JP7828001B2 - Game program, game system and game control method - Google Patents

Description

The present invention relates to a game program, a game system, and a game control method.

Some computer games that use the location information of a user's device restrict game processing if the user's device is determined to be moving too fast, in order to prevent the user from viewing the game screen while driving a bicycle or car. However, it is inconvenient for users if game processing is restricted even when using a means of transportation that the user does not drive themselves, such as a train or boat.

Patent Document 1 discloses a game in which the user selects the means of transportation to be used by touch operation, and then transitions to a mode corresponding to the selected means of transportation. When a car is selected as the means of transportation, a determination is made as to whether the user's device is stationary (whether the user is not moving), and if it is not stationary, the transition to drive mode is not made, and processing is performed to prompt the user to stop and perform another operation. On the other hand, when a mode corresponding to a means of transportation that the user does not drive is selected, it is possible to transition to the selected mode even while the user is moving.

JP 2021-153903 A

In games such as those described in Patent Document 1, which perform different processing depending on whether the user is using a means of transportation driven by the user or a means of transportation not driven by the user, it is desirable to be able to accurately determine whether the user is using a means of transportation driven by the user or a means of transportation not driven by the user.

The present invention therefore aims to provide a game program, game system, and game control method that can accurately determine the means of transportation used by a user in a computer game that uses location information from the user's terminal.

To solve the above problem, one aspect of the present invention provides a game program that causes a computer to function as: location information acquisition means for acquiring location information of a user terminal carried by a user; speed calculation means for calculating the movement speed of the user terminal based on the location information; speed determination means for determining whether the movement speed is equal to or greater than a predetermined speed limit; restriction means for restricting predetermined game processing that can be executed when the movement speed is determined to be equal to or greater than the speed limit, or when the movement speed is determined to be less than the speed limit; usage record acquisition means for acquiring usage record information regarding the use of public transportation; usage determination means for determining whether the user is currently using public transportation based on the usage record information; and invalidation means for invalidating the restriction on the game processing imposed by the restriction means when it is determined that the user is currently using public transportation.

This game program disables the restriction on game processing imposed by the restriction means when it is determined that the user is using public transportation, allowing the user to play the game without any restrictions on game processing even if the user's terminal travel speed exceeds the speed limit while using public transportation. Furthermore, because it determines whether the user is using public transportation based on usage record information related to the use of public transportation, it is possible to accurately determine the means of transportation the user is using.

After disabling the restriction on the game processing, the disabling means may determine whether a predetermined disabling condition is met, and if it is determined that the disabling condition is met, may release the disabling of the restriction on the game processing.

The invalidation cancellation condition may include a condition that the location of the user terminal indicated by the location information is not on the route of the public transportation facility.

The invalidation release condition may include a condition that the elapsed time from a predetermined point in time after the restriction on the game processing was disabled exceeds a predetermined invalidation release time.

After disabling the restriction on the game processing, the disabling means may determine whether a predetermined recording request condition is met, and if it is determined that the recording request condition is met, may display on the user terminal an image requesting the user to perform an operation to obtain the usage record information.

The recording request condition may include a condition that the location of the user terminal indicated by the location information is not on the route of the public transportation facility.

The recording request condition may include a condition that the elapsed time from a predetermined point in time after the acquisition of the usage record information exceeds a predetermined recording request time.

The recording request condition may include a condition that the location of the user terminal indicated by the location information has reached a predetermined stop on the route of the public transportation system.

The disabling means may cause the user terminal to display an image indicating that the game processing restriction has been disabled while the game processing restriction is being disabled.

The usage record acquisition means may acquire the usage record information by performing image recognition processing on an image of proof indicating that the public transportation system is being used.

A game system according to one aspect of the present invention includes a program storage unit that stores the game program, and a computer that executes the program stored in the program storage unit.

A game control method according to one aspect of the present invention is a game control method for controlling a game that progresses in response to user operations on a user terminal, and includes: a location information acquisition step for acquiring location information of the user terminal; a speed calculation step for calculating the movement speed of the user terminal based on the location information; a speed determination step for determining whether the movement speed is equal to or greater than a predetermined speed limit; a restriction step for restricting executable predetermined game processing if it is determined that the movement speed is equal to or greater than the speed limit, or if it is determined that the movement speed is less than the speed limit; a usage record acquisition step for acquiring usage record information regarding the use of public transportation; a usage determination step for determining whether the user is using the public transportation based on the usage record information; and an invalidation step for invalidating the restriction on the game processing if it is determined that the user is using the public transportation.

According to one aspect of the present invention, in a computer game that uses location information from a user's device, it is possible to accurately determine the means of transportation used by the user.

The following describes a game system 1 according to one embodiment of the present invention, with reference to the drawings.

First Embodiment
[Hardware configuration]
1 is a block diagram showing the hardware configuration of a game system to which a game program according to an embodiment of the present invention is applied. As shown in FIG. 1, the game system 1 includes a plurality of user terminals 2 and a server 3 that can communicate with each of the plurality of user terminals 2 via a communication network NW.

The user terminal 2 is a game device operated by a user. At least a portion of a game program is installed on the user terminal 2, and the game is executed on the user terminal 2. The user terminal 2 moves with the user who owns the user terminal 2. For example, the user terminal 2 is a portable computer device such as a smartphone operated by the user.

