  We present a user interface (UI) based on augmented reality (AR) with
head-mounted display (HMD) for improving situational awareness during critical
operation and improve human efficiency on operations. The UI displays
contextual information as well as accepts orders given from the headset to
control unmanned aerial vehicles (UAVs) for assisting the rescue team. We
established experiments where people had been put in a stressful situation and
are asked to resolve a complex mission using a headset and a computer.
Comparing both technologies, our results show that augmented reality has the
potential to be an important tool to help those involved in the emergency
situation.
