GP3HD eye tracker - how to call functions

Hi,

I got a GP3HD recently and I am trying to check how it works with PsychoPy. Out of the box it gives me Looks in ROIs but I want a bit more info. I came across the API for this tracker but I am not sure how to call these classes/functions.

For instance for the extract below how do I get the left_gaze_x? Also, (probably long shot) is it possible to import these data to GP3’s software analysis to get scanpaths e.t.c.?

I attach a minimal exp which I use to test eye tracker and psychopy
myproject.psyexp (15.5 KB)

Many thanks in advance for any advie/tips/support.
