[1] Example FIG. 1 shows a hardware configuration of a display device 10 according to an embodiment. The display device 10 is a device provided with a display which is a display means and displays characters and images, and is, for example, a smartphone or a tablet terminal. The display device 10 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, a NIC (Network Interface Card) 14, a storage 15, and a touch screen 16. It is a computer equipped.

The CPU 11 controls the operation of each unit by executing a program stored in the ROM 13 or the storage 15 using the RAM 12 as a work area. The NIC 14 has a communication circuit and communicates with an external device. The storage 15 is a storage medium such as a flash memory, and stores data and programs used by the CPU 11 for control. The touch screen 16 includes a display and a touch panel provided on the surface of the display, displays characters and images, and accepts operations from the user.

By executing the program and controlling each part by the CPU 11, the functions described below are realized.
FIG. 2 shows a functional configuration realized by the display device 10. The display device 10 includes a list display control unit 101, an item identification unit 102, an abbreviated item determination unit 103, an index display control unit 104, an item selection operation reception unit 105, and an item correspondence processing unit 106.

The list display control unit 101 is a function of displaying a list of data on a display means (display of the touch screen 16 in this embodiment), and is an example of the “first display control unit” of the present invention. The list display control unit 101 contains, for example, a list of names, a list of telephone numbers, a list of thumbnails of photographs stored in the own device, a list of names of songs in which music data is stored in the own device, and the like. Display as a list. In this embodiment, a case where the list display control unit 101 displays a list of addresses as a list of data will be described.

The list display control unit 101 displays a list with characters of a size set as a visible character size. When the number of data is too large to be displayed on one screen, the list display control unit 101 scrolls the screen to display all the data. The list display control unit 101 supplies the data group (all data) to be displayed as a list to the item identification unit 102 and the abbreviated item determination unit 103.

The item specifying unit 102 specifies an item that divides the data displayed in the list by the list display control unit 101. In this embodiment, the item specifying unit 102 specifies the data displayed in the list, that is, the item corresponding to the sound (speech sound) at the beginning of the address as the item of those data. If the beginning of the address is represented by Japanese characters, the item specifying unit 102 specifies the hiragana in the A column of the line including the first sound as the item of the address.

For example, if the address is "Adachi-ku ...", the item identification unit 102 specifies "A" as an item because the first sound "A" is in the A-dan, and uses the address "Chiyoda-ku ...". If there is, specify "ta", which is the hiragana of A-dan in "ta line" including the first sound "chi", as an item. Further, when the head of the address is a number (for example, a zip code) or an alphabet, the item specifying unit 102 specifies the first character as it is as an item. The item specifying unit 102 supplies the specified item to the omitted item determining unit 103.

The index display control unit 104 causes the display means to display an item for dividing the data displayed in the list by the list display control unit 101 as an index of the data. The index display control unit 104 is an example of the second display control unit of the present invention. FIG. 3 shows an example of a list of displayed data and an index. In FIG. 3, the address book screen A1 is displayed on the touch screen 16. The address list B1, the scroll bar C1, and the index D1 are displayed on the screen A1. The list display control unit 101 displays the address list B1 and the scroll bar C1, and the index display control unit 104 displays the index D1 in the index display field H1.

In the example of FIG. 3, the addresses starting with "a", "i", "e", "o", and "ka" included in the address list B1 are displayed. The address list B1 includes addresses that are not displayed even after the address starting with "ka". When the user operates the scroll bar C1 to scroll the address list B1, the list display control unit 101 displays those undisplayed addresses. In addition, although only the first character of the address is represented by hiragana for the sake of clarity, the address may be represented by Chinese characters or numbers.

The index display control unit 104 supplies the displayed index information to the item selection operation reception unit 105. The index information is information that represents the displayed items and the position where those items are displayed (the position is represented by, for example, the coordinates on the screen). The item selection operation reception unit 105 receives an operation of a user who selects any item from the index displayed by the index display control unit 104. The item selection operation reception unit 105 is an example of the “reception unit” of the present invention.

FIG. 4 shows an example of how an item is selected. In the example of FIG. 4, it is shown that the user's finger E1 selects the item "na" in the index D1. The item selection operation receiving unit 105 identifies an item selected by the user from a position instructed by the user, and accepts an operation of selecting the specified item. The item selection operation reception unit 105 supplies the items selected by the received operation to the index display control unit 104 and the item correspondence processing unit 106.

