  • the semi-braille of some Japanese letters is encoded as follows.
  • the Braille definition of the letter V in German is different from English, which is 1236 points, so its semi-brace code is 73.

Abstract

L'invention concerne un procédé efficace d'entrée à codage numérique en braille avec demi-carrés. L'invention fait appel à un clavier numérique comme clavier d'entrée et consiste à séparer chaque caractère braille carré en un demi-carré gauche et un demi-carré droit, puis à utiliser respectivement une touche numérique pour représenter le code des demi-carrés gauche et droit, à utiliser le code à deux bits formé à partir des demi-carrés gauche et droit pour définir le code d'un caractère braille carré, à utiliser une définition braille pour définir le codage numérique pour tous les types de symboles et d'autres caractères, et à utiliser les touches numériques pour entrer tous les types de caractères de langage et de symboles, ou produire en sortie les caractères braille sur une machine à écrire en braille spéciale. Le procédé d'entrée de la présente invention présente une haute efficacité et est facile à apprendre et à mettre en oeuvre pour un non-voyant du fait de la conservation de l'écriture braille. Par conséquent, la présente invention permet au non-voyant d'entrer tous les types de caractères de langage et de symboles sur un ordinateur, un téléphone à poussoirs, un téléphone mobile, un ordinateur de poche et tout autre clavier d'entrée numérique en vue d'un traitement de texte et d'une communication d'informations.
