Description

  The present invention enables a person who wants to send a business message using a computer and a plurality of users to be able to interact, and sends a business message from the business message sender of the exchange destination to the user who has become able to interact. The invention relates to a computer system and program for enabling.

  As a way to enable specific people to interact with each other by using a computer, for example, notify the other party of the e-mail address or telephone number of their mobile phone and contact them. It is a conventional method in general to make it possible to make it possible (hereinafter referred to as the "communicable state"). Then, there has been proposed a mobile phone capable of storing the e-mail address or the like of the other party in the address book of the mobile phone of the user and displaying a list according to the user's operation (for example, Patent Document 1).

Patent No. 4256374 gazette

However, in the case of this conventional and commonly available communication state, there are the following drawbacks.
a In many cases, it is likely that he / she feels uneasy about the point of informing the other party of the personal information such as the telephone number and the e-mail address, and this loses the opportunity for the later exchange.
b There is a risk that a person who has notified you of personal information may contact you at any time of the day or night and suffer from inconvenience.
c The personal information such as the e-mail address given to the other party may be leaked to another person, others may pretend to be the person, send e-mail, or suffer damage such as spam.
d In order to invalidate personal information that has been given, it involves troublesome tasks such as changing the phone number and changing the e-mail address.

  In view of the above, in the ideal communicable state, contact can be made later without notifying the other party of each other's personal information, and another person other than the other party will come into contact as the other party. It is a state that can also prevent inconvenience.

  The present invention has been made in view of such circumstances, and its object is to provide means for establishing the aforementioned ideal communicable state.

First Embodiment
First, the outline of the present invention will be described on the basis of FIGS. 1 and 2 in which an example of use of the present invention is illustrated.

[Summary of the Invention]
FIG. 1 shows an example of establishing a communicable state when people meet in the real world.

  Referring to FIG. 1, people in the first meeting meet in front of the International Japan Cultural Center (Yotsuya Kaidan Museum) in Yotsuya, and based on their agreement, they create a shared virtual tag using their mobile phones 2 did. This shared virtual tag is a tag that is created and displayed in the place of the virtual world corresponding to the place where both people meet, and can be accessed only by the mobile phones of both people who meet and write there. It was made to be able to contact.

  This virtual world is a digitally imaged metaverse that corresponds to the landscape of the real world. As mentioned above, for example, Google's street view is used. Alternatively, instead of using an existing one, it may be newly created by digital imaging imitating the landscape of the real world. FIG. 1 shows that the shared virtual tag was created at 14:03 on October 15, 2009.

  In this state, if you access this virtual world (Street View etc.) and access to the front of Yotsuya International Japan Cultural Center which created the shared virtual tag, the mobile of Mr. A and Mr. B who created the shared virtual tag Only the phone 2 can project this shared virtual tag.

  In FIG. 1, first, a shared virtual tag is clicked by Mr. A's mobile phone 2 (meaning selection operation or designation operation, and so on), and Mr. A is shown in FIG. 1 on October 17, 2009. I am writing. When Mr. A writes, a pop-up notification is issued to notify Mr. B's mobile phone 2 to that effect. Mr. B accesses the virtual world the next day, clicks on the shared virtual tag, and writes as shown in FIG.

  As described above, by establishing a communicable state using the shared virtual tag, Mr. A and Mr. B can communicate with each other without notifying each other personal information such as a telephone number and an e-mail address.

  In addition, since access by terminals other than the mobile phone 2 of the person who created the shared virtual tag can not be performed, it is possible to prevent another person from writing by impersonation using his own mobile phone.

  Communication using such a shared virtual tag makes it possible to exchange information safely while protecting each other's personal information (privacy) and preventing damage such as spam, etc. Support the construction of

  FIG. 2 shows an example of contacting a human in the real world from the virtual world to generate a shared virtual tag. In the case of the virtual world, of course, it is possible to instantaneously move to a desired place. There are various conceivable situations in which the virtual world contacts human beings in the real world utilizing such merits of the virtual world.

  For example, as a preview of a travel destination, the virtual world accesses the travel destination in advance, contacts local residents, and collects local live information. Others find out later that they left behind in the classroom of the school, and immediately access the place corresponding to that classroom in the virtual world, and from there contact with people in the classroom in the real world, and that leftover It may be possible to have it be put on hold temporarily, and to get in touch for later withdrawal. However, a particularly important situation is when an emergency such as a disaster occurs.

  Figure 2 shows an example of providing assistance from a virtual world rushing to a disaster-stricken area. Figure 2 shows Mr. D, who saw the news of the disaster, using his own mobile phone to access the disaster area in the virtual world. When the resident in the earthquake disaster area has the mobile phone 2 having the GPS function, the avatar C of the resident is displayed at the position of the virtual world corresponding to the current position specified by the GPS function or the like. The avatar C is composed of an agent having an independent conversational ability.

  Mr. D who accessed the virtual world corresponding to the earthquake disaster place talks with the avatar C displayed in the place, and proposes making a virtual tag. Avatar C which received this proposal notifies that to the mobile phone 2 of the corresponding person. Mr. C, who is the owner of the notified mobile phone, consents to it and notifies Avatar C of an instruction to that effect. Then, it informs Mr. D that Avatar C has agreed, and a shared virtual tag between Mr. C and Mr. D is created in that part of the virtual world. In that state, when Mr. C accesses the virtual world and clicks on the shared virtual tag, Mr. D and Mr. C can exchange information as shown in FIG. It will be possible to provide efficient relief.

  Note that by configuring the shared virtual tag with a voice virtual tag to be described later, the user can leave a message in the tag by voice from the mobile phone, which is effective as an emergency message input method.

[Detailed description]
Next, a first embodiment of the present invention will be described in detail.

FIG. 3 is a system diagram showing the entire configuration of the human connection support system of the present invention.
The cellular phone 2 receives GPS (Global Positioning System) information from the satellite 1 and radio waves from the base station 3 connected to the cellular phone network 4 and radio waves from the wireless LAN (Local Area Network) access point 7 The mobile phone 2 receives. The mobile phone 2 identifies the current position based on these radio waves. The mobile phone 2 is configured to be accessible to the server 10 of the service provider 8 via the base station 3, the mobile phone network 4, the gateway 5, and the Internet 6. The service provider 8 is a vendor that provides a service that supports human connections. The user who is the owner of the mobile phone 2 is affiliated with the service of the service provider 8, and a user ID is set at the time of the affiliation.

  The service provider 8 is provided with a server 10, a user database 11 storing data of affiliated users, and a virtual tag database 9 storing data of virtual tags.

  The virtual world provider 20 connected to the Internet 6 is a service provider that provides images of a virtual world (metabirds) obtained by digitizing 360-degree panoramic images of anywhere in the real world. A virtual world database 22 is connected to the server 21 of the virtual world provider 20. The virtual world database 22 stores virtual world 3D data obtained by digitizing 360-degree panoramic images in the real world. For example, Google Street View 3D data can be used.

  This virtual world 3D data uses Flash (Flash) developed as an animation creation tool (animation authoring tool), and can realize interactive expression by describing a script. This flash is a type that controls the characters and images that you want to move programmatically, and you can create an animation by placing a still image on the timeline, which is called an action script (Action Script) The script language enables complex interactions such as games. Thereby, as described later, the agent (avatar) can be displayed in the 3D virtual world, and the user corresponding to the user is moved to the same corresponding position in the virtual world as the user moves in the real world. be able to.

  Position data is associated and stored for each area corresponding to a real world address in this virtual world 3D data. For example, as shown in FIG. 3, the location data (Shibuya Ward 1-1-1) is associated with the location of virtual world 3D data corresponding to the address of Shibuya Ward 1-1- 1 as the location data. It is memorized. As a result, when the user inputs position data including an address and specifies an access position, a portion of virtual world 3D data corresponding to the specified position data is read and the user terminal (mobile phone 2 or the like) Is displayed on).

  FIG. 4 is a diagram for explaining data stored in the user database 11 of the service provider 8. An agent ID for specifying an agent (avatar) of each member user is stored in association with each user ID. Furthermore, GPS data specifying the current position is transmitted to the server 10 of the service provider 8 from the user who turns on the GPS function of the mobile phone 2. The server 10 converts the transmitted GPS data into coordinate data composed of latitude and longitude, and stores the coordinate data in the user database 11 in the storage area of the current position GPS data of the corresponding user ID. For example, in the case of the user ID of 13B9 PS in FIG. 4, the latitude is 35.669299 and the longitude is 139.713655 as the current position GPS data.

  Furthermore, the server 10 stores the position data obtained by converting the current position GPS data (latitude and longitude) into position data composed of an address or the like in the position data storage area of the user database 11.

  Returning to FIG. 3, in the virtual tag database 9, position data, virtual tag display data, virtual tag type, and virtual tag creation date and time are stored in association with the user ID. Position data is data for indicating a place where a virtual tag is generated. The virtual tag display data is data for displaying a virtual tag in the virtual world, and is composed of text data, image data, and the like.

  The virtual tag type is data indicating the type of virtual tag to be displayed, and includes a voice virtual tag, an advertisement virtual tag, a shared virtual tag, and the like. Among them, the shared virtual tag is the one described in FIG. 1 and FIG. In the detailed description of the present invention, in addition to the shared virtual tag, there is also a virtual tag independently generated by the user or one vendor. A voice virtual tag is a virtual tag that can speak a message. An advertisement virtual tag is a virtual tag for an advertisement created by an advertiser. Virtual tags other than shared virtual tags can be freely accessed by anyone other than the creator of the virtual tag.

  Also, for example, the shared virtual tag shown in FIG. 2 can be configured by a voice virtual tag. Then, Mr. C and Mr. D can input voices without keying in messages, which has the advantage of being able to perform prompt input in an emergency.

  The creation date is data indicating the date when the virtual tag was created. For example, when the user ID is 13B9 PS, it is 0902190921, which means 09:21, February 19, 2009.

  The server 10 of the service provider 8 uses a virtual view mashed up with a street view etc. as a 3D virtual world on the net with an exact copy of the real world. The server 10 identifies the current position of the member user in the real world with the mobile phone 2 of the member user, and causes the avatar (agent) of the member user to be displayed at the location of the virtual world corresponding to the current position. When another member user enters the virtual world and encounters an avatar (agent), the member user and avatar (agent) can talk. The conversation via avatars in the virtual world is a well-known and commonly used technique conventionally used in the 3D virtual world such as Second Life, and this well-known common technique is used. In addition, since avatars (agents) are agents having an independent ability and a certain level of conversation ability such as the aforementioned CLON, users in the real world can delegate conversations to their avatars to a certain extent, and the contents of conversations are mobile phones Talk with the other person by yourself only when you need it while watching at.

  FIG. 5 is a block diagram of the hardware configuration of the mobile phone 2. The mobile end phone 2 has a central processing unit (CPU) 31 for controlling the entire mobile phone 2 including line connection processing and data communication processing, and a ROM (Read Only Member) storing programs for executing various functions. 32. A camera input unit 34 comprising a CCD (Charge Coupled Device) image pickup element for photographing a surrounding scene, storing at least one still image data obtained by photographing with the camera input unit 34 RAM (Random Access Memory) 33 including a memory for the display, a display unit 35 for outputting an image such as a liquid crystal display panel, a wireless communication processing unit 36 for communicating via the Internet 6, and a user It comprises an input operation unit 37 for causing the CPU 31 to execute a desired function. The input operation unit 37 includes a touch pen, a jog dial, a keyboard, a micro switch, and the like. The interface 41 performs interface processing to the internal bus 40 of various circuits and devices.

  Furthermore, the mobile phone 2 has an audio output unit 38a, a voice input unit 38b, an EEPROM (Electronically Erasable and Programmable Read Only Memory) 42, and a position information acquisition unit 39 for the user to make a phone call. The position information acquisition unit 39 acquires the current position based on the GPS information from the satellite 1 and the radio wave from the base station 3 and the radio wave from the wireless LAN access point 7 as described in FIG.

  The EEPROM 42 stores a list of shared virtual tags generated by the user in the past. In this list, the geographical position (address) at which the shared virtual tag is created and the note of the user are stored in association with each shared virtual tag. In the example of memo writing in FIG. 5, good youth, friendly, intelligent, etc. are stored as the impression of the other party of the shared virtual tag. In accordance with the operation of the input operation unit 37 of the mobile phone 2 by the user, the list of shared virtual tags stored in the EEPROM 42 is displayed on the display unit 35. The user selects and clicks a shared virtual tag to be accessed with reference to the creation position and the note. Then, the clicked shared virtual tag is displayed together with the generated virtual world of the geographical position by the processing of S80 to S88 described later (see FIG. 2).

  The user can confirm the view around the displayed shared virtual tag in the image of the virtual world, confirm the place where the other party has met, and restore the other's memory from that place. This makes it possible to restore the memory of the other party who has met without knowing the other party's personal information, and it is then possible to decide whether or not to access the shared virtual tag. If the user clicks and accesses the shared virtual tag, a web page for contact is displayed by the processing of S90 to S94 described later, and writing and browsing become possible.

  Next, a block diagram of the hardware configuration of the server 10 and the server 21 is shown in FIG. The functions of the CPU 50, the ROM 51, and the RAM 52 are the same as those described above for the mobile phone 2. The servers 10 and 21 have storage units (not shown). The storage unit is a storage device capable of storing and reading information and data including various programs, files, and large-capacity images as appropriate. These data and programs can be written to the RAM 52 as necessary to perform various information processing. The input unit 55 is configured by a keyboard, a mouse, and the like, and gives the server 10 and 21 instructions for performing various information processing. The interface 58 performs interface processing to the internal bus 57 of various circuits and devices. The display unit 54 is configured of a CRT, an LCD, or the like, and displays characters, figures, and images. The communication control unit 53 manages a communication function of transmitting and receiving data and the like via the Internet 6.

  Next, FIG. 7 shows a flowchart for generating the shared virtual tag described above. In the present invention, not only users in the real world can generate shared virtual tags in the virtual world using the mobile phones A and B, but also users in the real world enter the virtual world and use their mobile phones. It can be used to create virtual world agents (avatars) and shared virtual tags. Also, shared virtual tags can be generated between agents (avatars). Furthermore, users who have entered the virtual world can create shared virtual tags via their agents (avatars). Thus, the agent (avatar) is also stored in the user database 11 as an independent member user so that the agent (avatar) can generate the shared virtual tag independently of the user. For example, as shown in FIG. 4, the user agent ID corresponding to 13B9 PS as the user ID is θ42S15, and this agent (avatar) is also stored in the user database 11 as an independent member user. When the agent ID of θ42S15 is stored in the storage area of the user ID of the user database 11 and the agent of the agent ID itself creates the shared virtual tag, the shared virtual tag ID AP81K7 is the user While being stored in the database 11 (see FIG. 4), position data, virtual tag display data, virtual tag type, and creation date are also stored in the virtual tag database 9 as data of the user ID of θ 42 S15.

  In the flowchart of FIG. 7, one of the parties generating the shared virtual tag transmits data for specifying its own shared virtual tag ID (variable shared virtual tag ID) to the mobile phone of the other party, and the other party Mobile phone transmits its own user ID and the received variable shared virtual tag ID to the server 10, whereby the server 10 identifies the party generating the shared virtual tag and shares it for that party A scheme of generating virtual tags is adopted.

  First, in the mobile phone A or the agent A, a process of calling its own shared virtual tag ID is performed in step S (hereinafter simply referred to as S) 1. The shared virtual tag ID is stored in the built-in memory in the case of the mobile phone A, and is stored as knowledge data for the agent in the case of the agent A.

  Next, in S2, processing for generating a variable shared virtual tag ID is performed using time information of the atomic clock included in the GPS radio wave received from the satellite 1. In this processing, processing such as adding GPS time information to the shared virtual tag ID called in S1 is performed to generate a variable shared virtual tag ID. Then, at S3, the generated variable shared virtual tag ID is transmitted to the mobile phone B by infrared communication. When transmitting to the agent B, the agent B is notified of the variable shared virtual tag ID in the virtual world without using infrared communication. In order to notify the shared virtual tag ID as a variable shared virtual tag ID that has been subjected to processing such as encryption instead of notifying the shared virtual tag ID as it is, the own shared virtual tag ID is stolen to another person Can be prevented as much as possible from being abused.

