复杂信息系统界面可用性指标体系研究

On the Usability Evaluation Index System of Complex Information System Interface

随着复杂信息系统在军事领域和民用领域的广泛应用及不断发展,人们对复杂信息系统显示界面的设计有了更高层面的要求。通过可用性评估指导复杂信息系统界面设计改良,降低系统复杂性带给用户的工作认知负荷,提高用户绩效成为亟待解决的问题。针对复杂信息系统界面进行了研究,从界面特征、任务特征、认知特征进行了分析,提出了界面复杂性的影响因素,构建了复杂度评估指标体系,采用层次分析法针对界面的复杂性的指标权重进行了研究,并根据构建的复杂度模型提出了相应的可用性指标体系。

With the rapid development and extensive use of complex information system on both military and civil field,design of the display interface of complex information system needs to be improved to a higher level.The usability evaluation can be used to guide the improvement of the interface design of complex information system,which can reduce the workload of users induced by the complexity of system,and also improve the performance of users.This has already become a problem demanding prompt solution.This paper researched on the complex information system interface and analyzed from the features of interface,task and cognition,after which,the influence factors of interface complexity were put forward,the index system of complexity evaluation was constructed and the index weight of the complexity of interface was studied by AHP,and in the end,the corresponding usability index system was put forward according to the complexity model.