The item correspondence processing unit 106 performs processing according to the item selected by the operation received by the item selection operation reception unit 105. The item-corresponding processing unit 106 is an example of the “processing unit” of the present invention. In this embodiment, the item correspondence processing unit 106 performs a process of displaying the data classified into the selected items on the list display control unit 101 as a process corresponding to the selected item. By performing this processing by the item correspondence processing unit 106, in the example of FIG. 4, the list display control unit 101 displays the address starting with "na" as the address list B1.

Further, the item correspondence processing unit 106 performs a process of displaying an enlarged image representing the selected item in an enlarged manner on the display means as a process corresponding to the selected item. In the example of FIG. 4, the item correspondence processing unit 106 displays an enlarged image F1 that enlarges and represents the selected item “na”. In the case of a touch screen, the item instructed by the user is hidden by the user's finger E1, but the enlarged image F1 is displayed so that the user grasps the item selected by the user.

The items included in the index D1 shown in FIG. 3 are the hiragana group G1 "Akasata nahamayarawa", the number group G2 represented by the character string "12 #", and the character string "AZ #". It is classified into a plurality of groups called the group G3 of the alphabet represented by. "12 #" and "AZ #" do not represent the items "1", "2", "A", and "Z", respectively, but the items of groups G2 and G3 are omitted. It is a character string to indicate. As described above, in the example of FIG. 3, the items included in the groups G2 and G3 are omitted. Which item is omitted is determined by the omitted item determination unit 103.

The abbreviated item determination unit 103 displays in the index when the item for classifying the data displayed in the list by the list display control unit 101 (hereinafter referred to as “list display data”) is displayed as an index of the list display data. Determine the items to be omitted (hereinafter referred to as "abbreviated items"). The abbreviation item determination unit 103 is an example of the "determination unit" of the present invention.

When the item determined by the abbreviated item determination unit 103 is supplied to the index display control unit 104, the index display control unit 104 omits the item determined by the abbreviated item determination unit 103 and causes the display means to display the index. In the example of FIG. 3, the abbreviation item determination unit 103 determines all the items included in the groups G2 and G3 as abbreviated items. The index display control unit 104 displays all the items other than the labor-saving items without scrolling. This abbreviated item is an example, and other items may be determined as an abbreviated item. The specific method for determining the abbreviated items will be described below.

In this embodiment, the abbreviation item determination unit 103 determines the abbreviation item according to five rules. The abbreviated item determination unit 103 determines the abbreviated item when the number of items of the list display data is the threshold value Th1 or more according to the first rule. In other words, the abbreviated item determination unit 103 does not determine the abbreviated item when the number of items in the list display data is less than the threshold value Th1. As the threshold value Th1, for example, the number of lines when each item is displayed in the display column of the index with characters having a size easily visible on the display device 10 (12 lines in the case of the display column H1 in FIG. 3) is used.

FIG. 5 represents an example of an index displayed according to the first rule. In the example of FIG. 5, the touch screen 16 displays an address list B2 including an address whose first character is "a", "ku", "shi", "to", "ma", and "T". There is. The abbreviated item determination unit 103 does not determine the abbreviated item because "6", which is the number of items of the list display data shown in FIG. 5, is less than "12" of the threshold value Th1. Therefore, the index display control unit 104 sets each item in the index D2 including all the items of the list display data (“a”, “ka”, “sa”, “ta”, “ma”, “T”). They are displayed side by side at a common interval. As described above, when the number of items of the list display data is less than the threshold value Th1, that is, when the number of items of the list display data is small, all the items are displayed.

When the number of items of the list display data is the threshold value Th1 or more, the abbreviated item determination unit 103 determines as many items as the omitted items as the number of items of the list display data increases according to the second rule. For example, when the list display data includes only the address whose first character is the alphabet, the abbreviation item determination unit 103 determines that the number of items in the list display data is "13", which exceeds the threshold Th1 "12". The item "1" is determined as an abbreviated item, and if the number of items is "20", the item "8" is determined as an abbreviated item.

That is, in this example, the abbreviated item determination unit 103 determines the item of the number of differences between the number of items of the list display data and the threshold value Th1 as the abbreviated item. As a result, the number of items displayed as an index is smaller than when all the items are displayed as an index, and each item is displayed in large characters, which makes it easier for the user to understand the displayed items. In addition, by using other rules described later, more items than the number of differences mentioned above may be determined as omitted items, but if it is not necessary to make the characters representing the items smaller, they are omitted. It doesn't matter if the number of items increases.

