Tobii Eyetracker Re-Calibration

Dear Inquisit Team,

I am planning to use the Tobii Plugin for my next experiment. I realized that the calibration process starts right when you start the experiment (including the Tobii Plugin), however, for my study purpose I would need the calibration process to start at a later point AND several times throughout the same experiment (i.e., re-calibrations). Is there a way to program it accordingly? Any hints are highly appreciated.


Thank you and best regards,
Jessica

The way to do this would be to split the parts into separate scripts and then execute those one after another via <batch> or a small command line script.

I have a related question. Following calibration, most eye-tracker software will provide an estimate of the calibration quality / accuracy, and offer the experimenter an opportunity to re-calibrate. That doesn't seem to happen by default with the Tobii plug-in, how can that be accomplished?

Hi Dave, sorry to nag you, but was wondering if you caught this question and were able to provide feedback.

Ah, sorry, I had missed your additional question in this thread. As far as I know, there is no way to review calibration internals and manually force re-calibration at present. The plugin handles that internally, i.e. it relies on the tracker returning "Success" as its calibration status.

Gotcha, thanks Dave. Another question: would you happen to know the criteria for successful calibration?

Not offhand, I'm afraid. I'll ask our resident eyetracking specialist for the specifics when he's back at the office and post an update here.

Hi Dave- were you able to get an update here?

Apologies -- this fell off my radar. Thank you for the reminder. I'll follow up again and should hopefully have a definitive answer for you next week.
