Summary of the Invention
Problem to be Solved by the Invention
[0004] Incidentally, when holding an event, as disclosed in Patent Document 1, it is considered that processing of participation fee payment becomes complicated. In addition, there are many other complicated operations such as creation of documents using participant information and provision of various types of information to participants.
[0005] For example, taking a wedding reception as an example, it was necessary to create a seating chart that included the names, titles, and relationships of the guests to the bride and groom. In addition, it was sometimes necessary to introduce the guests' profiles and messages, and creating seating charts, profile collections, and message collections required a great deal of effort. Furthermore, these seating charts, profile collections, and message collections had to be distributed to the guests on the day of the reception, and this distribution process was also complicated. In addition, providing various kinds of information to guests, such as menus for the meals served at the wedding reception and the program of the ceremony, also required the preparation and distribution of these items, which was also a complicated process.
[0006] This disclosure is made in light of the above points, and its purpose is to make it easier to create documents using participant information and to provide various types of information to participants. [Means for solving the problem]
[0007] To achieve the above objective, this disclosure may be based on a participant registration device configured to be communicatively connected to participant terminals owned by multiple participants participating in an event, to receive participant information transmitted from the participant terminals, and to transmit event-related information to the participant terminals.
[0008] The participant registration device displays an input form on the display unit of the participant terminal that allows the participant to input participant information, including at least the participant's name, email address, and telephone number. It generates name display screen data as event-related information that displays the participant's name included in the participant information entered in the input form according to a predetermined rule. It transmits URL information relating to a URL that allows access to the event-related information to at least one of the participant's email address and telephone number included in the participant information. It transmits the event-related information to the participant terminal accessed from the URL, causing the display unit of the participant terminal to display a screen based on the name display screen data.
[0009] In other words, when an event participant enters participant information, including their name, email address, and phone number, into the input form displayed on the participant terminal, the entered participant information is transmitted from the participant terminal to the participant registration device. The participant registration device, upon receiving the participant information, generates name display screen data as event-related information, displaying the participant's name according to a predetermined rule. For example, the participant registration device can generate name display screen data that groups multiple participants together, or name display screen data that arranges participants in a certain order. Meanwhile, URL information that allows access to the event-related information is sent to at least one of the email address and phone number, so participants can view the event-related information by accessing that URL.
[0010] Furthermore, the participant registration device may be configured to accept registration processing by participants after the participant information has been transmitted but before they participate in the event. In this case, after accepting the registration processing, the URL information can be sent to at least one of the participant's email address and telephone number included in the participant information. For example, event-related information can be kept secret from participants until they complete the registration process on the day of the event. Then, on the day of the event, participants can only learn about the event-related information after completing the registration process.
[0011] Furthermore, the participant registration device may generate schedule display screen data that displays the event schedule as event-related information. In this case, the event-related information can be transmitted to the participant terminal accessed via the URL, causing the participant terminal's display unit to display a screen based on the schedule display screen data. This allows information regarding the event schedule to be provided to each participant.
[0012] Furthermore, the participant registration device may display an input form on the display unit of the participant terminal that allows the participant to input a photograph. In this case, the name display screen data, which displays the participant's photograph entered in the input form in association with the participant's name, can be generated as event-related information and displayed on the display unit of the participant terminal accessed via the URL, showing the participant's photograph and their name in association.
[0013] Furthermore, the participant registration device may generate image information, including multiple event images taken of the event, as event-related information. In this case, after the event ends, the multiple event images can be displayed on the display unit of the participant terminal accessed via the URL. Thus, the participant registration device can be used not only during the event but also after the event has ended. [Effects of the Invention]
[0014] As explained above, the participant registration device automatically generates display screen data that shows the names entered by participants according to predetermined rules, and can provide the generated display screen data to participants. This makes it easy to create documents using participant information and to provide participants with various kinds of information. [Brief explanation of the drawing]

[0026] The communication module 104 is for transmitting various information stored in the memory unit 105, various information entered by participants, data generated by the control unit 101, etc., to the organizer terminal 2. The communication module 104 can also receive various information transmitted from the organizer terminal 2 and input it to the control unit 101. The network N to which the communication module 104 is connected is not limited to the internet, but may be a local area network (LAN) set up within the venue where the event is held. Furthermore, the communication module 104 may be connected to the network N by wire or by wireless connection, and its communication method is not particularly limited.
