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 to New York Point, the speed of reading braille, the large amount of written material available in English Braille compared to 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. ==Alphabet== New York Point is not supported by Unicode, as of version 6.3. In the charts below, the first row of NYP are graphic images, and the second row are braille cells turned on their side. Older browsers may not support the latter.〔NYP letters should only be as wide as their number of dots. However, since 2×3 braille cells are substituted for New York Point in the second row of their table, the one-dot-wide letters ''e, i,'' and ''t'' are wrongly shown as being as wide as others. The same inaccuracy occurs with the nine, zero, comma, and semicolon in the number and punctuation tables. The top row gives the proper widths.〕 Like braille, there are contractions: single letters in NYP that correspond to sequences of letter in print, and sequences in NYP as well when capitalized.〔''Catholic Encyclopedia'', (Education of the Blind )〕 Capitals are all 2×4 (8-dot blocks). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New York Point」の詳細全文を読む スポンサード リンク
