks in low and high visibility. The results indicate that while detection of events is generally enhanced by the HUD, tracking is influenced by the level of available visual detail when the HUD is used. When little visual detail is visible, tracking performance is equivalent between the two display locations, while the presence of elements of interest (such as airport features) was found to degrade tracking with the HUD. However, when conformal elements are present, tracking is facilitated with the HUD over the head-down location. The results are discussed in terms of space- and object-based models of attention, and future work is defined to further examine how pilots allocate their attention when using virtually conformal displays.