[0027] (Details of the operation of the participant registration device) Figure 4 is a flowchart illustrating an example of the information transmission and reception procedure implemented by the participant registration device 1. In this embodiment, the case where the event is a wedding reception will be described. Before executing the process in this flowchart, a preparation step is performed. In the preparation step, a list of guests to be invited to the wedding reception is compiled, and arrangements are made for the venue, the meals on the day, and the prizes to be distributed in the games described later. The invited guests are those who may become participants, and can also be called potential participants.
[0028] In Step SA1, for example, the organizer sends invitations to participants. Only those who receive an invitation, i.e., the invitees, can attend the wedding reception, thus limiting who can participate. The invitations can be sent to participants by email or in paper form. It is also possible to recruit or invite participants using online community services such as SNS (Social Networking Services), and there are no particular limitations on the method of recruiting and inviting participants.
[0029] In step SA2, the invited person enters their response. The invited person accesses the response webpage identified by the URL provided in the invitation. The control unit 10 of the organizer terminal 2 then sends an input form that allows participant information to be entered to the participant terminal 100, and displays it on the display 102 of the participant terminal 100 via the display control unit 101a. The input form is configured to allow the entry of participant information, including at least the participant's name, email address, and telephone number.
[0030] Specifically, the control unit 10 generates an input form image 200 as shown in Figure 5 and displays it on the display 102 via the display control unit 101a. The input form image 200 includes an input area 201 for confirming participation status, a name input area 202 for entering the participant's name, a phone number input area 203 for entering the participant's phone number (mobile phone number), an email address input area 204 for entering the participant's email address, an address input area 205 for entering the participant's address, a relationship input area 206 for entering the relationship between the participant and the bride or groom, a title input area 207 for entering the participant's title, an allergy information input area 208 for entering the participant's allergy information, and a photo input area 209 for entering the participant's photo. Name, address, relationship, title, allergy information, and photo are also included in the participant information. Participation status information, phone number, email address, address, relationship, title, allergy information, and photo are stored in association with identification information. Identification information may be information unique to the participant, such as a phone number or email address.
[0031] Please note that you do not need to fill in all of the participant information mentioned above; you may fill in only the items you wish to. Furthermore, participant information is not limited to what is listed above; it may also include, for example, age and occupation. Participant information may also include messages addressed to the bride and groom, and personal profiles. In this case, messages and profiles will also be stored in association with the identification information. Messages and profiles can also be entered through the input form.
[0032] In the input area 201 for participation status, participants can select "Yes" or "No". In the name input area 202, participants can enter their full name and phonetic spelling. In the relationship input area 206, participants can enter information such as relative, friend, or colleague. In the title input area 207, participants can enter information such as their title at the company where they work. In the allergy information input area 208, participants can enter information about foods that trigger allergic reactions. The organizer can then prepare a menu that takes allergies into consideration for participants who have entered allergy information. In the photo input area 209, participants can input images they have taken of themselves.
[0033] Once the participant has completed entering information into each input field 201-209 of the input form image 200, they operate the upload button 210 included in the input form image 200. When the upload button 210 is operated, the participant information entered into each input field 201-209 is sent from the participant terminal 100 to the organizer terminal 2. The participant information sent to the organizer terminal 2 is received by the organizer terminal 2 and then stored, for example, on a server 6.
[0034] In step SA4, the control unit 10 generates event-related information. Specifically, the control unit 10 generates name display screen data as event-related information, which displays the names of participants included in the participant information entered in the input form according to predetermined rules. For example, as shown in Figure 6, the control unit 10 generates screen data for displaying the seating chart image 300. The seating chart image 300 is displayed on the display 102 of the participant terminal 100, as will be described later.
