Abstract: Teamwork efficiency and safety are inextricably linked. The capability of having online insights and access to objective information regarding cognitive and emotional aspects of the team members using neurophysiological measures (brain activity, skin conductance, heart rate) will endow a tool which can support Instructors during the assessment and management of teams. Such neurophysiological measures can be seen as the physical interface that will enable for gathering insights about all the aspects relating to Human Factors (HFs) of the operators. The study aimed at developing and validating a methodology able to objectively measure the teamwork dynamics and efficiency. This objective has been performed in a real surgery-related context. A data-driven approach based on machine - learning (ML) and multivariate autoregressive (MVAR) models has been employed to develop the Neurometrics - based teamwork model. Such a model considered the co-variations both within each HF (e.g., Low vs High Stress) and between different HFs (e.g., Attention vs Workload) to consider their simultaneous coexistence. The results of this preliminary study demonstrated that it is possible to quantify the teamwork of operators while dealing with real tasks and endow additional information for a more accurate teams assessment and management.
