设计在复杂可视化的可解释性中起着关键作用。许多应用领域利用大量数据进行预测，从显示传染病传播的地图到显示全球气温变化的折线图。这些可视化利用了视觉系统从一组相似对象中提取信息的能力，这一过程被称为集合处理，以及认知系统将颜色等视觉特征与疾病或温度等有意义的概念联系起来的能力。可视化必须同时考虑感知能力和认知能力。目前还不清楚哪一种最能提高理解能力：是利用集合过程设计的可视化，还是使用与底层数据一致的语义共鸣颜色。为了解决这个问题，向参与者展示了为整体过程而设计的可视化，因为他们使用的是仅具有单一色调的颜色编码，或者是为语义过程而设计的，因为他们根据数据的意义优先考虑颜色对齐。参与者观看了使用这些颜色的条形图，并判断图表中描绘的温度是上升还是下降。如使用信号检测测量d‘进行量化，参与者使用单色调调色板比使用语义更具表现力的多色调调色板对趋势信息的敏感度更高。我们的结果表明，可视化可能通过选择利用集成过程的颜色而不是选择语义兼容的颜色来更有效地传达趋势信息。此外，我们的结果表明，语义兼容性对趋势方向的敏感度没有影响。
Design plays a key role in the interpretability of complex visualizations. Many applied domains utilize large quantities of data to make predictions, ranging from maps showing the spread of infectious disease to line graphs displaying global temperature changes. These visualizations tap into the visual system’s ability to extract information from groups of similar objects, a process known as ensemble processing, and the cognitive system’s ability to relate visual features such as color to meaningful concepts such as disease or temperature. Visualizations must consider both perceptual and cognitive abilities. It remains unclear which best improves comprehension: visualizations designed to exploit ensemble processes or that use semantically resonant colors that align with the underlying data. To address this question, participants were shown visualizations designed for ensemble processes in that they used color encodings with only a single hue or designed for semantic processes in that they prioritized color alignment with the meaning of the data. Participants viewed stripplots using these colors and judged whether the temperature depicted in the graphs was increasing or decreasing. As quantified using the signal detection measure d’, participants’ sensitivity to trend information was higher with the single-hue palettes than with more semantically expressive multihue palettes. Our results suggest that visualizations may convey trend information more effectively by selecting colors that exploit ensemble processes rather than selecting semantically compatible colors. Moreover, our results showed semantic compatibility had no effect on sensitivity to trend direction.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
