Description

Technical Field

[0001] The present invention relates to a color-coded keyboard for communication and a method for transmitting selected characters of the keyboard, etc.

Background Art

[0002] Patent Document 1 below discloses an invention whose problem to be solved is to provide a means of communicating intention and a method of communicating intention that can utilize the keyboard normally used by disabled and / or elderly people. Specifically, conventional means of communicating intention require a dedicated keyboard. Since it is assumed that the types and / or arrangements of characters and / or symbols are different between such a dedicated keyboard and the keyboard normally used by disabled people, etc., disabled people, etc. must perform an operation of inputting characters according to the configuration of the dedicated keyboard of the device (a keyboard not normally used), rather than the operation of inputting characters they are used to. As a result, it is described that they feel a great deal of stress.

[0003] And in order to reduce such stress, etc., according to the invention of Patent Document 1, there are provided a means for setting a region of transmitted information corresponding to the transmitted information of the keyboard from an image of a keyboard having a plurality of transmitted information, an input means for inputting position information on the keyboard, a discriminating means for discriminating the region of transmitted information corresponding to the position information, and a specifying means for specifying the region on the keyboard corresponding to the discriminated region of transmitted information. It is described that a means of communicating intention having these is proposed.

[0004] However, even when using a familiar letter board, mutual proficiency and skill are still necessary between the user and the caregiver. Accurately identifying and confirming selected letters based on eye movement and reading what the gaze is fixed on is a high hurdle for inexperienced beginners. Furthermore, even with transparent letter boards used by ALS patients, it is necessary to move the transparent letter board to read what the gaze is directed at, and in many cases, it is necessary to move from one corner of the letter board to the opposite corner (i.e., a long-distance movement along the entire diagonal of the letter board) in order to select and read the next letter.

[0005] Furthermore, when using a finger-based letter board, for example, if the user wants to select "wa," they must wait until the sequential sorting process, which starts from the "a" row (this sorting is often done by the caregiver calling out names or by pointing to the letter board), reaches the "wa" row. Only when the user finally reaches the "wa" row can they indicate their intention to select that letter to the caregiver through blinking or other means. As a result, indicating the choice of letter takes an extremely long time and places a considerable amount of effort on the caregiver. [Prior art documents] [Patent Documents]

[Figure 3] It is a diagram for explaining variations of the color-coded character board for communication according to the present invention. [Figure 4]This diagram illustrates variations of the color-coded communication dial according to the present invention. [Figure 5] This is a diagram illustrating a color-coded communication dial according to the third embodiment. [Figure 6] This is a diagram illustrating a color-coded communication dial according to the fourth embodiment. [Figure 7] This figure corresponds to Figure 1, which does not include the reference numerals. [Figure 8] This figure corresponds to Figure 2, which does not include the reference numerals. [Figure 9] This figure corresponds to Figure 5, which does not have the reference numerals indicated. [Figure 10] This figure corresponds to Figure 6, which does not include the reference numerals. [Figure 11] This diagram illustrates an example of a communication board configuration that uses no background color (i.e., no background color), and is divided into four colors each by the color of the border around the communication symbols and the color of the communication symbols themselves. (a) shows an example where color selection bars (color bands) are placed above and below the symbol placement area, and (b) illustrates an example without color selection bars (color bands). [Figure 12] This diagram illustrates an example of a communication board configuration where the background color of the communication symbols and the color of the communication symbols themselves are used to create four different colors, without using the border color of the communication symbols (i.e., no border color). (a) shows an example where the color selection bar is placed at the top of the symbol placement area, and (b) shows an example where the color selection bar is placed at the bottom of the symbol placement area. [Figure 13] The color of the communication symbols themselves is constant (typically black), and the symbols are grouped by color based on the color of the border around the symbol (vertically arranged with the same border color) and the background color (horizontally arranged with the same background). (a) shows an example where color selection bars (color bands) are placed above and below the symbol placement area, and (b) illustrates an example without color selection bars (color bands). [Figure 14]The color of the communication symbols themselves is constant (typically black), and the symbols are grouped by color based on the color of the border around the communication symbol (horizontally arranged with the same border color) and the background color (vertically arranged with the same background). (a) shows an example where a color selection bar (color band) is placed above the symbol placement area, and (b) illustrates an example where a color selection bar (color band) is placed above the symbol placement area. [Figure 15] This diagram illustrates an example of using two-color coding, with a frame color and a background color (the symbol color is constant (e.g., black)), for custom display only (custom symbols are arbitrary). (a) illustrates an example where the frame color is the same color and arranged vertically, and the background color is the same color and arranged horizontally, with color selection bars at the top and bottom. (b) illustrates an example where the frame color is the same color and arranged horizontally, and the background color is the same color and arranged vertically, with color selection bars on the left and right. [Figure 16] This diagram illustrates an example of using three color codings for the frame color and symbol color (no background color) to create a custom display only (custom symbols are optional). (a) illustrates an example where the frame color is the same color and arranged vertically, and the symbol color is the same color and arranged horizontally, with color selection bars at the top and bottom. (b) illustrates an example where the frame color is the same color and arranged horizontally, and the symbol color is the same color and arranged vertically, with a color selection bar only at the bottom. [Figure 17] This diagram illustrates an example of using five color codings for background and symbol colors (without border colors) to create a custom display only (custom symbols are optional). (a) illustrates an example where the background color is the same color and arranged vertically, the symbol color is the same color and arranged horizontally, with a color selection bar at the top. (b) illustrates an example where the background color is the same color and arranged horizontally, the symbol color is the same color and arranged vertically, without a color selection bar. [Modes for carrying out the invention]

[0024] This invention provides a character board that allows users requiring assistance to select characters and other elements more easily. Because selection is done by color, there are fewer errors in predicting where the user's gaze is directed, and it is possible to communicate the selected item to the caregiver smoothly and easily through eye movements. Furthermore, because the target area for the user's gaze is larger compared to characters (allowing for a larger area of ​​the selection color region), it is easier for the user to move their eyes, and it is also extremely easy for the caregiver to predict and read where the user is looking, resulting in fewer errors and a shorter reading time.

[0025] Similar effects and benefits can be obtained when using such a communication letter board for specific selections by pointing, or when selecting colors using spoken word descriptions. Furthermore, it is possible to arrange the color scheme and other elements to be optimal according to the individual condition and characteristics of each person requiring care.

[0026] Traditionally, eye-tracking by caregivers has not been something that anyone can easily do right away. It requires long periods of practice, skill, and the acquisition of techniques, as well as mutual understanding of habits, characteristics, and personalities between the caregiver and the person receiving care, and a relationship of trust. However, this invention reduces such high hurdles.

[0027] (First embodiment) Figure 1 illustrates a color-coded communication dial 1000 according to the first embodiment. Figure 1(a) illustrates the case in which color bands 1100(1) and 1100(2) are provided as color selection areas in the space above and below the character group display area 1200, Figure 1(b) illustrates the case in which color bands 1100(1) and 1100(2) are not provided, Figure 1(c) illustrates the case in which a color band 1100 is provided as a color selection area in the space above the character group display area 1200, and Figure 1(d) illustrates the case in which a color band 1100 is provided as a color selection area in the space below the character group display area 1200.

[0028] As shown in Figure 1, the color-coded communication dial 1000 is used to communicate intentions to a caregiver by sequentially selecting, for example, one character at a time to form sentences or words. The character group display area 1200 shows an alphabet, symbols, numbers, and multiple custom words, but it can also be Hiragana, French, German, Russian, Chinese, Arabic, Hangul, etc., and the characters displayed can be any characters related to communication.

[0029] In Figure 1(a), the character group display area 1200 is classified into six background colors from left to right on the page: red background 1210, blue background 1220, green background 1230, yellow background 1240, light blue background 1250, and purple background 1260. As shown in Figure 1(a), for example, the red background 1210 contains the six characters "Q", "W", "A", "S", "Z", and "X", the blue background 1220 contains the six characters "E", "R", "D", "F", "C", and "V", and similarly, the other background colors 1230 to 1260 each contain any six characters.

[0030] Furthermore, as shown in Figure 1(a), each character on the color-coded communication character board 1000 is displayed in a color-coded font. For example, "Q" is displayed in red font 1310, "W" in blue font 1320, "A" in green font 1330, "S" in yellow font 1340, "Z" in light blue font 1350, and "X" in purple font 1360. That is, for example, if a person requiring care wants to select the character "A", they would first select the red band 1110 with their gaze or by pointing to convey the red background 1210, and then select the green band 1130 with their gaze or by pointing to convey the green font 1330.