The user terminal 2 is equipped with a processor such as a CPU 10 that controls its operation, and this CPU 10 is connected to an operation input unit 12, a storage device 14, a ROM 15, and a RAM 16 via a bus 11. The storage device 14, ROM 15, and RAM 16 may collectively be referred to as the memory of the user terminal 2. Note that Figure 1 illustrates the configuration of one of multiple user terminals 2, and does not illustrate the other user terminals 2, but the configuration of the other user terminals 2 is similar to the configuration of the one user terminal 2.

The user terminal 2 is configured so that the user holds a mobile housing equipped with a monitor 19, which serves as a display unit. The mobile housing is equipped with an operation input unit 12. In this embodiment, each component of the user terminal 2 is housed within the mobile housing.

ROM 15 is a semiconductor memory such as mask ROM or PROM, and stores programs such as a startup program for starting up the user terminal 2. RAM 16 is composed of DRAM or SRAM, and reads and temporarily stores the game program 30a to be executed by the CPU 10 and various game data 30b required for that execution, depending on the game execution status.

Furthermore, the CPU 10 is connected via the bus 11 to a graphics processing unit 17, an audio synthesis unit 20, a network interface 25, an imaging unit 26, a location information receiving unit 27, and a near field communication (NFC) interface 28.

Of these, the graphics processing unit 17 draws predetermined application images, including a user image display unit that displays user images, in accordance with instructions from the CPU 10. The graphics processing unit 17 is also connected to a monitor 19 built into the user terminal 2 via a video conversion unit 18, and the application images drawn by the graphics processing unit 17 are converted into video format by the video conversion unit 18 and displayed on the monitor 19.

The audio synthesis unit 20 plays and synthesizes digital game sounds in accordance with instructions from the CPU 10. An external speaker 22 is also connected to the audio synthesis unit 20 via an audio conversion unit 21. Therefore, the game sounds played and synthesized by the audio synthesis unit 20 are decoded into analog format by the audio conversion unit 21 and output externally from the speaker 22.

The network interface 25 is communicatively connected to the server 3 via a communication network NW such as the Internet.

The imaging unit 26 is provided on the side opposite and/or on the display surface side of the monitor 19 of the mobile housing, and captures images of the external scenery. The captured image data is stored in the storage device 14.

The location information receiving unit 27 receives information about the current location of the user terminal 2. The location information receiving unit 27 is composed of, for example, a GPS satellite receiver.

The short-range wireless communication interface 28 communicates with an IC card or the like equipped with a short-range wireless communication chip. For example, the IC card may be a transportation IC card used to settle service fees for specific public transportation services. For example, a transportation IC card may have the function of automatically settling public transportation fares using pre-loaded funds. Furthermore, for example, a transportation IC card may function as a commuter pass for free use within a predetermined period and area. The transportation IC card may record the balance, date of use, time of use, and the like. For example, if the transportation IC card is a card used to pass through a ticket gate at a train station, when the transportation IC card is swiped over the automatic ticket gate installed at the ticket gate, an entry record or exit record is recorded on the transportation IC card. An entry record may also be referred to as a boarding record. An exit record may also be referred to as a disembarking record.

The operation input unit 12 consists of a touch panel provided on the monitor 19, and when the user touches an operation button or the like displayed on the monitor 19, the corresponding operation input is performed.

On the other hand, server 3 is equipped with a high-performance CPU 40 that controls its operation, and this CPU 40 is connected to a storage device 42, ROM 43, RAM 44, and network interface 45 via a bus 41.

The ROM 43 of the server 3 is a semiconductor memory such as a mask ROM or PROM, and stores basic programs for realizing the basic operation of the server 3, such as programs that control communication between the server 3 and other user terminals 2.

The RAM 44 is composed of DRAM, SRAM, etc., and temporarily stores programs to be executed by the CPU 40 and data required for execution, read from the storage device 42, etc.

The network interface 45 is communicatively connected to each user terminal 2 via a communication network NW such as the Internet.

In this embodiment, the game system 1 operates using so-called native applications.

The storage device 42 of the server 3 is a large-capacity storage medium built into the server 3. The storage device 42 of the server 3 stores a game program 42a to be executed by the CPU 40 of the server 3 and various game data 42b used therein. The CPU 40 saves and manages information sent from each user terminal 2 (account). The server 3 and user terminal 2 communicate with each other via the communication network NW.

To execute the app based on user operations, the user terminal 2 receives (downloads and installs) at least a portion of the game program 42a and at least a portion of the game data 42b stored in the storage device 42 of the server 3 via the communication network NW. Furthermore, the user terminal 2 receives (downloads and installs) the game program and game data for updates from the server 3.

The user terminal 2 progresses through the app on the user terminal 2 based on the installed game program and game data, and outputs effects (images, sounds) accompanying the progress of the app to the monitor 19, speaker 22, etc.

Each of the multiple user terminals 2 is assigned different account information (unique identification information) for each user operating that user terminal 2. An ID (identification code) is then assigned to each piece of account information. When each user terminal 2 transmits (uploads) specified information along with its ID to the server 3, the CPU 40 of the server 3 stores that information in the storage device 42 along with the corresponding ID.

[Game Overview]
In the game of this embodiment, the user controls a player character placed in a virtual space to fight non-player characters (monsters) that appear in the virtual space and obtain in-game objects such as items placed in the virtual space.

[Functional configuration]
2 is a block diagram showing the functional configuration of the game system 1 according to the present embodiment. As shown in FIG. 2, the user terminal 2 operates as a computer equipped with a control unit 5a including a CPU 10, a storage device 14, a ROM 15, a RAM 16, a graphics processing unit 17, an audio synthesis unit 20, etc. The server 3 operates as a computer equipped with a control unit 5b including a CPU 40, a storage device 42, a ROM 43, a RAM 44, etc.

