Video Turing tests and face recognition

This post starts off topic, but does get back on topic in the end. Please bear with me.

I assume the readers of this blog know what the classic Turing test [Wikipedia] is. To pass the Turing test a machine must be able to impersonate human responses to such a degree that a human can't distinguish between the machine and a human based on their responses.

The original Turing test is meant to test artificial intelligence. Similar tests could be used to test other artificial entities - such as video.

A Video Turing test (TM) could be defined as follows. Set up a wall with a window and with a video monitor that displays a stream captured by a camera on the other side of the wall.To pass the Video Turing test (VTT), it needs to be impossible for a human to distinguish the window from the monitor.

There are various levels of VTTs. A 2D VTT assumes a static one-eyed viewer. A 3D VTT would also work with a two-eyed viewer, but still static. A virtual reality VTT would also work with a moving viewer.
