pred_struct_final.psyexp (127.0 KB)
Hi there,
I hope somebody with experience of using iohub to link up Psychopy with a Tobii eye-tracker can help with the following. I have attached my experiment. The experiment runs fine (on a Windows 7 Dell laptop) but we have been experiencing intermittent connectivity issues with the eye-tracker.
Essentially, the eye-tracker disconnects unexpectedly duuring the experiment, so no samples are collected. We perform several rounds of calibration (using tobii infant controller), and we often realise the eye-tracker has stopped sending any data (no eye image) when we get to the calibration routine, but when looking at the hdf5 outputs it is clear no samples were collected for several trials prior to us identifying the problem. Now, these issues may be entirely due to the eye-tracker (it’s fairly old), but I was hoping psychopy may throw some useful errors to help troubleshoot.
In the last run, I got the following error, which to me does suggest there may indeed be a connectivity issue (but I don’t know much about iohub).
Can somebody with more expertise confirm whether this is indeed the case? Or could something else have caused this error? Bizzarely, as far as I can tell from the hdf5 output, the eye-tracker did not actually disconnect during this run (samples were collected for the entire duration of the experiment). But could it be that there was an intermettent connectivity issue - so the eyetracker disconnected only for a short time? This would be very worrying indeed…
I hope the above makes sense, but let me know if you need more info.
Any thoughts would be greatly appreciated, this has been giving us lots of headaches and the RA’s are getting a bit frustrated with all the issues.
Thanks,
Chiara
