论文摘要
动画过渡可帮助观众遵循相关可视化之间的变化。指定有效的动画需要重大努力：作者必须选择动画，提供过渡参数并协调阶段的时间安排的元素和属性。为了促进这一过程，我们提出了Gemini，这是一种声明性的语法和推荐系统，用于单视统计图形之间的动画过渡。双子座的规格根据高级视觉组件（标记，轴，传说）和组成规则来定义过渡“步骤”，以同步和串联步骤。有了这种语法，双子座可以推荐动画设计来增强和加速设计师的作品。 Gemini列举了给定的起始和最终状态的上演动画设计，并使用先前的知觉研究为这些设计进行了对这些设计的排名。为了评估双子座，我们既进行了关于机械Turk的形成性研究，以评估和调整我们的排名功能，又进行了一项总结性研究，其中8位经验丰富的可视化开发人员在D3中实施了动画，然后我们将其与Gemini的建议进行比较。我们发现，大多数设计（9/11）在双子座中都是可复制的，许多（8/11）可以通过对建议进行编辑（8/11），并且双子座的建议避免了多个参与者错误。
Animated transitions help viewers follow changes between related visualizations. Specifying effective animations demands significant effort: authors must select the elements and properties to animate, provide transition parameters, and coordinate the timing of stages. To facilitate this process, we present Gemini, a declarative grammar and recommendation system for animated transitions between single-view statistical graphics. Gemini specifications define transition "steps" in terms of high-level visual components (marks, axes, legends) and composition rules to synchronize and concatenate steps. With this grammar, Gemini can recommend animation designs to augment and accelerate designers' work. Gemini enumerates staged animation designs for given start and end states, and ranks those designs using a cost function informed by prior perceptual studies. To evaluate Gemini, we conduct both a formative study on Mechanical Turk to assess and tune our ranking function, and a summative study in which 8 experienced visualization developers implement animations in D3 that we then compare to Gemini's suggestions. We find that most designs (9/11) are exactly replicable in Gemini, with many (8/11) achievable via edits to suggestions, and that Gemini suggestions avoid multiple participant errors.
