What are you trying to achieve?: I have an existing experiment with certain routines, where I am using camera component to record participants’ activity through webcam. The goal is to use these videos later to estimate their gaze pattern, since I want high precision I can’t use WebGazer. However I need to design my own calibration tasks- I need both fixed gaze task and smooth pursuit task (screenshots of demo attached). I need to scale this according to the window size. I tried different online code repositories which didn’t work. vespr / Moving Cue · GitLab and demos / demo_eye_tracking2 · GitLab
What did you try to make it work and what went wrong?:
Attempt 1
Experiment in the first link (designed by @wakecarter), one attempt for calibration worked, I even modified the paths file to make the smooth pursuit path as I wanted. But, when I tried to make multiple copies of it, to do the same calibration multiple times, it failed and kept giving me errors like below. I changed variable names in other copies but didn’t work and in fact gave me error from the first routine from the above link.

Attempt 2
The second one, I tried but it needs scaling according to window size and also need to make another version of it where its a horizontal smooth pursuit, but since I dont have much psychopy coding experience, its not working. if there are any resources which could help me that would be great. I have questions like should I use an external coordinates/path file and then put the routine in a loop vs code everything in the routine.
