SMI RED Eye-Tracking System

The SMI RED Eye Tracker records eye movements at 120Hz (or 60Hz, see below).

General Setup

To test a subject

• Open iViewX on the host computer
• Open Experiment Center on the display computer (or same computer if you're using a one computer setup)
• Select your experiment in Experiment Center, make sure it's locked and connected to the host, and click record
• To stop (if stimuli duration is set to "manual"), click F12 on the display computer

Important Note: To make sure you are tracking at 120Hz and not 60Hz, in iViewX go to setup/hardware, and make sure RED 60/120 (USB) is selected as the eye tracking device. Then click on advanced and make sure that 120Hz is selected.

Troubleshooting

If the eye tracker is not working:

• make sure none of the physical connections are loose and the eye tracker (e.g., usb cables) is plugged in
• if the eye tracker doesn't kick into action when you open iViewX, then go to setup>hardware>eye tracking device, and make sure that RED 60/120 (USB) is selected from the drop-down list
