Physiological monitoring in Army simulators revealed that heart rate and skin responses are sensitive indicators of simulator sickness. These measures better detect sickness severity compared to other physiological signals.

Area of Science:

  • Aerospace Medicine
  • Human Factors Engineering
  • Physiological Monitoring

Background:

  • The Army's Crew Station Research and Development Facility (CSRDF) utilizes advanced rotorcraft simulators.
  • Simulator-induced sickness is a concern in training and research environments.
  • Objective physiological measures are needed to assess sickness severity.

Purpose of the Study:

  • To develop and validate physiological monitoring for Army rotorcraft simulators.
  • To assess the sensitivity of various physiological measures to simulator sickness.
  • To correlate physiological data with self-reported sickness severity.

Main Methods:

  • Development of a physiological monitoring system for the CSRDF.
  • Collection of preliminary physiological data during simulator studies.

  • Analysis of heart period, tachygastria, skin conductance, vagal tone, and gastric myoelectrical activity.
  • Comparison of physiological sensitivity with self-reported simulator sickness.

    • Main Results:

    • Heart period, tachygastria, and skin conductance level showed higher sensitivity to simulator sickness.
    • Vagal tone and normal myoelectrical gastric activity were less sensitive indicators.
    • Physiological measures demonstrated potential for objective sickness assessment.

    Conclusions:

    • Physiological monitoring can objectively quantify simulator sickness.
    • Specific physiological parameters like heart period and skin conductance are promising biomarkers.
    • This capability enhances the utility of Army simulators for research and training.
