Design guidelines for augmenting short-form videos using animated data visualizations

摘要

Short-form videos are an increasingly prevalent medium for storytelling in journalism and marketing, of which information can be greatly enhanced by animated data visualizations. However, there is no prior research that systematically investigates how to augment such short videos with data visualizations in an effective way. We conducted a design workshop with experienced video, animation designers and visualization experts to discuss principles and practices for augmenting short-form videos with data visualizations. After the workshop, we summarized the participants' design considerations and proposed 20 design guidelines. We further collected design purposes of the participants and associated these purposes with the guidelines. Finally, we conducted a crowd-sourcing study and a task-based evaluation to validate the effectiveness and usability of the guidelines. Results indicate that our guidelines can significantly improve the videos accompanied with data visualizations and help novices easily obtain desired knowledge when augmenting videos.
