Cambiera: Visual Analytics on the Surface

Researchers

Summary

Group information sharing typically occurs in phases in which individuals drop in and out of phases of joint and parallel work. In collaborative visual analytics, for example, group members need to be able to work on their own sub-projects, in which tentative hypotheses can be created, followed, and rejected. The analystsí desire for private work is in tension with their desire to capitalize on the groupís shared effort. The group may produce pieces of information that could be useful to the analyst; but the analyst, immersed in his or her work, may not want to be distracted.

In this project, we explored the idea of trading off individual and group work in a context of collaborative visual analytics. We introduced the concept of collaborative brushing and linking as the basis of an implicit visual awareness tool across multiple users.

Cambiera is a system for information foraging activities on a multi-touch tabletop display. Group members can individually search for documents, browse through search results, and read documents. Cambiera includes a number of (collaborative brushing and linking) features that highlight where collaborators have found or read similar documents. The video below shows most of these features and further information can be found in the EuroVis publication.

Evaluation

We also conducted an evaluation on Cambiera. We gave 12 pairs the 2006 VAST contest dataset to work with and explored how they used Cambiera during an analysis session. As a result we describe novel findings in regards to analysis behavior and how it affected which information each individual analyst was considering in regards to the other person. We also describe some measures of success. Our VAST paper and Chapter 7 of my PhD thesis contain more information on the study.

Prizes

  • The system design won the (3rd) best paper award at EuroVis 2009.
  • The evaluation paper won a best paper honorable mention at VAST 2010.

Examples


Each person has their own keyboard on the screen and can start searching for relevant terms in a document collection.

There are a lot of features in the system to help show the group what each person has looked at and found. Watch the video below to see a number of additional ones and read the paper for a complete description.
