In that scenario, yes. I just think that scenario is highly hypothetical.
But maybe that's just because I don't see any reason for something like Natal to be used to control generic devices like a TV. Yeah you could control a TV using some ridiculous gestures, but a remote control is simple, effective and fool-proof (no changing channels due to making the wrong gesture).
