DETAILED DESCRIPTION OF THE INVENTION

[0009] Embodiment 1 ***Outline of the terminal device control system*** FIG. 1 is a schematic diagram of a control system for a terminal device according to this embodiment. The control system 100 of the terminal device 20 of this embodiment is configured to include, for example, a terminal device 20 worn by a triathlon athlete and a server 30 connected via an LPWA (Low Power Wide Area) network 45, and is a competition assistance system in which the terminal device 20 records the athlete's competition record and the server 30 keeps track of the athlete's location, etc.

[0010] The control system 100 is composed of a terminal device 20, a server 30, a secretariat computer 40, a smartphone 50, and the like. The terminal device 20 is worn by the athlete, and in a preferred example, as shown in FIG. 1, it is a plate-shaped device several centimeters square that is attached to the athlete's upper arm with a band. Note that the attachment location is not limited to the upper arm, and it may be attached to the athlete's body. The terminal device 20 stores race course information in advance and automatically starts up as the race time approaches. The terminal device 20 is worn by all athletes. The terminal device 20 is equipped with a position detection unit 2 (FIG. 2) that receives satellite signals transmitted from GPS (Global Positioning System) satellites 52 and an LPWA-compatible communication unit 3 (FIG. 2), detects the current location of the terminal device 20, and transmits the detected location information to the server 30 via the LPWA network 45. Note that the LPWA network 45 is connected to a network NW, which is an Internet environment.

[0011] The server 30 is the core server of the control system 100 and includes a control unit 31, a memory unit 32, and a communication unit 33. The control unit 31 includes one or more processors. The memory unit 32 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and stores programs executed by the control unit 31 and related data. The programs include a competition monitoring program that manages the location of the terminal device 20. The related data includes course information. The communication unit 33 is a wired LAN (Local Area Network) port and is connected to the network NW via a LAN cable. Any configuration that can be connected to the network NW will do, and for example, a wireless communication module that complies with wireless LAN standards may be used.

[0012] The secretariat computer 40 is a computer used by the competition secretariat, and has the same configuration as the server 30. The secretariat computer 40 creates information such as course information for the competition and ID correspondence information that associates the IDs (identifications) of the competitors with the terminal devices 20, and transmits this information to the server 30 via the network NW. The smartphone 50 is a smartphone carried by an athlete, and has a dedicated application installed for obtaining information on competition results. By executing the application, the smartphone 50 can access the server 30 after the competition is over and check the athlete's own competition record, the results of the competition, and the like.

[0013] ***Outline of terminal device*** FIG. 2 is a functional block diagram showing a schematic configuration of the terminal device. Next, the configuration of the terminal device 20 will be described.

[0014] The terminal device 20 is composed of a control unit 1, a position detection unit 2, a communication unit 3, a timing unit 5, a memory unit 6, a motion detection unit 7, a sensor unit 8, and a power supply circuit 9. In a preferred example, the terminal device 20 is not provided with a display unit or operation buttons. The control unit 1 includes a processor, and operates in accordance with a program stored in the storage unit 6 to comprehensively control the operation of the terminal device 20.

[0015] The position detection unit 2 is a GPS receiving module that receives radio waves from multiple GPS satellites 52 (FIG. 1), measures the position using the radio waves, and outputs position information based on the positioning results. The GPS satellites 52 correspond to positioning information satellites. The communication unit 3 is a communication module that complies with LPWA. For example, Sigfox (registered trademark) or LTE Cat.M1 is used as LPWA. Note that the communication unit 3 is not limited to these standards, and any LPWA network may be used, such as LoRa (registered trademark), Wi-Fi (registered trademark), HaLow (registered trademark), Wi-SUN (registered trademark), RPMA (registered trademark), Flexnet (registered trademark), or NB-IoT.

[0016] The timekeeping unit 5 is a real-time clock equipped with a quartz crystal oscillator X1, and continues to measure time even when the control unit 1 is turned off, supplying time data to the control unit 1. In other words, the timekeeping unit 5 measures time information and operates even in the sleep mode described below. The storage unit 6 includes a ROM and a RAM, and stores programs executed by the control unit 1, related data, etc. The programs include an operation mode switching program (described later), etc. The related data includes course information.

