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.
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid.
Louis Braille was a French educator and the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day.
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.
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers, speakers, headphones, projectors, GPS devices, optical mark readers, and braille readers.
Deafblindness is the condition of little or no useful hearing and little or no useful sight. Different degrees of vision loss and auditory loss occur within each individual. Because of this inherent diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual-modality deprivation, to improve their ability to live independently. In 1994, an estimated 35,000–40,000 United States residents were medically deafblind. Helen Keller was a well-known example of a deafblind individual. To further her lifelong mission to help the deafblind community to expand its horizons and gain opportunities, the Helen Keller National Center for Deaf-Blind Youths and Adults, with a residential training program in Sands Point, New York, was established in 1967 by an act of Congress.
The Optacon is an electromechanical device that enables blind people to read printed material that has not been transcribed into Braille. The device consists of two parts: a scanner which the user runs over the material to be read, and a finger pad which translates the words into vibrations felt on the finger tips. The Optacon was conceived by John Linvill, a professor of Electrical Engineering at Stanford University, and developed with researchers at Stanford Research Institute. Telesensory Systems manufactured the device from 1971 until it was discontinued in 1996. Although effective once mastered, it was expensive and took many hours of training to reach competency. In 2005, TSI suddenly shut down. Employees were "walked out" of the building and lost accrued vacation time, medical insurance, and all benefits. Customers could not buy new machines or get existing machines fixed. Some work was done by other companies but no device with the versatility of the Optacon had been developed as of 2007. Many blind people continue to use their Optacons to this day. The Optacon offers capabilities that no other device offers including the ability to see a printed page or computer screen as it truly appears including drawings, typefaces, and specialized text layouts.
Charles Barbier de la Serre was the inventor of several forms of shorthand and alternative means of writing, one of which became the inspiration for Braille.
Tactile graphics, including tactile pictures, tactile diagrams, tactile maps, and tactile graphs, are images that use raised surfaces so that a visually impaired person can feel them. They are used to convey non-textual information such as maps, paintings, graphs and diagrams.
A braille translator is a software program that translates electronic text into braille and sends it to a braille peripheral, such as a braille embosser. 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, has complex rules for capitalization, emphasis, punctuation, typographic symbols, and page formatting.
A tactile alphabet is a system for writing material that the blind can read by touch. While currently the Braille system is the most popular and some materials have been prepared in Moon type, historically, many other tactile alphabets have existed:
The slate and stylus are tools used by blind people to write text that they can read without assistance. Invented by Charles Barbier as the tool for writing letters that could be read by touch, the slate and stylus allow for a quick, easy, convenient and constant method of making embossed printing for Braille character encoding. Prior methods of making raised printing for the blind required a movable type printing press.
Telesensory Systems, Inc. (TSI) was an American corporation that invented, designed, manufactured, and distributed technological aids for blind and low vision persons. TSI's products helped visually impaired people work independently with computers and with ordinary printed materials.
The American Printing House for the Blind (APH) is an American non-for-profit corporation in Louisville, Kentucky, promoting independent living for people who are blind and visually impaired. For over 150 years APH has created unique products and services to support all aspects of daily life without sight.
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:
Boston line letter was a tactile writing system created by Samuel Gridley Howe in 1835, a popular precursor to the now-standardized braille.
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.
James Morrison Heady was an American deafblind author. Heady published multiple volumes of children's books and poetry and was frequently referred to by the contemporary press as the "Blind Bard of Kentucky". He was one of the first advocates for books for the blind in the United States and he invented several devices to facilitate communication and improve quality of life for deaf and blind people.
Joshua A. Miele is an American research scientist who specializes in accessible technology design. Since 2019, Miele has been Principal Accessibility Researcher at Amazon Lab126, a subsidiary of Amazon that works on hardware products. Miele previously conducted research on tactile graphics and auditory displays at the Smith-Kettlewell Eye Research Institute in California for fifteen years. He has been blind since early childhood.
