FAQ: What is the ideal configuration EyeLink 1000 / EyeLink 1000 Plus Desktop mount?

[Sam]

Proper placement of the EyeLink system is very important for data quality and ease of use. Please make sure your setup conforms to the recommendations below.

• Screen Distance and Placement
  • Eye-to-Screen: The distance from the participant to the monitor should be at least 1.75 times the monitor's width.
    For example, with a 50 cm wide monitor the participant should be at least 90 cm away and the camera would be placed ~35cm in front of the screen.
    
  • Screen Height: The participant's eye level should be aligned with the top 25% of the screen.
    
• Camera Distance and Placement
  • Camera-to-Eye Distance: The Desktop mount should be placed 50-70 cm from the participant's eyes.
    
  • Centering: The camera should be centered with the display monitor.
    
  • Vertical Placement: The camera and illuminator should be positioned as high as possible without obstructing any part of the display from the participant's point of view.
    If you can see a gap between the bottom of the monitor and the top of the camera from the participant's perspective, the camera is too low and needs to be raised.
