A growing number of aerospace human-machine system applications require real-time physiological monitoring of the human operator. These real-time measurements allow the system to estimate the operator’s cognitive states, which can drive the level of automation support. This concept is adopted in our Cognitive Human-Machine Interfaces and Interactions (CHMI2) framework. Accurate and reliable measurements from the physiological sensors are essential for the CHMI2 concept to work. The Heart Rate (HR) is one of the most commonly monitored physiological variables in aerospace applications. In this paper, we evaluate the suitability of a common wearable cardiac monitoring device to carry out real time HR measurements. The validity is evaluated by comparing the processed measurements from the wearable device to a clinical validated device. Contrary to most studies which only target physical activity for such characterisation, we investigate a terminal manoeuvring area traffic management activity, which is a very challenging aerospace task involving a significant number of time-critical human-machine interactions where high levels of cognitive workload are experienced. The results from the presented characterisation support the suitability of the cardiac monitoring sensor for the intended CHMI2 system application.
