Okay, so it was just remote control of a single finger, not the guy’s whole body, but I still think this experiment merits a few choice expletives, or perhaps a meme of some sort, if it proves possible to replicate.
Short version: Using noninvasive equipment (an EEG machine and a transcranial magnetic stimulation coil), a researcher in one lab imagining an action–hitting the space bar on a keyboard to fire a weapon in a game–caused the researcher on the other end to involuntarily hit the space bar on his keyboard. The guy on the receiving end likened it to a nervous tic.
Oddly, the first thing I thought of was the Heinlein story Waldo, in which the title character guides a worker wearing a suit that controls his movements through a task, conditioning him to perform the motions efficiently. I could envision recordings of an expert’s signals while performing a physical activity being used to train others, with repetition producing conditioned reflexes so that they could perform the task on their own. Or, as the researchers mention, an expert could remotely control someone on the scene of an emergency to perform a lifesaving task.
It’s a long, long way from that sort of application, even assuming (again with the caveat) that it’s legit. It’s certainly something to ponder, though.
