Description

[Technical field]

[0001] The present invention relates to a system [Background technology]

[0002] There are known information processing devices that display speed measurement results relating to sports. Patent Document 1 discloses an information processing device that displays speed measurement results for golf. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-152291 A Summary of the Invention [Problem to be solved by the invention]

[0004] One of the objects of the present invention is to provide a new technology that, for example, increases the convenience of sharing the results of measurements of a specific object used in a specific sport conducted by a measurement device with users of communication terminals located in the vicinity of the measurement device.

[0005] The purpose of the present invention is not limited to this, and the applicant intends to obtain rights for configurations that aim to obtain effects from parts of the configurations disclosed in this specification and drawings, etc., by filing a divisional application, amendment, etc. For example, this specification discloses a problem in which the part described as "can be" in this specification is read as "the problem is to be". The problems are described as being independent, and the applicant intends to obtain rights for the configurations for solving each problem separately by filing a divisional application, amendment, etc. Even if the problems are implicitly understood from the description in the specification, the applicant intends to include part of the configurations described in this specification in the scope of the patent claim by amendment or divisional application. In addition, the applicant has disclosed a configuration that solves a problem that combines these independent problems, and intends to obtain rights for it. [Means for solving the problem]

[0006] In order to solve the above problems, for example, the following configuration is adopted. The present application includes a plurality of means for solving the above problems, and an example thereof is as follows.

[0007] (1) It is preferable to provide a system comprising a measuring device and a plurality of communication terminals, the measuring device having a function of performing measurements on a specified object used in a specified sport, a function of detecting one or more first communication terminals that are present within a specified range of the plurality of communication terminals by performing broadcast communication using a specified wireless communication method, and a function of transmitting measurement data indicating a result of the measurement to each of the one or more detected first communication terminals when the measurement is performed, the plurality of communication terminals having a function of receiving the measurement data transmitted to the communication terminal by the measuring device, and a function of performing a display based on the received measurement data.

[0008] In this way, it is possible to improve the convenience when the measurement result of a predetermined object used in a predetermined sport performed by the measurement device is shared with users of communication terminals around the measurement device. In particular, since the measurement device transmits measurement data to each of the first communication terminals detected by broadcast communication using a predetermined wireless communication method, the measurement result can be shared without the user of the measurement device or communication terminal setting up pairing between the measurement device and the communication terminal in advance. In addition, in a sport, there are often multiple people such as the athlete's family, manager, coach, and teammates near the athlete, and as a result, there are often multiple (for example, many) communication terminals used by each person. In such a case, since the measurement data is transmitted to each person's communication terminal, it is possible to easily realize sharing of the measurement result among multiple people near the athlete. In addition, since it is considered that the measurement result of the object rarely contains highly confidential information, the advantage of prioritizing the assurance of user convenience over the viewpoint of privacy, etc., when sharing with users of communication terminals is great.

[0009] The predetermined competition may be a sports competition, and in particular, may be baseball or softball. The object may be a tool used in the competition, and in the case of a sports competition, it may be a sports tool, and in the case of baseball or softball, it may be a ball or a bat. The object may be something other than a tool used in the competition, and may be a body part of the athlete playing the competition (for example, the athlete's arm or leg). The sports competition may be a competition other than baseball or softball, and may be a ball game such as golf or tennis, or a track and field event (for example, a short distance run). The broadcast communication may be a so-called advertising communication, and in particular, BLE (Bluetooth Low Energy) is used as the wireless communication method. The measurement data showing the result of the measurement may be transmitted to the communication terminal immediately after the measurement and displayed, and in particular, it is particularly preferable that the measurement data is transmitted in real time and displayed on the communication terminal. The measurement data may be transmitted for a predetermined time after the measurement. The measurement device may be a device specialized in measuring the object, and in particular, it is particularly preferable that the measurement device has a function as a speed gun that measures the speed of the object. The communication terminal may be a general-purpose terminal that is not specialized for displaying the results of measurements on the target object, and is particularly suitable as a portable communication terminal such as a smartphone or tablet computer.

[0010] (2) The objects include a first object and a second object, and the measurement function is set to either a first mode for measuring the first object or a second mode for measuring the second object, and performs measurements. When the display function is switched between the first mode and the second mode, it is preferable that the display function switches the mode of a screen that displays based on the measurement data depending on the mode after the switch.

[0011] In this way, when the measuring device has a function of switching modes according to the object to be measured, the display mode of the screen of the communication terminal can be switched without an explicit instruction from the user, thereby reducing the operations that the user must perform and improving user convenience. It is particularly preferable that the first object and the second object are different objects used in the same sport. In the case of baseball or softball, it is particularly preferable that the first object is a ball and the second object is a bat.

[0012] (3) The measurement device has a first display unit and a function of displaying the results of the measurement on the first display unit, and each of the multiple communication terminals has a second display unit capable of displaying information in a wider variety of ways than the first display unit, and the display function may be to display information based on the received measurement data on the second display unit.

[0013] In this way, the user can grasp the measurement results not only by looking at the first display unit of the measuring device, but also by looking at the second display unit of the communication terminal, which is capable of displaying a wider variety of information. For example, since the measuring device is installed so that it can measure an object, it may be difficult for users such as athletes to see the first display unit, but the measurement results can be grasped from the more easily visible second display unit. Furthermore, if the second display unit is configured to display information in a wider variety of expressions than the first display unit, the measurement results can be displayed with higher quality. The higher quality may be achieved by increasing the quality of the content of the information to be displayed, such as by increasing the number of items of information to be displayed, or by increasing the quality of visibility, such as by increasing the number of colors to be displayed. It is particularly preferable to use a black and white display unit as the first display unit and a color display unit as the second display unit.

[0014] (4) The second display unit has a rectangular display area, and the display function is such that, when the communication terminal is in a first position in which the longer side of the display area is vertical, a display based on the measurement data is displayed in each of a plurality of regions into which the display area is vertically divided, and when the communication terminal is in a second position in which the shorter side of the display area is vertical, a display based on the measurement data displayed in one of the plurality of regions is enlarged compared to when the communication terminal is in the first position.

[0015] In this way, the user can view the display based on the measurement data on the second display unit having a rectangular display area in a manner suitable for the posture of the communication terminal. The first posture is a posture that is likely to be taken when the user holds the communication terminal in his / her hand, and allows the user to simultaneously view and grasp the contents of multiple items of information. The first posture is an example of a posture that performs so-called vertical screen display. The first posture is based on the knowledge that the first posture is particularly likely to be taken in communication terminals used by users other than athletes during a competition. The second posture is a posture that is likely to be taken when the user places the communication terminal in a predetermined location, and although the distance from the user may be relatively large, the contents of the information can be easily grasped by the enlarged display. The second posture is an example of a posture that performs so-called horizontal screen display. The second posture is based on the knowledge that the second posture is particularly likely to be taken in communication terminals used by athletes during a competition.

