The present invention is a visual prosthesis which restores partial vision to patients blinded by outer retinal degeneration. While visual prosthesis users have achieved remarkable visual improvement to the point of reading letters and short sentences, the reading process is still fairly cumbersome. In the present invention the visual prosthesis is adapted to stimulate visual braille as a sensory substitution for reading written letters and words. The visual prosthesis system, used in the present invention, includes a 10&#xd7;6 electrode array implanted epiretinally, a tiny video camera mounted on a pair of glasses, and a wearable computer that processes the video and determines the stimulation current of each electrode in real time.

Text reading and translation in a visual prosthesis

The present invention is a visual prosthesis adapted for implantation in the brain, and more particularly with an electrode array adapted for implantation in the Calcarine Sulcus of the visual cortex. The electrode array of the invention has electrodes on each side and spaced appropriately for the Calcarine Sulcus and driven by an electronic circuit within a hermetic package small enough to be implanted with a skull.
