WonderFlow：以旁白为中心的动画数据视频设计
WonderFlow: Narration-Centric Design of Animated Data Videos
AI总结：
WonderFlow是一个以旁白为中心的交互式数据视频创作工具，通过语义链接、自动语音合成和结构感知动画库，简化了旁白与动画同步的数据视频制作流程。
摘要：
创建带有音频旁白的动画数据视频需要大量时间和精力，并且需要专业知识。用户不仅需要设计复杂的动画，还需要将书面文本脚本转换为音频旁白，并使视觉变化与旁白同步。本文介绍了WonderFlow，一种交互式创作工具，它促进了以旁白为中心的动画数据视频设计。WonderFlow允许作者轻松指定文本与相应图表元素之间的语义链接。然后，它利用文本转语音技术自动生成音频旁白，并将旁白与动画对齐。WonderFlow提供了一个可视化结构感知的动画库，旨在简化图表动画创建，使作者能够将预先设计的动画效果应用于常见的可视化组件。它还允许作者在一个统一的系统中预览和迭代完善他们的数据视频，而无需在不同的创作工具之间切换。为了评估WonderFlow的有效性和可用性，我们创建了一个示例画廊，并进行了用户研究和专家访谈。结果表明，WonderFlow易于使用，并简化了具有旁白-动画交互的数据视频的创建。
英文摘要：
Creating an animated data video enriched with audio narration takes a significant amount of time and effort and requires expertise. Users not only need to design complex animations, but also turn written text scripts into audio narrations and synchronize visual changes with the narrations. This paper presents WonderFlow, an interactive authoring tool, that facilitates narration-centric design of animated data videos. WonderFlow allows authors to easily specify a semantic link between text and the corresponding chart elements. Then it automatically generates audio narration by leveraging text-to-speech techniques and aligns the narration with an animation. WonderFlow provides a visualization structure-aware animation library designed to ease chart animation creation, enabling authors to apply pre-designed animation effects to common visualization components. It also allows authors to preview and iteratively refine their data videos in a unified system, without having to switch between different creation tools. To evaluate WonderFlow's effectiveness and usability, we created an example gallery and conducted a user study and expert interviews. The results demonstrated that WonderFlow is easy to use and simplifies the creation of data videos with narration-animation interplay.