[0016] (5) The second display unit has a rectangular display area, and the display function is to display detailed information based on the measurement data when the communication terminal is in a first position in which the long side of the display area is vertical, and to display information for athletes participating in the competition when the communication terminal is in a second position in which the short side of the display area is vertical.

[0017] In this way, the user can view the display based on the measurement data on the second display unit having a rectangular display area in a manner suitable for the posture of the communication terminal. The first posture is a posture that is likely to be taken when the user holds the communication terminal in his / her hand, and allows the user to grasp detailed information based on the measurement data. The first posture is an example of a posture that performs so-called portrait screen display. The first posture is based on the knowledge that the first posture is particularly likely to be taken in communication terminals used by users other than athletes during a competition. The second posture is a posture that is likely to be taken when a user places the communication terminal in a predetermined location, and is based on the knowledge that the second posture is particularly likely to be taken in communication terminals used by athletes during a competition. The second posture is an example of a posture that performs so-called landscape screen display.

[0018] (6) The transmitting function may transmit the measurement data for a predetermined period of time when the measurement is performed, and transmit the measurement data corresponding to the next measurement for a predetermined period of time when the next measurement is performed, and the displaying function may display based on the most recent measurement data received.

[0019] In this way, the communication terminal displays information based on the most recent measurements, making it easier for the user of the communication terminal to intuitively understand, while watching the competition, which of the athlete's movements the communication terminal is displaying information based on the measurements that correspond to that movement.

[0020] (7) Each of the plurality of communication terminals has a function of acquiring imaging information from an imaging unit while the competition is being held and a function of recording the measurement data and the imaging information in association with each other, and the display function may be to simultaneously display based on the recorded measurement data and the imaging information using the first display unit.

[0021] In this way, the user can simultaneously view the imaging information showing the contents captured by the imaging unit while the competition is taking place and the results of measurements taken during the competition. The user can correlate the state of the object and its surroundings while the competition is taking place with the results of the measurements, and can therefore use this display to, for example, check the form of the athlete and consider ways to improve it.

[0022] (8) The function of performing measurements may perform measurements on the object using a microwave Doppler sensor.

[0023] In this way, the user can use the communication terminal to view the results of measurements made by a measuring device that uses a microwave Doppler sensor to measure an object.

[0024] (9) The sport may be baseball or softball, and the display based on the measurement data may include the speed of the ball, which is the object, and a predicted speed at which it will reach home base.

[0025] In this way, the user can know the speed of the ball used in baseball or softball, which is the predicted speed at which the ball will arrive at home base. The user can grasp the predicted speed at which the ball is moving at the position of home base, and can grasp more detailed information about the ball's speed than ever before. The predicted speed at which the ball will arrive at home base may be displayed by the measurement device, but by displaying it only on the communication terminal and not on the measurement device, it is expected to improve the functionality of the communication terminal (for example, a program having a function of displaying based on measurement data) and further promote the use of the communication terminal and the program having a function of displaying based on the measurement data.

[0026] (10) The measurement result may include a distance traveled by the ball, and the display function may be configured to not display the predicted speed if the distance traveled is outside a predetermined distance range.

[0027] In this way, when the ball moves outside the predetermined distance range, the user is less likely to misunderstand the predicted arrival speed to home base. The predetermined distance range may be a range based on the expected ball movement distance in baseball. For example, when the ball movement distance is extremely long or extremely short, the deviation from the expected distance in baseball may cause a decrease in the quality of the predicted arrival speed to home base. This is based on the knowledge that such measurement results should not be provided to the user.

[0028] (11) It is desirable to provide a measurement device having the following functions: a function of performing measurements on a specified object used in a specified sport; a function of detecting one or more first communication terminals that are present within a specified range of a plurality of communication terminals by performing broadcast communication using a specified wireless communication method; and a function of transmitting measurement data indicating the results of the measurement to each of the one or more detected first communication terminals upon the measurement.

[0029] This increases the convenience of sharing the results of measurements taken by the measuring device regarding a specific object used in a specific sport with users of communication terminals located in the vicinity of the measuring device.

[0030] (12) It is preferable to provide a communication terminal that communicates with a measuring device having a function of performing measurements on a specific object used in a specific sport via a specific wireless communication method, the communication terminal having the following functions: when data transmitted by broadcast communication via the wireless communication method from the measuring device is received, the communication terminal has a function of establishing a communication connection with the measuring device, a function of receiving measurement data indicating the results of the measurement on the object that is transmitted to the communication terminal after the communication connection is established, and a function of performing a display based on the received measurement data.

[0031] This increases the convenience of sharing the results of measurements taken by the measuring device regarding a specific object used in a specific sport with users of communication terminals located in the vicinity of the measuring device.

[0032] (13) It is preferable to provide a program for causing a computer to realize the functions of the above-mentioned measuring device.

[0033] (14) It is preferable to provide a program for causing a computer to realize the functions of the above-mentioned communication terminal.

[0038] Hereinafter, the embodiments will be described in detail with reference to the drawings. The embodiments shown below are examples of the embodiments of the present invention, and the present invention is not limited to these embodiments. In the following description, labeling using numerical values ​​such as 1, 2, ... is for identifying each element, and does not determine the number of elements. In the drawings referred to in this embodiment, the same parts or parts having similar functions are given the same or similar symbols (symbols with A, B, etc. added after the numbers), and repeated explanations may be omitted. In addition, in each drawing referred to in the following description, the scale may be different from the actual scale in order to make each member, each area, etc. recognizable.

[0039] [1. Overall composition] FIG. 1 is a diagram showing the overall configuration of a system 1. FIG. 1 shows the entire system 1 as viewed from above. The system 1 has a plurality of measuring devices 10 and a plurality of communication terminals 20. In this embodiment, the measuring devices 10 are assumed to be measuring devices 10A and 10B. In FIG. 1, the main bodies of the measuring devices 10A and 10B are installed in a state where they are attached to tripods. In this embodiment, the communication terminals 20 are assumed to be communication terminals 20A, 20B, 20C, 20D, 20E, and 20F.

[0040] The measuring device 10 is a device specialized for performing measurements on a predetermined object used in a predetermined sport. The predetermined sport is a sports competition, and in this embodiment, it is baseball or softball. Measurements during a sport may be performed during the actual game (match) of the sport, or during practice, as long as the use of the measuring device 10 is not a problem. In other words, measurements may be performed in a situation in which the sport is being played. The object is a tool used in the sport, and in this embodiment, it is a ball or a bat used in baseball or softball. The measuring device 10 is a device that has a function of displaying the ball speed and bat swing speed of baseball, softball, etc. The measuring device 10 may be a device that is understood as a device called a speed gun. The measuring device 10 performs measurements using a microwave Doppler sensor, and measures the speed of the object, etc., based on the Doppler signal output from the microwave Doppler sensor.

