                    <p>It may be necessary to pause the data collection and predictions of WebGazer.js for performance reasons.</p>
                    <pre><code class="javascript hljs">
webgazer.pause(); //WebGazer.js is now paused, no data will be collected and the gaze callback will not be executed
webgazer.resume(); //data collection resumes, gaze callback will be called again
