Also, since the photographer usually stops at a specific location to take pictures, there are cases where the accidental movement of the players and the ball, etc., causes objects that are not the object of observation to enter the shooting range, and the player and the ball that are the object of observation cannot be photographed. Furthermore, if the photographer's photography technique is inexperienced, the camera may not be able to capture the players and the ball accurately, and accurate information may not be collected.

[0004] To address the above-mentioned problems, Patent Document 1 proposes a system that collects information by using various sensors attached to athletes. Specifically, the system disclosed in Patent Document 1 includes various sensors (heart rate sensor, acceleration sensor) attached to the athletes, a communication device for each athlete, and a server device.

[0005] In the system disclosed in Patent Document 1, data collected by the sensors of each athlete is transmitted from the communication device to a server device, which stores the transmitted data for each athlete. [Prior art documents] [Patent documents]

[0014] (Embodiment) An example of an information processing device will be described below with reference to FIGS.

[0015] [Device configuration] First, a schematic configuration of an information processing device will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of a schematic configuration of an information processing device.

[0016] The information processing device 10 shown in Fig. 1 is a device for managing various information acquired from a plurality of terminal devices. As shown in Fig. 1, the information processing device 10 includes an information acquisition unit 11, an information management unit 12, and an inquiry response unit 13.

[0017] The information acquisition unit 11 acquires, from each of the multiple terminal devices, location information that identifies the location of the terminal device and motion information that identifies the motion state of the terminal device. The information management unit 12 manages the acquired location information and motion information for each of the multiple terminal devices in association with each other.

[0018] When an inquiry is made from an external device about some or all of the multiple terminal devices, the inquiry response unit 13 extracts the location information and movement information about the inquired terminal device from the managed location information and movement information. Then, the inquiry response unit 13 transmits the extracted location information and movement information to the external device.

[0019] In this way, the information processing device 10 can collect and manage the position information and motion information of each terminal device without using a camera. Also, the information processing device 10 can transmit the position information and motion information of the terminal device in response to an inquiry from the outside. In other words, if each athlete holds a terminal device, the information processing device 10 can collect data of the athlete without taking pictures with a camera and improve the convenience of the data.

[0020] Next, the configuration and functions of the information processing device 10 will be specifically described with reference to Figures 2 and 3. Figure 2 is a configuration diagram specifically showing an example of the configuration of the information processing device.

[0021] As shown in Fig. 2, the information processing device 10 is connected to a plurality of terminal devices 20 via a network 23 such as the Internet or a mobile phone communication network. In the example of Fig. 2, each terminal device 20 is held by an athlete 21 playing a sport. One of the terminal devices 20 is attached to a ball 22. Sports include ball games such as soccer, rugby, and basketball, and also field sports such as marathons. Furthermore, one of the terminal devices 20 is built into the ball.

[0022] 2, the terminal device 20 includes a receiving module of a satellite positioning system GNSS (Global Navigation Satellite System), such as a GPS (Global Positioning System) module. When the GNSS receiving module (hereinafter referred to as "GNSS module") receives radio waves from a plurality of artificial satellites 30, it calculates the position of the artificial satellite 30 and the distance to the artificial satellite 30 for each artificial satellite 30 using the received radio waves. Furthermore, the GNSS module calculates the position (latitude and longitude) of the terminal device 20 using the calculated distance to each artificial satellite 30 and the position.

[0023] The terminal device 20 generates position information using the position calculated by the GNSS module. The terminal device 20 also divides the difference between the position calculated by the GNSS module and the previously calculated position by the reception interval of the radio waves from the GNSS module to calculate the speed of the terminal device 20. The terminal device 20 then regards the calculated speed as the motion state of the terminal device 20 and generates motion information using the calculated speed.

[0024] 2, the terminal device 20 identifies the time when the terminal device 20 is in the position identified by the position information. Specifically, the terminal device 20 identifies the time of reception of the radio wave used to calculate the position information. The terminal device 20 also generates time information that identifies this time. The terminal device 20 then adds its own identification information to the time information, position information, and motion information, and transmits this information to the information processing device 10. Specifically, the terminal device 20 generates data for transmission including the time information, position information, motion information, and identification information, and transmits the generated transmission data for transmission.