The abbreviation item determination unit 103 determines which item is actually omitted according to the third, fourth, and fifth rules. First, the abbreviated item determination unit 103 determines as an abbreviated item an item for which there is no data classified into its own item in the list display data according to the third rule. FIG. 6 represents an example of an index displayed according to the third rule. In the example of FIG. 6, on the touch screen 16, among the items of the alphabet of the group G3, "A", "B", "D", "E", "G", "H", "O", "R" , "T", index D3 including "Z", and address list B3 including addresses beginning with "H", "O", "R", "T", "Z" are displayed. Has been done.

In this example, the abbreviated item determination unit 103 determines an address item whose first character is "I", "J", "K", etc., which is not included in the address list B3, as an abbreviated item. By displaying the index D3 in which the items are omitted in this way, the user can grasp the items in which the data classified into the own items exist in the list data.

Further, the abbreviated item determination unit 103 determines the item of the group in which the item of the data currently not displayed in the list display data is classified as the abbreviated item according to the fourth rule. For example, in the index D1 shown in FIG. 3, the items determined according to this third rule are omitted. In the abbreviation item determination unit 103, the address currently displayed in the address list B1 which is the list data is the address whose head is the sound from "a" to "ka", and the address whose head is a number and an alphabet. Is not displayed, so the items of groups G2 and G3 in which the items of those addresses are classified are determined as omitted items.

When omitting a group item, the abbreviation item determination unit 103 determines a predetermined item among the items included in the group as an abbreviated item in this embodiment. For example, in the case of the number group G2, the items from "0" to "9" are determined, and in the case of the alphabet group G3, the items from "A" to "Z" are determined. By omitting the items of the groups G2 and G3 in this way, the user grasps the items of the group G1, that is, the group in which the currently displayed items are classified, as compared with the case where the items are omitted regardless of the group. It's getting easier.

When the user selects the item of the group G1 of the index D1 shown in FIG. 3 and lowers the selection position, the item of the group G2 is selected next to the last item of the group G1 called "wa". .. FIG. 7 shows an example of an index displayed when the group of selected items is switched. In the example of FIG. 7, the item of the group G1 is abbreviated as "red #", and all the items from "0" to "9" of the group G2 are displayed.

In the example of FIG. 7, since the user's finger E1 has moved to the position where the character string indicating that the item of the group G2 "12 #" is omitted in FIG. 3 is displayed, all of them are displayed. Among the items of the group G2, "9" closest to the character string (AZ #) indicating that the item of the group G3 is omitted is selected. As a result, among the addresses included in the address list B1, the list display control unit 101 displays the addresses having the numbers from "6" to "9" including "9" as the first character.

In this way, the abbreviated item determination unit 103 changes the abbreviated item when the group in which the item selected by the operation received by the item selection operation receiving unit 105 among the indexes displayed by the index display control unit 104 is switched is switched. The groups to be classified are also switched to determine the omitted items. In the example of FIG. 7, the abbreviation item determination unit 103 switches the group in which the abbreviation items are classified from the group G2 to the group G1 and determines the hiragana item classified in the group G1 as the abbreviation item.

In addition, the order of the items (hiragana, numbers, alphabets) that divide the list display data in this embodiment is determined. Therefore, the abbreviated item determination unit 103 determines as many items as the abbreviated items as the items in the list display data are farther from the currently displayed data items in accordance with the fifth rule.

FIG. 8 represents an example of an index displayed according to the fifth rule. In the example of FIG. 8, on the touch screen 16, the address whose first character is "R", "S", "T", "W", and "Z" included in the address list B4 and the alphabet of the group G3 are displayed. Among the items, the index D4 including the items "M", "N", "O", "P", "R", "S", "T", "W", and "Z" is displayed. .. It is assumed that the address list B4 also includes, for example, an address whose first character is an alphabet from "A" to "Q".

In this example, the abbreviated item determination unit 103 determines, among the items of the alphabet of the group G3, the items before "M" as the abbreviated items. In addition, the abbreviated item determination unit 103 also follows the second rule, and the item (“Q”, “U”, “V”, “X” in this example) that does not have data classified into its own item in the list display data. , "Y") is also determined as an abbreviated item.

In the example of FIG. 8, the index display control unit 104 uses the character string "AB #" indicating that the item at the beginning of the alphabet is omitted instead of the item of the alphabet omitted according to the fourth rule. It is displayed. By displaying the index D4 in which the items are omitted in this way, it is easier for the user to grasp the items in the order closer to the items of the list display data currently displayed.