[0035] The seating chart image 300 includes a floor plan display area 301 that shows a floor plan of the venue, and a name display area 302 that shows the names of the participants seated at each table. Displaying according to the prescribed rules means that, as in the case of creating a seating chart, when multiple tables are set up in one venue, the participants are assigned to each table so that the number of people at each table is equal. In addition to displaying participants assigned to each table, displaying according to the prescribed rules may also include, for example, displaying them in alphabetical order, or in order of closeness of relationship to the bride and groom, etc.
[0036] Furthermore, the event-related information generated by the control unit 10 may include, in addition to the name display screen data, a schedule display screen 400 that displays the event schedule, as shown in Figure 7. The schedule display screen 400 shows the schedule and flow for the day of the event, and is displayed chronologically with, for example, times and scheduled items associated with each other. The schedule display screen 400 is generated by the control unit 10 based on the schedule entered in the preparation process, for example.
[0037] In step SA5, the control unit 10 of the organizer terminal 2 accepts the participant's registration process after the participant has sent their participant information but before the participant attends the wedding reception. For example, if the participant performs a predetermined registration operation on the participant terminal 100 on the day of the wedding reception but before the reception is held, the registration operation is accepted by the control unit 10. Alternatively, after the participant information is uploaded in step SA3, a QR code may be sent to the participant via email or other means, and on the day of the wedding reception but before the reception is held, the participant scans the QR code with a scanning device (not shown) at the reception. The control unit 10 performs an authentication process on the scanned QR code, and if the authentication process confirms that the participant is a legitimate participant, the control unit 10 accepts it as registration by the participant.
[0038] After the control unit 10 receives the reception processing, the process proceeds to step SA6. In step SA6, URL information relating to a URL that can access event-related information is sent to at least one of the participant's email address and telephone number included in the participant information. The URL information may be the URL itself, or it may be a link consisting of characters or symbols that can identify the URL.
[0039] Participants perform an operation to access a URL identified by URL information sent to the participant terminal 100. This operation is transmitted to the control unit 10. When the control unit 10 detects that an operation to access a URL has been performed, it generates data to display the entrance screen 500, as shown in Figure 8, and displays it on the display 102 of the participant terminal 100 via the display control unit 101a. The entrance screen 500 is provided with a participant name display area 501 that displays the name of the participant who accessed it, and a participant photo display area 502 that displays a photo of the participant who accessed it. In other words, the URL is designed to identify who the participant who accessed it is, and as a result, the control unit 10 identifies the participant who accessed it and generates the entrance screen 500 by incorporating the information corresponding to the participant name display area 501 and the participant photo display area 502, respectively.
[0040] The entrance screen 500 is equipped with a seating chart button 503, a schedule confirmation button 504, a menu confirmation button 505, a game button 506, a gift confirmation button 507, a prize confirmation button 508, and a retrospective album button 509. When the control unit 10 detects that the seating chart button 503 has been operated, in step SA7 it transmits screen data to the participant terminal 100 to display the seating chart image 300 shown in Figure 6. In step SA8, the control unit 10 displays the seating chart image 300 on the participant terminal 100's display 102 via the display control unit 101a.
[0041] In the seating chart image 300 shown in Figure 6, the circles displayed in the floor plan display area 301 represent the tables set up in the venue. When a participant selects a table (circle) on the floor plan display area 301, the names of the participants seated at that table are displayed in the name display area 302. In addition, the name display area 302 displays the participant's photo and their name in association with each other. This allows all participants to know who is seated at which table.
[0042] When a participant selects a name displayed in the name display area 302 of the seating chart image 300, the selected name, associated photo, title, and relationship are displayed in a separate window. In other words, the control unit 10 generates name display screen data as event-related information, which displays the participant's photo entered in the input form in association with the participant's name, and can display the participant's photo and name in association on the display 102 of the participant terminal 100 accessed via URL. If a message or profile has been entered, the message and profile will also be displayed in the separate window.
[0043] When the control unit 10 detects that the schedule confirmation button 504 has been operated, it displays the schedule display screen 400 shown in Figure 7 on the participant terminal 100's display 102 via the display control unit 101a, based on the schedule display screen data. This allows the participant to see today's schedule.
