热图可视化是一种强大的技术，可以在显示的刺激中显示经常访问的区域。然而，通过聚合时空数据，热图失去了关于注视之间转换的信息，即扫视。相反，在注视图中，轨迹显示为过度绘制的折线，导致视觉混乱，这使得这些图表难以阅读。在本文中，我们将眼跳图作为一种结合了两种方法优点的新技术进行介绍：它将凝视频率显示为热图，并以围绕热图的彩色编码三角形矩阵的形式显示眼跳。我们通过将其应用于先前进行的眼动追踪研究的代表性示例来说明我们的技术的有用性。
Visualization by heat maps is a powerful technique for showing frequently visited areas in displayed stimuli. However, by aggregating the spatio-temporal data, heat maps lose the information about the transitions between fixations, i.e., the saccades. In gaze plots, instead, trajectories are shown as overplotted polylines, leading to much visual clutter, which makes those diagrams difficult to read. In this paper, we introduce Saccade Plots as a novel technique that combines the benefits of both approaches: it shows the gaze frequencies as a heat map and the saccades in the form of color-coded triangular matrices that surround the heat map. We illustrate the usefulness of our technique by applying it to a representative example from a previously conducted eye tracking study.
