Tobii Eye Tracker: Infant Calibration

eyetracking

#1

Hi all,

I have a Tobii X3-120 eye tracker and will be conducting an experiment with 2-year-olds.

One feature of Tobii Studio that I really enjoy is the “infant calibration” mode – animated gifs/short vidoes are played instead of fixation points, greatly enhancing the attention of infants.

I see that in the ioHub documentation, only “circle_targets” are currently supported for calibration from psychopy when using a tobii. I’m wondering if anyone has found a workaround or other methods for displaying alternative fixation points for calibration.

Thanks so much for your help, community!

Best,
Phil

Hi Phil,
I just noticed this post recently, in case you still need a solution:
I programmed a package to integrate PsychoPy and Tobii eye tracker (T60) for developmental research, psychopy_tobii_infant.

I used images of animals which would resize itself continuously to attract the child (10 to 12-month-olds).
It was effective in my case, but I’m not sure how 2-year-olds will react. Maybe you would need to modify the code for your experiment :slight_smile:

Hope that helps!

Hi Phil,

Thank you for the reply.
I’m currently rewrite the package for improvement, so there must be some bugs that I need to fix.
If you want a more stable Tobii controller, psychopy_tobii_controller is useful. My scripts are based on it.

I plan to finish the project in this weekend or next week. If you use it and encounter problems, please let me know. Comments/suggestions are much appreciated!

Good luck!
Yuhan
