Adding screen distance to raw data log
Hi developers of PyGaze,
Thank you for the great work!
I am using a Tobii Spectrum 600 Hz with Tobii PRO SDK (TobiiPro.SDK.Python.Windows_18.104.22.168) to collect task-contingent eyetracking data through PyGaze implementation in Open Sesame software. In my raw data log, data is lacking about the distance between the eyes and the screen (screen distance), while I need this information to analyse oculomotor behavior (e.g. with GazePath).
How can I change the libtobii.py file in PyGaze in order to add the screen distance for both eye seperately to the raw data output? Or would it be better to calculate distance post-hoc after data collection?
Also see the attached script that I am using.
Thanks again and kind regards,
