In the object information table 38, an object ID, an object name, a position latitude, a position longitude, a height, a physical strength value, and a defense value of each quadrant are stored for each object. The terminal IF unit 32 stores information regarding the object determined as described above in the object information table 38. The value of the strength value field is changed by applying a user action.

  The terminal IF unit 32 determines from the current position of the user terminal 9 according to the position information of each user terminal 9 stored in the user information table 37 and the position information of each object stored in the object information table 38. An object determined to be present at a position within the range is specified, and data relating to the object is transmitted to the user terminal 9. The data related to the object includes image data of the object such as a monster image, object ID, object name, position information of the object, physical fitness value, and the like. In the user terminal 9 that has received such data relating to the object, the image of the object is displayed at a position corresponding to the position information of the object on the image of the real environment acquired by the camera function.

  The terminal IF unit 32 receives various data sent from each user terminal 9 in response to a user operation at each user terminal 9. As various data, as described above, data indicating that the object displayed on the image of the real environment on the user terminal 9 has been selected by the user operation, that is, the object selection operation has been executed, and the selection thereof. The target object ID of the target object is included. The various data includes data indicating that one action is selected by a user operation on the user terminal 9, that is, data indicating that an action selection operation is performed, and an action ID of the selected action.

  When the terminal IF unit 32 receives data indicating that the object selection operation has been executed, the terminal IF unit 32 obtains the user ID indicating the transmission source of the data and the object ID of the selected object from the relation information calculation unit 33. Send to. When receiving data indicating that the action selection operation has been executed, the terminal IF unit 32 sends the user ID indicating the transmission source of the data and the action ID of the selected action to the action result generation unit 35.

  Upon receiving the user ID and the object ID from the terminal IF unit 32, the relationship information calculation unit 33 acquires the position of the object indicated by the object ID, and the user terminal 9 indicated by the user ID and the object And the quadrant of the user terminal 9 when viewed from the object is determined. Specifically, the relationship information calculation unit 33 extracts a record in which the user ID sent from the terminal IF unit 32 is set from the user information table 37, and displays the terminal in the selected object ID field of this record. The object ID sent from the IF unit 32 is stored. In addition, the relationship information calculation unit 33 acquires latitude information and longitude information stored in the current position latitude field and the current position longitude field in the extracted record.

  The relationship information calculation unit 33 extracts a record in which the object ID sent from the terminal IF unit 32 is set from the object information table 38 and stores the latitude stored in the position latitude field and the position longitude field of this record Get information, longitude information and height information. The relationship information calculation unit 33 selects the target being selected based on the latitude information, longitude information, and height information acquired from the object information table 38, and the latitude information and longitude information sent from the user information table 37. The distance between the object and the user terminal 9 is calculated. At this time, the height of the user terminal 9 is set to zero, for example.

  Furthermore, the relationship information calculation unit 33 determines the quadrant of the user terminal 9 when viewed from the target object from the latitude information and longitude information of the user terminal 9 and the latitude information and longitude information of the target object. In the present embodiment, any one of the northeast quadrant, the southeast quadrant, the southwest quadrant, and the northwest quadrant is determined as the quadrant of the user terminal 9 when viewed from the object.

  The relationship information calculation unit 33 stores the distance and quadrant obtained in this way in the distance field and quadrant field of the record specified by the user ID in the user information table 37.

  The action selection unit 34 specifies the type of action (attack) that the user terminal 9 can execute on the selected object based on the distance information updated by the relationship information calculation unit 33. Specifically, the action selection unit 34 extracts a record in which the distance calculated by the relationship information calculation unit 33 is equal to or less than the value of the minimum distance field from the action definition table 39, and the action ID and action of this record Get the name.

  The action selection unit 34 stores the acquired action ID in the executable action field of the record specified by the target user ID in the user information table 37. The action selection unit 34 transmits the obtained action ID and action name to the user terminal 9 via the terminal IF unit 32.

  Upon receiving the user ID and the action ID of the selected action from the terminal IF unit 32, the action result generation unit 35 generates result information in which the selected action is applied to the selected object. In the present embodiment, since the game is targeted, the action application effect is a decrease in the stamina value of the monster being selected, and the result information is the remaining stamina value of the monster.

  The action result generation unit 35 uses information on the distance between the user terminal 9 and the object in determining the action application effect. In the present embodiment, the action result generation unit 35 calculates the effect of the action according to the distance between the user terminal 9 and the object, that is, the attack value of the action. The degree of influence of the action on the object should change according to the distance. For example, the action of hitting should be able to do more damage to the object the closer it is to the object. Therefore, also in the present embodiment, the attack value of the action is changed according to the distance in order to bring the virtual action closer to the real world phenomenon. The action result generation unit 35 uses a value obtained by subtracting a value obtained by dividing the acquired distance by a predetermined unit distance (for example, 1000 meters) from 1 as an attack coefficient, and the attack coefficient is acquired from the action definition table 39. A value obtained by multiplying the attack value is calculated as the current attack value. The predetermined unit distance is determined as the maximum distance at which the effect of the action can occur and is held in advance. That is, when the acquired distance is the predetermined unit distance, the attack coefficient is zero, and the attack coefficient is calculated to increase as the acquired distance decreases.

