With Iron Man 2 only days away, at work we engineers are buzzing with our own belief-sets about the feasibility of technical aspects of the Iron Man movies. For example, most of us agree that Whiplash's ability to cut through cars with electrified whips is "impossible" whereas Iron Man's palm-mounted repulser weaponry is merely "implausible."
One topic about which we cannot build a consensus is the control mechanism by which Iron Man controls his suit. Most of us agree that it is implied in the movies that direct neural interfacing with Tony Stark's brain is the only plausible way that he is controlling the suit, as verbal commands are nearly absent, and since his hands and feet are busy fighting/flying, he must be just "thinking" commands that are somehow picked up by the suit.
Direct thought reading, through EEG or various other technologies remains technology about which I am highly dubious. I have proposed that eye-gaze tracking systems could basically control the suit, given a HUD and various pre-trained protocols.
Reading thoughts though, to me, is unlikely for the following reason: you can't accurately determine what the fish population in a pond if you simply stand at the edge of it and see what swims by.
