Hands cramping up from too many video games? How about controlling games with your thoughts instead? Later this year, Emotiv Systems Inc. plans to start selling the $299 EPOC neuroheadset to let you do just that. The headset's sensors are designed to detect conscious thoughts and expressions as well as "non-conscious emotions" by reading electrical signals around the brain, says the company, which demonstrated the wireless gadget at the Game Developers Conference in San Francisco. The company, which unveiled a prototype last year, says the headset can detect emotions such as anger, excitement and tension, as well as facial expressions...

A paralysed man in the US has become the first person to benefit from a brain chip that reads his mind. Matthew Nagle, 25, was left paralysed from the neck down and confined to a wheelchair after a knife attack in 2001. The pioneering surgery at New England Sinai Hospital, Massachusetts, last summer means he can now control everyday objects by thought alone. The brain chip reads his mind and sends the thoughts to a computer to decipher. Mind over matter He can think his TV on and off, change channels and alter the volume thanks to the technology and...

BRAIN-CONTROLLED PROSTHETICS IN FUTUREFeb 12, 2005 - FreeMarketNews.comby Michael J. RossResearchers are making tremendous progress in developing artificial limbs that can be controlled by the brain activity of people wearing those limbs. These devices utilize what is known as a "brain-computer interface" (BCI), of which there are two varieties: An individual's neuronal activity measurements can be detected using "single-unit recording", in which each electrode is implanted adjacent to an individual brain cell. Alternatively, the brain activity can be measured using electroencephalography (EEG), in which electrodes are attached to the patient's scalp, to measure aggregate signals. It is expected that within...
