    Operators performing complex tracking tasks experienced less psychic strain within a defined

    Area of Science:

    • Human-computer interaction
    • Ergonomics
    • Psychophysiology

    Background:

    • Operator performance in ergatic systems is influenced by psychic strain.
    • Understanding the limits of human performance is crucial for system design.

    Purpose of the Study:

    • To objectively evaluate the psychic strain experienced by operators during multiparameter compensatory tracking.
    • To identify the 'zone of functional comfort' for optimal control parameters.

    Main Methods:

    • Six operators performed multiparameter compensatory tracking of a moving object.
    • Psychic strain was objectively evaluated to identify parameter zones.

    Main Results:

    • A 'zone of functional comfort' was identified, requiring minimal psychophysiological cost.

  • Control outside this zone led to information overload or increased failure risk.
  • Five operators showed significant psychic strain aggravation when operating outside the comfort zone.

    • Conclusions:

    • Identifying the zone of functional comfort is key to optimizing operator performance.
    • Data display device design should incorporate this zone to enhance ergatic systems.
