Hi @truccker, thanks for your query. Blinking recovery should indeed be within a few milliseconds. Have you tried selecting the option to ‘improve calibration’ as found within the Tobii System Tray Icon under user settings? This may help deal with any possibly issue of trackability.
Please also ensure there are no strong sources of IR light nearby the eye tracker including an open window facing the screen (if possible).
May also be worth checking if the issue persists in another room or environment to eliminate the role of local conditions. Thanks for the your patience whilst we try to resolve this issue for you.
