论文摘要
比较来自多个参与者的移动眼睛跟踪数据，而没有有关感兴趣领域的信息（AOIS），因为单个时机和坐标系统是具有挑战性的。我们提出了一种技术，即凝视螺旋，该技术根据刺激的图像内容可视化单个录音。 Slitscan可视化的螺旋布局用于创建扫描路径的紧凑表示。该可视化即使在长期跨度中也提供了多个录音的概述，并有助于识别和注释录音中的重复模式。凝视螺旋还可以用作基于既定的扫描指标的字形，可以将其投影到2D空间，以解释指标并识别相似观看行为的群体。我们介绍了基于两个自我中心数据集的示例，以证明我们在注释和比较任务中的方法的有效性。我们的示例表明，该技术有可能让用户甚至在没有手动注释的情况下比较无处不在的长期记录。
Comparing mobile eye tracking data from multiple participants without information about areas of interest (AOIs) is challenging because of individual timing and coordinate systems. We present a technique, the gaze spiral, that visualizes individual recordings based on image content of the stimulus. The spiral layout of the slitscan visualization is used to create a compact representation of scanpaths. The visualization provides an overview of multiple recordings even for long time spans and helps identify and annotate recurring patterns within recordings. The gaze spirals can also serve as glyphs that can be projected to 2D space based on established scanpath metrics in order to interpret the metrics and identify groups of similar viewing behavior. We present examples based on two egocentric datasets to demonstrate the effectiveness of our approach for annotation and comparison tasks. Our examples show that the technique has the potential to let users compare even long-term recordings of pervasive scenarios without manual annotation.
