I can already think of a few enhancements that could be done. Make the lens swivel so that it can track someone with a smaller field of view so that accuracy increases. Add a zoom able lens so that the camera can track you and zoom in on you if necessary for whatever reason. And possible zoom in on a specific body part, such as the hands. Of course, motors make things more likely to break, but I think the pay off might be worth it.
