     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present disclosure relates to subject matter contained in Japanese Patent Application No. 2000-012314, filed on Jan. 20, 2000, the disclosure of which is expressly incorporated herein by reference in its entirety.  
         [0004]     The present invention relates to an information servicing method for servicing online informations beneficial for a user, a recording medium recording with a program for realizing the method, and an information servicing system.  
         [0005]     2. Related Art  
         [0006]     In the internet, there has already been known the technique to distribute the information such as an advertise beneficial for the user to the terminal of the user. The technique of this kind is disclosed in U.S. Pat. No. 5,740,549. Normally, the screen saver is started for the idle time period in which no input is given for a predetermined time period from the user. Here, the idle time period is effectively exploited for servicing the advertise demanded by the user.  
         [0007]     As a similar technique, on the other hand, there is disclosed in Unexamined Published Japanese Patent Application No. 11-511574 a technique by which an advertise is selected from the computer network database on the basis of a preference made by the user so that the received advertise is displayed by the screen saver.  
         [0008]     According to the above-specified Publication, an operation to select the information desired by the user in advance is required, and the selected information is serviced to the user through the screen saver. In this case, what is done is to serve the selected information one way through the screen saver. The actual state is that even the selected information can attract no attention so long as it is not beneficial at that time.  
         [0009]     As the network infrastructure spreads in recent years, the time period for utilizing the network in the business and private fields has occupied most of daytime. Under this environment, it is expected to service informations in close contact with the life of the user.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0046]     One embodiment of the invention will be described in detail with reference to the accompanying drawings.  
         [0047]      FIG. 1  is a block diagram for explaining an entire system according to an embodiment of the invention. As shown in  FIG. 1 , for example, this system connects clients  1  and so on and a push server  2  with a network, through which it makes communications. With this network, there are additionally connected a game server, a server for distributing comics, a server for distributing musics, a server for controlling male exchanges, a server for controlling chats and so on, although not shown.  
         [0048]     To this system, on the other hand, there can be applied a technique such as the business network or the internet. Where the business network or the internet is to be applied to the system, there is needed the environment in which the services can be utilized after the authentication of a user was obtained by a dial-up from each client  1  to the closest server. In the case of a connection with the network, this connection has to be made with the provider through a modem.  
         [0049]     Here will be further described the individual devices. Each client  1  is provided with a recording medium  11 , in which is recorded personal information  11 A including preference data and a schedule, a user ID  11 A necessary for the user authentication, a screen saver  11 C to be started if the user&#39;s operation is absent for a constant time period, a push demand program  11 D for demanding the push server  2  the push distribution of the information as the screen saver  11 C is started, a game program  11 E for executing the game, and so on. The recording medium  11  may be exemplified by a hard disk.  
         [0050]     The recording medium  11  may be fed with the game program  11 E from a disk medium, such as a CD-ROM, a DVD or a floppy disk. The game program  11 E indicates an online dedicated game program or an offline dedicated game program.  
         [0051]     The user ID  11 B is utilized for discriminating the legal user to receive the individual services.  
         [0052]     Each client  1  is connected with a display  12  for displaying the image and outputting the sound for the client of each server, and a keypad  13  for the user to input the operations. The various services are provided through the display  12  and are controlled through the keypad  13 .  
         [0053]     The push server  2  is connected with the network and is provided with an information database  21 , an information correlating database  22 , a server engine  23  and so on. The push server  2  decides correlation between the informations to be pushed, from the personal information sent at a push demanding time from each client  1 , and collects and serves the informations on the basis of the decision. The information database  21  is a database for collecting and registering the latest information for the prepared categories. The information correlating database  22  decides the correlation of the informations to be pushed, from the personal information sent from each client, and specifies the rule for determining the combination of the informations to be pushed, from that decision.  
         [0054]     The server engine  23  is an engine for administering the operations of the push server  2  itself, and contains controls for updating the content of the information database  21  periodically or at a proper timing.  
         [0055]     The personal information to be registered in each client  1  will now be described.  FIGS. 2A and 2B  are diagrams for explaining one example of the personal information. Of the personal information, one example of the preference data is shown in  FIG. 2A . The preference data include Hobby, Favorite Singer, Favorite Star, Interesting Country, Favorite Food, Favorite TV Program, Favorite Study, Favorite Home Page, Information on Friend/Acquaintance, Information on Family, Favorite Game, and Game Being Played, for example. Here, the preference data naturally include the additional various ones because they indicate the preferences of the user.  
         [0056]     For example, Information on Friend/Acquaintance or Information on Family covers Birthday, Address or Place of Employment, and Game Being Played covers the information on whether or not the game is an online one serviced through the network. On the other hand, Favorite Game covers the information such as a favorite game maker or a genre.  