As shown in FIG. 2, the control unit 5 of the game system 1, which is configured by the control unit 5a of the user terminal 2 and the control unit 5b of the server 3 working together, executes the game programs 30a and 42a to perform functions such as a position information acquisition means 51, a game execution means 52, a speed calculation means 53, a speed determination means 54, a restriction means 55, a usage record acquisition means 56, a usage determination means 57, and an invalidation means 58.

The location information acquisition means 51 acquires location information of the user terminal 2. The location information indicates the current location of the user terminal 2 in real space.

The game execution means 52 executes a predetermined game. The game execution means 52 executes a game according to the position of the user terminal 2 in real space.

Figure 3 shows an example of a game screen G1 in this embodiment. The game execution means 52 forms a virtual space S that corresponds to real space and displays the virtual space S on the monitor 19.

Specifically, as shown in FIG. 3, the game execution means 52 acquires map data of the virtual space S that corresponds to the map of real space, and displays the map of the virtual space S on the monitor 19. The game execution means 52 may generate the map data of the virtual space that corresponds to the map of real space by processing real-world map data on the user terminal 2, or may download it from the server 3. As shown in FIG. 3, the virtual space S includes virtual roads, railroads, rivers, seas, etc. that respectively correspond to roads, railroads, rivers, seas, etc. in real space. The virtual space S may also include virtual buildings that correspond to buildings in real space.

The game execution means 52 places the player character at a position in the virtual space S that corresponds to the position of the user terminal 2 in real space (i.e., the user's current position). A mark C1 indicating the position of the player character is shown on the map of the virtual space S on the game screen G1. As the user who owns the user terminal 2 moves in real space, the player character in the virtual space S also moves. In other words, as the coordinates of the user terminal 2 change in real space, the coordinates of the self-position mark C1 on the map of the virtual space S also change. Because the self-position mark C1 is fixed near the center of the game screen G1, the area of the virtual space S displayed on the game screen G1 changes as the user moves.

The game execution means 52 causes an enemy character or an item to appear at a predetermined position or a randomly selected position in the virtual space S. On the map of the virtual space S in the game screen G1, an enemy position mark C2 indicating the position of the enemy character and an item position mark B indicating the position of the item are displayed.

When the distance between the player's position mark C1 and the enemy position mark C2 on the map of the virtual space S, i.e., the distance between the player character and the enemy character, is less than a predetermined value, the player character can fight the enemy character by operating the user terminal 2. For example, when the user touches an enemy character on the screen that is within a predetermined range of the player character, a battle begins between the player character and the enemy character that was touched.

If the distance between the self-position mark C1 and the item position mark B on the map of virtual space S, i.e., the distance between the player character and the item in virtual space S, is less than a predetermined value, the player character can acquire the item by operating the user terminal 2. For example, if the user touches an item on the screen within a predetermined range of the player character, the player character acquires the item that was touched.

In this specification, when a user or a character corresponding to a user owns or acquires various game elements such as items, it means that the game elements are associated with the user, and more specifically, that the game elements are stored and directly or indirectly linked to the user's identification information. In this embodiment, the game elements are stored and linked to the user's identification information in both the memory on the user terminal 2 and the memory on the server 3, but they may also be stored in only one of the memory on the user terminal 2 or the memory on the server 3.

In this embodiment, the game mode switches between normal mode, restricted mode, and restricted disabled mode. The game screen G1 shown in FIG. 3 is the screen displayed when the game mode is normal mode. When the game mode is restricted mode or restricted disabled mode, a game screen different from the game screen G1 in normal mode is displayed on the monitor 19. Details of each game screen in restricted mode and restricted disabled mode will be described later.

Returning to Figure 2, the speed calculation means 53 calculates the movement speed of the user terminal 2 based on the location information acquired by the location information acquisition means 51.

The speed determination means 54 determines whether the travel speed calculated by the speed calculation means 53 is equal to or greater than a predetermined speed limit. The speed limit is set to determine whether the user terminal 2 is traveling by some kind of vehicle. For example, the speed limit is set to 10 km/h or greater. In other words, in this game, if the travel speed calculated by the speed calculation means 53 is equal to or greater than the predetermined speed limit, the user is treated as being on some kind of vehicle.

The restriction means 55 sets the current game mode to restricted mode. Restricted mode is a mode intended to prevent the user from playing the game while driving, for example, a bicycle or car. Specifically, the restriction means 55 restricts predetermined game processes that can be executed when the speed determination means 54 determines that the moving speed is equal to or greater than the speed limit, or when the moving speed is determined to be less than the speed limit. In other words, when the speed determination means 54 determines that the moving speed is equal to or greater than the speed limit, the restriction means 55 sets the game mode to restricted mode, which restricts predetermined game processes that can be executed in normal mode. In other words, restricted mode is a mode in which game processes that could be executed in normal mode are rendered unexecutable.

While the user is driving the vehicle, the vehicle may frequently stop, for example, at traffic lights. For this reason, to prevent the game mode from transitioning from restricted mode to normal mode while the user is driving the vehicle, restricted mode may be maintained for a certain period of time even after the movement speed of the user terminal 2 has decreased from a speed above the speed limit to a speed below the speed limit.

The usage record acquisition means 56 acquires usage record information regarding the use of public transportation. The usage record information is information that records that the user is using public transportation. In other words, the usage record information is information that proves that the user is using public transportation. Examples of public transportation include trains and other rail vehicles, trams, buses, taxis, airplanes, and ships.

