  Hereinafter, a server, a terminal, and an information processing apparatus according to an embodiment of the present invention will be described. Note that the server, terminal, and information processing apparatus described below are for explaining the gist of the present invention, and the technical scope of the present invention is not limited to the embodiments described below. . In addition, the elements described in each embodiment can be omitted as appropriate according to the application. Thus, various servers, terminals, and information processing apparatuses configured according to the principles of the present invention, methods executed by each of these, programs executed by each of these, and equivalents thereof Any such invention is within the scope of the present invention.

(Hardware that implements servers and terminals)
The server and the terminal according to the present embodiment are typically realized by an information processing apparatus including a computer executing a program. Here, as a computer, a computer such as a server computer, a desktop computer, a notebook computer, a tablet computer, etc., which is manufactured and sold as a computer, a mobile phone, a smart phone, a tablet phone, etc. In addition, those manufactured and sold as telephones, and those manufactured and sold as game machines and multimedia terminals such as portable game machines and home entertainment devices are also included. Typically, the information processing apparatus according to the present embodiment is realized on a high-performance stationary computer, a cloud computer, or the like, and the terminal is realized on a smartphone, a portable game machine, or the like.

  Programs executed on computers and various types of data referenced by the programs can be distributed and sold by servers connected to the computer so that they can communicate with each other, and CD-ROM (Compact Disk Read Only Memory) , Recorded on non-transitory information recording media such as DVD-ROM (Digital Versatile Disk ROM), flash memory, EEPROM (Electrically Erasable Programmable ROM), then distributed, sold, etc. It is also possible to do.

  The program is installed in a non-transitory information recording medium such as a hard disk, a solid state drive, a flash memory, and an EEPROM included in the computer. Then, the information processing apparatus in the present embodiment is realized by the computer. Generally, a computer's CPU (Central Processing Unit) reads a program from an information recording medium to a RAM (Random Access Memory) under the management of the computer's OS (Operating System), and then the code included in the program Is interpreted and executed. However, a portable game machine or the like may employ an architecture that can map an information recording medium in a memory space accessible by the CPU. In this case, there is no need to install the program or explicitly load the program into the RAM.

  Various kinds of information required in the course of program execution can be temporarily recorded in a CPU register, RAM, or cache.

  The result of the processing in the information processing apparatus can be displayed on a display device such as a display or a touch screen using characters or images, and sound based on the result of the processing can be output to a speaker or headphones.

  In addition, the processing result can be recorded on an information recording medium and used later or referenced by other devices. Furthermore, processing results can be distributed and sold via a computer communication network or the like.

  A user can give various instructions to the information processing apparatus via a controller for a game device such as a keyboard, a mouse, a trackball, a touch pad, and a joystick, and an input device such as a touch screen.

  In addition, when the information processing apparatus includes an acceleration sensor or a posture sensor, the information processing apparatus has various operations such as swinging down, swinging up, or performing a shake operation that repeats these operations. It is also possible to use various instructions given to the apparatus.

  Furthermore, it is also possible to use various instructions given to the information processing apparatus by sound detected by a microphone included in the information processing apparatus.

  Note that the information processing apparatus according to the present embodiment can be configured by constructing a dedicated electronic circuit instead of realizing the information processing apparatus according to the present embodiment by executing a program on a general-purpose computer.

  Also in this aspect, it is possible to use a definition program obtained by describing in the same way as an execution program to be executed by a computer or by moving the execution program after making a relatively simple modification.

  Although the definition program appears to be an execution program at first glance, in practice, the electronic elements that realize the processing described in the definition program are wired instead of sequentially executing the processing described in the definition program. Or functions as a specification definition for determining a timing chart of operation in each element.

  In such an aspect, an electronic circuit that satisfies the specifications defined in the program is configured by an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit), and the electronic circuit has a function defined in the program. The information processing apparatus of this embodiment can be realized by functioning as a dedicated device that fulfills the above.

  In the following, in order to facilitate understanding, an aspect in which the information processing apparatus according to the present embodiment is realized by a computer executing a program will be described.

