在本文中，我们使用瞳孔直径作为衡量六个不同的任务在常见的网络地图认知负荷的指标。针对不同的基图收集了两组眼动追踪数据集（共37名参与者和1328项试验）。我们发现不同任务的平均瞳孔直径存在显著差异，表明自由探索的认知负荷低，搜索、多边形比较、直线跟随的认知负荷中等，路线规划和集中搜索的认知负荷高。在试验中，瞳孔直径也随着时间的推移而变化，这可以解释为搜索和集中搜索的认知负荷增加，而直线跟随的认知负荷减少。这些结果可用于根据用户的认知负荷调整地图和地理可视化。
In this paper we use pupil diameter as an indicator for measuring cognitive load for six different tasks on common web maps. Two eye tracking data sets were collected for different basemaps (37 participants and 1,328 trials in total). We found significant differences in mean pupil diameter between tasks, indicating low cognitive load forfree exploration, medium cognitive load forsearch,polygon comparison,line following, and high cognitive load forroute planningandfocused search. Pupil diameter also changed over time within trials which can be interpreted as an increase in cognitive load forsearchandfocused search, and a decrease forline following. Such results can be used for the adaptation of maps and geovisualizations based on their users’ cognitive load.
