‘obey me ...’

Ph.d student Bernardo Dal Seno wears a skullcap mounted with electrodes and wired to a computer as he sits on a special wheel chair on March 6 at the Politecnico di Milan department in Milan. Italian researchers have developed a wheelchair that obeys mental signals sent to a computer, they said. The user is connected to a computer with electrodes on his or her scalp, and sends a signal by concentrating for a few seconds on the name of the desired destination -- kitchen, bedroom, bathroom -- displayed on a screen.
