How to analyze where a person is looking?

Question

Software and Internet Services

It is necessary to analyze where a person is looking on the monitor screen, perhaps more than once. This technology is used in the development of games and 1s. I would like to know how it is possible to organize what software to use, what hardware.

Answer 1

Now neural networks are in vogue. You can prepare a "training base" from photos indicating the direction and try to train it to determine the direction. If it works in optical text recognition, in principle, it should also work here.

Answer 2

Something similar was done on the basis of Microsoft's Kinect - a window in the form of an LCD monitor that changes the image depending on the movement of the observer. A complete illusion is created that the window is real.
You have a similar task, to intercept a person’s gaze, only process it differently.
Perhaps even a slight change in the position of the head is enough for you - and Kinect catches this.
Here I have a large monitor - I definitely turn my head =) More

window (home window) and windows (microsoft OS) from the point of view of the search engine are the same.
But there should be more information on the Internet, I remember that I once studied this topic, I wanted to do this myself.
