Facial recognition goes beyond face tracking, by running an algorithm that identifies an individual by their facial features. It can use face tracking as one of its base technologies, yes, but not with the same goal and it generally needs different and more detailed data points than the simple face tracking you'd use for an AR feature like this one.

I'm sorry, but I'm really not sure what you're trying to say with Andross, nor have you explained the connection to the Virtual Boy. Are you trying to spin some great conspiracy where Nintendo is monitoring us via facial recognition and has somehow been doing that since the 90s?
