Eye-tracking based on a webcam is, from my experience, terrible.

No software that I've found, that required only a standard webcam, has worked better than a simple "move mouse slowly downward when I'm looking down". This is simply because there's not enough data to interpret into angles precise enough to calculate a screen position.

That said, Pygaze is free and open source and can work with webcams, and python can be interfaced with unity. There are some tools out there, but you might end up just working with sockets between the two.

If you accept the use of hardware, I know tobii provides a unity sdk. There are also cheaper alternatives, that work with pygaze.
