This is a fascinating experiment — I found the technique to be super-interesting. I recommend reading the “Methods” section of the PDF: http://arxiv.org/pdf/1304.5257v1.pdf
The actual conclusions of the study are not as interesting as I expected (except perhaps some of the expert vs. novice differences), but I hope that their technique leads to more insights in the future.