[0025] In the embodiment, the terminal device 20 is not particularly limited as long as it has the above-mentioned information generating function and data transmitting function. An example of the terminal device 20 is a portable terminal device such as a smartphone. The terminal device 20 may be equipped with various sensors such as an acceleration sensor and a heart rate sensor in addition to or instead of the GNSS module. Furthermore, the terminal device 20 may be equipped with chips such as a GPS chip and a GNSS chip.

[0026] 2, the information processing device 10 includes a storage unit 14 in addition to the above-mentioned information acquisition unit 11, information management unit 12, and inquiry response unit 13. The information processing device 10 is also connected via a network to a terminal device 40 of a manager (e.g., a manager, a coach, etc.) 41 who manages the athletes.

[0027] In the embodiment, the information acquisition unit 11 receives data transmitted from each terminal device 20, and thereby acquires time information, location information, motion information, and identification information. The information acquisition unit 11 also transmits the time information, location information, motion information, and identification information to the information management unit 12.

[0028] In addition, in a competition, a spare ball may be prepared in addition to the ball used in the match, and in this case, the spare ball also has a built-in terminal device 20. Therefore, when the position information of ball 22 acquired from terminal device 20 indicates a position outside the competition field, information acquisition unit 11 deletes the position information of this ball because ball 22 is a spare ball.

[0029] The information management unit 12 manages the time information, position information, motion information, and identification information sent from the information acquisition unit 11 in association with one another. Specifically, as shown in Fig. 2, the information management unit 12 stores the time information, position information, and motion information in the storage unit 14 in an associated state for each terminal device 20 identified by the identification information.

[0030] Fig. 3 is a diagram showing an example of information for each terminal device stored by the information processing device. In the example of Fig. 3, the time, latitude, longitude, altitude, and moving speed are stored in the memory unit 14 for each identification number of the terminal device 20. In the example of Fig. 3, the memory unit 14 is constructed as a part of the information processing device 10, but is not limited to this example. The memory unit 14 may be constructed outside the information processing device 10.

[0031] When the administrator 41 makes an inquiry via the terminal device 40, the inquiry response unit 13 accepts the inquiry, extracts information corresponding to the accepted inquiry, and transmits the extracted information to the terminal device 40. This allows the inquiry response unit 13 to confirm the content of the inquiry.

[0032] Specifically, the terminal device 40 displays an input form for inquiries on its screen. The input form is provided with, for example, blank spaces for inputting the identification number of the terminal device (or the name of the athlete, etc.), blank spaces for inputting a time period, etc. When the administrator 41 inputs the identification number of the terminal device 20 to be inquired and the time period into the input form, the terminal device 40 transmits the input information to the information processing device 10.

[0033] When the information processing device 10 receives information from the terminal device 40, the inquiry response unit 13 identifies the identification number of the terminal device 20 that is the subject of the inquiry from the received information, and extracts the position information and movement information associated with the identified identification number from the storage unit 14. In addition, if the received information includes a time period, the inquiry response unit 13 extracts the position information and movement information for the corresponding time period. After that, the inquiry response unit 13 transmits the extracted information to the terminal device 40.

[0034] Furthermore, the inquiry response unit 13 can also generate information indicating changes in position and changes in motion status over time using, for example, time information, position information, and motion information for the inquired terminal device 20. In this case, the administrator 41 can identify the trajectories of movement of each of the players and the ball on the screen of the terminal device 40, and can identify the reasons for winning or losing the match.

[0035] [Device operation] Next, the operation of the information processing device 10 in the embodiment will be described with reference to Figures 4 and 5. In the following description, Figures 1 to 3 will be referred to as appropriate. Also, in the embodiment, an information processing method is implemented by operating the information processing device 10. Therefore, the description of the information processing method in the embodiment will be replaced with the following description of the operation of the information processing device 10.

[0036] First, a process from acquiring information from the terminal device 20 to storing it in the storage unit 14 will be described with reference to Fig. 4. Fig. 4 is a flow diagram showing an example of the operation of the information processing device from acquiring information to storing it.

[0037] First, as a premise, the terminal device 20 periodically generates position information using a position calculated by a GNSS module, and further calculates the speed of the terminal device 20 to generate motion information. The terminal device 20 also identifies the time when it is in a position identified by the position information, and generates time information that identifies this time. Then, the terminal device 20 transmits data for transmission including the time information, position information, motion information, and identification information.

