A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use ...
It has either a braille keyboard or a Qwerty Keyboard, a speech synthesizer, and a 32-[2] or 18-column refreshable Braille display, depending on model. The "VoiceNote" is the same device without a braille display. The BrailleNote GPS is an 18 or 32 cell BrailleNote with an External GPS module, BrailleNote GPS.
The concept design of a braille e-book by Yanko Design. A braille e-book is a refreshable braille display using electroactive polymers or heated wax rather than mechanical pins to raise braille dots on a display. Though not inherently expensive, due to the small scale of production they have not been shown to be economical.
The end product is to display 36 braille characters at a time on a 5 in × 2 in (127 mm × 51 mm) interface [note 1] with an intended retail price around US$100. [3] With existing braille display devices priced in the range of $1,500 to $2,500, Tactile has been characterized as a potential "quantum leap forward for the blind community."
It can also be read on a refreshable braille display either as a stand-alone electronic device or connected to a computer or smartphone. Refreshable braille displays convert what is visually shown on a computer or smartphone screen into braille through a series of pins that rise and fall to form braille symbols.
Job Access With Speech (JAWS) is a computer screen reader program for Microsoft Windows that allows blind and visually impaired users to read the screen either with a text-to-speech output or by a refreshable Braille display. JAWS is produced by the Blind and Low Vision Group of Freedom Scientific.
The user can switch between controls (such as buttons) available on the screen and the captions and control contents will be read aloud and/or shown on a refreshable braille display. Screen readers can also communicate information on menus, controls, and other visual constructs to permit blind users to interact with these constructs.
Many visually impaired users use electronic portable note-taking devices that allow keyboard entry in braille using the 6-key layout of the Perkins Brailler and output in synthesized speech and/or a one or two-line refreshable braille display consisting of tiny pins made of metal and plastic.
