Tag this with: “kind of cool, kind of creepy.” I had to study the diagram for a while to make sure my first impression was correct: this is simply a revision of the teleprompter allowing the interviewer to ask questions but making it possible for the person being interviewed to look directly into the camera. It used to be that directors or interviewers sat right next to the camera lens, but this still led the subjects of an interview to look slightly off camera. I guess this works on the direct eye contact level but I wonder if it doesn’t drain a bit of the human warmth out of the interview process.
That is, this may lead to better television but poorer documentation. Individual filmmakers, and audiences, will have to decide which they prefer — and the usual caveat should be added here that this has to be on a project by project basis or otherwise it becomes yet another technology in the long string of technologies that amount to “realistic” within a given era.
