Interface Design for Human-Machine Collaborations in Drone Management

Unmanned aerial vehicles (UAVs) operate with large degrees of autonomy when executing tasks from a ground-based controller. In this work, we design an (immersive) interface for drone management. Our interface supports operators in mission execution of one or several (automated) UAVs within a fleet. This allows operators to assign tasks to UAVs, while safe operations are ensured through in-flight conflict detection and prevention. Our interface fulfills both functional (e.g., reliability) and non-functional requirements (e.g., perceived cognitive load during use). A key design challenge is the latency in information exchanges, which introduces information asymmetries between the humans and UAVs. We then validate the effectiveness of our interface design across several experiments. We find that our design reduces the perceived cognitive load and improves task performance. Altogether, this work has implications for designing interfaces in human-machine collaboration, so humans can effectively control, interact, or collaborate with automated machines, such as UAVs.
