Oh no, absolutely no way this can be used for evil.
From the article:
PossessedHand, being developed jointly by the University of Tokyo, Japan, and Sony Computer Science Laboratories, also in Tokyo, electrically stimulates the muscles in the forearm that move your fingers. A belt worn around that part of the subject’s arm contains 28 electrode pads, which flex the joints between the three bones of each finger and the two bones of the thumb, and provide two wrist movements.
They call it “POSSESSED HAND”! I think I saw a movie about that once that didn’t end well. I figure it’s only a matter of time until they hijack your body and make you pull the trigger of a gun, the pin from a grenade, or detonator on a bomb. Maybe you get nabbed coming out of the mall, they hook up these machines to you, and send you on your way to do the controller’s bidding. Strap-on assassins. Tell me that doesn’t scare you.
Other than the very obvious doom this will bring, it’s pretty neat.