The method by which the usage record acquisition means 56 acquires usage record information is not particularly limited. For example, the method of acquiring usage record information may differ depending on the type of public transportation. The usage record acquisition means 56 may acquire usage record information using, for example, a transportation IC card, specific application software installed on the user terminal 2, or a paper ticket.

Acquisition from an IC card For example, when a user passes their transportation IC card over an automatic ticket gate to board a train and enter the station platform through the ticket gate, an entry record is recorded on the transportation IC card. Then, when the user passes the transportation IC card over the user terminal 2, the user terminal 2 reads the entry record recorded on the transportation IC card via the short-range wireless communication interface 28. In the user terminal 2, the usage record acquisition means 56 acquires the read entry record as usage record information.

Acquisition from Application Software For example, if application software (hereinafter referred to as a transportation app) equipped with the functionality of a transportation IC card is installed on the user terminal 2, the user can enter the station platform through the ticket gate by holding the user terminal 2 over an automatic ticket gate. When the user terminal 2 is held over the automatic ticket gate, an entry record is recorded in the memory of the user terminal 2. The usage record acquisition means 56 acquires the entry record saved in the transportation app as usage record information. In this case, the transportation app and the game app (game program) may need to be linked to enable the entry record data saved in the transportation app to be commonly used as usage record information in the game. Furthermore, acquisition of usage record information from the transportation app may be performed by a user's operation of the user terminal 2, or may be automatically performed periodically or irregularly during gameplay.

Acquisition from a Paper Ticket For example, when a user rides a train using a paper ticket (which may also be referred to as a paper usage ticket), the usage record acquisition means 56 can acquire usage record information by performing image recognition processing on a captured image of the paper ticket, which serves as proof that the user is using public transportation. Specifically, the user captures an image of the paper ticket using the imaging unit 26 of the user terminal 2, and the captured image of the paper ticket is saved in memory. The usage record acquisition means 56 performs image recognition processing on the captured image to determine whether the captured image includes an image of a paper ticket for public transportation, and if the captured image includes an image of a paper ticket for public transportation, the captured image or information included in the captured image (e.g., text information) is used as usage record information.

For example, if a one-dimensional or two-dimensional code containing usage record information is printed on a paper ticket, the usage record acquisition means 56 can acquire the usage record information by reading this code with the user terminal 2. Paper tickets are not limited to tickets, but can also be tickets for different types of public transportation, such as airline tickets.

The usage determination means 57 determines whether the user is using public transportation based on the usage record information acquired by the usage record acquisition means 56.

The usage determination means 57 can determine whether the user is using public transportation based on whether the usage record information satisfies predetermined usage determination conditions. The usage determination conditions are not particularly limited.

For example, the usage determination condition may include a condition that the usage record information includes an entry record, but does not include an exit record corresponding to the most recent entry record. That is, for example, when the usage record means 56 acquires usage record information from a transportation IC card or transportation app, the usage determination means 57 may determine that the user is using public transportation if the usage record information includes an entry record, but does not include an exit record corresponding to the most recent entry record. This is because, since the usage record information does not include an exit record corresponding to the most recent entry record, it is presumed that the user has not left a public transportation platform (e.g., a station ticket gate) since entering that platform.

For example, the usage determination condition may include a condition that the date of use indicated in the usage record information matches the current day determined by the usage determination means 57. That is, for example, the usage determination means 57 may determine that the user is using public transportation if the date of use indicated in the usage record information matches the current day determined by the usage determination means 57, and may determine that the user is not using public transportation if the date of use indicated in the usage record information does not match the current day determined by the usage determination means 57. By setting such a usage determination condition, it is possible to prevent the user from being determined to be using public transportation based on past entry records recorded on a transportation IC card or transportation app, used tickets, etc.

The usage determination condition may be changed depending on the method of acquiring usage record information and the type of public transportation. For example, when acquiring usage record information from a transportation IC card or transportation app, the usage determination condition may be set to a condition that the usage record information includes an entry record, but does not include an exit record corresponding to the most recent entry record. When acquiring usage record information by capturing an image of a paper ticket, a different usage determination condition may be set, for example, a condition that the date of use indicated in the usage record information matches the current date determined by the usage determination means 57.

In this embodiment, in addition to the above-mentioned determination using the usage record information (hereinafter referred to as the "first usage determination"), the usage determination means 57 also makes a determination without using the usage record information (hereinafter referred to as the "second usage determination"), and determines whether the user is using public transportation based on the results of these determinations. That is, if the usage determination means 57 determines that the user is using public transportation in the first usage determination, it further makes a second usage determination, and if the second usage determination also determines that the user is using public transportation, it makes a final determination that the user is using public transportation.

In other words, if the usage determination means 57 determines that the user is using public transportation in both the first usage determination and the second usage determination, it makes a final determination that the user is using public transportation; and if it determines that the user is not using public transportation in at least one of the first usage determination and the second usage determination, it makes a final determination that the user is not using public transportation.

The second usage determination is a determination using the location information acquired by the location information acquisition means 51. The usage determination means 57 determines whether the location of the user terminal 2 indicated by the location information acquired by the location information acquisition means 51 is on the public transportation route indicated by the usage record information. For example, if the usage determination means 57 makes a first usage determination based on train usage record information, the usage determination means 57 makes a second usage determination of whether the location of the user terminal 2 is on the train tracks. If the location of the user terminal 2 is on the public transportation route, it determines that the user is using public transportation.

