I am implementing an eye tracker using emgucv (openCV C# wrapper), So far i was able to detect iris center and eye corner accurately.

As the next step i want to get the screen coordinate where user is focusing (also known as gaze point),As a beginner to image processing , i am completely unaware of gaze mapping and gaze estimation.

I would be thankful , if you provide any code snippets or algoritms to perform gaze mapping to retrieve gaze coordinate on screen .

Thanks in advance

If you want to research the field in more depth, there's this interesting piece of research called "EyeTab: Model-based gaze estimation on unmodified tablet computers". It might have some of the information you want, or at least help you understand the field more.
