A process of arranging and setting an object (an object composed of a primitive such as a free-form surface or a subdivision surface) in the object space is performed.

  Here, the object space is a virtual space and includes both a two-dimensional space and a three-dimensional space. The two-dimensional space is a space in which an object is arranged at, for example, two-dimensional coordinates (X, Y), and the three-dimensional space is a space in which an object is arranged at, for example, three-dimensional coordinates (X, Y, Z). is there.

  When displaying a plurality of other users, the display control unit 116 displays the information of the plurality of other users according to the order received from the server.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. The image generated by the drawing unit 120 may be a so-called two-dimensional image or a so-called three-dimensional image.

  When a two-dimensional image is generated, an image viewed from the side is generated. For example, a priority is set for each object (sprite), and rendering is performed in order from an object having a lower priority. When objects overlap, an object with a high priority is drawn on an object with a low priority.

When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ) Is input, and vertex processing (shading by a vertex shader) is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary.

  In the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate transformation, for example, world coordinate transformation, visual field transformation (camera coordinate transformation), clipping processing, perspective transformation (projection transformation) ), Geometry processing such as viewport conversion is performed, and based on the processing result, the vertex data given to the vertex group constituting the object is changed (updated or adjusted).

  Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to a drawing buffer (a buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  Note that the drawing unit 120 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, when generating a three-dimensional image, the virtual camera position (X, Y, Z) or rotation angle (for example, from the positive direction of each of the X, Y, and Z axes) in the world coordinate system is used. (Rotation angle when turning clockwise) is controlled. In short, processing for controlling the viewpoint position, the line-of-sight direction, and the angle of view is performed. Further, the virtual camera control unit may rotate the virtual camera at a predetermined rotation angle. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position or rotation angle of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  For example, when an object (for example, a player character) is photographed from behind using a virtual camera, the position of the virtual camera and the orientation of the virtual camera are controlled so that the virtual camera follows changes in the position and orientation of the object. In this case, the virtual camera can be controlled based on information such as the position, orientation, or speed of the object obtained by the movement / motion processing unit 112. Alternatively, the virtual camera may be set in a predetermined direction or may be controlled to move along a predetermined movement route. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or orientation of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The vertex processing and pixel processing are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

  The drawing unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. The object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the object data storage unit. The

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit of the storage unit 170 using the texture coordinates set (given) to the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which Z values (depth information) of drawing pixels are stored. . That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value).

  The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  The storage unit 270 serves as a work area for the processing unit 200, the communication unit 296, and the like, and its function can be realized by a RAM (VRAM) or the like.

  The storage unit (for example, database) 260 stores user information 261 for each of a plurality of users participating in the network system of the present embodiment. For example, the storage unit 260 associates the user identification information (user identification number) of each of the plurality of users with the server 20, and the terminal identification information (identification number) of the terminal 10 for accessing the terminal 10 used by the user. The “user name” of the user and the “destination information” of the terminal 10 (IP address, mail address, port number, MAC address, telephone number, etc.) are stored.

  For example, the storage unit 260 prepares a user table for each user, and stores user information (user identification information) of other users associated with the user.

  The storage unit 260 stores, for each user, an access history 262 (access transmission history, access reception history) between the user and other users associated with the user.

  The information storage medium 280 (computer-readable medium) stores programs, data, and the like, and functions as an optical disk (CD, DVD), magneto-optical disk (MO), magnetic disk, hard disk, and magnetic tape. Alternatively, it can be realized by a memory (ROM). The processing unit 200 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 280. That is, the information storage medium 280 stores a program for causing a computer to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit).

  The communication unit 296 performs various controls for communicating with the outside (for example, a terminal, another server, or another network system), and functions as hardware such as various processors or communication ASICs. Or by a program.

  The processing unit 200 (processor) performs a given process based on a program or the like stored in the information storage medium 280. Specifically, a given service is provided in response to a request from the terminal.

  The processing unit 200 performs various processes using the main storage unit 272 in the storage unit 270 as a work area. The functions of the processing unit 200 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs.

  In particular, the server processing unit 200 according to the present embodiment includes a network setting unit 210, a communication control unit 211, a setting unit 212, a release unit 213, a determination unit 214, a parameter control unit 215, and an order control unit 216. Note that some of these may be omitted.