The display device 10 includes the above-mentioned configuration, and performs an index display process for displaying an index omitting items and an item correspondence process corresponding to the selected item when the item included in the index is selected. conduct. FIG. 9 shows an example of the operation procedure of the display device 10 in the index display process. This operation procedure is started when the user performs an operation to display a list of data (for example, an address book shown in FIG. 3). First, the display device 10 (list display control unit 101) controls the display means to display a list of data (step S11).

In parallel with the operation of step S11, the display device 10 performs the operations from steps S21 to S23. First, the display device 10 (item specifying unit 102) specifies an item for classifying the list display data displayed in the list by the list display control unit 101 (step S21). Next, when the item for dividing the list display data is displayed as an index of the list display data, the display device 10 (abbreviated item determination unit 103) determines the omitted item in the index (step S22). Then, the display device 10 (index display control unit 104) uses the item for dividing the data displayed in the list by the list display control unit 101 as an index of the data, omitting the item determined in step S22, and displaying means. Is controlled to be displayed in (step S23).

FIG. 10 shows an example of the operation procedure of the display device 10 in the item correspondence process. This operation procedure is started when the user selects one of the items from the displayed index. First, the display device 10 (item selection operation receiving unit 105) accepts an operation for selecting an item (step S31).

Next, the display device 10 (item correspondence processing unit 106) controls the display means to display the data classified into the selected items (step S32). By this operation, for example, in the example of FIG. 4, the address starting with "na" or "ni" classified into the selected item "na" is displayed. The display device 10 (item correspondence processing unit 106) controls to display the enlarged image of the selected item on the display means in parallel with the operation of step S32 (step S33). By this operation, for example, in the example of FIG. 4, an enlarged image F1 in which the selected item "na" is enlarged is displayed.

[2] Modifications The above-mentioned examples are merely examples of the implementation of the present invention, and may be modified as follows. Further, the examples and the modified examples may be combined and carried out as necessary.

[2-1] Method of determining omitted items 1
The abbreviation item determination unit 103 does not have to follow all five rules described in the examples. The abbreviated item determination unit 103 may determine the abbreviated item only according to, for example, the first to fourth rules, or may determine the abbreviated item only according to the second rule. The abbreviation item determination unit 103 may determine the abbreviation item according to one or more of the four rules from the second to the fifth.
The first rule was excluded because the abbreviated items could not be determined even if only this was followed, but it may be used together with other rules.

[2-2] Method of determining omitted items 2
In the embodiment, the abbreviation item determination unit 103 determines as abbreviated items a number of items exceeding the threshold Th1 used in the first rule, so that the larger the number of items in the list display data, the more items are omitted. Determined as an item (second rule). This meant that as the number of items in the list display data increased, the number of omitted items always increased, but this is not limited to this.

The abbreviation item determination unit 103 may increase the number of abbreviated items by one each time the number of items in the list display data increases by two, for example. With this method, the number of omitted items may not change even if the number of items in the list display data increases by one, but the number of items displayed as an index is larger than when all items are displayed. It will be less and it will be easier for the user to understand the displayed items.

Furthermore, the abbreviated item determination unit 103 sets more items as abbreviated items when there are N items (M and N are natural numbers in the relationship of M <N) than when there are M items in the list display data. Anything that can be decided will do. By determining the omitted items in this way, even if the number of items increases from M to N, it is omitted compared to the case where any item is displayed as an index regardless of the number of items in the list display data. Since the number of items to be displayed increases, the number of items displayed as an index is suppressed, and the displayed items can be easily grasped.

[2-3] Considering the order of items In the embodiment, the omitted item determination unit 103 determines as many items as omitted items as the order of the list display data is farther from the currently displayed data item. (Fifth rule), not limited to this, as the order is closer, more items may be determined as omitted items.

FIG. 11 shows an example of the index displayed in this modification. In the example of FIG. 11, the touch screen 16 has an address and a group whose first characters are "R", "S", "T", "W", and "Z" included in the address list B4 shown in FIG. Among the items of the alphabet of G3, the index D5 including the items "A", "D", "E", "F", "H", "I", "K", "M", "N" is It is displayed.

