可变字体技术的出现——排版参数如粗细、x高和斜度可以很容易地在一个范围内调整——使得将顺序、间隔或比例数据编码成仍然可读的文本成为可能。这对于在可视化的文本标签中表示附加信息（例如，字体粗细可以在地理可视化中表示城市大小）或文本本身（例如，句子的预期阅读速度可以用字体宽度编码）具有潜在的价值。然而，我们不知道不同的参数，这些形状的复杂变化，是如何被人类视觉系统感知的。如果没有这些信息，就很难选择适当的参数和映射函数来最大限度地感知参数范围内的差异。我们从绝对感知和可注意差异（JNDs）的角度对拉丁字体的七种排版参数进行了经验特征描述，以帮助可视化设计师为包含文本的可视化选择排版参数，并支持排版师和字体设计师选择这些参数的哪个级别来实现正常文本，强调文本和不同标题之间的区别。
The advent of variable font technologies---where typographic parameters such as weight, x-height and slant are easily adjusted across a range---enables encoding ordinal, interval or ratio data into text that is still readable. This is potentially valuable to represent additional information in text labels in visualizations (e.g., font weight can indicate city size in a geographical visualization) or in text itself (e.g., the intended reading speed of a sentence can be encoded with the font width). However, we do not know how different parameters, which are complex variations of shape, are perceived by the human visual system. Without this information it is difficult to select appropriate parameters and mapping functions that maximize perception of differences within the parameter range. We provide an empirical characterization of seven typographical parameters of Latin fonts in terms of absolute perception and just noticeable differences (JNDs) to help visualization designers to choose typographic parameters for visualizations that contain text, as well as support typographers and type designers when selecting which levels of these parameters to implement to achieve differentiability between normal text, emphasized text and different headings.
