摘要
In the teamwork of nuclear power plants (NPPs), the maintenance of mutual awareness enables the operators to have an up-to-the-moment understanding of each other's work and makes the collaboration more efficient. Providing interface support for mutual awareness is proven to be an effective way to enhance the operators' mutual awareness in digital systems. What mutual awareness-relevant information to provide and how to present the information on the display are two questions worth studying. This research focused on the above two questions and provided a newly designed mutual awareness toolkit on the context of digital interfaces in NPPs. The usability of the designed toolkit was evaluated through a laboratory experiment. The influence of the mutual awareness toolkit on team performance and its interaction effect with task complexity was further examined under incident scenarios. The results showed that the designed mutual awareness toolkit improved the operators' mutual awareness, while it did not decrease their individual situation awareness (SA) or impose extra mental workloads. In team diagnosis tasks, the teams using the mutual awareness toolkit more thoroughly discussed the incident scenarios and identified more key points of the incidents. The diagnosis correctness, perhaps moderated by other factors besides mutual awareness, was not significantly improved.
