This page outlines steps needed to setup eyelink for in-scanner eye tracking. Also see the SR Research participant setup video 1).

A nascent (2025-04-03) checklist document is on here

Once the camera and task PC are setup, you likely want to run SR Research EyeLink Calibration.

Other eye tracking topics include task integration, analysis, and install.

Setup Steps

  1. get keyboard and mouse
    • Prisma 1: find labeled mouse and keyboard to the left of the EPrime computer keyboard
    • Prisma 2: switch the eye tracking kvm box to 1 4)

a connected Ethernet cable can be problematical for eprime
3)
the top network port is for Avotech/Arrington
4)
may be on display #2, showing screen for Avotech/Arrington eye tracking
