Animated visualization is becoming increasingly popular as a compelling way to illustrate changes in time series data. However, maintaining the viewer's focus throughout the entire animation is difficult because of its time-consuming nature. Viewers are likely to become bored and distracted during the ever-changing animated visualization. Informed by the role of foreshadowing that builds the expectation in film and literature, we introduce visual foreshadowing to improve the engagement of animated visualizations. In specific, we propose designs of visual foreshadowing that engage the audience while watching the animation. To demonstrate our approach, we built a proof-of-concept animated visualization authoring tool that incorporates visual foreshadowing techniques with various styles. Our user study indicates the effectiveness of our foreshadowing techniques on improving engagement for animated visualization.

使用视觉伏笔提高动画可视化的参与度

作为说明时间序列数据变化的一种引人注目的方式，动画可视化正变得越来越流行。然而，由于其耗时的性质，在整个动画中保持观众的注意力是困难的。在不断变化的动画可视化过程中，观众可能会感到无聊和分心。通过在电影和文学中建立期望的伏笔的作用，我们引入了视觉伏笔来提高动画可视化的参与度。具体来说，我们提出了视觉伏笔设计，在观看动画时吸引观众。为了演示我们的方法，我们构建了一个概念验证动画可视化创作工具，该工具结合了各种风格的视觉预示技术。