[0017] In a preferred embodiment, the motion detection unit 7 is equipped with an acceleration sensor and a gyro sensor. In a preferred embodiment, the acceleration sensor uses a three-axis acceleration sensor, that is, an X-axis, a Y-axis, and a Z-axis. The acceleration sensor detects acceleration accompanying the movement of the terminal device 20 and outputs a detection signal to the control unit 1. The gyro sensor is an angular velocity sensor, and in a preferred embodiment, a gyro sensor that detects rotation in three dimensions is used. In other words, the motion detection unit 7 uses the acceleration sensor and gyro sensor to detect the movement of the terminal device 20 worn by the athlete.

[0018] In a preferred example, the sensor unit 8 is equipped with a temperature sensor and a pressure sensor, which detects the temperature and altitude around the terminal device 20 and outputs a detection signal to the control unit 1. However, the sensor unit 8 is not limited to these sensors, and any sensor capable of detecting environmental information around the terminal device 20 may be used, and for example, an optical sensor may also be provided. The power supply circuit 9 is a power supply circuit powered by a battery Bt, and supplies operating voltage to each component of the terminal device 20. The battery Bt is, for example, a secondary battery such as a lithium ion battery, and is fully charged before the race.

[0019] ***How ​​to switch operation modes during competition*** Fig. 3 is a flow chart showing the flow of the operation mode switching process in the terminal system, and Fig. 4 is a table showing the timing state, measurement state, and measurement content in each operation mode. Here, the flow of the process of switching the operation mode of the terminal device 20 in the control system 100 will be described mainly with reference to FIG. 3, and also with reference to FIGS. 1, 2, and 4 as appropriate.

[0020] First, course information is stored in the memory unit 32 of the server 30. The course information is supplied from the administrative office computer 40. More specifically, in step S50, the course information, ID correspondence information, etc. transmitted from the secretariat computer 40 are received by the communication unit 33 of the server 30 via the network NW and stored in the memory unit 32. In step S51, the course information of the server 30 is transmitted to the terminal device 20. In addition, in the server 30, when the race start time according to the course information arrives, the watching program of the terminal device 20 is started.

[0021] Next, the operation of the terminal device 20 will be described. In step S10, the course information is received and stored in the memory unit 6 of the terminal device 20. In a preferred example, the course information is written to all terminal devices 20 by the competition office as part of the preparations for the competition. Writing may be performed using a dedicated writing device such as a cradle, or may be written to the memory unit 6 via the communication unit 3 of the terminal device 20 using LPWA. The course information includes the start time of the race, start position information, goal position information, race type, race information that defines the order, transition information, etc. Details of each piece of information will be described later.

[0022] In step S11, the terminal device 20 enters the sleep mode in Table 28 of FIG. 4. More specifically, the terminal device 20 into which the course information has been written is set to enter the sleep mode. The sleep mode is a state in which only the timing unit 5 is operating. In other words, the sleep mode is an energy-saving mode in which the operation of at least the position detection unit 2 and the motion detection unit 7 is stopped. The course information will be described using the course information of a triathlon competition as an example.

[0023] ***Standby Mode*** In step S12, when the timing unit 5 indicates that it is 10 minutes before the start of the race, the terminal device 20 starts up and transitions to standby mode in Table 28. More specifically, an operation mode switching program is resident in the terminal device 20, and 10 minutes before the start time of the race in the course information, the terminal device 20 starts up and enters standby mode. In standby mode, each unit of the terminal device 20, including the position detection unit 2, starts up, but the accumulated time and accumulated distance are not recorded. In other words, in standby mode, the position detection unit 2 and motion detection unit 7 start up and wait for the start of the race. The reason for starting up 10 minutes before the race is to ensure that there is enough time to reliably perform position detection by the position detection unit 2. Therefore, the time is not limited to 10 minutes, and any time that allows for reliable position detection may be used. In step S13, when the start time of the competition has elapsed as measured by the timing unit 5 and a start determination has been made, the process shifts to the first measurement mode, which will be explained in detail below.