[0041] 2 is a diagram for explaining measurement items handled by system 1. Measurement device 10 has, as measurement modes, a pitching mode (an example of a first mode) and a batting mode (an example of a second mode).

[0042] An overview of the pitching mode-related measurements performed by the measurement device 10 will now be described. The player P11 is a pitcher. The player P12 is a catcher. The player P13 is a batter. The measuring device 10A is installed near the player P11, for example, slightly diagonally behind the player P11 to the left. The measuring device 10A measures the ball speed of the ball 30A, which is the first object, and the distance of the section traveled by the ball 30A. The ball speed includes an initial speed and a final speed (unit: km / h). The distance of the section traveled by the ball 30A is the distance (unit: m) between the initial speed point where the initial speed is measured and the final speed point where the final speed is measured. Therefore, the distance of the section traveled by the ball 30A may be referred to as the "initial speed-final speed distance" below. This initial speed-final speed distance is generally understood as the distance between the player P11 and the player P12 or P13. 2 indicates the predicted speed of the ball 30A at the home base, but in this embodiment, this is not an item measured by the measuring device 10 but is an item displayed on the external communication terminal 20. Details will be described later.

[0043] An overview of measurements related to the batting mode in the measurement device 10 will be described. The measuring device 10B is installed near the players P12 and P13, for example, behind the players P12 and P13, and measures the speed (unit: km / h) of the bat 30B, which is a second object. The measuring device 10B measures the swing speed (also called the bat speed) of the bat 30B when the player P13 takes a practice swing and when he misses. When the player P13 hits the ball 30A with the bat 30B, the measuring device 10B further measures the speed (unit: km / h) of the ball 30A (hit ball) immediately after impact (immediately after being hit) and an approximate flight distance (unit: m) of the ball 30A (hit ball).

[0044] Returning to FIG. The communication terminal 20 is a communication terminal having a function of performing wireless communication with the measuring device 10 by a predetermined wireless communication method. The communication terminal 20 has a function of displaying the results of measurement by the measuring device 10 based on information acquired by communication from the measuring device 10. In this embodiment, the communication terminal 20 is a smartphone or a tablet computer, each having a rectangular display area. The communication terminal 20 may be a communication terminal other than these, but it is preferable that the communication terminal 20 is a terminal that is not specialized for displaying the results of measurement of an object by the measuring device 10 and is used for general purposes. The communication terminal 20 may be a smartphone or a tablet computer, or may be, for example, a portable communication terminal such as a feature phone or a wearable terminal.

[0045] In this embodiment, the communication terminal 20A is a smartphone carried and used by the user U21. The communication terminal 20B is a smartphone carried and used by the user U22. The communication terminal 20C is a smartphone carried and used by the user U23. In a competition, there are often multiple people such as the athlete's family, manager, coach, and teammates near the athlete. The users U21 to U23 are people other than the athlete who are near the athlete (hereinafter, sometimes referred to as "related parties"). The communication terminal 20D is a tablet computer used by the athlete P11 while being placed near the athlete. For example, when practicing pitching or checking his / her pitching form, the athlete P11 places the communication terminal 20D near the athlete and checks the measurement results by looking at the communication terminal 20D. The communication terminals 20E and 20F are smartphones carried and used by third parties other than the athlete and related parties.

[0046] The location area T1 shown in FIG. 1 is a virtual representation of a predetermined location where a sport is played. The location area T1 is specified by a communication area where the measuring device 10 can perform wireless communication by the wireless communication method. Therefore, the location area T1 can change depending on the communication method of wireless communication performed by the measuring device 10, the strength of radio waves used for wireless communication, and the presence of objects (e.g., buildings) that obstruct radio wave propagation. The location area T1 shown in FIG. 1 is assumed to be an area where wireless communication is possible with each of the measuring devices 10A and 10B. The location area T1 may include an area where the sport is actually played in a place where the sport is played, such as a ground, a sports field, or a stadium, and its surrounding areas. For example, if the sport is baseball, the area where the sport is actually played may include at least the infield and the outfield. It is particularly preferable that the surrounding area includes the foul zone, and further includes benches around it and an area where spectators' seats are present. In this embodiment, a case will be described in which the measuring device 10 has a function of performing wireless communication by BLE (Bluetooth Low Energy) as a wireless communication method. In this case, the location region T1 is, for example, a region at a distance of approximately several tens of meters to a hundred meters from the measuring devices 10A and 10B.

[0047] Fig. 3 is a diagram showing the configuration of the measuring device 10. Fig. 3(A) shows a photograph of the measuring device 10 in a normal use posture taken from diagonally above to the right. Fig. 3(B) is a block diagram showing the electrical configuration of the measuring device 10.

[0048] As shown in Fig. 3(A), measuring device 10 has a flat, approximately rectangular parallelepiped exterior configuration. In normal use, measuring device 10 is set up so that the surface on which display unit 14 and operation unit 17 are arranged faces upward. Display unit 14 of measuring device 10 is visible to athletes and those around them. Operation unit 17 is operated by athletes P11-P13 and those around them. Measuring device 10 operates using a battery (not shown) as a power source.

[0049] As shown in FIG. 3B, the measuring device 10 includes a microwave Doppler sensor 11, an amplifier 12, a control unit 13, a display unit 14, a storage unit 15, a communication unit 16, and an operation unit 17. The microwave Doppler sensor 11 is a sensor for transmitting microwaves toward an object and calculating the speed of the object based on a Doppler signal, which is a wave reflected from the object. The amplifier 12 amplifies the Doppler signal output from the microwave Doppler sensor 11. The control unit 13 may be a microcomputer including a CPU, a ROM, a RAM, an I / O, and the like. The control unit 13 realizes various functions by executing a program stored in the ROM or the storage unit 15. The control unit 13 has a function of controlling each unit of the measuring device 10. The control unit 13 performs measurements on the object based on the output of the amplifier 12. The measurement process may include a process for calculating the speed of the object and a process for calculating the distance of the section traveled by the object (the distance between the initial speed and the final speed). Furthermore, the control unit 13 performs a process of displaying the measurement result on the display unit 14, a process of storing the measurement result in the memory unit 15, and a process of transmitting measurement data indicating the measurement result using the communication unit 16. The measurement data is transmitted to a communication terminal 20 (in this embodiment, communication terminals 20A to 20D, an example of a first communication terminal) that is present within the location region T1, among the multiple communication terminals 20.

[0050] The display unit 14 is an example of a first display unit disposed in the center of the top surface of the measuring device 10. In this embodiment, the display unit 14 is a display unit that displays in black and white and does not have a function of displaying in color (multi-color). The display unit 14 is, for example, a dot matrix liquid crystal display panel. The display unit 14 may be configured to have a segment display, for example, a seven-segment display used in a product called a golf swing trainer manufactured and sold by the applicant.

