Maybe they should E.M.P. the contestants as they come into the tournament.
I would agree with all you say, I think the touch screen operated shoe theory is ridiculous. Far more likely as you say to have some device that emits some signal, morse code vibrations for example, to indicate the move. That just leaves how he inputs the moves, which I think is either done by him somehow, perhaps in morse code, by tapping on some input device on his body, or otherwise having an accomplice that inputs the moves/ communicates the engine moves to the player.
One things is clear to me, that with all the attention on this guy, he would be a fool not to be constantly refining/ changing the way he cheats. Whatever means he is using, I do not imagine is groundbreaking, so if I was FIDE, I would get in a consultant or two from the casino security industry, and sort this out once and for all.
All the above predicates that this guy is cheating. Given the nature of this guys performances and improvement, as well as the fact I don't see any grandmasters queueing up to declare this guy the new coming of chess, that he is cheating is a foregone conclusion to me. That this nonsense has not been sorted out by FIDE makes chess look a joke, imo.