[0024] ***Start Judgment*** FIG. 5 is a plan view of the area near the starting point. First, the start position information of the course information includes latitude / longitude position data for two end points of the start line 22 and latitude / longitude position data for two end points of a backup line 24 that is a predetermined distance away from the start line 22. The backup line 24 is a virtual line set on the course a predetermined distance beyond the start line as a backup in case the passing of the start line 22 cannot be detected due to a GPS measurement error, so that measurement can be started even if the passing of the start line cannot be detected.

[0025] Specifically, the start position information includes latitude / longitude position data of one end 21a and the other end 21b of the start line 22 in FIG. 5, and a virtual line connecting the one end 21a and the other end 21b is set inside the terminal device 20 as the start line 22. The start position information also includes latitude / longitude position data of one end 23a and the other end 23b of a backup line 24 that is a predetermined distance away from the start line 22. The virtual line connecting the one end 23a and the other end 23b is set inside the terminal device 20 as the backup line 24. Note that the position data of the backup line 24 may be distance information from the start line 22. The predetermined distance is, for example, 30 m. Note that this is not limited to this and may be set appropriately depending on the course settings and the content of the competition.

[0026] FIG. 6 is a flowchart showing the flow of the start determination process. Next, the specific start determination process will be described mainly with reference to FIG. 6 and also with reference to FIG. In step S60, the position detection unit 2 detects the current position. In step S61, it is determined whether the start time of the competition has passed based on the timing of the timing unit 5. If the start time has passed, the process proceeds to step S62. If the start time has not passed, the process returns to step S60, and the current position is successively detected. In step S62, the position detection unit 2 detects the current position.

[0027] In step S63, it is determined whether the start line 22 has been passed by moving from the position detected in step S60 to the position detected in step S62. More specifically, it is determined whether the start line 22 has been passed by moving from the position detected just before the start time of the race to the position detected after the start time has elapsed. If the start line 22 has been passed, the process proceeds to step S64. If the start line 22 has not been passed, the process proceeds to step S65. In step S64, the operation mode is switched to the first measurement mode. More specifically, since the start time of the competition has passed and the start has been determined, the operation mode is switched to the first measurement mode and measurement begins. As shown in FIG. 4, the first measurement mode is a measurement mode corresponding to the first competition event, swimming. In other words, the control unit 1 controls the operation of the terminal device 20 based on the course information, the current time, and the current position information detected by the position detection unit 2. In other words, the operation mode of the terminal device 20 is switched.

[0028] In step S65, it is determined whether the backup line 24 has been passed by movement from the position detected in step S60 to the position detected in step S62. More specifically, it is determined whether the backup line 24 has been passed by movement from the position detected just before the start time of the race to the position detected after the start time has elapsed. If the backup line 24 has been passed, proceed to step S64. If the backup line 24 has not been passed, return to step S62 and wait for passage of the start line 22 or the backup line 24.

[0029] In other words, the start position information includes a virtual start line that coincides with the actual start line 22 and a backup line 24 that is a predetermined distance away from the virtual start line, and when the control unit 1 detects, based on the position information detected by the position detection unit 2, that the position of the terminal device 20 has passed the start line 22 or the backup line 24, it determines that the competition has started and switches to the first measurement mode.

[0030] ***Swim Measurements*** Return to Figure 4. As shown in the first measurement mode in Table 28, in the first athletic event, swimming, pace measurement and stroke pitch measurement are performed. Pace measurement is the average speed during swimming, and is measured based on positioning data detected by the position detection unit 2. Speed, distance, and trajectory can also be measured based on the positioning data. Stroke pitch measurement is performed by the motion detection unit 7. This is because the terminal device 20 is worn on the athlete's upper arm, and therefore the periodic arm movement caused by swimming can be detected. The data obtained from the pace measurement and stroke pitch measurement can be used as diagnostic data for improving records. In this way, the terminal device 20 measures items that are useful for exercise diagnosis for each sport.

