This paper aims to explore the design method and principals for interactive individual combat information visualization system. The operation and efficiency of existing individual combat information system are analyzed, an improved one which provides combat mission management, differentiated display according to the importance of information is proposed, users' awareness of combat situations is enhanced, their memory burden is reduced, and they are allowed to interact with terminals more efficiently to better meet their needs. This system is based on visual cognitive theory, and is designed from the perspectives of human-machine interaction, layout, and vision. The useability of the proposed system is verified by experiments. The results reveal that the proposed system significantly improves the efficiency of information transmission, and allows users to perform their mission more effectively, thus improving users' satisfaction.
