1. A method of processing written words in a visual prosthesis comprising: providing a visual prosthesis including a camera, video processor, and implantable stimulation system configured to stimulate visual neurons; recording a visual scene with the camera and transferring data representing the visual scene to the video processor; converting the data to visual stimulation patterns; presenting the visual stimulation patterns including the visual scene to a user through the implantable stimulation system; scanning the data for patterns representing written characters; switching to a reading mode upon recognition by the video processer of patterns representing written characters, wherein said reading mode includes: converting the written characters to Braille characters; encoding the Braille characters into the visual stimulation patterns, creating altered stimulation patterns; and presenting the altered visual stimulation patterns including the Braille characters to a user through the implantable stimulation system; switching back to presenting the visual stimulation patterns including the visual scene through the implantable stimulation system, after presenting the altered visual stimulation patterns including the Braille characters.
