Subjective Mental Workload
本文综述了物理、认知、手动控制和时间压力任务与操作员主观负荷之间的关系，指出了关键任务变量和未来研究方向，对设计用户友好系统有参考价值。
Subjective workload is of increasing importance in user-machine systems, as the role of the human operator becomes less to control and more to monitor complex systems. This paper reviews the relationship between physical, cognitive, manual-control, and time-stress tasks and the subjective load experienced by an operator. The more important task variables are suggested, as are areas requiring research.
