In transportation and aerospace, more automation and autonomy are continuously added to systems. The ability of human operators to effectively monitor and interact with these systems, poses significant challenges. This research focuses on critical decisions that largely rely on the system capabilities but need to be validated and taken upon the operator responsibility. We investigate, in the context of UCAVs (Unmanned Combat Air Vehicle), how the communication strategy of the semi-autonomous systems modifies the operators' understanding of the situation and the final decision. A user-study has been performed in an immersive simulator with an ecological 30 minutes military scenario where the operator had to manage a full mission, including an unexpected fire decision. The experiment embraced the use of physiological measures (ECG, EDA) and an eye tracking setup. The paper reports results related to the decision-making performances and analyses of physiological parameters. It appears that the communication strategy does impact the situation awareness of the operator, the decision taken, and the evolution of the physiological parameters. |
