      abstract = {<p>Many eye-tracking data analyses rely on the  Area-of-Interest (AOI) methodology, which utilizes AOIs to  analyze metrics such as fixations. However, AOI-based  methods have some inherent limitations including  variability and subjectivity in shape, size, and location  of AOIs. In this article, we propose an alternative  approach to the traditional AOI dwell time analysis:  Weighted Sum Durations (WSD). This approach decreases the  subjectivity of AOI definitions by using Points-of-Interest  (POI) while maintaining interpretability. In WSD, the  durations of fixations toward each POI is weighted by the  distance from the POI and summed together to generate a  metric comparable to AOI dwell time. To validate WSD, we  reanalyzed data from a previously published eye-tracking  study (n = 90). The re-analysis replicated the original  findings that people gaze less towards faces and more  toward points of contact when viewing violent social  interactions.</p>},