  In S4 the mobile phone B or the agent B determines whether or not to access the server 10, and when the operation or the decision to access the server 10 is performed, the user ID of the mobile phone B or the agent B is selected in S5. A process of transmitting the contained user authentication data to the server 10 is performed. In the server 10, in S6, based on the transmitted data, the identity verification is performed, and in S7, the access permission is returned to the mobile phone B or the agent B in S7. After receiving the access permission, at S8, an operation of a shared virtual tag generation request is performed, and along with the operation, the current position data and the variable shared virtual tag ID transmitted at S3 are transmitted to the server 10 Then, generation request of the shared virtual tag is made (S9). In the server 10 that has received it, processing to generate a shared virtual tag in the virtual world is performed in S10.

  A flowchart of a subroutine program of the shared virtual tag generation process shown in S10 is shown in FIG. Referring to FIG. 8, in S15, the received variable shared virtual tag ID is composited back to the original plain text, and a process of extracting the shared virtual tag ID and time information is performed. This time information is GPS time information added to the shared virtual tag ID in S2 described above. Next, in S16, it is determined whether the extracted time information is within an allowable error range compared to the current time. When not sending the other user's variable shared virtual tag ID used at the time of previous shared virtual tag generation to the server 10 and making a request to create the shared virtual tag illegally, instead of generating this shared virtual tag this time, Since the current time of day and the time information included in the ID of the variable shared virtual tag transmitted are largely inconsistent, a determination of NO is made in S16, the control proceeds to S20, and the invalid shared virtual tag A process is performed to crack down on the unauthorized user who has made the generation request of.

  Further, in S20, processing is performed to search the virtual tag database 9 for the extracted shared virtual tag ID at the same creation date and time as the extracted time information. Next, in S21, it is judged whether or not there is a corresponding one, and if there is a corresponding one, in S22, the user ID (two or more) of the corresponding shared virtual tags is specified, and in S23 A process is performed to request the portable carrier to specify and deal with the person corresponding to the specified user ID. The carrier who received the request for handling specifies the person and sends a warning letter to the person or cancels the contract of the person when it is too vicious.

  On the other hand, if it is determined that there is no corresponding one in S21, the process proceeds to S24, the user ID is specified from the extracted shared virtual ID, and a request for specifying and coping with the person corresponding to the user ID Against the mobile carrier.

  On the other hand, if a determination of YES is made in S16, the control proceeds to S16a, and a further security check is performed based on whether or not the current positions of the parties generating the shared virtual tag are similar. Specifically, in S16a, a process of acquiring the position of the shared virtual tag generation requester is performed. In the example of FIG. 8, the current position of the mobile phone B or the agent B is acquired. However, when the user of the mobile phone B has explained based on FIG. 2 but accesses a predetermined position in the virtual world, the position of the real world corresponding to the position of the virtual world being accessed is Acquired as the current position. When the agent (avatar) is a shared virtual tag generation requester, the position of the real world corresponding to the current position of the agent (avatar) in the virtual world is acquired as the current position.

  Next, a process of specifying a user ID from the shared virtual tag ID extracted in S15 is performed in S16b. Next, in S16c, processing for acquiring current position information of the user ID is performed. Similar to the current position of S16a, when the user enters the virtual world and accesses a predetermined position, the current position information indicates the predetermined position of the real world corresponding to the predetermined position of the virtual world. Acquire as position information. When the user ID specified from the shared virtual tag ID is an agent (avatar), the position of the real world corresponding to the current position of the agent (avatar) in the virtual world is the current position. It is acquired.

  Next, in S16d, it is determined whether the acquired current position and the current position of the shared virtual tag generation requester are within a predetermined distance. The predetermined distance is, for example, a distance of about 10 meters such that communication can be obtained to mutually obtain consent for generating the shared virtual tag at this location. In the case where it is determined that the distance is not within the predetermined distance, for example, the shared virtual tag ID of another person other than the person who generates the shared virtual tag this time is illegally acquired, and the shared virtual tag ID of the other person is A fraudulent act may be considered such as when a variable shared virtual tag ID using GPS time information is generated by abuse and generated and transmitted. In such a case, a determination of NO is made by S16d, and the control proceeds to S24, and similarly to the above, a request for identifying and coping with the user who has performed such an illegal activity is sent to the mobile carrier Do.

  On the other hand, if YES is determined in S16d, the process proceeds to S17, the user database 11 is searched, and a process of identifying the user ID from the shared virtual tag ID is performed, and the virtual tag database 9 is identified in S18. The stored user ID and the user ID received at the time of access are stored, and processing of storing data of the shared virtual tag in association with the user ID is performed. The state stored in S18 is data of the shared virtual tag corresponding to the user ID of A4VZ12 and B27FH8 in the virtual tag database 9 of FIG.

  Next, in S19, processing is performed to display the shared virtual tag in the virtual world of the received current position. The state is shown in FIG. However, in this display process, it is displayed only on the mobile phone of the party who created the shared virtual tag.

  As described in FIG. 8, as a security measure at the time of shared virtual tag generation, the first stage security check using the time of S16 and S20 to S24, and the shared virtual tag generation person shown at S16a to S16d and S24. The second stage security check is performed based on the current position, and high security can be secured by double security check.

  FIG. 9 is a flowchart showing virtual world display processing performed by the server 10 of the service provider 8. At S30, it is determined whether the user ID and the GPS data have been received. If not received, the control proceeds to S33, where it is determined whether or not the user ID and the access position have been input. If not, the flow returns to S30 again.

  If the member user turns on the GPS function of the mobile phone 2 of his own while traveling through the loop of S30 → S33 → S30, the user ID from the mobile phone 2 and the GPS data indicating the current position of the service provider 8 It is sent to the server 10. Then, a determination of YES is made in S30, and the control proceeds to S31, where processing is performed to convert GPS data (coordinate data consisting of latitude and longitude) of the received current position into position data consisting of an address. Next, in S32, the user database 11 is searched, and processing for updating GPS data and position data corresponding to the received user ID is performed, and the control proceeds to S33. Not only the GPS function of the mobile phone 2 is turned on, but the control may proceed to S31 only after displaying the avatar (agent) of the user in the virtual world.

  On the other hand, if the member user operates his / her mobile phone 2 to access the virtual world and inputs the access position while traveling through the loop of S30 → S33 → S30, the access position and the user ID become the service provider 8 Is sent to the server 10. This access position is not limited to the case where the user operates the mobile phone 2 and inputs the address (position data) that the user wants to access, but the shared virtual tag created by the user in the past and its created location By displaying a list and selecting a shared virtual tag that the user wants to access from the tag list, the location data of the shared virtual tag (see "Position data" in the virtual tag database 9 in FIG. 3) is automatically selected. It may be input.

  When the user ID and the access position have been input, the control proceeds to S34, and it is determined whether the input user ID is registered in the user database 11. When the user is not registered, since the user is not a member user, control is made to display a display of NG on the mobile phone 2 in S35.

  On the other hand, when the input user ID is registered in the user database 11, the control proceeds to S36, and processing of transmitting the input access position to the server 21 of the virtual world provider 20 is performed. When the server 21 of the virtual world provider 20 receives the access position, it searches the virtual world database 22 and reads out the virtual world 3D data portion corresponding to the access position (position data) to the server 10 of the service provider 8 Send. The server 10 acquires virtual world 3D data corresponding to the transmitted access position (S37), searches the user database 11 by S38, and locates an agent (avatar) near the access position, and acquires the virtual Control is performed to overlay and display the agent on world 3D data.

  Next, in S39, a process of searching the virtual tag database 9 and reading out position data of the shared virtual tag corresponding to the input user ID is performed. Next, in S40, it is determined whether the position data read out in S39 is included in the area of the virtual world 3D currently displayed. If not, the control returns to S30. On the other hand, if it is included, the process proceeds to S41, and control is performed to read out the shared virtual tag determined to be included from the virtual tag database 9, and overlay and display it on the virtual world 3D. Next, the process proceeds to S42, the access processing to the shared virtual tag is executed, and the process returns to S30.

  A flowchart of the process of accessing the shared virtual tag is shown in FIG. As shown in FIG. 10, when the user operates the mobile phone 2 to display the list of shared virtual tags stored in the EEPROM 42 on the display unit 35 as described above, YES is determined in S80. Then, the authentication data including the user ID in S81 is transmitted to the server 10. In the server 10 which has received it, the identity of the user is confirmed in S82. When the user having received the access permission in S83 operates the mobile phone 2 to select and click the shared virtual tag to be accessed, an access request to the shared virtual tag in S85 is transmitted to the server 10.

  The server 10 performs the processing in S86 and S87, and as a result, in S88, only the shared virtual tag corresponding to the user ID of the user who has accessed the mobile phone 2, that is, only his own shared virtual tag created by the accessor is displayed. Be done. Therefore, access of persons other than the creator of the shared virtual tag can be blocked. Also, if the shared virtual tag corresponding to the user ID is not stored in the virtual tag database as a result of the search in S86, a message to the effect that the user can not access is returned to the mobile phone 2 or the agent. Also, FIG. 10 shows an example in which the display of the shared virtual tag is performed not only in the virtual world but also in the real world, as indicated by S87 and S88. As a method of displaying a shared virtual tag in the virtual world, for example, a method is conceivable in which a shared virtual tag is displayed at a predetermined location by looking into the real world through a camera function of a mobile phone (Sekai Camera ( Method similar to registered trademark)).

  Also, when the user is generating a plurality of shared virtual tags, for example, the plurality of shared virtual tags and their creation positions are displayed in a list according to time series, and sharing selected and clicked by the user from the tag list If it is possible to jump to the virtual world to which the virtual tag is attached, the convenience of the user is enhanced.

  FIG. 11 is a flowchart showing the operation of the agent (avatar). According to S50, it is determined whether or not another avatar has spoken in the vicinity of the user (agent) in the 3D virtual world, and waits until it is spoken. If it has been spoken, the control proceeds to S51, and a process of popping up notification to the mobile phone 2 of the user corresponding to the spoken is performed. Next, in S52, a conversation is conducted corresponding to the story, and control is performed to display the content of the conversation on the mobile phone 2.

  Next, in S53, it is determined whether the user himself / herself desires to have a conversation. This is determined depending on whether or not the user operates his / her mobile phone 2 to display a desire to talk. If the user himself / herself does not desire a conversation, it is determined in S54 whether the conversation has ended or not, and if the conversation has not ended yet, the control returns to S52.

  On the other hand, when the user himself / herself desires to have a conversation, the control proceeds to S55, and control is performed to switch to the user's own conversation and continue the conversation. Next, in S56, it is determined whether or not the conversation has ended, and if it has not ended, the processing of S55 is continued. Then, when the conversation is finished, the process returns to S50.

  In this way, since the user's agent (avatar) will handle at first when spoken by other avatars in the virtual world, the user confidence does not have to constantly monitor the virtual world, and is only interested in the real world Can be

  Also, the agent (avatar) may be a resident agent that resides on a user terminal (for example, mobile phone 2 or the like). In this case, it may be a mobile agent which is usually stored in the database of the service provider 8 (for example, the user database 11 or the like) or a user terminal, and moves to a necessary place as needed.

  There are two types of agents (avatars) displayed in the virtual world. First, the virtual world is displayed at the geographical position of the virtual world corresponding to the current position of the user in the real world, and the first agent capable of interacting with the virtual world and the first agent capable of talking with the virtual world. Is the second agent for displaying In the virtual world, it is desirable to be able to distinguish between the first agent and the second agent in appearance. When an intruder into the virtual world encounters another agent (avatar), the agent (avatar) is an agent of the user in the real world (avatar) or an agent of the intruder into the virtual world (avatar) In order to distinguish whether or not to talk and to select the content of the talk.

  FIG. 12 is a flowchart showing generation control of a business-use shared virtual tag. This business-use shared virtual tag is for creating a community in which the attendee who has visited an event such as an exhibition or a concert and the organizer or the attendee can make contact later. The "event" in the present invention is a broad concept encompassing various promotions, concerts, live performances, etc. as well as exhibitions, and is a concept encompassing all the events where a large number of people gather. It also encompasses not only events held in the real world, but also events held in the virtual world.

  In the case of an event held in the real world, a mobile phone is used as a terminal of each attendee in the same manner as described above in generating a shared virtual tag (community) between the organizer and each attendee. A shared virtual tag (community) is generated using the wireless LAN access point 7 that covers the event site as a communication area as the terminal on the side. On the other hand, in the case of an event held in the virtual world, a shared virtual tag (community) is generated by the communication between the agent (avatar) of each attendee and the hall agent constituting the virtual event hall.

  FIG. 12 performs control similar to that of FIG. 7 described above, and here, mainly the differences will be described. In FIG. 12, steps similar to those in FIG. 7 are assigned the same step numbers.

  First, the wireless LAN access point 7 or the venue agent on the event host side determines whether the event start time has come and waits until the event start time comes. When it is determined that the event start time has come, personal authentication data including the user ID of the self (host side) is transmitted to the server 10. The server 10 performs identity verification based on the received data in the same manner as in FIG. 7, and returns an access permission on the condition that the identity has been verified (S7). The wireless LAN access point 7 or the venue agent having received it transmits the scheduled start time and the scheduled end time of the event to the server 10 in S101. The server 10 stores the scheduled start time and the scheduled end time of the received event (S102).

  On the other hand, the participant who has agreed to generate a shared virtual tag (community) with the organizer executes the processing of S1 to S3 by the mobile phone 2 or the agent (avatar) as in FIG. Since the processes of S1 to S3 are executed by each mobile phone 2 (or agent) of the participant who has agreed to generate the shared virtual tag (community), the process is repeatedly executed by the number of the agreed participant (S103). The wireless LAN access point 7 or the venue agent receiving the variable shared virtual tag ID transmitted each time receives the current location data of the wireless LAN access point 7 or the venue agent and each variable shared virtual tag, as in FIG. The server 10 transmits the ID for use with the server 10 to request generation of a shared virtual tag (community) (S9).

  The server 10 that has received it determines whether the reception time is between the scheduled start time and the scheduled end time received in S102, that is, within the event holding time (S104). If it is determined that it is not within the holding time of the event, the control ends without generating a business-use shared virtual tag. On the other hand, if it is determined that it is within the holding time of the event, a business-use shared virtual tag generation process is executed in S105.

  A flowchart of a subroutine program of this business-use shared virtual tag generation processing is shown in FIG. The flowchart of FIG. 12 is similar to the flowchart of FIG. 8 and the same control steps are indicated with the same step numbers and the contents of the steps are omitted.

  Each step of S15, S16, S16a, S16b, S16c, S16d, and S17 to S24 is the same as the control content of each step shown in FIG. However, in S16d of FIG. 8, it was determined whether within the predetermined distance whether it is within the predetermined distance or not within the range of about 10 meters, but in this business-use shared virtual tag generation process, it is within the range of the event hall. It is judged whether it is a distance or not. After the control of S17, the control proceeds to S200, and it is determined whether the specified user ID (user ID on the sponsor side) is already stored in the virtual tag database 9. If it is not stored yet, that is, if it is the first request for generation of a business-use shared virtual tag (community), the control proceeds to S18. On the other hand, if it is determined in S200 that the specified user ID (user ID on the organizer's side) is already stored in the virtual tag database 9, control proceeds to S201 and the virtual tag database 9 is accessed. At the same time, processing is performed to store the user ID received and to store data of the shared virtual tag in correspondence with the user ID. Thereafter, control proceeds to S19.

  As a result of such business-use shared virtual tag generation processing, a shared virtual including all participants who agreed to the generation of the business-use shared virtual tag within the event holding time and performed the tag generation operation and the organizer side Tags are generated. By accessing the shared virtual tag for business use, the community page generated in advance by the organizer is displayed, and various notifications and messages from the organizer are displayed on the participant. In addition, a participant's side write page is prepared, and when the participant writes there, communication between the participants and between the participant and the organizer becomes possible.

Modification of First Embodiment
Next, modified examples of the first embodiment will be listed.