  The network setting unit 210 acquires user identification information, terminal identification information, and the like from the terminal 10 and stores the user information 261 in the database 260 in association with the acquired user identification information and terminal identification information. The network setting unit 210 performs processing for referring to, updating (changing), and deleting the user information of the user based on the user identification information and the terminal identification information.

  The communication control unit 211 performs processing for transmitting and receiving data to and from the terminal 10 via the network. That is, the communication control unit 211 performs processing of transmitting information (for example, “user name”) of another user associated with the user to the user terminal based on a request from the user terminal. Moreover, the communication control part 211 performs the process which transmits the determination result of the determination part 215 to a user's terminal and another user's terminal. Further, the communication control unit 211 performs a process of transmitting given parameters (for example, transparency, transparency parameters, reduction ratio, etc.) to the user terminal. Moreover, the communication control part 211 performs the process which transmits the information and order of several other users linked | related with the said user to the said user's terminal based on the request | requirement from a user's terminal.

  Based on a request from the user's terminal, the setting unit 212 performs a process of setting an association between the user and another user under registration conditions. For example, in the storage unit 260, the user identification information of the user is associated with the user identification information of another user.

  In addition, the setting unit 212 performs a process of setting association cancellation prohibition information between the user and another user based on a request from the user's terminal. For example, a process of setting the release prohibition flag for other users associated with the user to 1 is performed.

  The canceling unit 213 performs processing for canceling the association between the user and another user based on a request from the user's terminal. Moreover, the cancellation | release part 213 exceeds every 1st predetermined period from the latest access time in a user and the other user linked | related with the said user for every user, and when the 2nd predetermined period passes, Regardless of the request from the user's terminal, a process of releasing the association between the user and another user is performed.

However, when the cancellation prohibition information for the association between the user and another user is set, the canceling unit 213 has passed the second predetermined period from the latest access time between the user and the other user. Even so, control is performed so as not to release the association between the user and other users. For example, when the release prohibition flag for another user associated with the user is set to 1, the second predetermined period has elapsed since the latest access time between the user and the other user. Even if there is, control is performed so as not to release the association between the user and other users.

  The determination unit 214 determines, for each user, whether or not the user and another user have a predetermined relationship (separate relationship). For example, the determination unit 214 determines, for each user, whether the user and another user have a predetermined relationship (distant relationship) in a predetermined cycle (for example, every day, every hour, frame update unit). .

  The determination unit 214 determines, for each user, whether or not the first predetermined period has elapsed since the latest access time between the user and another user associated with the user. When the predetermined period of time has elapsed, it is determined that the user and the other user have a predetermined relationship (separate relationship), and when the first predetermined period has not elapsed since the latest access time, It is determined that the user and the other user are not in a predetermined relationship.

  If the determination unit 214 determines that the user and the other user have a predetermined relationship, the user and the other user have a predetermined relationship until both the user and the other user are accessed. Judge that there is.

  When the determination unit 214 determines that the user and another user have a predetermined relationship, the user and the other user have a predetermined relationship until the number of accesses between the user and the other user reaches a predetermined number. Judge that there is.

  The parameter control unit 215 controls, for each user, given parameters (for example, transparency, transparency parameters, reduction ratio, etc.) for other users associated with the user. For example, the parameter control unit 215 performs a process of changing a given parameter with time.

  The parameter control unit 215 performs a process of lowering a given parameter as time passes until there is an access between the user and another user. When there is an access between the user and another user, the number of accesses Depending on, a process for increasing a given parameter may be performed. In addition, the parameter control unit 215 performs a process of decreasing a given parameter as time passes until a user accesses another user or another user accesses the user. When there is an access to the user or an access to the user from another user, a process for increasing a given parameter may be performed.

  When there are a plurality of other users associated with the user, the order control unit 217 determines the plurality of other users based on the elapsed time from the most recent access time between the user and the other users. Process to determine the order.

3. Friend List (1) Outline The terminal 10 of the network system according to the present embodiment can perform game processing by moving / moving a user's player character existing in the game space based on input information of a user who operates the terminal 10. It is a system that can.

  In this embodiment, the user (user A) can access the server 20 using the terminal 10 to refer to the game data of the user (for example, user B) or transmit a message. That is, according to the network system of the present embodiment, a user can communicate with other users using the terminal 10.

  In particular, the server 20 of the network system according to the present embodiment prepares a friend list for each of a plurality of users participating in the network system, and registers other users for communication in the friend list of each user. Provides services that enable smooth communication between users.

