[0003] [Patent Document 1] JP 2009-100312 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure provides techniques for indicating the color of an article taking into account color vision variability. [Means for solving the problem]

[0005] One aspect of the present disclosure is a tag attached to an article. The tag has at least one of a first region and a second region. The first region indicates the color of the article as perceived by a person with normal color vision in a manner perceivable by a person with color deficiency. The second region indicates the color of the article as perceived by a person with color deficiency in a manner perceivable by a person with normal color vision.

[0006] In this aspect, the color of an article perceived by a person with general color vision is displayed in a manner perceivable by a person with color weakness. Therefore, this tag allows a person with color weakness to recognize how an article looks to a person with general color vision. Alternatively, in this aspect, the color of an article perceived by a person with color weakness is displayed in a manner perceivable by a person with general color vision. Therefore, this tag allows a person with general color vision to recognize how an article looks to a person with color weakness. Therefore, this tag can display the color of an article taking color vision diversity into consideration.

[0007] Another aspect of the present disclosure is a method for providing an article. The method for providing an article includes a determining step, an attaching step, and a providing step. In the determining step, a tag is determined based on the color of the article. The tag has at least one of a first region that shows the color of the article as perceived by a person with normal color vision in a manner perceptible by a person with color deficiency, and a second region that shows the color of the article as perceived by a person with color deficiency in a manner perceptible by a person with normal color vision. In the attaching step, the tag determined in the determining step is attached to the article. In the providing step, an article to which the tag is attached is provided.

[0008] The method according to this aspect can use a tag having the above characteristics to indicate the color of an article while taking into account color vision variability. Effect of the Invention

[0011] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicated explanations will be omitted.

[0012] [Overview of color vision diversity] The concept of the present disclosure is to provide a technology for displaying colors taking into account color vision diversity. Color vision diversity refers to a situation in which people have different perceptions or discrimination of colors. People with different color vision have difficulty in having a common perception of colors. For this reason, it is important for people with different color vision to deepen their mutual understanding of color perception or discrimination.

[0013] There are five types of color vision: C type (Common), P type (Protanope), D type (Deuteranope), T type (Tritanope), and A type (Acromatic).

[0014] Type C is a group that has three types of cones: L cones, M cones, and S cones. L cones are photoreceptor cells that are highly sensitive to light in the long wavelength range, such as red. M cones are photoreceptor cells that are highly sensitive to light in the medium wavelength range, such as green. S cones are photoreceptor cells that are highly sensitive to light in the short wavelength range, such as blue. In the case of Japanese people, 95% of men and 99% of women belong to type C. Type C people are also said to have general color vision.

[0015] On the other hand, people with P, D, T, and A types are also called color-blind. P type is a group consisting of P type strong (Protanopia) who do not have L cones, and P type weak (Protanomaly) where the sensitivity of L cones is shifted and similar to that of M cones. D type is a group consisting of D type strong (Deuteranopia) who do not have M cones, and D type weak (Deuteranomaly) where the sensitivity of M cones is shifted and similar to that of L cones. T type is a group that does not have S cones. A type is a group that has only one type of cone or no cones at all. P type and D type make up the majority of color-blind people, and the proportion of T type and A type is extremely small.

[0016] As an example of the promotion of common perception or mutual understanding described above, the present disclosure provides physical tags that allow a person with color blindness to perceive colors as common color vision does, or vice versa. The tags may be designed to promote common perception or mutual understanding of colors between people with C, P, and D types. The present disclosure also provides examples of using colors on articles that are perceived the same by both people with common color vision and people with color blindness.

[0017] [Tag Overview] A tag is attached to an item and indicates information about the color of the item. The item may be, for example, clothing, fabric, furniture, small items, etc., and is not particularly limited as long as it is an object having color. Clothing generally refers to anything worn, including Western clothing, underwear, hats, scarves, gloves, footwear, etc. In the following, a case where the item is clothing will be described as an example. The tag being attached includes not only the tag being sewn directly onto the item, but also the tag being attached to the item with a string like a price tag. Alternatively, the tag being attached may be indirectly, that is, logically, linked to the item.

[0018] FIG. 1 is a diagram showing an example of a garment equipped with a tag according to an embodiment. As shown in FIG. 1, a tag 1 is attached to a garment 10. In the example shown in FIG. 1, the tag 1 is sewn to the lining of the garment 10. Another tag 11 may be sewn to the garment 10. The garment 10 has a color C1. The color C1 has a predetermined spectrum, and is perceived as a different color by people with normal color vision and people with color-blindness. The spectrum is a plot of the relationship between wavelength (nm) and reflectance (%).