(Game system)
FIG. 1 is an explanatory diagram showing an example of the game system according to the embodiment of the present invention. Hereinafter, a description will be given with reference to FIG.

  In the game system 101 according to the present embodiment, one server 111 and a plurality of terminals 151 are communicably connected via the Internet 191.

  The server 111 according to the present embodiment is realized by executing a server program in a server computer that is a high-performance information processing apparatus.

  On the other hand, each terminal 151 is realized by executing a terminal program in a smart phone or a portable game machine that is a portable information processing apparatus. The terminal program is a part of the game application, which detects the position of the terminal 151 intermittently from the reception status of SSID beacons at the GPS and Wifi access points, for example, at intervals of several seconds, via the Internet 191. The server 111 is notified of the position.

  When the server 191 sends an instruction according to the progress of the game to the terminal 151 according to the position of each terminal 151, the game application operating on the terminal 151 performs screen display or audio output according to the instruction. The game progress is presented to the user.

  Thus, as one of the factors determined by the progress of the game, a game in which the position of each terminal 151 is used may be called a location game. In addition, a game that progresses using the positions of a plurality of terminals 151, that is, the positional relationship between a plurality of users may be referred to as a social location game. This embodiment can be applied to any location game in which some event occurs when users approach each other.

(server)
FIG. 2 is an explanatory diagram showing a schematic configuration of a server in the game system. Hereinafter, a description will be given with reference to FIG.

  As shown in the figure, the server 111 includes a collection unit 112, a calculation unit 113, an extraction unit 114, an estimation unit 115, a storage unit 116, a selection unit 117, and an instruction unit 118.

  Here, the collection unit 112 intermittently collects the positions of the terminals 151 of the plurality of terminals 151.

  As described above, the terminal 151 intermittently detects the SSID of the GPS or connectable Wifi access point, and transmits it to the server 111. The collection unit 112 of the server 111 receives this and accumulates information on which terminal 151 is located where.

  On the other hand, for each terminal 151, the calculation unit 113 moves the terminal 151 from the latest collected latest position and latest date and time, the previous position and previous date and time collected immediately before the latest position and latest date and time. Calculate the speed.

  If the latest position and the latest date and time collected from a certain terminal A among the plurality of terminals 151 and the previous position and the previous date and time collected just before that from the terminal A are known, the speed of the terminal A is “the latest It can be calculated by dividing the “distance between the position and the previous position” by the “difference between the latest date and the previous date”.

  Further, for the terminal 151 whose calculated speed is slow on a predetermined basis, the extraction unit 114 passes through a plurality of sections that divide the map from a plurality of sections that divide the map to a path from the immediately preceding position collected for the slow terminal 151 to the latest position To extract.

  Here, the map is a map showing the area where this game is provided, and the size of each partition is how close the users are to each other, and the location detection by GPS or Wifi Depending on how much the error is, it can be determined as appropriate. Typically, squares or rectangles along the earth's surface, such as several meters to several kilometers along meridians and latitudes, are employed.

  The extraction unit 114 extracts the passing section of the terminal A when the moving speed of the terminal A is sufficiently slow based on a predetermined reference. Here, “slow according to a predetermined standard” corresponds to a situation where a human walks, stops, or stays in the place while looking around. Since the movement speed by human walking is about 3 to 4 kilometers per hour, for example, if the movement speed is 1 kilometer or less per hour, it is possible to set a standard for a slow terminal. Further, the fact that the terminal A is sufficiently slow on the predetermined standard can also be considered as a high possibility that the user of the terminal A is staying at the place.

  The extraction unit 114 checks which section in the map has passed when the slow terminal A moves from the previous position to the latest position. Since the position information of the terminal A obtained by GPS or the like is expressed by latitude and longitude, the extraction of the passing section can be reduced to the intersection problem between the line segment and the square, and high-speed calculation is possible. When the speed of the terminal A is sufficiently slow and the latest date and time are close to the previous date and time, the previous position and the latest position are often the same section or adjacent sections.

