Are your eyes not getting detected?

If the eye tracker can't detect your eyes or you can't calibrate properly, please check all of the things below.

• Make sure you have mounted the eye tracker correctly. Check the mounting guide for instructions.
  This only applies to non-integrated eye trackers.
  
  
• Re-do the display setup in case the placement of the eye tracker was incorrectly aligned. Check out our display setup guides below. This only applies to non-integrated eye trackers. 
  
  Display setup - Tobii Core software
  Display setup - Tobii Experience application
  
  
• Make sure that you are positioned correctly in front of the eye tracker. Check out our position guide for visual references.
  
  

✅ If all of the above checks out, please make sure of the following:

• Don't sit in direct sunlight as that will interfere with the eye tracker since it uses near-infrared light. Also, make sure there are not any other sources of infrared closeby to the tracker. 
  
  
• Make sure that you don't have any type of glass that blocks out near-infrared light or is bifocal. If you've had Lasik surgery, that could also be a cause. Please check out our article about glasses, lenses and eye surgery.
