Braille translator

Last updated

A braille translator is a software program that translates electronic text (such as an MS-Word file) into braille and sends it to a braille peripheral, such as a braille embosser (which produces a hard copy of the newly created braille). Typically, each language needs its own braille translator. Despite the use of the word translator, there is no language translation. Even in the simplest situation, such as Dutch braille, [1] has complex rules for capitalization, emphasis, punctuation, typographic symbols, and page formatting.

Description

For the purposes of this article, the word "inkprint" means text prepared for reading by the eye, whether printed, displayed on a screen, or stored in a computer; "braille" means text prepared for reading by the finger, whether brailled, displayed on an electronic device, or stored in a computer.

Braille translation software or embedded hardware converts inkprint into braille or braille into inkprint. Usually, someone has inkprint in a word processor file or at an URL and wants braille. The braille could be sent to a braille embosser to produce physical braille or to an braille notetaker. Another circumstance is that someone has braille in an electronic braille notetaker that they want to produce in inkprint to be shared with someone who does not read braille.

Braille translation software is usually classified as assistive technology since the action of the software provides braille for a blind person. Braille translators can be run by people with or without sight.

A braille translator can run on a smartphone, [2] personal computer, network server, [3] or (historically) larger mini-computers or mainframes of larger institutions.

Some languages use uncontracted braille, where each letter uses a specific braille character. Uncontracted braille requires manipulation of capitalization, emphasis, numbers, and punctuation. Some languages use contracted braille, where the rules for various braille abbreviations are quite complex. For example, in contracted English braille, the word think (5 letters) is rendered as 3 characters: ⠹⠢⠅ (th)(in)k. The use or non-use of these contractions is related to pronunciation. For example, the "th" sign is used in think, but not pothole. Unless properly programmed, a computer might make a mistake that no person would make, such as using the contraction for mother in the word chemotherapy. The most difficult part of producing braille is making the decision of when and when not to use contractions. When people make these decisions, it is braille transcription; when computers make these decisions, it is braille translation.

History

The first practical application of computer translation and production of braille used mainframe computers at the American Printing House for the Blind of Louisville, Kentucky. [4] [5]

During the 1960s, there was an MIT project to automate the production of braille. Robert Mann wrote and supervised software for braille translation called DOTSYS, while another group created an embossing device which became known as the "M.I.T. Braillemboss.". Eventually, MIT outsourced the software work to Mitre Corporation. [6] The Mitre Corporation team of Robert Gildea, Jonathan Millen, Reid Gerhart and Joseph Sullivan (now president of Duxbury Systems) developed DOTSYS III, the first braille translator written in a portable programming language. DOTSYS III was developed for the Atlanta Public Schools as a public domain program. [7]

At the first International Workshop on Computerized Braille Production, held in Muenster, Germany, March 1973, many braille-translation projects from around the world were described. [8]

An archive of documents on the history of braille, braille translation, and some braille devices is maintained by Duxbury Systems. [9]

<span class="mw-page-title-main">Assistive technology</span> Assistive devices for people with disabilities

Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, disabled people have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation", "security and control", and a greater chance to "reduce institutional costs without significantly increasing household expenses." In schools, assistive technology can be critical in allowing students with disabilities to access the general education curriculum. Students who experience challenges writing or keyboarding, for example, can use voice recognition software instead. Assistive technologies assist people who are recovering from strokes and people who have sustained injuries that affect their daily tasks.

Braille is a tactile writing system used by people who are visually impaired. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser.

New York Point is a braille-like system of tactile writing for the blind invented by William Bell Wait (1839–1916), a teacher in the New York Institute for the Education of the Blind. The system used one to four pairs of points set side by side, each containing one or two dots. The most common letters are written with the fewest points, a strategy also employed by the competing American Braille.

William Bell Wait (1839–1916) was a teacher in the New York Institute for the Education of the Blind who invented New York Point, a system of writing for the blind that was adopted widely in the United States before the braille system was universally adopted there. Wait also applied the New York Point principles to adapt them for use in over 20 languages, created a form of New York Point to notate music, and invented a number of devices to better type and print embossed material for the visually impaired.

Braille ASCII is a subset of the ASCII character set which uses 64 of the printable ASCII characters to represent all possible dot combinations in six-dot braille. It was developed around 1969 and, despite originally being known as North American Braille ASCII, it is now used internationally.

Braille technology is assistive technology which allows blind or visually impaired people to read, write, or manipulate braille electronically. This technology allows users to do common tasks such as writing, browsing the Internet, typing in Braille and printing in text, engaging in chat, downloading files and music, using electronic mail, burning music, and reading documents. It also allows blind or visually impaired students to complete all assignments in school as the rest of their sighted classmates and allows them to take courses online. It enables professionals to do their jobs and teachers to lecture using hardware and software applications. The advances in Braille technology are meaningful because blind people can access more texts, books, and libraries, and it also facilitates the printing of Braille texts.

The Braille Challenge is an annual two-stage Braille literacy competition designed to motivate blind students to emphasize their study of Braille. The program parallels with the importance and educational purpose of a spelling bee for sighted children. Braille is a reading and writing method that breaks language into a code of raised dots. There are three grades of braille:
