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 usability
issues. The existing interface 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 both new interfaces improved the system
usability over the original interface. Twenty-four participants
completed the evaluation. This paper reports the design
considerations, the experimental apparatus, and the usability based
statistical analysis. The results indicate that both new interfaces
provide improved usability over the RoboFlag version 2.0 interface.
