Hi @f3head, thanks for your feedback, I will pass along your suggestions regarding the gaze trace circle. If your calibration has been successful then the gaze circle should follow your gaze location accurately throughout the whole screen, but your message implies that the circle remains at the top of the screen? If this is the case and the circle never follows the gaze properly but the calibration is good and other eye tracker features work, then this could indicate a potential bug in the Tobii Experience App. It may be worth trying a reinstallation of the software in case of a corrupt file during installation.
Please let us know how you get on. Best Wishes.
