* **FOV, Focal Length**: Enter the camera's field of view (FOV) and focal length. These values are set automatically during calibration.
* **Calibration**: Click to start calibration. Position yourself so that the center of each eye is directly in front of the camera at a distance of 50 cm, and wait for the countdown. The FOV and focal length will be automatically configured.