[0031] ***Transition Mode-1*** Return to Figure 3. After the first swim, you enter the transition area. In step S14, when it is determined that the transition mode should be started based on the position detection by the position detection unit 2 and the movement detection by the motion detection unit 7, the transition mode is switched to. The transition mode is an operation mode used in the transition area where the type of sport is switched. This will be explained in detail below.

[0032] FIG. 7 is a diagram showing the vicinity of the transition area. First, the setting of a zone in the vicinity of the transition area 55 for determining the start / end of the transition mode will be described with reference to FIG. 7 is an area where athletes can change into different events, such as taking off their wetsuits and putting on shoes when switching from swimming to biking, or picking up their bikes for biking. A similar transition area is also provided when switching from biking to running.

[0033] 7, the transition area 55 is a rectangular area that follows the course, with the left short side of the rectangle being the start line 55a and the right short side being the finish line 55b. The course information includes latitude / longitude position data for the four vertices of the rectangle, and the terminal device 20 recognizes the rectangular area connecting the four vertices as the transition area 55.

[0034] As shown in FIG. 7, the course information includes a first zone 56, a second zone 57, and a third zone 58 for determining the start / end of the transition mode. The first zone 56 is a circular area with a radius r1 centered at point 56c near the start line 55a, and covers the start line 55a. The second zone 57 is a circular area with a radius r2 centered at point 57c, which is approximately the center of the rectangular transition area 55, and covers more than half of the transition area 55. The third zone 58 is a circular area with a radius r3 centered at point 58c near the finish line 55b, and covers the finish line 55b. The radius r1 of the first zone 56 and the radius r3 of the third zone 58 are approximately the same, and the radius r2 of the second zone 57 is set larger than the radius r1. In other words, the first zone 56, the second zone 57, and the third zone 58 are set to cover approximately the area through which athletes pass near the transition area 55.

[0035] The first zone 56 and the second zone 57 overlap slightly. Similarly, the second zone 57 and the third zone 58 overlap slightly. Most of the transition area 55 is covered by the three consecutive zones, the first zone 56, the second zone 57, and the third zone 58. However, the zone arrangement is not limited to this, and it is sufficient that three zones are provided, and it may be changed as appropriate depending on the course setting.

[0036] FIG. 8 is a flowchart of the transition mode start process. First, the transition mode start determination process will be described mainly with reference to FIG. 8, and also with reference to FIGS. 4 and 7 as appropriate.

[0037] In step S70, the position detection unit 2 detects the current position. In step S71, the motion detection unit 7 detects the direction of movement from the position detected in step S70. In step S72, it is determined whether the current position detected in step S70 is within the first zone 56 in Fig. 7. If it is within the first zone 56, the process proceeds to step S73. If it is not within the first zone 56, the process returns to step S70.

[0038] In step S73, it is determined whether the movement direction detected in step S71 is approaching the second zone 57 in Fig. 7 or whether the current position detected in step S70 is within the second zone 57. If the movement direction is approaching the second zone 57 or the current position is within the second zone 57, the process proceeds to step S74. If the movement direction is not approaching the second zone 57 and the current position is not within the second zone 57, step S73 continues. In step S74, the process transitions to the transition mode of Table 28 in Fig. 4. In other words, since the terminal device 20 is approaching the second zone 57 from within the first zone 56 and is detected to be within the transition area 55, it is determined that the transition mode should be started, and the process switches to the transition mode.

[0039] FIG. 9 is a flowchart of the transition mode end determination process. Next, the transition mode termination determination process will be described mainly with reference to FIG. 9, and also with reference to FIGS. 4 and 7 as appropriate.

[0040] In step S80, the position detector 2 detects the current position. In step S81, the motion detection unit 7 detects the direction of movement from the position detected in step S80. In step S82, it is determined whether the current position detected in step S80 is within the second zone 57 of Fig. 7. If it is within the second zone 57, the process proceeds to step S83. If it is not within the second zone 57, the process returns to step S80.

