We investigate how people discover the functionality of an interactive visualization that was designed for the general public. While interactive visualizations are increasingly available for public use, we still know little about how the general public discovers what they can do with these visualizations and what interactions are available. Developing a better understanding of this discovery process can help inform the design of visualizations for the general public, which in turn can help make data more accessible. To unpack this problem, we conducted a lab study in which participants were free to use their own methods to discover the functionality of a connected set of interactive visualizations of public energy data. We collected eye movement data and interaction logs as well as video and audio recordings. By analyzing this combined data, we extract exploration strategies that the participants employed to discover the functionality in these interactive visualizations. These exploration strategies illuminate possible design directions for improving the discoverability of a visualization's functionality.
我们研究了人们如何发现为大众设计的交互式可视化的功能。虽然交互式可视化越来越多地可供公众使用，但我们仍然不太了解大众如何发现他们可以用这些可视化来做什么，以及有哪些交互可用。更好地了解这个发现过程可以帮助为大众设计可视化，这反过来又可以帮助使数据更容易访问。为了解决这个问题，我们进行了一项实验室研究，参与者可以自由使用自己的方法来发现公共能源数据的一组相互关联的交互式可视化的功能。我们收集了眼动数据和交互日志，以及视频和音频记录。通过分析这些综合数据，我们提取了参与者用来发现这些交互式可视化功能的探索策略。这些探索策略阐明了改进可视化功能可发现性的可能设计方向。