[0031] Similarly, for example, "E" is displayed in red font 1310, "R" in blue font 1320, "D" in green font 1330, "F" in yellow font 1340, "C" in light blue font 1350, and "V" in purple font 1360. That is, for example, if a person requiring care wants to select the letter "D", they would first select the blue band 1120 with their eyes or by pointing to convey the blue background 1220, and then select the green band 1130 with their eyes or by pointing to convey the green font 1330. Also, 1140 is a yellow band, 1150 is a light blue band, and 1160 is a purple band. These color schemes, orders, and arrangements can be arbitrary.

[0032] Furthermore, since the area occupied by each of these color bands 1110 to 1160 is preferably larger than the area occupied by each individual character shown in the character group display area 1200, the movement and fixing of the gaze and pointing fingers are easy and quick, and it is also easy for caregivers to read, recognize, and grasp them, reducing the time and effort required for errors and confirmations, and enabling accurate and rapid communication.

[0033] As mentioned above, while it is acceptable for the same font color to be used multiple times between characters with different background colors, font colors should not be used multiple times between characters with the same background color. If there is duplication, it becomes unclear which character is intended to be communicated when that color is indicated, resulting in the need for additional confirmation and selection. It is preferable that there are no duplicate colors in the color selection at each stage, from background color selection (broad concept) to font color selection (detailed concept). However, even with duplicate colors, it is possible to create a character design that is easily distinguishable by differentiating them with varying shades.

[0034] In Figures 1(b), 1(c), and 1(d), the color scheme and arrangement of the font color and background color of the characters shown in the character group display area 1200 are the same as in the embodiment shown in Figure 1(a), and only the presence or absence and position of the color band 1100 differ, so no explanation is necessary. In the embodiment of Figure 1(b), the color band 1100 is not shown, but it is possible to provide the color band 1100 separately on a separate transparent substrate sheet, for example, separate from the color-coded character panel 1000 for communication, and this achieves certain effects of the present invention in that it is possible to specify and transmit each character solely by selecting and transmitting colors.

[0035] (Second Embodiment) Figure 2 illustrates a color-coded communication dial 2000 according to a second embodiment. Figure 2(a) illustrates the case in which color bands 1100(1) and 1100(2) are provided as color selection areas in the space above and below the character group display area 2200, Figure 2(b) illustrates the case in which color bands 1100(1) and 1100(2) are not provided, Figure 2(c) illustrates the case in which a color band 1100 is provided as a color selection area in the space above the character group display area 2200, and Figure 2(d) illustrates the case in which a color band 1100 is provided as a color selection area in the space below the character group display area 2200.

[0036] As shown in Figure 2, the color-coded communication dial 2000 is, for example, made of a transparent resin sheet substrate on which alphabets and arbitrary custom characters, symbols, and numbers are displayed. Multiple characters of each type are neatly arranged in approximately the same area, and it is used to communicate intentions to a caregiver by sequentially selecting, for example, one character at a time to form sentences or words. In Figure 2, the character group display area 2200 is shown to display alphabets, symbols, numbers, and multiple custom words, but it may also display hiragana, French, German, Russian, Chinese, Arabic, Hangul, etc., and the characters displayed may be any characters related to communication.

[0037] In Figure 2(a), the character group display area 2200 is divided into six character frame colors, from left to right: red frame 1410, blue frame 1420, green frame 1430, yellow frame 1440, light blue frame 1450, and purple frame 1460. For the sake of explanation, each color frame 1410 to 1460 is shown enclosed by a dashed line, but as shown in Figure 2, each character type located within each dashed line has its own separate rectangular color frame. As shown in Figure 2(a), for example, the alphabet characters individually enclosed in the red frame 1410 include the six characters "Q", "W", "A", "S", "Z", and "X", and for example, the blue frame 1420 includes the six characters "E", "R", "D", "F", "C", and "V", and similarly, any six characters can be included in each of the other color frames 1430 to 1460.

[0038] Furthermore, as shown in Figure 2(a), each character on the color-coded communication character board 2000 is displayed using a color-coded font. For example, "Q" is displayed in red font 1310, "W" in blue font 1320, "A" in green font 1330, "S" in yellow font 1340, "Z" in light blue font 1350, and "X" in purple font 1360. That is, for example, if a person requiring care wants to select the character "A", they would first select the red band 1110 with their gaze or by pointing to convey the red frame 1410, and then select the green band 1130 with their gaze or by pointing to convey the green font 1330.

[0039] Similarly, for example, "E" is displayed in red font 1310, "R" in blue font 1320, "D" in green font 1330, "F" in yellow font 1340, "C" in light blue font 1350, and "V" in purple font 1360. That is, for example, if a person requiring care wants to select the letter "D", they would first select the blue band 1120 with their eyes or by pointing to convey the blue frame 1420, and then select the green band 1130 with their eyes or by pointing to convey the green font 1330. Also, 1140 is a yellow band, 1150 is a light blue band, and 1160 is a purple band. These color schemes, orders, and arrangements can be arbitrary.

[0040] Furthermore, since the area occupied by each of these color bands 1110 to 1160 is preferably larger than the area occupied by each individual character shown in the character group display area 2200, the movement and fixing of the gaze and pointing fingers are easy and quick, and it is also easy for caregivers to read, recognize, and grasp them, reducing the time and effort required for errors and confirmations, and enabling accurate and rapid communication.

[0041] As mentioned above, while it is acceptable for the same font color to be used multiple times between characters with different border colors, font colors should not be used multiple times between characters within the same border color. If this were to happen, it would become unclear which character the user intended to communicate when they specified a particular color, resulting in the need for additional confirmation and selection. It is preferable that there are no duplicate colors in the color selection process at each stage, from background color selection (broad concept) to font color selection (detailed concept).

[0042] In Figures 2(b), 2(c), and 2(d), the color scheme and arrangement of the font color and background color of the characters shown in the character group display area 2200 are the same as in the embodiment shown in Figure 2(a), and only the presence or absence and position of the color band 1100 differ, so no explanation is necessary. In the embodiment of Figure 2(b), the color band 1100 is not shown, but it is possible to provide the color band 1100 separately on a separate transparent substrate sheet, for example, separate from the color-coded character panel 2000 for communication, and this achieves certain effects of the present invention in that it is possible to specify and transmit each character solely by selecting and transmitting colors.

[0043] Figures 3 and 4 illustrate variations of the color-coded communication dial according to the present invention. In all cases, it is possible to reach and communicate a single character or character section (custom, etc.) by simply repeating the color specification process in several stages. Color selection is intuitive and relatively easy. Furthermore, a relatively large area can be allocated for color specification, enabling quick and easy selection.

[0044] Furthermore, as shown in Figures 3 and 4, the placement, arrangement, size, and occupied area of ​​each font character are arbitrary, and the background color, character color (font color), frame color, and the size and range of the frame (size and number of groups of characters to which that color belongs) can also be arbitrary. In addition, transparent film / plates, white film / plates, and other known arbitrary materials and colors can be used as the base material for the color-coded character board for communication, and the size can be any size suitable for the user, such as A4 or A5. Moreover, one or more of the three elements—background color, character color (font color), and frame border color (color coding per character, color coding per row, color coding per column, color coding per group, etc.)—can be appropriately combined or used to configure the system so that a single character can be selected with multiple color specifications. For example, a system can be configured so that a single character can be selected with three color selections using a group-based color-coded frame border color, a column-based (or row-based) color-coded frame border color, and a character-based color-coded frame border color.

[0045] (Third embodiment) Figure 5 illustrates a color-coded communication dial 3000 according to a third embodiment. Figure 5(a) illustrates the case where color bands 1100(1) and 1100(2) are provided as color selection areas in the space above and below the character group display area 3200, Figure 5(b) illustrates the case where color bands 1100(1) and 1100(2) are not provided, Figure 5(c) illustrates the case where a color band 1100 is provided as a color selection area in the space above the character group display area 3200, and Figure 5(d) illustrates the case where a color band 1100 is provided as a color selection area in the space below the character group display area 3200.

[0046] As shown in Figure 5, the color-coded communication dial 3000 is, for example, a transparent resin sheet base plate on which hiragana and arbitrary custom characters, symbols, numbers, and punctuation marks are displayed. Multiple characters of each type are neatly arranged in approximately the same area, and it is used to communicate the intentions of the person being cared for to a caregiver by sequentially selecting, for example, one character at a time to form sentences or words. In Figure 5, the character group display area 3200 is shown with hiragana, symbols, numbers, and multiple custom words displayed, but it may also be the alphabet, French, German, Russian, Chinese, Arabic, Hangul characters, etc., and the displayed characters may be all or some of any characters related to the user's communication.

[0047] In Figure 5(a), the hiragana characters in the character display area 3200 are grouped and arranged within two colored frames, red 1510 and blue 1520, from right to left on the page. As shown in Figure 5(a), for example, the characters enclosed in red 1510 include the hiragana characters from the "a-row," "ka-row," "sa-row," "ta-row," and "na-row," as well as the numbers 6, 7, 8, 9, and 0. Similarly, blue 1520 includes the hiragana characters from the "ha-row," "ma-row," "ya-row," "ra-row," and "wa-row," as well as the numbers 1, 2, 3, 4, and 5, and punctuation marks.

