Please note that this only applies to a non integrated Tobii Eye Tracker.
The Tobii Eye Tracker should always be mounted on the bottom of the screen frame. This is necessary as the eye tracker from other angles wouldn't be able to have continuous contact with your eyes and it's the assumed position by the software.
Do not mount the the eye tracker on top of the screen frame. Please also avoid tilting the eye tracker.
First attach the mounting strip for your eye tracker on the bottom of your screen frame.
Then please place your eye tracker on the mount.
