This project developed a GUI for the control of Unmanned Autonomous Vehicles (UAVs). As UAV missions become more sophisticated, the effects of deviations from these missions become more difficult to resolve. Human operators need tools to help them quickly and robustly determine why a UAV has made the decisions it has made, as well as the effects of those decisions on the UAV’s mission. This project developed innovative graphical user interface techniques solve these problems. These techniques were used to extend an existing UAV GUI and help operators come to terms with the obstacles presented by increasingly sophisticated autonomous vehicles.
