标题： Pupillary activity in areas of interest from visual stimuli for neonatal pain assessment

摘要： 本文将瞳孔活动指数与传统的眼动追踪指标如注视次数和持续时间进行比较，以评估新生儿疼痛。 它探讨了将瞳孔活动测量纳入以改进有助于理解认知加工和性能评估的方法的好处。 通常，使用瞳孔直径估计认知负荷涉及相对于基线的测量。 相反，我们进行了一项眼动追踪研究，使用低/高瞳孔活动指数来评估医疗专家和非专家分析带有和不带疼痛的新生儿面部图像的数据集。 这些数据是由Tobii TX300眼动追踪系统在受控光照的封闭房间中记录的。 我们的贡献是引入考虑瞳孔直径信号兴趣区域段的LHIPA计算。 结果表明，传统指标所反映的视觉注意力可能并不直接对应于两组参与者的相应认知负荷。 显示英文摘要

摘要： This paper compares the pupillary activity index to traditional eye-tracking metrics like the fixation count and duration in assessing neonatal pain. It explores the benefits of incorporating pupillary activity measures to improve methods that lead to an understanding of cognitive processing and performance evaluation. The estimation of cognitive load using pupil diameter typically involves measures relative to a baseline. Instead, we conducted an eye-tracking study using the Low/High Index of Pupillary Activity to evaluate healthcare experts and non-experts analyzing the faces with and without pain from a dataset of newborn faces. This data was recorded by the Tobii TX300 eye-tracking system in a closed room with controlled lighting. Our contribution is to introduce the LHIPA calculation considering the areas of interest segments of the pupil diameter signal. The results suggest that the visual attention reflected by the traditional metrics may not correspond directly to the respective cognitive load for both sample groups of participants.
