DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service providing system, method and apparatus, and more particularly to a technique for providing an appropriate service to a user using a computer network.

[0002]

2. Description of the Related Art Recent advances in Internet technology have made it possible to purchase desired products and services using terminals connected to a computer network without actually going to a store such as online shopping or electronic commerce. Has become. For example, merchandise or service data is stored on a WWW server, and a Web page is transmitted to a user terminal. The transmitted Web page is displayed on the user terminal using a browser or the like, and the user selects a necessary product or service and transmits a purchase request to the WWW server. The WWW server performs necessary payment processing and provides the requested product or service to the user.

[0003]

As described above, the advantage of electronic commerce using a computer network is that there is no spatial restriction, and that goods and services provided by a remote store can be freely purchased or enjoyed. But
On the other hand, when the actual address of the user is spatially separated from the store that provides the product or service, there may be a problem that the provided product or service does not always match.

[0004] For example, when a user wants to receive a nursing care service or the like, the user often wants to know the situation of a nursing care facility located at a short distance from his / her home. Absent. In such a case, in the conventional system, for example, a user has to specify his / her own address on a Web page and search for a nearby facility by narrowing down or searching for nursing care facilities nationwide.

[0005] It is also conceivable to provide administrative services such as issuance of a resident's card on a computer network. However, it is troublesome to search, for example, government offices in charge of one's address from a list of government offices nationwide. It is preferable that information other than the government office that controls the address of the user is unnecessary information and is not provided to the user.

[0006] Further, it is well-known that there is a regional difference in the tastes of the users, and the tendency is remarkable in foods and the like, so that the provision of products or services is uniform for all users. It is expected that the satisfaction of users will be higher when providing local products or services than when providing services.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the related art, and an object of the present invention is to provide a system for providing a service to a user using a computer network to ensure that a proper service is provided to an accessed user. It is an object of the present invention to provide a system and a method which can be provided to a user.

[0008]

According to the present invention, there is provided a system for providing a service on a computer network, the system comprising a server computer and a client computer connected to each other by a communication line. Wherein the server computer comprises: storage means for storing service data; and control means for reading out the service data from the storage means and supplying the service data to the client computer in response to a request from the client computer. A computer for displaying a virtual city including a virtual facility to which the service data is to be provided; a means for outputting a request to a server computer at the virtual facility; Service provided by computer And having a means for outputting the data. By displaying a virtual city including a virtual facility as a user interface and requesting data transmission at the virtual facility, the user is provided with various services as if in a real city (or city). Can be felt like this, and the usability can be improved.

Here, the server computer has a second storage means for storing user-specific information, and a user who has made a request in response to a request from the client computer using the information stored in the second storage means. It is preferable to have control means for specifying an area to which the service belongs, reading service data of the specified area from the storage means, and supplying the service data to the client computer. When a service request is issued from a client computer, the server computer does not provide uniform service data to the client computer, but reads and supplies service data in the area to which the user belongs. As a result, the user can obtain a service specific to his or her area on the computer network. Service data for the region to which the user belongs includes administrative services,
The data includes medical facility data, welfare facility data, store data, and the like. In the present invention, since the server computer automatically specifies the area to which the user belongs, the user does not need to specify the area to which the user belongs on a search screen or the like, and the operation is simplified.

[0010] The control means further specifies personal characteristics of the user who made the request using the information stored in the second storage means in response to the request from the client computer, and provides a service in the specified area. It is preferable that only data matching the personal characteristic is read out from the storage means and supplied to the client computer. The user's personal characteristics include the user's age and gender. By providing service data according to the user's personal characteristics, a more optimal service can be provided. That is, even if the users A and B belong to the same area, the required service contents are generally considered to be different depending on their age and gender. Therefore, by considering not only the area but also these individual characteristics, it is possible to provide a so-called custom-made service that matches the user. It is desirable that the user's personal characteristics be automatically determined by the server computer instead of being separately input by the user on a search screen or the like.

It is preferable that the display means of the client computer displays the inside of a virtual room and displays the virtual town in a part of the inside of the virtual room. This allows the user to receive a service in a virtual city by an action similar to the action in the real world, such as going out of a virtual room to a virtual city, further improving the usability of the system.

