基于认知负荷的雷达任务编排系统交互设计研究

Research on Interaction Design of Observation Arrangement System Based on Cognitive Load

本文从交互设计要素入手,以降低用户的认知负荷水平、提高人机系统工作绩效为目的,对雷达任务编排系统界面的设计展开研究。以某雷达任务编排系统为研究载体,提出了交互设计策略和方法,并进行交互设计实践。最后通过NASA-TLX主观量表和任务绩效法对设计前后的系统分别进行对比测试。实验结果显示,在重新设计的任务编排系统中,被试的认知负荷明显低于原系统,证明了设计策略的有效性。

In order to reduce the cognitive load level of users and improve the performance of man-machine system, this paper studies the interface design of observation arrangement system from the interaction design elements. Taking an observation arrangement system as the research carrier, the strategy and method of interaction design are put forward and the interaction design practice is carried out. Finally, NASA-TLX scale and task performance method were used to compare and test the system before and after design. The experimental results showed that the cognitive load of the subjects in the redesigned observation arrangement system was significantly lower than that in the original system. It proves the effectiveness of information architecture design strategy.
