I'm curious if anyone ever seen or heard of someone hacking camcorder face motion tracking. Surely everyone seen those green squares that keep focus on the the subject's face. I was wondering if there's a mad scientist working in the field of video image processing who was able to tap into the face motion tracking to output it to a automated robotic drive/head on which a given camcorder is attached to. This way the camera can be set to keep the face in the shot autonomously while on a curved slider for multi-cam interview shooting.
Any comments are really appreciated.
If this doesn't exist, it surely would enrich production value to small two-men multi-cam shoots.

Any thoughts?
