General advice for post-processing ET data
At the risk of perhaps going slightly off topic for this forum, I was wondering what people’s strategies were for post-processing data from eye tracking studies using pygaze / opensesame?
I am sure Edwin’s pygaze analyser is as awesome as pygaze itself, but from my brief look, this appears to focus on producing visual outputs – heatmaps / scanpaths etc. (please do correct me if I am wrong!). I will be looking to determine other common metrics, (time to first fixation, total dwell time etc.) relating to particular, arbitrary areas of interest, and was just wondering what other people’s approaches were.
I’m quite confident I could write a script or program to crudely achieve this by parsing/processing the pygaze log file, but I don’t want to ‘re-invent the wheel’ (or more specifically invent a not-that-great wheel that takes me ages).
Using pygaze/opensesame for gaze-contingent stuff seems great, and pygaze analyser looks fantastic for heatmaps and other visualisations…But, I’m going to be looking for the metrics outlined above for arbitrary areas of interest.
As usual, any advice most gratefully received – even if it is “no choice but to create a script yourself!”
