Zusammenfassung

In this paper we aim to test a prototype dry electrode headset during a parabolic flight in microgravity phases. We want to investigate, whether the EEG data measured with the same system during microgravity phases of a parabolic flight have the same quality as on Earth. Therefore, we conducted a study (3 operators) with an N-back task, which can be solved under both conditions. Each operator performed the experiment with the same dry electrode headset under microgravity as well as under Earth gravity to make the data comparable. The results show that it is possible to measure EEG data under microgravity with a prototype dry electrode headset. The data provide 87.5% of significant differences between workload conditions (p < 0.02) under microgravity and 75% of significant differences between workload conditions (p < 0.002) under Earth gravity, if the analysis pipeline is carried out in the same way. In conclusion, the results are promising and it is worth conducting a further study with more operators using dry electrode systems under microgravity.