[0048] In Figure 5(a), within the red frame 1510 and the blue frame 1520 of the character group display area 3200, the background colors are classified into five vertical columns from left to right: light blue background 1250, yellow background 1240, green background 1230, blue background 1220, and red background 1210. As shown in Figure 5(a), for example, the red background 1210 of the red frame 1510 contains the six characters "あ", "い", "う", "え", "お", and "0", and for example, the blue background 1220 of the red frame 1510 contains the six characters "か", "き", "く", "け", "こ", and "9", and similarly, each of the other background colors contains any six characters or punctuation marks.

[0049] More specifically, the "a row" and "ha row" shown in FIG. 5 are set to a red background 1210, the "ka row" and "ma row" are set to a blue background 1220, the "sa row" and "ya row" are set to a green background 1230, the "ta row" and "ra row" are set to a yellow background 1240, and the "na row" and "wa row" are set to a light blue background 1250.

[0050] Furthermore, as shown in FIG. 5(a), each character type of the communication color-coded character board 3000 is color-coded and displayed using a color-coded font. For example, "a" is displayed using a red font 1310, "i" is displayed using a blue font 1320, "u" is displayed using a green font 1330, "e" is displayed using a yellow font 1340, "o" is displayed using a light blue font 1350, and "0" is displayed using a purple font 1360. The same applies to the font colors of other columns, such as the "ka row" and "sa row"..., the "ha row" and "ma row".... That is, for example, when a caregiver wants to select and convey the character "a", first, the red band 1110 is selected by line of sight or pointing with a finger or the like to convey the red large frame 1510, then the red band 1110 is selected by line of sight or pointing with a finger or the like to convey the red background 1210, and then the red band 1110 is selected by line of sight or pointing with a finger or the like to convey the red font 1310.

[0051] Similarly, for example, "wa" is displayed using a red font 1310, "wo" is displayed using a blue font 1320, "n" is displayed using a green font 1330, "、" is displayed using a yellow font 1340, "。" is displayed using a light blue font 1350, and "1" is displayed using a purple font 1360. That is, for example, when a caregiver wants to select and convey the character "n", first, the blue band 1120 is selected by line of sight or pointing with a finger or the like to convey the blue large frame 1520, and then the green band 1130 is selected by line of sight or pointing with a finger or the like to convey the green font 1330. Also, 1140 is a yellow band, 1150 is a light blue band, and 1160 is a purple band. These color arrangements, orders, and arrays can be arbitrary ones suitable for the user.

[0052] Furthermore, since the area occupied by each of these color bands 1110 to 1160 is preferably larger than the area occupied by each individual character shown in the character group display area 3200, the movement and fixation of the gaze and pointing fingers are easy and quick, and it is also easy for caregivers to read, recognize, and grasp (or guess) them, reducing the time and effort required for errors and confirmations, and enabling accurate and rapid communication.

[0053] As mentioned above, while it is acceptable for the same font color to be used multiple times between characters with different border colors, font colors should not be used multiple times between characters within the same border color. If this were to happen, it would become unclear which character the user intended to communicate when they specified a particular color, resulting in the need for additional confirmation and selection. It is preferable that there are no duplicate colors in the color selection process at each stage, from background color selection (broad concept) to font color selection (detailed concept).

[0054] In Figures 5(b), 5(c), and 5(d), the color scheme, arrangement, and overall color framework of the font and background colors of the characters shown in the character group display area 3200 are the same as in the embodiment shown in Figure 5(a), with only the presence or absence and position of the color band 1100 being different, so no explanation is necessary. In the embodiment of Figure 5(b), the color band 1100 is not shown, but it is possible to provide the color band 1100 separately on a separate transparent substrate sheet, for example, separate from the color-coded character panel 3000 for communication, and this achieves certain effects of the present invention in that it is possible to specify and transmit each character solely by selecting and transmitting colors.

[0055] In the example shown in Figure 5, a single character can be identified through three stages of color specification: a major conceptual color specification stage that specifies the color of the second group of borders, a medium conceptual color specification stage that specifies the background color, and a minor conceptual color specification stage that specifies the font color. In each color specification stage, the desired color can be selected from the color bands arranged in the color selection area.

[0056] (Fourth embodiment) Figure 6 illustrates a color-coded communication dial 4000 according to the fourth embodiment. The fourth embodiment differs from the third embodiment in that it uses character frames 1450, 1440, 1430, 1460, and 1410 instead of font background colors 1250, 1240, 1230, 1260, and 1210.

[0057] Figure 6(a) illustrates the case where the character group display area 4200 has color bands 1100(1) and 1100(2) as color selection areas in the space above and below it, respectively; Figure 6(b) illustrates the case where the character group display area 4200 does not have color bands 1100(1) and 1100(2); Figure 6(c) illustrates the case where the character group display area 4200 has a color band 1100 as a color selection area in the space above it; and Figure 6(d) illustrates the case where the character group display area 4200 has a color band 1100 as a color selection area in the space below it.

[0058] As shown in Figure 6, the color-coded communication dial 4000 is, for example, a transparent resin sheet base plate on which hiragana and arbitrary custom characters, symbols, numbers, and punctuation marks are displayed. Multiple characters of each type are neatly arranged in approximately the same area, and it is used to communicate the intentions of the person being cared for to a caregiver by sequentially selecting, for example, one character at a time to form sentences or words. In Figure 6, the character group display area 4200 is shown to display hiragana, symbols, numbers, and multiple custom words, but it may also display the alphabet, French, German, Russian, Chinese, Arabic, Hangul characters, etc., and the displayed characters may be all or some of any characters related to the user's communication.

[0059] In Figure 6(c), the hiragana characters in the character display area 4200 are grouped and arranged within the respective colored frames, red frame 1510 and blue frame 1520, from right to left on the page. As shown in Figure 6(c), for example, the characters enclosed in the red frame 1510 include the hiragana characters from the "a-row," "ka-row," "sa-row," "ta-row," and "na-row," as well as the numbers 6, 7, 8, 9, and 0. Similarly, the blue frame 1520 includes the hiragana characters from the "ha-row," "ma-row," "ya-row," "ra-row," and "wa-row," as well as the numbers 1, 2, 3, 4, and 5, and punctuation marks.

[0060] In Figure 6(c), within the red large frame 1510 and the blue large frame 1520 of the character group display area 4200, the frame colors are classified into five vertical columns from left to right: light blue frame 1450, yellow frame 1440, green frame 1430, blue frame 1420, and red frame 1410, each forming a frame around an individual character. As shown in Figure 6(c), for example, the red frame 1410 of the red large frame 1510 contains the six characters "あ", "い", "う", "え", "お", and "0", and for example, the blue frame 1420 of the red large frame 1510 contains the six characters "か", "き", "く", "け", "こ", and "9", and similarly, each of the other frame colors contains any six characters or punctuation marks.

[0061] More specifically, in Figure 6, the "a" and "ha" rows are designated as red frames 1410, the "ka" and "ma" rows as blue frames 1420, the "sa" and "ya" rows as green frames 1430, the "ta" and "ra" rows as yellow frames 1440, and the "na" and "wa" rows as light blue frames 1450.

[0062] Furthermore, as shown in FIG. 6, each character type of the color-coded character board 4000 for communication is color-coded and displayed in each column using a color-coded font. For example, "あ" is displayed in a red font 1310, "い" is displayed in a blue font 1320, "う" is displayed in a green font 1330, "え" is displayed in a yellow font 1340, "お" is displayed in a light blue font 1350, and "0" is displayed in a purple font 1360. The same applies to the font colors of other columns, such as the "か row", "さ row",..., "は row", "ま row", etc. That is, for example, when a caregiver wants to select and transmit the character "あ", first, the red band 1110 is selected with the line of sight or finger pointing, etc. to transmit the large red frame 1510, then the red band 1110 is selected with the line of sight or finger pointing, etc. to transmit the red frame 1410, and then the red band 1110 is selected with the line of sight or finger pointing, etc. to transmit the red font 1310.

[0063] Similarly, for example, "わ" is displayed in a red font 1310, "を" is displayed in a blue font 1320, "ん" is displayed in a green font 1330, "、" is displayed in a yellow font 1340, "。" is displayed in a light blue font 1350, and "1" is displayed in a purple font 1360. That is, for example, when a caregiver wants to select and transmit the character "ん", first, the blue band 1120 is selected with the line of sight or finger pointing, etc. to transmit the large blue frame 1520, then the light blue band 1150 is selected with the line of sight or finger pointing, etc. to transmit the light blue frame 1450, and then the green band 1130 is selected with the line of sight or finger pointing, etc. to transmit the green font 1330. Also, 1140 is a yellow band, 1150 is a light blue band, and 1160 is a purple band. These color schemes, orders, and arrangements can be arbitrary ones suitable for the user.

