                <p>At the heart of WebGazer.js are the tracker and regression modules. The tracker module controls how eyes are detected and the regression module determines how the regression model is learned and how predictions are made based on the eye patches extracted from the tracker module. These modules can be swapped in and out at any time. We hope that this will make it easy to extend and adapt WebGazer.js and welcome any developers that want to contribute.</p>
