Abstract

L'invention concerne un code dessiné à la main qui est un produit de code bidimensionnel qui réalise un stockage de données d'information dans une structure de motif ou de caractère, de référence, ou dessiné à la main, et comprend un produit de code dessiné à la main, un générateur de code, un décodeur et un composant de système. Au moyen d'une telle technologie de code dessiné à la main, des informations sont stockées précisément dans un contour de caractère ou une structure de motif, dessiné à la main ou spécifié, sans que ne soient compromises la caractéristique globale et l'expression originale d'un motif ou d'un caractère original, ce qui permet de conserver les caractéristiques culturelles et artistiques du motif original. Par conséquent, il est possible d'utiliser davantage de techniques de stockage et lecture d'informations détaillées, pour l'expression de la signification morphologique de motifs ou de caractères, permettant aux utilisateurs de concevoir des échantillons de code par eux-mêmes, de telle sorte que la génération et la fabrication de code deviennent plus personnalisées, et que des produits de code de motif et des domaines d'application sont enrichis, y compris des signatures personnelles, des marques de commerce d'entreprises, et d'autres motifs de caractère. Le code peut être lu directement, à la fois en ligne et hors ligne. La technologie de code de motif donne une double caractéristique d'information à tous les motifs et caractères : une lecture manuelle et une lecture machine, de telle sorte que des informations de motif ou de caractère lues manuellement sont cohérentes avec des informations de motif lues par une machine sur le même support.
