Human–Machine Interface Optimization Design Based on Ecological Interface Design (EID) Theory

With the development and application of digital technology, the human–machine interface of the console has been widely used with the computer as the core of the digital display control interface. The paper analyzes the effect of the application of EID theory in human–machine interface (HMI) in the nuclear power plant based on the actual HMI examples in the nuclear power plant. The analysis shows that EID has important application value in HMI design of the nuclear power plant, and the application of EID theory in the nuclear power plant will better organize the display information and improve operator’s ability to solve problems when encountering unanticipated events.