The disabling means 58 sets the current game mode to the restriction-disabled mode. Specifically, the disabling means 58 disables the restriction on game processing imposed by the restriction means 55 when the usage determination means 57 determines that the user is using public transportation. In other words, even if the moving speed of the user terminal 2 is equal to or greater than the speed limit, the disabling means 58 does not restrict the game processing that is subject to restriction by the restriction means 55 when it is determined that the user is using public transportation.

[Game Processing]
Next, the game processing in this embodiment will be described in detail. Fig. 4 is a flowchart showing an example of the flow of the game processing in this embodiment, particularly the processing related to switching of the game mode. By the game processing in this embodiment, the game mode is switched between normal mode, restricted mode, and restricted disabled mode.

As shown in Figure 4, in the game processing, the location information acquisition means 51 acquires location information of the user terminal 2 (step S1).

The game execution means 52 determines whether the current game mode is the restriction-disabled mode (step S2). If it is determined that the current game mode is the restriction-disabled mode (step S2: Yes), restriction-disabled processing is executed. The restriction-disabled processing will be described in detail below.

If it is determined that the current game mode is not the restriction-disabled mode (step S2: No), the usage determination means 57 determines whether usage record information regarding the use of public transportation has been acquired by the usage record acquisition means 56 (step S3).

If the usage record acquisition means 56 determines that usage record information regarding the use of public transportation has been acquired (step S3: Yes), the usage determination means 57 determines whether the user is currently using public transportation (step S4).

If it is determined in step S3 that usage record information has not been acquired (step S3: No), or if it is determined in step S4 that the user is not using public transportation (step S4: No), the speed calculation means 53 calculates the movement speed of the user terminal 2 based on the location information acquired by the location information acquisition means 51 (step S5).

The speed determination means 54 determines whether the movement speed calculated by the speed calculation means 53 is equal to or greater than a predetermined speed limit (step S6).

If the speed determination means 54 determines that the movement speed is equal to or greater than the speed limit (step S6: No), the game execution means 52 changes the current game mode to normal mode (step S7).

When the game mode is normal mode, as described above, the game execution means 52 controls the monitor 19 to display a game screen G1 corresponding to the position of the user terminal 2 in real space. That is, as shown in FIG. 3, the game execution means 52 forms a virtual space S that corresponds to the real space and displays the virtual space S. The game execution means 52 places the player character at a position in the virtual space S that corresponds to the position of the user terminal 2 in real space, and makes enemy characters or items appear at predetermined or randomly selected positions in the virtual space S. The player character moves within the virtual space in accordance with the user's movement in real space, and as a result of this movement, the player character may fight an enemy character or obtain an item.

If the speed determination means 54 determines that the movement speed is equal to or greater than the speed limit (step S6: Yes), the restriction means 55 sets the current game mode to the restricted mode (step S8). That is, the restriction means 55 restricts certain game processes that can be executed when the movement speed of the user terminal 2 is determined to be less than the speed limit. In this embodiment, if the speed determination means 54 determines that the movement speed is equal to or greater than the speed limit, the restriction means 55 restricts the game from progressing.

Figure 5 is a diagram showing an example of a game screen G2 in restricted mode. The game screen G2 is displayed on the monitor 19 when the speed determination means 54 determines that the movement speed is equal to or greater than the speed limit. The game screen G2 includes a warning message area M1. The warning message area M1 displays an image to notify the user that they are unable to continue playing the game because the movement speed of the user terminal 2 is equal to or greater than the speed limit. In the example of Figure 5, the warning message area M1 displays a text message stating "Play is being restricted because the movement speed is too fast," but the displayed content is not particularly limited.

In this embodiment, while the game mode is in restricted mode, the restriction means 55 disables all battles between the player character and enemy characters, and the player character's acquisition of items placed in the virtual space. Note that while the game mode is in restricted mode, only a portion of all game processing that was executable in normal mode may be restricted, or all game processing that was executable in normal mode may be restricted.

As shown in FIG. 5, the game screen G2 in restricted mode includes a restriction release button M2. When the user touches the restriction release button M2, an image is displayed on the monitor 19 prompting the user, who is using public transportation, to perform an operation to acquire usage record information. By following the guidance of this display and operating the user terminal 2 to acquire usage record information, the game mode can be switched from restricted mode to restriction disabled mode.

Returning to FIG. 4, if it is determined in step S4 that the user is using public transportation (step S4: Yes), the disabling means 58 sets the current game mode to the restriction-disabled mode (step S9). In other words, the disabling means 58 disables the restriction on game processing imposed by the restriction means 55. While the game mode is in the restriction-disabled mode, the restriction-disabled process is executed.

By repeating the above game processing, the game mode switches between normal mode, restricted mode, and restricted disabled mode.

[Restriction Disable Process]
The restriction invalidation process will be described with reference to Figures 6 and 7. Figure 6 is a flowchart showing the flow of the restriction invalidation process. The restriction invalidation process is executed when it is determined in step S2 of Figure 4 that the current game mode is the restriction invalidation mode. In other words, the restriction invalidation process is executed after the restrictions on the game processing are invalidated in step S9.

As shown in FIG. 6, in the restriction invalidation process, the invalidation means 58 displays a restriction invalidation image on the monitor 19 of the user terminal 2 (step S11).

Figure 7 shows an example of a game screen G3 in restriction-invalid mode. The game screen G3 is almost identical to the game screen G1 displayed in normal mode, except that it includes a restriction-invalid image M3. In other words, during restriction-invalid mode, the user can play the game in the same way as in normal mode.

