    Summary

    This study used electroencephalography (EEG) to measure stress during visual display terminal (VDT) work. Findings suggest EEG variations correlate with performance, offering insights into human-computer interaction and workplace stress.

    Area of Science:

    • Human-Computer Interaction
    • Neuroscience
    • Occupational Health

    Context:

    • Visual Display Terminals (VDTs) are crucial interfaces in modern computing.
    • Evaluating user stress and performance during VDT tasks is essential for optimizing work environments.
    • Understanding the physiological responses to VDT work can inform ergonomic and safety guidelines.

    Purpose:

    • To investigate the relationship between VDT work, stress levels, and cognitive performance.
    • To utilize electroencephalography (EEG) as a quantifiable index of stress during VDT operation.
    • To compare physiological responses during VDT tasks with traditional paper-based work.

    Summary:

    • EEG was recorded during a visual search test on VDTs and a comparable paper-based task.
    • A three-way analysis of variance examined EEG wave band data based on working time, head location, and age groups.
    • Results indicate a correlation between EEG variations and task performance, suggesting EEG as a valid stress indicator.

    Impact:

    • Provides objective physiological data on the impact of VDT use on cognitive load and stress.
    • Highlights the potential of EEG for monitoring worker well-being and performance in computer-intensive roles.
    • Informs the design of healthier and more productive human-computer interaction systems.
