Japanese researchers have created systems which allow control of characters in online games through the mind alone. But it's in a good cause:
A paralysed man using only his brain waves has been able to manipulate a virtual Internet character, Japanese researchers said on Monday, calling it a world first.
The 41-year-old patient used his imagination to make his character take a walk and chat to another virtual person on the popular Second Life website.
The patient, who has suffered paralysis for more than 30 years, can barely bend his fingers due to a progressive muscle disease so cannot use a mouse or keyboard in the traditional way.
In the experiment, he wore headgear with three electrodes monitoring brain waves related to his hands and legs. Even though he cannot move his legs, he imagined that his character was walking.
Some World of Warcraft players actually want to live this way.