[0064] And the occupied area of each of these color bands 1110 to 1160 is preferably larger than the occupied area of each individual character type shown in the character group display area 4200, so that the movement and fixation of the line of sight and finger pointing are easy and quick, and it is also easy for assistants, etc. to read, recognize, and grasp (or infer) it, reducing the time and effort required for mistakes and confirmation, and enabling accurate and quick communication of intentions.

[0065] As mentioned above, while it is acceptable for the same font color to be used multiple times between characters with different border colors, font colors should not be duplicated between characters within the same border color. If this duplication occurs, it becomes unclear which character is intended to be conveyed when a color is specified, resulting in the need for additional confirmation and selection. It is preferable that there are no duplicate colors at each stage of color selection, from the selection of the overall border color (broad concept) to the selection of border colors for each string (medium concept) and then to the selection of the font color (small concept), as these can cause confusion and hesitation.

[0066] In Figures 6(a), 6(c), and 6(d), the font color of the characters shown in the character group display area 4200, the frame color for each character string (corresponding to the first group frame), the color scheme and arrangement, and the overall color frame (corresponding to the second group frame) are the same as in the embodiment shown in Figure 6(c). Only the presence or absence and position of the color band 1100 differ, so no explanation is necessary. In the embodiment of Figure 6(b), the color band 1100 is not shown, but it is possible to provide the color band 1100 separately on a separate transparent substrate sheet, for example, separate from the color-coded character panel 4000 for communication. This also demonstrates certain effects of the present invention, as it enables the specification and transmission of each character solely through color selection and transmission.

[0067] In the example shown in Figure 6, a single character can be identified through three stages of color specification: a major conceptual color specification stage where the color of the second group border is specified; a medium conceptual color specification stage where the color of the first group border for each string is specified; and a minor conceptual color specification stage where the font color is specified. In each color specification stage, the desired color can be selected from the color bands arranged in the color selection area. The character grouping between the first and second group borders, their size, frame shape, and the number and types of characters placed within each frame can be arbitrarily adjusted and set to be user-friendly for the user.

[0068] The color-coded communication dial of the present invention is characterized by comprising, on a dial displaying multiple characters, a background and / or character frame for characters that are color-coded and grouped into at least two or more sets, and for each group, characters that are individually color-coded.

[0069] For example, the background color of each character on a dial displaying the hiragana characters "あ", "い", "う", etc., can be set to be different for each row, such as "あ", "か", and "さ". In addition, along with or instead of these color-coded character background groups, a colored frame can be provided for each character or group of characters to allow for color identification. Furthermore, by assigning a font color to each character, for example, each character in the "あ" row ("あ", "い", "う"), it becomes possible to specify the final character by color.

[0070] In other words, the system allows for the selection and specification of a single character by specifying colors in two or three stages: major category → minor category or major category → medium category → minor category. To enable use by those requiring assistance who are unable to pronounce colors, it is possible to provide color bands or color bars corresponding to the above color coding above, below, or both of the character groups, in an area larger than each character. Preferably, the system is configured so that the number of characters is largest in the major category, and decreases as it progresses to the medium and minor categories. Also preferably, the character board area occupied by the major category is largest, and decreases as it progresses to the medium and minor categories.

[0071] It is generally known that there are 46 hiragana characters in total, and including numbers and punctuation marks, the number reaches at least 60 or more. When these 60 or more characters are displayed on a dial, the display area for each character is extremely small. Therefore, it is often difficult to indicate or fix one's gaze on such a small area. However, if each character can be selected using two or three color settings, it becomes easier to indicate the desired character, leading to fewer errors and saving time.

[0072] Specifically, the character board is divided into three sections: the first 30 characters, including the "a" row, are enclosed in a red frame, and the latter 30 characters, including the "ha" row, are enclosed in a blue frame (major classification). Further inside, the entire "a" row is enclosed in a red frame, and the entire "ka" row is enclosed in a blue frame (medium classification). In addition, the character "a" is colored red, the character "i" in blue, the character "u" in green, and so on (minor classification). This allows users to quickly and accurately indicate their choice of "a" by first indicating "red" as the major classification (i.e., specifying the first 30 characters), then indicating "red" as the medium classification (i.e., specifying the "a" row), and finally indicating "red" as the minor classification (i.e., specifying "a").

[0073] The designations at each stage, from broad categories to subcategories, are simply color types; for example, six colors in total would suffice. Therefore, to select these six colors, color bands or color selection bars can be provided around the 60 characters, and since the selection area is for six colors, each can occupy a large area. Furthermore, the color bands or color selection bars may be prepared separately from the 60 character dial. In any case, the display area occupied by each color can be made considerably larger than the display area occupied by a single character, making selection easier, more accurate, and faster.

[0074] Furthermore, the color-coded communication dial of the present invention is characterized by comprising, on a dial displaying multiple characters, character outlines that are grouped into at least two or more groups and displayed in different colors, and character backgrounds that are individually color-coded for each group and each character.

[0075] For example, on a keyboard displaying the letters "A," "B," "C," etc., the background of each letter can be divided into blocks based on their arrangement, and "Q," "W," "A," "S," "Z," and "X" can be grouped together and enclosed in a red border, with each block having a different border color. Preferably, in addition to these color-coded groups of letter borders (major classifications), color borders can also be provided for other groups of smaller letters (medium classifications) to further distinguish them by color. Furthermore, by assigning individual background colors to each letter, for example "Q," "W," "A," "S," "Z," and "X" (minor classifications), it becomes possible to specify the final letter by color.

[0076] In other words, the system allows for the selection of individual characters by color, using a two-stage process of broad category → subcategory, or a three-stage process of broad category → medium category → subcategory, ultimately enabling the selection and specification of a single character on the character board. To ensure usability even for those requiring assistance who cannot articulate colors, color bands or bars corresponding to the above color coding can be placed above, below, or both of the character groups, or in the empty spaces to the left or right, occupying an area larger than each character. More specifically, the area occupied by a red band can be considerably larger than the area occupied by a single English letter, such as "A".

[0077] It is generally known that there are 26 letters in the English alphabet, and including numbers, symbols, and punctuation marks, the total number of characters reaches at least 40 or more. When these 40 or more characters are displayed on a dial, the display area per character becomes extremely small. As a result, it is often difficult to indicate or fix one's gaze on such a small area. However, if each character can be selected using two or three color settings, it becomes easier to indicate the desired character, leading to fewer errors and saving time. While the number of colors used for such selection is arbitrary, typically six colors are sufficient.

[0078] Specifically, the keyboard display will have a blue border around the characters "E," "R," "D," "F," "C," and "V" from the total of 40 or more characters (major categories). Furthermore, the character "E" will have a red background, the character "R" will have a blue background, the character "D" will have a green background, and so on (minor categories). This allows users to first indicate their preference for "blue" as the major category (i.e., designating the blue-bordered block), and then indicate their preference for "red" as the minor category (i.e., designating the red-backgrounded "E"), enabling them to quickly and accurately select "E."

[0079] The designations at each stage, from broad categories to subcategories, are simply color types; for example, six colors in total would suffice. Therefore, to select these six colors, color bands or color selection bars can be provided around the 40 characters, and since the selection area is for six colors, each can occupy a large area. Furthermore, the color bands or color selection bars may be prepared separately from the 40-character character dial. In any case, the display area occupied by each color can be made considerably larger than the display area occupied by a single character, making selection easier, more accurate, and faster.

[0080] Furthermore, the color-coded communication dial of the present invention is preferably characterized in that the character enclosing frame comprises at least a first group enclosing frame that encloses multiple characters as a first group and associates them with a single color, and a second group enclosing frame that encloses a larger second group, formed by bundling multiple first group enclosing frames, and associates them with a single color.

[0081] In other words, the character border can be divided into two levels: a first-group border that surrounds smaller groups with a single color, and a second-group border that surrounds larger groups with a single color. Specifically, for example, in a character display showing the Japanese syllabary, the rows "a", "ka", "sa", "ta", and "na" can be treated as one block, and these five rows are surrounded by a red border (this is a major classification and typically corresponds to a second-group border).

[0082] Furthermore, within the block of the major category, each character in the "a" row is enclosed in red, each character in the "ka" row in blue, each character in the "sa" row in green, each character in the "ta" row in yellow, and each character in the "na" row in light blue, creating a double color-coded frame (medium category). Preferably, individual font colors or background colors can also be set for each character. By changing the size of the population in this way and setting multiple levels of color frames, the number of colors used for identification can be reduced, making it possible to use only colors that are easy for users to see and identify, thus enabling easier expression of choice.