The action result generation unit 35 uses the generated result information (physical fitness value) as the object information table 3.
8 is reflected in the record indicating the object. The action result generation unit 35 transmits information such as the generated result information (physical fitness value) to the user terminal 9 via the terminal IF unit 32. Thereby, on the screen of the user terminal 9, the stamina value which decreased by having performed the action regarding the said monster is displayed. In addition, this embodiment does not limit the display form on the user terminal 9 of such result information. Further, a specific method for generating the result information will be described in detail in the following operation example section.

  The location information management unit 31 of the application server 2 acquires location information (locations U1 and U2) and a user ID from each of the user terminals 9 (# 1) and (# 2) at an arbitrary timing. The position information management unit 31 stores each acquired position information in the current position latitude field and the current position longitude field of the record of the user information table 37 specified by each user ID. In the example of FIG. 6, the current position latitude is set to X5 and the current position longitude is set to Y5 for the user terminal 9 (# 1), and the current position latitude is set to X6 and the current position longitude is set to Y6 for the user terminal 9 (# 2). Is done. In addition, in this embodiment, since the example which does not acquire height information from each user terminal 9 is shown, the height of each user terminal 9 is set to zero.

  On the other hand, the terminal IF unit 32 of the application server 2 that functions as a game server manages an object (hereinafter referred to as a monster). In the example of FIG. 6, the object information about the monsters 51 and 52 located near the user terminals 9 (# 1) and (# 2) is stored in the object information table 38, respectively. As the position information (positions U1 and U2) of the monster as the object information, information on the latitude, longitude, and height of the real world is used. In the example of FIG. 6, in the object information table 38, the position latitude is set to X1, the position longitude is set to Y1, and the height is set to Z1 with respect to the monster 51. Set to Z2.

  The terminal IF unit 32 of the application server 2 uses the position information of the user terminals 9 (# 1) and (# 2) stored in the user information table 37 and the position information of the objects stored in the object information table 38. In response, the monsters 51 and 52 that are determined to exist at positions within a predetermined range from the current positions of the user terminals 9 (# 1) and (# 2) are specified, and the data regarding the monsters 51 and 52 is stored in the user. Transmit to terminals 9 (# 1) and (# 2), respectively. In the example of FIG. 6, monster image data, object ID, object name, object position information, physical fitness value, and the like are sent as data relating to the monsters 51 and 52, respectively. In the user terminal 9 that has received such data regarding the monsters 51 and 52, the monsters 51 and 52 are superimposed and displayed on the image of the real environment acquired by the camera function. In addition, the display form of the monsters 51 and 52 is determined according to the position of each user terminal 9 (# 1) and (# 2) and the position of each monster 51 and 52, for example.

  FIG. 7 is a diagram illustrating an example of a display screen of the user terminal 9 (# 1). In the example of FIG. 7, monsters 51 and 52 are superimposed on the screen 61 of the user terminal 9 (# 1) and displayed on the real world video (image) acquired by the built-in camera function.

The user selects a monster to be attacked from among the displayed monsters 51 and 52 by operating the operation button 62 of the user terminal 9 (# 1) or the touch panel of the screen 61. Here, it is assumed that the monster 51 is selected as an attack target. When the monster 51 is selected and operated as an attack target by the user, the user terminal 9 (# 1) has data indicating that the target selection operation has been executed, a user ID, and a target indicating the selected monster 51. The ID is wirelessly transmitted to the application server 2.

  Hereinafter, an operation example of the application server 2 after the user performs an object selection operation will be described with reference to FIG. FIG. 8 is a flowchart illustrating an operation example of the application server 2.

  As described above, the terminal IF unit 32 of the application server 2 sets the user ID indicating the source of the data and the target ID of the selected monster 51 together with the data indicating that the target selection operation has been executed. Obtained from the terminal 9 (# 1) (S100). The terminal IF unit 32 sends the user ID and the object ID to the related information calculation unit 33.

  The relationship information calculation unit 33 extracts a record in which the user ID sent from the terminal IF unit 32 is set from the user information table 37, and sends it from the terminal IF unit 32 to the selected object ID field of this record. Stored object ID is stored. Subsequently, the relationship information calculation unit 33 acquires latitude information and longitude information stored in the current position latitude field and the current position longitude field in the extracted record. Here, latitude information X5 and longitude information Y5 are acquired as position information of the mobile terminal 9 (# 1).