[0041] In step S83, it is determined whether the movement direction detected in step S81 is approaching the third zone 58 in Fig. 7, or whether the current position detected in step S80 is within the third zone 58. If the movement direction is approaching the third zone 58 or the current position is within the third zone 58, the process proceeds to step S84. If the movement direction is not approaching the third zone 58 and the current position is not within the third zone 58, the process continues with step S83.

[0042] In step S84, the operation mode is switched to the next operation mode. In other words, since it is detected that the terminal device 20 is approaching the third zone 58 from within the second zone 57 and is leaving the transition area 55 to enter the next sporting event, it is determined that the transition mode has ended, and the operation mode is switched to the next operation mode. Note that if the sporting event before entering the transition area 55 was swimming, the operation mode is switched to the second measurement mode corresponding to bike in Table 28 of FIG. 4. In other words, when the terminal device 20 enters the transition mode, the timing unit 5 continues measuring time information, but stops measuring the cumulative time that is used to record the competition. Then, when the transition mode ends, the terminal device 20 transitions to a measurement mode corresponding to the next competition type and resumes measuring the cumulative time. Note that the suspension of cumulative measurement may be performed in combination with time and distance; for example, the cumulative time measurement may be suspended while the cumulative distance measurement is continued, or the cumulative distance measurement may be suspended while the cumulative time measurement is continued. Alternatively, both the cumulative time and the cumulative distance may be suspended.

[0043] ***Measurements on a bike*** Return to Figure 3. In step S15, the bike race is measured in the second measurement mode. As shown in the second measurement mode in Table 28 of Fig. 4, in the second event, biking, only pace measurement is performed. The pace measurement is performed based on the positioning data detected by the position detection unit 2.

[0044] ***Transition Mode-2*** Return to Figure 3. In step S16, similar to the process in step S14, if it is determined that the transition mode should be started based on position detection by the position detection unit 2 and movement detection by the motion detection unit 7, the mode is switched to the transition mode. The method of determining the start / end of the transition mode is the same as that explained in Figs. 7 to 9. In a preferred example, if the event is switched from biking to running and it is determined that the transition mode should be ended, the mode is switched to the third measurement mode corresponding to the next event, running.

[0045] ***Run Measurements*** In step S17, the running race is measured in the third measurement mode. As shown in the third measurement mode in Table 28 of FIG. 4, in the third athletic event, running, pace, running pitch, and stride measurements are performed. Pace is measured based on positioning data detected by the position detection unit 2. Running pitch is measured by the motion detection unit 7. This is because the terminal device 20 is worn on the athlete's upper arm, making it possible to detect periodic body movements during running. Note that running pitch measurement also makes it possible to measure travel distance. Stride measurement uses stride information generated from distance information measured by the position detection unit 2 and running pitch information.

[0046] ***Goal Judgment -1*** In step S18, when a goal is determined based on the position detection by the position detection unit 2 and the movement detection by the motion detection unit 7, the recorded data is stored and transmitted. This will be explained in detail below.

[0047] FIG. 10 is a plan view of the area near the finish line. First, the goal position information of the course information includes latitude / longitude position data of one end 41a and the other end 41b of the goal line 42, and inside the terminal device 20, a virtual line connecting the one end 41a and the other end 41b is set as the goal line 42. The goal position information also includes goal requirement information. The goal requirement information includes a required number of goal crossings that specifies the number of times the goal line 42 must be crossed. Note that the goal requirement information can be changed as appropriate depending on the course settings.

[0048] FIG. 11 is a flowchart showing the flow of the goal determination process. Next, the specific start determination process will be described mainly with reference to FIG. 11 and also with reference to FIG. In step S90, the position detector 2 detects the current position. In step S91, it is determined whether the current position detected in step S90 has passed the goal line 42. Specifically, it is determined whether the goal line 42 has been passed by moving from the previously detected position in the sequential detection to the current current position. If the goal line 42 has been passed, the process proceeds to step S92. If the goal line 42 has not been passed, the process returns to step S90.

