CSI Miami has to be the worst offender for ridiculous levels of tech.
Yeah, in the show its probably all green-screen or hidden projectors. Stuff like that just doesn't exist in reality, or it is a very expensive custom job only possible if your name is Samsung or LG.
Interacting with a computer via non-physical means, its possible now, but entirely at a research/development level. Nowhere near mass consumer level. Also nowhere near interaction with the subconscious either.
