Instant messaging in military simulations can degrade operator performance and situation awareness (SA). Further research is needed to manage chat effectively and improve adaptive display designs for better human-in-the-loop control.

Area of Science:

  • Human-computer interaction
  • Military simulation and training
  • Cognitive performance

Background:

  • Instant messaging is a critical communication tool in network-centric warfare.
  • Real-time chat interfaces offer unobtrusive measurement of operator situation awareness (SA) and workload.
  • Existing military operations face challenges managing large volumes of chat information.

Purpose of the Study:

  • To examine human performance issues in supervisory control of the Navy's Tactical Tomahawk missile using a human-in-the-loop simulation.
  • To quantify the impact of instant messaging as a secondary task on operator SA and workload.
  • To investigate the degradation of mission performance due to instant messaging fixation.

Main Methods:

  • Development of a human-in-the-loop simulation test bed for missile control.

  • Real-time measurement of operator situation awareness and workload via an embedded instant messaging program.
  • Analysis of mission performance degradation and SA loss in subjects fixated on the secondary chat task.

    • Main Results:

    • Instant messaging as a secondary task led to fixation, degrading primary task performance (missile control).
    • Operator situation awareness (SA) was compromised due to distraction from the instant messaging interface.
    • This study is the first to quantify command and control performance degradation linked to instant messaging use.

    Conclusions:

    • Instant messaging interfaces, while valuable for communication, can negatively impact operator performance and SA in high-stakes tasks.
    • Managing information overload and mitigating fixation on chat interfaces are critical for effective military operations.
    • Further research into adaptive display designs is necessary to ameliorate problems associated with instant messaging in military command and control systems.
