Hey, I'm currently working on some new pieces for a future exposition.

What I need is to create a Max patch that will be wired to surveillance cameras, the cameras will determine the exact position of the spectator in the room, and depending on that position, it will determine a certain FM band. Basically when the spectator move, it change the FM band, by moving in the room, he can catch different radios or white noise. I have absolutely no idea where to start, that's why I need your help, would I need an arduino or anything like that?