[0083] Furthermore, the color-coded communication dial of the present invention is more preferably characterized in that the characters include at least one of the following: alphabet, hiragana, katakana, symbols, numbers, or custom characters.

[0084] The characters displayed on the color-coded communication dial can include commonly used letters and numbers (which may be labeled as "Number" or "Number" to lower the display level), as well as custom phrases (such as toilet, bath, hungry, wash, suction, etc.). Even in this case, using the dial of the present invention, the selection of which characters to display can be individually specified by color alone.

[0085] Furthermore, the color-coded communication dial of the present invention is more preferably characterized by comprising a color selection area intended solely for selecting a color corresponding to the color coding.

[0086] On a color-coded communication dial, areas can be provided in the empty spaces above, below, above and below, and to the left and right of the characters to indicate colors for eye movement or pointing. Such color selection areas can be represented, for example, by color bands corresponding to each of the six colors. Since the number of colors is overwhelmingly small compared to the total number of characters, it is possible to allocate a large display area (occupied area) to each color.

[0087] Therefore, when users communicate their color selection preferences, they only need to specify the color that occupies the largest area, making it easier to select a color. The recipient can also more reliably, accurately, and easily understand the selected color. A separate color specification plate, such as a transparent resin plate, can be prepared for color selection, in addition to the main dial.

[0088] Furthermore, the color-coded communication dial of the present invention is more preferably characterized in that each color selection area has a larger occupied area than each display area of ​​the characters.

[0089] While the number of colors is arbitrary, if, for example, six colors are used, then having an area capable of displaying six colors is sufficient. By utilizing the empty space above and below where text is displayed, it is possible to secure a considerably larger display area for each color, making color selection easier and enabling accurate and rapid communication of color choices.

[0090] Furthermore, the color-coded communication dial of the present invention is more preferably characterized in that the color selection area is a color band or color strip positioned above and / or below the display area of ​​characters.

[0091] Since the colored band occupies a considerable area, it makes it easier to fix the user's gaze and point, reducing concerns about errors and confusion. The colored band can be placed above, below, or both above and below the text display area, or it can be placed in the empty space to the left or right of the text display area.

[0092] Furthermore, the method for transmitting selected characters using the color-coded communication dial of the present invention comprises a first color selection stage in which any color is selected from colors displayed in color coding in groups of at least two or more, and a second color selection stage in which any color is selected from the colors of individually color-coded characters, wherein the color selected in each stage corresponds to the color of the character to be selected.

[0093] In the first color selection stage, a larger group can be specified, and in the second color selection stage, smaller groups or individual characters can be selected individually. For both users and caregivers, the interaction becomes "color only," and regardless of the length or complexity of the message to be conveyed, it is greatly simplified, reducing communication errors and making communication easier, which in turn improves the speed of communication. Furthermore, as shown in the example, the number of colors can be reduced to about six, so it is possible to use only any preferred and easily distinguishable colors.

[0094] Furthermore, the method for transmitting selected characters using the color-coded character dial for communication of the present invention comprises a first color selection step of selecting any color from colors displayed in color coding in groups of at least two or more, and a second color selection step of selecting any color from the background colors of individually color-coded characters, wherein the color selected in each step corresponds to the color of the character to be selected.

[0095] In this case as well, a larger group can be specified in the first color selection stage, and a smaller group or individual letters can be selected and specified individually in the second color selection stage. Similarly, for both users and caregivers, the interaction becomes "color only," and is greatly simplified regardless of the length or complexity of the message to be conveyed. This reduces communication errors and makes communication easier, resulting in improved communication speed. Furthermore, as shown in the example, the number of colors can be reduced to about six, so it is possible to use only any preferred and easily distinguishable colors.

[0096] Furthermore, the method of communicating selected characters using the color-coded character board for communication of the present invention is preferably characterized in that the selection of a color is made by one or more of the following: the caregiver reads and estimates the target of the fixed gaze, or by uttering the words aloud, or by pointing.

[0097] Conventionally, well-known methods of communicating selected characters using a communication character board include the type in which the caregiver reads and estimates the target of the user's gaze, or the caregiver speaks the words aloud, or points to the target. The present invention is applicable to any of the three types described above, and the effects and benefits of each are obtained. Of course, within the scope of the technical concept of the present invention, those skilled in the art can appropriately apply, utilize, or adapt it to other methods and types.

[0098] Furthermore, the method for transmitting selected characters using the color-coded communication dial of the present invention is more preferably characterized in that the color-coded communication dial includes a color selection area intended solely for selecting a color corresponding to the color coding, and the target for fixing the movement of the gaze or the target for pointing is relative to the color selection area.

[0099] The color selection area can display, for example, six colors, each with a corresponding area, arranged in a display format such as a color band or stripe. Users can select and arrange only the colors that are easy to distinguish and see. It is also possible to provide a color selection area alongside the text, but it is preferable to display the color selection area larger and more clearly separated from the top, bottom, left, and right edges of the text placement area. Since individual text can be selected solely by color, the colors selected using the color selection area are extremely important.

[0100] Furthermore, the method for transmitting selected characters using the color-coded character dial for communication of the present invention is more preferably characterized in that each color selection area has a larger occupied area than each display area of ​​the characters.

[0101] On a character display that can contain dozens of characters, the area that each character can occupy is severely limited. This area is far from sufficient for fixed eye movement and pointing. On the other hand, the color identification area that can be displayed in the empty space around the characters can be limited to, for example, six colors, and it becomes possible to allocate a relatively large display area for each color. This reduces errors in communicating choices and enables smoother communication.

[0102] Furthermore, the method for transmitting selected characters using the color-coded character dial for communication of the present invention is more preferably characterized in that the color selection area is a color band or color strip positioned above and / or below the display area of ​​the characters.

[0103] A typical example of a color selection area is, as described in the embodiment, a color band or strip that is larger than the display area of ​​individual characters. Such a color band or strip may be provided on the periphery of a single color-coded communication dial together with the characters, or it may be provided on a separate transparent plate or the like, separate from the dial. In this case, the communication dial can be used as a set of two plates: a character display plate and a color selection plate.

[0104] (Example of custom display using 4-color coding) In this embodiment, we will illustrate and explain a communication board that enables even those who have not mastered various characters such as hiragana, katakana, English, kanji, or Japanese to communicate their intentions to a third party. In other words, the customization described here may include one or more of the following, as already explained: designs, logos, symbols, marks, pictures, motifs, images, videos, three-dimensional images, three-dimensional videos, emojis, words, sentences, holograms, etc., and may be used to express or communicate to a third party the user's thoughts or inner feelings such as emotions, desires, intentions, or instructions.

[0105] For individuals with language or physical impairments, particularly those who use gestures and body language, using such communication boards may be their only means of communicating with the outside world. Furthermore, even among able-bodied individuals, linguistic barriers often make smooth communication difficult. In such cases, communication can be facilitated through various marks and designs. The shape and structure of the communication board can be freely chosen.

[0106] For example, it may be constructed as a flat paper or plastic resin communication board, or as an electrical / electronic display panel or flat panel such as an LCD panel or organic EL display, or as a hologram display panel capable of projecting and presenting three-dimensional shapes. In the case of three-dimensional projection, a configuration such as so-called air selection buttons (non-contact space touch or virtual space touch) that allow buttons to be pressed or selected without direct contact may be adopted, or an AI (artificial intelligence) configuration that accurately anticipates the user's intentions or infers intentions from their gaze or slight movements may be adopted. Furthermore, a method of using so-called avatars to perform arbitrary actions, instructions, or communication may be adopted. For users with limitations on physical movement, communication using avatars is particularly effective. In addition, if the communication board is in an electronic / electrical form, it may be equipped with, for example, a wireless communication unit, an AI processing unit, an information processing unit (data processing unit), a storage unit, a display control unit, etc. Alternatively, the AI ​​processing unit, information processing unit, memory unit, etc., may be configured separately from the communication board itself, and display data information, etc., may be received and displayed via data communication by the wireless communication unit. Wired communication may be used instead of wireless communication.

[0107] The AI ​​may prioritize selecting the option most likely to express the user's intention at that moment, based on the user's eye movements, hand movements, accumulated data, and the user's current state, and display it in an easily accessible location. To achieve this, the communication board may be equipped with a camera and / or sensors to detect the user's eye movements and actions, artificial intelligence (AI) to analyze and process the data acquired from the camera and / or sensors, and a display function that can flexibly display the processing results in two or three dimensions.

[0108] The color coding of communication symbols displayed on the communication board can be done in three ways: the color of the symbol itself (typically the font color), the background color of the symbol, or the color of the border around the symbol. By choosing any of these three methods, it becomes possible to select a specific symbol for a particular purpose and communicate using only the color. For example, a total of four colors such as red, blue, green, and purple may be used. The grouping or categorization of each color can be vertical, horizontal, or any other arrangement. Communication symbols can be, for example, a shower symbol, a toilet symbol, or a food symbol (restaurant or knife and fork). The border color of the communication symbol can be set individually for each symbol, or multiple communication symbols can be grouped together and a group border color can be set for the group.