  (1) In the above detailed description, although an example is shown taking advantage of the virtual world that the user can freely move to the desired location anytime anytime, the merits of the virtual world are not limited to this. As described above, in the virtual world, various virtual tags (see FIG. 3) can be accumulated and displayed in time series in addition to the shared virtual tags, and the user accesses the past virtual tags and browses and writes in the tags. It is possible. That is, the virtual world is a so-called four-dimensional space-time world in which data can be stored and viewed along the time axis, as well as three-dimensional space. Taking advantage of the characteristics of this four-dimensional space-time world, a variety of attractive services will be possible.

  For example, when accessing the virtual world, not only the access location but also the past date and time you want to access are specified, so that the designated date and time of the specified location can be accessed. For example, if you specify Tokyo Akihabara as the access location and June 8, 2008 as the past date and time you want to access, you can access the virtual tag created on the day of the Assassination case as it occurred in Tokyo Akihabara on June 8, 2008. , You can view the situation and shooting video of the time. In addition, it becomes possible to exchange information with the person who created the virtual tag via the virtual tag.

  As another example, various incidents and events that occurred in the past are displayed in a list together with the date and time of occurrence and the location of occurrence, and by selecting and clicking from within the list, a virtual space of the corresponding date and time of the corresponding location is displayed. You may be able to jump.

  By accumulating virtual tags in a virtual space-time that enables time-machine-like access that also uses the time axis in this way, the virtual space-time can be grown into a huge historical database. Moreover, since the accumulation of data in this historical database is conducted by a large number of users themselves, it is possible to construct a huge historical database without any cost.

  (2) In the above detailed description, the avatar (agent) as the user's alternate personality corresponding to the user is shown, but in addition, an independent character (agent) not corresponding to any user is made into a virtual world You may let them live. This character (agent) is composed of an intelligent agent that is programmed to talk to a user who has entered the virtual world, and each character (agent) has its own individuality. The user who has entered the virtual world finds out the character (agent) most matching him / her and performs intellectual interaction in the virtual world. This is also a modification of the second embodiment described later.

  (3) In the above detailed description, an example in which two persons create a shared virtual tag is shown, but the number of persons is not limited to this and may be three or more. In addition, after the creation of the shared virtual tag, a third party to whom all creators of the shared virtual tag have permitted access may access the shared virtual tag later. As an example of access control, first, the third party notifies the shared virtual tag creator of the exact location and creation date of the shared virtual tag. This information is needed to identify the shared virtual tag to be accessed. Next, as evidence that all the creators of the shared virtual tag are allowed access, all of the creators are notified of the variable shared virtual tag ID. Then, the notified information is transmitted to the server 10 to have the access right granted.

  (4) A memo function may be provided which can be written and viewed by only one of the shared virtual tag sharers. With this memo function, for example, it is possible to make a memo (write and record) things that you do not want the other person to read, such as the first impression of the other person, the opportunity to meet, the situation at that time, etc. The virtual tag can be accessed to determine whether to make contact with the other party.

  (5) In the above embodiment, the display of the shared virtual tag in the virtual world is described, but the present invention is not limited thereto, and the virtual world may be eliminated to allow the user terminal to directly access the shared page for contacts. Good.

  Specifically, in the flowchart of the shared virtual tag generation process described above, instead of the step of S19, “the mobile phone of the user ID specified from the received ID for the variable shared virtual tag and the mobile phone of the shared virtual tag generation requester Send the shared virtual tag to the phone. By this processing, the shared virtual tag is stored not in the virtual world but in the terminal (such as a mobile phone) of the party. If the party selects and clicks a shared virtual tag stored in his / her mobile phone that he / she wants to access, the designation of the shared virtual tag clicked is transmitted to the server 10 by the above-described S90, and after S91, Control is performed.

  In the case of this simplified system, since the shared virtual tag is not displayed in the virtual world of the predetermined geographical position such as the place where it meets, the memory at the time of encounter can not be traced from the geographical position. Therefore, it is preferable to display the shared virtual tag on the mobile phone together with information (such as an address) that can specify the geographical position at which the shared virtual tag was generated.

  (6) One party of the shared virtual tag may be able to cancel. The server 10 that has received cancellation request information (including the user ID of the person) from the mobile phone 2 searches the virtual tag database 9 and stores cancellation information (flag etc.) in association with the received user ID. As a result, even if there is writing from the other party of the canceled shared virtual tag, control is performed so that the pop-up notification to the cell phone 2 of the canceler is not performed.

  (7) A method may be employed to prevent a stalker act that abuses the virtual world, which follows a user moving in the real world in the virtual world. Specifically, when the user previously registers a specific area such as near home or near work in the user database 11 of the service provider 8 and overlays and displays the avatar (agent) on the virtual world in S38, Control is performed so that avatars (agents) are not displayed in the registered specific area. This is also a modification of the second embodiment described later.

  (8) It is desirable to have a place where you can make contact later, even when you are told to create a shared virtual tag. For example, first, not only the update of the position data in S32 but also the past position data and time data are stored in the user database 11 as a history. Then, in the real world, the virtual world, or between the virtual world and the real world, register the geographical position and the time that you met (when you meet) when you meet or during the meeting with the other person. After that, when it is desired to contact later, the server 10 is searched for a partner who matches the registered geographical position and time, and a contact is offered to the searched partner (for example, An offer of shared virtual tag generation is made to the other party via the service provider 8).

  The search for the other party specifies the other party of the history data matching the geographical position and the time when the contact offerer specified, based on the history data of the position data and the time data stored in the user database 11 . As registration of the geographical position and time (date of encounter registration), the user operates the mobile phone 2 to register the mobile phone 2 itself or have the user database 11 registered by the server 10. As the time for registration, it is preferable to search for the other party, such as an arbitrary time in the middle of meeting the other party, a time separated from the meeting time, or a time when the separated time was met. It is desirable that the encounter point registration be registered in the user database 11 by the server 10 at the encounter point in order to prevent an offer of a contact by impersonation or the like. In that case, the step which changed above-mentioned S4-S7 and S8 into "a meeting point registration request operation", the step which changed S9 into "a request of a meeting point registration by transmitting geographical location data and time data which met" , S10 is changed to the "onset point registration process" and the step is executed. Then, in the encounter time registration process, the current position of the encounter time registration requester is acquired based on the transmitted user ID, and the transmitted geographical position data is within a predetermined distance (for example, within 10 meters). And that the transmitted time data and current time are within the allowable range, the transmitted geographical position data and time data are registered in the user database 11 in association with the user ID. Do.

  Note that if the other party agrees to the offer for shared virtual tag generation, the shared virtual tag is generated at the place where the user met, etc., but the other party is not in contact with the shared virtual tag. If notification of the telephone number is desired, and the offerer of shared virtual tag generation agrees with it, it is sufficient to exchange the mail address and the telephone number with each other, and it is not necessary to necessarily generate the shared virtual tag.

Second Embodiment
Next, a second embodiment will be described. The virtual world in the first embodiment described above mainly targets only the current virtual world, which will be described below. In the second embodiment, not only the present virtual world but also the past virtual world and the future virtual world are covered.

  In the second embodiment, in addition to the server described in the first embodiment, for example, control flowcharts of various computers such as a police server, an advertiser client, an advertiser server, and a shopkeeper client are described. There is. The hardware configurations of various computers appearing for the first time in the second embodiment are the same as those described with reference to FIG. 6 in the first embodiment, so in the second embodiment, the hardware of the various computers is described. The repetition of the description of the wear configuration is omitted.

  First, the user four-dimensional coordinate database 11a will be described with reference to FIG. The user four-dimensional coordinate database 11a is a modification of the user database 11 shown in FIG. 4 in the first embodiment. Here, differences from the first embodiment will be mainly described.

  The user four-dimensional coordinate database 11a stores data of user ID, shared virtual tag ID, agent ID, current position (GPS data etc.), position data, and schedule. The schedule is data in which the user himself operates the mobile phone 2 and inputs a future schedule, as will be described later, and is data of the future. For example, if it is planned to participate in the ○ event on a certain date, the user inputs data of the ○ event, date, and place from the mobile phone 2 and the data corresponds to the user ID in the user four-dimensional coordinate database 11a. Will be stored.

  The current position (GPS data etc.) is composed of latitude data x and longitude data y and altitude (altitude) data z. This data is indexed by combining GPS data from the mobile phone 2 owned by the user, radio waves from the base station 3 connected to the mobile phone network 4 and radio waves from the wireless LAN access point 7 It is position data. For example, in the case of a user whose user ID is 1R37P8, latitude x = 35.69419, longitude y = 139.714849, and sea level (elevation) z = 28 mm. The data of z is, for example, the height at which the user enters a high-rise building or the like and the radio wave from the access point 7 installed on the floor of the building is received by the mobile phone 2 and specified from the access point 7 It is data of (altitude). When the user has not entered a high-rise building or the like, “z = unknown” as shown in FIG. 13 because elevation data is unknown.

  The data of the current position changes as the user moves. In the second embodiment, the history of the change is stored along the time axis w retroactive to the past. That is, the user four-dimensional coordinate database stores three-dimensional data of x, y, z and history data changing along w which is a time axis, thereby storing data of four-dimensional coordinates. It will be done. The position information (x, y, z) is stored in the user four-dimensional coordinate database 11a according to the above-described S30 to S32, and the user four-dimensional coordinate database 11a cumulatively stores the past position information (x, y, z) In order to do this, position information x, y, z along the time axis w is stored in the user four-dimensional coordinate database 11a.

  Moreover, since data of “schedule” is also stored, not only the past position data of the user but also future scheduled data are stored.

  The user ID “θ 42 S 15” is an ID of the user himself / herself for handling the agent himself as a user, as described in the first embodiment.

  Next, with reference to FIG. 15, a flowchart showing a program of a main routine of the mobile phone 2 and the server 10 of the service provider 8 in the second embodiment will be described.

  Referring to FIG. 15A, in the mobile phone 2, virtual world terminal processing is currently executed in S300, past virtual world terminal processing is executed in S301, future virtual world terminal processing is executed in S302, and authentication is performed in S303. The terminal process is executed, the virtual world advertising terminal process is executed in S304, the marketing terminal process is executed in S305, and then the process returns to control S300.

  Referring to FIG. 15B, the server 10 executes the present virtual world correspondence processing in S310 in S310, the past virtual world correspondence processing is performed in S311, the future virtual world correspondence processing is performed in S312, and the authentication in S313. The processing is executed, the virtual world advertisement correspondence processing is executed in S314, the marketing correspondence processing is executed in S315, and then the control returns to S310.

  The current virtual world terminal processing and the current world virtual world response processing are processes for providing various services utilizing the current virtual world. The past virtual world terminal process and the past virtual world response process are processes for providing various services utilizing the past virtual world as a stage. The future virtual world terminal processing and the future virtual world processing are processes for providing various services using the future of the virtual world as a stage. The authentication terminal process and the authentication process are processes for performing authentication using four-dimensional coordinate data stored in the user four-dimensional coordinate database of FIG. Virtual world advertisement terminal processing and virtual world advertisement correspondence processing are to display advertisements in the virtual world and to enable monetization by revenue from advertisers. The marketing terminal processing and the marketing correspondence processing are processings for collecting historical data of user's actions (movement of place and time) in the virtual world (four-dimensional space-time) and utilizing it for marketing. Details of each of these processes will be described later.

  FIG. 16 (a) is a flowchart showing a subroutine program of the current virtual world terminal process shown in S300 of FIG. 15 (a). Referring to FIG. 16A, in the current virtual world terminal process, shared virtual tag terminal processing is performed in S320, virtual world display terminal processing is performed in S321, and emergency terminal processing is performed in S322, and S323. The terminal processing at the time of disaster is performed, the cyber special zone terminal processing is performed at S324, the common point search request processing is performed at S325, the community virtual tag terminal processing is performed at S326, and the link source designation terminal processing is performed at S327. It will be.

  FIG. 16 (b) is a flow chart showing a subroutine program of the current virtual world correspondence processing shown by S310 in FIG. 15 (b). Referring to FIG. 16B, in the current virtual world response process, the common virtual tag response process is executed in S330, the virtual world display response process is executed in S331, and the emergency response process is executed in S332, The disaster response process is executed in S333, the cyber special zone response process is executed in S334, the common point search process is executed in S335, the community virtual tag response process is executed in S336, and the user four-dimensional coordinate search process is executed in S337. Is executed, and in step S338, a link source designation corresponding process is executed.

  Specifically, the shared virtual tag terminal processing and the shared virtual tag correspondence processing are the control shown in FIGS. 7, 8 and 10 to 13. The virtual world terminal process and the virtual world display correspondence process are processes in which the user enters the virtual world and displays the virtual world corresponding to the entering place and time. The virtual world display handling process will be described later based on FIG.

  Emergency terminal processing and emergency response processing are processing for displaying a message such as "Please help me!" In the virtual world corresponding to the current position of the user when the user encounters an emergency and asks for help. It is. The message of "Please help!" May be displayed as a virtual tag in the real world of the user's current position as well as in the virtual world. Then, when the user moves, the mobile phone 2 possessed by the user also moves, and it is controlled so that the message in the virtual world and the real world is also moved and displayed as the mobile phone 2 moves.

  In addition, when this emergency terminal process is executed, it may be controlled by the server 10 so as to automatically notify the police, a security agency, a medical institution or the like. Furthermore, an emergency shelter (a convenience store, a gas station, or a public facility always standing by, such as a police fire department) may be displayed on the mobile phone 2 of the user who has performed an operation for executing an emergency terminal process. .

  The terminal process at the time of disaster and the process at the time of disaster are processes for displaying and controlling in the virtual world the position display necessary at the time of disaster such as a shelter, a hospital, a fire department or a police at the time of disaster. This position display process uses a virtual tag dedicated for disasters that differs from a normal virtual tag. That is, the control operation is performed independently as the disaster information providing system, the provision of information, communication, messages and the like are created and displayed by the disaster dedicated virtual tag. As a result, it is possible to provide accurate information at the time of disaster, avoiding confusion of information at the time of emergency. As the information to be provided, in addition to the display of the above-mentioned location information, provision of information on disabled persons at hospitals and shelters, provision of comprehensive information on disasters, display of emergency messages at shelters etc. Do.

  The cyber special zone terminal process and the cyber special zone handling process are control processes in a cyber space defined by a government or the like to apply special rules different from the social rules applied to the real world. For example, a virtual world to which a user can enter is structured in multiple layers, the first layer is a cyber space to which the same social rules as the real world are applied, and the second layer is, for example, a high consumption tax rate (eg, 20%) The social rules are applied, and the social welfare that accompanies it is a cyberspace that is full, and the third hierarchy is configured to be, for example, a cyberspace to which a symbiotic economy is applied (symbiotic economic cyberspace).

  The symbiotic economy forms the self-sufficiency area (referred to as the FEC self-supply area) of F (foods = food), E (energy) and C (care = human relations in a broad sense) at the citizen level. In the symbiosis economic cyber special zone, an economic zone independent from the monetary economy by the yen in Japan is established by solidarity, participation and collaboration. On top of that, we will make effective use of the cyber space and contribute to the formation of the FEC self-sufficiency area.

  In order to establish an economic sphere independent of the monetary economy by yen, for example, the unique virtual currency within symbiosis economic cyber special zone is issued, and the currency or yen is directly currency based on the change system, using the virtual currency. Make external trades with the countries that are trying to make it, thereby making the symbiosis economic cyber special zone economically independent of the real world.

  Furthermore, in place of the issue of the virtual currency, "respect figures" in the respect market may be introduced in addition to that. The "respect number" is value information that represents the respect for the other party. Recognize at least a part of the function of money (exchange value and value standard (scale)) in "respect figures" accumulated from others. This can provide motivation other than the economic benefits for developing a voluntary economy.

  The common point search request process and the common point search process are processes for searching for a common point such as an action place between a certain user and another user. The details will be described later based on FIG.

  Community virtual tag terminal processing and community virtual tag handling processing are virtual worlds where community virtual tags that exchange opinions etc. about events that occur in the real world (eg guerrilla live or total solar eclipse etc.) correspond to the occurrence location of the events. And processing to generate in the real world. The details will be described later based on FIG. 18 to FIG.