  That is, the network system according to the present embodiment enables users having specific relationships such as friends and acquaintances to smoothly communicate with each other by registering each other's user information in the friend list. .

(2) Display of friend list In the network system of the present embodiment, a friend list is set for each of a plurality of users who operate the terminals 10 participating in the network system.

  The server 20 of this embodiment manages each user's friend list, and performs the process which transmits the user's friend list according to the request | requirement from the terminal 10 which a user operates. For example, when the terminal 10 starts the game, the terminal 10 accesses the server 20 to request the latest friend list, and the server 20 performs processing for transmitting the latest friend to the terminal 10.

  For example, when the storage unit 260 of the server 20 prepares a user table for each user, the server 20 stores a user name, a terminal name, and the like corresponding to the user identification information of the user C from the user table of the user A. The process of acquiring the information of the user C and transmitting the acquired information to the terminal 10A of the user A is performed.

  And in this embodiment, the process which displays a friend list on the display part 160 of a user's terminal 10 is performed. For example, as shown in FIG. 4, user information such as user B, user C, and user D (for example, “user name”, “terminal name”, etc.) is displayed on the display unit of user A's terminal 10A. .

  Furthermore, in this embodiment, as shown in FIG. 5, the detailed content 50 of the user registered in the friend list can be displayed. For example, when the selection of any one of a plurality of users registered in the friend list is accepted, as shown in FIG. 5, the user name of the selected user, the terminal name used by the user, Birthday, number of presents (number of times of receiving specific game data from user B), date of receiving a present from user (user C) (latest date of receiving specific game data from user C), user (user The portrait 50 of C) is displayed.

  In particular, the terminal 10 according to the present embodiment performs processing for displaying a friend list when communicating with a user registered in the friend list. For example, when a message is transmitted to a user registered in the friend list, the friend list is displayed when a destination user is selected. That is, the terminal 10 of this embodiment transmits a request for transmitting a message to the server 20 to the user selected by displaying the friend list.

  In addition, the terminal 10 of the present embodiment can receive game data of a user who operates another terminal 10 registered in the friend list, and can perform game processing in the same game space as the other terminal 10. In such a case, the terminal 10 of the present embodiment performs a process of displaying a friend list as a selection screen for accepting selection of which user's game data to play the game.

  That is, the terminal 10 according to the present embodiment performs a process of displaying a friend list when accessing another user.

(3) Association The server 20 of the present embodiment registers the other user in the friend list of one user and the friend list of the other user at the stage where the agreement between the one user and the other user is obtained. A process of registering one user is performed. That is, in this embodiment, the process which associates one user and the other user and establishes a friend relationship is performed.

  For example, in the present embodiment, when the server 20 receives a friend list registration request from one terminal 10A to the other terminal 10B, the server 20 first registers the friend list from the terminal 10A in the terminal 10B. Process to send the request.

  Then, when the server 20 receives permission information for the friend list registration request of the terminal 10A from the terminal 10B, the server 20 registers the user B in the friend list of the user A of the terminal 10A and also adds it to the friend list of the user B. A process of registering user A is performed.

  More specifically, for example, in the storage unit 260, when a table is set for each user, the user identification information of the user B is registered (inserted) in the user table of the user A, and the user table of the user B is registered. By registering the user identification information of user A, the association between user A and user B is set.

(4) Cancellation of association In the present embodiment, processing for canceling the association between a user and another user is performed based on the input information of the user.

  More specifically, the terminal A performs a process of displaying the friend list of the user A and receiving selection of another user to be deleted. For example, it is assumed that the user C is selected when the friend list of the user A is displayed. Then, the terminal 10 </ b> A performs processing for transmitting the friend relationship cancellation request of the user C to the server 20. And when the server 20 receives the friend relationship cancellation request from the terminal 10A, the server 20 deletes the user C from the friend list of the user A and deletes the user A from the friend list of the user C. A process of canceling the association with another user is performed.

  More specifically, for example, when a table is set for each user in the storage unit 260, a process for deleting the user identification information of the user C from the user table of the user A is performed, and the user table of the user C is performed. By deleting the user identification information of the user A from the user A, the process of releasing the association between the user A and the user C is performed.

4). Automatic cancellation of association (1) Outline As described above, the network system of the present embodiment aims at communication between a plurality of users. However, for example, user registration in the friend list can be performed psychologically, but deleting a alienated user from the friend list is uncomfortable for the user.