[0019] Each of (A) to (E) of FIG. 2 is a diagram showing an example of a tag according to the embodiment. The tag 1 shown in (A) of FIG. 2 has a first region R1 and a second region R2. The first region R1 is a region for displaying information for color-blind people. The first region R1 includes information for color-blind people showing how a color C1 appears to a person with general color vision. As a more specific example, the first region R1 displays a figure of clothing having a first color E1. The first color E1 has a spectrum configured such that the response of the color vision system of a color-blind person who sees the first region R1 matches the response of the color vision system of a person with general color vision who sees the clothing 10. "The responses of both match" does not only mean that the difference between the responses of both is 0, but also means that it is equal to or less than a predetermined threshold. In other words, the match includes a predetermined approximate range, and the threshold can be determined by testing. The first region R1 allows a person with color-blindness to recognize how the clothing 10 appears to a person with general color vision. The first region R1 may additionally include characters, symbols, etc. indicating the first color E1. The first region R1 may be configured with characters, symbols, etc. indicating the first color E1 without including the first color E1. For example, the first region R1 may include only characters such as "red" and "blue" or only symbols such as "R" and "G."

[0020] The second region R2 is a region that displays information for people with general color vision. The second region R2 includes information that indicates to people with general color vision how a color C1 appears to a person with color vision deficiency. As a more specific example, the second region R2 displays a figure of clothing having a second color F1. The second color F1 has a spectrum configured such that the response of the color vision system of a person with general color vision who sees the second region R2 matches the response of the color vision system of a person with color vision deficiency who sees the clothing 10. "The responses of both match" does not only mean that the difference between the responses of both is zero, but also means that it is equal to or less than a predetermined threshold. In other words, the match includes a predetermined approximate range, and the threshold can be determined by testing. The second region R2 allows people with general color vision to recognize how the clothing 10 appears to a person with color vision deficiency. The second region R2 may additionally include characters, symbols, etc. indicating the second color F1. The second region R2 may be composed of characters, symbols, etc. indicating the second color F1 without including the second color F1. For example, the second region R2 may include only characters such as "red" and "blue" or may include only symbols such as "R" and "G."

[0021] The tag 1 only needs to have at least one of the first region R1 and the second region R2. For example, as shown in FIG. 2B, the tag 1A displays only information for color-blind people, so it can be said that the tag 1A has only the first region R1. The information displayed in the first region R1 may be displayed in various ways. For example, as shown in FIG. 2C, the tag 1B includes a plurality of colors E11 and E12 that can be perceived by color-blind people. The plurality of colors E11 and E12 are colors that become a first color E1 perceived by a person with normal color vision when mixed together. For example, when the first color E1 is pink, the color E11 can be white and the color E12 can be red. In this way, the colors displayed as the basis of the combination can be simplified (reduced to primary colors). Therefore, the tag 1B can display the first color E1 perceived by a person with normal color vision in a manner that is easy for a person with color-blindness to recognize.

[0022] Each of the multiple colors E11, E12 may be a color in which the difference between the response of the color vision system of a color-blind person and the response of the color vision system of a person with normal color vision falls within a predetermined range. In other words, each of the multiple colors E11, E12 is a color that can be perceived as approximately the same by both color-blind people and people with normal color vision. The predetermined range can be determined by testing. In the following disclosure, a color that can be perceived as approximately the same by both color-blind people and people with normal color vision is referred to as a universal color. By using universal colors, the tag 1B can allow people with normal color vision to understand the information for color-blind people written on the tag 1B.

[0023] The tag 1 may have only the second region R2. As shown in FIG. 2D, the tag 1C displays only information for people with normal color vision, so it can be said that the tag 1C has only the second region R2. The information displayed in the second region R2 may be displayed in various ways. For example, as shown in FIG. 2E, the tag 1D includes a plurality of colors F11 and F12 that can be perceived by people with normal color vision. The plurality of colors F11 and F12 are colors that become a second color F1 perceived by people with color weakness when mixed together. For example, when the second color F1 is sky blue, the color F11 can be white and the color F12 can be blue. In this way, the colors displayed as the basis of the combination are simplified (primary colors). Therefore, the tag 1D can display the second color F1 perceived by people with color weakness in a manner that is easy to recognize for people with normal color vision.

[0024] Each of the multiple colors F11, F12 may be a color in which the difference between the response of the color vision system of a color-blind person and the response of the color vision system of a person with normal color vision falls within a predetermined range. The predetermined range can be determined by testing. By using universal colors, the tag 1D can allow color-blind people to understand the information written on the tag 1D that is intended for people with normal color vision.

