【摘要】 在人机交互界面中,信息要素的呈现方式影响了用户的决策能力。这种能力不仅依赖于对任务决策领域相关信息的理解,还依赖于信息本身的属性,即元信息。文章阐明了元信息的概念、类型和元信息视觉显示设计对任务决策的影响,并以不确定性为例对元信息的视觉显示设计方法进行了总结比较。最后针对台风扩散范围不确定性进行了多种不同方法的元信息可视设计,通过实验得出利于用户决策的优化设计方法。更多还原

【Abstract】 In the human-computer interaction interface, the presentation of information elements influence the decision-making ability of users. This ability depends not only on the understanding of the relevant information in the task decision domain, but also on the quali?ers of that information, which we will refer to as meta-information. This paper clari?es the concept, types of meta-information, and the in?uence of visual representations of meta-information on task decision-making,and then taking uncertainty as an example, summarizes and compares specific meta-information visualization methods. Finally, the visual representations of metainformation of different methods is carried out for the uncertainty of typhoon diffusion range, and the optimal design method for user decision-making is obtained through experiments.更多还原