  Therefore, in the network system according to the present embodiment, based on the access history between a plurality of users registered in the friend list, mutual access is made from each user's friend list between users who do not have mutual access for a long time. Processing to automatically delete users who have not been in the long term. That is, the network system of this embodiment can release the connection between the user and another user without feeling a sense of resistance.

  As described above, in the network system according to the present embodiment, the user is automatically deleted from the friend list between users who do not access each other for a long period of time regardless of the user's operation. Therefore, in the present embodiment, processing of displaying information of a user who is becoming estranged (user name, portrait, etc.) in a translucent manner is performed in advance. For example, when it is determined that the users A and C are in a distant relationship (an example of a predetermined relationship), the information on the user C is translucent as shown in FIGS. Processing to display. In this way, the user A can easily grasp the user who is becoming estranged.

  This translucent display also includes the meaning that the friend relationship will be canceled in the future. Therefore, if the user A does not want to cancel the friend relationship with the user C, the user A Can motivate user C to actively communicate. Details will be described below.

(2) Access History In this embodiment, the server 20 manages the access history of each user who participates in the network system. That is, for each user participating in the network system, the server 20 performs processing for leaving a record that the user has accessed another user and a record that has been accessed by another user in the storage unit 260 of the server.

  For example, when the terminal A of the user A accesses the server 20 and the user A makes a message transmission request to the user B, or the user A makes a game data request for the user B, the user A Assuming that access is transmitted to B, an access transmission history is left.

  More specifically, the server 20 includes other user names and transmission times when user A transmits data to other users, and other user names when user A requests game data from other users. The process of writing the request time and the other user name and the reference time when the user A refers to the game data to the other user as the access transmission history to the access transmission history table of the storage unit 260 is performed. The storage unit 260 prepares an access transmission history table for each user.

  FIG. 8 is an example of the access transmission history of the user A at 00:00 on February 15, 2009. For example, as the latest access transmission, a history that user A accessed user B at “13:50 on February 14, 2009” remains.

  In addition, the server 20 receives a message from another user (any user such as users B and C) from the terminal A of the user A, or when the game data is requested, the user A As a result, the access reception history is stored.

  More specifically, when the server 20 receives data from another user for the user A, the other user name and transmission time, and when the user A requests game data from the other user Processing for writing other user name and request time, and other user name and reference time when user A refers to game data from another user to the access reception history table of the storage unit 260 as an access reception history Do. The storage unit 260 prepares an access reception history table for each user.

  FIG. 9 is an example of an access reception history for the user A at 00:00 on February 15, 2009. For example, as the latest access reception, there is a history that user A has been accessed by user D at “11:20 on February 13, 2009”.

  Note that the terminal 10 of the present embodiment performs a process of receiving this access reception history from the server 20 and displaying it on the display unit 160 of the terminal 10. FIG. 10 is an example of an access reception history for the user A displayed on the display unit 160 of the terminal 10A. For example, the display unit of the terminal 10A displays the user name of another user who has accessed the user A and the name of the terminal used by the other user, along with the date and time. For example, the access reception history is displayed so that the most recently accessed history is higher.

  As described above, the server 20 according to the present embodiment manages the access transmission history and the access reception history, and based on the access transmission history and the access reception history, a sparse relationship determination process between a plurality of users, and automatic association cancellation. Processing is in progress.

(3) Distant relationship determination processing For each user, the server 20 of the present embodiment performs one month (an example of a first predetermined period) from the latest access time point between the user and another user associated with the user. If the first predetermined period has elapsed from the latest access time, it is determined that the user and the other user are in a sparse relationship, and one month has elapsed from the latest access time. If not, a process of determining that the user and the other user are not in a estranged relationship is performed.

  That is, for each user, the server 20 of the present embodiment refers to the access transmission history and access reception history with other users registered in the user's friend list. When one month and one other user have passed one month (an example of the first predetermined period) from the latest access point, the one user and the other user are in a estranged relationship. Is determined.

  For example, as shown in FIG. 8, during the processing of the server 20 (February 15, 2009, 00:00), access transmission with the user C associated with the user A (having a friend relationship with the user A) Looking at the history, the latest access time point for the user A to the user C is “10:20 on January 14, 2009”, and one month or more has passed since this latest time point. Further, as shown in FIG. 9, when the access reception history with the user C associated with the user A at the time of processing of the server 20 (February 15, 2009 00:00), Thus, the latest time point accessed by the user C is “2009, January 14, 21:40”, and one month or more has passed since this latest time point. That is, the user A and the user C do not have bidirectional access for one month or longer.

