“…In NPPs of new generation like AP 1000, digital displays are extensively used. Such transform on the one hand caters to the trend of technology advance, improving the safety and reliability of the systems; on the other hand, it brings high information burden, tedious interface management tasks, and other new problems (Kim & Seong, 2009). For this reason, designing a good digital interface in MCRs, which meets the task demand and the physical and psychological characteristics of operators, is of necessity.…”

The increasing use of digitalized displays in the instrumentation & control systems of nuclear power plants has brought new issues related to human-computer interaction, especially under emergency circumstances that are known to be very stressful. This paper studies how interfaces with different information organization (functional layout vs. process layout) influence human-computer interaction behaviors as emergency occurs in terms of search efficiency, difficulty of information abstraction, and workload by using the eye tracking technique on a simulated platform. The result shows that the average blink rate and average blink numbers at the two levels of information organization were different significantly. This may indicate that the functional design was superior to the process design in user workload. The results did not prove the superiority of the functional interface design to the process one in search efficiency and difficulty of information abstraction, since no significant difference was found in the number of fixations and fixations duration mean values.
