A list button 408 is a button for displaying a list screen, which will be described later, in which a list of messages belonging to one category is displayed in a fixed size regardless of the number of characters included in the message. A list button 408 is an example of an operator for displaying a list.

In FIG. 4, the category image 401 is an image showing the category of the message displayed in the message display area 406. FIG. In the case of FIG. 4, "sightseeing/event" is displayed as a category. Also, the category image 401 is displayed at a predetermined position (approximately in the center in the horizontal direction) as shown in FIG. The category images 401 are movable in a predetermined direction (horizontal direction (either leftward or rightward direction). Therefore, the category images 401 are arranged virtually horizontally. Also, the predetermined direction may not necessarily be the horizontal direction, it may be the vertical direction, or it may be any other direction. For example, it may be a horizontal continuous movement or a horizontal discontinuous jump movement.

When an operation for moving the category image 401 is accepted by the user touching the move buttons 403 and 404, the display control unit 311 moves the category image in a predetermined direction and indicates a different category. Display the category image at a predetermined position. Then, the display control unit 311 updates the displayed message to a message belonging to the category indicated by the category image displayed at the predetermined position.

Specifically, the left adjacent category image 401L is a category displayed at a predetermined position when an operation (user touches the move button 404) is performed to move the category image currently displayed at the predetermined position in the right direction. Show the image. When the move button 404 is touched by the user, the message is updated to belong to the category indicated by the left adjacent category image 401L.

Badges 402 indicate the number of messages that can be displayed in message display area 406 . In the case of FIG. 4, there are three messages that can be displayed. Position image 405 indicates the horizontal position of the displayed category. The position image 405 is indicated by large dots (referred to as “large dots”) and small dots (referred to as “small dots”). The number of points included in position image 405 is the number of categories that can be displayed. FIG. 5 is a diagram for explaining the position image 405. As shown in FIG. FIG. 5 shows an enlarged position image.

Since the number of points included in the position image shown in FIG. 5 is seven, the number of categories that can be displayed is seven. Also, the large dot indicates the horizontal position of the currently displayed category. In FIG. 5, the large dot is the fourth from the left or the fourth from the right, so the horizontal position of the currently displayed category is the fourth from the left or the fourth from the right. Furthermore, both large dots and small dots are displayed as either black or white circles. A black circle indicates that there is no message that can be displayed in message display area 406 . A white circle indicates that there is one or more messages that can be displayed in message display area 406 . Although black circles and white circles are used in this way, since the position image 405 in FIG. 4 is small, only black circles are represented in FIG. 4 for convenience.

The size of the circle allows the user to confirm at a glance the horizontal position of the currently displayed category. Furthermore, the user can confirm at a glance whether there is a message or not, depending on whether it is a black circle or a white circle. In the present embodiment, the size and color of the circle are used as a form for distinguishing the position and the presence or absence of the message, but the present invention is not limited to this, and any form can be used as long as the form can be distinguished. There may be.

Returning to FIG. 4, the message display area 406 is provided with a next button 411 and a detail button 412 that can accept predetermined operations. A next button 411 is a button for displaying the next message when there is a next message to be displayed next. The next button 411 is displayed even when there is no message to be displayed next. A detail button 412 is a button for displaying the details of the message. When the Next button 411 is touched or the Details button 412 is touched, the currently displayed message is hidden.

A detail button 412 is a button for displaying a detail screen showing more detailed content than the message displayed in the message display area 406 . The message area 406 shown in FIG. 4 has a constant size regardless of the number of characters in the message. Therefore, all messages with less than a predetermined number of characters can be displayed, but all messages with more than a predetermined number of characters cannot be displayed.

Therefore, in the present embodiment, a detailed screen including all messages can be displayed. FIG. 6 is a diagram showing an example of a detailed screen. Although no image or link is displayed in the message display area 406, as shown in the detail screen 420, the detail screen can also display an image 422 and a link 423. FIG. An X button 421 provided on the right side of the detail screen is a button for closing the detail screen. When the X button 421 is touched by the user, the home screen shown in FIG. 4 is displayed.

Next, the Next button 411 shown in FIG. 4 will be described. When the next button 411 is touched on the home screen 400 shown in FIG. 4, the next message is displayed. FIG. 7 is a diagram showing an example of the home screen 430 displaying the next message. As shown on home screen 430 , badge 402 shows “2”, which is one less than “3” displayed on home screen 430 . Furthermore, in the message display area 406, the number of messages is reduced by one from three, and the two message display areas 406 are displayed so as to overlap each other.