  As described above, when one month or more has passed since the latest access time between the user A and the user C, the server 20 of the present embodiment determines that the user A and the user C are in a sparse relationship. .

  On the other hand, the server 20 of this embodiment refers to the access transmission history and the access reception history with other users registered in the user's friend list for each user, and in one user and the other user, When one month (an example of the first predetermined period) has not elapsed since the latest access point, it is determined that one user and the other user are not in a sparse relationship.

  For example, as shown in FIG. 8, when the access transmission history with the user B associated with the user A (having a friend relationship with the user A) is viewed, the latest access time point that the user A performed on the user B Is “February 14, 2009 13:50”, and more than one month has not passed since this latest time point. As described above, when one month or more has not passed since the latest time point of access by the user A and the user B (“13:50 on February 14, 2009”), the server 20 of the present embodiment It is determined that the user A and the user B are not in a remote relationship.

  The server 20 according to the present embodiment is configured to identify information indicating that the users A and C are remote from the terminals 10A and 10C of the user C, which are determined to be in a remote relationship between the users A and C ( Processing for transmitting a sparse flag = 1) is performed. For example, when there is an access to the server 20 from the terminal 10A, the server 20 transmits a sparse flag = 1 in association with the user identification information of the user C. Similarly, when there is an access from the terminal 10C to the server 20, the server 20 transmits a sparse flag = 1 in association with the user identification information of the user A.

  On the other hand, the server 20 of the present embodiment specifies information indicating that the user A and the terminal B of the user A, which are determined not to have a sparse relationship between the users A and B, are not sparse between the users A and B ( Processing for transmitting a sparse flag = 0) is performed. For example, when the server 20 is accessed from the terminal 10 </ b> A, the server 20 transmits a sparse flag = 0 in association with the user identification information of the user B. Similarly, when the terminal 20B accesses the server 20, the server 20 transmits a sparse flag = 0 in association with the user identification information of the user A.

  And in each terminal, the information of the user whose distant flag = 1 is indicated in the friend list displayed on the display unit 160 (the information of the user whose distant flag corresponding to the user identification information is 1) is displayed in a translucent manner. And the process of displaying the information of the user for whom the sparse flag = 0 is indicated (the information of the user whose sparse flag corresponding to the user identification information is 1) in an opaque manner. For example, when the terminal 10A receives the sparse flag = 1 for the user C, as shown in FIGS. 6 and 7, a process of displaying the user C in a translucent manner is performed.

  In this way, the user A who operates the terminal A can recognize that he / she is away from the user C instantly. Then, in order to prevent the friend relationship with the user C from being canceled, the user A can give the user C a motivation to try to communicate with the user C.

(4) Automatic Association Cancellation Processing The server 20 of this embodiment performs processing for automatically canceling the association between a user and another user.

  For each user, the server 20 according to the present embodiment, when two months (an example of a second predetermined period) have passed since the latest access time between the user and another user associated with the user, Regardless of the request from the user's terminal, a process for releasing the association between the user and another user is performed.

  That is, for each user, the server 20 of the present embodiment refers to the access transmission history and access reception history with other users registered in the user's friend list. When one user and the other user have passed two months (an example of the second predetermined period) from the latest access point, the association between the one user and the other user is released. Process.

  For example, as shown in FIG. 11, during the processing of the server 20 (00:00 on March 15, 2009), access transmission with the user C associated with the user A (having a friend relationship with the user A) Looking at the history, the latest access time point for the user A to the user C is “10:20 on January 14, 2009”, and two or more months have passed since this latest time point. In addition, as shown in FIG. 12, when the server 20 processes (00:00 on March 15, 2009), the access reception history with the user C associated with the user A is Thus, the latest time point accessed by the user C is “21:40 on January 14, 2009”, and two months or more have passed since this latest time point. That is, the user A and the user C do not have bidirectional access for two months or more.

  As described above, when two months or more have passed since the latest access time between the user A and the user C, the server 20 of the present embodiment performs a process of releasing the association between the user A and the user C. . That is, in order to cancel the friend relationship between the user A and the user C, a process of deleting the user A (or the user C) from both friend lists is performed.

