Quickstart Guide

---

Start by connecting a webcam to your PC and placing it at the top of the screen in the middle. Make sure that the lens is pointing forward and positioned parallel to the screen.

For laptops with built-in webcams, nothing needs to be done.

Launch the HoloGold Eyetracker Server application. Then, press START to run the server. For most webcams, this will make the indicator light start flashing.

In most cases, increasing the Resolution beyond 1080p will not be necessary.

Smoothing will stabilize tracking but may impact responsiveness.

Launch the HoloGold application.

Configure the Display Profile (monitor size and aspect ratio).

To save the setting as default, access Configuration:Display

from the top menu bar.

Check if the installed webcam appears in the list below:

• Logitech MX BRIO
• Logitech C920
• MacBook Air 15inch M2 2023 built-in webcam
• NexiGo N980P (*Recommended)
• Spedal 920

If the webcam is not listed, simply proceed to the next step (STEP6-A).

If the webcam is listed, access Configuration:Webcam from the top menu bar and load the provided webcam configuration file. Then, proceed to the next step (STEP6-A).

Correctly setting the Webcam Position before running webcam calibration should improve the resulting eyetracking accuracy.

Use a tape measure or a ruler to measure the distance between the top center of the screen and the center of the webcam lens, and specify the offset values.

For example, if the webcam camera lens is located 3 cm above the top-center pixel of the screen, the Y-offset should be set to "3 cm".

The three-step webcam calibration - tilt, depth and offset - should be completed in the given order.

If the webcam model was selected from STEP5, the depth and offset calibration can be skipped. Otherwise, the entire calibration procedure must be performed.

Ensure that Display Profile and Webcam Position are both configured properly before proceeding.

Depth calibration requires a tape measure, and having access to a small box-shaped object with a flat top at hand will help achieve a more accurate tilt/offset calibration.

To save the setting as default, access Configuration:Webcam from the top menu bar.