Since the size of the message display area 406 on the home screen is fixed regardless of the number of characters, the larger the number of characters in one message, the larger the display area in the screen. This reduces the possibility that the user will miss important information. Furthermore, even if there is a message with a large number of characters, it is displayed in a fixed size, so that one message does not occupy the display area. can be done. Also, it is possible to confirm at a glance whether or not there is another message by overlapping the message display area 406 and the badge 402 .

Also, the user can know the details of the message of interest by pressing the detail button 412 on the home screen. On the other hand, the next button 411 can be used to display the next message for the message that the user is not particularly interested in.

If the next button 411 is continuously touched on the home screen 400, eventually there will be no more messages to display. FIG. 8 is a diagram showing an example of the no-message home screen 440 when there are no more messages to display. On the no-message home screen 440, a character string 441 indicating that there are no more messages to be displayed (all notices have been checked. If you want to read them again, tap "View list") and a list button 442. is displayed. A list button 442 has the same function as the list button 408 . That is, when the list button 442 is touched, the list screen is displayed.

FIG. 9 is a diagram showing an example of the list screen. On the list screen 500, category tabs 501, display selection radio buttons 502, subject display area 503, and read/unread display 504 are displayed. A category tab 501 is a tab for the user to select a category. The selected tab is displayed approximately in the center in the horizontal direction. Subjects of messages belonging to the category corresponding to the selected tab are displayed in list view.

A display selection radio button 502 is a radio button for selecting a subject to be displayed in the subject display area 503 . "All" in the display selection radio button 502 is a button for displaying the subjects of all messages, not just unread and read messages. "Read only" is a button for displaying the titles of messages that have already been read. "Unread only" is a button for displaying the subject of unread messages.

In the subject name display area 503, update date and read/unread display 504 are displayed in addition to the subject name. The read/unread display 504 displays "read" when the details of the message with this subject are displayed, and "unread" when the details of the message are not displayed. When the user touches one of the displayed subject name display areas 503, a detailed screen corresponding to the touched subject name display area 503 is displayed.

As shown in FIG. 9, the display control unit 311 can display a list of messages belonging to one category in a list display that displays the list in a fixed size regardless of the number of characters included in the messages. By doing so, the display area in the screen does not increase as the number of characters in one message increases, so that the user naturally pays attention to the content of the message, so that the user may miss important information. can reduce the probability. Furthermore, even if there is a message with a large number of characters, it is displayed in a fixed size, so that one message does not occupy the display area. can be done.

In the above-described embodiment, the categories to be displayed may be appropriately selectable by the user. Also, a category that is always displayed to all users may be provided. That is, categories that can be selected by the user and categories that must be displayed to all users may be provided. FIG. 10 is a diagram showing an example of a selection screen for categories to be displayed. This selection screen 600 also shows "Important Notice" as a category that must be displayed to all users. As shown in FIG. 10, a check box 601 is provided for each category other than "Important Notice". Information indicating the category selected by the user on the selection screen 600 is stored in the storage unit 330 . The display control unit 311 controls to display messages belonging to the category selected by the user from among the categories of the message information 331 . By providing a category that must be displayed to all users, the distribution device 100 can easily distribute messages that are desired to be displayed to all users. In addition, since the user can also recognize that the category that must be displayed to all users is a special category, it is possible to prevent messages from being overlooked.

Next, the flow of processing will be described using a flowchart. 11 and 12 are flowcharts showing the processing flow of the user terminal 300. FIG. In FIG. 11, prior to displaying the home screen 400, the user terminal 300 acquires new message information that has not yet been acquired from the distribution device 100, and displays the home screen (step S101). The acquired message information is stored in the storage unit 330 described above. Note that the category image displayed on the home screen may be the one displayed last time, or may be determined by default. Also, the message information may be acquired by a push notification by the distribution device 100 .

The operation accepting unit 312 determines whether or not an operation for moving the category image in a predetermined direction has been accepted (step S102). When an operation for moving the category image in the predetermined direction is accepted (step S102: YES), the display control unit 311 moves the category image in the predetermined direction (step S103). Next, the display control unit 311 displays, at a predetermined position, a category image indicating a category different from the category of the category image displayed before accepting the operation (step S104). Display control unit 311 updates the message displayed in message display area 406 to a message belonging to the category indicated by the category image displayed at the predetermined position (step S105), and returns to step S102.

