Summary
A human operator in a human-machine system is exposed to multiple stresses in his or her job. If the workload exceeds a certain point, human performance breaks down (Wickens, 2002). This can have significant consequences for missions. Ways to address this problem are 1) Inform the operator about his workload, 2) reduce the workload, or 3) provide support through automation. To do this, it is important to know the operator's current workload. It is uncertain whether individuals are always able to recognise and communicate their own performance limits. Since it is scientifically established that physiological parameters correlate with stress reactions, it makes sense to use them to monitor the current workload (Wierwille & Eggemeier, 1993). It is important to recognise the individual reaction to workload and stress and also to take psychological factors into account. Heart rate and heart rate variability (HRV) have been investigated in some workload and stress studies in the past. For example, one parameter that is sensitive to changes in stress and workload is heart rate (Hidalgo-Muñoz et al., 2018). In the review by Tao et al. 2019, it was described that significant differences in mental workload could be detected in studies related to aviation. Thereby, 57% of the studies (12 out of 21 studies) showed significant effects in heart rate and e.g. 5 out of 5 studies in HF/LF ratio and 6 out of 7 studies in SDNN. The aim of the project is to identify sensitive physiological parameters from the ECG signal from which different degrees of stress can be recognised (heart rate, HRV parameters). Special attention will be paid to which psychological variables have an effect on this parameter. At the end of the project, a combined psycho-physiological instrument should be developed that is sensitive to individual reaction patterns and can be used in further studies on workload in an aviation context. This instrument should be designed in such a way (small, mobile, not disturbing, not time-consuming) that it can also be used by pilots in their daily work.
