Forsyth, David Li, Sida 2016-07-07T19:57:53Z 2016-07-07T19:57:53Z 2016-04-25 2016-05 We present a novel augmented reality annotation system that can create persistent annotation in any environment. The environment is either meshed in real time or loaded from previously scanned model. The model remains invisible while providing reference to real world geometry. Annotations are persistent across multiple sessions and devices. Annotations can also be color-coded and filtered. Our interface has annotation indicators and a radar map to help users quickly locate annotations. Multiple devices can work under a synchronized network to facilitate collaborative annotation tasks. We also conducted a user study to evaluate our system. Results have shown both quantitatively and qualitatively that our system improves productivity for annotation tasks.
