Setting up eye tracking

Return to Summary
Connecting Equipment in the MRI Control Room:

Silver Box for Eye Tracking
The silver box for eye tracking is located in a cardboard box beneath the stimulus presentation PC in the MRI control room.
 

Cable Connections
Connect the gray cable to the PC (USB) port.
Connect the black cable to the gray BNC cable located beneath the desk.

Connecting to the BNC Cable:

Ensure the BNC cable is securely connected to both the equipment and the designated port on the desk.

Launching Eye Tracking Systems:

Software Setup:
The ViewPoint software is installed on the lab PC labeled “SCOPE I-1”.
While ViewPoint can be installed on other PCs, newer versions may cause compatibility issues, preventing the software from working correctly.

Opening ViewPoint:
On the desktop, open the “ViewPoint” folder.

Launch “ViewPoint-USB-60x3_64.exe” to start the software.

ViewPoint Setup:

This PC will be used to launch and record with ViewPoint.

The PC should be connected to the MRI room display via HDMI to show the ViewPoint interface for calibration purposes.

Stimulus Presentation (Optional Synchronization):

If synchronization is required, prepare a second PC to control stimulus presentation.
The ViewPoint command PC setup is pending further instructions (Coming Soon).
Synchronization is not needed if not specified.

Camera Setup in the MRI Room:

Preparing the Camera:
Remove the camera cover.

Rotate the black knob to securely attach the camera to the mirror.

Adjusting the Camera Position:
The orange base should initially align with the left eye, but it can be adjusted for the right eye or front-facing view with the use of a small screwdriver.
 

Mounting the Mirror:
Attach the mirror to the head coil.

Continue with “Calibration and Recording.”