In this example, the abbreviation item determination unit 103 determines the items after "O" among the alphabetical items of the group G3 in which the items of the list display data currently displayed are classified as the abbreviated items. .. In addition, the abbreviated item determination unit 103 also follows the second rule, and the item whose list display data does not have data classified into its own item (in this example, "B", "C", "G", "J"". , "L") is also determined as an abbreviated item.

In the example of FIG. 11, the index display control unit 104 displays the character string "YZ #" indicating that the item on the tail side of the alphabet is omitted instead of the omitted alphabet item. By displaying the index D5 in which the items are omitted in this way, the items classified into the same group as the items of the list display data currently displayed and the order is farther from the items are easier for the user to grasp.

In the example of FIG. 11, only the order of items common to the groups is considered, but the order of items of different groups may also be considered. For example, in the above-mentioned groups G1, G2, and G3, the order is determined such that G1 is the first, G2 is the second, and G3 is the third.
FIG. 12 shows another example of the index displayed in this modification. In the example of FIG. 12, the touch screen 16 displays the address list B4 represented by FIG. 11 and the index D6 including the hiragana items from “a” to “wa” in the group G1.

In this example, the abbreviated item determination unit 103 is an item in the order closest to the currently displayed list display data item (alphabet "R", "S", "T", "W", "Z"). The alphabetical items of a certain group G3 and the numerical items of the group G2 are determined as abbreviated items. By displaying this index D6, it becomes easier for the user to grasp the items (items of group G1 in this example) that are farther from the items of the list display data currently displayed.

[2-4] Considering the number of data of each item The number of data divided into each item may be considered in determining the omitted item. In this case, the abbreviated item determination unit 103 determines the abbreviated item based on the number of list display data classified into each item. The abbreviated item determination unit 103 determines, for example, an item in which the number of list display data classified into its own item is less than the threshold value Th21 as an abbreviated item.

FIG. 13 shows an example of the index displayed in this modification. In the example of FIG. 13, the touch screen 16 shows an address having "te", "to", "na", "no", "ha", and "hi" included in the address list B7 as the first character, and "hi". Index D7 that includes items such as "a", "ka", "sa", "ta", "ha", "ma", "A", "D", "E", "H", and "T" It is displayed. All the items included in the index D7 are the items whose number of list display data classified into their own items is the threshold Th21 or more, and all the items not included in the index D7 are the list display classified into their own items. This is an item in which the number of data is less than the threshold value Th21.

For example, the address list B7 includes addresses whose first characters are "na" and "no", but since there are only two list display data classified into "na", the threshold Th21 is 3 or more. If so, the abbreviated item determination unit 103 determines the item "na" as an abbreviated item. In the example of FIG. 13, the number of displayed items fits in the display column H1 of the index, but the number of items is increased and the number of list display data classified into own items is any of the items having the threshold value Th21 or more. If it is necessary to omit, the above-mentioned order may be taken into consideration, or the group may be taken into consideration.

By displaying the index D7 in which the items are omitted in this way, it is easier for the user to grasp the items having a larger number of divided list display data. Contrary to the above example, the abbreviated item determination unit 103 may determine an item in which the number of list display data classified into its own item is the threshold value Th22 or more as an abbreviated item. In this case, the smaller the number of divided list display data, the easier it is for the user to grasp. In either case, the items that are easy for the user to understand change according to the number of classified list display data.

[2-5] Display area of each item In the embodiment, the index display control unit 104 displays each item side by side at a common interval, but the present invention is not limited to this. The index display control unit 104 may display the item in an area having a size corresponding to the number of data classified into the own item in the list display data, for example.

FIG. 14 shows an example of the index displayed in this modification. In the example of FIG. 14, the touch screen 16 has "a", "i", "", "su", "se", "so", and "ta" included in the address list B8 as the first characters. The address and the index D8 including the items "a", "sa", "ta", "ha", and "ma" are displayed. The index display control unit 104 has the height L1 of the display area J1 of the item "A" in which the two addresses are divided, and the height L2 of the display area J2 of the item "Sa" in which the four addresses are divided. Each item is displayed in half. The height here is the vertical dimension of the character.

The index display control unit 104 also displays other items in an area having a size corresponding to the number of data classified into each item. For example, "ta" is divided into only one address, and is displayed in the display area J3, which is half the height of the height L1 of the display area J1 of "a", and is displayed in the display area J3. "" Will be divided into three addresses, BR> 烽 Q, and are displayed in the display areas J4 and J5 of the height L1 common to the display area J1 of "A", respectively. By displaying each item in this way, it becomes easier for the user to grasp the number of list display data divided into each item, as compared with the case where each item is always displayed at a common interval.

