信息叠加混杂对地面作战决策的影响OA

Information overlay is a key display feature in ground combat vehicle-mounted systems,but the specific impact of the resulting display clutter factors on decision making behavior remains unclear.This study employed a simulated ground combat decision making task and a three-factor within-subjects repeated measurement experiment design to evaluate the effects of background clutter,the proportion of irrelevant information,and the types of near and far domain information overlay clutter on decision performance,decision confidence,and perception of clutter.The results of analysis of variance and correlation analysis indicate that near-domain overlay clutter and removed backgrounds result in longer decision time.The interactive effect of a high proportion of irrelevant information and high background clutter reduces decision accuracy.The decline in decision confidence is related to the increase in overall perception of clutter.Prolonged decision time is associated with the increase of workloads,insignificance of targets,enhanced information redundancy and density,and increased perception of overall clutter.These conclusions provide guidance for the design of information overlays in ground combat decision-making scenarios.
