We have developed an open-source eye-tracking library Confero. Now it’s time to finish the ConferoAnalytics.

R or Python? Well, we are constrainted by the fact that Confero saves data in HDF5 files. The only R library I can find on CRAN is H5, which does not compile on my mac, whereas I know Python/Pandas supports HDF5. So that’s that, at least for now.

Next up, what visualization framework to use? Florian and I have developed some R functions that work well … well enough fro publications, but not interactive. It’s also a hack to get ggplot to work with background images, etc.

I have been moving toward plot.ly since a few months ago when it became open-source. According to this blog post you can do overlays, but it is not supported as a native feature and it takes a lot of tweaking to get the iframe alight right … come on, Plot.ly.