[2-6] Display without considering the presence or absence of data If the omitted item is determined without following the third rule described in the example, the data classified into the own item is not included in the list display data (this is displayed). The first item) may also be displayed. At that time, when the operation of selecting the first item is performed, the item selection operation receiving unit 105 shown in FIG. This may be accepted as an operation of selecting the second item closest to the selected first item among the second items). When the operation for selecting the second item is received by the item selection operation reception unit 105, the item correspondence processing unit 106 performs processing according to the second item.

FIG. 15 shows an example of the index displayed in this modification. In the example of FIG. 15, on the touch screen 16, an address having "a", "i", "e", "o", "ra", and "ri" included in the address list B9 as the first character and "ri" are displayed. The index D9 including the items represented by the hiragana in each column from "a" to "wa" is displayed. Of these, the item K1 representing "a" and the item K3 representing "ra" are items in which the data classified into their own items are in the list display data, and the item K2 from "ka" to "ya" is any of them. Is also an item for which the data classified into its own item is not included in the list display data.

FIG. 16 shows an example of how an item is selected. In the example of FIG. 16, it is shown that the user's finger E1 is performing an operation of selecting the item “ha” in the index D9. In the item selection operation reception unit 105, since the item "ha" corresponds to the above-mentioned first item (item in which the data classified into the own item is not in the list display data), the second item closest to "ha" (own item). The data classified into is accepted as an operation to select "ra" which is an item) in the list display data.

The item selection operation receiving unit 105 determines, for example, that the second item having the smallest number of other first items sandwiched between the selected first item and the second item is the closest second item. In the example of FIG. 16, four first items, "ka", "sa", "ta", and "na", are sandwiched between the selected "ha" and the second item "a", and are selected. Since the two first items, "ma" and "ya", are sandwiched between the "ha" and the second item "ra", the item selection operation reception unit 105 is the second closest to the "ra". I judge it to be an item.

Not limited to this method, the item selection operation reception unit 105 calculates, for example, the coordinates of the center point of the area of the touch screen 16 in which the finger E1 is in contact, and the characters of the second item from the coordinates are calculated. The second item in which the shortest distance is calculated by calculating the distance may be determined as the second item closest to the selected first item. In the example of FIG. 16, the item correspondence processing unit 106 displays the enlarged image F9 representing the second item “ra” for which the selection has been accepted, and the “ra” among the addresses included in the address list B9. The process of instructing the list display control unit 101 to display the addresses classified into the above is being performed.

In this modification, when the operation of selecting the first item for which there is no data to be displayed in the list is performed, the data of the second item is displayed as a list. That is, since the area for selecting the second item extends to the area where the adjacent first item is displayed, it is displayed in the list as compared with the case where the operation for selecting the first item is accepted as it is. It becomes easier to select the second item that has the data to be used.

[2-7] Items The items in which data is divided are not limited to those described in the examples (items corresponding to the first sound (speech sound)). For example, the first sound itself may be an item. In this case, the Japanese syllabary is displayed as an item such as "a", "i", "u", "e", "o", "ka", ... "wa". Further, the addresses described in the cities, wards, towns and villages may be classified by the attributes of the data, for example, by the prefecture to which those addresses belong. In short, it suffices if the data is divided according to some rule.

[2-8] Group of items The group in which items are classified is not limited to those described in the examples (hiragana, numbers, alphabets). For example, katakana, kanji, or Arabic characters may be used. When the data is divided by the prefectures mentioned above, the groups may be classified by region such as Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chugoku, Shikoku, Kyushu, and Okinawa. In short, the groups need only be classified based on some commonality.

[2-9] Omission method In the embodiment, "12 #" and "AZ #" are displayed as characters indicating that they are omitted, but the item is not limited to this, and the item is, for example, the character "...". It may be expressed that it is omitted. In either case, it is desirable to use characters that intuitively recognize that the item is omitted. It should be noted that the abbreviation may be expressed by a figure or the like instead of a character.

[2-10] Display means In the embodiment, one device (display device 10) includes a display control unit (list display control unit 101, index display control unit 104) and a display means (touch screen 16). Separate devices may include a display control unit and display means. For example, a display as a display means may be connected to an information processing apparatus including a display control unit, and the display control unit may control the display to display a list and an index. Also, the display does not have to be a touch screen. In that case, the data list may be scrolled or items may be selected using the mouse or keyboard.
