Research on the Influence of Icon Shape Complexity and Composition on Visual Search Based on Military Geographic Intelligence System

This article discusses the influence of icon shape complexity and composition on icon search in military geographical intelligence system. We designed an experiment to explore the influence of icon shape complexity and composition on icon search efficiency in military geographic intelligence system (GIS). The reaction time and accuracy are used in the experiment to reflect people's search efficiency under different experimental conditions. The experimental results provide a scientific reference for the design of military GIS interface by analyzing the effect of different icon shapes and icon presentation on the visual search performance of military GIS interface. Through experiments, it is found that when the icon shape complexity level is the highest or the lowest, it shows poor search performance; when the complexity level is H3, it shows the best search performance; the icon composition does not affect the search performance of the icon on the map background. Significant, but when the complexity level is H2 and H4, there is interaction between different icon composition. This design will provide a reference for the design of GIS interface icons. The experimental results provide a scientific reference for the design of military GIS interface.