[0051] The storage unit 15 stores data. The storage unit 15 is, for example, a flash memory. The storage unit 15 may be a built-in storage means of the measurement device 10, but may also be an external storage means such as a USB memory or a memory card (for example, an SD card). For example, a memory card reader constituting the storage unit 15 may be provided on the side of the measurement device 10.

[0052] The communication unit 16 performs wireless communication with a communication terminal 20 that is present within a predetermined range from the measurement device 10 according to a predetermined wireless communication method. The communication unit 16 has a function of performing wireless communication with one or more communication terminals 20 without receiving a user's operation to set a communication partner, more specifically, without setting up pairing with the communication terminal of the communication partner. In this embodiment, the communication unit 16 has a function of performing wireless communication by BLE.

[0053] The control unit 13 also performs processing in response to the operation of the operation unit 17. The operation unit 17 is disposed closer to the user than the display unit 14. The operation unit 17 may include a power button, a start / stop button, a cross key, and a set button. The power button is a button for switching the power of the measurement device 10 on and off, and is disposed in a position closer to the left as viewed by the user. The start / stop button, the cross key, and the set button are disposed in a position closer to the right than the power button as viewed by the user. The cross key is disposed with the set button at the center, with an up button at the 0 o'clock position for indicating an up direction, a right button at the 3 o'clock position for indicating a right direction, a down button at the 6 o'clock position for indicating a down direction, and a left button at the 9 o'clock position for indicating a left direction. The start / stop button is a button for instructing the start (start) and stop (stop) of measurement by the measurement device 10, and is disposed in a position farther back than the cross key and the set button as viewed by the user.

[0054] The measurement device 10 is set to either a pitching mode or a batting mode (also called a detection mode) and performs measurements on the object.

[0055] An example of a method for setting a mode (detection mode) will be described with reference to FIG. 4. When the power button is operated to turn on the power of the measuring device 10, the control unit 13 displays a "main menu screen" on the display unit 14 when the power is turned on for the first time, as shown in the "2-1" column of FIG. 4. The control unit 13 can change the mode to be selected according to the operation of the up and down buttons of the operation unit 17. As shown in the "2-2" column of FIG. 4, when a press of the set button is detected with one of the modes selected, the control unit 13 sets the selected mode. Note that, if a screen such as each measurement mode was displayed at the time of the previous termination, information on which screen was displayed when the power was turned off is stored, and the screen displayed at the time of the previous power off is displayed based on this stored information, and a process corresponding to that screen is executed.

[0056] FIG. 5 is a diagram illustrating a display screen of the measurement results in the measurement device 10. As shown in FIG. The pitching mode is a mode for making measurements related to the ball 30A, and is a mode for making measurements related to pitching using the ball 30A. The batting mode is a mode for making measurements related to the bat 30B, and is a mode for making measurements related to batting using the bat 30B. The pitching mode and the batting mode may be the same as those described in Patent Document 1, but a brief explanation is as follows.

[0057] The pitching mode is a specialized mode for measuring the ball speed of ball 30A. Control unit 13 measures the initial velocity of the ball, the final velocity of the ball, and the distance between the initial velocity and the final velocity, which is the distance between the points where the initial velocity and the final velocity are measured. In the pitching mode, as shown in FIG. 5, control unit 13 displays an icon display unit in the upper area of ​​display unit 14, and displays the initial velocity of ball 30A, the final velocity of ball 30A, and the distance between the initial velocity and the final velocity below it.

[0058] More specifically, in the measurement process in pitching mode, the control unit 13 performs measurement with a time within the range of the ball's speed as one unit, and displays the measurement results obtained within the period of one unit. For example, the control unit 13 performs frequency analysis on the Doppler signal output from the amplifier 12 to calculate the repeated speed, records the repeatedly calculated speed in RAM, and generates display information (measurement results) to be displayed in the one unit based on the history of the recorded speeds. The initial speed displays the ball speed first detected as a moving object. The final speed displays the ball speed just before it can no longer be detected as a moving object. The interval displays the distance between the initial speed and the final speed. When only the instantaneous speed can be detected, such as when the interval in which the speed is detected is short, the interval is displayed as "0" or "- - -". Each time one unit is measured, the obtained values ​​are displayed in a flashing manner for the time set in the system settings (initial value is 3 seconds), and after this fixed time has elapsed, the display of the obtained values ​​is changed from flashing to on to notify that the detection results have been updated. The blinking time of the speed display (initial value: 3 seconds) can be changed in the system settings. The detection results are recorded in the non-volatile memory of the control unit 13 of the measuring device 10 up to 200 cases together with the record number. Therefore, even if the battery is removed or the battery is depleted, the records of the detection results are not erased. After that, it is determined whether the detection method set and stored in the control unit 13 is "one time" or "continuous". If it is "one time", the measurement process is terminated and the currently displayed screen is displayed, whereas if it is continuous, the measurement process of the pitching mode is performed again (i.e., the measurement of the next unit is started). During these processes, it is detected whether the start / stop button has been pressed, and if it is detected that the start / stop button has been pressed, the measurement process is terminated and the currently displayed screen is displayed.

[0059] Next, the batting mode will be described. The batting mode is a specialized mode for measuring the batting speed of baseballs and softballs. The control unit 13 measures the bat swing speed, the initial velocity of the batted ball, and the estimated flight distance of the batted ball. In the batting mode, as shown in FIG. 5, the control unit 13 displays an icon display section in the upper area of ​​the display unit 14, and displays the bat swing speed, the initial velocity of the batted ball, and the estimated flight distance of the batted ball below the icon display section.

[0060] More specifically, in the measurement process in the batting mode, the control unit 13 measures the bat swing speed, the initial velocity of the batted ball, and the time within the range of the speed of the bat's hitting motion as one unit, and displays the measurement results obtained within one unit period. The flying distance is calculated based on the speed of the batted ball under the conditions of "angle of the batted ball: 45 degrees" and "height of the hitting point: 1m". Note that the flying distance is based on the ball hit toward the center, and there may be a large error in the ball hit toward the first base or third base. The bat swing speed (bat) and the initial velocity of the batted ball (batted ball) are calculated by, for example, a known method. If the initial velocity of the batted ball (batted ball) is not detected, the initial velocity of the batted ball (batted ball) and the estimated flying distance of the batted ball (flying distance) are not displayed. That is, when the ball is hit back or knocked, the bat swing speed (bat), the initial velocity of the batted ball (batted ball), and the estimated flying distance of the batted ball (flying distance) are measured and displayed. When the bat swings or whiffs a ball, the bat swing speed (bat) is measured and displayed. Each time a measurement unit is performed, the obtained values ​​are displayed in a blinking manner for the time set in the system settings (initial value is 3 seconds), and after this fixed time has elapsed, the display of the obtained values ​​changes from blinking to a steady light to indicate that the detection results have been updated. The blinking time of the speed display (initial value: 3 seconds) can be changed in the system settings. The detection results are recorded in the non-volatile memory of the control unit 13 of the measurement device 10 up to 200 cases together with the record number. The control unit 13 judges whether the detection method set and stored is "one time" or "continuous", and if it is "one time", the measurement process is terminated and the currently displayed screen is displayed, whereas if it is continuous, the measurement process in the batting mode is performed again (i.e., the measurement of the next unit is started).

