核电厂监控显示界面中警示线路信息突显研究

Research on information highlighting of warning circuit in monitoring display interface of nuclear power plant

为提高核电厂操作员对监控显示界面信息的视觉搜索绩效,以界面中警示线路为研究对象,以信息突显方式作为变量,通过试验1研究弹窗对警示线路的遮掩问题,通过试验2研究警示线路突显方式的差异以及不同显示位置对用户视觉搜索绩效的影响。结果表明:弹窗透明度设置为35%时,弹窗下的警示信息可以被有效捕获;在弹窗透明度降低的情况下,用红色相框突显弹窗上的信息,被试对弹窗上信息的搜索绩效不会降低。原界面的警示线路以单一的红色突显,被试的搜索效率及正确率随着线路复杂程度的上升而明显降低;对警示线路使用层次化的明度编码,可显著提高视觉搜索绩效。对核电厂监控界面中警示线路的突显优化能够有效提高操作员视觉搜索绩效。

In order to improve the plant operators to monitor display the visual search performance of information,taking the warning lines in the interface as the research object,the way to highlight information as variables,experiment 1 studied the pop-up window to the lee of the warning line problem,test 2 studied nuclear power warning line highlights the different ways and warning lines show the location of the influence of different of user's visual search performance.The test results show that when the popover transparency is set to 35%,the warning information under the popover can be captured effectively.When the transparency of the pop-up window is reduced,the search performance of the information on the pop-up window will not be reduced if the information on the pop-up window is highlighted by a red frame.The warning lines in the original interface were highlighted with a single red color,and the search efficiency and accuracy of the subjects decreased significantly with the increase of the complexity of the lines.Using hierarchical lightness coding for warning lines can significantly improve visual search performance.Highlighting and optimizing warning lines in the monitoring interface of nuclear power plant can effectively improve operator visual search performance.