Further, the client computer includes:
It is preferable to provide an electronic tool linked to the virtual facility data. Thus, immediate processing can be performed on the facility using the electronic tool. An electronic tool linked to facility data is an electronic tool that is specific to or includes the facility data.For example, if the electronic tool is an e-mail, This is an e-mail customized to be suitable for use of the e-mail, or an e-mail to which data of the facility is added. The electronic tool realizes functions such as memo pad, mail, and schedule using software. Specifically, for example, e-mail, TV phone, electronic bulletin board, electronic schedule book, electronic cabinet, address book, It can be at least one of notepad and bookmark.

[0013] The present invention also relates to a method for providing a service on a computer network, wherein the server computer transmits a service request to a virtual facility in a virtual city displayed on a client computer. And outputting the service data stored in the database of the server computer and matching the service request to the client computer. It is preferable that the server computer specifies an area to which the user who has output the service request belongs, reads out service data matching the specified area from the service data stored in the database, and outputs the service data to the client computer.

Further, the server computer further specifies personal characteristics of a user who has output the service request,
It is preferable that, of the service data that matches the specified area, service data that further matches the characteristic is output to the client computer.

It is preferable that the client computer displays the inside of a virtual room, and that the virtual town is displayed by operating a part of the virtual room. Thereby, it is possible to have consistency with the real sense of going out of the room.

Further, the client computer comprises:
It is preferable to display an icon for providing an electronic tool linked to the virtual facility data together with the virtual facility. The form of the icon is arbitrary,
By operating this icon, the user can easily transmit data on the facility to, for example, a third party, and can share the data on the facility with the third party.

In the present invention, the client computer includes an arbitrary device that includes an arithmetic processing device, an input device, and an output device and can be connected to a computer network, and a PDA and a mobile phone are also one embodiment.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a system configuration diagram of the present embodiment. On the server side, WWW server 10, mail server 12, CTI (Computer Telephony Integrati)
on: fusion of telephone and computer) A server 14 is provided. The WWW server 10 and the mail server 12 are connected to a main (system) server 16, and the main server 1
6 receives the provision of a Web page and the provision of an e-mail. A database 18 storing store information, product information, or user information is connected to the core server 16, and the store information and product information are provided to the user using the WWW server 10. Also, the user information is the user's name, age,
It is composed of an address, a user ID, a password, and the like. Based on these pieces of user information, only information appropriate for the accessed user is selected and provided to the user. The core server 16 is connected to a settlement / distribution server 22 such as a financial institution or a logistics company, and executes settlement processing or delivery processing by transmitting / receiving data to / from these servers.

On the other hand, the WWW server 10 and the mail server 1
2 is connected to the Internet 26 via a firewall FW 24, and a client computer (terminal) 28 operated by a user is connected to the Internet 26. The user can access the WWW server 10 via the Internet 26 using the client computer 28, receives the Web page sent from the WWW server 10, displays the Web page on the display provided on the client computer 28, and displays the store information and the product information. And so on. The Web page desired by the user is specified using the URL, and the URL is transmitted using the browser installed on the client computer 28, and the WWW is transmitted.
A technique for receiving and displaying a Web page supplied from the server 10 is known.

The CTI server 14 is connected to a pager (registered trademark) (pager) 32 and a telephone 3 via a public line 30.
4. Connected to the facsimile 36, it is possible to access the mail via the telephone 34, supply the contents of the mail to the telephone and output it by voice, or output the mail from the facsimile 36.

In such a system configuration, when the user accesses using the client computer 28, the main server 16 recognizes the address and personal characteristics of the accessing user based on the user information stored in the database 18, Store information and merchandise information that match the recognized address and personal characteristics are selected and provided to the user via the WWW server 10. That is, in the present embodiment, the area to which the user belongs is specified for the accessing user, and information specific to the specified area is provided to the user. Therefore, if the region to which the accessing user belongs is different, the information provided from the main server 16 or the WWW server 10 is also different. From the user's point of view, different information is displayed for each user even when accessing the same Web page.

The user's personal information can be supplied to the server side in advance by the user offline. For example, a user who wants to use this system makes a registration application to the server administrator by mail, and specifies the name, address, age, and the like of the user in the registration application. On the server side, personal data such as the address and age supplied from the user are stored in the database 18. The server provides the login ID and password assigned to the user by mail or the like. In this way, the address and age of the user are stored in the database 18 together with the ID and the password. Of course, if security is sufficiently secured by encryption, etc., the database 18 can be used online.
May be registered with the user's personal information.

