second screen to monitor real time gaze position

GEYUQING

Hey guys,

I'm working on initiating a second psychopy window on another monitor to show participants' real time gaze position. the second window needs to show the exact same stimulus the participant is watching plus overlaid real time gaze position. From what I understand in previous discussions i need to modify the source code in openexp/_canvas/psycho.py and initiate another window with 'screen' set to 1. And in every draw function i need to draw the stimuli on the second window as well.

I need to see the real time gaze position through the entire experiment so I guess it can't be done with python inline script. But im not sure how to draw a gaze indicator every frame in the source code.

Also I would like to know if there is a easier way to copy the canvas of experiment.window to the second window.

Hi,

Sorry to give you such a vague advice, but if I remember correctly a colleague of mine has implemented something like that. His code is on github, but without much explanation. Maybe you can email him and ask for advice?