  The relationship information calculation unit 33 extracts a record in which the object ID sent from the terminal IF unit 32 is set from the object information table 38 and stores the latitude stored in the position latitude field and the position longitude field of this record Get information, longitude information and height information. Here, latitude information X1, longitude information Y1, and height information Z1 are acquired as position information of the monster 51 selected as the attack target in the user terminal 9 (# 1) (S101).

  The relationship information calculation unit 33 sets the height of the user terminal 9 (# 1) to zero, and the latitude information (X1), longitude information (Y1), and height information (Z1) of the monster 51 acquired as described above. From the latitude information (X5), longitude information (Y5), and height information (zero) of the user terminal 9 (# 1), the distance between the monster 51 and the user terminal 9 (# 1) (shown in FIG. 6) Symbol 55) is calculated (S102). Furthermore, the relationship information calculation unit 33 uses the quadrant of the user terminal 9 (# 1) based on the position of the monster 51 as the latitude information (X1) and longitude information (Y1) of the monster 51 and the user terminal 9 (# 1). Determination is made using latitude information (X5) and longitude information (Y5) (S102). Here, the quadrant of the user terminal 9 (# 1) is determined as the northwest quadrant.

  The relationship information calculation unit 33 stores the distance and quadrant obtained in this way in the distance field and quadrant field of the record specified by the user ID in the user information table 37 (S103).

  The action selection unit 34 specifies the type of action (attack) that the user terminal 9 (# 1) can execute on the monster 51 based on the distance information updated by the relationship information calculation unit 33 ( S104). Specifically, the action selection unit 34 extracts a record in which the distance calculated by the relationship information calculation unit 33 is less than or equal to the value of the minimum distance field from the action definition table 39, and the action ID of the extracted record To get. The action selection unit 34 stores the acquired action ID in the executable action field of the record indicating the user terminal 9 (# 1) in the user information table 37, and the action ID and action name thus obtained. Is sent to the user terminal 9 via the terminal IF unit 32 (S104).

When the user terminal 9 (# 1) receives the list of action IDs and action names from the application server 2, the display unit (for example, the action selection unit 65 shown in FIG. 9) selects an action that can be used for the attack of the monster 51. Is displayed on the screen 61. FIG. 9 is a diagram illustrating an example of the action selection unit. The action selection unit 65 displays each action name (throwing a spear, releasing a bow, shooting a gun) received from the application server 2. The user operates the user operation 9 to select and execute a desired action. For example, an action of throwing a spear (action ID = 3 in the example of FIG. 4) is executed. In response to the user operation, the user terminal 9 (# 1) transmits to the application server 2 data indicating that the action selection operation has been executed, an action ID (3) indicating the selected action, and the user ID. .

  In the application server 2, the terminal IF unit 32 receives data indicating that an action selection operation has been performed, an action ID, and a user ID sent from the user terminal (# 1) (S105). When the terminal IF unit 32 receives data indicating that the action selection operation has been executed, the terminal IF unit 32 sends the user ID and the action ID received together with the data to the action result generation unit 35.

  The action result generation unit 35 acquires the selected object ID, distance, and quadrant of the record specified by the user ID sent from the terminal IF unit 32 from the user information table 37. Here, regarding the user terminal 9 (# 1), the object ID indicating the monster 51 is acquired as the selected object ID, and the northwest quadrant is acquired as the quadrant. Here, it is assumed that the acquired distance is 30 (m), and the object ID indicating the monster 51 is “11”.

  Furthermore, the action result generation unit 35 stores the physical strength value of the record specified by the acquired selected object ID from the object information table 38 and the acquired defense value of the quadrant ( The defense value of the northeast quadrant defense value field, the southeast quadrant defense value field, the southwest quadrant defense value field, or the northwest quadrant defense value field) is acquired (S106). Here, according to the example of the object information table 38 shown in FIG. 5, the physical strength value (1000) and the defense value (5) of the northwest quadrant are acquired for the monster 51 (object ID = 11).

  Further, the action result generation unit 35 acquires the attack value of the record specified by the action ID sent from the terminal IF unit 32 from the action definition table 39. Here, according to the example of the action definition table 39 shown in FIG. 4, the attack value (600) of the action of throwing a spear (action ID = 3) is acquired.

  The action result generation unit 35 calculates the effect of the selected action, that is, the attack value of the action, according to the distance (30 (m)) between the user terminal 9 and the object. Specifically, first, the action result generation unit 35 calculates a value obtained by subtracting a value obtained by dividing the acquired distance by a predetermined unit distance (for example, 1000 meters) from 1 as an attack coefficient. The predetermined unit distance is determined as the maximum distance at which the effect of the action can occur and is held in advance. That is, when the acquired distance is the predetermined unit distance, the attack coefficient is zero, and the attack coefficient is calculated to increase as the acquired distance decreases. Here, the attack coefficient is determined by the following equation.

