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.
INTRODUCTION
RoboFlag is a robotic team-based game similar to
"Capture the Flag" (RoboFlag, 2003). The teams rely on
a human operator to govern their play. The operators
specify plays that the robots then autonomously fulfill.
The system is designed to allow researchers to explore
basic and complex issues in several areas, including