Unlike the game screen G1 displayed in normal mode, the game screen G3 includes a restriction invalid image M3. The restriction invalid image M3 is an image indicating that restrictions on game processing have been disabled, in other words, that the game is being played in restriction invalid mode. In other words, the user can see that the current game mode is restriction invalid mode by looking at the restriction invalid image M3. In Figure 7, the restriction invalid image M3 is shown as an illustrated image of a train, which is a type of public transportation, but the display format of the restriction invalid image M3 is not particularly limited. The restriction invalid image M3 may also be an image corresponding to the type of public transportation being used. The restriction invalid image M3 may also be a text message indicating that the game is being played in restriction invalid mode.

Returning to FIG. 6, the invalidation means 58 determines whether or not a predetermined recording request condition has been met (step S12). If the invalidation means 58 determines that the recording request condition has been met (step S12: Yes), it displays an image requesting the user to perform an operation to obtain usage record information (hereinafter referred to as a "usage record request") on the monitor 19 of the user terminal 2 (step S13).

The recording request conditions may include at least one of the following (a1), (a2), and (a3).
(a1) The condition that the elapsed time from a predetermined point in time after the usage record acquisition means 56 acquires the usage record information exceeds a predetermined record request time.
(a2) The condition that the location of the user terminal 2 indicated by the location information acquired by the location information acquisition means 51 is not on a route of public transportation.
(a3) A condition that the position of the user terminal 2 indicated by the position information acquired by the position information acquisition means 51 has reached a predetermined stop point on the route of the public transportation.

For example, if the recording request conditions include multiple conditions, the invalidation means 58 may display a usage recording request when it is determined that all of the multiple conditions included in the recording request conditions are met, or may display a usage recording request when it is determined that any of the multiple conditions included in the recording request conditions are met.

The usage record request displayed in step S13 may prompt the user to perform an operation to obtain usage record information. For example, the invalidation means 58 may display a text message as the usage record request, such as "Please reload your usage history from the transportation app." For example, the invalidation means 58 may display a text message as the usage record request, such as "Please hold your transportation IC card over your smartphone." For example, the invalidation means 58 may display a text message as the usage record request, such as "Please take a photo of your paper ticket."

The invalidation means 58 also determines whether a predetermined invalidation release condition has been met (step S14). If the invalidation means 58 determines that the invalidation release condition has been met (step S14: Yes), it releases the invalidation of the restrictions on the game processing (step S15). That is, the invalidation means 58 changes the current game mode from the restricted invalidation mode to the normal mode or the restricted mode.

The invalidation cancellation condition may include at least one of the following (b1), (b2), and (b3).
(b1) The condition that the time elapsed from a predetermined point in time after the time when the restriction on game processing was disabled exceeds the predetermined time for disabling the restriction.
(b2) The condition that the location of the user terminal 2 indicated by the location information acquired by the location information acquisition means 51 is not on a route of public transportation.
(b3) A condition that the position of the user terminal 2 indicated by the position information acquired by the position information acquisition means 51 has reached a predetermined stop point on the route of the public transportation.

For example, if the invalidation release condition includes multiple conditions, the invalidation means 58 may release the invalidation of the restriction on the game processing when it is determined that all of the multiple conditions included in the invalidation release condition are satisfied, or may release the invalidation of the restriction on the game processing when it is determined that any of the multiple conditions included in the invalidation release condition are satisfied.

[summary]
To summarize the above, the game program of this embodiment causes the control unit 5 (computer) to function as: location information acquisition means 51 that acquires location information of the user terminal 2 carried by the user; speed calculation means 53 that calculates the movement speed of the user terminal 2 based on the location information; speed determination means 54 that determines whether the movement speed is equal to or greater than a predetermined speed limit; restriction means 55 that restricts predetermined game processing that can be executed when it is determined that the movement speed is equal to or greater than the speed limit, or when it is determined that the movement speed is less than the speed limit; usage record acquisition means 56 that acquires usage record information regarding the use of public transportation; usage determination means 57 that determines whether the user is using public transportation based on the usage record information; and invalidation means 58 that invalidates the restriction on the game processing by the restriction means 55 when it is determined that the user is using public transportation.

[Action and effect]
According to the game program of this embodiment, if it is determined that the user is using public transportation, the restriction on game processing by the restriction means 55 is disabled, so that the user can play the game without any restriction on game processing even if the movement speed of the user terminal 2 exceeds the speed limit while using public transportation. Furthermore, because it is determined whether the user is using public transportation based on the usage record information regarding the use of public transportation, it is possible to accurately determine the means of transportation used by the user. In other words, it is possible to accurately determine whether the reason the movement speed of the user terminal 2 exceeds the speed limit is due to the user's use of public transportation.

<Other embodiments>
The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention.

For example, in the above embodiment, an example of a game that uses the position information of the user terminal 2 (a game that corresponds to the computer's position) was given in which the virtual space S, which is the game space, is formed corresponding to the real space, and the player character is placed at a virtual space position that corresponds to the position of the user terminal 2. However, a game that uses the position information of the user terminal 2 may also be a game that does not have a virtual space that corresponds to the real space. For example, it may be a game in which a predetermined event occurs when the user terminal 2 is positioned at a predetermined position.

Furthermore, in a game executed by the user terminal 2, the position information of the user terminal 2 may be used only to calculate the movement speed of the user terminal. In other words, the present invention is applicable to any game that imposes restrictions on gameplay depending on the movement speed calculated based on the position information of the user terminal 2.

