Abstract
The primary goal of this research was to compare the
performance in localization of stationary targets during a
simulated extra-vehicular exploration of a planetary surface.
Three different types of displays were tested for aiding
orientation and localization: a 3D spatial auditory display, a 2D
North-up visual map, and the combination of the two in a
bimodal display. Localization performance was compared
under four different environmental conditions combining high
and low levels of visibility and ambiguity. In a separate
experiment using a similar protocol, the impact of visual
workload on performance was also investigated contrasting
high (Dual-Task paradigm) and low workload (Single
Orientation task). A synergistic presentation of the visual and
auditory information (bimodal display) lead to a significant
improvement in performance (higher percent correct orientation
and localization, shorter decision and localization times)
compared to either unimodal condition, in particular when the
visual environmental conditions were degraded. Preliminary
data using the dual-task paradigm suggest that the performance
with displays utilizing auditory cues was less affected by the
extra demands of additional visual workload than a visual-only
display.
