Exploring data using visualization systems has been shown to be an extremely powerful technique. However, one of the challenges with such systems is an inability to completely support the knowledge discovery process. More than simply looking at data, users will make a semipermanent record of their visualizations by printing out a hard copy. Subsequently, users will mark and annotate these static representations, either for dissemination purposes or to augment their personal memory of what was witnessed. In this paper, we present a model for recording the history of user explorations in visualization environments, augmented with the capability for users to annotate their explorations. A prototype system is used to demonstrate how this provenance information can be recalled and shared. The prototype system generates interactive visualizations of the provenance data using a spatio-temporal technique. Beyond the technical details of our model and prototype, results from a controlled experiment that explores how different history mechanisms impact problem solving in visualization environments are presented.
使用可视化系统探索数据已被证明是一种极其强大的技术。然而，此类系统面临的挑战之一是无法完全支持知识发现过程。用户不仅仅是查看数据，还会通过打印硬拷贝来制作可视化的半永久性记录。随后，用户会对这些静态表示进行标记和注释，要么用于传播，要么用于增强他们对所观察内容的个人记忆。在本文中，我们提出了一个用于记录可视化环境中用户探索历史的模型，并增强了用户注释其探索的能力。一个原型系统用于演示如何召回和共享这种溯源信息。该原型系统使用时空技术生成溯源数据的交互式可视化。除了我们的模型和原型的技术细节之外，还展示了一项对照实验的结果，该实验探索了不同的历史机制如何影响可视化环境中的问题解决。