  The link source specification terminal process and the link source specification correspondence process refer to the case where the user writes a blog or the like based on the user's conversation or action history stored as a history in the virtual world (on four-dimensional coordinates). The trackback process is performed to put a hyperlink on the action history on which it is based. Details will be described later based on FIG. 22 and FIG.

  The user four-dimensional coordinate search process is a process for searching for a user located in a certain closed space in four-dimensional coordinates from a predetermined organization such as the police. For example, when a murder case occurs at a certain time at a certain place, the time of occurrence and the user (witnesses etc.) who were in the vicinity of the occurrence place of the murder case to be interviewed should be searched and indexed Use it sometimes. The details will be described based on FIG.

  FIG. 17 is a flowchart showing a subroutine program of the common point search request process shown in S325 of FIG. 16 and the common point search process shown in S335. The common point search request process is for searching for geographical common points in the behavior of the users as described above, and is executed between the mobile phones A or B or the agents A or B of the user. First, it is determined in S370 whether the common point search operation has been performed in the mobile phone A or the agent A. If there is an operation to search for common points with each other, YES is determined in S370, and the process proceeds to S371, and processing for reading out the shared virtual tag ID is performed. This is processing for reading out the shared virtual tag ID stored in the EEPROM 42 in the case of the mobile phone A, and in the case of the agent A, the shared virtual tag ID stored as knowledge data by the agent A It is a process to read out.

  Next, control proceeds to step S372, and processing for generating a variable shared virtual tag ID is performed using GPS time information. This process is the same as the process of S2 in FIG. 7, and the description thereof will not be repeated here. Next, in S373, processing for transmitting the variable shared virtual tag ID to the mobile phone B or the agent B is performed. In the mobile phone B or the agent B, it is first determined in S376 whether or not there is a common point search operation, and if there is not, this subroutine program is ended. The variable shared virtual tag ID transmitted from A is received. Next, in S378, it is determined whether or not the server 10 is to be accessed, and the process waits for access. Then, when the user operates the mobile phone B and performs an operation to access the server 10 or when the agent B determines that the server 10 is to be accessed, a determination of YES is made in S378 and the control is performed. The process advances to step S379 to transmit personal authentication data including the user ID to the server 10.

  The server 10 receives it (S 384), performs identity verification in S 385, and sends an access permission to the mobile phone B or agent B in S 386. These steps S378, S379, and S384 to S386 are the same as the processes of steps S4 to S7 in FIG.

  The mobile phone B or the agent B receives the access permission transmitted from the server 10 (S380), and according to S381, the current position data of the mobile phone B or the agent B and the variable shared virtual tag of the mobile phone A or the agent A A process of transmitting the ID and the server 10 and requesting a search for common points is performed.

  The server 10 receives it (S387), and executes the processing of the same steps as S16, S16a to S16c, S16d, and S20 to S24 shown in FIG. Next, when a determination of YES is made in S16d, the control proceeds to S388, and the user four-dimensional coordinate database 11a of both the mobile phones A and B or agents A and B is searched, and data in which only both positions are common And data whose position and time are common. Next, in S389, the identified data is transmitted to the mobile phone A or agent A and the mobile phone B or agent B. The cellular phone A or the agent A receives it (S 374), and displays the received data (S 375). The mobile phone B or the agent B receives the data transmitted at S 389 (S 382), and displays the received data (S 383).

  By this control, it is possible to confirm that the holder of the mobile phone A and the holder of the mobile phone B or the agent A and the agent B mutually share geographically in their own actions. For example, they can identify each other's common points, such as watching each other at the 2010 FIFA World Cup, going to the same restaurant for a meal, etc., and can provide materials useful for subsequent communication.

  Furthermore, not only one party (mobile phone B or agent B) alone issues a search request for common points, but the other party (mobile phone A or agent A) transmits a variable shared virtual tag ID Since a search request for common points can be issued under the conditions (see S373 and S377), common points (personal information) can be exchanged under agreement between the parties, and privacy issues can be cleared.

  FIGS. 18 to 20 are flowcharts showing subroutine programs of the community virtual tag terminal process shown at S326 in FIG. 16 and the community virtual tag corresponding process shown at S336. First, in the server 10, it is determined in S410 whether or not there is an input operation of an event, and if there is not, the process proceeds to S412. For example, when an event such as a total solar eclipse, a tornado or a guerilla live by a famous entertainer occurs, the employee (operator) of the service provider 8 places the occurrence location and the occurrence time of those events considered to be important to the server 10. input. For example, in the case of a total solar eclipse or a tornado, x, y, z representing the occurrence location as well as the user four-dimensional coordinate database 11a shown in FIG. It is input as four-dimensional coordinate data consisting of time change w. Then, a determination of YES is made in S410, and the process proceeds to S411, in which the event name, the occurrence location, and the occurrence time are stored in an event four-dimensional coordinate database (not shown).

  On the other hand, in the mobile phone 2, it is determined in S400 whether the community virtual tag has been operated or not. If not, the control proceeds to S424 shown in FIG. 20, and the community virtual tag is accessed or not. If not, the subroutine program of the community virtual tag terminal process ends. On the other hand, when the user operates the mobile phone 2 and inputs the operation of the community virtual tag, YES is determined in S400 and the process proceeds to S401, and it is determined whether or not the storage operation of the current position and time has been performed. If not, it is determined in S403 whether or not a community virtual tag generation operation has been performed. If not, the subroutine program of the community virtual tag terminal process is ended.

  On the other hand, when the user accidentally encounters a guerrilla live or a tornado, the mobile phone 2 performs an operation of storing the current position of the encounter place and the current time. Then, YES is determined in S401, and the current position and time, that is, the position (x, y, z) where the guerrilla live or tornado is encountered and time (w) are stored in the EEPROM 42 in S402.

  Next, when the user operates the mobile phone 2 and performs an operation for generating a community virtual tag, YES is determined in S403, and the control proceeds to S404 to select the storage information stored in S402 described above. A determination is made as to whether or not an operation for designating has been input, and if it has not been performed, a determination is made as to whether or not an input operation of the access position and time has been made in S405. , S404 → S405 → S404 in a loop. When the user wants to generate a community virtual tag related to an event already stored in the mobile phone 2 based on, for example, the process of S402, the user selects an event to be generated from the stored information. Then, YES is determined in S404, the process proceeds to S406, the position and time of the selected input and the user ID are transmitted to the server 10, and a process of requesting generation of a community virtual tag is performed.

  On the other hand, when the user encounters an event (for example, guerrilla live or tornado) but does not store the current position and time at the time of the encounter, I would like to create a community virtual tag for the encountered event In this case, the location and time of the encounter are manually input to the mobile phone 2 based on its own memory. Then, a determination of YES is made in S405, and control proceeds to S406, and the input position and time and the user ID are transmitted to the server 10, and generation of a community virtual tag is requested.

  The server 10 receives the generation request of the community virtual tag from the mobile phone 2 (S412), and determines in S413 whether or not the community virtual tag has already been generated at the received position and time. If it has been generated, the control proceeds to S 414, and the fact that it has already been generated is sent back to the mobile phone 2. The user can access the already generated community virtual tag.

  On the other hand, when the community virtual tag has not been generated yet, the control proceeds to S415, and it is determined whether or not storage of the event corresponding to the received position and time has already been made. This is a determination as to whether or not the event name, the place of occurrence, and the time of occurrence are already stored at S411 described above, and the employee of the service provider 8 operates the server 10 to store the event already. If yes, the control proceeds to S416, generates a community virtual tag at the occurrence location of the event, displays the occurrence time of the event on the community virtual tag, and further the community name entered by the service provider 8 employee Is displayed, and the subroutine program of this community virtual tag correspondence processing ends. As a community name, for example, "Mr. ○ Mr. Shibuya Dogenzaka Guerrilla live going!

  On the other hand, when the determination of NO is made in S415, the control proceeds to S421. In S421, a process of transmitting an input request for the occurrence time of an event to the mobile phone 2 is performed. The portable telephone 2 receives it (S 417), displays an input screen of the occurrence time of the event by S 418, judges whether or not the user has performed an input operation of the occurrence time by S 419, and waits until it is. Not only the occurrence time of the event but also the input screen of the community name may be displayed to allow the user to input the community name.

  If the user operates the mobile phone 2 to input an occurrence time of an event, the control proceeds to S420, and processing for transmitting the input time to the server 10 is performed. In the server 10, it is received (S422), and the control then proceeds to 423 to generate a community virtual tag at the position received in S412 and display the time received in S422 as the occurrence time of the event. .

  If NO is determined in S400 and YES is determined in S424, the control proceeds to S425, and processing for transmitting the information specifying the community virtual tag of the access destination and the user ID to the server 10 is performed. It will be. As information for specifying the community virtual tag of the access destination, for example, data for specifying a place or a place where the community virtual tag is generated and a time can be considered. As another example, as described in FIG. 5, the community virtual tag is stored in the EEPROM 42 in the same manner as the shared virtual tag, and the user performs an operation of displaying a list of community virtual tags and displays the list. By selecting and clicking on a community virtual tag to be accessed from among them, the clicked community virtual tag may be automatically specified and transmitted to the server 10.

  The server 10 receives the information transmitted in S425 (S432), and searches the community virtual tag database (not shown) by searching the position of the designated community virtual tag and the occurrence time of the event in S433. Next, control proceeds to step S434, and the four-dimensional coordinate data (w, x, y, z) of the user specified from the user ID received in step S432 and the position (x, y, z) of the community virtual tag extracted A process of collating with the occurrence time w is performed. Then, in S435, it is judged whether or not the two match, and if the two do not match, the access denial is returned to the mobile phone 2 in S436. On the other hand, if it is determined in S435 that the both match each other, the control proceeds to S437, transmits the page of the accessed community virtual tag to the mobile phone 2, and controls the mobile phone 2 to display the page. .

  The mobile phone 2 receives the page of the access refusal or community virtual tag in S426, determines whether or not the access refusal is received in S427, and when the access refusal is received, the access refusal is mobile in S428. In the case where it is not received the access denial, the process proceeds to S429, and processing is performed so that the page of the community virtual tag can be extracted and browsed.

  Next, in S430, when the user writes a message or a sentence in the page, a process of transmitting the written information to the server 10 is performed. In the server 10, processing of storing the written information in the community virtual tag database is performed in S438. Specifically, the write information is stored in association with the corresponding community virtual tag. Next, when the user operates the mobile phone 2 to perform an ending operation (S431), the ending operation signal is transmitted to the server 10, and the processing for ending the community virtual tag corresponding process in the server 10 is performed in S439.

  In the community virtual tag terminal process and the community virtual tag handling process described above, only the mobile phone 2 of the user who was in the vicinity of the occurrence location at the occurrence time of the event of the community virtual tag to be accessed as a result of access control in S434 to S437. Will be allowed access. However, the present invention is not limited to this, and access may be made by the mobile phone 2 of the user who was at another place at the occurrence time of the event. In this case, a difference may be made between an encounter user who has encountered an event and a non-encounter user who has not encountered an encounter regarding a write restriction or the like in a page of the community virtual tag. For example, in the case of non-encountered users, only pages for non-encountered users can be written and read, while in the case of encounter users, they can write and read in pages dedicated to encountered users and also in pages for non-encountered users Make it available for viewing.

  FIG. 21 is a flow chart showing a subroutine program of the user four-dimensional coordinate search process shown in S337 of FIG.

  Processing of a user four-dimensional coordinate search request is executed at a server (not shown) installed at the police station. First, in S450, the data for personal identification is transmitted to the server 10 and a search request is made. The personal authentication data is, for example, composed of an electronic certificate (or attribute certificate) or the like issued by a predetermined authentication organization that has authenticated that it is a police server. The server 10 receives the search request (S454), confirms that the server is a legitimate police server at S455, and then sends a response to the police server indicating that permission is to be given.

  The police server receives it (S451), and transmits the next data as a search target range by S452.

a ≦ w b b c x x d de y y f f z This data is received by the server 10 (S456), and the user within the received search target range is the user four-dimensional coordinate database according to S457. A process of searching from 11a is performed. Next, in S458, the search result is transmitted to the police server, and the police server receives it in S453.

  Thereby, for example, when conducting a hearing investigation etc. when a murder case occurs, it is possible to easily find out the people (witnesses) who were in the vicinity of the occurrence place during the occurrence time zone of the murder case and there is no waste It has the advantage of being able to conduct hearings and investigations.

  FIG. 22 is a flowchart showing a subroutine program of the link source designation terminal process shown in S327 of FIG. 16 and the link source designation corresponding process shown in S338. In the mobile phone 2, it is determined in S460 whether or not there is a link source designation operation, and if there is not, the subroutine program of link source designation terminal processing ends. For example, the user enters the virtual world of the time and place of occurrence of the indiscriminate murder case to interview on a certain subject such as the indiscriminate murder case, for example, and talks to the avatar (agent) of the user who was in the vicinity If you write a blog etc. based on it, you want to embed a hyperlink in your blog with the site of the coverage (content of conversation in the virtual world etc.) as the link source and you want to track back the link source The user operates the mobile phone 2 to perform a link source designation operation. Specifically, the four-dimensional coordinates (w, x, y, z) at the start of the conversation by coverage or the like are input. Then, YES is determined in S460, and the input start point coordinate data of the link source space-time is transmitted to the server 10 in S461.

  The server 10 receives it (S 467), and stores the URL specifying the space-time of the four-dimensional coordinates of the designated start point in the hyperlink database 60 (see FIG. 23) in S 468.

  Further, in S <b> 462, the cellular phone 2 inputs four-dimensional coordinates (w, x, y, z) at the end of coverage (conversation). Then, processing of transmitting coordinate data (w, x, y, z) specifying the end point of the input link source space-time to the server 10 is performed. The server 10 receives it (S469), and stores the URL specifying the space-time of the four-dimensional coordinates of the designated end point in the hyperlink database 60 in S470.

  Next, in the server 10, processing of transmitting the start point URL stored in the hyperlink database 60 (see FIG. 23) to the mobile phone 2 is performed in S471. The mobile phone 2 receives it (S463), and in S464, the received start point URL is embedded in the linked content (for example, blog etc.). Next, in S465, a determination is made as to whether the user has performed a trackback operation, and when the trackback operation is performed by operating the mobile phone 2, the control proceeds to S466 and the URL of the link destination content (blog etc.) is tracked back A process of transmitting to the server 10 is performed.

  The server 10 receives it (S 472), and stores the received URL as a link destination URL in the hyperlink database 60 (see FIG. 23) in S 473.

  FIG. 23 is a diagram for explaining storage data of the hyperlink database 60. As shown in FIG. The hyperlink database 60 is installed in the service provider 8 and the server 10 writes and reads data.

  The hyperlink database 60 stores data of a start point URL, an end point URL, a link destination URL, and comment data. For example, http: // abc as the start point URL, http: // opq as the end point URL, and http: // hij as the link destination URL are stored. For example, http: // abc is transmitted to the mobile phone 2 as the start point URL, and the user embeds the received http: // abc in the content (blog or the like) according to the above-described S471. If another person accesses the content (blog etc.) and clicks the embedded start point URL http: // abc, it jumps (moves) to the virtual space (four-dimensional coordinate space) specified by the URL Can be accessed. Thereafter, while time passes to the virtual space (four-dimensional coordinate space) specified by the end point URL http: // opq, the conversation such as the coverage contents of the user is displayed with the passage of time in the virtual space It becomes. Then, another person who sees the exchange of the contents of the conversation can post a comment at a desired part in the middle of the conversation or at the end of the conversation.

  As shown in FIG. 23, when the four-dimensional time space of the conversation content to which the comment is posted is accessed, the posted comment data is stored in the hyperlink database 60, and the comment is posted along with the exchange of the conversation content. Comments are also displayed. Further, the link destination URL http: // hij is also displayed. If another person clicks on the link destination URL, the user can jump to and access the corresponding user's content (such as a blog).