[0025] The multiple colors E11, E12 described using Fig. 2C and the multiple colors F11, F12 described using Fig. 2E are also applicable to the tag 1 shown in Fig. 2A. Thus, a total of six types of tags are exemplified: tag 1 having a first region R1 and a second region R2, a tag (not shown) that provides a display of a combination of multiple colors in tag 1, tag 1A having only the first region R1, tag 1B that provides a display of a combination of multiple colors in tag 1A, tag 1C having only the second region R2, and tag 1D that provides a display of a combination of multiple colors in tag 1C.

[0026] In order to obtain color information from the tag, a person attempting to perceive the color of the clothing 10 needs to know whether the tag includes the first region R1 or the second region R2, or whether the tag includes both regions. If the tag includes both regions, a person attempting to perceive the color of the clothing 10 needs to know which region is the first region R1 and which region is the second region R2. This information may be written on the tag, may be separately attached to the item as explanatory information, or may be made known by being posted in the sales area of ​​the item.

[0027] [Summary of how goods are provided] Fig. 3 is a flowchart showing an example of a method for providing an item. The method M1 shown in Fig. 3 includes a step of determining a tag (step S10), a step of attaching the tag (step S12), and a step of providing the item (step S14).

[0028] In the step of determining the tag (step S10), a device or a person determines the tag to be attached to the item based on the color of the item. First, the case where the device determines the tag will be described.

[0029] FIG. 4 is a diagram showing an example of the configuration of a tag determination device. The tag determination device 100 shown in FIG. 4 is composed of one computer or multiple computers connected to each other by a communication network. A computer generally includes a processor, a memory, a communication interface, an input device, and an output device as hardware devices. Examples of the processor include a CPU and a GPU. The memory includes a flash memory, a hard disk, and the like. The communication interface includes a network card or a wireless communication module. Examples of the input device include a keyboard, a pointing device, a touch panel, a microphone, a sensor, and a camera. Examples of the output device include a monitor, a touch panel, a head mounted display (HMD), and a speaker. The tag determination device 100 includes, as an example, a processor 101 and a memory 102. The memory 102 stores a tag table TB1 in advance.

[0030] Fig. 5 is a diagram showing an example of a tag table. The tag table TB1 shown in Fig. 5 is an example of a table in the case where the six types of tags described above are prepared for each color. As shown in Fig. 5, the tag table TB1 is a table that associates "color of item" with "tag identifier." The "tag identifier" is further associated with "information presentation target," "multiple color display," "color of first area," and "color of second area."

[0031] In the example shown in FIG. 5, "item color" indicates the color of the clothing 10. "tag identifier" is information that uniquely identifies the tag. "information presentation target" is information that indicates to whom the information displayed on the tag is intended. Here, it is divided into three categories: information for people with color blindness, information for people with normal color vision, and information for both. "Display of multiple colors" is information that indicates whether or not there is a mode in which a combination of multiple colors is displayed. "Color of first area" is the color displayed in the first area R1. "Color of second area" is the color displayed in the second area R2.

[0032] Next, the operation of the tag determination device 100 will be described. First, the processor 101 accepts color information of the clothing 10. The processor 101 may accept color information input by a user of the tag determination device 100, or may accept color information recognized by an image sensor capturing an image of the clothing 10. Next, the processor 101 refers to the tag table TB1 in the memory 102 and determines a tag based on the accepted color information. The processor 101 outputs the determined tag as tag determination information.

[0033] For example, when the processor 101 receives the color of the item "C1", the processor 101 refers to the tag table TB1 and acquires the tag identifiers "T1" to "T6" associated with the color of the item "C1". The processor 101 selects one tag identifier from the tag identifiers "T1" to "T6" and outputs it as tag determination information. For example, the processor 101 queries the user of the tag determination device 100 about "information presentation target" and "multiple color display", and selects one tag identifier based on the user's answer. For example, when the user answers that the information presentation target is "for color-blind people" and that the multiple color display is "no", the processor 101 selects the tag identifier "T3". As a result, the tag 1A shown in FIG. 2B is selected.

[0034] The processor 101 may select one tag identifier using the "information presentation target" and "multiple color display" input in advance by the user. The processor 101 may also randomly select one tag identifier. The above operation ends the tag determination step (step S10) shown in Fig. 3. When a person performs the tag determination step (step S10), for example, the tag table TB1 shown in Fig. 5 may be referenced to select a tag according to the color of the item.