[0109] (Description of drawings relating to additional embodiments) Figure 11 illustrates an example of a communication board configuration that uses no background color (i.e., no background color), with four colors used for the border color of the communication symbols and four colors used for the communication symbols themselves. Figure 11(a) shows an example where color selection bars (color bands) are placed above and below the symbol placement area, while Figure 11(b) illustrates an example without color selection bars (color bands). The number of colors used in this communication board is essentially arbitrary, and any number of colors can be freely used to create the configuration. As already explained, the word "custom" in the figure means that any communication symbols such as designs or logos can be written or displayed there.

[0110] As shown in Figure 11(a), the red selection bar 11110 and the blue selection bar 11120 are displayed horizontally above the communication symbol display area, and the green selection bar 11130 and the purple selection bar 11160 are displayed horizontally below the communication symbol display area. In addition, the red frame 11410 is displayed as a surrounding frame for the four communication symbols, in order from the top of the leftmost vertical column: the red symbol 11310 (custom 1), the blue symbol 11320 (custom 5), the green symbol 11330 (custom 9), and the purple symbol 11360 (custom 13).

[0111] Additionally, the blue frame 11420 will be displayed as a border around the four communication symbols in the second column from the left, in order from top to bottom: the red symbol 11310 (custom 2), the blue symbol 11320 (custom 6), the green symbol 11330 (custom 10), and the purple symbol 11360 (custom 14). Furthermore, the green frame 11430 will be displayed as a border around the four communication symbols in the third column from the left, in order from top to bottom: the red symbol 11310 (custom 3), the blue symbol 11320 (custom 7), the green symbol 11330 (custom 11), and the purple symbol 11360 (custom 15). The purple frame 11460 is displayed as a border around the four communication symbols in the rightmost vertical column, from top to bottom: the red symbol 11310 (custom 4), the blue symbol 11320 (custom 8), the green symbol 11330 (custom 12), and the purple symbol 11360 (custom 16). In other words, in the example shown in Figure 11(a), four borders of the same color are arranged vertically, and four communication symbols of the same color are arranged horizontally. For example, a user can first select the blue selection bar 11120 as the frame color to narrow down their intention to select one of the communication symbols with the blue frame 11420 (custom 2, 6, 10, or 14), and then select the green selection bar 11130 to select the green symbol 11330, which is custom 10.

[0112] Furthermore, in Figure 11(b), the red frame 11410 is displayed as a surrounding frame for the four communication symbols in the leftmost column, from top to bottom: the red symbol 11310 (custom 1), the blue symbol 11320 (custom 5), the green symbol 11330 (custom 9), and the purple symbol 11360 (custom 13). In this example, since the space area of ​​the color selection bar is not required, it is possible to increase the area occupied by each communication symbol.

[0113] Furthermore, in Figure 11(b), the blue frame 11420 is displayed as a border around the four communication symbols in the second column from the left, in order from top to bottom: the red symbol 11310 (custom 2), the blue symbol 11320 (custom 6), the green symbol 11330 (custom 10), and the purple symbol 11360 (custom 14). Additionally, the green frame 11430 is displayed as a border around the four communication symbols in the third column from the left, in order from top to bottom: the red symbol 11310 (custom 3), the blue symbol 11320 (custom 7), the green symbol 11330 (custom 11), and the purple symbol 11360 (custom 15). The purple frame 11460 is then displayed as a border around the four communication symbols in the rightmost vertical column, from top to bottom: the red symbol 11310 (custom 4), the blue symbol 11320 (custom 8), the green symbol 11330 (custom 12), and the purple symbol 11360 (custom 16). In other words, in the example shown in Figure 11(b), four borders of the same color are arranged vertically, and four communication symbols of the same color are arranged horizontally. For example, by first selecting the blue frame 11420 (or blue) as the frame color, the user can narrow down their intention to select one of the custom communication symbols with the blue frame 11420 (custom 2, 6, 10, or 14), and then by selecting the green symbol 11330 (or green), they can select custom symbol 10, which is the green symbol 11330. Such color schemes and arrangements can be freely designed to be user-friendly.

[0114] Figure 12 illustrates an example of a communication board configuration where the background color of the communication symbols and the color of the communication symbols themselves are used to create four different colors, without using the border color of the communication symbols (i.e., no border color). Figure 12(a) shows an example where the color selection bar is placed at the top of the symbol placement area, and Figure 12(b) shows an example where the color selection bar is placed at the bottom of the symbol placement area.

[0115] As shown in Figure 12(a), the red selection bar 11110, the blue selection bar 11120, the green selection bar 11130, and the purple selection bar 11160 are displayed horizontally from left to right above the communication symbol display area. In addition, the red background 11210 is set as the background color for the four communication symbols in the top horizontal row from left to right: the red symbol 11310 (custom 1), the blue symbol 11320 (custom 2), the green symbol 11330 (custom 3), and the purple symbol 11360 (custom 4).

[0116] Additionally, the blue background 11220 is set as the background color for four communication symbols in the second row from the top, from left to right: red symbol 11310 (custom 5), blue symbol 11320 (custom 6), green symbol 11330 (custom 7), and purple symbol 11360 (custom 8). Furthermore, the green background 11230 is set as the background color for four communication symbols in the third row from the top, from left to right: red symbol 11310 (custom 9), blue symbol 11320 (custom 10), green symbol 11330 (custom 11), and purple symbol 11360 (custom 12). The purple background 11260 is then set as the background color for the four communication symbols located at the bottom of the horizontal row, from left to right: the red symbol 11310 (custom 13), the blue symbol 11320 (custom 14), the green symbol 11330 (custom 15), and the purple symbol 11360 (custom 16). In other words, in the example shown in Figure 12(a), four backgrounds of the same color are arranged horizontally, and four communication symbols of the same color are arranged vertically. For example, by first selecting the blue selection bar 11120 as the background color, the user can narrow down their intention to select one of the custom communication symbols 5, 6, 7, or 8 with the blue background color 11220. Then, by selecting the green selection bar 11130, they can select custom symbol 7, which is the green symbol 11330.

[0117] Furthermore, Figure 12(b) is identical to the description in Figure 12(a), except that the color selection bars 11110, 11120, 11130, and 11160 are located below the area where the communication symbols are placed. Therefore, to avoid repetition, the explanation is omitted here.

[0118] Figure 13 shows an example where the color of the communication symbol itself is constant (typically black), and the colors are grouped by the color of the communication symbol's border (vertically arranged with the same border color) and the background color (horizontally arranged with the same background). Figure 13(a) shows an example where color selection bars (color bands) are placed above and below the symbol placement area, while Figure 13(b) illustrates an example without color selection bars (color bands).

[0119] As shown in Figure 13(a), the red selection bar 11110 and the blue selection bar 11120 are displayed horizontally above the communication symbol display area, and the green selection bar 11130 and the purple selection bar 11160 are displayed horizontally below the communication symbol display area. In addition, the red frame 11410 is displayed as a surrounding frame for the four communication symbols in the leftmost vertical column, from top to bottom: red background 11210 (custom 1), blue background 11220 (custom 5), green background 11230 (custom 9), and purple background 11260 (custom 13). Note that in Figure 13, the color of the communication symbols can be displayed in any arbitrary color (for example, black or white).

[0120] Additionally, the blue frame 11420 is displayed as a border around the four communication symbols in the second column from the left, in order from top to bottom: red background 11210 (custom 2), blue background 11220 (custom 6), green background 11230 (custom 10), and purple background 11260 (custom 14). Furthermore, the green frame 11430 is displayed as a border around the four communication symbols in the third column from the left, in order from top to bottom: red background 11210 (custom 3), blue background 11220 (custom 7), green background 11230 (custom 11), and purple background 11260 (custom 15). The purple frame 11460 is then displayed as a border around the four communication symbols in the rightmost vertical column, from top to bottom: red background 11210 (custom 4), blue background 11220 (custom 8), green background 11230 (custom 12), and purple background 11260 (custom 16). In other words, in the example shown in Figure 13(a), four borders of the same color are arranged vertically, and four symbol backgrounds of the same color are arranged horizontally. For example, a user can first select the blue selection bar 11120 as the frame color to narrow down their intention to select one of the communication symbols with the blue frame 11420 (custom 2, 6, 10, or 14), and then select the green selection bar 11130 to select custom 10, which has a green background 11230.

[0121] Furthermore, in Figure 13(b), the red frame 11410 is displayed as a border around the four communication symbols in the leftmost column, from top to bottom: red background 11210 (custom 1), blue background 11220 (custom 5), green background 11230 (custom 9), and purple background 11260 (custom 13). In this example, since the space area of ​​the color selection bar is not required, it is possible to occupy a relatively large area for each communication symbol.

