The effect of font boldness, noise disturbance and time pressure on human error in the context of cloud change operation
通过模拟云变更业务流程，研究了字体加粗、噪声干扰和时间压力对操作员错误数、完成时间和工作负荷的影响，发现加粗仅在安静或低时间压力下减少错误，噪声增加错误，时间压力不影响错误数但增加主观负荷。
This study investigated the number of operator errors, task completion time, and workload of subjects at different levels by imposing conditions such as focused text boldness, noise disturbance, and time pressure to simulate a realistic cloud change business process in the laboratory. Results of the study showed that the text bolding of important content reduced the number of errors, whereas noise interference increased the number of errors. Text boldness only reduced the number of corrected errors, and noise interference only increased the number of uncorrected errors. Moreover, bolding was found to have different effects on the number of errors under different noise levels and time pressure levels, with text boldness significantly reducing the number of total errors only in quiet or low time pressure states. Time pressure had no effect on cloud change task error counts, but high time pressure resulted in higher subjective workload.