         [0057]     Of the personal information, one example of the schedule is shown in  FIG. 2B . This schedule includes the general information such as Daily Schedule or Scheduled Action Item.  
         [0058]     Here will be described the information database  21  in detail.  FIG. 3  is a diagram for explaining information examples of different categories to be registered in the information database  21 . This information database  21  is stored, as shown in  FIG. 3 , with: Advertise Data for advertising commodities or enterprises; Shopping Guide Data for guiding shops of individual countries or individual areas; Weather Data for introducing weather forecasts or present weathers of individual areas; News Data of sports, events or politics; Travel Data for guiding domestic or abroad travels; Restaurant Guide Data for Guiding restaurants of individual areas or needs; Hotel Guide Data for guiding hotels of individual areas or needs; or Game information for guiding games of different genres or makers. These data and informations are serviced through the network from other servers, as shown in  FIG. 2 , and are updated.  
         [0059]     Here will be described the functions of the information correlating database  22  in detail.  FIGS. 4A, 4B  and  4 C are diagrams for patterning and explaining the correlations of informations by using the information correlating database  22 .  FIG. 4A  shows Pattern  1 . This Pattern  1  implies that from the correlation between the birthday of the user and the title of the game being played on the online, an item beneficial for the game is presented on that birthday.  
         [0060]      FIG. 4B  shows Pattern  2 . This Pattern  2  proposes a reasonable travel plan for the user to make during the summer vacation, from the correlation between a country the user is anxious to visit (or a country interesting the user) and the summer vacation allowed by the user&#39;s schedule.  
         [0061]      FIG. 4C  shows Pattern  3 . This Pattern  3  proposes the famous restaurant which can be introduced by the destination and the time zone of the user, from the correlation between the schedule (i.e., place and time) of data allowed by the user&#39;s schedule and the present time. If the weather forecast is additionally combined in this case, it is possible to realize the services of a more beneficial information. Where the weather is pushed, there may be prepared a routine comment. If it is forecast to rain outdoors at the destination, it may be set to make an advice “Let&#39;s bring an umbrella!”.  
         [0062]     Patterns  1 ,  2  and  3  are just examples, and it is arbitrary to correlate three or more kinds of informations or to select the information directly with one kind.  
         [0063]     Here will be described the actions according to this embodiment.  FIG. 5  is a flow chart for explaining an example of operations to register the personal information in this embodiment, and  FIG. 6  is a flow chart for explaining an operation correlating example between the client and the push server.  
         [0064]     First of all, a method of registering the personal information will be described with reference to  FIG. 5 . At each client  1 , the menu is displayed at first (at Step S 10 ) by inputting the operations by the user. This menu contains the registration of the personal information. In view of this menu display, the user selects a desired item (at Step S 11 ).  
         [0065]     Where the registration of the personal information is selected (on the Yes route of Step S 12 ) through the operations of the user, there is displayed a sub-menu which is divided into the categories of “Schedule” and “Preference” of the user. If the “Schedule” is then selected by the user (on the Yes route of Step S 13 ), the schedule is inputted and registered (at Step S 14 ). Here, the registration contents have already been described with reference to  FIG. 2B .  
         [0066]     If the “Preference” is selected (on the No route) at Step S 13 , on the other hand, the preference is inputted and registered. Here, the preference contents have already been described with reference to  FIG. 2A .  
         [0067]     Thus, the registration at each client  1  is completed.  
         [0068]     The push demand and the push distribution method will be described with reference to  FIG. 6 . At the client  1 , in response to the operation input (on the Yes route of Step S 101 ), there are executed a variety of operations (at Step S 102 ). Without the operation input (on the No route of Step S 101 ), it is decided (at Step S 103 ) whether or not the idle time has elapsed for a constant period  
         [0069]     While the lapse of the constant period is not confirmed (on the No route of Step S 103 ), the routine returns to Step S 101 . If the lapse of the constant period is confirmed (on the Yes route of Step S 103 ), there is started the screen saver for preventing the burning of the screen. As this screen saver is started, the processing is switched to the background (at Step S 104 ).  
         [0070]     Then, the registered personal information is transmitted to the push server  2  (at Step S 105 ), and the routine is on standby till the push information arrives. When the push information is received (at Step S 106 ), it appears on the starting screen of the screen saver so that it is so displayed (at Step S 107 ) as to be visually recognized by the user.  