[0122] Furthermore, in Figure 13(b), the blue frame 11420 is displayed as a border around the four communication symbols in the second column from the left, in order from top to bottom: red background 11210 (custom 2), blue background 11220 (custom 6), green background 11230 (custom 10), and purple background 11260 (custom 14). Additionally, the green frame 11430 is displayed as a border around the four communication symbols in the third column from the left, in order from top to bottom: red background 11210 (custom 3), blue background 11220 (custom 7), green background 11230 (custom 11), and purple background 11260 (custom 15). The purple frame 11460 is then displayed as a border around the four communication symbols in the rightmost vertical column, from top to bottom: red background 11210 (custom 4), blue background 11220 (custom 8), green background 11230 (custom 12), and purple background 11260 (custom 16). In other words, in the example shown in Figure 13(b), four borders of the same color are arranged vertically, and four backgrounds of the same color are arranged horizontally. For example, by first selecting the blue frame 11420 (or blue) as the frame color, the user can narrow down their intention to select one of the custom 2, 6, 10, or 14 communication symbols with a blue frame 11420. Then, by selecting the green background 11230 (or green), they can select custom 10, which has a green background 11230. The color scheme, arrangement, and number of communication symbols can be freely designed to be user-friendly.

[0123] Figure 14 shows an example where the color of the communication symbols themselves is constant (typically black), and the colors are grouped by the color of the communication symbol's border (horizontally arranged with the same border color) and the background color (vertically arranged with the same background). Figure 14(a) shows an example where a color selection bar (color band) is placed above the symbol placement area, and Figure 14(b) illustrates an example where a color selection bar (color band) is placed above the symbol placement area.

[0124] As shown in Figure 14(a), the red selection bar 11110, the blue selection bar 11120, the green selection bar 11130, and the purple selection bar 11160 are displayed horizontally above the communication symbol display area. In addition, the red frame 11410 is displayed as a surrounding frame for the four communication symbols, from left to right in the topmost horizontal row: red background 11210 (custom 1), blue background 11220 (custom 2), green background 11230 (custom 3), and purple background 11260 (custom 4). Note that in Figure 14, the communication symbols can be displayed in a certain arbitrary color (for example, colorless black or white).

[0125] Additionally, the blue frame 11420 is displayed as a border around the four communication symbols in the second row from the top, from left to right: red background 11210 (custom 5), blue background 11220 (custom 6), green background 11230 (custom 7), and purple background 11260 (custom 8). Furthermore, the green frame 11430 is displayed as a border around the four communication symbols in the third row from the top, from left to right: red background 11210 (custom 9), blue background 11220 (custom 10), green background 11230 (custom 11), and purple background 11260 (custom 12). The purple frame 11460 is displayed as a border around each of the four communication symbols located at the bottom edge, from left to right in the horizontal row: red background 11210 (custom 13), blue background 11220 (custom 14), green background 11230 (custom 15), and purple background 11260 (custom 16). In other words, in the example shown in Figure 14(a), four borders of the same color are arranged horizontally, and four symbol backgrounds of the same color are arranged vertically. For example, by first selecting the blue selection bar 11120 as the frame color, the user can narrow down their intention to select one of the communication symbols with a blue frame 11420 (custom 5, 6, 7, or 8), and then by selecting the green selection bar 11130, they can select custom 7 with a green background 11230.

[0126] Furthermore, Figure 14(b) is identical to the description in Figure 14(a), except that the red selection bar 11110, the blue selection bar 11120, the green selection bar 11130, and the purple selection bar 11160 are shown side by side below the communication symbol display area. Therefore, to avoid duplication, the explanation is omitted here.

[0127] The communication board of the present invention is characterized by comprising, on a communication board on which a plurality of communication symbols are displayed, a background and / or a frame surrounding the communication symbols, which are displayed in color in groups of at least two or more, and for each group, individually displayed communication symbols, which are displayed in color. For example, the communication symbol background can be a total of four colors, and four of the total 16 communication symbols can be grouped into each background color, and then the four communication symbols for each background color can be displayed in four different colors.

[0128] This allows the user to first select "red" to specify the red group (which in the previous example includes four communication symbols), and then select "blue" from the four colored communication symbols grouped under red to choose one blue communication symbol. In other words, by repeating the process of selecting one color from four twice, it becomes easy to select the desired communication symbol.

[0129] Furthermore, the communication board of the present invention is characterized by comprising, on a communication board displaying multiple communication symbols, a color-coded border around communication symbols grouped into at least two or more groups, and a color-coded background around each communication symbol for each group. For example, the communication symbol background can be a total of four colors, with four of the 16 total communication symbols grouped into each background color, and then the four communication symbols for each background color can be color-coded with four different border colors. The border and background can be either on the outside or inside, but it is preferable to have the border on the outside as it is more user-friendly.

[0130] This allows the user to first select the "red" border color to specify a group of red borders (which in the previous example would contain four communication symbols), and then select "blue" from the four colored communication symbols grouped within that red border to choose one communication symbol with a blue background. In other words, by repeating the process of selecting one color from four twice, it becomes easy to select the desired communication symbol.

[0131] Furthermore, the communication board of the present invention is preferably characterized in that the communication symbols are individually color-coded for each group. While it is possible to display the communication symbols themselves in a single color, such as black, if the communication symbols themselves can be color-coded, it is preferable to color-code them so that the final color selection can be made more reliably.

[0132] Furthermore, the communication board of the present invention is more preferably characterized in that the communication symbols are for expressing or transmitting to a third party the user's thoughts or inner feelings such as emotions, desires, intentions, and instructions. In other words, the communication symbols are not limited to so-called letters or language, but can be any design, logo, emoji, symbol, three-dimensional display, sign, or billboard that allows users who have limitations in expressing their will, transmitting their intentions, communicating, or communicating with others to convey, instruct, empathize with, or express their will, feelings, instructions, thoughts, and emotions to those around them. Since human activities involve communication in all sorts of situations, anything that contributes to communication in various situations can be adopted and applied as a communication symbol.

[0133] Furthermore, the communication board of the present invention is more preferably characterized in that the communication symbols include one of the following: a design, logo, symbol, mark, picture, motif, image, video, 3D image, 3D video, emoji, word, or sentence. The examples shown herein are typical examples of communication symbols and are not limited thereto.

[0134] Furthermore, the communication board of the present invention is more preferably characterized in that the communication symbol enclosure frame comprises at least a first group enclosure frame that encloses a plurality of communication symbols as a first group and associating them with a single color, and a second group enclosure frame that encloses a larger second group, formed by bundling multiple first group enclosure frames, and associating them with a single color. This disclosure describes a configuration that includes an enclosure frame in a so-called two-tiered structure. For example, all 16 communication symbols can be grouped into groups of four and enclosed in red, blue, green, and purple enclosure frames, respectively. Then, the four communication symbols within each color group can be individually enclosed in red, blue, green, and purple enclosure frames, respectively. This makes it possible to easily select a single intended communication symbol by repeating the process of selecting one color from the four enclosure frames twice.

[0135] Furthermore, the communication board of the present invention is more preferably characterized by having a color selection area solely for the purpose of selecting a color corresponding to the color coding. When selecting a color, for example, if the selection is made by moving the eyes, it is conceivable that it may be difficult to distinguish between colors. However, by displaying, for example, a color bar for color selection at one or more locations on the top, bottom, left, or right of the area where the communication symbols are placed, it is expected that selection errors and discrimination errors will be reduced.

[0136] Furthermore, the communication board of the present invention is more preferably characterized in that each color selection area has a larger occupied area than each display area of ​​the communication symbol. This reduces errors in color selection and enables easier and more reliable color selection.

[0137] Furthermore, the communication board of the present invention is more preferably characterized in that the color selection area is a color band or color strip positioned above and / or below the display area for characters. Positioning it above, below, or both is expected to further enhance the shape and ease of handling of the communication board, such as in A4 landscape orientation.

[0138] Furthermore, the communication board of the present invention is more preferably characterized by using four colors, with a total of four colors that are distinctly identified from one another. This is preferable because even users who have not learned the characters or language, or who have learned them but use a different language or characters, can select the intended symbol by choosing any one of the four corresponding colors.

[0139] Furthermore, the communication method of the present invention is a communication method using the above-described communication board, and comprises a first color selection step in which a user selects an arbitrary color from the background and / or the frame color of the communication symbols, which are grouped into at least two or more color-coded groups, and a second color selection step in which a user selects an arbitrary color from the colors of the individually color-coded communication symbols, wherein the color selected in each step corresponds to the color of the communication symbol to be selected. This makes it possible to express intentions more easily, user-friendly, and reliable.

