Enhancing RoboFlag Users' Situational Awareness

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.