         [0071]     In the display of the push information, a click may be set to jump to the Web page. In this case, the Web page is connected directly from the client  1  by the clicking operation of the user. In this case, the operation input is detected (on the Yes route of Step S 108 ) through the jump to the Web page, the start of the screen saver is interrupted, and the switched background is restored (at Step S 109 ). Then, the routine returns to Step S 101 .  
         [0072]     While no operation is inputted (on the No route of Step S 108  after the display of the push information at Step S 107  and while no constant period is elapsed (on the No route of Step S 110 ) after the start of the screen saver, the operations of Step S 108  and Step S 110  are repeatedly executed. If the lapse of the constant period is confirmed, on the other hand, the routine returns to Step S 110 , and the personal information is transmitted again to the push server  2 . If the information database  21  of the push server  2  is updated at this time, the latest information can be acquired real-time.  
         [0073]     At the push server  2 , on the other hand, if the personal information is received from the client  1  (at Step S 201 ), the correlation of the information is decided, as described with reference to  FIG. 4 , on the basis of the received personal information, so that the optimum push information is selected (at Step S 202 ) from the decision.  
         [0074]     For the correlation of the information, reference is made to the information correlating database  22 , and the selection of the push information is made on the basis of the category registered in the information database  21 . Especially the selection of the push information contains the case of collecting it from a server (on the network) other than the information database  21 . Therefore, the collection of the push information means the operation to collect it from the information source on the network including the information database  21  (at Step S 203 ).  
         [0075]     The push information thus collected is transmitted to client  1  that demanded (requested) it.  
         [0076]     Here will be described the display transitions of the client  1 .  FIGS. 7A  to  7 F are diagrams showing display examples, as transited in response to the push demand, on the client side. Where a game is being played online or offline, for example, at the client  1  (as referred to  FIG. 7A ), the screen saver is started (as referred to  FIG. 7B ) if the idling continues for a constant time. At this time, the game is switched to the background.  
         [0077]     After this, there is displayed on the display screen the push information which is serviced from the push server  2  (as referred to  FIG. 7C ). Specifically, it is the birthday of the player, and there is displayed the message “Happy Birthday to You! We Present You Item X.” 
         [0078]     This Item X is an information beneficial information if it can be utilized in the game being played. Here, an explanation icon  12   a  can be operated to receive an explanation on the use of Item X from the display (which may contain the sound or may adopt computer graphics).  
         [0079]     Subsequently, it is also possible to display a next push information. A plurality of push informations may arrive because the push information is selected from the personal information. The manner how to display the push information may be exemplified by switching the screens sequentially or by arranging the plurality of push informations on the common screen.  
         [0080]     It is assumed that the client has a promise of a date and that its plan is scheduled. If this case matches the condition of  FIG. 4C , for example, there is push-distributed and displayed on the screen a restaurant guide “Today, at Restaurant Y of Shibuya, Cakes Are Served to Your Fill at \1,000 for 15:00-16:00.” 
         [0081]     Here, it is possible to display the location of restaurant Y, and its menu by operating a map icon  12   b  to receive the explanation from the display (which may contain the sound or may adopt computer graphics). Here, the weather forecast cannot be displayed, but a weather mark may be displayed or a weather information may be displayed by the multiple displays.  
         [0082]     When the push display of the presentation and the restaurant guide is thus ended, the screen saver is displayed again (as referred to  FIG. 7E ) while the operation of the player is absent. In response to the operation input of the player, moreover, the screen saver ends, and the original game screen is restored (as referred to  FIG. 7F ).  
         [0083]     Here will be briefly described the construction of the game terminal  1 .  FIG. 8  is a block diagram showing one construction example of the client  1  according to this embodiment. The client  1  is constructed, as shown in  FIG. 8 , by connecting with an internal bus  10  a CPU  14 , a ROM  15 , a RAM  16 , the recording medium  11 , an image processing unit  17 , a sound processing unit  18 , the keypad  13 , the display  12 , a communication control unit  19  and so on.  
         [0084]     The internal bus  10  is a line for transmitting the address signal or data in the system. The CPU  14  the operations of the client terminal itself as a whole according to the various programs recording in the recording medium  11 . The ROM  15  is stored with programs such as the push demanding program or the game program for activating the applications, a variety of parameters and so on.  
         [0085]     The RAM  16  is a memory to be used as the work area at the time of executing the various programs. The recording medium  11  may be used, although already described, for storing new programs or data from the network through a line  20  connected with the communication control unit  19 . The image processing unit  17  administers the computer graphics processing or the like at the time of making the push information display, the Web page display, the game execution, the comics display and so on. The sound processing unit  18  administers the voice processing or the like at the time of making the push information output, the Web page output, the game execution, the music output and so on.
