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.
Some e-books are produced simultaneously with the production of a printed format, as described in electronic publishing.
Braille books were initially written in paper, with Perkins Brailler typewriter, a machine invented in 1951, and improved in 2008, another way of produce braille books was with braille printers or embossers. In 2011 David S. Morgan produced the first SMART Brailler machine, with added text to speech function and allowed digital capture of data entered.
In 1960 Robert Mann, a teacher in MIT, wrote DOTSYS, a software that allowed automatic braille translation, and another group created an embossing device called "M.I.T. Braillemboss.". 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. [1] [2] [3] Braille translators allowed the automatic creation of braille text or books from an script into Braille scripture without the need of typing braille books in braille typewriters, but still needed embossers to produce books, this last step is not necessary when the e-book is read in a braille e-book.

A Korean concept design published in 2009 by Yanko Design attracted attention. [4] [5] [6] A British prototype design called "Anagraphs" was created in 2013, [7] but funding from the European Union ran out before it could be brought to production. [8]
A braille ebook/tablet was slated to be released for purchase in the 4th quarter of 2016 by the Austrian company Blitab. It was expected to be priced under US$3000[ needs update ]. As of February 2019 [update] the company was inviting people to sign up as a "Tester", with the explanation, "Become one of the first to touch and feel the future of large scale tactile Braille displays." [9]
In 2018, the German company Metec introduced the Braille E-Book, which, unlike its predecessors, has a field size of 120 x 97 mm, which can accommodate eight lines of 16 characters each. This device allows blind users to study graphs and geographical maps in a tactile way. The cost of the device is €13,800 (in 2019). [10] Since that time it has a couple of improvements including the display size, now it reaches 260 x 150 mm.
In 2019, Orbit Research together with American Printing House for the Blind released the braiile e-book Graphiti, which allows blind to explore graphical information. 2,400 points that rise to different heights are capable of transmitting topographic maps and other graphic elements such as shadows and color. The device also includes an eight-key braille keyboard for text entry. The cost of the device is $24,666 (in 2021). [11]
In 2020, engineering startup 4Blind, Inc. from Boston created the tactile e-book called Braille Pad. This is an 8-inch tablet (contains 3249 tactile pixels) with a built-in camera, which gives access to any graphic images (maps, graphs, etc.), and also allows the user to take photos with instant tactile transmission. [12]
Braille is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. 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.
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 refreshable braille displays.
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.
The Perkins Brailler is a "braille typewriter" with a key corresponding to each of the six dots of the braille code, a space key, a backspace key, and a line space key. Like a manual typewriter, it has two side knobs to advance paper through the machine and a carriage return lever above the keys. The rollers that hold and advance the paper have grooves designed to avoid crushing the raised dots the brailler creates.
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 equipment which converts information 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, thus making the deafblind community unique with many types of deafblindness involved. 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.
An electroactive polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaining large forces.
The Museum of the American Printing House for the Blind opened in 1994 and is located in Louisville, Kentucky. The museum tells the story of the international history of the education of people who are blind, and how the American Printing House for the Blind has contributed to that history. Exhibits focus on tactile systems, writing devices, braille production, orientation and mobility, educational aids and early schools for the blind. It is located on the second floor of the company's original 1883 factory building.
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 a script into braille and sends it to a braille embosser, which produces a hard copy of the original print text. Only the script is transformed, not the language.
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.
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.
Braille technology is assistive technology which allows blind or visually impaired people to do common tasks such as writing, browsing the Internet, typing in Braille and printing in text, engaging in chat, downloading files, 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 sighted classmates and allows them take courses online. It enables professionals to do their jobs and teachers to lecture using hardware and software applications. The advances of Braille technology are meaningful because blind people can access more texts, books and libraries and it also facilitates the printing of Braille texts.
Accessible publishing is an approach to publishing and book design whereby books and other texts are made available in alternative formats designed to aid or replace the reading process. It is particularly relevant for people who are blind, visually impaired or otherwise print disabled.
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.
A BrailleNote is a computer made by HumanWare for persons with visual impairments. It has either a braille keyboard or a Qwerty Keyboard, a speech synthesizer, and a 32- 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.
Tactile is a real-time text-to-braille translation device currently under development at the Massachusetts Institute of Technology. It was conceived by a team of undergraduate students, competing as "Team 100% Enthusiasm", during a 15-hour MIT "hackathon". The device is slid over printed text and a camera captures images of the words and sends them to a microcontroller. The information moves the pins up and down, translating the text into Braille. Once on the market it is hoped to be much cheaper than existing devices.
