ABSTRACT
Our goal is to improve the design of human-
Unmanned Aerial Vehicle (UAV) interaction so operators can
have better situation awareness (SA) of conditions pertaining
to the UAVs. We developed a UAV interaction design
approach that uses pre-loaded terrain data to augment
real-time video data sensed by the UAVs. We hypothesized
that augmentation of the video in this manner would provide
better SA than a video stream alone. To test the hypothesis,
we performed a counterbalanced within-subjects experiment
in which the independent variable was video presentation
approach. Our results show an increase in comprehension of
3D spatial relationships between the UAV and points on the
earth when experiment participants were given an
augmented video presentation, as evidenced by a statistically
significant difference in participants' mapping accuracy. We
believe our results will generalize to situations beyond UAVs
to those situations in which people must monitor and
comprehend real-time, map-based information.
