Dr. Rosen and I are investigating how people annotate different common chart types when they want to communicate information using them. As part of this project, we ran a study to understand how visualization students annotate group bar charts when asked to answer high-level questions by performing low-level analytical tasks. We found interesting usage patterns of annotations. More details can be found in our viscomm paper.
We along with our collaborators at the University of South Florida are working on building a peer review dashboard where we want to apply the nudge theory to improve the quality of peer reviews. The main idea is to use behavioral nudges in a way so that students spend more time doing peer reviews and generate good quality peer reviews that are useful for their peers.
