Abstract
A refreshable braille display device is provided comprising a plurality of Braille pins running through a perforated body of the reader, the pins arranged in the spacing and order of Braille dots of standard Braille cells. The Braille reader may be coupled to a device for Braille text generation via selective hammering or impacting of Braille pins. From a default position where all pins of the reader are raised relative to a first, front surface of the reader, one or more pins are selectively impacted in a sequence to create a Braille pattern of raised and lowered pins based on a desired text conversion.