  The link source specification control described based on FIGS. 22 and 23 has a relay function that links (bridges) a virtual world (four-dimensional space-time) and a cyber space such as a blog or SNS (Social Networking Service). It is a thing. In addition, the connection target may be anything in the virtual world (four-dimensional space-time), such as the aforementioned community virtual tag, the writing page linked to it, the cyber special zone, each area of the history virtual world described later (see S231), etc. It may be anything. Also, as described later as a modification, when it is possible to search in the virtual world (in four-dimensional space-time), ranking is performed based on the number of links etc. Control may be performed so as to reflect the display order.

  Fig.24 (a) shows the subroutine program of the past virtual world terminal processing shown by S301 of Fig.15 (a), and FIG.24 (b) shows the past virtual world shown by S311 of FIG.15 (b). It is a flowchart which shows the subroutine program of correspondence processing.

  Referring to FIG. 24A, in the past virtual world terminal process, the history virtual world terminal process is executed from S212, and the other terminal processes are executed in S211.

  Referring to FIG. 24B, in the past virtual world terminal process, the historical virtual world correspondence process is executed in S220, and the other correspondence processes are executed in S221.

  The history virtual world terminal process of S210 and the history virtual world correspondence process of S220 are processes for providing a service related to history using a virtual world which is a four-dimensional space-time.

  Other terminal processing of S210 and other corresponding processing of S221 generate a memorial virtual tag at a memorable place and time such as the place where the proposal was made and the time, for example. It is a service such as recording and saving in a page corresponding to a memorial virtual tag. Then, the contents of the page corresponding to a plurality of memorial virtual tags of the user from the time of creation until the present time can be edited in time series and displayed, and the user's own history can be created.

  FIG. 25 (a) is a flowchart showing a subroutine program of the historical virtual world terminal processing shown in S210 of FIG. 24 (a), and FIG. 25 (b) is a historical virtual shown in S220 of FIG. 24 (b). It is a flowchart which shows the subroutine program of a world response process. In the history virtual world terminal processing, it is determined in S230 whether or not there is an access operation to the history virtual world, and if there is not, the subroutine program is terminated. On the other hand, when the user performs an access operation to the historical virtual world by the mobile phone 2, the control proceeds to S231, and a process for accepting an entry operation of each area to the historical virtual world is executed. Each area of the history virtual world has four areas of "History Area", "Hypothesis Area", "Another World Area", and "Information Exchange Area", and the user operates the mobile phone 2 to select one of these four areas. Choose one.

  The "historical area" is an area where you can view detailed data about various times, such as the three-dimensional display of the scene at that time, the flat display function and audio guidance, the age period regarding the history, and the future location.

  A "hypothetical area" is an area that provides information that is contested differently from formal history. For example, source Yoshitsune was active as Genghis Khan without being killed. Provide information such as

  "Another world area" is an area where information can be viewed, such as what happened to the world if this person had not been killed at that time of history.

  "Information exchange area" is an area where users can freely participate in the community and exchange information about their buildings and people in the community set up in the historical virtual world such as the current SNS. is there.

  The "history area" is information provided by the service provider 8 or a service provider specializing in history. In the other “hypothetical area”, “another world area”, and “information exchange area”, basic information is provided by the service provider 8 or a service provider specializing in history, and the user himself / herself takes the initiative in conveying each information and thoughts It is a mechanism that can

  Next, control proceeds to step S232, where a process of transmitting the user ID and the area of the selected historical virtual world to the server 10 is performed.

  In the server 10, the process is received in S238, and in S239, processing is performed to determine whether the user is a user of a pay member based on the received ID. The server 10 stores data for specifying whether the user is a pay member in association with the user ID. When it is determined in S240 that the member is a paid member, display processing of the historical virtual world is executed in S241. On the other hand, if it is determined that the member is a general member who is not a pay member, the control proceeds to S242, and it is determined whether the area selected by the user is a general user display area according to S231. The server 10 is connected to a history virtual database 62 described later based on FIG. Data is stored in the history virtual database 62 so as to distinguish whether it is an area that can be viewed by general users or an area that can be viewed only by paid member users. The server 10 searches this history virtual database 62 to determine whether the selected area is an area for general user display, and if it is an area for general user display, the control is S241. If it is not an area for general user display, that is, if it is an area where only paid members can view, the control proceeds to S243, and it returns to the mobile phone 2 that it can not be displayed because it is not a paid member.

  The mobile phone 2 receives it in S233, and executes a process to display that it can not be displayed because it is not a paid member in S234.

  FIG. 26 (b) is a flow chart showing a subroutine program of the historical virtual world display process shown in S241 of FIG. 25 (b). First, in S258, a process of searching for a history tag near the current position of the user in the area selected in accordance with S231 is performed. Here, the "user's current position" refers to the user's entry position in the virtual world when the user is entering the virtual world, and is real when the user has not entered the virtual world. It is the current position of the user in the world. The "history tag" is a virtual tag displayed in the virtual world and in the real world, and history description data and data for 3D display stored in association with the history tag by being clicked by the user Is a tag for displaying to the user. The title of this history tag is stored in the history virtual database 62 in association with each area information. The history tag is then displayed to the user along with the title.

  Next, control proceeds to S259, where it is determined whether there are multiple history tags in chronological order. That is, it is determined whether there are a plurality of history tags retrieved in S258 in time series near the current position of the user. For example, if the current position of the user is Sekigahara Town, Gifu Prefecture, in the case of FIG. 28, there is a history tag titled “Sekigahara Battle” on the time axis (w = 11/10, October 1600) The history tag will be displayed, but if history tags corresponding to other history areas exist in Sekigahara-cho in the same Gifu prefecture, if it exists on a different time axis w (period), YES by S259 Then, control is passed to S 260, and processing for transmitting the plurality of history tags to the mobile phone 2 is performed.

  In the mobile phone 2, control is performed to receive it at S 245 and display a plurality of received history tags at S 246. Next, in S247, it is determined whether or not the user has selected a history tag, and the process waits until there is one. When there is a selection operation, processing of transmitting the selected history tag to the server 10 is performed by S248. The server 10 receives it in S261. Next, at S262, control is performed to display the received history tag or one history tag retrieved by S258 in the real world or virtual world near the current position of the user.

  On the other hand, in the mobile phone 2, the selected history tag is displayed in S249, and it is determined whether or not there is a click operation on the displayed history tag in S250, and the loop of S249 → S250 → S249 is performed. Go around. When the user clicks a displayed history tag, control is performed to transmit a click signal of the history tag to the server 10 in S251. The server 10 receives it at S263, and at S264, control is performed to specify history explaining data and 3D display data corresponding to the clicked history tag and transmit it to the mobile phone 2. Specifically, the server 10 searches the history virtual database 62 of FIG. 28 and the history explanation data 3D stored corresponding to the history area stored corresponding to the title of the clicked history tag. The display data is retrieved and the retrieved data is transmitted to the mobile phone 2. Specifically, when a history tag titled Sekigahara's battle is clicked, historical explanation data "3D display data and 3D display data", which is stored in association with it, is "the battle that determined the supremacy of Ieyasu Tokugawa" Is identified and the data is sent to the mobile phone 2.

  Depending on the mobile phone 2, it is received at S 252, and at S 253, control is performed to display the received history explanation data and 3D display data. Next, in S254, it is determined whether or not the switching operation has been performed on other history tags in the plurality of history tags present in time series, and if not, control proceeds to S270, but the switching operation is performed If so, the control returns to S246, and an operation of displaying a plurality of history tags existing in chronological order again and selecting a history tag from among them is performed. This makes it possible to reselect another history tag among the plurality of history tags present in chronological order and display and browse the corresponding history explanation data and 3D display data.

  On the other hand, when the determination in S254 is NO, it is determined in S270 whether or not the switching operation of the entry area has been performed. If not, the control proceeds to S271. However, when the user operates the mobile phone 2 to switch the entry / exit area, the control returns to S231, and the area to be entered again is selected again from the four areas. Control is performed.

  If NO is determined in S270, it is determined in S271 whether a write operation has been performed in the page of the area. If not, the control proceeds to S273, but if the user operates the mobile phone 2 to perform the writing operation, the control proceeds to S272, and control is performed to transmit the written data to the server 10.

  In the server 10, control is made to receive it and store the written data in the historical virtual database 62 in S277. For example, as another world information "If the West Army was victorious, what happened to Japan after that?" As the hypothesis information "The map of the treasure of Ieyasu Tokugawa was stolen when the castle tower was lost in the southwest war The user writes data such as “...” and the written data is written and stored in the historical virtual database 62.

  On the other hand, when the user operates the mobile phone 2 to perform the termination operation (S273), the termination operation signal is transmitted to the server 10, is received by S279, and termination processing is executed in S280.

  FIG. 29 (a) shows a subroutine program of the future virtual world terminal process shown in S302 of FIG. 15, and FIG. 29 (b) shows a subroutine program of the future virtual world correspondence process shown in S312 of FIG. There is.

  First, in the future virtual world terminal process, the weather forecasting terminal process is executed in S700, the future dating terminal process is executed in S701, and the future schedule terminal process is executed in S702.

  In the future virtual world correspondence processing, the weather forecast correspondence processing is executed in S705, the future dating correspondence processing is executed in S706, and the future schedule correspondence processing is executed in S707.

  The weather forecasting terminal processing and the weather forecasting processing are to display the virtual world according to the past present weather and the future weather forecast. For example, when the current weather condition of Tokyo is rain, when the user enters the virtual world and accesses the current Tokyo, a landscape of rain is displayed.

  The future schedule terminal process and the future schedule correspondence process are for displaying the avatar of the user in the future virtual world based on the schedule of the user described based on FIG. For example, referring to FIG. 14, when the user ID is 13B9 PS, it is a schedule for participating in the イ ベ ン ト event as a future schedule. If this ○ event is to be held at Shibuya Dogenzaka from 1 to 3 pm tomorrow, the avatar (agent) of the user of 13B 9 PS will continue at Shibuya Dougensaka from 1 to 3 pm tomorrow in the virtual world Will be displayed.

  This detailed control will be described based on FIG. FIG. 30 is a flowchart showing a subroutine program of the future schedule terminal process shown in S700 and the future schedule handling process shown in S707. In the mobile phone 2 of the user, it is first determined at S710 whether or not there is a schedule input operation, and if it is not, it is determined at S714 whether or not a future virtual world display operation is performed. The subroutine program ends.

  If the user operates mobile phone 2 to perform a schedule input operation, YES is determined in S710 and control proceeds to S711, and the input schedule including time and place is stored by, for example, EEPROM 42 in mobile phone 2 Processing is performed. Next, in S712, it is determined whether or not the notification to the server 10 is to be performed, and if the notification to the server 10 is not to be performed, the process proceeds to S714. On the other hand, if the user performs an operation of notifying the server using the mobile phone 2, the control proceeds to S713, and processing of transmitting the schedule including the input time and place and the user ID to the server 10 is performed. In response to this, in S720, the server 10 associates the schedule including the received time and place with the user ID and stores the schedule in the user four-dimensional coordinate database 11a.

  On the other hand, if the user performs a future virtual world display operation by using the mobile phone 2, a determination of YES is made in S714, and the process proceeds to S715 to transmit the user ID, the access position, and the future access date to the server 10. . The user operates the mobile phone 2 to input a position (place) to be accessed in the future virtual world and a future date and time to access, and the input data is transmitted to the server 10 by S715.

  In response to this, the server 10 executes the processes of S34 to S37 shown in FIG. 9 and then searches the user four-dimensional coordinate database 11a in S722 to search for the received access position in the vicinity of the received access position. The avatar (agent) that is scheduled to be at the date and time is identified and overlaid on virtual world 3D data and displayed. Next, the processes of S39 to S42 (see FIG. 9) are performed.

  FIG. 31 is a flowchart showing a subroutine program of virtual world display correspondence processing shown in S331 of FIG. First, the server 10 executes the processing of the same steps as S30 to S32 shown in FIG. 9, and it is judged at S480 whether the user's ID, access position and access time have been transmitted from the mobile phone 2 or not. Ru. When the access position of the virtual world that the user wants to access, the access time, and his user ID are transmitted from the mobile phone 2 to the server 10, YES is determined in S480, and the same processing as S34 and S35 in FIG. Is performed, and then the same process as S36 is performed, and then the same process as S37 is performed. Next, the process proceeds to S481, the user four-dimensional coordinate database 11a is searched, users near the access time (w) and the access position (x, y, z) are identified, and conversation data with the agent (avatar) is virtualized. A process of overlaying and displaying on world 3D data is performed. The conversation data is stored in a conversation database 61, which will be described later based on FIG. 32, and indicates the conversation contents of the users via the agent (avatar) in the virtual world or the conversation of the agent (avatar) itself. It is the content.

  Next, the control proceeds to S 482, where it is determined whether the link destination URL is attached to the displayed virtual world. The link destination URL is the link destination URL stored in the hyperlink database 60 described with reference to FIG.

  When the link destination URL is not attached, the same process as the process shown in S39 to S42 of FIG. 9 is executed. On the other hand, when the link destination URL is attached, the control proceeds to S483, and control is performed to display the link destination URL in the virtual world. Next, in S484, it is determined whether there is a comment input. If not, the processing of S39 to S42 is executed. If there is a comment, the input comment is used as the hyperlink database 60 in S485. After the control of storing in (see FIG. 23) and displaying the comment in the virtual world is performed, the processing of S39 to S42 is executed.

  Next, in S486, it is determined whether there is a request for advancing time in the accessed virtual world. If the user accessing the virtual world is accessing the current virtual world, the time progresses in the virtual world as time progresses in the real world, and the situation of avatar (agent) movement is displayed. If the user designates and accesses the virtual world of the past or the virtual world of the future, the virtual world with the time axis w fixed at the designated time (w) is displayed. Become. When the user moves in the virtual world at that time and wants to advance the time at a certain place, the user operates the mobile phone 2 to request the progress of the time, and transmits it to the server 10. Then, a determination of YES is made at S486, and the process proceeds to S487, where control for advancing time w is performed, and the control returns to S36.

  The progress control (step control) of time w in this S487 is to advance the virtual world at the same progress speed as the normal time progress speed in the real world, but it is faster or slower than the real world. It is also possible for the user to freely select the traveling speed and request the server 10, such as the speed. In the server 10, the time w is step-controlled by S487 in accordance with the requested traveling speed. Also, control may be made to reversely advance the time axis w in the reverse direction at a designated speed.

  On the other hand, when the determination of NO is made in S486, the control proceeds to S488, and it is determined whether or not there is a slide request for the access position in the virtual world. When the user operates the mobile phone 2 to slide the access position of the currently accessed virtual world and move it, the slide request signal is transmitted to the server 10, and the determination of YES is made in S488. Then, in S489, control is performed to slide the three-dimensional coordinates (x, y, z) in the virtual world to move the access position. Thereafter, control returns to S36. FIG. 32 is a view for explaining data stored in conversation database 61. Referring to FIG. The conversation database 61 is installed in the service provider 8, and the server 10 can write and read data.

  The conversation database 60 stores location data and conversation data in the virtual world in which the conversation was conducted in association with the user ID and the user ID. The position data and the conversation data in the virtual world change according to the time axis w, and the position data and the conversation data in the virtual world at that time are stored in the speech database 61 according to the change of the time axis w. It is done. That is, in the conversation database 61, conversation data is stored in the form of four-dimensional coordinate data, similarly to the user four-dimensional coordinate database 11a shown in FIG. However, w, x, y, and z fluctuate with the movement of each user as each user enters a virtual world which is a four-dimensional space-time, and performs a conversation while moving a place and moving an entry time (age). The four-dimensional coordinates (w, x, y, z) in conversation also vary depending on the user. Such variation data is stored as four-dimensional coordinate data in association with each user ID. That is, since each user has a different entry location, entry time (age) and movement mode, the time axis w is also set for each user (for each user ID). That is, the time axis w is set as many as the number of users (user IDs).

  FIG. 33 is a flowchart showing a subroutine program of the authentication terminal process shown in S303 of FIG. 15 and the authentication process shown in S313. As the authentication terminal process, it is determined in S800 whether or not an authentication request operation has been performed. If the user operates the mobile phone 2 to perform an authentication request operation, a determination of YES is made in S800, the control proceeds to S801, and it is determined whether it is an operation of a request for SSL (Secure Socket Layer) authentication. Ru. In the case of the normal SSL authentication request, the normal SSL authentication request process is executed in S802, and the server 10 receives the request and executes the normal SSL authentication process in S805.