After the personal information has been registered, when the user accesses the server using the client computer 28, the main server 16
Requesting input of a login ID and a password from the client computer 28. When the user inputs these IDs and passwords from the client computer 28, the main server 16 compares the input ID and password with the user personal information stored in the database 18. After collation, the personal information of the accessed user, particularly the area to which the user belongs is specified, and information unique to the area is selected and provided. In order to select product information or service information specific to the region to which the user belongs, an identification flag for each region is added in advance to the product information or service information, and information having a flag that matches the region to which the accessed user belongs is added. Search and extract. For example, product information a and b exist, and a Kanto flag is set for the product information a, and a Kansai flag is set for the product information b. If the accessing user belongs to Kanto, the merchandise information a having the Kanto flag is selected and provided.

Hereinafter, the main server 16 is the WWW server 10

FIG. 2 shows a screen displayed on the display of the client computer 28 when the ID and password entered by the user are authenticated and the user is determined to be registered in the database. This screen is a screen assuming that the user is in a study at home. On the screen, an image 100 of a desk, an image 102 of a notebook,
Alternatively, an electronic tool icon such as the image 104 of the display device is displayed. Of course, although not shown, it is also preferable to display, for example, an image of a bookshelf. When the image of the notebook is clicked, schedule management software, address book management software, or memo pad software is activated and displayed on the display. Also, if you click on the bookshelf,
The Web page of the electronic library is displayed, and a necessary book can be searched and displayed. Of course, other electronic stationery can be displayed, and it is preferable to provide functions such as electronic mail, voice mail, and fax. Schedule management software and other software are not installed on the client computer 28 side, but are installed on the server side (backbone server).
It is also preferable to download from the server to the client computer in response to a request from the client computer 28. This allows the user to always use the latest software.

A window image 106 is displayed on the study screen (virtual office).
Click 6 to get out of the study into the virtual city. It is preferable that an image of the virtual city be further displayed on the window image 106 through the window. In the real world, you need to walk on your way from the study to the city, but in an electronic virtual world, you can go from the study to the city with just a click.

FIG. 3 shows a screen displayed on the display of the client computer 28 when the user clicks the window image 106 on the screen shown in FIG. 2 and makes an intention to enter the city from the study. . When the user clicks on the window image, a predetermined command is transmitted to the main server 16, and the main server 16 receives the command and transmits a Web page describing the virtual city to the client computer 28. By displaying the Web page transmitted from the backbone server 16 with a browser or the like, the screen shown in FIG. 3 is displayed on the display. This screen is basically a screen for providing almost all functions of the city (also referred to as a portal site). In the figure, there are seven categories, namely, public,
Arts, business, living, shopping, leisure,
The services are categorized and displayed. These seven categories are displayed at different positions on the screen as shown in the figure, and are displayed as if they exist in different zones in the virtual city. The user can receive these services by moving to a desired zone in the virtual city displayed on the screen. Note that the seven categories are examples, and can be classified into more detailed categories or different categories.

FIG. 4 shows a screen when the user arrives at the public zone in the screen of FIG. To reach the public zone, the user may virtually walk along the road displayed on the screen of FIG. 3 (specific operation is, for example, clicking along the road) or FIG.
By clicking the icon of the public zone in, the public zone may be immediately reached. When the user reaches the public zone, a command to that effect is transmitted to the main server 16. The key server 16 recognizes from the command that the user has reached the public zone, and transmits a prepared public zone Web page to the client computer 28.

In FIG. 4, six types of information are displayed in the public zone. The telework center, facility reservation center, home care support center, volunteer network,
City hall and news are displayed. Of course, what kind of information is displayed is arbitrary, and other information such as a list of available facilities can also be displayed.

FIG. 5 shows a screen displayed when the user arrives at the shopping zone on the screen shown in FIG. When the user arrives at the shopping zone, a command to that effect is transmitted to the main server 16. The backbone server 16 transmits a Web page for the shopping zone to the client computer 28. In the shopping zone, information on fashion, beauty, hobby, interior, goods, and food is displayed. The user selects necessary information from these pieces of information. Of course, other information may be displayed in FIG.

