This paper presents PapARVis Designer, an authoring tool that allows users to augment static visualizations with augmented reality. The tool integrates static and virtual visualization design in one environment. It provides previews of augmented reality visualizations on desktop to avoid switching devices. It also automatically validates designs to ensure consistency. A user study found that with the preview and validation features, non-experts could more quickly create valid augmented static visualizations compared to a baseline tool lacking these features. The paper discusses design opportunities and limitations around authoring 3D and dynamic augmented visualizations as well as multiple augmentations for collaboration.
