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

[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 perceptible to a person with color blindness. The second region indicates the color of the article as perceived by a person with color blindness in a manner perceptible to 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 perceptible to 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 perceptible to 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 indicates the color of the article as perceived by a person with normal color vision in a manner perceptible to a person with color deficiency, and a second region that indicates the color of the article as perceived by a person with color deficiency in a manner perceptible to 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, the article with the tag 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 color vision variability into account.

[0009] According to various aspects of the present disclosure, the color of an article can be displayed taking color vision variability into account.

[0010] FIG. 1 is a diagram showing an example of clothing equipped with a tag according to an embodiment. FIGS. 2A to 2E are each a diagram showing an example of a tag according to an embodiment. FIG. 3 is a flowchart showing an example of a method for providing an item. FIG. 4 is a diagram showing an example of the configuration of a tag determination device. FIG. 5 is a diagram showing an example of a tag table. FIG. 6 is a diagram showing an example of the configuration of a color conversion device. FIGS. 7A to 7E are each a diagram showing an example of how colors are represented in various embodiments.

[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 redundant description will be omitted.

[0012] [Overview of Color Vision Variation] The concept of the present disclosure is to provide a technology for displaying colors taking color vision variability into consideration. Color vision variability refers to situations in which people differ in their perception or discrimination of colors. People with different color vision have difficulty reaching a common understanding 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] Meanwhile, people with P, D, T, and A types are also called colorblind. P type is a group consisting of P type strong (Protanopia) who do not have L cones and P type weak (Protanomaly) in which 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) in which 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 account for the majority of colorblind people, with T type and A type accounting for an extremely small proportion.

[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 perception is perceived by a person with normal color vision, or vice versa. The tags may be designed to promote common perception or mutual understanding of colors among people with C, P, and D color vision. The present disclosure also provides examples of using colors on articles that are perceived the same by both people with normal color vision and people with color blindness.

[0017] [Overview of Tags] Tags are attached to items and indicate information about the color of the item. Items include, for example, clothing, fabric, furniture, accessories, etc., and are not particularly limited as long as they are colored objects. Clothing refers to all things worn, including clothes, underwear, hats, scarves, gloves, footwear, etc. The following describes an example in which the item is clothing. "Attaching a tag" does not only mean that the tag is sewn directly onto the item, but also that the tag is attached to the item with a string like a price tag. Alternatively, "attaching a tag" may mean that the tag and the item are indirectly, i.e., logically, linked.

[0018] FIG. 1 is a diagram showing an example of clothing equipped with a tag according to an embodiment. As shown in FIG. 1, a tag 1 is attached to clothing 10. In the example shown in FIG. 1, the tag 1 is sewn to the lining of the clothing 10. Another tag 11 may be sewn to the clothing 10. The clothing 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] 2A to 2E are diagrams illustrating an example of a tag according to an embodiment. The tag 1 shown in FIG. 2A has a first region R1 and a second region R2. The first region R1 is an area for displaying information for color-blind individuals. The first region R1 includes information for color-blind individuals showing how a color C1 appears to a person with general color vision. As a more specific example, the first region R1 displays a graphic 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 individual viewing the first region R1 matches the response of the color vision system of a person with general color vision viewing the clothing 10. "The responses of both match" does not only mean that the difference between the responses is zero, but also means that it is below a predetermined threshold. In other words, the match includes a predetermined range of similarity, and the threshold can be determined through testing. The first region R1 allows color-blind individuals 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. that indicate the first color E1 without including the first color E1. For example, the first region R1 may include only characters such as "red" or "blue," or may include only symbols such as "R" or "G."

[0020] The second region R2 is an area 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 color-blind person. As a more specific example, the second region R2 displays a graphic of clothing having a second color F1. The second color F1 has a spectrum configured so that the response of the color vision system of a person with general color vision who views the second region R2 matches the response of the color vision system of a person with color-blindness who views the clothing 10. "The responses of both match" does not only mean that the difference between the responses is zero, but also means that it is below a predetermined threshold. In other words, the match includes a predetermined range of similarity, and the threshold can be determined through testing. The second region R2 allows people with general color vision to recognize how the clothing 10 appears to a person with color-blindness. The second region R2 may additionally include characters, symbols, etc. indicating the second color F1. The second region R2 may also 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 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 only has 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 multiple colors E11 and E12 that can be perceived by color-blind people. The multiple colors E11 and E12 are colors that, when mixed, become the first color E1 perceived by people with general color vision. For example, if 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 for the combination can be simplified (reduced to primary colors). Therefore, the tag 1B can display the first color E1 perceived by people with general color vision in a manner that is easy for color-blind people 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 general 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 general color vision. The predetermined range can be determined through testing. Hereinafter, in this disclosure, a color that can be perceived as approximately the same by both color-blind people and people with general color vision is referred to as a universal color. By using universal colors, tag 1B can make the information for color-blind people written on tag 1B understandable to people with general color vision.