  More specifically, the process of deleting the user identification information of the user C from the user table of the user A is performed, and the user identification information of the user A is deleted from the user table of the user C. Perform the process of releasing the association.

  For example, when the terminal 10A accesses the server 20, the server 20 performs a process of transmitting a new friend list from which the user C is deleted to the terminal 10A. And in terminal 10A, the process which displays the new friend list (friend list from which user C was deleted) received from the server 20 on a display part is performed.

  Similarly, when there is an access to the server 20 from the terminal 10C, the server 20 performs a process of transmitting a new friend list from which the user A is deleted to the terminal 10C. And in terminal 10C, the process which displays the new friend list (friend list from which user A was deleted) received from the server 20 on a display part is performed.

  As described above, if the users A and C do not access both for a long period of time, the server 20 automatically deletes the user who has become estranged from the friend list regardless of the operations of the users A and C. Become. Therefore, when the users A and C are in a estranged state, the user has no psychological burden and can be disconnected from each other.

(5) Exception processing The server 20 according to the present embodiment, when the cancellation prohibition information (release prohibition flag = 1) for associating a user with another user is set, Even when two months (an example of the second predetermined period) have elapsed since the access point, the association between the user and other users is not released.

  For example, it is assumed that the user A and the user E have a relationship such that communication is performed only once a year via the network. However, there may be a case where the user A or the user E does not want to cancel the friend relationship just because the user A or the user E becomes estranged.

In order to cope with such a situation, in the network system of the present embodiment, a release prohibition flag is provided for each user registered in the friend list, and when the release prohibition flag = 0, the user and other users When two months (an example of the second predetermined period) have passed since the most recent access time in, perform the process of releasing the association between the user and other users,
When the release prohibition flag = 1, the association between the user and the other user is not released when two months (an example of the second predetermined period) have passed since the latest access time between the user and the other user. To control.

  FIG. 13 is an example of the display unit 160 of the terminal 10 </ b> A that displays a check box for prohibiting cancellation in association with each user registered in the friend list of the user A.

  For example, when the terminal 10 </ b> A accepts a check for prohibition of cancellation by the user E based on input information from the user A, the cancellation prohibition flag corresponding to the user E is set to 1.

  Further, since the terminal 10 accepts the check boxes for the prohibition of cancellation of the users B, C, D, and F based on the input information from the user A, it corresponds to each of the users B, C, D, and F. Set the release prohibition flag to 0.

  When the terminal 10 </ b> A accesses the server 20, the terminal 10 </ b> A performs processing for transmitting the value (1 or 0) of the release prohibition flag in association with the user identification information of each user registered in the friend list. The server 20 performs processing for setting the received release prohibition flag as information of each user in the friend list of the user A.

  In the network system of the present embodiment, the user E registered in the friend list of the user A has the user A registered in the friend list of the user E. Therefore, when the server 20 receives the release prohibition flag = 1 of the user E in the friend list of the user A, the server 20 performs processing for setting the release prohibition flag of the user A = 1 in the friend list of the user E. Do.

(6) Translucent display The server 20 of the present embodiment adjusts the transparency according to the passage of time in order to show the degree of estrangement between a plurality of users determined to be in a sparse relationship, Processing to send to the terminal.

  For example, as illustrated in FIG. 14, the server 20 according to the present embodiment has a time T2 (distant) after one month (first predetermined period) from the time T1 when the latest access between the user A and the user C has occurred. At the start time), the transparency is set to 20%, and the process of increasing the transparency as the time elapses (the process of increasing the transparency) is performed from the time T2. That is, the transparency is adjusted so as to be visually transparent. For example, as shown in FIG. 15A, the transparency is changed from time T2 to time T3.

  For example, when the server 20 accesses the server 20 from the terminal 10A, the server 20 transmits the transparency when the user A accesses the server 20 from the terminal 10A together with the user C and the sparse flag = 1. Do. Similarly, when the server 20 is accessed from the terminal 10C, the server 20 performs a process of transmitting the transparency when the terminal 10C accesses the server 20 together with the remote flag = 1 between the user C and the user A = 1. Do.

  Then, in the terminal 10A, based on the transparency received from the server 20, the information of the user C with the sparse flag = 1 is displayed in a translucent manner. That is, the information of the user with the sparse flag = 0 (for example, the user B) is displayed in an opaque manner, and the information of the user C with the sparse flag = 1 is displayed in a translucent manner based on the received transparency.

