news from Jun 2008 ... data viz VI - presentation

I attended the 6th 'Data Viz' meeting in June at Jacobs University Bremen.

The meeting followed on from successful workshops in Germany and New Jersey where work and progress in statistical graphics was discussed. This meeting focussed on "Information Visualization in Today's Multimedia Society" and included interesting and innovative presentations from some of the world'd best known researchers in Information Visualization and Statistical Graphics.

I changed my title to "is a treemap more than just a tree?" following heated discussion about this particular form of layout. Can a 2D layout of a tree be justified? I argued that it can if we use the two dimensions to represent two dimensional orderings, and that our spatial squarified layout algorithm achieves this - allowing us to see geography and hierarchy concurrently in large data sets. To an extent, the clue is in the name ... 'treemap' - but the map needs to be effective.

There was a real focus on 'R' at the meeting and some interesting work using techniques that are familiar to cartographers and geographers involving animation of spatio-temporal data and an R implementation of proximity brushing.

news from May 2008 ... cartographic journal paper

Susanne Bleisch, Stefan Nebiker and I have had a paper accepted for publication in The Cartographic Journal.

The paper 'Evaluating the effectiveness of representing numeric information through abstract graphics in 3D desktop virtual environments' compares use of 2D and 3D graphics for basic estimation and comparison tasks and presents evidence that such tasks are no less effectively performed in our 3D environment than is the case in 2D. However, tasks take longer in 3D environments than when performed in 2D. Susanne's ongoing PhD work is evaluating whether these efficiency losses are offset by gains not measured in our tests. The work was originally presented at the August 2007 ICA Commission on Visualization and Virtual Environments meeting in Helsinki :

news from May 2006 ... three months already

Emma and I became parents for the first time in March with the arrival of Fred and Isaac.

We've had a few hiccups, and learned quite a lot (!) but we're all doing fine three months on and ... and are almost sleeping through the night!

The guys are now at the stage where their random arm wavings might almost be attempts to grab things (!)

Some early photos are available for those who are interested.

news from March 2006 ... presentations at gisruk 2006

David Lloyd and Susanne Bleisch presented their research at the 14th national GIS research conference in Nottingham.

Susanne presented the results of her user tests with the GeoNOVA software - 'Planning Hikes Virtually How Useful are Web-based 3D Visualizations?' - showing that some users feel confident in using 3d maps for hike planning despite misinterpreting some aspects of the representation.

David's paper - 'Investigating catchment area anomalies for a north England store' - presented statistical and visual analysis of spending patterns and related data to hypothesize about causes of anomalies identified by a major retailer.

news from March 2006 ... new arrivals

I recently became a father for the first time ... and second time.

Isaac and Fred are fine and Emma is recovering well. I have taken some paternity leave and vacation to help us all adjust to life at home.

I have put some pictures and more details online for those who are interested.
