Research On Situation Command Interface Color Matching Based On ERP Experiment

Under the condition of information warfare,with the increasing mobility of combat units,command organs put forward higher requirements for the accuracy and real-time of battlefield situational awareness information.Situational command simulation system exists to help solve the evaluation of command system and other problems.This paper is based on the situation command simulation system.Firstly,the interface of situation command system and simulation system in different countries is studied and analyzed,and the basic functional modules of situation command simulation system at home and abroad are integrated and summarized.According to the division of these functional modules and the period of command operators using these functional modules,the situation command interface of this paper is divided into two parts,one is situation command interface.The other part is the background color of situation map and navigation bar.Subsequently,according to the visual dimension direction of situation command interface,this paper divides situation command interface into color dimension,text dimension and layout dimension,and elaborates the importance of color matching research in situation command interface.The research of color matching is based on the direction of color psychology,man-machine loop and visual perception hierarchy.In the electroencephalogram experiment of situation command interface map and enemy-foe target recognition,the color of the target is divided into three-dimensional Munsell color in visual distance.In the research of background color of navigation bar,it is the same as the previous experiment.The selection of background color is based on the color system of Munsell color stereo.Then,ERP experiments were carried out on the map of situation command interface and the search task of enemy-foe target recognition.The response time and accuracy of subjects under different target colors were analyzed,and the amplitude and latency of P300 generated in the experiment were analyzed.Then,EEG experiments were carried out on the situation map of situation command interface and background color of navigation bar.The Oddball experimental paradigm was used to analyze the response time and accuracy of the subjects,as well as the amplitude and latency of the P300 generated in the experiment.The main experimental conclusions are as follows:(1)In the visual search experiments of situation maps and enemy-or-foe targets,in the color matching of several different targets,the colors with higher brightness and purity have shorter latency period,and the larger amplitude takes up more time and attention space.(2)The Ooddball paradigm was used in the ERP experiments of situation maps and navigation bar background colors.The amplitudes and latency of P300 caused by three background colors were different.The results showed that blue with lower saturation was more advantageous in serach task.
