Abstract

In this study, we experimentally investigated the effects of the interaction between two individual systems, an automation system that conducts tasks and an alert system that monitors automation performance and alerts users to automation failures. The experimental results showed that when users used automation and alert systems together, when the alert system missed automation failures, the participants lowered their trust not only in the alert system but also in the automation system. It means that the participants confused trust in the automation system with that in the alert system. Moreover, when the participants highly trusted the automation system, they slowly responded to a true alert from the alert system. These results were discussed on the basis of the theory shown in previous studies.
