Automated aids are engineered to support operators’ decision-making in complex and task-saturated environments, alerting them of system status and critical incidents. However, even the most advanced technologies are susceptible to failure. Monitoring imperfect automated systems poses unique challenges related to operator attention and workload. This study empirically examined the effect of unreliable automation on monitoring performance and responses to auditory stimuli in a multi-tasking environment. Participants completed an experimental trial consisting of four flight-related tasks while monitoring for automation failures at one of three levels of automation reliability. Participants in a high reliability condition responded more quickly and frequently to auditory messages. No performance differences were found in system monitoring performance between reliability conditions. These results are relevant to the design of automated system and delivery of automated alerts, and they have implications for operator attention allocation strategies in multi-tasking environments.

自动化可靠性对多任务环境中错误检测和注意听觉刺激的影响
自动化辅助设备旨在支持操作员在复杂且任务饱和的环境中做出决策,并向他们发出系统状态和严重事件的警报。但是,即使是最先进的技术也容易发生故障。监视不完善的自动化系统提出了与操作员的注意力和工作量相关的独特挑战。这项研究从经验上检验了不可靠的自动化对多任务环境中的性能和对听觉刺激的反应的影响。参与者完成了一项由四项与飞行有关的任务组成的实验性试验,同时以自动化可靠性的三个级别之一监视自动化故障。高可靠性条件下的参与者对听觉消息的反应更快,更频繁。在可靠性条件之间的系统监视性能中未发现性能差异。这些结果与自动化系统的设计和自动化警报的发送有关,并且对多任务环境中的操作员注意力分配策略有影响。
