Researchers have come a step closer to developing a device that will enable people to write and manipulate objects by reading their mind.
Signals from the brain are measured by 128 electrodes affixed to the subject's scalp, similar to an electroencephalogram (EEG). With the help of a software programme, specific signals are picked out among the nebulous mass of information.
The device could provide a way for paralysed patients to operate computers, or for amputees to operate electronically controlled artificial limbs. But it also has non-medical applications, such as in the computer games and entertainment industries.
The German researchers hope to develop a commercial version of the device as an aid for paralysed patients and amputees.
The brain-computer interfaces could have a range of uses beyond the medical. "Signals from the brain give you a fraction of a second advantage," NewScientists quoted John Chapin, an expert as saying.
The device could make a novel game controller and be used in other ways. The researchers have even begun testing the machine as a driving aid, as it can sense a sudden reaction and control a vehicle's brakes before even the driver can.
Scientists are now developing a cap that won't have to be attached directly to the scalp making it easier to use and cause less skin irritation for the wearer.
