Tobii eyetracker experiment GET_DEV_INTERFACE_ERROR error message

Builder

Hello,

OS: Win10
PsychoPy version: 2023.2.3
Standard Standalone? y
Eyetracking device; Tobii X3-120
What are you trying to achieve?:

I am trying to build an experiment in the PsychoPy Builder with the Tobii X3-120 eyetracker.
I am just at the very beginning and I have just put a calibration routine and an trial with an etRecord component.

What did you try to make it work?:

I don’t really know where to begin…

What specifically went wrong when you tried that?:

When I run the experiment, I get an error message (only when one of the eyetracking element is active).

I think I understand there is a problem with iohub… But I don’t know what the problem is and how to address it. Could someone give me a clue?

Best regards,
Damien

If you look through the forum and github issues you’ll see this has been an issue with the shift in how plugin handles. For now, version 2022.2.5 is recommended for eye tracking. You can’t simply just change the run version because there are missing folders and python library compatibility issues, so you should downgrade your psychopy version.

Just be aware that with all the changes from 2022.2.x to 2023.x, I’d recommend recreating your script in v. 2022, otherwise you’ll probably get many errors and warning message. We had success with just copying the routines from the 2023.x script to a new one opened with v. 2022.2.5