  In the present embodiment, the transparency is set to 0 when the user A accesses the user C during the remote period (from the time T2 to the time T3) or when the user C accesses the user A. Return to% (completely opaque). For example, as shown in FIG. 15B, when there is an access from the user A to the user C at the time Q1 before the second predetermined period elapses from the time T1, for example, the access is the latest. Therefore, it is determined that there is no sparse relationship, and the transparency is returned to 0%. For example, on the display unit 160 of the terminal 10A, as shown in FIGS. 4 and 5 again, the information on the user C is displayed in an opaque manner, so that the user A has canceled the estranged relationship with the user C. I can recognize that.

  Next, details of the translucent display process of the present embodiment will be described. First, when the semi-transparent display of the fonts (characters) shown in FIGS. 6 and 7 is performed, the font color is changed so as to approach the background color as the transparency increases. Here, when the parameter regarding transparency is α (0 ≦ α ≦ 1, α = 0 is completely transparent and α = 1 is completely opaque), α is calculated by α = (100−transparency) ÷ 100. When the background color C1 and the font color C2 are used, the font color C to be finally output can be obtained by the following equation (A).

C = C1 × (1−α) + C2 × α (A)
Further, when the polygon such as the portrait in FIG. 7 is displayed semi-transparently, a process of changing the polygon color so as to approach the background color as the transparency increases is performed. Here, assuming that the polygon color is C3, the composite color C ′ of the polygon to be finally output can be obtained by the following equation (B).

C ′ = C1 ra (1−α) + C3 × α (B)
Then, each terminal 10 performs a process of displaying the user information registered in the friend list based on the obtained composite color. Note that the server side may obtain these composite colors and transmit the composite colors from the server 20 to each terminal 10.

5). Flowchart Next, the processing of the server 20 will be described with reference to FIG. This process is performed for each user based on other users associated with the user. Further, this process is performed in a predetermined cycle (for example, in units of one day). For example, the process is started at 00:00 every day. The example of FIG. 16 is an example of a process based on the user B associated with the user A.

  First, it is determined whether or not a month (first predetermined period) has passed since a specific point in time when user A and user B had the latest access (step S11). If it is determined that one month has passed since the specific point of access (Y in Step S11), it is determined whether two months have passed since the specific point in time when the latest access was made between the user A and the user B ( Step S12). If it is determined that one month has not passed since the specific time when user A and user B had the latest access (N in step S11), the process is terminated.

  If it is determined that two months have passed since the specific point in time when user A and user B had the most recent access (Y in step S12), whether release prohibition flag = 1 is set for user A and user B It is determined whether or not (step S13).

  If the cancellation prohibition flag = 1 is not set for user A and user B (N in step S13), a process for canceling the association between user A and user B is performed (step S14). Exit.

  If it is determined that two months have not elapsed since the specific time when user A and user B had the latest access (N in step S12), release prohibition flag = 1 is set for user A and user B. If it is set (Y in step S13), a process for determining the transparency is performed based on the elapsed time from the specific time (step S15), and the process is terminated.

6). Application examples (1) Expression of estrangement The server 20 of the present embodiment shows a reduction rate (magnification) (given in accordance with the passage of time) in order to indicate the degree of estrangement among a plurality of users determined to be in estrangement. May be adjusted to transmit the reduction ratio to each terminal.

  For example, as illustrated in FIG. 14, the server 20 according to the present embodiment has a time T2 (distant) after one month (first predetermined period) from the time T1 when the latest access between the user A and the user C has occurred. From the start time), a process of reducing the reduction rate is performed as time passes.

  For example, when the server 20 is accessed from the terminal 10A, the server 20 transmits the reduction rate at the time when the user A accesses the server 20 from the terminal 10A together with the user C and the sparse flag = 1. I do. Similarly, when the server 20 is accessed from the terminal 10C, the server 20 transmits a reduction rate at the time when the terminal 10C accesses the server 20 together with the sparse flag = 1 between the user C and the user A = 1. I do.

  Then, the terminal 10A performs a process of reducing and displaying the information of the user C with the sparse flag = 1 based on the reduction rate received from the server 20. In other words, the font size of the user with the sparse flag = 0 (for example, the user B) is displayed at the reference size 1, and the font size of the information of the user C with the sparse flag = 1 is reduced to the reference size 1. A process of displaying a size multiplied by a rate (for example, 0.8) is performed.

