Set SCREENDIST: distance between screen and participant's eyes
I used the PyGaze plugin in OpenSesame to connect with Tobii X60.
Because the distance between the screen and the participant is about 90 cm in the experiment, I was concerned that the inappropriate value of SCREENDIST will influence the output of eye position.
I tried to put an
inline before and after the
pygaze_init to define it, but it did not work.
As a result, I revised the value of SCREENDIST in \OpenSesame\Lib\site-packages\pygaze\defaults.py. The experiment runs without any problems and the calibration report shows the exact value I set.
I want to know whether the outcome will be more precise due to the change? Or will it be messed up...
