Error starting ioHub server when trying to use Tobii Pro Glasses 3 with Psychopy builder eyetracking experiment

[Tanmay]

OS: Windows 11 Pro
PsychoPy version: 2024.2.5
Standard Standalone? (y/n): y
What are you trying to achieve?
I have designed a task such that i want to record eye data using Tobii Pro Glasses 3. I have included calibration, validation and the eye record routine. When i run the task, I get an error saying ioHub startup failed and the screen goes blank

What did you try to make it work?
I tried changing the experiment settings > keyboard backend to ioHub. Added the eyetracker device and model name.

What specifically went wrong when you tried that?
This is the error i am getting

Try changing the keyboard backend.

Experiment Settings In versions prior to 2025.1.0, one of the most important menu items didn’t actually appear in any of the menus. You could only access it with a mouse by clicking on the cog icon. [image] From 2025.1.0 onwards it is also accessible from the Experiment menu and via a keyboard shortcut (Ctrl-Shift-X) [image] Experiment Settings itself has seven tabs.

Hi,
Some Tobii models may require older PsychoPy versions. Try testing with an older version.
Hope this is helpful.

Iohub problem in eyetracking experiment (Tobii X3-120)

OS Win10: PsychoPy version: 2024.2.3 Standard Standalone? y What are you trying to achieve?: I try to launch a simple experiment with the eye-tracker Tobii Pro X3-120. The Tobii pro eye tracker manager v. 2.6.1 is installed and working (the calibration works). The Tobii eye tracker support is installed in the builder… But the experiment does not launch and I can’t figure out why. Does someone have a clue? Or is it still necessary to use the 2022.2.5version? Regards, Damien What did you…

I tried installing an older version and running it, the problem is persistent.

Hi, I am planning to do the same procedure as yours. Have you solved this problem or have you changed your method to meet your requirement? It seems that psychopy is not compatible for wearable eye-tracker, such as Tobii Pro Glasses2/3. I am thinking about change other means to integrate stimuli with gaze point. I really expect your reply if you have any ideas about this! Wish you good luck!
