基于用户认知的态势可视化设计研究

Visualization Design Research Based on User Cognition

针对态势信息层级复杂、显示不清晰、重点不突出等问题,论文基于用户认知开展态势可视化设计研究。首先,分析了用户认知特性及态势可视化设计流程,在此基础上,从信息数量、关系、维度、主次等多层面,提出了基于用户认知的态势可视化设计策略,包括分层分级、关联聚合、时空多维、焦点推送等;然后,选取密集多目标、重点关注目标两个典型态势场景,开展可视化设计策略应用。为态势显示设计提供理论和实践参考,有效降低用户认知负荷,增强态势感知和人机工效,带来更加直观友好的用户体验。

In order to solve the problems such as complex structure, unclear display and low emphasis of situation information, situation visualization design research is carried out based on user cognition. Firstly, user cognition characteristics and situation visualization process are analyzed. And the situation visualization design strategy based on user cognition is proposed from the perspectives of quantity, relationship, dimension, primary and secondary, including hierarchical classification, association aggregation, multidimensional spatiotemporal, focus push, etc. Besides, taking intensive multi-target and key target typical situation scenarios, this paper carries out visual design application practice. That provides a theoretical and practical reference for situation display design, and effectively reduces user cognitive load and enhances situation awareness and human-computer efficiency, resulting in more intuitive and friendly user experience.
