Hi,
Just to update:
I have made a very preliminary version of a Processing library that you can download here: http://jorgecardoso.eu/processing/EyeTribeProcessing/
It provides gaze and eye position, and calibration within Processing.
I hope to be able to polish it a bit and add more examples in the next months. (Development is a bit slow because I don't have constant access to a computer that supports USB 3.)
Any feedback will be welcomed!
Cheers,
jorge