Furthermore, the user terminal may be any computer that can be used by a user while using public transportation. In the above embodiment, the user terminal 2 was described assuming a portable information terminal with a touch panel as the operation input unit 12, such as a smartphone or tablet PC, but the user terminal does not have to have a touch panel. For example, the present invention can also be applied to portable gaming devices with physical controls such as levers and buttons, and wearable devices such as smart watches, as long as the user terminal is configured to be operable by the user while using public transportation.

The user terminal 2 may also be equipped with a disk drive, memory card slot, HDD, or the like. In a user terminal equipped with a disk drive, the user terminal 2 may acquire application programs and application data by loading a disk-type storage medium such as a DVD-ROM into the disk drive. In a user terminal 2 equipped with a memory card slot, the user terminal 2 may be able to store save data on a card-type storage medium by loading the card-type storage medium.

Furthermore, in the above embodiment, the game system 1 includes a user terminal 2 and a server 3, but the game system of the present invention may be configured without a server.

The game program of the present invention may be executed by at least one computer, such as the user terminal 2 or the server 3. For example, a portion of the game program of the present invention may be stored on the server, and the remainder of the game program of the present invention may be downloaded to the user terminal or recorded on a recording medium for loading into the user terminal. For example, the control unit of the server may execute the game program stored in the storage device 42 to function as some or all of the functional units 51 to 58 described in the above embodiment. In this case, the game program of the present invention is a program stored on the server, or a program stored in a distributed manner on the user terminal 2 and the server 3.

Two steps shown in sequence in the flowchart described in the above embodiment may, in some cases, be performed simultaneously or in reverse order.

For example, in the game processing of FIG. 4, steps S5 and S6 may be executed before steps S2 and S3. That is, after step S1, the speed calculation means 53 may calculate the moving speed of the user terminal 2, and then step S2 may be executed if the speed determination means 54 determines that the moving speed is equal to or greater than the speed limit. If the game execution means 52 determines in step S2 that the current game mode is the restriction-disabled mode, a restriction-disabled process is executed. If the game execution means 52 determines that the current game mode is not the restriction-disabled mode, the usage determination means 57 may determine whether usage record information has been acquired. If it is determined that usage record information has been acquired and that the user is using public transportation, the disabling means 58 may set the current game mode to the restriction-disabled mode. If it is determined that usage record information has not been acquired or that the user is not using public transportation, the restriction means 55 may set the current game mode to the restriction-disabled mode.

Some steps in the flowcharts shown in Figures 4 and 6 may be omitted. For example, in the flowchart shown in Figure 4, step S4 may be omitted. For example, in the flowchart shown in Figure 6, steps S12 and S13 may be omitted.

Transportation IC cards only need to be able to be used for public transportation, and may also be used for other purposes such as shopping.

In the above embodiment, the usage determination means 57 made a final determination of whether or not the user is using public transportation based on the results of the first usage determination and the second usage determination. However, the usage determination means 57 does not need to make the second usage determination. In other words, the usage determination means 57 may use the result of the first usage determination as the final determination of whether or not the user is using public transportation.

In the above embodiment, the second usage determination was exemplified as a determination of whether the location of the user terminal 2 is on the public transportation route indicated by the usage record information, but the second usage determination is not limited to this. The second usage determination may be any determination using the location information acquired by the location information acquisition means 51.

For example, the second usage determination may be a determination that the user terminal 2 is traveling along a public transportation route and that there is no roadway running parallel to the route near the route along which the user terminal 2 is traveling. In real space, railroad tracks and roadways may be located one above the other and extend in the same direction; in such cases, the railroad tracks and roadway overlap on the map. When the user is located in an area where such railroad tracks and roadway overlap, it is difficult to determine from the map whether the user is in a car or a train. However, by determining that there is no roadway running parallel to the route, it is possible to accurately determine that the user is not in a car traveling on a roadway.

If a roadway is present near the route along which the user terminal 2 is traveling, it may be determined that the user is using public transportation when it is determined that the trajectory of the user terminal 2's travel is not along a roadway.

If this second usage determination determines that the user is using public transportation, the restriction disabled mode may be maintained for a certain period of time from the time this determination is obtained, regardless of whether there is a roadway running parallel to the route near the route.

For example, the second usage determination may be a determination as to whether the movement of the user terminal 2 matches the movement specific to public transportation, based on the location information acquired by the location information acquisition means 51. For example, if the second usage determination determines that the user terminal 2 stops only at predetermined stops (e.g., stations) on the public transportation route and does not stop at any other stops on the route, the result of the second usage determination may be a determination that the user is using public transportation. Alternatively, for example, if the second usage determination determines that the user terminal 2 slows down and stops as it approaches a predetermined stop (e.g., a station) on the public transportation route, the result of the second usage determination may be a determination that the user is using public transportation.

In the above condition (a1), the predetermined point in time after the time the usage record information is acquired may be the time the usage record information is acquired, or the time when it is determined in step S4 that the user is using public transportation. The predetermined point in time may also be the time when the previous usage record request was made.

Furthermore, in the above condition (a1), the recording request time may be a fixed time set in advance, or may be a time that varies depending on the type of public transportation determined to be in use, the duration of use of the public transportation, etc.

In the above condition (b1), the predetermined point in time after the point in time when the restriction on game processing is disabled may be the point in time when usage record information is acquired, or the point in time when it is determined in step S4 that the user is using public transportation. The predetermined point in time may also be the point in time when the usage record request is displayed in step S13.

In the above conditions (a2) and (b2), the route of the public transportation may be a railroad track if the public transportation is a rail vehicle. The route of the public transportation may be a bus route if the public transportation is a bus. The route of the public transportation may be a sea route if the public transportation is a ship or airplane. Information on the map of the virtual space S that corresponds to the map of the real space may include route information that corresponds to the route of the public transportation in the real space.

