Outline
The nuclear power display control system is a typical cross-screen interaction scenario in which the manipulator must accurately and rapidly monitor and respond to multiple sources of fault alarms, and the attentional capture effect plays a critical role. This study designed variables from the two dimensions of cross-screen interaction and fault alerts. In a single trial, variables such as the number of cross-screens, cross-screen orientation, the number of alerts, alert level, and alert location were set in random combinations. Eye-tracking technology and behavioral experiments were conducted to capture operators' visual attention behavior under different interaction conditions. The research reveals that an increase in the number of cross-screen displays adversely affects the attention capture effect, causing operators to frequently shift their perspectives to locate target stimuli and reducing task efficiency. As the number of alerts increases, there is a declining trend in the number and duration of fixations, indicating that excessive alert signals may lead to information overload and hinder operators' in-depth processing of individual alerts. High-level alerts effectively capture attention and facilitate rapid responses. In the future, considering the distribution of users' attention and task efficiency in cross-screen behavior scenarios, by optimizing the layout of monitoring screens and the fault alert system, improving alert design, and reducing the need for perspective transfer, the safety and reliability of alert detection task operations can be enhanced.
