Integrating PsychoPy eye tracking with a cheap webcam on a desktop computer?

[BrianOdegaard]

Hi everyone -

Has anyone had luck with implementing eye tracking in PsychoPy using a cheap webcam, or some other inexpensive option?

I have some projects in my lab that use PsychoPy and our expensive EyeLink eye tracker. The setup works great, but it’s in use 40 hrs/wk running participants in various projects, and I have a need to get another cheap eye tracking setup running in another experiment room in my lab. Any quick/dirty/cheap solutions that you all have working, that could recommend?

Thx!

You could try to tie into the https://webgazer.cs.brown.edu framework. Looks like there have been a few posts about it in PsychoPy with JS/Pavlovia.

It took me about two hours to get a shabby prototype working. It will easily take me a day or more to have something nice. On the upside, I like to document things carefully, so once I got something, it could be a lot easier to for you to adopt. Don’t wait for it though, since the moment I need to …

Hi JJ, Yes I would say if you could download this one demos / demo_eye_tracking2 · GitLab it will stay maintained by the team (it’s the version that we now use in workshops!) Hope this helps, Becca

Hi everyone! If you’re interested in trying out the demo_eye_tracking framework, I’ve built a short study based on it.
It runs directly in your browser and uses webcam-based eye tracking.
It only takes about 3–6 minutes: https://run.pavlovia.org/yangxiy/demo_eye_tracking2
