People with remote control?

It seems like a science fiction topic: driving people's movements by remote control. Researchers from the Prince of Wales Institute, Australia, have done so. In fact, they have guided the march of a person blindfolded through a garden through electric signals sent away. The signals reach electrodes placed behind the ears (semicircular channels) and then the order is directed to the brain. Thus, the researcher leads the volunteer as he wishes.
The system is not new, but in the experiments carried out so far the volunteers lost their balance. Now, researchers have demonstrated the importance of head position. And if the volunteers go to heaven or to the ground, they have managed to maintain the balance.
The experiment is very useful to know better one of the main characteristics of the human species, that is, to walk in two legs.
