Influence of Presentation Mode on User's Mental Map in Temporal Sequence Data Visualization
Wenlu Wang, Ningyue Peng, Haiyan Wang, Chengqi Xue · 2020
Spatial aggregation and small multiples are two mainstream visualization presentation methods for temporal sequence data. This study compares the effect of spatial aggregated and small multiples in mental map construction with three task genres: peak value identification (Task 1), variation tracking (Task 2), and trend comparison (Task 3). Spatially aggregated timestamps get transited through animations. Task completion time favors small multiples in Task 1, but spatial aggregation with animated transition is more favorable in Task 2 and Task 3 in terms of completion time and error rate. Subjective rating results are aligned with behavioral performance measures. This research can guide future temporal sequence data visualization design.
