Tobii Calibration

Hello,

I'm working on an eye-tracking study with infants and would like to tweak the tobii eye-tracking calibration protocol.

1) If possible, I would like to change the target dots to some kind of animated graphic with sound to attract attention
2) I would like the option to re-do calibration if it fails. As it currently stands, when calibration fails, it starts the experiment right away without collecting any eye-tracking data.

If anyone has any ideas for either of these questions, I would appreciate it!

Thanks!
Annie

    Check out this discussion. The first part should get you started with your childfriendly calibration targets.

    I never worked with Tobii, but I am surprised that there is no menu or something similar that you enter after calibration. As a workaround, you could put the calibration in a loop-sequence structure, together with a response item, and repeat the loop until a certain key was pressed. So, set the repeat value of that loop to a super high value (>1000), and add to the break_if field, something like [response] == 'c', if c was the key to continue.

    Does that help?
