Hi guys,
after


after coming across a 2004 installation by Carsten Nicolai titled "anti" where he used a theremin as an element for presence sensing, I was wondering if this principle could be extended to greater distances.

Let me better explain: would it be possible to use the principle of the theremin antenna for sensing the presence of people inside a room (not simply hands on short distance)?

I imagine an application in interactive multimedia context on which I would be very interested to learn more.

Any suggestion, link, idea is greatly appreciated