[0035] When the step of determining the tag is completed, a step of attaching a tag (step S12) is executed. In the step of attaching a tag, a device or a person attaches the tag determined in step S10 to the clothing 10. When the step of attaching a tag is completed, a step of providing an item (step S14) is executed. In the step of providing an item, a device or a person provides the clothing 10 with the tag attached. Providing includes transporting, displaying, transferring, selling, etc.

[0036] This is the end of the flowchart shown in Fig. 3. By executing the flowchart shown in Fig. 3, a tag corresponding to the color of the item is attached to the item.

[0037] [Tag display color] The colors displayed in the first region R1 and the second region R2 are determined based on the color of the article. The configuration and operation of a device for determining the colors displayed in the first region R1 and the second region R2 will be outlined below. The color of the article is referred to as the base color, the color of the first region R1 as the first color, and the color of the second region R2 as the second color. The first color is a color having a spectrum configured such that the response of the color vision system of a color-blind person who sees the first region R1 matches the response of the color vision system of a person with general color vision who perceives the base color. The second color is a color having a spectrum configured such that the response of the color vision system of a person with general color vision who sees the second region R2 matches the response of the color vision system of a person with general color vision who perceives the base color.

[0038] FIG. 6 is a diagram showing an example of the configuration of a color conversion device. The color conversion device 200 shown in FIG. 6 is composed of one computer or a plurality of computers connected to each other via a communication network. The color conversion device 200 includes a processor 201 and a memory 202. The memory 202 stores in advance the cone sensitivity function of a person with normal color vision and the cone sensitivity function of a person with color weakness. The cone sensitivity function is also called a color vision system, and is the sensitivity characteristic of each of the L cones, M cones, and S cones, and indicates the relationship between wavelength and relative sensitivity. The cone sensitivity function outputs a response according to the shape of the input spectrum. The cone sensitivity function may be prepared for each type of color vision, and for example, a P-type cone sensitivity function and a D-type cone sensitivity function may be prepared.

[0039] The processor 201 inputs the spectrum of the base color in the visible light region. Then, the processor 201 obtains the responses (three numbers) of the L cone, the M cone, and the S cone based on the spectrum of the base color in the visible light region and the cone sensitivity function of the color-weak person stored in the memory 202. Next, the processor 201 obtains the responses (three numbers) of the L cone, the M cone, and the S cone based on the spectrum of the base color in the visible light region and the cone sensitivity function of the color-weak person stored in the memory 202. Then, the processor 201 repeats changing the shape of the spectrum of the base color and obtaining the corresponding response of the color-weak person so that the response of the color-weak person approaches (matches) the response of the color-weak person to the response of the color-weak person. This results in a spectrum in which the response of the color-weak person and the response of the color-weak person match. The color of the spectrum obtained in this way is the first color described above.

[0040] The spectrum of the second color can be determined in the same manner as the first color. That is, the processor 201 repeatedly changes the shape of the spectrum of the base color and obtains the corresponding response of the general color vision person so that the response of the general color vision person approaches (matches) the response of the color-blind person. This results in a spectrum in which the response of the general color vision person matches the response of the color-blind person. The color of the spectrum obtained in this manner is the above-mentioned second color.

[0041] Next, a universal color, which is a plurality of colors displayed in the first region R1 and the second region R2, will be described. The universal color can be generated based on two colors and a consideration ratio. The consideration ratio is the degree of consideration of color vision diversity, and is a numerical value within a range of 0% to 100%. The two colors are a color with a consideration ratio of 0% and a color with a consideration ratio of 100%. The color with a consideration ratio of 0% is a base color. The color with a consideration ratio of 100% is a color in which the response of the color vision system of a color-blind person coincides with the response of the color vision system of a person with normal color vision who perceives the base color, and is the above-mentioned first color. The processor 201 inputs the consideration ratio, linearly combines the spectrum of the base color (or a color obtained by changing the spectrum of the base color) and the spectrum of the first color according to the consideration ratio so as to obtain the input consideration ratio, and outputs a spectrum changed to correspond to the consideration ratio. As an example, the universal color can be generated with a consideration ratio of 20% or a value close to it. The processor 201 may output a spectrum changed to correspond to the consideration ratio in a different manner. For example, under the condition that the RGB of the base color is constant, the processor 201 prepares a color with a changed spectrum shape so that the response of a color-blind person approaches (matches) the response of a person with normal color vision. When creating a color with a larger consideration ratio than the prepared color, the processor 201 linearly combines the prepared color and a color with a consideration ratio of 100% according to the consideration ratio, and outputs a spectrum changed to correspond to the consideration ratio.