[0140] Furthermore, the communication method of the present invention is a communication method using the above-described communication board, and comprises a first color selection stage in which an arbitrary color is selected from the color-coded border colors, and a second color selection stage in which an arbitrary color is selected from the color-coded background colors, wherein the color selected in each stage corresponds to the color of the communication symbol to be selected. This makes it possible to express intentions more easily, user-friendly, and reliable.

[0141] Furthermore, the color-coded communication dial of the present invention is preferably characterized in that each color-coded group is arranged vertically or horizontally. That is, the color-coded characters and the like can be neatly displayed in a single horizontal or vertical row for each color. The appearance is clean and beautiful, and a clear and easy-to-read dial is achieved by eliminating clutter.

[0142] Furthermore, the communication board of the present invention is preferably characterized in that each color-coded group is arranged vertically or horizontally. That is, the color-coded communication symbols can be neatly displayed in a horizontal or vertical row for each color. The appearance is clean and beautiful, and the clutter is eliminated, resulting in a clear and easy-to-read dial.

[0143] Furthermore, the communication board of the present invention is characterized in that, in a communication board on which a plurality of communication symbols are displayed, the communication symbols are color-coded in at least two of three ways: the frame color surrounding the communication symbol, the background color of the communication symbol, and the symbol color of the communication symbol itself, and one of the two ways of color-coding is a vertical color arrangement, and the other is a horizontal color arrangement.

[0144] Typically, when using two color coding methods, the following combinations are possible: frame color (same color, vertically arranged) and background color (same color, horizontally arranged); frame color (same color, horizontally arranged) and background color (same color, vertically arranged); frame color (same color, vertically arranged) and text color (same color, horizontally arranged); frame color (same color, horizontally arranged) and text color (same color, vertically arranged); background color (same color, vertically arranged) and text color (same color, horizontally arranged); and background color (same color, horizontally arranged) and text color (same color, vertically arranged). Furthermore, for each of these methods, it is possible to consider whether or not to provide a color selection bar (color band), and if so, whether to provide it above, below, or both sides of the symbol placement area, or to provide it on the left side, right side, or both sides, and so on.

[0145] (Example of custom display using two color coding) Figure 15 illustrates an example of using two-color coding for frame color and background color (no symbol color) to create a custom display only (custom symbols are optional). (a) illustrates an example where the frame color is the same color and arranged vertically, and the background color is the same color and arranged horizontally, with color selection bars at the top and bottom. (b) illustrates an example where the frame color is the same color and arranged horizontally, and the background color is the same color and arranged vertically, with color selection bars on the left and right.

[0146] In Figure 15(a), the red selection bar 11110 is positioned at the top and the blue selection bar 11120 is positioned at the bottom. Custom 1 and Custom 3 are framed in red (11410), Custom 2 and Custom 4 are framed in blue (11420), and Custom 1 and Custom 2 have a red background (11210), while Custom 3 and Custom 4 have a blue background (11220). The method and order of selecting custom symbols are the same as those already explained, so the explanation is omitted here.

[0147] Furthermore, in Figure 15(b), the red selection bar 11110 is located on the left and the blue selection bar 11120 is located on the right. Custom 1 and Custom 2 are assigned a red frame 11410, Custom 3 and Custom 4 are assigned a blue frame 11420, and Custom 1 and Custom 3 have a red background 11210, while Custom 2 and Custom 4 have a blue background 11220. The method and order of selecting custom symbols are the same as those already explained, so the explanation is omitted here. In other words, a one-to-one combination set of frame color and background color is assigned to each custom symbol, and in the example in Figure 15, once one combination set of frame color and background color is determined, only one corresponding custom symbol can be selected.

[0148] (Example of custom display using 3-color coding) Figure 16 illustrates an example of using a three-color scheme with frame color and symbol color (no background color) for custom display only (custom symbols are optional). (a) illustrates an example where the frame color is the same color and arranged vertically, and the symbol color is the same color and arranged horizontally, with color selection bars at the top and bottom. (b) illustrates an example where the frame color is the same color and arranged horizontally, and the symbol color is the same color and arranged vertically, with a color selection bar only at the bottom.

[0149] In Figure 16(a), the red selection bar 11110 and the blue selection bar 11120 are located at the top, and the green selection bar 11130 is located at the bottom. Custom 1, Custom 4, and Custom 7 are represented by the red frame 11410, Custom 2, Custom 5, and Custom 8 by the blue frame 11420, and Custom 3, Custom 6, and Custom 9 by the green frame 11430. Furthermore, Custom 1, Custom 2, and Custom 3 are represented by the red symbol 11310, Custom 4, Custom 5, and Custom 6 by the blue symbol 11320, and Custom 7, Custom 8, and Custom 9 by the green symbol 11330. The method of selecting custom symbols and the order of selection are the same as those already explained, so the explanation is omitted here. Regarding the selection order, it is preferable to select from the outside inwards, towards the custom symbols, but it is not limited to this.

[0150] Furthermore, in Figure 16(b), the red selection bar 11110, the blue selection bar 11120, and the green selection bar 11130 are located at the bottom. Custom 1, Custom 2, and Custom 3 are represented by the red frame 11410, Custom 4, Custom 5, and Custom 6 by the blue frame 11420, and Custom 7, Custom 8, and Custom 9 by the green frame 11430. Additionally, Custom 1, Custom 4, and Custom 7 are represented by the red symbol 11310, Custom 2, Custom 5, and Custom 8 by the blue symbol 11320, and Custom 3, Custom 6, and Custom 9 by the green symbol 11330. The method and order of selecting custom symbols are the same as those already explained, so the explanation is omitted here. Regarding the selection order, it is preferable to select from the outside inwards, towards the custom symbols, to reduce errors, but this is not the only option. Each custom symbol is assigned a one-to-one combination of frame color and symbol color. In the example in Figure 16, once one color combination of frame color and symbol color is determined, only one corresponding custom symbol can be selected.

[0151] (Example of custom display using 5 color coding) Figure 17 illustrates an example of using five color coding for background and symbol colors (without border color) to create a custom display only (custom symbols are optional). (a) illustrates an example where the background color is the same color and arranged vertically, the symbol color is the same color and arranged horizontally, with a color selection bar at the top. (b) illustrates an example where the background color is the same color and arranged horizontally, the symbol color is the same color and arranged vertically, without a color selection bar.

[0152] In Figure 17(a), the red selection bar 11110, the blue selection bar 11120, the green selection bar 11130, the yellow selection bar 11140, and the purple selection bar 11160 are located at the top. Custom 1 through Custom 5 are represented by the red symbol 11310, Custom 6 through Custom 10 by the blue symbol 11320, Custom 11 through Custom 15 by the green symbol 11330, Custom 16 through Custom 20 by the yellow symbol 11340, and Custom 21 through Custom 25 by the purple symbol 11360. Furthermore, Custom 1, Custom 6, Custom 11, Custom 16, and Custom 21 have a red background (11210), Custom 2, Custom 7, Custom 12, Custom 17, and Custom 22 have a blue background (11220), Custom 3, Custom 8, Custom 13, Custom 18, and Custom 23 have a green background (11230), Custom 4, Custom 9, Custom 14, Custom 19, and Custom 24 have a yellow background (11240), and Custom 5, Custom 10, Custom 15, Custom 20, and Custom 25 have a purple background (11260). The method and order of selecting custom symbols are the same as those already explained, so the explanation will be omitted here. Regarding the selection order, selecting from the outside inwards, towards the custom symbols, is preferable to prevent confusion and ensure orderly and smooth selection, but it is not limited to this.

[0153] Furthermore, in Figure 17(b), no color selection bar is provided. Custom 1 through Custom 5 are set to a red background (11210), Custom 6 through Custom 10 are set to a blue background (11220), Custom 11 through Custom 15 are set to a green background (11230), Custom 16 through Custom 20 are set to a yellow background (11240), and Custom 21 through Custom 25 are set to a purple background (11260). Furthermore, Custom 1, Custom 6, Custom 11, Custom 16, and Custom 21 are red symbols 11310; Custom 2, Custom 7, Custom 12, Custom 17, and Custom 22 are blue symbols 11320; Custom 3, Custom 8, Custom 13, Custom 18, and Custom 23 are green symbols 11330; Custom 4, Custom 9, Custom 14, Custom 19, and Custom 24 are yellow symbols 11340; and Custom 5, Custom 10, Custom 15, Custom 20, and Custom 25 are purple symbols 11360. The method and order of selecting custom symbols are the same as those already explained, so the explanation will be omitted here. Regarding the selection order, it is preferable to select from the outside inwards, towards the custom symbols, to reduce errors, but this is not the only option. Each custom symbol is assigned a one-to-one combination of background color and symbol color. In the example in Figure 17, once one combination of background color and symbol color is determined, only one corresponding custom symbol can be selected.
