In this contribution we compare UAV delegation methods from a fighter-jet cockpit. Recent research approaches to UAV mission management have mainly been using touchscreen interactions and little research has systematically analyzed different input methods to delegate tasks. In this article, we present three UAV delegation methods that use touchscreen interactions, voice control, and a combination of eye-tracking and HOTAS buttons. The presented methods were integrated in a fighter-jet simulator and evaluated with ten participants. The performance of participants varied for different combinations of delegation method and task load. Touchscreen interaction was fastest on average, followed by voice interaction. The number of errors for each combination was only slightly different. When participants could select a method to use, they predominantly used voice interaction, followed by eye-tracking. The subjects showed the behavior of using eye-tracking method and switching to another method when it did not work as desired.