[0042] [Various embodiments] Various embodiments of a technology for indicating colors taking color vision diversity into consideration will be described. Each of Fig. 7(A) to Fig. 7(E) is a diagram showing an example of how to indicate colors in various embodiments. The tag 1 shown in Fig. 2(A) and the like is not limited to clothing 10, and can also be attached to furniture such as a sofa as shown in Fig. 7(A). Alternatively, the tag may be attached to small items such as stationery. This allows for a deeper mutual understanding between people with color-blindness and people with normal color vision regarding the colors of furniture or small items.

[0043] The first color shown in the present disclosure may be applied to clothing without using a tag. For example, as shown in FIG. 7B, the lining of a clothing item of color C1 may be the first color E1. This allows the colors of the front and back of a reversible garment to have a relationship, and deepens mutual understanding between color-blind people and people with normal color vision.

[0044] The universal color disclosed in this disclosure can be applied to various items. For example, as shown in FIG. 7C, the universal color UC1 may be used for the color of clothing. Alternatively, as shown in FIG. 7D, the universal colors UC1, UC2, and UC3 may be used for the colors of fabric. Furthermore, as shown in FIG. 7E, a company logo may be written in the universal color UC1. This can reduce the difference in color recognition between people with color-blindness and people with normal color vision.

[0045] [Variations] The present disclosure has been described in detail above based on the embodiments. However, the present disclosure is not limited to the above embodiments. The present disclosure can be modified in various ways without departing from the spirit and scope of the present disclosure.

[0046] In the tags shown in FIG. 2C and FIG. 2E, the first color E1 and the second color F1 are displayed together with a plurality of colors, but it is also possible to display only a plurality of colors.

[0047] 5 has been described as an example in which six types of tags are prepared for one color, but the number of types of tags for one color is not particularly limited, and for example, there may be only one type of tag for one color. When there is only one type of tag for one color, the tag table TB1 shown in FIG. 5 may be composed of only columns for "item color" and "tag identifier."

[0048] The first region R1 and the second region R2 may indirectly indicate the color by using a QR code (registered trademark) or the like.

[0049] When the universal color is not adopted, the color conversion device 200 does not need to acquire and use the consideration ratio. When the P-type cone sensitivity function and the D-type cone sensitivity function are stored in the memory 202, the color conversion device 200 only needs to receive information about the color-blind person and determine the cone sensitivity function to be used.

[0050] The articles according to the present disclosure are classified into various categories. The categories include, for example, food, clothing, and shelter, clothing / fashion, school / children, brand / advertising, toys, and others. Specific examples of articles included in these categories are as follows. Articles related to food, clothing, and shelter include, for example, clothing, food containing coloring agents, tableware, tablecloths, wallpaper, furniture, bedding, and the like. Articles related to food, clothing, and shelter may be combinations of wallpaper, furniture, bedding, and the like with lighting. Examples of clothing / fashion-related items include umbrellas, hats, hairpins, hair ties, headbands, hair bands, glasses, sunglasses, earrings, pierced earrings, earphones, cosmetics, nail art items (nail polish, gel, stickers, etc.), necklaces, ties, scarves, mufflers, shawls, tie pins, inner tops, outer tops, inner bottoms, outer bottoms, gloves, wristbands, bracelets, watches, smart watches, rings, smartphone cases, bags, belts, socks, leggings, tights, stockings, anklets, shoes, sandals, geta (wooden clogs), slippers, folding fans, handkerchiefs, towels, etc. Examples of school / children-related items include stationery, notebooks, letter sets, tool cases, school bags, textbooks / teaching materials, uniforms, gym clothes, indoor shoes, paint sets, lunch boxes, crayons, sticky notes, files, binders, etc. Examples of brand / advertising related items include items with logos, signs, advertising items, packaging (drinks, sweets, book covers, CD jackets), etc. Examples of toy related items include stuffed toys / dolls, play house supplies, clay, etc. Other items include candles, soap, business cards, etc. Thus, the items according to the present disclosure are diverse, with specific items included in each category.

[0052] According to the tag of Appendix 1, the color of an object as perceived by a person with general color vision is displayed in a manner perceivable by a person with color weakness. Therefore, this tag allows a person with color weakness to recognize how an object looks to a person with general color vision. A person with color weakness will not make a mistake in selecting the color of an object, and color weakness can give the person with color weakness confidence in selecting a color. Alternatively, according to this tag, the color of an object as perceived by a person with color weakness is displayed in a manner perceivable by a person with general color vision. Therefore, this tag allows a person with general color vision to recognize how an object looks to a person with color weakness. Therefore, this tag can display the color of an object taking color vision diversity into consideration.

[0053] According to Appendix 2, the tag allows a person with color-blindness to perceive the color of an item in the same way that a person with normal color vision sees it.