In the above conditions (a3) and (b3), the predetermined stop point may be a train station if the public transportation is a railroad vehicle. The predetermined stop point may be a bus stop if the public transportation is a bus. The predetermined stop point may be a port if the public transportation is a ship. The predetermined stop point may be, for example, an airport on the way to a destination airport if the public transportation is an airplane. Information on the map of virtual space S corresponding to the map of real space may include information indicating virtual stop positions corresponding to the positions of public transportation stop points in real space.

For example, if the record request condition is (a3) that the position of the user terminal 2 indicated by the position information acquired by the position information acquisition means 51 has reached a predetermined stop on the public transportation route, and the disablement release condition is (b3) that the position of the user terminal 2 indicated by the position information acquired by the position information acquisition means 51 has reached a predetermined stop on the public transportation route, the restriction disabled mode can be continued until the public transportation arrives at the next stop. In this case, the user will not be required to acquire usage record information until the public transportation arrives at the next stop, allowing the user to play the game comfortably.

The recording request conditions are not limited to the above (a1), (a2), and (a3). The recording request conditions may include other conditions instead of or in addition to at least one of the above (a1), (a2), and (a3).

The invalidation release conditions are not limited to (b1), (b2), and (b3) above. The invalidation release conditions may include other conditions instead of or in addition to at least one of the conditions (b1), (b2), and (b3) above. For example, the invalidation release condition may include a condition that a certain period of time has passed since the movement speed of the user terminal 2 became equal to or less than the speed limit. This is because if a certain period of time has passed since the movement speed of the user terminal 2 became equal to or less than the speed limit, it is highly likely that the user has gotten off public transportation. In this case, if the invalidation release condition that a certain period of time has passed since the movement speed of the user terminal 2 became equal to or less than the speed limit is satisfied, the invalidation means 58 changes the current game mode from the limit-invalidated mode to the normal mode.

For example, a user may frequently use the same public transportation system to commute to work or school. It can be a hassle for the user to perform an operation to obtain usage record information every time they use public transportation. It may be possible to make it possible to omit the user operation to obtain usage record information under certain conditions. This can reduce the user's effort.

For example, once usage record information is acquired, it may be used only once to determine whether the user is using public transportation, or it may be able to be used multiple times, or it may be able to be used multiple times for a specified period of time. The usage record information does not have to be used for the usage determination immediately after it is acquired, but may be used after a period of time, such as several days after the date of acquisition of the usage record information. If the game mode was once able to be switched to restriction-disabled mode as a result of a determination based on the usage record information, it may be possible to omit the user's operation to acquire usage record information when switching to restriction-disabled mode thereafter under specified conditions.

For example, the usage record information may include route information regarding the route of public transportation used by the user. The route information may be, for example, information indicating a commuter pass section, or a predetermined area in which the target public transportation may be located. When usage record information regarding the use of public transportation is acquired by the usage record acquisition means, the usage record information is stored in memory of the user terminal. The usage determination means may determine whether the user is using public transportation based on the usage record information stored in memory. Specifically, the usage determination means may determine whether the user's position (more specifically, the position indicated by the position information acquired by the position information acquisition means) is on the route indicated by the route information included in the usage record information in the memory, and if it is determined that the user's position is on the route, determine that the user is using public transportation.

For example, the usage record information may include, in addition to route information, expiration information regarding the expiration date of the usage record. The expiration information may be, for example, information indicating the expiration date of a commuter pass, or information indicating a predetermined period (e.g., one month) from the time the usage record information was acquired. The usage determination means may be able to use only usage record information that has not yet expired, as indicated by the expiration information, from among the usage record information previously stored in the memory of the user terminal, to determine whether the user is currently using public transportation.

Usage record information regarding the use of public transportation acquired on a user terminal (hereinafter referred to as a first user terminal) may be used to disable restrictions on game processing on another user terminal (hereinafter referred to as a second user terminal). This may allow, for example, operations to acquire usage record information to be omitted for some users among multiple users traveling together on the same public transportation.

For example, suppose a first user carrying a first user terminal and a second user carrying a second user terminal are playing the same game on their respective user terminals, and the first user terminal determines that the user is using public transportation based on acquired usage record information, resulting in the game mode being set to restriction-disabled mode. In this case, the game mode of the second user's second user terminal may also be set to restriction-disabled mode if the relationship condition that the first user terminal and the second user terminal are in a predetermined relationship is met, even without the second user terminal acquiring usage record information.

The relationship condition may include a condition that the location of the second user terminal matches the location of the first user terminal or is located within a predetermined range from the first user terminal. In this case, the control unit 5a of the second user terminal may determine whether the location of the second user terminal matches the location of the first user terminal or is located within a predetermined range from the first user terminal based on the current location information of the second user terminal received by the location information receiving unit 27 of the second user terminal and the current location information of the first user terminal received from the first user terminal by the location information receiving unit 27 of the first user terminal.

In addition to the above conditions related to the relative positions of the user terminals, the relationship conditions may also include a condition that the first user and the second user have registered as friends within the game, establishing a predetermined friendly relationship. Friend registration is performed using known methods. For example, friend registration is performed when one of the first and second user terminals sends a friend request to the other of the first and second user terminals via a server, and the other of the first and second user terminals accepts the friend request upon receiving it.

The effects of the present invention will be achieved even when these other embodiments are adopted. Furthermore, this embodiment, its variations, and other embodiments can be combined as appropriate.
