摘要: 我们进行了一项眼动跟踪研究,以调查不同任务下对配有文本修饰的叙事式可视化结果的观察方式。研究的输入是带有注释、题注、标签和描述文字的数据可视化结果,。 我们考虑在查看这些类型的可视化图时三种常见的查看任务: (1)简单观察,(2)积极搜索以回答某个问题,(3)对图上信息进行记忆以备后用。总体目标是在感知层面上理解不同的任务是否影响以及如何影响可视化结果的观察方式。通过分析收集的凝视数据和对扫描路径进行高级的语义分析,可以发现凝视行为存在不同的模式: 简单的观察和信息记忆对应相似的观察策略,而积极搜索的方式则迥然不同,它们都与用户所关注的可视化结果的领域以及与修饰文字互动的频率相关。我们讨论了在不同应用场合中观察配有文字修饰的可视化结果的研究结果。

Abstract: We conduct an eye tracking study to investigate perception text-embellished narrative visualizations under different task conditions. Study stimuli are data visualizations embellished with text-based elements: annotations, captions, labels, and descriptive text. We consider three common viewing tasks that occur when these types of graphics are viewed: (1) simple observation, (2) active search to answer a query, and (3) information memorization for later recall. The overarching goal is to understand, at a perceptual level, if and how task affects how these visualizations are interacted with. By analyzing collected gaze data and conducting advanced semantic scanpath analysis, we find, at a high level, diverse patterns of gaze behavior: simple observation and information memorization lead to similar optical viewing strategies, while active search significantly diverges, both in regards to which areas of the visualization are focused upon and how often embellishments are interacted with. We discuss study outcomes in the context of embellishing visualizations with text for various usage scenarios.