  On the other hand, when the user operates the mobile phone 2 to operate the four-dimensional coordinate authentication request, a determination of NO is made in S801, the control proceeds to S803, and the four-dimensional coordinate authentication request process is executed. In response to this, the server 10 executes four-dimensional coordinate authentication processing in S806.

  FIG. 34 is a flowchart showing a subroutine program of the four-dimensional coordinate request process shown in S803. By S803, the authentication menu is displayed by the mobile phone 2 of the user. The menu items displayed by this authentication menu display are "contract authentication item", "four-dimensional coordinate electronic certificate item", and "other authentication item". When the user purchases a product or the like and makes a contract such as installment payment, the “contract authentication item” is selected. If you want to issue an electronic certificate to prove that the user is at a certain place (on a certain four-dimensional coordinate) at a certain time, select "four-dimensional coordinate electronic certificate item" .

  When the user operates the mobile phone 2 to select the contract authentication item, the control proceeds to S 835 and the contract authentication request processing is executed. When the user operates the mobile phone 2 to select the four-dimensional coordinate electronic certificate item, the control proceeds to S836, and the four-dimensional coordinate electronic certificate issuance request process is executed. If the user has selected another item, control proceeds to S834, where other authentication request processing is performed.

  The four-dimensional coordinate authentication process on the side of the server 10 shown in S806 described above also includes a subroutine program of contract authentication process corresponding to S835, and four-dimensional coordinate electronic certificate issuance process corresponding to S836.

  FIG. 35 is a flow chart showing a subroutine program of contract authentication request processing shown in S 835 and contract authentication processing on the server 10 side corresponding thereto. In the contract authentication request processing, the mobile phones 2 of both the contracting party, ie, the obligor A and the creditor B jointly request the server 10 to generate a shared virtual tag for contract, and the contract authentication in the server 10 The process generates a contract shared virtual tag. When the debtor A purchases digital content such as pay video content, DRM (Digital Rights Management) processing is also executed.

  First, in S860, the debtor A's mobile phone 2 reads out the shared virtual tag ID from the EEPROM 42. Next, in S861, processing for generating a variable shared virtual tag ID is performed using GPS time information. This process is the same as the process described based on S2 of FIG. 7, and the description thereof will not be repeated here. Next, in S862, processing for transmitting the variable shared virtual tag ID to the mobile phone 2 of the creditor B using infrared communication or the like is performed.

  In the mobile phone 2 of the creditor B, in S863, a determination is made as to whether or not to access the server 10. If the obligor B operates the mobile phone 2 to input an operation to access the server 10, a determination of YES is made in S863, and the user ID of the obligor B (user ID stored in the EEPROM 42) is determined in S864. A process of transmitting the contained user authentication data to the server 10 is performed. In the server 10 having received it, in S869, the identity is confirmed, and in S870, the access permission is returned to the debtor B's mobile phone 2. The processes of S864 to S870 are the same as the processes of S5 to S7 in FIG. 7, and the detailed description will not be repeated here.

  Next, the mobile phone 2 of the obligor B performs an operation to generate a shared virtual tag for contract in S865, and according to the operation, the current position data of the mobile phone 2 of the creditor B and the debtor A in S866. The variable shared virtual tag ID and the contractor data are transmitted to the server 10, and processing for requesting generation of a contract shared virtual tag is performed.

  In the server 10 having received it, the processes of S15, S16, S20 to S24, S16a to S16a, and S17 to S19 described based on FIG. 8 are performed. However, the “shared virtual tag” in the processing of each step described based on FIG. 8 is “a shared shared virtual tag for contract” in FIG.

  Next, in S871, processing is performed to store data of the contract document and data of the payment page displayed on the page of the contract shared virtual tag. As a result, when the debtor A or the creditor B operates the mobile phone 2 to access and click on the contract shared virtual tag generated in the virtual world, the page of the shared shared virtual tag for the contract is displayed. It is displayed, the contract written between the obligor A and the creditor B is displayed on the page, and the page of payment in installments etc. is also displayed. The obligor A can access the payment page and follow the payment page to make payment (payment of debt) by credit card etc.

  Next, as described above, in the case of buying and selling digital content, the DRM request processing is performed in S868 in the mobile phone 2 of the creditor B, and the DRM processing is performed in S872 in the server 10 that has received the request. Be done. These processes will be described later based on FIG.

  As a result of the DRM processing to be described later, the encrypted digital content is sent back to the mobile phone 2 of the creditor B from the server 10, and the mobile phone 2 of the creditor B receives the encrypted digital contents in S873. Is transmitted to the debtor A's mobile phone 2.

  FIG. 36 is a flowchart showing a subroutine program of the DRM request processing shown in S868 and the DRM processing shown in S872. In the DRM processing, processing of transmitting digital content to the server 10 is first performed in S820. The server 10 receives the digital content at S823. In addition, in the mobile phone 2 of the creditor B, the data for designating the digital content purchaser (the debtor A) is transmitted to the server 10 in S821. The designation data of the digital content purchaser is, for example, the variable shared virtual tag ID of the mobile phone 2 of the debtor A or the like. In the server 10 having received it, processing of randomly determining four-dimensional coordinate data to be used for DRM from among the designated four-dimensional coordinate data (see FIG. 14) of the purchaser is performed by the random number R1 in S824. As a specific example of the process of S824, for example, appropriate four-dimensional coordinate data is extracted from the user four-dimensional coordinate database 11a while the mobile phone 2 of the designated purchaser, ie, the obligor A is moving. The extracted data is data in which coordinate data of x, y and z change in accordance with the change of time w. This is because the buyer (debtor A) is moving. The random number R1 is generated by the server 10 within the range in which the time w in the extraction data from the user four-dimensional coordinate database 11a changes. Then, the coordinates (w, x, y, z; w = R1) obtained by substituting the random number R1 into the time w in the user four-dimensional coordinate database 11a are determined as four-dimensional coordinate data used for DRM.

  Then, in S825, processing is performed to encrypt digital content using the determined four-dimensional coordinate data as the key K1. Next, in S826, the random number R1 is embedded in the encrypted digital content as a digital watermark. Next, in S827, the encrypted digital content is sent back to the mobile phone 2 of the creditor B. In the mobile phone 2 of the creditor B, a process of receiving the encrypted digital content is performed in S822.

  In FIG. 37, the contents reproduction process on the mobile phone 2 side and the reproduction authentication process on the server 10 side, which are used when reproducing the digital contents purchased by the obligor A, that is, the encrypted digital contents transmitted according to S873. It is a flowchart which shows the objective control content. First, at S 880, in the mobile phone 2, it is determined whether or not the reproduction operation has been performed. If the purchaser (debtor A) operates the mobile phone 2 to perform a content reproduction operation, YES is determined in S880, and in S881, a process of extracting the random number R1 from the encrypted content is performed. This is a process of extracting a random number R1 embedded in the encrypted content as a digital watermark. Then, in S882, a process of transmitting the user ID and the extracted random number R1 to the server 10 is performed.

  The server 10 receives it (S890), and in S891 determines the four-dimensional coordinate data to be used for the key K1 from among the received four-dimensional coordinate data (see FIG. 14) using R1. To be done. Specifically, the four-dimensional coordinate data of the user consisting of data of the current position corresponding to the received user ID and data of the time w is specified, and the random number R1 is substituted for the time w. Four-dimensional coordinate data (w, x, y, z; w = R1) is determined.

  Next, in S892, processing of randomly determining four-dimensional coordinate data to be used for DRM from among the four-dimensional coordinate data of the user ID is performed using the random number R2. The process of S892 is the same as the process of S824 described above, and the detailed description will not be repeated here. Next, in S893, the determined four-dimensional coordinate data is set as the key K2, and the key K2 and the key K1 determined in S891 and the random number R2 are transmitted to the mobile phone 2.

  The mobile phone 2 receives it (S883), and uses the received key K1 to decrypt and reproduce the encrypted content. Next, in S885, the process of encrypting the content which has been reproduced is performed using the key K2, and in S886, the process of embedding the random number R2 in the encrypted content as a digital watermark is performed. Then, the mobile phone 2 overwrites and stores the new encrypted content in which the random number R2 is embedded. As a result, the old encrypted content in which R1 is embedded is erased, and a new encrypted content in which R2 is embedded is stored. Thus, each time the encrypted content is reproduced, the key and the random number are updated as key K2 → key K3 → key K4 ..., R2 → R3 → R4 ... and a new random number is embedded. New encrypted content is overwritten and saved.

  FIG. 38 is a flowchart showing a subroutine program of the four-dimensional coordinate electronic certificate issuance request processing shown at S 836 in FIG. 34 and the corresponding four-dimensional coordinate electronic certificate issuance processing in the server 10. First, the personal identification data including the user ID is transmitted in S 840 in the mobile phone 2, and the server 10 receiving it transmits an identity confirmation in S 842 to the mobile phone 2 in S 842. The processes of S840 to S842 are the same as the processes of S5 to S7 shown in FIG. 7, and thus the detailed description will not be repeated here.

  The mobile phone 2 having received the access permission receives the designation operation (designation of the time w, designation of the latitude x and the longitude y, etc.) of the four-dimensional coordinates desired to be certified in S843. Next, in step S844, the designated four-dimensional coordinate and four-dimensional coordinate electronic certificate issuance request request are transmitted to the server 10. The server 10 that has received it determines in S845 whether or not the principal is present in the designated four-dimensional coordinates, and if it is determined in S846 that there is no principal, the proof refusal due to the absence is transmitted to the mobile phone Processing to reply to 2 is performed. On the other hand, if it is determined in S846 that there is a digital signature attached to the four-dimensional coordinate data of the person determined to exist in S847, a process of creating an electronic certificate is performed. This digital signature is a digital signature by the service provider 8 in which the server 10 is installed. Specifically, using the private key of the service provider 8, the four-dimensional coordinate data and the 'user four-dimensional coordinate database are certainly present And the like, and use the decrypted data as a digital signature. Then, the electronic certificate is transmitted to the mobile phone 2 at S848.

  The portable telephone 2 stores the transmitted electronic certificate in the EEPROM 42 or the like for storage. Then, when it is necessary to prove that the person is present in the four-dimensional coordinates certified by the electronic certificate, the stored electronic certificate is read out from the EEPROM 42 and presented. For example, if you acquire a credit by proving that you attended a certain class at a university, or if you encounter a certain case in the real world, write a blog about the case and the location of the case at the time of the occurrence of the case It is conceivable to use an electronic certificate to prove that it is present in the blog.

  In the control related to the authentication in FIG. 33 to FIG. 38 described above, in order to perform not only terminal authentication but also user identity authentication, identity authentication between the mobile phone 2 and the user who is the owner is first performed. Need to be done. For example, a password or a personal identification number may be input to the mobile phone 2 to perform personal authentication, or a fingerprint of a user may be read by the mobile phone 2 to perform biometric authentication.

  Further, the access control to the shared virtual tag for contract may be the same as the access control to the shared virtual tag described in the first embodiment, but the following control may be used. First, data (w, x, y, z) consisting of the place where the obligor A and the obligee B made a contract (= the place where the shared virtual tag for contract is generated) and the time is stored in the server . Next, the server 10 is requested to transmit a user ID from the mobile phone 2 of the user who accessed by clicking on the contract shared virtual tag, and the server 10 searches the user four-dimensional database 11a and associates it with the user ID The four-dimensional coordinate data of the user stored in memory is determined, and it is determined whether the user has contracted at a place and time (w, x, y, z), and the condition is that access is Tolerate.

  In the control related to authentication in FIGS. 33 to 38, authentication is possible while keeping personal identification information such as a user's address and name or an e-mail address confidential, and specific authentication can be performed while protecting user privacy. There is an advantage. Conventionally, as authentication technology having such an advantage, anonymous authentication or attribute authentication has been known, but there has been a drawback that it can not be realized unless advanced encryption technology such as group signature is used. However, in the case of the authentication technology shown in FIGS. 33 to 38, there is an advantage that it is not necessary to make full use of advanced encryption technology, and the same effect as anonymous authentication or attribute authentication can be realized by a simple method.

  39 (a) shows a subroutine program of virtual world advertisement terminal processing shown in S304 of FIG. 15 (a), and FIG. 39 (b) shows a virtual world advertisement shown in S314 of FIG. 15 (b). It is a flowchart which shows the subroutine program of correspondence processing.

  In the virtual world advertising terminal process, an advertising display terminal process is performed in S500. This advertisement display terminal process is a process for displaying an advertisement display prepared in the virtual world on the mobile phone 2.

  On the other hand, in virtual world advertisement correspondence processing, display advertisement setting correspondence processing is performed in S503, and advertisement display correspondence processing is executed in S504. The display advertisement setting process in S503 is a process for receiving an advertisement setting operation for displaying in the virtual world by an advertiser client described later, and setting and storing an advertisement that the advertiser wants to display in the virtual world. The advertisement display support process of S504 is a process of the server side 10 corresponding to the advertisement display terminal process of S500, and is a process for transmitting an advertisement prepared in the virtual world to the mobile phone 2 for display.

  FIG. 39 (c) is a flow chart showing a subroutine program of display advertisement setting operation processing executed by the advertiser client, and FIG. 39 (d) shows a subroutine program of display advertisement setting handling processing shown in S503. It is a flowchart.

  In the advertiser client, when the login operation to the advertisement menu is performed in S510, control for transmitting authentication data of the advertiser client to the server 10 is performed in S511. The server 10 receives it in S515, and in S516, based on the authentication data, the advertiser client is not impersonated, etc., but has been able to confirm the identity authentication as to whether or not it is a proper legitimate advertiser client. Above, control is performed to send advertising menu data to the advertiser client. The advertiser client receives it in S512, and performs an advertisement menu selection input process in S513. Through the advertisement menu selection input process, the server 10 receives the transmitted data, and the input menu registration process is executed in S517.

  FIG. 40A, FIG. 41, and FIG. 42 are flowcharts showing a subroutine program of the advertisement menu selection input process shown in S513, and FIG. 40B shows a subroutine of the input menu registration process shown in S517. It is a flowchart which shows a program. As the type of input menu, display method menu of advertisement (S520), display distance menu (S523), display time menu (S526), advertisement type menu (S535), display category menu in virtual world (S538), virtual There are eight types of display classification menus for users in the world (S541), menu display when there are mutual functions (S546), and a display area selection menu (S549).

  First, in S520, a menu regarding how to display an advertisement is displayed on the advertiser client. There are three display methods: constant display type, pop up type, and selective type advertisement. These three types of menu items are displayed. The always-on type is an advertisement that is always displayed regardless of whether the advertisement is updated. In the pop-up type, when an advertisement is updated, a pop-up display to that effect is made and the newly updated advertisement is displayed. The selective advertisement is for displaying an advertisement matching the user or an advertisement selected by the user from among a plurality of types of advertisements.

  In S521, it is determined whether or not a menu item selection operation has been performed. If not, the display processing of S520 is performed. If the user performs a selection operation with the mobile phone 2, a determination of YES is made in S521, the control proceeds to S522, and processing for transmitting the selected menu item to the server 10 is performed. The server 10 receives the data in S530, and registers the received data in the virtual world advertisement database 63 (see FIG. 43). Next, in S532, it is determined whether all registration of the advertisement menu has been completed, and if not completed, the process returns to S530, and the loop of S530 → S531 → S532 → S530 is circulated.

  On the other hand, in the advertiser client, control to display a menu item of the display distance of the advertisement to the user who has entered the virtual world is performed in S523. Specifically, three types of distance type, middle distance type and short distance type are prepared as the display distance menu. The advertiser client determines whether or not the selection operation of the display distance menu item has been performed in S524. If there is not, the display processing of S523 is continuously performed. When there is a selection operation, the control proceeds to S525, and processing for transmitting the selected menu item to the server 10 is performed. In the server 10, control is performed to receive the data in S530 and to register the received data in the virtual world advertisement database 63 in S531.

