This is like the "interrotron" see link, but simpler - a camera that has two lenses that point opposite ways and a little up so that an interviewer can hold the cam in the same place that they usually hold the mike like when sports casters interview sports players, right between the two, you know like the mike goes back and forth, well this cam would pick up the emotions and the interplay of facial ticks and communications between the two talkers, the interviewer and the interviewee.
