According to a recent article by physorg.com, scientists have actually invented a computer that can read brain waves! The “brain computer interface (BCI)” was recently demonstrated at a four-day European Research and Innovation Exhibition in Paris and works by reading a signal in the mind when focusing on a certain letter. This technology could allow people with various dissabilities a way to write and communicate. It is anticipated that there will be nearly 100 million potential users of BCI technology worldwide, including 16 million sufferers of cerebral palsy, a degenerative brain disease, and at least five million victims of spinal cord injury.