  Next, in the advertiser client, control to display a menu item of display time is performed in S526. Specifically, items of constant display and time limited display are displayed. The constant display is an advertisement that is always displayed for 24 hours, and the time limited display is an advertisement that is displayed by limiting a predetermined time such as only during the daytime or only during the nighttime. Whether or not the selection operation has been made is determined in S527, and the display processing of S526 is continued until there is a selection operation. If there is a selection operation by the advertiser client, the selected item is transmitted to the server 10 at S528. The server 10 receives it at S530, and controls to register the received data in the virtual world advertisement database 63.

  The advertiser client is further controlled in S535 to display an advertisement type menu. There are three types of advertisements: audio-only advertisements, video and image-only advertisements, and audio + video and image advertisements. In S536, it is determined whether or not the selection operation has been performed, and if there is no selection operation, the display control of S535 is continued. If there is a selection operation by the advertiser client, processing of transmitting the selected menu item to the server 10 is performed in S537. The server 10 receives it at S530, and controls to register the received data in the virtual world advertisement database 63 at S532.

  In the advertiser client, further, in S538, a menu is displayed that represents the display category of the advertisement in the virtual world. Specifically, there are three types of advertisement display categories: advertisements that are displayed only in the current world, advertisements that are displayed only in the past world, and advertisements that are displayed in all ages, including the future. If it is not determined in S539 whether or not the menu item selection operation has been performed, the display in S538 is continued. If there is a selection operation by the advertiser client, the selected item is transmitted to the server 10 in S540. The server 10 receives the data in S530, and registers the received data in the virtual world advertisement database 63 in S531.

  In the advertiser client, in S541, a menu is displayed to indicate the display classification to the user in the virtual world. Specifically, four display categories are displayed: advertisements displayed for all users, advertisements displayed only for limited users, advertisements displayed only for terminal users, and advertisements displayed only for Web users. ing. The limited user may be, for example, a user who has registered a pay member. Whether or not the selection operation has been made is determined in S542, and if it is not operated, the display control of S541 is continued. If there is a selection operation by the advertiser client, control is performed to transmit the selected menu item to the server 10 in S543. The server 10 receives the data in S530, and registers the received data in the virtual world advertisement database 63 in S531.

  In the advertiser client, in step S546, a menu is displayed when the advertisement has a mutual function. Specifically, there are three types: inquiry function type, word-of-mouth function type, and street sales function type. The query function type is an advertisement that allows the user to ask the advertiser. The word-of-mouth function type is an advertisement that allows a user to read a word-of-mouth that has already been written and to write a word-of-mouth newly for a product or the like to be advertised. The street selling function type is an advertisement that allows the advertiser to display a store at the user's entry position in the virtual world and sell the product there when the user who has seen the advertisement wants to purchase the product to be advertised.

  In S547, it is determined whether or not the selection operation has been performed. If not, the display control of S546 is continued. If there is a selection operation by the advertiser client, processing of transmitting the selected item to the server 10 is performed in S548. The server 10 receives the data in S530, and registers the received data in the virtual world advertisement database 63 in S531.

  In the advertiser client, further, at S549, the selection menu of the area for displaying the advertisement is displayed. Specifically, three types are provided: global display, national display, and regional display. It is judged at S550 whether there is a selection operation or not. When there is a selection operation at S551, the country name to be displayed is selected in the case of 2 selection, ie in the case of national display selection, and in the case of 3 selection In the case of area limited display, control for selecting and inputting the area to be displayed is performed. In the case of the advertisement at the time of area limited display, for example, the advertisement specific to the area rooted in the area where the advertisement is displayed is displayed. For example, in the case of the advertisement display limited to Nishijin of Kyoto, advertisements such as a store of Nishijin Ori are displayed. Further, in the case of an advertisement limited to the location of the store in the virtual world corresponding to a certain store, the advertisement of the product or service content of the store is carried out.

  Next, in S550, it is judged whether or not there is a selection operation, and if there is a selection operation, in S551, the country name to be displayed is selected in case of 2 selection, that is, in the case of national display, and in case of 3 selection, ie region In the case of limited display, control for selecting and inputting a display target area is performed. Next, control to transmit the selected item to the server 10 is performed in S552. The server 10 receives the data in S530, and controls the received data to be registered in the virtual world advertisement database 63 in S531.

  Next, in the advertiser client, in S553, it is determined whether or not there is an input operation of the advertisement content and the comment information. As the advertisement content, for example, referring to FIG. 43, which is a display representing the advertisement content of an ○ glasses store, ○ product building, etc. As comment information, during sales, business hours are 9 am to 9 pm Please do not hesitate to consult with us until installation installation. And so on. When there is an input operation of the advertisement content and the comment information, the control proceeds to S554, and processing of transmitting the input information to the server 10 is performed. The server 10 receives the data in S530, and registers the received data in the virtual world advertisement database 63 in S531.

  FIG. 43 is a diagram showing information stored in the virtual world advertisement database 63 connected to the server 10. The virtual world advertisement database 63 stores various types of information as described in S520 to S553, but only representative ones are shown in FIG.

  FIG. 44 (a) is a flowchart showing a subroutine program of the advertisement display terminal process shown in S500, and FIG. 44 (b) is a flowchart showing a subroutine program of the advertisement display handling process shown in S504. As the advertisement display terminal processing, it is determined in S558 whether the user is logging in to the virtual world by the mobile phone 2 or not. If the user is not logging in, this subroutine program ends. When the user is logging in, the server 10 performs control to display an advertisement shown to the user who is logging in at S570. Specifically, the server 10 searches the virtual world advertisement database 63 and selects an advertisement to be displayed to the user from among the advertisements stored in the virtual world advertisement database 63. Next, in S571, a signal for overlaying the selected advertisement on the virtual world and displaying it on the user's mobile phone 2 is transmitted. The mobile phone 2 receives it in S559, and controls in S560 to overlay and display the received advertisement. Next, in S561, it is determined whether the user has performed an operation to gaze at the advertisement. This is, for example, an operation to be displayed at the center of the screen to zoom map the advertisement. If there is an operation to gaze at the advertisement, control to notify the server 10 of the advertisement targeted for the gaze is performed in S562. The server 10 receives it by S572, and searches the virtual world advertisement database 63 for detailed information such as advertisement contents and comment information about the notified advertisement by S573, and transmits it to the mobile phone 2 Control is performed. The mobile phone 2 receives it in S563, and performs overlay display of the received detailed information in S564.

  Next, in S565, it is determined whether or not there is a selection operation according to the type of advertisement. If an operation has been performed, then the control proceeds to S577, where it is determined whether it is a click operation at the link destination of the advertisement. In the normal advertisement, a URL specifying an inquiry destination to the advertiser is embedded as a hyperlink. If the URL of the link destination is clicked, it will move to the homepage of the advertiser by S578.

  On the other hand, if it is not the click of the link destination of the advertisement, it is judged at S579 whether or not it is the selection of the word-of-mouth function. In the case of the word-of-mouth type advertisement described in S546, an operation for selecting the word-of-mouth function is possible. When the user clicks the display portion of the word-of-mouth function, YES is determined in S579, and in S580, the notification that the word-of-mouth selection is made is transmitted to the server 10. The server 10 receives it in S594 and transmits the written word-of-mouth information to the mobile phone 2 in S595.

  The portable telephone 2 receives it in S581 and performs control to display the received written reception information in S582. Next, in S583, it is determined whether a word-of-mouth writing operation is performed. If the user performs an operation of writing a word-of-mouth with the mobile phone 2, the writing information is transmitted to the server 10 in S584. In the server 10, the process is received in S586, and in S597, a process of storing the information in the virtual world advertisement database 63 as the written word-of-mouth information is performed.

  In the mobile phone 2, when it is determined that the selection of the word-of-mouth function is not made in S579, it is determined in S585 whether or not there is an inquiry operation. If not, the process proceeds to S602, but if there is an inquiry operation, the process of transmitting the inquiry signal to the server 10 is performed in S586. The server 10 receives the request in S598, and transmits an inquiry field to the mobile phone 2 in S599.

  The cellular phone 2 receives the inquiry section at S587, displays the received inquiry section at S588, writes the inquiry regarding the advertisement to the inquiry section at S589, and the URL of the advertiser embedded in the inquiry section. Accept the operation to click. Next, in S590, the user is moved to the advertiser's page, and the written inquiry is notified to the advertiser. Then, after waiting for the response of the advertiser, when the response of the advertiser is received, control is performed to display the received response of the advertiser.

  If it is determined in S585 that the operation is not an inquiry operation, the remaining one of the choices for the type of advertisement (see S565) is only the street sales function (see S546). Therefore, the mobile phone 2 transmits a street sales request to the server 10 at S602. The server 10 receives it at S609, and transmits a signal indicating the street sales store to the mobile phone 2 at S610. In the mobile phone 2, it is received by S 603, and control is performed to overlay and display the store for street sales on the virtual world by S 604. On the other hand, after transmitting the display control signal of the store for street sales to the mobile phone 2, the server 10 transmits to the advertiser server that the request for street sales has been made in S611. The advertiser server receives it in S616, and performs customer response processing in the store in S617. The signal of the customer handling process is relayed at S612 and transmitted to the mobile phone 2. The mobile phone 2 can perform an operation of exchange with the store clerk at S605. The signal of the exchange with the store clerk and the customer handling process of S617 by the advertiser server is relayed and exchanged by this mobile phone 2 through S612.

  Next, when a product purchase operation is performed by the mobile phone 2 (S606), the purchase operation signal is relayed to S613 and transmitted to the advertiser server, and the advertiser server performs the settlement process in S618.

  FIG. 47 (a) is a flowchart showing a subroutine program of the marketing terminal process shown in S305 of FIG. 15 (a), and FIG. 47 (b) shows the marketing corresponding process shown in S315 of FIG. 15 (b). It is a flowchart which shows a subroutine program.

  As the marketing terminal process, the questionnaire terminal process is executed in S900, and the settlement operation process is executed in S901. The questionnaire terminal process is a process in which the user answers the questionnaire, and the settlement operation process is a process in which the user uses the mobile phone 2 to perform a settlement operation for the purchased product or the like.

  As the marketing support process, a virtual world store acceptance process is executed in S905, a settlement data collection process is executed in S906, and a marketing data provision process is executed in S907. The virtual world store acceptance process is a process for accepting a store store's request to store in the virtual world through the client of the store merchant. In the settlement data collection process, when the user purchases a product etc. in the virtual world, the settlement organization collects the settlement data, and transmits the settlement data collected by the settlement organization to the server 10 and the server 10 Processing for collecting and storing. The marketing data provision process is a process for providing the collected marketing data to a store outlet or the like.

  FIG. 47 (c) is a flow chart showing a subroutine program showing a shop opening request process by a shop opening trader client (not shown), and FIG. 47 (d) is a flow chart showing a subroutine program of virtual world shop acceptance processing shown in S905. It is. In the shopkeeper client, a shop opening request is transmitted to the server 10 in S910. The server 10 receives the request in step S917, and transmits the shop opening application page to the shop vendor client in step S918. The shopkeeper client receives it in S911, and in S912, the address, the trader name, the shop opening location, and the presence or absence of a questionnaire are entered in the received shop opening application page, and a process of returning to the server 10 is performed. The server 10 receives it in S919, and in S920 a determination is made as to whether there is a questionnaire. This determination is made on the basis of whether or not the data received in S919 is filled with "Questionnaire available". If it is determined that there is a questionnaire, control is performed to transmit the questionnaire page to the store merchant client in S921. The store contractor client receives the request according to S913, and according to S914, control is performed to fill in the questionnaire question items on the received questionnaire page and return it to the server 10. The server 10 receives it in S922, and in S923, performs a shop opening process based on the received content.

  FIG. 48 (a) is a flowchart showing a subroutine program of the questionnaire terminal process shown in S900, and FIG. 48 (b) is a flowchart showing a subroutine program of shop opening processing based on the received content shown in S923. In the server 10, processing for registering the received content in the marketing database 64 (see FIG. 50) is performed in S934. The received content is the content received in S919 and the content received in S922.

  Referring to FIG. 50, marketing database 64 is connected to server 10, and stores user ID, user gender, four-dimensional coordinate data, questionnaire information, settlement information, and the like. User gender that is the gender of the user in association with the user ID, latitude x, longitude y, altitude (above sea level) z, approach in the virtual world when the user enters the virtual world using the mobile phone 2 Four-dimensional coordinate data consisting of a time (time) w, questionnaire information on which the user answered the questionnaire, and settlement information are stored.

  When each user enters a virtual world which is a four-dimensional space-time, and moves a place and moves an entry time (age), w, x, y, z fluctuate with the movement. Such variation data is stored as four-dimensional coordinate data in association with each user ID. That is, since each user has a different entry location, entry time (age) and movement mode, the time axis w is also set for each user (for each user ID). That is, the time axis w is set as many as the number of users (user IDs).

  Further, the settlement information includes the settlement NO, the settlement type, the product, the amount, the store information, and the like. As the payment type, the type of payment used by the user such as credit payment or cash payment (use of a point card) is stored. As the product, for example, the general name of the purchased product such as a book purchased by the user, a polo shirt, a personal computer, a DVD, etc. is stored. In addition, "merchandise" is a broad concept encompassing services such as services. As the amount of money, the purchase amount of the product is stored. The store information stores the name of the store that has purchased the product.

  Next, in step S935, the server performs control for overlaying the virtual shop on the corresponding position in the virtual world and displaying the virtual shop on the mobile phone 2. Next, in S936, when there is a questionnaire, control is performed to overlay the questionnaire virtual tag corresponding to the questionnaire and display it on the mobile phone 2. In the mobile phone 2, it is determined in S 928 whether the questionnaire virtual tag is clicked or not, and when the questionnaire virtual tag is clicked, the click signal of the questionnaire virtual tag is transmitted to the server 10 in S 929. The server 10 receives the request in S937, and transmits the questionnaire page corresponding to the clicked questionnaire virtual tag to the mobile phone 2 in S938.

  In the mobile phone 2, it is received in S 930, and control to display the received questionnaire page is performed in S 931. Next, in S932, processing for accepting an operation to which the user answers with the displayed questionnaire is performed, and in S933, processing for transmitting the response data to the server 10 is performed.

  The server 10 receives it in S939, and in S940, performs processing for registering the received questionnaire response data in the marketing database 64 as questionnaire information.

  FIG. 49 (a) is a flowchart of payment data provision processing executed by the shopkeeper client, and FIG. 49 (b) is a flowchart showing a subroutine program of the payment data collection processing shown in S906. The store merchant client determines in S945 whether or not the payment data has been updated. When the user who has entered the virtual world operates the mobile phone 2 to purchase a product or the like and performs payment processing, the payment data is transmitted to the shopkeeper, and the shopkeeper updates the payment data. Be Then, a determination of YES is made in S945, and in S946, data for performing identity authentication on the shopkeeper client is transmitted to the server 10, and processing for accessing the server 10 is performed. The server 10 receives the request in S950, and in S951 returns an access permission to the store contractor client after identity verification. The store merchant client receives it at S947, and at S948, control is performed to transmit payment update data to the server 10. The server 10 receives it in S952, and in S953, performs processing of updating the payment information (payment data) of the marketing database 64 based on the received data.

  FIG. 51 (a) is a flowchart of the marketing data acquisition process executed by the shopkeeper client, and FIG. 51 (b) is a flowchart showing a subroutine program of the marketing data provision process shown in S907. First, at the shopkeeper client, it is determined in S957 whether a marketing data acquisition operation has been performed. If the operator performs a marketing data acquisition operation at the shopkeeper client, YES is determined by S957, and control is performed to transmit a request for the marketing data to the server 10 together with data for authenticating the identity of the shopkeeper client by S958. . The server 10 receives the request in S968, and in S969, performs control to transmit the marketing menu to the shopkeeper client after identity verification.

  The shopkeeper client receives it at S959, and at S960, control is performed to display the received marketing menu. The display screen of the marketing menu according to S960 is shown in FIG. The marketing menu includes four menu items of four-dimensional coordinate data of the user, personal information of the user, payment information, and questionnaire information, and a desired item is selected from these four menu items and clicked. Then, the menu item selected in S961 is transmitted to the server 10.

