The computer my wife uses for net meetings and patient e-visits has a camera with a field of view limited to her head and shoulders, and a simple curtain behind.
I wonder how many user cameras have a wide enough field to show arm movements, or (horrors!) the keyboard and mouse themselves? Do keyboard clicks show up in the audio, and can those be timed to estimate which keys are pressed? 340 m/s divided by 44 kHz is 8 millimeters; fingers and hands move much more slowly than sound. I don't know, but this could be a security hole worth investigating. Perhaps fat consulting gigs for those who develop marketable expertise.
