Partial edge drawings (PED) of graphs avoid edge crossings by subdividing each edge into three parts and representing only its stubs, i.e., the parts incident to the end-nodes. The morphing edge drawing model (MED) extends the PED drawing style by animations that smoothly morph each edge between its representation as stubs and the one as a fully drawn segment while avoiding new crossings. Participants of a previous study on MED (Misue and Akasaka, GD19) reported eye straining caused by the animation. We conducted a user study to evaluate how this effect is influenced by varying animation speed and animation dynamic by considering an easing technique that is commonly used in web design. Our results provide indications that the easing technique may help users in executing topology-based tasks accurately. The participants also expressed appreciation for the easing and a preference for a slow animation speed.

翻译：图的局部边绘制（PED）通过将每条边细分为三段，仅呈现其端节点邻接的存根部分，从而避免边交叉。形变边绘制模型（MED）通过动画扩展了PED的绘制风格：在避免新增交叉的前提下，动画使每条边在其存根表示与完整线段表示之间平滑形变。先前关于MED的一项研究（Misue and Akasaka, GD19）的参与者报告称动画导致视觉疲劳。我们开展了一项用户研究，通过考虑网页设计中常用的缓动技术，评估不同动画速度与动画动态对该效应的影响。结果表明，缓动技术可能有助于用户准确执行基于拓扑的任务。参与者对缓动技术表达赞赏，并偏好较慢的动画速度。