[0038] As shown in FIG. 4, first, the information acquisition unit 11 receives data transmitted from each terminal device 20, and thereby acquires time information, position information, movement information, and identification information (step A1).

[0039] Next, the information management unit 12 associates the time information, position information, movement information, and identification information acquired in step A1 with one another, and stores this information in an associated state in the storage unit 14 (step A2).

[0040] Next, a process from receiving an inquiry from the terminal device 40 to responding to the inquiry will be described with reference to Fig. 5. Fig. 5 is a flow diagram showing an example of the operation of the information processing device when responding to an inquiry.

[0041] First, as a premise, the terminal device 40 of the administrator 41 displays an input form for inquiries on its screen. When the administrator 41 inputs the identification number of the terminal device 20 to be inquired, the time period, etc., into the input form, the terminal device 40 transmits the input information to the information processing device 10.

[0042] As shown in FIG. 5, when the information processing device 10 receives inquiry information from the terminal device 40, the inquiry handling unit 13 identifies the identification number and time period of the terminal device 20 that is the subject of the inquiry from the received information (step B1).

[0043] Next, the inquiry response unit 13 extracts, from the storage unit 14, the position information and movement information that are associated with the identification number identified in step B1 and that correspond to the time period identified in step B1 (step B2).

[0044] Next, the inquiry handling unit 13 then transmits the information extracted in step B2 to the terminal device 40 (step B3).

[0045] After step B2 is executed, the inquiry response unit 13 can also generate information indicating a change in position and a change in motion state along a time series by using the time information, the position information, and the motion information for the inquired terminal device 20. In this case, in step B3, the inquiry response unit 13 transmits information indicating a change in position and a change in motion state along a time series to the terminal device 40.

[0046] By executing step B3, information about the inquired terminal device 20 is displayed on the screen of the terminal device 40. The manager 41 analyzes the content of the match based on the displayed information.

[0047] As described above, the information processing device 10 can collect and manage data of each athlete (terminal device 20) without using a camera, improving the usability of the obtained data. As a result, the accumulated data can be used as big data for further analysis and strategy research. For example, data on all players participating in all games of a team in a sports competition can be accumulated over a long period of time, so that the strengths and weaknesses of each player can be identified and the team as a whole can be strengthened.

[0048] In the above example, the terminal device 20 transmits the position information, the motion information, the time information, and the identification information to the information processing device 10 at any time, but the present invention is not limited to this example. For example, the terminal device 20 can store the position information, the motion information, the time information, and the identification information within a certain period of time in its own storage device, and later transmit the stored information as a whole to the information processing device 10.

[0049] [program] An example of the program is a program that causes a computer to execute steps A1 to A2 shown in Fig. 4 and steps B1 to B3 shown in Fig. 5. By installing and executing this program in a computer, the information processing device 10 and the information processing method in the embodiment can be realized. In this case, the processor of the computer functions as the information acquisition unit 11, the information management unit 12, and the inquiry response unit 13 and performs the processing. Examples of the computer include a general-purpose PC, a smartphone, and a tablet terminal device.

[0050] In the present embodiment, the storage unit 14 can be realized by a storage device such as a hard disk provided in the computer, or the like. The storage unit 14 may be realized by a storage device of another computer.

[0051] The program may be executed by a computer system constructed by a plurality of computers. In this case, for example, each computer may function as any one of the information acquisition unit 11, the information management unit 12, and the inquiry response unit 13.

[0056] Moreover, the program in the embodiment is provided in a state stored in a computer-readable recording medium 120. The program in the embodiment may be distributed on the Internet connected via the communication interface 117.

[0057] Specific examples of the storage device 113 include a hard disk drive and a semiconductor storage device such as a flash memory. The input interface 114 mediates data transmission between the CPU 111 and input devices 118 such as a keyboard and a mouse. The display controller 115 is connected to a display device 119 and controls the display on the display device 119.

[0058] Data reader / writer 116 mediates data transmission between CPU 111 and recording medium 120, reads programs from recording medium 120, and writes processing results in computer 110 to recording medium 120. Communication interface 117 mediates data transmission between CPU 111 and other computers.
