Run the application created with Portalgraph and open the settings menu (usually by pressing F12). Check the option for "Tracker App Auto Start," then select Camera from the dropdown menu below. This setting will automatically start the camera tracking software the next time the application is launched.
Select EyeCenter as the tracker position, then click Apply. If the eye coordinates and eye rotation values are all set to zero, no further configuration is needed.
Click Next to proceed to the calibration screen, then click Camera.
If you are using a built-in webcam positioned just above a standard 16:9 monitor, enter the screen size in the camera tracking settings screen and click OK.
If this is not the case, check Advanced Mode, then manually enter the screen size and specify the camera’s coordinates and angles. For the XYZ axes, positive directions are upward, to the right, and foward, respectively, relative to the screen.
The camera tracking app is pre-configured for a standard built-in PC webcam, so if you are using an internal camera, simply select the camera and click Apply to complete the setup.
If you are using a specialized camera, click Calibration to start a countdown. During this countdown, use a measuring tool to position your face so that your eyes are exactly 50 cm in front of the camera. Once the countdown finishes, the camera’s field of view and focal length will be adjusted accordingly.
Here are some tips to enhance your experience:
Lower Camera Resolution: Set the camera resolution lower to reduce CPU load (640×360 is sufficient).
High-FPS Camera: A high-FPS camera improves responsiveness.
Wide-Angle Camera: A wide-angle camera allows for more movement within the frame but may introduce distortion towards the edges of the field of view.
Recommended Camera: The developer uses a camera with a 120-degree field of view and 60fps.
Check Camera Specs: You can verify the camera’s supported resolution and FPS in the Windows Camera app under "Video Settings."
