Problem with Setting up Tobii Eye Tracker in OpenSesame

Hello everyone,

I hope you're all doing well. I'm currently facing an issue while trying to set up my Tobii Pro Spectrum eye tracker to work with OpenSesame, and I could use some guidance.

I followed the installation instructions provided on the OpenSesame documentation for Tobii eye trackers:

1. Tobii Guide
2. Anaconda Download

I'm running Windows 10 and using Anaconda for managing my Python environment. After successfully setting everything up, I attempted to run an eye-tracking experiment using the Eye-tracking template with Tobii as the tracker type. However, I encountered the following error:

Traceback (most recent call last):

    self.canvas.set_bgcolor(colour)
AttributeError: 'Psycho' object has no attribute 'set_bgcolor'

I'm using a Tobii Pro Spectrum eye tracker, and it appears that there's an issue with the background color setting in the PyGaze library. I've looked through the options in OpenSesame, but I can't find anything related to 'set_bgcolor'.

Has anyone encountered a similar problem, or does anyone have any suggestions on how to resolve this issue? Any help or advice would be greatly appreciated.

Thank you in advance!
