Is anybody planning to include a free-marker tracking method like the EHCI?
The RANSAC method to track the head position it seems quite good.
Have a look at here:

I suggest also to read the wiki discussion, there are still some issues like:
- if one moves his head out of the camera's view, basically the face
detection is gone forever. even if one moves back his head, the reference
points are gone
