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 and arranged to form an array of multiple Braille cells, 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 passively 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 refreshable Braille display 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 and arranged to form an array of multiple Braille cells, 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 the Braille output that is displayed on the device for reading by a user via tactile interaction, each of the raised and lowered pins of the pattern held in place passively via friction between individual pins and the corresponding perforation of the body;
- and
- a text generator comprising a motorized impact driver, the text generator communicatively coupled to the controller, wherein the impact driver is configured to impact one or more of the plurality of pins of the display device to create the pattern corresponding to the Braille output.