  Then, the estimation unit 115 estimates the passage date and time when the late terminal 151 passes through the extracted passage section. Assuming that terminal A moves from the previous position to the latest position at a constant speed at the calculated speed, the passage date and time that passed through each passage section is the date and time when the entry to the passage section (the side of the rectangle intersects the route) And the average of the date and time when the passage section leaves (the other side of the square intersects the route). Moreover, the passage date and time of the passage section including only the immediately preceding position may be the immediately preceding date and time, and the passage date and time of the passage section including only the latest position may be the latest date and time. The passing date and time of the passing section including both the latest position and the immediately preceding position may be an average of the immediately preceding date and the latest date and time.

  On the other hand, the storage unit 116 associates the extracted passage section, the late terminal 151, and the estimated passage date and time and stores them for a predetermined period.

  That is, the storage unit 116 records the above information in a storage device such as a hard disk or various storage media. Then, when a predetermined period (for example, about several months to several years) elapses from the passage date and time, the information on the terminal 151 and the passage section relating to the passage date and time is deleted, thereby reducing the capacity load of the storage device and the storage medium. Can be suppressed.

  Further, the selection unit 117 includes a plurality of terminals 151 if the first terminal 151 located at the first position and the second terminal 151 located at the second position are sufficiently far from each other according to a predetermined reference. The number of terminals 151 that are located in the middle between the first position and the second position and that are stored in association with the corresponding section is sufficiently large on a predetermined basis. A lot of partitions are selected as target partitions.

  Among the plurality of terminals 151, a necessary condition for the target section to be selected for the first terminal 151 (terminal A) and the second terminal 151 (terminal B) is that the terminal A and the terminal B are sufficiently distant from each other. However, “sufficiently far” means that, when both the user X of the terminal A and the user Y of the terminal B try to approach each other, it is a relatively inexpensive public such as walking, bicycle, train or bus. It is the distance that can be encountered within a reasonable time (for example, several hours) by transportation.

  Further, the fact that the difference between the latest date and time collected for terminal A and the latest date and time collected for terminal B is less than or equal to a predetermined threshold (for example, about several hours to several days). "It may be imposed as a necessary condition."

  Note that if there is another terminal C located closer to the terminal B as viewed from the terminal A, the target section for the terminal A and the terminal B may not be selected.

  For example, the other terminal closest to the terminal A is the terminal B, the other terminal closest to the terminal B is the terminal A, and the separation distance between the terminal A and the terminal B is a predetermined threshold (for example, several kilometers to It is possible to adopt a mode in which target sections for terminal A and terminal B are selected on condition that the distance is about ten or more kilometers.

Further, another terminal in order of proximity to the terminal A, terminal _{B 1, B 2, B 3} , ... arranged as described above, when the nearest distance of the terminal B ₁ and the terminal A is equal to or higher than a predetermined threshold value, the terminal A a predetermined number of N (for example, about a few.) closer to the terminal B ₁ of ..., and each of B _N, and the terminal a, between, may select a target partition. For example, when the predetermined number is 2, the target section between the terminal A and the terminal B ₁ and the target section between the terminal A and the terminal B ₂ are selected.

  In the present embodiment, the first position (position P) where the first terminal 151 (terminal A) is located and the second position (position Q) where the second terminal 151 (terminal B) are located are sufficient. If the terminal 151 is located in the middle between the first position (position P) and the second position (position Q) from a plurality of sections, the terminal 151 stored in association with the section A section whose number counted without duplication is sufficiently large on the predetermined standard is selected as a target section.

  First, here, for example, the intermediate section located between the position P and the position Q is determined as follows.

  Most simply, the ratio of the distance from the position P and the distance from the position Q using a number A greater than a predetermined 1 is a circle of A to 1 (a circle with a distance ratio equal to A), And the section included in the common part U of the 1 to A circle (the circle whose distance ratio is equal to 1 / A that is the reciprocal of A) is the intermediate section located between the position P and the position Q. is there.

  The ratio between the distance between an arbitrary point in the common portion U and the position P and the distance between the point and the position Q is 1 / A to A.