[0061] Next, the icon display section will be described with reference to FIG. As shown in FIG. 6, the icon display section has, from left to right, (1) a battery remaining capacity display section, (2) a mode display section, (3) a recording status display section inside the device, and (4) an SD card display section. (1) The battery remaining capacity display section displays the remaining battery capacity in two stages as an icon when the measuring device 10 is being used with a battery. (2) The mode display section displays icons indicating the current mode, such as pitching mode, batting mode, speed detection in progress, and system setting mode. (3) The recording status display section inside the device displays an icon indicating that the recording capacity of the measurement data storage area of ​​the RAM of the control section 13 is full. (4) The SD card display section does not display anything when a memory card (e.g., a microSD card) as the storage section 15 is not inserted, displays the icon "SD" when a microSD card is inserted, and displays the icon "FULL" when the storage capacity of the microSD card is full.

[0062] FIG. 7 is a diagram illustrating the system setting menu screen. For example, when the "System Setting" menu shown in FIG. 4 is selected and the set button is pressed, the control unit 13 displays a system setting menu screen on the display unit 14. The system setting menu screen is a screen that displays each of the menus "Auto Power Off Time", "Blink Time", "Contrast", "Initialization", and "System Information" as shown in FIG. 7. When any of the menus is selected and the set button is pressed, the control unit 13 displays a screen for setting as described in FIG. 7 on the display unit 14, and performs various settings according to the user's operation. When the "System Information" menu is selected and the set button is pressed, the control unit 13 displays an identification number unique to the measurement device 10 itself. The identification number is, for example, in the format of "BSG BLE_xxxxxx", where the character string in the "xxxxxxxxx" part differs depending on the individual measurement device 10. It is preferable that the character string in the "xxxxxxxxx" part is a combination of letters and numbers, and is assigned so that it is not duplicated at least among multiple measurement devices 10 used simultaneously. In particular, the identification number may be a character string that includes the last three bytes of the MAC address of the BLE module used in the communication unit 16 in addition to the character string “BSG BLE_”.

[0063] 3. Configuration of communication terminal 20 Fig. 8 is a block diagram showing an electrical configuration of the communication terminal 20. As shown in Fig. 8, the communication terminal 20 includes a control unit 21, a voice input / output unit 22, a communication unit 23, a UI (User Interface) unit 24, a storage unit 25, a posture sensor 26, and an imaging unit 27.

[0064] The control unit 21 controls each part of the communication terminal 20. The control unit 21 includes a computer having a CPU, a ROM, and a RAM. The CPU reads out a program stored in the ROM or the storage unit 25 into the RAM and executes it to control each part of the communication terminal 20. The audio input / output unit 22 includes a microphone and a speaker, and realizes a function related to audio input / output in the communication terminal 20. The communication unit 23 includes, for example, a wireless communication circuit and an antenna, and is an interface for performing wireless communication. The communication unit 23 has a function of performing wireless communication (BLE wireless communication in this embodiment) at least with the measurement device 10. The UI unit 24 includes, for example, a touch panel unit, and accepts operations from a user and notifies information by displaying an image. The UI unit 24 has a rectangular display unit (an example of a second display unit). The UI unit 24 is configured to be able to display information in a more diverse manner than the display unit 14 of the measurement device 10, and is particularly capable of displaying information in multiple colors and displaying images such as photographs. The UI unit 24 may have, for example, a liquid crystal display, and may have a display unit made up of a plurality of pixels arranged two-dimensionally in a grid pattern.

[0065] The storage unit 25 includes, for example, an EEPROM (Electrically Erasable Programmable ROM), and stores an OS and an application 251 that runs on the OS as a program executed by the control unit 21. The application 251 is an application program for implementing various functions by communicating with the measurement device 10. The function of the application 251 may be implemented by a program other than firmware or an application program.

[0066] The attitude sensor 26 is a sensor that detects the attitude of the communication terminal 20. The attitude sensor 26 is a sensor for detecting at least whether the communication terminal 20 is in a vertical or horizontal orientation. The vertical orientation is an orientation that is likely to be taken when a user holds the communication terminal 20 in his / her hand. The vertical orientation is particularly likely to be taken in a communication terminal 20 used by a user other than an athlete during a competition. The vertical orientation is an example of a first orientation in which the long side of the display area of ​​the UI unit 24 is vertical. The horizontal orientation is an example of a second orientation in which the short side of the display area of ​​the UI unit 24 is vertical. The horizontal orientation is an orientation that is likely to be taken when a user places the communication terminal 20 in a predetermined place, and is particularly likely to be taken in a communication terminal 20 used by an athlete during a competition.

[0067] The imaging unit 27 acquires imaging information. The imaging unit 27 includes an imaging lens and an imaging element such as a CMOS or a CCD, captures an image, and generates imaging information indicating the captured image. The imaging information may include a still image, but it is more preferable that the imaging information includes a moving image.

[0068] The communication terminal 20 configured as described above has a function of performing wireless communication with the measuring device 10 by executing the application 251, and displaying the results of measurement by the measuring device 10 based on the measurement data received from the measuring device 10. The communication terminal 20 is particularly characterized by a function of receiving measurement data without setting up pairing with the measuring device 10, and a function of performing display based on the received measurement data. These features will be described in detail in the following sections [4. Operation of the system 1] and [5. Display processing].

[0069] [4. System 1 Operation] <4-1 Communication connection procedure> Fig. 9 is a sequence diagram showing the procedure for establishing a communication connection between the measurement device 10 and the communication terminal 20 in the system 1. The process of Fig. 9 is executed as a pre-setting for the communication terminal 20 to receive measurement data without setting up pairing with the measurement device 10. This process enables anyone to perform wireless communication between the communication terminal 20 and the measurement device 10 without pairing. In the following, the communication terminal 20 functions as a central in BLE-based wireless communication (hereinafter sometimes referred to as "BLE communication"), and the measurement device 10 functions as a peripheral in the BLE communication.

