Abstract
The RoboFlag system was designed as a testbed to study distributed
control of multiple vehicle teams with humans in the loop. This work
analyzed the RoboFlag version 2.0 interface to identify existing
issues with the users' Situational Awareness (SA). The existing
interface for RoboFlag was modified to create two new interfaces. The
first interface focused on improved usability, while the second
focused on improved Situation Awareness. A user evaluation was
conducted to determine if the new interfaces improved the users' SA
over the original interface. Twenty-four participants completed the
evaluation. This paper reports the design of the task environment,
the evaluation method, and the statistical analysis. The results
indicate that both new interfaces provide improved SA over the
RoboFlag version 2.0 interface.