  A circle drawn by a trajectory with a constant ratio of distance from two points is called an Apollonius circle. FIG. 3A is an explanatory diagram showing the intermediate region U when A = 2. FIG. 3B is an explanatory diagram showing the intermediate region U when A = 3. FIG. 3C is an explanatory diagram showing the intermediate region U when A = 5. As shown in these figures, as the value of A increases, the area of the common portion U (shaded portion) increases, and the edge approaches the position P and the position Q.

  A may be a constant (for example, about 2 to 3) or may be determined according to the length D of the line segment PQ (distance between the position P and the position Q) D and the like as follows. .

  For example, the distance between the position P and the intermediate section at the shortest distance from the position P can be calculated as D / (1 + A). Therefore, if this distance is considered to be equal to the distance S (for example, about 500 meters to several kilometers) that humans can traverse in a reasonable time, the number A is determined as A = D / S-1. Can do.

  In addition, a circle centered on the midpoint of the position P and the position Q and having a diameter of D / (1 + A) may be used as the intermediate region.

  In addition, a square having a center at the midpoint between the positions P and Q, a width and height of D / (1 + A), and a side parallel to the line segment PQ may be used as the intermediate area.

  In the present embodiment, a section in which many people can stay is selected as a target section among the intermediate sections determined in this way. Here, in the present embodiment, as a section where many people can stay, it is a condition that a sufficiently large number of people pass through the section at a sufficiently slow speed.

  The fact that a sufficiently large number of people are passing at a sufficiently slow speed is indicated by the fact that the number of terminals stored in the storage unit 116 for the section is counted more than a certain threshold. If only one terminal is stored for the section, the section is considered to be the home of the user who uses the one terminal, or to the school or commuting destination. If many terminals are stored, the section is considered as a public facility, store, or landmark where many people stop.If the terminal is not stored for the section, the section is This is because it is considered a place where no one can stop, such as an unexplored place in the mountains where no one has passed, or a highway.

  Therefore, the number of target sections that can be selected from the intermediate section between terminal A and terminal B closest to terminal A is an arbitrary number of zero or more.

  The number of target sections is 0 means that there is no place between the terminal A and the terminal B where the users of the terminal A and the terminal B gather. In such a case, instead of the terminal B, the terminal A may select the target section with the next closest terminal C. The same applies to terminal B.

  Then, the instructing unit 118 instructs the first terminal 151 and the second terminal 151 to present the selected target section.

  When a sufficient number of target areas are selected, the terminal 151 may present only a part of the target area and hide the rest in consideration of the privacy of the user of the other terminal 151. FIG. 4 is an explanatory view showing a display example on the screen of the terminal. In this figure, a self-machine mark 202 (rudder type) representing the position of the terminal itself is displayed at the center of the screen 201, and a plurality of target marks 203 (star shape) representing target areas are displayed around it. A user who wants to encounter another user sees this display and proceeds to one of the target marks 203.

  On the other hand, if there are a small number of selected target areas, it is considered that there are few public facilities, shops, landmarks, etc. that can be gathered in that area. In this case, even if all target areas are presented, The privacy of the other user is not compromised.

  In order for users of terminal A and terminal B to hesitate without invading each other's privacy, it is desirable for both users to move. For this reason, in this embodiment, when both users reach any one of the target sections, the target section may be selected again.

  As described above, there is a target section that is not displayed on the screen 201 of the terminal 151, and when both users reach one of such target sections, the target section is reselected. For this reason, even if the user has not arrived at the target section that the user wanted to go to, the target section is updated, and the place where an event that conflicts with other users occurs. In a conventional location game, an event usually occurs only at a target position fixed in advance, but in this embodiment, a place where users can gather sequentially moves to guide the user. It is possible to continue.

  When the server 101 detects that the terminal A and the terminal B are in the same section, the server 101 transmits an instruction to the terminal A and the terminal B to generate an event. The content of the event can be changed as appropriate according to the location game settings, such as collaborating with a common enemy character or allowing each other's terminals A and B to chat with each other and registering friends with each other. Is possible.