[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 general 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 multiple colors F11 and F12 that are perceptible to people with general color vision. The multiple colors F11 and F12 are colors that, when mixed, become the second color F1 perceived by people with color blindness. For example, if 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 base of the combination are simplified (reduced to primary colors). Therefore, the tag 1D can display the second color F1 perceived by people with color blindness in a manner that is easy for people with general color vision to recognize.

[0024] Each of the plurality of colors F11, F12 may be a color in which the difference in response between the color vision system of a color-blind person and 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 make the information written on the tag 1D intended for people with normal color vision understandable to people with color-blindness.

[0025] The multiple colors E11 and E12 described using Fig. 2C and the multiple colors F11 and 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 first region R1 and second region R2, a tag (not shown) that provides a display of multiple color combinations in tag 1, tag 1A having only first region R1, tag 1B that provides a display of multiple color combinations in tag 1A, tag 1C having only second region R2, and tag 1D that provides a display of multiple color combinations 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] [Outline of the method for providing an item] 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 a tag (step S12), and a step of providing the item (step S14).

[0028] In the step of determining a tag (step S10), a device or a person determines a tag to be attached to an item based on the color of the item. First, a case where a device determines a 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 configured by one computer or multiple computers connected to each other via a communication network. A computer generally includes hardware devices such as a processor, memory, a communication interface, an input device, and an output device. Examples of the processor include a CPU and a GPU. The memory includes a flash memory, a hard disk, etc. 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, for 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 which 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 "item color" with "tag identifier." The "tag identifier" is further associated with "information presentation target," "multiple-color display," "color of first region," and "color of second region."

[0031] In the example shown in Figure 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. "multiple color display" is information that indicates whether or not a mode is used to display multiple colors in combination. "first region color" is the color displayed in the first region R1. "second region color" is the color displayed in the second region R2.

[0032] Next, the operation of the tag determination device 100 will be described. First, the processor 101 receives color information of the clothing 10. The processor 101 may receive color information input by a user of the tag determination device 100, or may receive 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 received color information. The processor 101 outputs the determined tag as tag determination information.

[0033] For example, when the processor 101 receives the color "C1" of an item, the processor 101 refers to the tag table TB1 and acquires tag identifiers "T1" to "T6" associated with the color "C1" of the item. 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 the "information presentation target" and the "multiple color display" and selects one tag identifier based on the user's response. For example, if the user responds that the information presentation target is "for color-blind people" and that the multi-color display is "off," 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 completes the tag determination step (step S10) shown in FIG. 3. When the tag determination step (step S10) is performed by a person, the person may select a tag according to the color of the item by referring to the tag table TB1 shown in FIG. 5, for example.

[0035] When the step of determining the tag is completed, a step of attaching a tag (step S12) is executed. In the tag attaching step, 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, giving away, selling, etc.

[0036] This completes the process 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] [Colors Displayed on Tag] The colors displayed in the first region R1 and the second region R2 are determined based on the color of the item. The following provides an overview of the configuration and operation of a device that determines the colors displayed in the first region R1 and the second region R2. Hereinafter, the color of the item is referred to as the base color, the color of the first region R1 is referred to as the first color, and the color of the second region R2 is referred to as the second color. The first color is a color having a spectrum configured so that the response of the color vision system of a color-blind person viewing 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 so that the response of the color vision system of a person with general color vision who perceives the second region R2 matches the response of the color vision system of a person with color-blindness 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 a single computer or multiple 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 pre-stores the cone sensitivity functions of a person with normal color vision and a person with color-blindness. The cone sensitivity functions, also known as color vision systems, are the sensitivity characteristics of L cones, M cones, and S cones, and indicate the relationship between wavelength and relative sensitivity. The cone sensitivity functions output a response depending on the shape of the input spectrum. Cone sensitivity functions may be prepared for each type of color vision; 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 visible light region of the base color. Then, based on the spectrum of the visible light region of the base color and the cone sensitivity function of a person with general color vision stored in memory 202, the processor 201 obtains the responses (three numbers) of the L cones, the M cones, and the S cones. Next, based on the spectrum of the visible light region of the base color and the cone sensitivity function of a person with color weakness stored in memory 202, the processor 201 obtains the responses (three numbers) of the L cones, the M cones, and the S cones. The processor 201 then repeatedly changes the shape of the spectrum of the base color and obtains the corresponding responses of a person with color weakness so that the responses of the person with color weakness approach (match) the responses of a person with general color vision. This results in a spectrum in which the responses of the person with color weakness match the responses of a person with general color vision. 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 way 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 a person with normal color vision so that the response of a person with normal color vision approaches (matches) the response of a person with color blindness. This results in a spectrum in which the response of a person with normal color vision matches the response of a person with color blindness. The color of the spectrum obtained in this way is the second color described above.

