Refreshable Braille Displays and Braille Notetakers are portable devices for reading and writing in braille.
Braille is a reading method for persons who are blind. Braille consists of a combination of raised dots that represent a single letter or a shorthand of common letter combinations. Electronic Braille is read through a refreshable Braille display using raised rounded pins.
Portable Braille devices can create and read notes, email, and browse the Internet among other useful tasks. Some prefer to use their Braille display alongside other technology such as a computer or mobile device. Many refreshable Braille displays and note takers can be connected to these devices either wirelessly or through a USB.
What kinds of electronic braille displays are there?
Typical Braille displays are a single line of Braille cells, and a person reading can move the line of Braille displayed by use of cursor keys. Braille entries are made with a keyboard that consists of six keys representing a position in the Braille cell and a space bar to separate letters/combination of letters.
Some braille displays and notetakers offer traditional typing keyboards for inputting text. Examples include the Mantis from Humanware or the BrailleSense from HIMS.
