SenseMap: Supporting Browser-based Online Sensemaking through Analytic Provenance (VAST 2016)

The paper is accepted by the VAST 2016 conference!

The paper introduced a new tool called SenseMap that help users with online sensemaking for daily tasks such as find a camera, book a holiday, etc.

The tool is available as a Chrome plugin (very early stage = lots of bugs 🙂 and there is more information here: sensemap.io. Any comment/feedback is welcome!

Provenance for Sensemaking Workshop at IEEE VIS 2014 (Paris, France)

I am co-chairing a workshop on Provenance and Sensemaking at the IEEE VIS conference week in Paris. The submission deadline has now passed, but you can still join the discussions at the workshop during the conference. Hope to see you there!

VAST Visual Analytics Challenge 2014 – Honorable Mention

This year, the Visual Analytics challenge organised by the IEEE VAST (Visual Analytics Science & Technology) conference again had a mini-challenge on Twitter data, and it is (near) real-time this time. The task is to monitor the Twitter feed and provide (near) real-time updates on important events that are happening and find information related to a suspected kidnapping.

Our entry won a ‘Honorable Mention for Effective Support for Analytic Sensemaking’, a step away from getting an award. You can see the system working in the demo video below (best in full screen with sound on).

A User Study on Curved Edges in Graph Visualisation

Recently there has been increasing research interest in visualizing graphs with curved edges to produce more readable visualizations. While there are many automatic techniques, little has been done to evaluate them empirically. In this paper we present our study on the impact of edge curvature on graph readability by comparing the path finding performance on graph visualizations with varied curvature levels. We also asked the participants to provide subject ratings of the effectiveness and aesthetics of different types of curved edge.