[0070] The measurement device 10 functioning as a peripheral waits for a connection from the communication terminal 20. In the measurement device 10, the control unit 13 detects the surrounding communication terminal 20 by performing broadcast communication, which is called advertising in BLE communication, using the communication unit 16. The control unit 13 transmits data to an unspecified number of parties by performing broadcast communication (step S11). This data is referred to as an "advertisement packet" below. The control unit 13 periodically transmits the advertisement packet (also referred to as transmitting an advertisement) while waiting for a connection. The advertisement transmission period is set in advance and may be, for example, every 100 milliseconds or every second. The advertisement packet may include the name and attribute data of the measurement device 10. The above-mentioned identification number of the measurement device 10 may be used as the name of the measurement device 10. The control unit 13 may start advertising when the power of the measurement device 10 is turned on, or may start advertising in response to a user's instruction, exemplified by an operation of the operation unit 17 (for example, a measurement start button).

[0071] In each of the communication terminals 20 functioning as a central, the control unit 21 performs a process of receiving an advertising packet by scanning using the communication unit 23. As a result, the communication terminal 20 identifies what peripheral devices are present in the vicinity. In the communication terminal 20, the control unit 21 transmits a connection request to the measurement device 10 identified by receiving the advertising packet (steps S12, S13, S14, and S15). If this connection request is transmitted without an explicit instruction from the user, the burden on the user may be reduced. In addition, when the control unit 21 receives advertising packets from multiple measurement devices 10, in this embodiment, the measurement devices 10A and 10B, it is preferable that the control unit 21 transmits a connection request to each of the measurement devices 10. In this embodiment, since the communication terminals 20A to 20D exist within the location area T1, each of the communication terminals 20A to 20D transmits a connection request to the measurement device 10 that is the transmission source of the advertising packet. Since the communication terminals 20E and 20F do not receive the advertising packet, they do not transmit a connection request to such a measurement device 10.

[0072] When the control unit 13 in the measurement device 10 receives a connection request from each communication terminal 20 using the communication unit 16, the control unit 13 establishes a connection with the communication terminal 20 that is the source of the connection request by BLE communication (step S16). In this manner, the control unit 13 detects the communication terminal 20 that is to make a connection request. In this embodiment, since four communication terminals 20A, 20B, 20C, and 20D are present in the location area T1, the process of steps S11 to S15 realizes a communication connection between the measurement device 10 and each of the communication terminals 20A, 20B, 20C, and 20D by BLE communication. This BLE communication allows measurement data to be transmitted from the measurement device 10 to the communication terminal 20. In this embodiment, the communication terminals 20A, 20B, 20C, and 20D are communication terminals used by related parties, but if communication terminals 20E and 20F used by a third party are present in the location area T1, the communication terminals 20E and 20F are also connected to the measurement device 10 by communication. In this way, any communication terminal 20 that is capable of BLE communication with the measurement device 10 and has the application 251 installed can communicate with the measurement device 10. This means that anyone can connect their own communication terminal 20 to the measurement device 10 as long as it is within the range of the number of communication terminals 20 that the measurement device 10 can communicate with at the same time.

[0073] When a connection is established with the measuring device 10 by BLE communication in the communication terminal 20, the control unit 21 displays, for example, a menu screen shown in FIG. 10 based on the application 251. In FIG. 10, "BSG BLE_802D57" displayed under the character string "Measuring Device" is the identification number of the measuring device 10A, and "BSG BLE_900FAF" is the identification number of the measuring device 10B. The identification number "BSG BLE_900FAF" displayed to the right of the character string "Measuring Device" means that the measurement result of the measuring device 10B is currently being displayed. In this way, it is possible to perform simultaneous measurement of multiple devices and display the measurement results. The display of the measurement results will be described later.

[0074] <4-2 Operation during measurement> FIG. 11 is a sequence diagram showing the operation of the system 1 during measurement. In the measurement device 10, the control unit 13 measures the speed and the like of the object based on the result of measurement by the microwave Doppler sensor 11 (step S21). The measurement method and measurement contents for each mode are as described above.

[0075] When the control unit 13 performs a measurement, it transmits measurement data indicating the result of the measurement to the communication terminal 20 connected by BLE communication using the communication unit 16 (steps S22, S23, S24, S25). Here, the control unit 13 transmits the measurement data to each of the communication terminals 20A, 20B, 20C, and 20D. The control unit 13 may transmit the measurement data to the communication terminal 20 immediately after the measurement, and in particular may transmit the measurement data in real time. The control unit 13 may transmit the measurement data for a predetermined time after the measurement, and in particular may transmit the measurement data for several seconds (for example, several seconds after the speed measurement). In particular, the control unit 13 may transmit the measurement data for a predetermined period after the measurement, and when the next measurement is performed, may transmit the measurement data corresponding to the next measurement for a predetermined period. In this way, the control unit 13 may transmit the measurement data based on the result of the latest measurement. In this way, the user of the communication terminal 20 can easily intuitively understand, while watching the competition of the athletes, what action is the measurement result based on when being displayed on the communication terminal 20.

[0076] When the control unit 21 in the communication terminal 20 receives the measurement data, the control unit 21 performs a display process to display based on the received measurement data using the UI unit 24 (steps S26, S27, S28, S29). In the communication terminal 20, the control unit 21 may display the measurement result using the UI unit 24 based on the measurement result of step S21. In this way, the user can understand the measurement result by looking at the UI unit 24 of the measurement device 10.

[0077] [5. Display processing] The display process in steps S26 to S29 will be described below.

[0078] <5-1. Displaying the measurement result screen> The control unit 13 may display a display based on the most recently received measurement data in preference to older measurement data on the measurement result display screen. For example, when the control unit 13 receives new measurement data, the control unit 13 may switch the measurement result display screen currently being displayed to a display based on the new measurement data, instead of the measurement result previously displayed. When the control unit 13 receives an operation to select the menu "Received data" on the menu screen of Fig. 10, the control unit 13 may cause the UI unit 24 to display a measurement result display screen. The control unit 13 may display the measurement result display screen so that the measurement results are displayed separately for each measurement device 10 (measurement instrument).

[0079] 12 and 13 are diagrams showing a measurement result display screen in pitching mode. As shown in FIG. 12 and FIG. 13, the measurement result display screen in pitching mode is a screen that displays each measurement result of "initial speed", "final speed", "section" (distance between initial speed and final speed), and "estimated speed at home base" under the character string "pitching" in addition to the identification number of the measuring device 10, measurement No., and measurement date. Here, the identification number of the measuring device 10, "BSG BLE_802D57", of the measuring device 10A that performs the measurement on the ball 30A, is displayed. As the measurement No., "No. 200" is assigned in the example of FIG. 12, and "No. 222" is assigned in the example of FIG. 13, and a different number is assigned for each measurement opportunity. Basically, the measurement No. should be assigned so that the measurement No. increases by one each time the number of measurements increases by one. The measurement date indicates the time when the measurement was performed.

