Tobii Eyetracker Plugin

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Win10
PsychoPy version (e.g. 2024.2.4 Py 3.8): 2025.1.1 Py10
Standard Standalone Installation? (y/n) Y
Do you want it to also run online? (y/n) N
What are you trying to achieve?:
Properly integrate Tobii Fusion
What did you try to make it work?:
Installed PsychoPy, installed Tobii Plugin, then testing.
What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.

Calibration works perfectly. But when Start recording, below error seems happen every frame.

“C:\Users\User\AppData\Roaming\psychopy3\packages\Python310\site-packages\psychopy_eyetracker_tobii\tobii\eyetracker.py”, line 458, in _getIOHubEventObject
right_gx, right_gy, right_gz = eye_data_event[‘right_gaze_origin_in_trackbox_coordinate_system’]
KeyError: ‘right_gaze_origin_in_trackbox_coordinate_system’
Traceback (most recent call last):

So above error message continously fill the log window, and nothing related to gaze info saves.

Try installing the newest version and you should not encounter that error anymore.

I Installed using the latest github version yesterday. Was it recently changed? Especially Plugin?

Hello,

Can you please share if you have Tobii eye tracker working with PsychoPy? I am using Tobii Pro Nano (60Hz). Calibration works well, validation doesn’t. Eye tracker record component doesn’t trigger the eye tracker. I am using PsychoPy 2025.1.1

Please help.

Hello,

Can you kindly share if you got the eye tracking working with the latest PsychoPy version?

Best wishes

Hello, sorry for late reply. Yes, I am using Pro Fusion with latest version, but not using plugin, but directly communicate using tobii SDK library implemented in PsychoPy.

Are you using mac or windows? I will check if I can help.

@Becca is there anything ET users can do to help test the tracker components before roll-out? It seems that with every new release the ET components break. I just upgraded to 2025.1.1 and I am encountering some issues when calibrating/validating.

Hi Jason,

Absolutely - we actually have an alpha tester group for keen users who want to bug test - I shall drop you an email to get you added to the group!

I verified ET works with Titta on 2025.1.1 so it is something with iohub.
