插图启发的技术提供了可视化时变数据的替代方法。诸如速度线、流带、频闪轮廓和基于不透明度的技术等技术为正在可视化的当前时间步长提供了时间背景。我们通过进行用户研究来评估这些说明性技术的有效性。我们比较了受试者的能力，视觉跟踪功能使用快照，快照增强插图技术，动画，动画增强插图技术。使用用户准确性、执行任务所需的时间和用户信心作为评估技术的指标。结果表明，使用插图启发的技术提供了一个显着的提高用户的准确性和完成任务所需的时间。与增强快照相比，使用增强动画时，受试者在每个指标上的表现明显更好。
Illustration‐inspired techniques have provided alternative ways to visualize time‐varying data. Techniques such as speedlines, flow ribbons, strobe silhouettes and opacity‐based techniques provide temporal context to the current timestep being visualized. We evaluated the effectiveness of these illustrative techniques by conducting a user study. We compared the ability of subjects to visually track features using snapshots, snapshots augmented by illustration techniques, animations, and animations augmented by illustration techniques. User accuracy, time required to perform a task, and user confidence were used as measures to evaluate the techniques. The results indicate that the use of illustration‐inspired techniques provides a significant improvement in user accuracy and the time required to complete the task. Subjects performed significantly better on each metric when using augmented animations as compared to augmented snapshots.