[0080] As measurement results, "initial velocity," "final velocity," and "section" are measurement results included in the measurement data. Here, the measurement result for "initial velocity" is displayed in a larger size than the measurement results for "final velocity" and "section." This is based on the knowledge that when pitching ball 30A, knowing the initial velocity is the most important thing. For example, the ball speed often displayed in baseball broadcasts is often the initial velocity, and it is recognized as an important measurement result in knowing the pitching motion.

[0081] The "estimated speed of arrival at home base" corresponds to "home" described in FIG. 2, and is synonymous with the predicted speed of arrival of the ball 30A at home base. This allows the user to grasp how far the ball is moving at the position of home base, and to grasp the speed of the ball in more detail than before. The control unit 21 calculates the estimated speed of arrival at home base by a predetermined algorithm based on the measurement data. The control unit 21 may calculate the estimated speed of arrival at home base based on a predetermined function with the initial speed, final speed, and interval as variables, or may calculate the estimated speed of arrival at home base based on a table that stores the estimated speed of arrival at home base in association with the initial speed, final speed, and interval. For example, if the distance between the initial speed and final speed is a standard distance (18.44 m in baseball) between the pitcher and the catcher (pitching distance) in baseball or softball, for example, the final speed may be the estimated speed of arrival at home base. If the distance between the initial speed and final speed is shorter than this standard pitching distance, the estimated speed of arrival at home base will be slower than the final speed, and if the interval is longer than this standard pitching distance, the estimated speed of arrival at home base will be slower than the speed. The control unit 21 may not display the estimated speed of arrival at home base when the distance between the initial speed and the final speed is outside a predetermined distance range according to a standard pitch distance. For example, the control unit 21 may display the result of the estimated speed of arrival at home base as "---km / h". In this way, when the ball moves outside the predetermined distance range, the possibility that the user will understand the erroneous content of the predicted speed of arrival at home base can be reduced. For example, when the moving distance of the ball 30A is extremely long or extremely short, the quality of the predicted speed of arrival at home base may also be reduced because it deviates from the distance assumed in baseball, so it is based on the knowledge that such a measurement result should not be given to the user. The "estimated speed of arrival at home base" may be displayed on the measurement device 10, but by displaying it only on the communication terminal 20 without displaying it on the measurement device 10, it is expected that the function of the application 251 will be improved and the use of the application 251 will be promoted.

[0082] FIG. 14 is a diagram showing a measurement result display screen in the batting mode. As shown in FIG. 14, the measurement result display screen in the batting mode is a screen in which the measurement results of "swing speed", "ball speed", and "distance" are displayed under the character string "batting" in addition to the identification number of the measuring device 10, the measurement number, and the measurement date. As the identification number of the measuring device 10, the identification number of the measuring device 10B that performs the measurement on the bat 30B may be displayed. As the measurement number, "No. 94" is assigned in the example of FIG. 14, and a different number is assigned for each measurement opportunity. Basically, the measurement number may be assigned so that the measurement number increases by one each time the number of measurements increases by one. The measurement date indicates the time when the measurement was performed.

[0083] The measurement results "swing speed," "ball speed," and "distance" are included in the measurement data. Here, the measurement result for "swing speed" is displayed in a larger size than the measurement results for "ball speed" and "distance." This is based on the knowledge that when swinging with bat 30B, it is most important to know the swing speed. This is because swing speed is recognized as an important measurement result for understanding the batting motion.

[0084] In this way, the athlete or user involved can grasp the measurement results not only by looking at the display unit 14 of the measuring device 10 but also by looking at the UI unit 24 of the communication terminal 20, which can display a wider variety of information. For example, since the measuring device 10 is installed so that the measurement of the object can be performed, the display unit 14 may be difficult for a user such as an athlete to see, but the measurement results can be grasped from the UI unit 24 of the communication terminal 20, which is easier to see. Furthermore, the display unit (UI unit 24) of the communication terminal 20, such as a smartphone or tablet computer, is often configured to display information in a wider variety of expressions than the display unit 14 of the measuring device 10, so that the measurement results can be displayed with higher quality. The higher quality may refer to improving the quality of the content of the displayed information, such as increasing the number of items of information displayed, or to improving the quality of visibility, such as increasing the number of colors displayed.

[0085] <5-2. Display mode switching> In the system 1, when the measurement device 10 is switched to either the pitching mode or the batting mode, the communication terminal 20 may switch the mode of the screen that displays based on the measurement data according to the switched mode. In this way, when the measurement device 10 has a function of switching the mode according to the object of measurement, the display mode of the communication terminal 20 can be switched without an explicit instruction from the user, so that the operation to be performed by the user can be reduced and the user's convenience can be improved. When the mode is set by the method shown in FIG. 4 or the like in the measurement device 10, the control unit 13 transmits mode data indicating the set mode to the communication terminal 20 using the communication unit 16. When the control unit 21 in the communication terminal 20 receives the mode data using the communication unit 23, it may switch the display to a screen (the screen of FIG. 12 or 13 or the screen of FIG. 14) with a layout according to the mode of the setting screen based on the received mode data.

[0086] <5-3. Switching the display of the measurement results screen> In the communication terminal 20, the control unit 21 may have a function of switching the display of the measurement result screen in the UI unit 24. In this way, the user can change the display based on the measurement data in the UI unit 24 according to preference. For example, the following may be done.

[0087] <5-3-1. Display switching according to the orientation of the communication terminal 20> In the communication terminal 20, the control unit 21 may have a function of switching the display of the UI unit 24 according to the attitude of the communication terminal 20. In this way, the user can view the display based on the measurement data in the UI unit 24 in a manner suitable for the attitude of the communication terminal 20. The attitude of the communication terminal 20 includes a portrait orientation (an example of a first attitude) in which the long side of the display area of ​​the UI unit 24 is vertical, and a landscape orientation (an example of a second attitude) in which the short side of the display area of ​​the UI unit 24 is vertical. The control unit 21 may determine whether the orientation is portrait or landscape based on the attitude of the communication terminal 20 measured by the attitude sensor 26.

[0088] When the communication terminal 20 is in the vertical position, the control unit 21 may display the measurement result display screen described in Figs. 12 to 14. This measurement result display screen is a screen that displays information based on the measurement data in each of a plurality of regions obtained by dividing the display area vertically in each of the pitching mode and batting mode. The vertical position is a posture that is likely to be taken by a user when holding the communication terminal 20 in his / her hand, and allows the user to simultaneously view and understand the contents of a plurality of items of information. The vertical position is a posture that performs so-called vertical screen display, and is based on the knowledge that this is particularly likely to be taken by a communication terminal used by a user other than an athlete during a competition. In this way, when the communication terminal is in the vertical position, it can be said that the control unit 21 displays detailed information based on the measurement data.

