Make sure that the eye trackers are correctly and stably attached to the monitor
Avoid direct sunlight on the eye trackers or other strong light sources
Keep your eye trackers clean
Sitting position
Make sure that you are sitting/standing as usual and that you are centered in front of the eye tracker (the distance for a proper recognition is 45 to 100 cm)
Your eye trackers should always be facing you so that they can see your eyes well
USB slot
The eye trackers need a stable power supply. It is best to plug your eye trackers directly into a PC, docking station or USB hub with power supply.
We do not recommend connecting the eye trackers to a USB hub with multiple other input devices (such as a mouse or keyboard), as there may be problems between the different input devices.
