我们展示了一项眼动追踪研究的结果,该研究比较了长、密集、复杂和分段线性空间轨迹的不同可视化方法。此类数据的典型来源是运动物体位置的时间离散测量,例如运动生态学中记录的动物 GPS 轨迹。在受试者内重复测量用户研究中,比较了节点链接可视化技术的四种变体,以及以下定向链接表示:标准箭头、锥形、等距箭头和等距彗星。此外,我们还研究了渲染顺序对这些链接的光环可视化的影响以及节点泼溅的有用性。链接可视化技术的所有组合都针对不同的轨迹密度级别进行了测试。我们使用了三种类型的任务:路径追踪、最长链接识别以及轨迹簇密度估计。结果以任务完成时间、任务解决准确性和两个眼动追踪指标的统计评估的形式呈现。这些客观结果得到了参与者主观反馈的总结。我们研究的主要结果是锥形链节的性能非常好。然而,我们讨论等距彗星和等距箭头是感知方向信息的一个很好的选择,与显示器的缩放级别无关。
We present the results of an eye tracking study that compares different visualization methods for long, dense, complex, and piecewise linear spatial trajectories. Typical sources of such data are from temporally discrete measurements of the positions of moving objects, for example, recorded GPS tracks of animals in movement ecology. In the repeated-measures within-subjects user study, four variants of node-link visualization techniques are compared, with the following representations of directed links: standard arrow, tapered, equidistant arrows, and equidistant comets. In addition, we investigate the effect of rendering order for the halo visualization of those links as well as the usefulness of node splatting. All combinations of link visualization techniques are tested for different trajectory density levels. We used three types of tasks: tracing of paths, identification of longest links, and estimation of the density of trajectory clusters. Results are presented in the form of the statistical evaluation of task completion time, task solution accuracy, and two eye tracking metrics. These objective results are complemented by a summary of subjective feedback from the participants. The main result of our study is that tapered links perform very well. However, we discuss that equidistant comets and equidistant arrows are a good option to perceive direction information independent of zoom-level of the display.
