The failure to respond to warnings can have fatal consequences, however, it is a common occurrence for even professional monitoring staff to overlook the warnings. This study developed a set of warning notification designs for remote emergency response and assessed their effectiveness by analyzing the performance and risk perception of monitoring staff through simulation experiments. Sixty participants of safety professionals (42 males and 18 females, Mean age = 28.71) participated in a within-subjects experiment, evaluating warnings with different design features and deciding whether to response. During the experiments, reaction time and task success rate were recorded for each warning task, and subjective scales were used to measure risk perception and response efficacy. The results indicate the positive effect of risk perception on enhancing performance, and demonstrate the impact of warning design features on shaping risk perception and response efficacy. Especially, the roles of warning icon and risk explicitness are emphasized. In addition, situation awareness and mental workload are proved to have positive impact on risk perception, while visual fatigue plays the opposite role. The findings demonstrate the effectiveness of enhancing risk perception and performance of safety monitors by controlling warning design features, contributing to the design of more effective emergency warning interface.
然而，未能对警告做出反应可能会带来致命后果，即使是专业的监测人员也常常会忽略这些警告。本研究针对远程应急响应开发了一套警告通知设计，并通过模拟实验分析监测人员的表现和风险感知来评估其有效性。60名安全专业人员（42名男性和18名女性，平均年龄 = 28.71岁）参与了一项受试者内实验，评估具有不同设计特征的警告并决定是否做出反应。在实验过程中，记录每个警告任务的反应时间和任务成功率，并使用主观量表来衡量风险感知和反应效能。结果表明风险感知对提高表现有积极作用，并证明了警告设计特征对塑造风险感知和反应效能的影响。特别是，强调了警告图标和风险明确性的作用。此外，事实证明态势感知和心理负荷对风险感知有积极影响，而视觉疲劳则起到相反的作用。研究结果表明，通过控制警告设计特征可以提高安全监测人员的风险感知和表现，这有助于设计更有效的应急警告界面。
