Definitions

  • the present invention relates to the field of tactile relief symbols - Lunas spectrum- that can be recognized by the blind or the visually impaired persons by tracing with their fingertips, and is directed particularly to tactile relief symbols for identifying color.
  • a patent to Wills, et al., U.S. Pat. No. 4,404,-764, discloses the use of Braille on picture cards which identify in word form the depictions on the card. For example, if a sail boat were pictured, the Braille symbols for sail boat would be raised on the card at the location of the pictured sail boat. This patent does not claim or disclose the use of symbols for color other than the Braille letters spelling a color.
  • U.S. Pat. No. 4,650,421 issued to Anczurowski discloses the use of crosshatching, which may be either raised using the xerographic process or embossed on a substrate, to identify color.
  • a first color may be represented by a series of horizontal lines
  • a second color will be a series of parallel lines angled at 60 DEG and 120 DEG with the lines of the first primary color.
  • a third primary color will be represented by a third series of parallel lines oriented so that it maintains a 60 DEG or 120 DEG angle with both the first and the second series of lines.
  • Combining the symbols for two or more of the colors would present a symbol comprising crosshatched lines to represent a new color, the new color formed by mixing the colors represented by the symbols together.
  • U.S. Pat. Appl. No. 2013139952 (A1) published on 06-06-2013 relates to a system and method of tactile relief stickers, decals or moldings to indicate object characteristics, for example to indicate object color.
  • the system can include a plurality of stickers.
  • Each sticker can have a first surface with a relief texture and a second surface opposite the first surface.
  • Each sticker can also have a relief texture corresponding to a color according to a predetermined correspondence of one texture to one color.
  • the second surface can have an adhesive applied thereto.
  • U.S. Pat. No. 5,286,204, issued to TOUCH BOOKS INC discloses tactile symbols for color recognition by blind or visually impaired persons comprising a surface above which a color symbol is raised substantially parallel to the first surface. The raised surface of the unitary symbol is continuous such that persons may identify the symbol by touch.
  • U.S. Pat. No. 5,286,204 and many other published patent documents implement geometrical shapes as tactile symbols associated to particular color. Use of geometrical shapes is limited to certain number of colors or their combinations. Further such system is rather complicated in marking color composed from combination of three primary colors and for instance black color. A crosshatching system as disclosed in U.S. Pat. No. 4,650,421 would dominate on any substrate losing the shape and form of the marked elements, particularly in case of combination of more colors such as CMYK color system.
  • Color is widely used within our language as a means of communicating not only the colors of objects but as coding on maps, charts and other visual displays.
  • tactile relief symbols associated to the wide color range system is intended for the blind or the visually impaired, and persons who are color blind is developed.
  • Technical problem solved by the present invention is enabling creating of tactile relief symbols intended for the blind or visually impaired persons which, in contrary to the solutions presented in prior art, provides tactile relief symbols of broad range of hue.

  • the present invention relates to tactile relief symbols for color recognition intended for the blind or the visually impaired, and persons who are color blind.
  • the primary element of tactile relief symbols is embossed dot where a series of authentic codes have not any similarity with the Braille letters. The only possible similarity can happen if the labeling dye implementing dots where dots are of the same size as in the Braille alphabet, but they are generally smaller. Depending on the context in which they are used can be the same size as the letters and dots for the blind but it cannot be increased because expressiveness of the tactile relief symbol is discolored. Spatial area/surface of the label is undefined. Although in this application tactile relief symbols are shown in squares, it is not defined by the rules of the system.
  • tactile relief symbols are formed into an area/surface upon which a color representation is desired. This surface defines a first plane or base.
  • the tactile relief symbol creates a second generally planar surface when it is embossed into the first surface. That is, within the peripheral boundaries of each tactile symbol, each raised surface is unitary. The embossing or other similar process raises this second surface as a second plane above and substantially parallel to the first plane.
  • This unitary raised second surface can be detected by blind or visually impaired persons through the sense of touch, permitting them to identify the color which the tactile relief symbol represents.
  • the fundaments of all tactile relief symbols for color recognition constitutes five basic marks. These are the marks of the three basic chromatic colors in the art of blue, yellow and red, and the marks for black and white. Combining tactile relief symbols of these basic marks i.e. by their mutual "combining" other "colors marks” are obtained, namely tactile relief symbols indicating secondary and tertiary colors.

Abstract

La présente invention concerne des symboles de couleurs tactiles en relief, ou marquage de couleurs, servant à coder des informations de couleurs transmises aux individus aveugles ou déficients visuels en touchant des symboles tactiles en relief qui indiquent de façon unique la couleur prédéterminée. Des symboles de couleurs tactiles en relief sont disposés sur la surface comportant une multiplicité de champs répartis, au moins un champ contenant un symbole tactile en relief porteur desdites informations concernant la couleur, et ledit champ contenant un symbole tactile en relief qui identifie de façon unique une couleur primaire, des couleurs secondaires, des couleurs tertiaires et des couleurs issues du modèle de couleurs CMYK, la couleur blanche et noire, le degré de transparence et la luminosité. Un symbole tactile en relief est constitué par une série de points en saillie qui correspondent auxdites couleurs et/ou à leur combinaison mutuelle. Les symboles tactiles en relief indiquant des couleurs secondaires constituent une combinaison mutuelle du motif de points en saillie des symboles tactiles en relief indiquant des couleurs primaires RYB, et les symboles tactiles en relief indiquant des couleurs tertiaires constituent une combinaison mutuelle du motif de points en saillie des symboles tactiles en relief indiquant des couleurs primaires RYB et secondaires. En outre, le symbole tactile en relief de couleur se traduisant par le mélange de deux couleurs est disposé dans un, deux ou quatre champs disposés sur ladite surface, le symbole tactile en relief de couleur se traduisant par le mélange de trois couleurs est disposé dans trois ou six champs disposés sur ladite surface, et le symbole tactile en relief de couleur se traduisant par le mélange de quatre couleurs, ou modèle de couleurs CMYK, est disposé dans quatre ou huit champs disposés sur ladite surface. Pour l'étiquetage des couleurs sont utilisés des points en saillie, disposés sur une surface contenant des informations de couleur transmises aux individus aveugles ou déficients visuels en touchant des symboles tactiles en relief, les points étant de la même taille ou plus petits que ceux utilisés dans l'écriture Braille. Les symboles tactiles en relief peuvent être appliqués à du papier, à des étiquettes adhésives, à du tissu, du métal, du bois, du plastique et d'autres matériaux, ou à des combinaisons de ceux-ci. La présente invention permet son utilisation dans des albums à colorier pour enfants, des jouets, ainsi que des marques ou étiquettes pour la couleur d'un vêtement, et en particulier dans l'utilisation d'objets pour l'utilisation desquels les couleurs sont importantes, etc.
