Samuel Gridley Howe, the first director of the New England Asylum for the Blind (now Perkins School for the Blind), studied tactile printing systems in Europe and developed his own system of raised type called Boston line letter. Howe's system was similar to raised letters designed by James Gall in Edinburgh, Scotland, in the 1820s. [1] In 1835 Howe printed Acts of the Apostles , the first book produced in Boston line letter. The letterforms were an angular modification of Roman letters and had no capital letters. The first books embossed at the American Printing House for the Blind in 1866 were in Boston line letter.
By 1868, N.B. Kneass, Jr., a printer in Philadelphia, had adapted what became known as a "combined system" which used the lower case forms of Boston line letter and capital letters from a rival tactile system known as Philadelphia Line. [2] Until replaced by dot systems this hybrid form of raised letters was the predominant embossed type for blind people in the United States and the choice of most of the schools.
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.
Louis Braille was a French educator and the inventor of a reading and writing system, named braille after him, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day.
Samuel Gridley Howe was an American physician, abolitionist, and advocate of education for the blind. He organized and was the first director of the Perkins Institution. In 1824 he had gone to Greece to serve in the revolution as a surgeon; he also commanded troops. He arranged for support for refugees and brought many Greek children back to Boston with him for their education.
Perkins School for the Blind, in Watertown, Massachusetts, was founded in 1829 and is the oldest school for the blind in the United States. It has also been known as the Perkins Institution for the Blind.
The Moon System of Embossed Reading is a writing system for the blind, using embossed symbols mostly derived from the Latin script. It is claimed by its supporters to be easier to understand than braille, though it is mainly used by people who have lost their sight as adults, and thus already have knowledge of the shapes of letters.
The subject of blindness and education has included evolving approaches and public perceptions of how best to address the special needs of blind students. The practice of institutionalizing the blind in asylums has a history extending back over a thousand years, but it was not until the 18th century that authorities created schools for them where blind children, particularly those more privileged, were usually educated in such specialized settings. These institutions provided simple vocational and adaptive training, as well as grounding in academic subjects offered through alternative formats. Literature, for example, was being made available to blind students by way of embossed Roman letters.
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.
Tactile signing is a common means of communication used by people with deafblindness. It is based on a sign language or another system of manual communication.
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.
Laura Dewey Lynn Bridgman was the first deaf-blind American child to gain a significant education in the English language, twenty years before the more famous Helen Keller; Laura's friend Anne Sullivan became Helen Keller's aide. Bridgman was left deaf-blind at the age of two after contracting scarlet fever. She was educated at the Perkins Institution for the Blind where, under the direction of Samuel Gridley Howe, she learned to read and communicate using Braille and the manual alphabet developed by Charles-Michel de l'Épée.
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 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.
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 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.
Decapoint, or raphigraphy, was a tactile form of the Latin script invented by Louis Braille as a system that could be used by both the blind and sighted. It was published in 1839. Letters retained their linear form, and so were legible without training to the sighted, but the lines were composed of embossed dots like those used in braille. Each letter contained ten dots in the height and different dots in the width to produce the graphic form of print.
A cecogram, also known as literature for the blind, is a letter or a parcel that contains documents or items intended for visually impaired persons. Cecograms can be sent or received by such persons, as well as by organisations that provide assistance to the visually impaired. Cecograms are either partially or entirely exempt from postage.
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.