[0044] When the control unit 10 detects that the menu confirmation button 505 has been pressed, it displays the menu for the wedding reception on the display 102 of the participant terminal 100. This allows participants to know what the menu for the day will be. For participants who have entered allergy information in advance, the menu will be adjusted to accommodate their allergies, and the allergy-friendly menu will be displayed.
[0045] When the control unit 10 detects that the game button 506 has been pressed, it displays a screen on the participant terminal 100's display 102 that allows for various games. The type of game is not particularly limited, but examples of games that can be played with the bride and groom and other participants include games in which prizes can be won, such as bingo. If a prize is won, information about the prize win is stored and associated with the participant.
[0046] When the control unit 10 detects that the gift confirmation button 507 has been pressed, it displays the gift on the display 102 of the participant terminal 100. This allows participants to know what their gift will be in advance. Information about the gift only needs to be entered during the preparation process, and this information can be provided to participants as event-related information.
[0047] When the control unit 10 detects that the prize confirmation button 508 has been operated, it displays the prizes that can be won in the game on the display 102 of the participant terminal 100. Information about the prizes only needs to be entered in the preparation process, and the information about the prizes entered in the preparation process can be provided to the participants as event-related information. In addition, for participants who have won a prize, it is possible to accept the input of the shipping address for the prize after the wedding reception has ended. This ensures that the prizes are shipped quickly. The prize information acquired by the game winner is transferred to the participant terminal 100, and the participant terminal 100 can initiate the prize shipping process (after the address has been entered).
[0048] When the control unit 10 detects that the retrospective album button 509 has been operated, it displays the event images on the participant terminal 100's display 102. In other words, during the wedding reception, a photographer takes pictures of the reception and acquires multiple event images. The photographer may be a professional photographer or a participant. The acquired multiple event images are uploaded to the organizer terminal 2 for loading.
[0049] The control unit 10 generates image information containing multiple event images read by the organizer terminal 2 as event-related information. The control unit 10 can generate image information with multiple event images arranged in the order they were taken, or image information with only the images selected by the organizer. The organizer can also set the number of event images to be included in the image information. The retrospective album button 509 can be operated after the wedding reception has ended. When the retrospective album button 509 is operated after the wedding reception has ended, the control unit 10 displays multiple event images on the display 102 of the participant terminal 100. In this way, participants can use the event-related information provided by the participant registration device 1 even after the wedding reception has ended.
[0050] (Effects of the embodiment) As described above, according to this embodiment, when a participant enters participant information, such as their name, email address, and telephone number, into the input form displayed on the display 102 of the participant terminal 100, the entered participant information is transmitted from the participant terminal 100 to the organizer terminal 2 of the participant registration device 1. The control unit 10 of the organizer terminal 2, upon receiving the participant information, generates event-related information such as a seating chart using the participant's name. Meanwhile, URL information that allows access to the event-related information is sent to at least one of the email address and telephone number, so that the participant can view the event-related information by accessing it via that URL. In this way, display screen data that displays the name entered by the participant according to predetermined rules can be automatically generated and the generated display screen data can be provided to the participant, making it easy to create documents using participant information and provide various kinds of information to participants.
[0051] The embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. Furthermore, any modifications or changes that fall within the equivalent scope of the claims are all within the scope of the present invention.
[0052] For example, if someone assigned a role such as giving a toast, a speech, or entertainment will be viewing the event on their own mobile device, they may mark their role with a symbol, such as a checkmark.
[0053] Additionally, a feature could be added to organize photos by category, linking the time slots set in the schedule with the time slots when photos were taken on the mobile device. Furthermore, users could attach messages to their photos, and since the photos and names are linked, the system could automatically identify who posted the message.
[0054] Additionally, you could display the guest's table number on the entrance screen.
[0055] Additionally, you could add fields to the web invitation's response section for participants' hobbies, profiles, and self-promotional content. Possible uses include seating charts and bingo games. For seating charts used in business events, including participant profiles and self-promotional content allows attendees to see what each participant does for a living. For bingo games, you could display participants' photos, names, hobbies, and other information, serving as a form of self-introduction. [Industrial applicability]
[0056] As described above, the participant registration device according to the present invention can be used, for example, when holding events such as wedding receptions and wedding after-parties. [Explanation of symbols]
