This wooden matrix is a large-scale replica of Jacques Bertin's reorderable physical matrices. It shows a subset of the World Value Survey, a series of questionnaires that assess people's moral values across countries and years. This physical visualization is interactive as row and columns can be manipulated, promoting engagement and collaboration.
This 18x20 matrix was built by Mathieu Le Goc in the Fablab Digscope with Charles Perin and Romain Di Vozzo, on the occasion of the 25th birthday of the IEEE VIS conference in Paris, France. Follow the link below for more details on the matrix, including photos and videos.
