In my current eye tracking set up, I am using the EyeX in front of a TV (which is connected as an external display to the computer running windows).
When i try calibrating the user, after the process , it says
“Detection failed” .
In the log file (present in C://Program Data/Tobii), for the calibration failure, it says:

Some Firmware error. I have checked that all the softwares and firmwares are up to date from the EyeX engine. I have checked with multiple EyeX trackers and both gives the same error. Any idea whats going wrong?16/09/2014 at 15:32 #1657Konstantin [Tobii]Keymaster
what EyeX version have you used?
We did just recently release the latest version 0.10.xxx you can get it through auto-update or download it here: http://developer.tobii.com/eyex-setup/
Included is actually also a new firmware, please try that and let me know if it makes any difference.

with a stack trace like that it sure is a scary error message! But the reason for the “operation failed” could be as simple as that the tracker cannot detect your eyes. Have you checked out the eye tracker mounting guidelines?
A related cause could be that the display area isn’t set up correctly, because that can lead to inferior tracking.03/11/2014 at 21:13 #1956SybrenParticipant
Sorry for the x-referencing on the forum: http://developer.tobii.com/community/forums/topic/eyex-engine-calibration-fails/#post-1955
May be related, I get the same error message. Although my colleague was able to calibrate successfully several times.
