EyeLink Settings

Screen Dimensions:

  • Width: 830mm - Width of the viewable portion of the projected Stim PC monitor image.
  • Height: 470mm - Height of the viewable portion of the projected Stim PC monitor image.

NOTE: These values may change, depending on the position of the projector screen relative to the projector mirror.
Stimulus paradigm will also determine the screen position - use tape on the MSR floor to help with projector screen placement.

Display Resolution of Stim PC monitor:

  • Width: 1920 pixels
  • Height: 1080 pixels

This setting only needs to be changed, in FINAL.INI, if a different display resolution is used to the one above.

Eye-to-Screen Distance:

  • 1000mm - Distance from the eye to the top of the viewable portion of the projected Stim PC monitor image.
  • 1050mm - Distance from the eye to the bottom of the viewable portion of the projected Stim PC monitor image).

NOTE: These values may change, depending on the position of the projector screen relative to the gantry chair/participant. e.g. 1500mm.
Some Operators also measure Distance from the eye to the center of the viewable portion of the projected Stim PC monitor image.

EyeLink lens defualt setup:

  • 35mmm - Used by most Operators. 50mm lens is available on the MSR shelving if required.
    • Swap back to 35mm after use.
  • "I put the eye tracker very close to the participant, so smaller lens will give me a wider angle to cover the whole visual fields" Yali Pan.

Camera-to-Screen Distance:

  • 150mm - Only applicable in "Remote" mode (which is not used), so can safely be ignored.