  The server 10 receives it in S970, and in S971, the marketing data corresponding to the selected menu item is extracted from the marketing database 64, and in S972, control is performed to transmit the extracted data to the shopkeeper client.

  The shopkeeper client receives it in S 962, stores the received data in S 963, and determines in S 964 whether or not the display operation of the marketing data has been performed by the operator. When the display operation of the marketing data is performed, control to display the stored marketing data is performed in S965.

Modification of Second Embodiment

Search targets include conversation contents in the virtual world (in four-dimensional space-time), community virtual tags and writing pages linked to them, in a cyber special zone, in each area of the historical virtual world (see S231), shared virtual tags and It is a writing page etc. linked to it. However, in the case of a virtual space (for example, a shared virtual tag, an associated write page, a community virtual tag, an associated write page, etc.) with access restriction, only the user who is permitted access (user (Only on mobile phones 2) are displayed as search results.

  (3) The access method to the shared virtual tag described based on FIG. 5 is not limited to the shared virtual tag, and other tags, for example, a history tag, a community virtual tag, a contract shared virtual tag, business The present invention may be applied to a shared virtual tag or the like.

The following invention is disclosed in the embodiment described above.
In the case of the conventional general communicable state described in Japanese Patent No. 4256374, there are the following drawbacks.
a In many cases, it is likely that he / she feels uneasy about the point of informing the other party of the personal information such as the telephone number and the e-mail address, and this loses the opportunity for the later exchange.
b There is a risk that a person who has notified you of personal information may contact you at any time of the day or night and suffer from inconvenience.
c The personal information such as the e-mail address given to the other party may be leaked to another person, others may pretend to be the person, send e-mail, or suffer damage such as spam.
d In order to invalidate personal information that has been given, it involves troublesome tasks such as changing the phone number and changing the e-mail address.
In view of the above, in the ideal communicable state, contact can be made later without notifying the other party of each other's personal information, and another person other than the other party will come into contact as the other party. It is a state that can also prevent inconvenience.

  On the other hand, meeting people in the real world or attending events or concert venues has the disadvantage of being within a certain narrow range due to the physical limitations of the range in which people can act. is there. Also, the time when people are free is limited, and it is impossible to go to remote places within such a limited time.

  For example, an amateur photographer interested in astronomy has succeeded in shooting a total solar eclipse in Japan, and although it has been possible to establish contact with many people with the same hobbies, it will occur next in the world There is a disadvantage that the total eclipse of the sun is inconvenient and you can not visit the site.

  Ideally, it would be possible to establish contact with people in places where they would like to go, freeing them from the physical and temporal constraints of their range of activities.

  As a method of overcoming the physical limitation and the time limitation of the action range, the inventor has newly devised to utilize the characteristic that instantaneous movement is possible anywhere in the virtual world such as street view.

An example which can be considered as a method of realizing this is shown below.
i First, create a 3D virtual world on the net with an exact copy of the real world, or prepare an existing one such as street view as a virtual world.
ii. Next, measure the positions of the mobile phones of people in the real world by GPS or the like, and display the avatars of those people at the positions of the virtual world corresponding to the measured positions. This avatar preferably has an agent function.
iii Next, when another person enters the virtual world and meets the aforementioned avatar, talk with the avatar (agent) and enter the person in the real world and the virtual world through the avatar Let's talk with.

  By doing this, the avatar corresponding to the real world acts as a pipe connecting the virtual world and the real world, and it becomes possible to interact across the virtual world and the real world. Naturally, in the virtual world, the user can move instantly to a desired location and can contact a person at the location because the user can move to the location instantaneously freely in the virtual world.

  In the above-mentioned example of the total eclipse, when the total eclipse in the foreign country occurs, the location is accessed from the virtual world, and the avatar corresponding to the avatar is talked with the avatar displayed at the location in the virtual world. It becomes possible to make contact and establish a contactable state, and to exchange one another's total solar eclipse image in Japan and the other's total solar eclipse image in the other, etc. later.

  However, even in a new exchange that crosses the boundaries between the virtual world and the real world, the same problems as the above-described a to d arise in establishing a communicable state.

  The invention disclosed in the embodiments has been conceived in view of such circumstances, and an object thereof is to provide an access control system and an access control which can provide means for establishing the above-described ideal communicable state. It is to provide a method.

The invention disclosed in the embodiment meets specific persons (for example, users who meet in the real world, virtual worlds) through the network by the operation of the user terminal (for example, the mobile phone 2) operated by the user. An access control system used when the users who meet each other, the users in the real world and the users who enter the virtual world, the event organizer and the event participant) make contact with each other,
Within a predetermined geographical area (for example, within the real world, within the range where infrared communication can be performed by the mobile phone 2 or within the coverage area of the wireless LAN 7 and the mobile phone 2 that covers the event site Within the talkable area (for example, within 10 meters) between avatars (agents) of each user who entered, within the range of the virtual event venue, avatars (users) of users who entered the virtual world and the current position of the users in the real world Confirm that the person in the conversation area (for example, within 10 meters) with the avatar (agent) of the user displayed at the position of the virtual world corresponding to Confirmation means (for example, S15, S16 And S16a~S16d),
Access request receiving means (for example, receiving data transmitted at S81) for receiving a request for access to a contact sharing page (for example, a Web page corresponding to a shared virtual tag or a business shared virtual tag) for taking a contact )When,
When an access request is accepted by the access request accepting means, on condition that confirmation that consent has been taken by the confirming means has been made (for example, sharing generated through S15, S16, S16a to S16d Persons who agree with each other contact each other on condition that the access request to the shared virtual tag in S85 based on the access operation to the shared virtual tag which is a virtual tag and is displayed only to the consented person is sent) And access control means (eg, S86, S87, S91) for permitting access to the shared page for contact.

  According to such a configuration, in order to be able to make contact with the other party, contact can be made later without notifying the other party of personal information.

Preferably, the user terminal operates the user terminal in a digitally visualized virtual space (e.g., a diagram corresponding to a view of the real world (e.g., the real world shown in FIG. 1 and the upper half of FIG. 2). 1, can enter the virtual world (shown in the lower half of Figure 2),
The confirmation means enters into the virtual space and is within a predetermined geographical area within the virtual space (for example, within an area where conversations can be made between avatars (agents) of each user who has entered the virtual world (for example, within 10 meters) Within the virtual event hall, the avatar (agent) of the user who entered the virtual world and the avatar (agent) of the user displayed at the position of the virtual world corresponding to the current position of the user in the real world In-virtual-area confirmation function (for example, avatar of the user who entered the virtual world (agent) to confirm that agreement for enabling contact between persons in the conversation-enabled area (for example, within 10 meters) has been obtained ) And avatars (agents) A real also in the world of the user, S15 also determines whether the geographical area, S16, having S16a~S16d).

  According to such a configuration, when it is possible to make contact with the other party between the persons who have entered the virtual space, contact can be made later without notifying the other party of personal information.

More preferably, by operating the user terminal, the user can enter into a digitalized virtual space corresponding to a view of the real world,
The confirmation means is a person who is in the virtual space and is in a predetermined geographical area in the virtual space, and a predetermined geographical area in the real world corresponding to a predetermined geographical area in the virtual space. Inter-Real-Real confirmation function (for example, the avatar (agent) of the user who has entered the virtual world and the current position of the real-world user) confirming that consent to be in a contactable state has been obtained by the person inside It also determines S15, S16, S16a to S16d) whether or not the avatar (agent) of the user displayed at the position of the corresponding virtual world is within the conversation area (for example, within 10 meters).

  According to such a configuration, when it is possible to make contact with the other person between the person who has entered the virtual space and the person in the real world, it is possible to make contact later without notifying the other person of the personal information. It will be.

More preferably, the confirmation means is
A contact consent signal indicating that the consent transmitted according to the operation of the user terminal has been taken (for example, the transmission signal transmitted by S9 of the ID of the other user consent received by infrared communication in S3 for the variable shared virtual tag) Means for receiving consent signal (for example, the server 10 receives the transmission signal transmitted by S9);
An in-area determination unit (for example, S16, S16a to S16d) that determines that the position at the time of consent of the consented user is within the predetermined geographical area (for example, S16, S16a to S16d);
Consent of a person within a predetermined geographical area on condition that it is determined to be within the predetermined geographical area by the in-area judging means (for example, on the condition that the judgment is YES by S16 d) (For example, it is confirmed that the consent has been obtained by determining YES by S16 d, and the process proceeds to shared virtual tag generation processing in S17 and subsequent steps).

  According to such a configuration, it is determined that the consent of the person within the predetermined geographical area is obtained, provided that the position of the consented user at the time of agreement is determined to be within the predetermined geographical area. As a result of the confirmation, it is possible to make a more reliable confirmation, for example, it is possible to prevent the contact by imitation as much as possible.

More preferably, the in-area determination unit
Position information acquisition means (for example, S16a, S16c) for acquiring position information of the user terminal;
Determining means (for example, S16 d) for determining whether the user terminal is located in the predetermined geographical area based on the position information acquired by the position information acquiring means;
On condition that the determination means determines that the user terminal is located in the predetermined geographical area (for example, on the condition that YES is determined by S16 d), the position at the consent time of the user terminal is the predetermined geographical A determination is made that the area is within the area (for example, by determining YES by S16 d, it is determined that the position at the agreement point is within the predetermined geographical area, and the process proceeds to shared virtual tag generation processing after S17. To do).

  According to such a configuration, position information of the user terminal is acquired, and based on the position information, it is determined whether or not the user terminal is located within a predetermined geographical area. In order to confirm that the consent of the person within the predetermined geographical area has been obtained based on the positive determination of whether or not the user is located within Can be prevented as much as possible.

More preferably, the user terminal can perform communication within a limited range (for example, infrared communication between mobile phones 2 and wireless communication by a wireless LAN access point 7) that can communicate only within the predetermined geographical area. Have
The in-area determination means includes, in the contact consent signal received by the consent signal reception means, communication information (for example, a variable shared virtual tag ID) from the user terminal communicated by the in-limit range communication function. On the condition that the location of the user terminal at the time of consent is within the predetermined geographical area (for example, on the condition that information including the variable shared virtual tag ID has been transmitted in S9). (For example, the process of S10 is performed and the process after S17 is performed).

  According to such a configuration, the user terminal is conditioned on the condition that the communication information from the user terminal communicated by the in-limited-range communication function capable of communication within the predetermined geographical area is included. It is determined that the location at the point of agreement of the subject is within the given geographical area, and it is confirmed by a relatively simple and easy decision method that the consent of the person within the given geographical area has been obtained. For example, it is possible to prevent as much as possible contact by imitation.

More preferably, on the condition that confirmation that consent has been obtained by the confirmation means has been made (for example, shared virtual tags generated via S15, S16, S16a to S16d and displayed only to those who agreed Access to the shared virtual tag in S85 based on the access operation to the shared virtual tag not being sent), the predetermined geographical area in the digitalized virtual space corresponding to the landscape of the real world) Access point generation means (e.g., S17 to S19 or S17, S200) for generating an access point (e.g., shared virtual tag) dedicated to the agreed party that the agreed party accesses in order to contact each other , S201, S18, S19),
When an access request is accepted by the access request accepting means (for example, when data is received in S81), only for the person who made the access request among the access points created by the access point creating means The generated access point (for example, the shared virtual tag corresponding to the user ID transmitted at S81) is displayed to the access requester together with the image of the virtual space corresponding to the geographical position where the access point is generated. An access point display control unit (for example, S87) that performs control for
The access control means allows access to the contact shared page corresponding to the access point by the user operating the user terminal to access the access point (for example, S91).

  According to such a configuration, the access point generated exclusively for the person who made the access request is displayed on the access requester together with the image of the virtual space corresponding to the geographical position where the access point is generated. Even without knowing the personal information of the person making the contact, it is possible to restore the memory of the person from the image of the virtual space corresponding to the geographical position.

  More preferably, the confirmation means confirms that an agreement for enabling contact can be obtained between the organizer of the event and the participants in the event (for example, shared shared virtual tag for business use) In the generation process, S15, S16, S16a to S16d).

  According to such a configuration, it becomes possible to make contact later between the organizer of the event and the participant in the event without notifying the other party of the personal information, and the participant can While the notices and messages from the organizer can be obtained, the organizer of the event can construct a pipe with the participants (users).

Another aspect of the present invention is that, when a user terminal (eg, mobile phone 2) operated by a user operates a specific person (eg, users who meet in the real world, users who meet in the virtual world) via the network An access control system used when people who meet each other between a user in the real world and a user who has entered the virtual world, an event organizer side and an event participant) make contact with each other,
Within a predetermined geographical area (for example, within the real world, within the range where infrared communication can be performed by the mobile phone 2 or within the coverage area of the wireless LAN 7 and the mobile phone 2 that covers the event site Within the talkable area (for example, within 10 meters) between avatars (agents) of each user who entered, within the range of the virtual event venue, avatars (users) of users who entered the virtual world and the current position of the users in the real world Confirm that the person in the conversation area (for example, within 10 meters) with the avatar (agent) of the user displayed at the position of the virtual world corresponding to Confirmation means (for example, S15, S16 And S16a~S16d),
An access control means (for example, S86, S87, S91, or the other party is a contact method other than the shared virtual tag) (eg, S86, S87, S91, or the like) on the condition that confirmation has been made by the confirmation means. , Exchange e-mail addresses and telephone numbers with each other if the requester of shared virtual tag generation agrees with the request).
The confirmation means is
A contact consent signal indicating that the consent transmitted according to the operation of the user terminal has been taken (for example, the transmission signal transmitted by S9 of the ID of the other user consent received by infrared communication in S3 for the variable shared virtual tag) Means for receiving consent signal (for example, the server 10 receives the transmission signal transmitted by S9);
An in-area determination unit (for example, S16, S16a to S16d) that determines that the position at the time of consent of the consented user is within the predetermined geographical area (for example, S16, S16a to S16d);

  According to such a configuration, it is possible to prevent the inconvenience of notifying the personal information of the other party who is not desirous of notifying the personal information so much that contact with the other person can be made. Furthermore, because it is confirmed that the consent of the person within the predetermined geographical area has been obtained on the condition that the position at the time of consent of the consented user is determined to be within the predetermined geographical area. In addition, more reliable confirmation is possible, and for example, it is possible to prevent contacts by impersonation as much as possible.

Another aspect of the present invention is that, when a user terminal (eg, mobile phone 2) operated by a user operates a specific person (eg, users who meet in the real world, users who meet in the virtual world) via the network An access control method used when people who meet each other between a user in the real world and a user who has entered the virtual world, an event organizer side and an event participant) make contact with each other,
Within a predetermined geographical area (for example, within the real world, within the range where infrared communication can be performed by the mobile phone 2 or within the coverage area of the wireless LAN 7 and the mobile phone 2 that covers the event site Within the talkable area (for example, within 10 meters) between avatars (agents) of each user who entered, within the range of the virtual event venue, avatars (users) of users who entered the virtual world and the current position of the users in the real world Confirm that the person in the conversation area (for example, within 10 meters) with the avatar (agent) of the user displayed at the position of the virtual world corresponding to Step (for example, S15, S16, S1 And a~S16d),
Accepting a request for access to a contact sharing page (eg, a web page corresponding to the shared virtual tag) for taking a contact (eg, receiving the data sent at S81);
When an access request is accepted in the step of accepting the access request, it is generated on the condition that confirmation has been made that consent has been taken in the confirmation step (for example, generated through S15, S16, S16a to S16d Who have agreed to access the shared virtual tag in S85 based on the access operation to the shared virtual tag, which is displayed only for the agreed parties) who have agreed to each other) And (e.g., S86, S87, S91) allowing access to the contact sharing page for taking an e-mail.

  According to such a configuration, in order to be able to make contact with the other party, contact can be made later without notifying the other party of personal information.

Another aspect of the present invention is that, when a user terminal (eg, mobile phone 2) operated by a user operates a specific person (eg, users who meet in the real world, users who meet in the virtual world) via the network Access control system used when people who meet each other, users in the real world and users who enter the virtual world, event organizers and participants in the event, people who encounter a certain event contact each other) And
