Gender Characteristics on Gaze Movement in Situation Awareness

In large systems, such as nuclear power plants, the operator’s situation awareness is vital to the system’s safety. Since gaze movement is closely related to situation awareness, various studies have evaluated it through gaze movement. The number of female workers is increasing even in large systems...

Shannon entropy, dwell time entropy, and heat map entropy did not show a significant difference between men and women, but Markov entropy was found to be significantly higher in women. In conclusion, there was no significant difference between men and women in awareness of accident situations.