[0089] When the communication terminal 20 is placed horizontally, the control unit 21 may display the measurement result display screen described in FIG. 15. When placed horizontally, the control unit 21 displays the measurement values ​​(measurement results) for a specific item in a landscape format. In this embodiment, when the communication terminal 20 is placed horizontally, the control unit 21 displays the display based on the measurement data displayed in one of the multiple areas, which is also displayed when the communication terminal 20 is placed vertically, in an enlarged manner compared to when the communication terminal 20 is placed vertically. In the pitching mode, the control unit 21 may display the "initial speed" in an enlarged manner. The control unit 21 may hide the "final speed", "section", and "estimated speed at home base arrival", which is desirable for making the "initial speed" easier to view, but some of them may be displayed in a reduced size, etc. In the batting mode, the control unit 21 may display the "swing speed" in an enlarged manner. The control unit 21 may hide the "ball speed" and "flying distance", which is desirable for making the "swing speed" easier to view, but some of them may be displayed in a reduced size, etc.

[0090] The horizontal orientation is a posture that is likely to be adopted when a user such as an athlete places the communication terminal 20 (in this embodiment, the communication terminal 20D) in a predetermined location, and although the distance from the user may be relatively large, the contents of the information can be easily understood by the enlarged display. The horizontal orientation is a posture for so-called horizontal screen display. It is based on the knowledge that this is particularly likely to be adopted for the communication terminal 20 used by athletes during a competition. For example, the display is suitable for the athlete P11 practicing while checking the ball speed for each pitch, or the athlete P13 practicing while checking the swing for each swing. In this manner, when the display is horizontal, the control unit 21 can display information for the athletes competing based on the measurement data.

[0091] <5-3―2. Display switching according to explicit user instructions> Instead of switching between the display of the measurement result screen described in FIG. 11 to FIG. 13 and the display of the measurement result screen described in FIG. 14 according to the attitude of the communication terminal 20 without an explicit instruction from the user, the control unit 21 of the communication terminal 20 may switch this display in response to an explicit instruction from the user. For example, when the control unit 21 is displaying the measurement result screen described in FIG. 11 to FIG. 13, if a predetermined operation (e.g., tap) is received on the UI 24, the control unit 21 may switch to the display of the measurement result screen described in FIG. 14 (for example, a screen enlarged in landscape). Also, when the control unit 21 is displaying the measurement result screen described in FIG. 14 (for example, a screen enlarged in landscape) if a predetermined operation (e.g., tap) is received on the UI 24, the control unit 21 may switch to the display of the measurement result screen described in FIG. 11 to FIG. 13.

[0092] <5-4. Displaying the history of the communication terminal 20> In the communication terminal 20, the control unit 21 may have a function of storing measurement data in the memory unit 25 and displaying a measurement history based on the results of past measurements. When the control unit 13 receives an operation to select the "History display" menu on the menu screen of Fig. 10, it may cause the UI unit 24 to display a history display screen. The control unit 13 may cause the history display screen to display the history of measurement results separated by results for each measurement device 10 (measurement instrument).

[0093] FIG. 16 is a diagram showing a history display screen related to the pitching mode. FIG. 17 is a diagram showing a history display screen related to the batting mode. In the history display screens of the pitching mode and the batting mode, the screen area is vertically divided into a plurality of areas (seven in this case), and the control unit 21 displays the history of the measurement results in each area. The contents of the history in each area are the same as the contents included in the measurement result screen described in FIGS. 12 to 14. The control unit 21 displays the history so that the newer the measurement, the higher it is located, but the reverse may be possible, and the control unit 21 may have a sorting function for rearranging the history in ascending or descending order for the measurement result items specified by the user.

[0094] <5-5. Display of associated imaging information and measurement results of communication terminal 20> The control unit 21 of the communication terminal 20 may have a function of acquiring imaging information from the imaging unit 27 while the competition is being held, and a function of recording the imaging information in the storage unit 25 in association with the measurement data. The users U21-U23 aim the imaging unit 27 of the communication terminal 20 in the direction of the athletes P11-P13 and capture images. The control unit 21 may associate the imaging information acquired from the imaging unit 27 at that time with the measurement data received from the measuring device 10 and store them in the storage unit 25. The control unit 21 may record the imaging information so that a different imaging information file (e.g., a video file) is generated for each measurement opportunity according to the timing of acquisition of the measurement data.

[0095] Furthermore, the control unit 21 may use the UI unit 24 to simultaneously perform displays based on the recorded measurement data and the imaging information. In this way, the user can simultaneously view the imaging information showing the contents captured by the imaging unit 27 while the competition is being held and the results measured during the competition. Since the user can associate the state of the object and its surroundings while the competition is being held with the results of the measurement, this display can be useful, for example, for checking the form of the athlete and considering measures to improve it. The associated display may be performed either during the competition or after the competition is over.

[0096] 18 is a diagram showing an association display screen in the communication terminal 20. The control unit 21 may display an area T11 for displaying recorded imaging information in a part of the screen area of ​​the UI unit 24, and may display an area T12 for displaying measurement results based on measurement data stored in the storage unit 25 near the area T11. The control unit 21 may perform such association display for each measurement occasion. When the control unit 13 receives an operation to switch the measurement occasion, it may perform association display for another measurement occasion. Note that the control unit 21 may perform association display for two or more measurement occasions on the same screen.

[0097] According to the system 1 described above, it is possible to provide a technology for enhancing the convenience when sharing the measurement results regarding a predetermined object used in a predetermined competition performed by the measuring device 10 with the users of the communication terminals 20 existing around the measuring device 10. In a competition exemplified by baseball, there are often a plurality of people such as the family, coach, team mates, etc. of the athlete near the athlete, and as a result, there are often a plurality (for example, a large number) of communication terminals 20 used by each person. In such a case, since the measurement data is transmitted from the measuring device 10 to each person's communication terminal 20, it is possible to easily realize the sharing of the measurement results among the plurality of people near the athlete. Also, since the measurement results regarding the object by the measuring device 10 are considered to rarely include highly confidential information, when sharing with the users of the communication terminals 20, the merit of giving priority to ensuring the convenience of the users rather than viewpoints such as privacy is great. For example, even if anyone can communicatively connect their own communication terminal 20 to the measuring device 10 and view the display based on the measurement data from the measuring device 10, it is based on the idea that the demerits outweigh the merits.

[0098] [Explanation of matters related to 6.SDGs] By introducing the system 1, it can be expected to contribute to some items of the Sustainable Development Goals (SDGs) as follows.

[0099] <SDG3: Good health and well-being for all> Measurements in sports competitions are useful for monitoring the fitness and performance of athletes. According to the system 1, it is possible to improve an individual's health and well-being through appropriate training and the pursuit of performance.

[0100] <SDG4: Quality education for all> By using the system 1, it can be expected that the training and performance evaluation of sports will be improved. As a result, high-quality education and training can be provided for sports athletes and coaches, and skill improvement becomes possible.