[0041] Next, universal colors, which are multiple colors displayed in the first region R1 and the second region R2, will be described. Universal colors can be generated based on two colors and a consideration ratio. The consideration ratio is the degree of consideration for color vision diversity and is a numerical value ranging from 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 the 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 matches the response of the color vision system of a person with normal color vision perceiving the base color, and is the first color described above. The processor 201 inputs the consideration ratio and linearly combines the spectrum of the base color (or a color obtained by varying the spectrum of the base color) and the spectrum of the first color according to the consideration ratio to achieve the input consideration ratio, and outputs a spectrum that has been changed to correspond to the consideration ratio. As an example, universal colors can be generated with a consideration ratio of 20% or close to that value. The processor 201 may also output a spectrum that has been changed to correspond to the consideration ratio in different ways. For example, the processor 201 prepares a color whose spectrum shape is changed so that the response of a color-blind person approaches (matches) the response of a person with general color vision under the condition that the RGB of the base color is constant. When creating a color whose consideration rate is higher than the prepared color, the processor 201 linearly combines the prepared color and a color whose consideration rate is 100% according to the consideration rate, and outputs a spectrum changed to correspond to the consideration rate.

[0042] Various embodiments of a technology for displaying colors taking color vision diversity into consideration will be described. FIGS. 7A to 7E are diagrams showing examples of how colors are displayed in various embodiments. The tag 1 shown in FIG. 2A and other figures is not limited to clothing 10, but can also be attached to furniture such as a sofa, as shown in FIG. 7A. 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 general color vision, even regarding the colors of furniture or small items.

[0043] The first color described in the present disclosure may be applied to clothing without using a tag. For example, as shown in FIG. 7B, the lining of a garment of color C1 may be the first color E1. This allows the colors of the front and back of a reversible garment to be related, thereby enhancing mutual understanding between people with color blindness and those with normal color vision.

[0044] The universal colors disclosed in this disclosure can be applied to a variety of items. For example, as shown in Figure 7(C), universal color UC1 may be used for clothing colors. Alternatively, as shown in Figure 7(D), universal colors UC1, UC2, and UC3 may be used for fabric colors. Furthermore, as shown in Figure 7(E), corporate logos and the like may be displayed in universal color UC1. This can reduce the difference in color perception between people with color blindness and those with normal color vision.

[0045] [Modifications] 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 FIGS. 2C and 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 illustrates 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. In this case, the tag table TB1 shown in FIG. 5 may be composed of only the columns "item color" and "tag identifier."

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

[0049] If universal colors are not adopted, the color conversion device 200 does not need to acquire and use the consideration ratio. If P-type cone sensitivity functions and D-type cone sensitivity functions are stored in the memory 202, the color conversion device 200 can simply accept information about color-blind individuals and determine the cone sensitivity function to use.

[0050] [Supplementary Notes] As can be seen from the various examples above, the present disclosure includes the following aspects.

[0051] According to the tag of Supplementary Note 1, the color of an item perceived by a person with general color vision is displayed in a manner that is perceptible to a person with color weakness. Therefore, this tag allows a person with color weakness to recognize how an item looks to a person with general color vision. This prevents a person with color weakness from making a mistake in selecting the color of an item, and allows the person with color weakness to gain confidence in their color selection. Alternatively, according to this tag, the color of an item perceived by a person with color weakness is displayed in a manner that is perceptible to a person with general color vision. Therefore, this tag allows a person with general color vision to recognize how an item looks to a person with color weakness. Therefore, this tag can display the color of an item taking color vision diversity into consideration.

[0052] According to Supplementary Note 2, the tag allows a person with color-blindness to perceive the color of an item in the same way as a person with normal color vision.

[0053] According to Supplementary Note 3, the tag allows a person with normal color vision to perceive the appearance of an item to a color-blind person in terms of color.

[0054] According to Appendix 4, the tag can indicate the color of the item as perceived by people with normal color vision in a manner that is easily recognizable to people with color blindness.

[0055] According to Appendix 5, by adopting colors that have little difference in recognition between color-blind people and people with normal color vision, the tags can make the information written on the tags for color-blind people understandable to people with normal color vision.
