摘要

对不确定性的理解,或者真实地理现象与用户对该现象的理解之间的差异,对于那些使用空间数据的人来说是必不可少的。从这个角度来看,地图符号可以用作提供有关不确定性水平的信息的工具。然而,以这种方式向用户传达不确定性可能是一项具有挑战性的任务。本文的主要目的是提出直观的符号来表示不确定性。他的目标是通过特别编译的点符号集的用户测试来实现的。强调的是所提出的符号的直观性和易于解释。符号是以用户为中心的眼球追踪实验的一部分,旨在评估所提出的解决方案的适用性。通过分析眼球追踪数据来确定受试者在阅读地图符号时的表现。这些分析包括对观察参数、用户偏好和认知度量的评估。在此基础上,推荐并讨论了最合适的点符号设计方法。

Intuitiveness of geospatial uncertainty visualizations: a user study on point symbols
Be understanding of uncertainty, or the difference between a real geographic phenomenon and the user’s understanding of that phenomenon, is essential for those who work with spatial data. From this perspective, map symbols can be used as a tool for providing information about the level of uncertainty. Nevertheless, communicating uncertainty to the user in this way can be a challenging task. Be main aim of the paper is to propose intuitive symbols to represent uncertainty. Bis goal is achieved by user testing of specially compiled point symbol sets. Emphasis is given to the intuitiveness and easy interpretation of proposed symbols. Symbols are part of a user-centered eye-tracking experiment designed to evaluate the suitability of the proposed solutions. Eye-tracking data is analyzed to determine the subject’s performance in reading the map symbols. Be analyses include the evaluation of observed parameters, user preferences, and cognitive metrics. Based on these, the most appropriate methods for designing point symbols are recommended and discussed.
