In order to evaluate the human-computer interaction efficiency of the command and control system more accurately,this article establishes an evaluation index system based respectively on the three elements of human-computer interaction,i.e.,command personnel,command and control system,and interaction equipment.The entropy weight method is combined with CRITIC to assign weights to each index,and the Fuzzy Comprehensive Evaluation (FCE) method is used to comprehensively evaluate two types of command and control systems.Finally,GOMS model and eye tracking technology are used to verify the evaluation method from the aspects of task completion efficiency and cognitive load of the commander,etc.The results indicate that this method has certain reference value and significance,which provides a scientific and convenient evaluation method for human-computer interaction effectiveness of the command and control system.
