= !WebGazer.js - Eye-tracking library for common webcams =

''Description''

  !WebGazer.js an online eye tracker that uses common webcams already present in laptops and mobile devices to infer the eye-gaze locations of web visitors on a page in real time. With this it e a natural experience to
everyday users that is not restricted to laboratories and highly controlled user studies. !WebGazer.js has two key components: a pupil detector that can be combined with any eye detection library, and a gaze estimator using regression analysis informed by user interactions. 

   Advantages of !WebGazer.js:
 
  - Real time gaze prediction on most major browsers
  
  - Self-calibration from clicks and cursor movements

  - Easy to integrate with a few lines of JavaScript

  - Swappable components for eye detection

  - Multiple gaze prediction models