FIG. 6 shows a screen when the user arrives at the service zone in the screen of FIG.
In this service zone, weather forecast, recruitment,
Rankings, press releases, news and traffic information are displayed. The user can select desired information from these pieces of information and display it on a display.
For example, when news is desired, the user clicks news on the screen of FIG. The command for selecting the news is supplied to the main server 16 via the Internet 26. The main server 16 supplies the news data stored in the database 18 to the WWW server 10 in the form of a Web page, and the WWW server 10 transmits the Web page to the client computer 28. The client computer 28 displays a Web page describing the news supplied from the WWW server 10 on a display by a browser. Of course, other information may be displayed in FIG.

In the above-described example, the screen of FIG. 2 is displayed when the user ID and password are authenticated. However, the user clicks a window on the screen of FIG. The user may be required to input an ID and a password at the time of the operation. In this case, the user's ID and password are a permit to enter the virtual city,
Alternatively, it can be said that it functions as authentication of being a citizen of a virtual city. If the user's ID and password match the ID and password registered in the database 18 in advance, the user is authenticated as a citizen of the virtual city and can receive various services. A user who does not have an ID and a password can also be permitted to enter a virtual city. In this case, a service different from the residents of the virtual city is provided. This is because an appropriate service cannot be provided because the area to which the accessing user belongs is not specified.

Now, the difference between the users registered in the virtual city (citizens of the virtual city) and the user B who does not have access will be described with reference to an example.

FIGS. 7 and 8 show screens displayed on the display of the client computer 28 when the user A who is a resident of the virtual city accesses. First, FIG. 7 shows a screen displayed when the user clicks the facility list. The core server 16 stores the user A who has accessed the database 18
When the user A is determined to be a citizen on this virtual city, the data necessary for the citizen is acquired from the database 18 and provided to the client computer 28. Specifically, a government office, a welfare facility, a medical / health facility, or the like that has jurisdiction over the user's address is displayed. When there are a plurality of welfare facilities, these facilities are displayed in a list. When there are a plurality of medical / insurance facilities, a list is displayed as c1 hospital, c2 doctor, c3 doctor, etc., as shown in the figure. Note that the government office, welfare facilities, and medical / insurance facilities are facilities near the address of the user A. In particular, welfare facilities and medical / health facilities have a high necessity for the user to actually go to the facility, and it is preferable to provide only facilities near the user's address. The user can select a desired facility from these list displays to obtain detailed information. Of course, in addition to facilities near the address of the user, a list of facilities nationwide can be displayed. In this case, it is desirable to give a priority between the two.

FIG. 8 shows a screen when the user A clicks the c1 hospital of the medical / health facility on the screen of FIG. The medical record information of A who is a citizen of the virtual city is also stored as personal information in the database 18 (this medical record information is appropriately transmitted from the c1 hospital to the main server 16).
The main server 16 reads out and displays the doctor in charge (doctor X) from the medical record information of the user A. Further, it is desirable to display a comment from Doctor X. In the figure, a comment "A, how are you doing?" Note that the medical record information of the user A is not stored in the database 18 and the user A
At the time when one hospital is clicked, the core server 16 may access a computer system in the c1 hospital, read out and provide the user A's medical record information stored in the c1 hospital. Also, the screen displays "Back" as a menu,
When “health data” is displayed and the user clicks on the health data, the health data of user A included in the medical chart information is read and displayed.

On the other hand, FIGS. 9 and 10 show screens displayed on the display of the client computer 28 when the user B who is not a citizen of the virtual city accesses the screen. When user B clicks on the facility list,
A facility guidance screen as shown in FIG. 9 is displayed. Since the user B is not a citizen of the virtual city, no government office is displayed, and regarding the welfare facilities and medical / health facilities, not the facilities near the address of the user B, but the hospitals arbitrarily picked up nationwide. A list is displayed (the welfare facilities are omitted in the figure for simplicity). The user B can select a desired hospital from these hospitals displayed in the list.

FIG. 10 shows a screen displayed when the user clicks on d1 hospital from the displayed list on the screen shown in FIG. Since the user B is not a citizen of the virtual city, the medical record information of the user B is not stored in the database 18 either.
Only basic information of the hospital, for example, a medical subject is displayed. The user B appropriately obtains necessary information by selecting the “next” menu.

