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.
Claims20
A refreshable Braille displaying device, comprising:
- a body having a front surface and a rear surface, and a plurality of perforations that run through the body between the front and rear surface;
- and
- a plurality of Braille pins individually accommodated within the plurality of perforations of the body, each of the plurality of pins configured to be impacted between a first position extending through the body and protruding out of the front surface, and a second position extending through the body and protruding out of the rear surface, wherein one or more of the plurality of pins are configured to be impacted to create a pattern of raised and lowered pins, the pattern corresponding to a Braille text that is displayed on the device for reading by a user via tactile interaction, the raised and lowered pins of the pattern held in place via friction between the pins and the body.
A refreshable Braille display system, comprising:
- a controller with computer-readable instructions for receiving a non-Braille input and converting the non-Braille input into a Braille output;
- a mechanical display device comprising a perforated body, and a plurality of Braille pins individually accommodated within a plurality of perforations of the perforated body, the pins held in place via friction between each individual pin and a corresponding perforation, wherein one or more of the plurality of pins are configured to be impacted to display a pattern of raised and lowered pins corresponding to the Braille output, the displayed pattern corresponding to the Braille output configured to be read by a user via tactile interaction;
- and
- a text-generator device comprising an impact driver, a motor for actuating the impact driver, a surface for receiving the display device thereon, a printhead configured to position the impact driver relative to a Braille pin of the received display device, and a microprocessor.
A method, comprising:
- receiving a non-Braille text;
- translating the non-Braille text into a Braille text characterized by a pattern of dots;
- and
- displaying the Braille text by adjusting a position of one or more Braille pins of a display device to create a series of raised and lowered pins corresponding to the pattern of dots, wherein following the adjusting, the raised and lowered Braille pins are held in place in the display device only via friction.
