多视图可视化对于在复杂的数据集中发现模式非常有用，但是关于如何使用它们的研究很少。我们进行了一个控制实验，研究的认知策略和上下文切换使用的可视化和不同的任务类型的组合作为自变量，并收集定性和定量的数据。为了收集数据，使用了基于纸张的测试，记录参与者的互动，眼动追踪，大声思考技术和视频记录。与文献中的建议不同，我们的研究结果表明，当考虑双视图可视化时，上下文切换的时间成本可能并不显著，并且类似的可视化实际上可能会引起更多的干扰。此外，正交组合似乎可以帮助用户识别模式。对空间关系的集中注意力和类比推理也是重要的认知能力。
Multiple-view visualizations are useful for finding patterns in complex data sets, but little research has been done on how they are used. We performed a controlled experiment to study cognitive strategies and context switching by using a combination of visualizations and different task types as independent variables, and collecting qualitative and quantitative data. To collect the data, paper-based tests, logging of participants' interactions, eye-tracking, think-aloud techniques, and video recordings were used. Unlike suggestions in the literature, our results show that when considering dual-view visualizations, the time cost for context switching may not be significant, and similar visualizations may actually cause more interference. Furthermore, orthogonal combinations appear to aid users in recognizing patterns. Focusing attention and analogical reasoning on spatial relationships are important cognitive abilities as well.
