Description

  The present invention relates to an information providing tool that provides information to a color blind person using a plurality of color elements visually. More specifically, the present invention relates to a color blind person (using a plurality of color elements visually) The present invention relates to an information providing tool that provides traffic route information that can identify red-green color vision abnormalities and that does not give a sense of discomfort to people with normal color vision.

  Many public institutions are making various barrier-free efforts. Typical examples of barrier-free facilities include a passage fitted with Braille tiles, but in recent years, part of the stairs has been ramped and elevators have been actively introduced. ing.

Various ideas have also been applied to the signboard explaining the subway network in a large city. The number of subways in a large city is very large, and it is very difficult to convey information such as station names and route names to the unspecified number of people using only letters. For this reason, the route map of a subway in a large city is color-coded for each route and the route is displayed.
Such a color coding method has been used for a long time, and currently, the line displayed in red in the subway map of Tokyo indicates "Marunouchi Line", and the line displayed in yellow indicates "Ginza Line" The line displayed in purple indicates the “Hanzomon Line”, and the color type strongly demonstrates the discrimination with respect to the route type.
If the color type has reached a level of discrimination that gives certain information to an unspecified number of people, it is not possible to change such a color type during the barrier-free approach. It is expected to cause great confusion for a specific majority.

  Patent Document 1 proposes a design method that allows a color blind person to identify a difference between color elements and does not give a sense of discomfort to a person with normal color vision.

  First, the type of color blindness will be described. The human eye has a weight body that senses red (R), which is the three primary colors, a weight body that senses green (G), and a weight body that senses blue (B). Of these three types of pyramidal cells, depending on which of the spindles changes, it is further classified into a first color vision abnormality, a second color vision abnormality, and a third color vision abnormality. The color recognition of the first color vision abnormality and the second color vision abnormality is relatively close, and is collectively called “red-green color vision abnormality”. The third color vision abnormality is rare.

According to Patent Document 1, a person with color blindness does not cause inconvenience to both a person with color blindness and a person with normal color blindness using a color change pattern that is considered to have better recognition ability than a person with normal color blindness. Two methods are proposed.
The first method of Patent Document 1 is a method for adjusting saturation, brightness, and hue. The second method is a method of adjusting saturation and lightness. The third method is a method of increasing or decreasing the yellow color.

JP 2007-240508 A

  According to the first method of Patent Document 1, it is possible to create a color arrangement pattern that is easy for a color blind person to identify by adjusting all of saturation, lightness, and hue. Although this method is considered effective when creating a new design, it is not suitable for application to a well-known existing design such as a subway route map.

  The second method of Patent Document 1 is a method in which color-blindness is adjusted so that color-blind persons can identify differences between color elements, and can be applied when a large color change is not preferable. However, the adjustment of color element density alone is not sufficient to overcome the difficulty of identifying differences between color elements, and it is necessary to combine techniques such as hatching and separation.

  The third method of Patent Document 1 is a method that increases or decreases the yellow component, adjusts the brightness and saturation, and enables a person with color blindness to identify a difference between color elements. This method can be applied only in a subtractive color mixing field such as a color print, and cannot be applied in an additive color mixing field. Further, Patent Document 1 does not disclose how much yellow component should be increased or decreased, and it is necessary to go through trial and error in order to obtain a desired result.

  The present invention has been made in view of the above circumstances, and provides traffic route information that can visually identify a person with abnormal color blindness using a plurality of color elements visually for the person with abnormal red-green color vision. The purpose is to provide an information providing tool that does not give a sense of incongruity to people with normal color vision, and it does not require trial and error and makes effective color adjustments for specific color combinations that are difficult for color blind people to identify.

The color element given to each pattern in the inside should be interpreted as an actual color.

FIG. 1 is a simplified diagram of a subway map of Tokyo used to describe one embodiment of the present invention. Different color elements are assigned to each route shown in the subway route map. Some of these color elements have been used for a long period of time, and as a result, there are some color elements that are well known to the extent that it is possible to determine which route is being displayed simply by looking at the color elements. For example, a person who commutes to Tokyo can recognize that “Marunouchi Line” indicates a red line.
Table 1 below shows the relationship between patterns and color elements in FIG. The color elements assigned to each route refer to the Tokyo Metro route map and the Toei subway route map widely distributed through the Internet.

  The present invention relates to an information providing tool in which a plurality of types of color elements are arranged next to each other and provide information by a color difference between the color elements. In the example shown in FIG. 1, each route is color-coded by a plurality of types of color elements, and lines represented by different color elements intersect with each other. However, the present invention is not limited to those intersecting with each other, and different colors. The present invention is also applied to a form in which seed lines are adjacent to each other and extend in parallel, or a form in which color regions of arbitrary shapes represented by different color types are arranged next to each other.

In addition, a plurality of rectangular strips whose RGB values were changed within a range that the color vision normal person determined to be cocoon color were extended in the horizontal direction, and these rectangular strips were arranged in the vertical direction. These orange rectangular strips and cocoon-colored rectangular strips were crossed in a matrix form to create a color matrix diagram shown in FIG.
Using the color matrix diagram created in this way, a test was conducted to determine whether type 1 2-color vision and type 2 2-color vision can be identified, or whether identification is difficult. In addition, the method similar to what was demonstrated in relation to Table 2 and Table 3 was used as a numerical method for evaluation.

Further, the red and brown color matrix diagrams and the red and green color matrix diagrams are also created in the same manner as the color matrix diagram shown in FIG. An evaluation test was performed.