(Service processing)
The server 111 according to the present embodiment executes service processing in order to perform the above functions. FIG. 5A is a flowchart showing the first half of the control flow of service processing. Hereinafter, a description will be given with reference to FIG.

  When this process is started, the server 111 first receives a packet transmitted from each terminal 151 (step S300), and checks the type of the packet (step S301).

  As described above, this packet may represent position information transmitted from the terminal, or may represent other information.

  Here, in general, the latest position and the latest date and time are specified in the position information transmitted from the terminal. The latest position is typically expressed by the latitude and longitude of the position of the own device detected by the terminal 151 of the transmission source (hereinafter referred to as “terminal A” as appropriate). As the latest date and time, the date and time of detection designated in the position information is generally adopted, but the date and time when the position information is received may be used instead.

  When the received packet is location information transmitted from terminal A (step S301; location information), server 111 attempts to obtain the immediately preceding location and the immediately preceding date and time collected immediately before from terminal A from a storage device or the like. Is performed (step S302).

  If not acquired (step S302; No), the server 111 associates the identification name of the terminal A, the latest position, and the latest date and time and records them in a storage device or the like for a predetermined period (step S303). After collecting the position where the terminal A is located, the process proceeds to step S331.

  Even when the immediately preceding date / time is acquired, the difference from the latest date / time is a threshold value (for example, when the interval at which terminal A transmits position information to the server 111 is set to a few tens of seconds to a few minutes). If it is larger than several tens of minutes, it is possible to proceed to step S303 on the assumption that the immediately preceding date and time and the immediately preceding position could not be acquired.

  On the other hand, if acquisition is possible (step S302; Yes), the server 111 calculates the speed at which the terminal A has moved from the immediately preceding position, the immediately preceding date and time, the latest position, and the latest date and time (step S304).

  Then, the server 111 checks whether the speed of the terminal A is sufficiently slow based on a predetermined standard (step S305). If it is late (step S305; Yes), the server 111 extracts a passing section through which the route from the position immediately before terminal A to the latest position passes (step S306), and the terminal A passes through each extracted passing section. Estimate the date and time (step S307), associate each passing section with the identification name of terminal A and the passing date and time estimated for each passing section, and store them in a storage device or the like for a predetermined period (step S308) . Note that when a predetermined period elapses from the passage date and time related to the stored record, the record is deleted from the storage device (not shown).

  Then, based on the latest position collected for other terminals, a terminal that is sufficiently distant from terminal A is searched (step S309), and the following processing is performed for each of the found terminals (hereinafter referred to as “terminal B”). Is repeated (step S310). In an aspect in which only one terminal sufficiently far from terminal A is searched, the number of repetitions does not exceed one.

  That is, the server 111 checks whether or not the target section has already been selected for the pair of terminal A and terminal B (step S311), and if not selected (step S311; No), the latest of the terminal A A section that is located between the position and the latest position of the terminal B and that has a sufficiently large number of terminals stored in association with the section is selected as a target section. (Step S312).

  Then, the server 111 in the storage device or the like records the selection information representing the target section selected for the pair of the terminal A and the terminal B in the recording device or the like (step S313), and the terminal A and Terminal B is instructed to present the selected target section (step S314), and the process proceeds to step S315.

  On the other hand, if the target section has already been selected for the pair of terminal A and terminal B (step S311; Yes), the process proceeds to step S315.

  The server 111 repeats the processing of step S311-step S314 for each terminal sufficiently far from the terminal A (step S315), and then proceeds to step S303.

  On the other hand, if it cannot be said that the speed of the terminal A is sufficiently low (step S305; No), the process proceeds to step S303.

  As described above, the latest processing of recording the latest location and latest date and time of terminal A, and selecting and recording the target section with other terminals sufficiently far from terminal A if terminal A is sufficiently late When (Steps S302-S315) is completed, the server 111 executes the second half of the service process. FIG. 5B is a flowchart showing the second half of the control flow of service processing. Hereinafter, a description will be given with reference to FIG.

