Amazing news
Shawn Kelly, a senior systems scientist at
Carnegie Mellon University, has developed a computer chip that
translates camera images into electrical pulses that the nerves inside
the brain can understand. The result is vision.
The cameras are
incredibly small and mounted to a pair of glasses. The digital
information picked up from the camera is sent along a wire to a thin
film surgically implanted in the back of the patient's eye, between the
sclera and the retina. The electrical signals stimulate the nerves in
the retina, and that allows the patient to see. The system is powered
via induction -- not much current is necessary since the electric field
doesn't have to penetrate far into the head.