(Attack coefficient) = 1- (30 (m) / 1000 (m)) = 0.97
The action result generation unit 35 calculates a value obtained by multiplying the attack coefficient (0.97) thus calculated by the attack value (600) acquired from the action definition table 39 as the current attack value. Here, the current attack value is determined to be 582 (= 600 × 0.97).

The action result generation unit 35 calculates a value obtained by subtracting the defense value of the target quadrant acquired from the target information table 38 from the current attack value as a value indicating the effect of the current action. Here, since the target quadrant is the northwest quadrant and its defense value is 5, the value indicating the effect of this action is determined to be 577 (= 582-5). When the defense value of the target quadrant is larger than the current attack value, the value indicating the effect of the current action is set to zero.

  The action result generation unit 35 calculates result information by subtracting a value indicating the effect of the current action from the physical fitness value acquired from the object information table 38 (S107). Here, as the result information, the remaining strength value of the monster 51 is calculated as 423 (= 1000-577).

  The action result generation unit 35 updates the physical strength value field of the object information table 38 with the result information calculated in this way (S108). Here, the physical strength value field of the record of the object ID “11” in the object information table 38 shown in FIG. 5 is updated from 1000 to 423. The action result generation unit 35 transmits the generated result information (residual strength value; 423) and the target object ID (11) to the user terminal 9 via the terminal IF unit 32.

  FIG. 10 is a diagram illustrating an example of a screen showing an action result. When the user terminal 9 (# 1) receives the result information (remaining strength value; 423) and the object ID (11) from the application server 2, the user terminal 9 (# 1) displays the result information for the monster 51 indicated by the object ID. . In the example of FIG. 10, the result information is displayed on the result information display unit 66.

  As described above, the operation example of the application server 2 that targets the user terminal 9 (# 1) in the example of FIG. 6 has been described. But it works in the same way. Since the user terminal 9 (# 1) and the user terminal 9 (# 2) have different positions, the distance to the monster 51 and the quadrant from the monster 51 are different from each other. Thereby, the executable action, the effect of the action, and the result information are different between the user terminal 9 (# 1) and the user terminal 9 (# 2). The present embodiment does not prevent different actions from being executed on the same monster 51 at the same timing from the user terminals 9 (# 1) and (# 2). In this case, the action result information from the user terminal 9 (# 1) and the action result information from the user terminal 9 (# 2) are added together and applied to the monster 51.

[Operations and effects in this embodiment]
In the application server 2 in this embodiment, real-world position information such as latitude and longitude is acquired from each user terminal 9 and stored in the user information table 37. Furthermore, in the application server 2, a virtual object that is an appearance of the provided game is generated, and the virtual object is represented by coordinate information indicating the position of the real world such as latitude, longitude, altitude, and the like. The virtual position information, parameter values, and parameter values for each quadrant from the virtual object are determined and stored in the object information table 38.

  In each user terminal 9, data about the virtual object corresponding to the position information of the user terminal 9 is received from the application server 2, and an image acquired by the camera function of the user terminal 9 is displayed on the virtual object. The image to which the image is added is displayed as a game scene using AR.

  In the application server 2, the object ID of the virtual object selected as the attack target among the virtual objects displayed on the screen of the user terminal 9 is acquired, and the distance between the virtual object and the user terminal 9 And the quadrant of the user terminal 9 based on the virtual object is calculated based on the position information stored in the user information table 37 and the object information table 38. Subsequently, actions that can be executed by the user terminal 9 are narrowed down from all actions according to the distance calculated in this way, and a list of the actions is sent to the user terminal 9.

According to this embodiment, the virtual object calculated using values in the real world and the user terminal 9
The action that can be executed is switched according to the distance between the virtual object and the user who selects the action for the virtual object can have a real feeling.

  In the application server 2, the original attack value of the action selected by the user changes according to the distance between the virtual object and the user terminal 9. Furthermore, the defense value of the action from the user terminal 9 to the virtual object changes according to the quadrant of the user terminal 9 from the virtual object.

  Therefore, according to the present embodiment, it is possible to change the effect and result information of the action selected by the user according to the distance and quadrant between the virtual object and the user terminal 9. Thereby, the user who performs an action on the virtual object provided from the application server 2 can feel high reality not only from the display screen using AR but also in the action.

[Modification]
In the above-described embodiment, an example in which the application server 2 provides a game has been described. However, the provided object may not have game characteristics as long as it is a service that additionally presents electronic information to a real environment. For example, an electronic bulletin board or an electronic memo may be used as the above-described virtual object. In this case, the action to the virtual object may be enlargement / reduction, editing, deletion, new creation, change of character color, etc., and the result information of the action is an enlarged or reduced image, editing It may be a later text or the like.
