我们根据经验评估人们感知二维路径上编码的非恒定时间和速度的程度。在我们的图形感知研究中,我们评估了文献中关于直线和曲线路径的九种编码。当x轴和y轴已经编码了其他数据维度时,例如在地图上绘制行程时,可视化时间和速度信息是一个挑战。在时间地理和运动分析等学科中尤其如此,这些学科通常需要可视化时空轨迹。一种常见的方法是使用2D+时间轨迹,这是2D路径,其中时间是一个额外的维度。然而,目前还没有关于如何在这些路径上表示时间和速度的指导方针。我们的研究结果为InfoVis设计人员提供了关于使用和避免使用哪些编码的明确指导;特别是,我们建议尽可能使用颜色值来表示编码速度,使用分段长度来表示编码时间。
We empirically evaluate the extent to which people perceive non-constant time and speed encoded on 2D paths. In our graphical perception study, we evaluate nine encodings from the literature for both straight and curved paths. Visualizing time and speed information is a challenge when the x and y axes already encode other data dimensions, for example when plotting a trip on a map. This is particularly true in disciplines such as time-geography and movement analytics that often require visualizing spatio-temporal trajectories. A common approach is to use 2D+time trajectories, which are 2D paths for which time is an additional dimension. However, there are currently no guidelines regarding how to represent time and speed on such paths. Our study results provide InfoVis designers with clear guidance regarding which encodings to use and which ones to avoid; in particular, we suggest using color value to encode speed and segment length to encode time whenever possible.
