This paper considers the impact of working with computer-based systems in terms of mental workload and the well-being of operators. In particular, the paper focuses on issues of controllability in human-computer systems as they relate to operator stress. Through the adoption of a state control model of stress regulation, it becomes apparent that while general usability criteria are necessary for the design of controllable systems, they may not be sufficient to guarantee controllability. The implications for research and system design are discussed, with reference to the assessment of operator workload, controllability and stress. A methodology for assessing computer stress is described, based on the analysis of stressful computer-related episodes and their accompanying affective and cognitive states. This technique allows the relationship between workload and controllability to be studied in particular computer work environments, in relation to individual work goals and coping strategies.
本文从心理负荷和操作员福祉的角度考虑使用基于计算机的系统所产生的影响。具体而言，本文关注人机系统中的可控性问题，因为它们与操作员压力相关。通过采用压力调节的状态控制模型，可以明显看出，虽然通用可用性标准对于可控系统的设计是必要的，但它们可能不足以保证可控性。本文结合操作员工作量、可控性和压力的评估，讨论了对研究和系统设计的影响。描述了一种基于对与计算机相关的压力事件及其伴随的情感和认知状态的分析来评估计算机压力的方法。该技术能够在特定的计算机工作环境中，结合个人工作目标和应对策略，研究工作量与可控性之间的关系。
