Dynamical analysis in real time: detecting perturbations to team communication.

Area of Science:

• Dynamical systems theory
• Real-time data analysis
• Human-computer interaction

Background:

• Traditional dynamical systems methods analyze data post-collection.
• Sudden perturbations during ongoing processes can lead to negative outcomes.
• Real-time application of dynamical analysis is needed for timely intervention.

Purpose of the Study:

• To develop and demonstrate a real-time dynamical analysis method for detecting perturbations in team communication.
• To assess the method's efficacy in a simulated Uninhabited Air Vehicle (UAV) reconnaissance mission.

Main Methods:

• Real-time dynamical analysis by updating estimates across multiple window sizes.
• Calculation of the largest Lyapunov exponent to measure dynamical stability.
• Application to a simulated three-person UAV command-and-control team communication.

Main Results:

• The real-time dynamical method successfully detected unexpected perturbations in team communication as they occurred.
• The largest Lyapunov exponent served as an effective indicator of dynamical instability caused by the perturbation.

Conclusions:

• Real-time dynamical analysis offers a viable approach for detecting critical events during dynamic processes.
• This method has potential applications for real-time intervention in complex team operations.
• The technique's generalizability to physiological and motor coordination dynamics is considered.