In step S102 above, if an operation for moving the category image in the predetermined direction has not been accepted (step S102: NO), the operation accepting unit 312 determines whether or not a touch on the details button 412 has been accepted. (Step S106). If the detail button 412 has been touched (step S106: YES), the display control unit 311 displays the detail screen (step S107). When the operation accepting unit 312 accepts the touch on the X button 421 (step S108: YES), the display control unit 311 displays the original message (step S109), and returns to step S102.

If the detail button 412 has not been touched in step S106 (step S106: NO), the operation accepting unit 312 determines whether or not the next button 411 has been touched (step S110). When the next button 411 is touched (step S110: NO), the display control unit 311 determines whether or not there is a next message (step S111). If there is a next message (step S111: YES), the display control unit 311 displays the next message (step S112) and returns to step S102. If there is no next message (step S111: NO), the display control unit 311 displays the no-message home screen 440 (step S113), and returns to step S102.

If the next button 411 has not been touched in step S110 (step S110: NO), the operation accepting unit 312 determines whether or not the list button 408 has been touched (step S114). If the touch on the list button 408 has not been accepted (step S114: NO), the process returns to step S102. If the touch on list button 408 is accepted (step S114: YES), the process proceeds to step S201 in FIG.

In FIG. 12, the display control unit 311 displays the list screen 500 (step S201). The operation accepting unit 312 determines whether or not a touch on the category tab 501 has been accepted (step S202). If the category tab 501 has been touched (step S202: YES), the display control unit 311 displays a list screen of messages belonging to the touched category (step S203), and returns to step S202.

If the category tab 501 has not been touched in step S202 (step S202: NO), the operation reception unit 312 determines whether or not selection of the display selection radio button 502 to "all" has been received. (step S204). When the selection of "all" of the display selection radio button 502 is accepted (step S204: YES), the display control unit 311 displays a list screen of the subjects of all messages (step S205), and proceeds to step S202. return.

In step S204 above, if the selection of the display selection radio button 502 to "all" has not been accepted (step S204: NO), the operation reception unit 312 determines that the selection of the display selection radio button 502 to "already read" has not been accepted. It is determined whether or not it has been accepted (step S206). If the selection of "already read" of the display selection radio button 502 is accepted (step S206: YES), the display control unit 311 displays a list screen of the subject of the message that has already been read (step S207). Return to S202. Whether or not the message has been read can be determined by referring to the read flag.

In step S206, if the selection of the display selection radio button 502 to "read" has not been accepted (step S206: NO), the operation reception unit 312 determines that the selection of the display selection radio button 502 to "unread" has not been accepted. It is determined whether or not it has been accepted (step S208). If the selection of "unread" from the display selection radio button 502 has been accepted (step S208: YES), the display control unit 311 displays a list screen of the subjects of unread messages (step S209), and proceeds to step S202. return. Whether or not the message is unread can be determined by referring to the read flag.

In step S208, if the selection of the display selection radio button 502 to "unread" has not been accepted (step S208: NO), the operation accepting unit 312 determines whether or not the home button 407 has been touched. (step S210). If the home button 407 has been touched (step S210: YES), the display control unit 311 displays the home screen (step S221), and returns to step S102 in FIG. If the home button 407 has not been touched (step S210: NO), the process returns to step S202.

As described above, according to the present embodiment, when an operation for moving a category image in a predetermined direction is accepted, the display control unit 311 moves the category image in the predetermined direction and displays a different category. Since the category image is displayed at a predetermined position, the user's operability can be improved. In addition, since the displayed message is updated to a message belonging to the category shown in the category image displayed at the predetermined position, visibility for the user can be improved.

Further, in the present embodiment, when an operation for displaying details of a message or an operation for displaying a message to be displayed next is accepted, the display control unit 311 displays the message display area where the operation was accepted. The displayed message is hidden, and the content corresponding to a predetermined operation is displayed. By doing so, it is possible to display the details of the message and display the next message with one operation, so that the operability for the user can be improved.

In addition, since the message display area has a constant size regardless of the number of characters included in the message, it is possible to improve visibility for the user compared to the case where the size varies. Furthermore, the display control unit 311 can display a list of messages belonging to one category in a list display that displays the list in a fixed size regardless of the number of characters included in the message. By comparison, the user's visibility can be improved.