  That is, the server 111 extracts selection information related to the inclusion section that includes the latest position of the terminal A among the target sections selected for the terminal A (step S331). The selected partition may not be extracted, or only one may be extracted, or when the target partition is selected for each pair of terminal A and each of a plurality of other terminals, Multiple items may be extracted.

  Then, the server 111 adds information indicating that the terminal A has reached the target section to each of the extracted selection information (step S332) (step S333).

  Next, the server 111 checks whether or not information indicating that a terminal other than the terminal A has reached the target section is added to the selection information, that is, whether or not another terminal has arrived (step S334). . If not reached (step S334; No), the server 111 advances the control to step S342.

  On the other hand, if it has reached (step S334; Yes), the server 111 performs the selection related to the pair of the terminal A and another terminal (hereinafter referred to as “terminal B”) in the selection information. Information is erased from the recording device or the like (step S335).

  And the difference between the latest date and time collected for terminal A and the latest date and time collected for terminal B is a predetermined threshold (for example, about several minutes) or less, and the target section reached by terminal A, It is checked whether or not the section including the latest position collected for terminal B matches, that is, whether or not both terminals are close to each other (step S336).

  At this time, if the terminal A and the terminal B are close to each other (step S336; Yes), the server 111 instructs the terminal A and the terminal B to present that the event has occurred. (Step S337), after starting parallel execution of processing of an event caused by the close proximity of the terminal A and the terminal B (step S338), the process proceeds to step S342. The event processing can be executed in parallel by a lightweight process, thread, coroutine, or the like.

  On the other hand, if the two terminals are not close to each other (step S336; No), the processing corresponding to steps S312-S314 is executed (steps S339-S341), and the target section is selected again, and then the process proceeds to step S342. .

  After repeating the processing of steps S333-S341 for each of the extracted selection information (step S342), the server 111 returns control to step S300.

  If the received packet is not position information (step S301; other), the server 111 executes a corresponding process (step S351) and returns control to step S300.

  According to the present embodiment, it is possible to provide a motivation that allows users to meet each other even if they are users living in areas far from other users. In addition, the user's privacy can be taken into consideration by appropriately selecting the target section.

(Validity period)
An effective period can be provided for the target section selected in the above embodiment.

  For example, when a target section is selected for the combination of the first terminal 151 and the second terminal 151, a predetermined effective period (for example, about several tens of minutes to several hours) is set for the target section. Then, the selection unit 117 may perform selection again when the effective period has passed for a certain number of target sections or a certain ratio (for example, a majority).

  If both users continue to stay in the same section even after the validity period has elapsed, it is considered that both users are currently unable to participate in the location game. It may be performed after a certain amount of time (for example, about several tens of hours to several days) has elapsed.

  In addition, for the target section selected for the pair of terminal A and terminal B, if terminal A or terminal B is approaching the target section, the expiration date of the target section (for example, several minutes to several tens of minutes) Degree.) It may be extended. Whether or not the terminal is approaching the target section can be determined based on whether or not the distance between the latest position of the terminal and the target section is smaller than the distance between the immediately preceding position of the terminal and the target section.

  Further, when selecting the target section, it is possible to set an effective period according to the distance between the terminal A and the terminal B. For example, the longer the distance between the two, the longer the effective period may be.

  In addition, an effective period when the section is set as the target section can be set according to the number of sets of terminals having the section as the target section. For example, a mode is conceivable in which, as the number of sets of terminals having the section as the target section is larger, the effective period when the section is used as the target section is lengthened.

  In addition, the display mode of the target section displayed on the screen 201 of the terminal 151 can be changed according to the effective period in which the target section remains. For example, the longer the valid period, the larger the target mark 203, the darker the color, or the brighter the display so that the target section is more conspicuous. FIG. 6 is an explanatory diagram showing an example of displaying the target mark in a manner corresponding to the effective period of the target section. In the example shown in this figure, the target mark 203 is displayed larger as the remaining target section has a longer effective period.

  Thus, by providing the effective period in the target section, the user's target can be dynamically changed. Further, the user can refer to the aspect of the target mark 203 when making a strategy as to which target should be aimed.
