Infectious SocioPatterns visualization

wouter — Thu, 17 Feb 2011 00:24:39 +0000

In the SocioPatterns gallery we published a visualization of sixty-nine days of face-to-face contact activity among more than 30,000 persons based on data collected during the INFECTIOUS: STAY AWAY exhibition in the Science Gallery in Dublin, Ireland. Read more…

The GLEaMviz computational tool, a publicly available software to explore realistic epidemic spreading scenarios at the global scale

in: BMC Infectious Diseases

authors: Wouter Van den Broeck, Corrado Gioannini, Bruno Goncalves, Marco Quaggiotto, Vittoria Colizza, Alessandro Vespignani.

This paper discusses the objectives and functionalities offered by the GLEaMviz Simulator system, comparing these with similar publicly available software tools. A detailed description of the implementation of both the client-side and server-side components that comprise the complete system are given, and a realistic simulation example and its results are discussed.

What’s in a crowd? Analysis of face-to-face behavioral networks

in: Journal of Theoretical Biology

authors: Lorenzo Isella, Juliette Stehlé, Alain Barrat, Ciro Cattuto, Jean-François Pinton, and Wouter Van den Broeck.

This paper presents some interesting analysis of the face-to-face contact data collected with the SocioPatterns sensing platform, compare two settings with very different properties: a scientific conference and a long-running museum exhibition.

Pixelache 2011: Map me if you will

wouter — Sun, 09 Jan 2011 15:09:19 +0000

Coming March I will give a talk in the ‘Map me if you will’ seminar at the Pixelache Festival of electronic art and subcultures in Helsinki. I will also participate in the related Mapping in Progress workshop on current mapping projects such as Practice Mapping (see this blog entry). I’m really looking forward to both opportunities for auspicious interaction with the community and hope you will be there as well!

Futurisland project page

wouter — Sun, 09 Jan 2011 14:14:05 +0000

I’ve added a new project page on Futurisland, a project I worked on almost a decade ago (it’s absurd how time flies when you’re having fun). Futurisland was a web-based multi-user environment for kids developed in Flash. I had the opportunity to collaborate with some really good artists and developers for this project, the results of which I’m still proud of!

Practice Mapping project page

wouter — Sun, 19 Dec 2010 11:39:27 +0000

I just published a new project page that provides an overview of the context, objectives and results of the Practice Mapping project, which took part in the Interactivos? workshop in LABoral, Gijon, Spain, in April 2010.

Data Driven Dynamical Networks

From September 26 till October 1, we organized the Data Driven Dynamical Network workshop in Les Houches, France. We brought together a group of people from a variety of scientific backgrounds to share insights in the collection, analysis, application and visualization of data driven dynamical networks.

Connecting the Dots

On 22 October, I gave a talk about Visualizing SocioPatterns at Connecting the Dots, a Network Visualization Symposium at Harvard University, organized by Samuel Arbesman, Michael Barnett, and Jukka-Pekka Onnela from the Harvard Medical School.

GLEaMviz Simulator v2.6

We recently released a new version -v2.6- of the GLEaMviz Simulator application in which we provide an improved visualization of the epidemic spreading. The following movie provides some examples of how this new visualization shows the number of new cases at the cell-level, instead of the less precise basin-level incidence representation used in the previous versions.

The user can now also select from a number of backdrop maps onto which the visualization is projected, details of which are shown in the following figure. The left option is based on the NASA Blue Marble map, while the other two provide a more neutral base onto which the cell-level cases can be inspected with greater visual accuracy.

Samples of the three backdrop maps from which the user can choose.

Epidemic Planet

A new version of the Epidemic Planet exhibit, now with the new visualization of GLEaMviz Simulator v2.6, was shown in the Exhibition hall of the International Conference for High Performance Computing, Networking, Storage and Analysis (SC10), that was held in New Orleans, Louisiana, from November 13th to 19th. The exhibit was hosted at the booth of the Indiana University, partner of the GLEaMviz project.

The Epidemic Planet is currently also shown in CosmoCaixa Mòbil – Tecnorevolución, a traveling exhibition by the Cosmo Caixa science museum that will set up show in a number of cities in Spain.

GLEaMviz Simulator released

wouter — Tue, 03 Aug 2010 19:50:19 +0000

We recently released a publicly accessible version of the GLEaMviz Simulator. This client-server system allows its user to design, execute and visualize simulations of world-wide epidemic outbreaks. I have updated my related project page, providing a overview of this novel system’s functionality. You can, of course, also try it out yourself.

SocioPatterns papers

wouter — Fri, 16 Jul 2010 10:30:11 +0000

Our principal SocioPatterns paper has been published on PLoS ONE:

Dynamics of Person-to-Person Interactions from Distributed RFID Sensor Networks.

We also recently published two papers on the Live Social Semantics experiment in which the SocioPatterns platform was used:

Semantics, sensors, and the social web: The live social semantics experiments.

The Live Social Semantics application: a platform for integrating face-to-face presence with on-line social networking.
