I am looking for suitable toolbox/package to analyze the eye-tracking data, using R, Matlab or Python. We have a Tobii T60 system and eye tracking data is simultaneously recorded with EEG data. We are using an E-prime extension, so the data is in an Excel (CSV) format. The presented stimuli are videos with fixed AOIs. First we want to do some simple analysis, such as overall looking time and fixations (to compare AOIs). The second step will be to determine the onset of saccade from one AOI to another AOI. Finally I want to visualize the results in heatmaps and scanpaths. Can anyone recommend a toolbox/package that is compatible with our data format and research questions? Thank you in advance!
You would need to detect eye regions first, so you can use a landmark detector such as DLIB (or deep learning based such as FPN)
there are other toolboxes out there for eye tracking, but you will need to check if they suit your needs though, I believe this may serve your needs (can handle e-prime csvs i believe)

For Python, there is Pygaze

Haven't used it myself, but seems quite extensive...
Kim Astor do you know if this would work with ouputs from tobii eye-trackers that included videos instead of pictures?
Kim Astor thanks for the response. That sounds very interesting! I just got some raw data with tobiitx300, so my output has no AOIs defined in it. If timestudio allows you to do that, I will give it shot. Would you happen to have your workflow uploaded to their database?
Best wishes,
Helio
Kim Astor Does timesutdioproject read hdf5 file format ? Or would it read .mat file extracted from the hdf5 file?
I want to define aoi/roi defined by heatmaps, and run other metrics such as time to first fixation, dwell time and number of fixations in aoi. I have 40 static images, viewed over 15 s by 32 participants presented in different/random order.
Kim Astor Thanks for your response. Do you know if I can read .mat files into timestudio or is there a particular order of data that must appear in the files?
Best,
Ayesha
