How can I tell if my eye tracker is working properly?

Does my eye tracker work fine?

If your screen based eye tracker shows up in the Eye Tracker Browser and doesn't display any error message, it is likely to be properly connected and functional.

If you want to check its performance, proceed to the eye tracker configuration, perform a participant calibration and "check calibration".