It is assumed that both users C and D are citizens of a virtual city, but user C has an address in Kanto and user D has an address in Kansai. In this case, when both the users C and D purchase food in the shopping zone, for the user C, the core server 16 searches the database 18 for only the product information with the Kanto flag added thereto and provides it to the client computer 28. I do.
For the user D, the core server 16 retrieves only the product information with the Kansai flag from the database and provides the retrieved information to the client computer 28. Thus, the user can easily find his or her favorite product. Of course, it is possible to provide the product information with the Kansai flag provided to the user C and to provide the product information with the Kanto flag added to the user D. It is desirable to provide the information of the area to which the user belongs with priority.

In the present embodiment, it is also preferable to change the service content to be provided based on not only the address of the accessing user but also the age and gender of the user. For example, when the user E who is a citizen of the virtual city is a male, it is preferable that the beauty zone is deleted or replaced with another zone on the shopping screen of FIG. If the user is a young user, the product information to be provided by hobby is increased.

As described above, in the present embodiment, an actually existing city function is virtually constructed on a computer network, and an optimum service is provided based on personal information such as a user's address. Can obtain an appropriate service without actually visiting a store or a facility.

On the other hand, when trying to receive a service at various facilities in a virtual city (virtual city), there is a case where the user wants to communicate with a third party at a specific facility. For example, when a user accesses a virtual store in a shopping zone, there may be a case where a third party such as a friend wants to have an opinion on a product desired to be purchased. In the prior art, in such a case, e-mail software is separately activated, an e-mail is sent to the third party, and the address of the virtual store (for example, UR
L) and the like need to be input and transmitted. In this embodiment, an electronic tool capable of efficiently communicating with a third party is provided to the user in such a case.

FIG. 11 shows an example of a screen when the user accesses the shopping zone. At the upper right of the screen, a bag icon 200 is displayed. The bag icon 200 activates an electronic tool such as an e-mail, a TV telephone system, an electronic bulletin board, and an electronic address book, and is activated when the user wants to communicate with a third party in the shopping zone. Of course, the display position of the icon 200 can be arbitrarily changed, and the form of the icon 200 can be variously set. By using the bag icon 200, it is possible to give a feeling that the user is carrying these electronic tools and walking around the virtual city.

FIG. 12 shows an example of a screen when the user operates the bag icon 200 in FIG. A window 202 showing the contents of the bag is newly displayed on the screen, and icons of various electronic tools are displayed in the bag. In the figure, the e-mail icon 2
04, a TV telephone system icon 206, a memo pad icon 210, and an electronic cabinet icon 208 are displayed. These electronic tools are not activated independently of the web page accessed by the user as in the related art, but are activated by linking to the web page. For example, if the user asks a third party for an opinion on a product in the shopping zone, the e-mail icon 2
When the e-mail software is started by operating the electronic mail software 04, the e-mail software acquires an address (URL) of a Web page displaying the product and reflects the acquired address on the e-mail. The address of the top page of the Web page displaying the product or the copy screen can be automatically reflected. That is, the data of the Web page accessed by the user at the time of starting the e-mail software is automatically added to the e-mail. Therefore, when the user sends the e-mail to the third party, it is not necessary to separately transmit the Web page address as in the related art, and the third party can communicate efficiently.

When the user wants to communicate with a third party by TV telephone about the goods in the shopping zone, the user operates the TV telephone icon 206. Then, the third
A videophone conversation with a third party is possible, but the videophone system automatically obtains the URL of the Web page currently being accessed by the user and displays the screen shared with the third party on this URL. Set to the screen specified by. This allows the user and the third party to have a smooth conversation while looking at the same screen.

When a special event is present in the shopping zone, when the user operates the electronic schedule book and starts up, the electronic schedule book software acquires the event data in the shopping zone from the server computer and displays it on the screen. To be displayed. The user can efficiently perform shopping by looking at the schedule book.

As described above, by providing an electronic tool by linking virtual facility data, for example, the address and event data of the facility, rather than simply making the electronic tool available, a virtual city is provided. Access and communication can be seamlessly connected to improve user experience.
