Six principal systems of embossed type in use c. 1900: Haüy, Gall, Howe, Moon, Braille, Wait
Atactile alphabet is a system for writing material that the blind can read by touch. While currently theBraille system is the most popular and some materials have been prepared inMoon type, historically, many other tactile alphabets have existed:
Jacob Snider, Jr.'s system, using rounded letters similar to Haüy's system, which was used in a publication of theGospel of Mark in 1834, the first embossed book in theUnited States.
Samuel Gridley Howe'sBoston Line using lowercase angular letters, influenced by Gall's system but more closely resembling standard Roman letters
William Chapin (also at the Pennsylvania Institution)'s system, combining the lowercase letters of the Boston Line with the capitals of the Philadelphia Line, forming the "combined system" (used by 1868 in books printed byN. B. Kneass, Jr.)
Elia Chepaitis's ELIA Frame tactile alphabet/font system includes the major characteristics of the Roman alphabet letter within a frame. The frame denotes where the letter begins and ends and allows for systematic exploration. The use of the Roman alphabet's features in the design helps previously sighted people learn it. And its similarities to standard Roman fonts helps sighted caregivers to learn and share the alphabet with people who have a visual impairment.[1]