  In the present embodiment, when the user A accesses the user C during the sparse period (from time T2 to time T3), or when the user C accesses the user A, the reduction rate is It will return to the standard size.

(2) Dissociation cancellation In this embodiment, when it is determined that the user and the other user are in a distant relationship, the user and the other user and the other user are accessed until both the user and the other user are accessed. May be determined to be in a estranged relationship.

  For example, as shown in FIG. 17 (A), the server 20 of this embodiment is configured such that T2 has passed one month (first predetermined period) from the time T1 when the latest access was made between the user A and the user C. Transparency is set to 20% at the time (at the start of estrangement), and processing for increasing the transparency is performed as time passes from time T2.

  Then, the server 20 is still in a sparse relationship when there is an access from the user A to the user C at the time Q1 before two months (second predetermined period) elapse from the time T1. And lower the transparency. For example, a process for setting the transparency to 20% is performed.

  Then, when there is a user A access from user C at time Q2 before two months (second predetermined period) elapse from time T1, the server 20 determines that there is no sparse relationship. That is, the process of returning the transparency to 0% at the time of Q2 after the estranged relationship is resolved.

  In this way, the sparse state will continue unless both parties try to access, thus providing a motivation to communicate with each other. In addition, the user can visually recognize how the distant relationship is canceled because the transparency is lowered by access from one to the other.

  Furthermore, in this embodiment, when it is determined that the user and the other user are in a estranged relationship, the user and the other user are estranged until the number of accesses between the user and the other user reaches a predetermined number. You may determine with a relationship.

  For example, it may be determined that the user and the other user are in a estranged relationship until the total number of accesses from the user A to the user C and the access count of the user C to the user A reaches three times.

  For example, as shown in FIG. 17B, the server 20 of the present embodiment is configured such that T2 has passed one month (first predetermined period) from the time T1 when the latest access has been made between the user A and the user C. Set the transparency to 20% at the point in time (at the start of estrangement) Then, from the time point T2, processing for increasing the transparency is performed as time elapses.

  Then, when there is a first access (access from the user A to the user C) at the time point Q1 before two months (second predetermined period) elapse from the time point T1, the server 20 has a sparse relationship. Is determined to continue, and the process of lowering transparency is performed. For example, the transparency is set to 30%.

  Further, the server 20 is in a sparse relationship when there is a second access (access from the user A to the user C) at the time Q2 before two months (second predetermined period) elapse from the time T1. Is determined to continue, and the transparency is further lowered. For example, the transparency is set to 20%.

  If the server 20 has made a third access (access from the user C to the user A) at the time Q3 before two months (second predetermined period) elapse from the time T1, the server 20 is not in a remote relationship. judge. That is, processing for returning the transparency to 0% at the time of Q3 is performed.

  In this way, it is possible to give a motivation to frequently access users who are in a estranged relationship. In addition, the transparency of the server 20 decreases according to the number of accesses between the user and other users until the number of accesses reaches a predetermined number, so that the user visually recognizes that the distant relationship is resolved. Can do.

(4) Sorting When there are a plurality of other users associated with the user, the server 20 according to the present embodiment has a plurality of servers based on the elapsed time from the latest access time between the user and the other users. You may make it perform the process which determines the order of another user. For example, the other users are rearranged in the order in which the elapsed time from the latest access time of the user and the other users is short.

  The server 20 according to the present embodiment performs processing for transmitting a plurality of other user information associated with the user and the determined order to the user terminal based on a request from the user terminal. And the terminal 10 performs the process which receives the information and order of several other users from the server 20, and displays several other users' information according to order.

  For example, as shown in FIG. 18, when displaying the friend list in which a plurality of users are registered, the display unit 160 of the terminal 10 </ b> A of the user A displays each user according to the order received from the server 20. . For example, the user (user D) who accesses the latest in the friend list is displayed on the top. In this way, the estranged user is inevitably displayed at the lower level, so that the user A can instantly understand the degree of estrangement of each user registered in the friend list.

  (5) Further, the present invention may be applied to a network system in which a plurality of terminals generate a communication group (team) composed of a plurality of players in a common game space and play a game among a plurality of teams. In such a case, if a player accesses another player by recruiting or participating in a team, or if a plurality of players play a game with the same team, it is assumed that a plurality of players have accessed each other. It may be left in the access history.
