New York Point
New York Point (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. (Letters of one through four pairs, each with two dots, would be ⟨:⟩ ⟨::⟩ ⟨:::⟩ ⟨::::⟩.) The most common letters are written with the fewest points, a strategy also employed by the competing American Braille.

Capital letters were cumbersome in New York Point, each being four dots wide, and so were not generally used. Likewise, the four-dot-wide hyphen and apostrophe were generally omitted. When capitals, hyphens, or apostrophes were used, they sometimes caused legibility problems, and a separate capital sign was never agreed upon. According to Helen Keller, this caused literacy problems among blind children, and was one of the chief arguments against New York Point and in favor of one of the braille alphabets.
New York Point competed with the American Braille alphabet, which consisted of fixed cells two points wide and three high. Books written in embossed alphabets like braille are quite bulky, and New York Point's system of two horizontal lines of dots was an advantage over the three lines required for braille; the principle of writing the most common letters with the fewest dots was likewise an advantage of New York Point and American Braille over English Braille.
Wait advocated the New York System as more logical than either the American Braille or the English Braille alphabets, and the three scripts competed in what was known as the War of the Dots. Around 1916, agreement settled on English Braille standardized to French Braille letter order, chiefly because of the superior punctuation compared with New York Point, the speed of reading braille, the large amount of written material available in English Braille compared with American Braille, and the international accessibility offered by following French alphabetical order.
Wait also invented the "Kleidograph", a typewriter with twelve keys for embossing New York Point on paper, and the "Stereograph", for creating metal plates to be used in printing.
