      <ul>
        <li>Ensure proper lighting to avoid glare and shadows on the face.</li>
        <li>Position your face such that it is fully visible to the camera.</li>
        <li>For glasses-wearing users, clean the lenses to minimize reflections.</li>
        <li>Hold each gaze direction (Center, Left, Right) steadily for 3-5 seconds.</li>
        <li>Ensure the entire eye region is visible during gaze capture.</li>
        <li>For "Blink" data, blink naturally and avoid rapid eye movements.</li>
        <li>Repeat the data collection process for multiple sessions to ensure diversity in data.</li>