[0049] In step S92, it is determined whether the goal requirements are met. If the goal requirements are met, the process proceeds to step S93. If the goal requirements are not met, the process returns to step S90. For example, in the case of the goal setting in FIG. 10, the number of times the goal needs to be passed is set to one as the goal requirement information, so it is determined that one pass satisfies the goal requirements, and the process proceeds to step S93. In step S93, the measured recorded data is stored in the storage unit 6. In step S94, the recording data is transmitted by the communication unit 3. More specifically, the recording data is transmitted by the communication unit 3 to the server 30 via the LPWA network 45 (FIG. 1) and the network NW.

[0050] In other words, the goal position information includes a virtual goal line that coincides with the actual goal line 42 and a required number of times to cross the goal, which specifies the number of times to cross the virtual goal line, and the control unit 1 determines that a goal has been reached when the position of the terminal device 20 has passed the goal line 42 the same number of times as the required number of times to cross the goal, based on the position information detected by the position detection unit 2.

[0051] Return to Figure 3. In step S19, the terminal device 20 transitions to a sleep mode. More specifically, after the goal determination, the storage and transmission of the recorded data is completed, and therefore the terminal device 20 enters the sleep mode.

[0052] In step S52, the server 30 receives the recorded data from the plurality of terminal devices 20, collates it with the ID correspondence information, organizes it by rank, and stores it in the storage unit 32. In step S53, the server 30 makes the organized record data public. In detail, after the competition ends, the athletes can access the server 30 using a dedicated application on their smartphones 50 to check their own competition records, the results of the competition, and the like.

[0053] As described above, the terminal device 20, the control method for the terminal device 20, and the control system 100 for the terminal device according to this embodiment can provide the following effects. The terminal device 20 is a terminal device worn by the athlete and comprises a position detection unit 2 that detects the position based on satellite signals transmitted from positioning information satellites, a motion detection unit 7 that detects the movement of the terminal device 20, a timing unit 5 that measures time information, a memory unit 6 that stores course information including the start time of the competition, start position information, finish position information, type of competition, and competition information that defines the order, and a control unit 1 that controls the operation of the terminal device 20 overall, and the control unit 1 controls the operation of the terminal device 20 based on the course information, the current time, and the current position information detected by the position detection unit.

[0054] According to this, the terminal device 20 controls its operation based on the course information. For example, in the case of a triathlon competition, the terminal device 20 automatically switches the operation mode based on the course information, such as using a first measurement mode corresponding to swimming for swimming, a second measurement mode corresponding to cycling for biking, and a third measurement mode corresponding to running for running. Therefore, unlike conventional technology that required operational input into the terminal device each time a change in sport was made, terminal device 20 allows functions to be switched without requiring operational input by the athlete. Furthermore, conventional terminal devices that required input operations required advance instructions on how to use the terminal device before the start of the sport, but with terminal device 20, athletes only need to wear it, simplifying advance instructions and reducing the operational burden of the sporting event. Therefore, it is possible to provide a user-friendly terminal device 20 that can switch functions without requiring any operation input.

[0055] In addition, the terminal device 20 has multiple operating modes, including a sleep mode in which at least the position detection unit 2 and the motion detection unit 7 are stopped from operating, a standby mode in which the position detection unit 2 and the motion detection unit 7 are activated and the device waits for the start of the competition, multiple measurement modes in which the measurement content differs depending on the type of competition, and a transition mode used in the transition area where the type of competition changes, and the control unit 1 switches the operating mode of the terminal device 20 based on the course information, the current time, and the current position information detected by the position detection unit. According to this, the terminal device 20 automatically switches the operation mode of the terminal device 20 in accordance with the current time and the current position information detected by the position detection unit based on the course information. For example, in a triathlon competition, the operation mode is switched in the following order: sleep mode, standby mode, first measurement mode, transition mode, second measurement mode, transition mode, third measurement mode, and sleep mode. Therefore, it is possible to provide a user-friendly terminal device 20 that can switch functions without requiring any operation input.

[0056] The start position information also includes a virtual start line that coincides with the actual start line 22 and a backup line 24 that is a predetermined distance away from the start line 22, and when the control unit 1 determines, based on the position information detected by the position detection unit 2, that the position of the terminal device 20 has passed the start line 22 or the backup line 24, it switches to measurement mode.

[0057] This means that even if the passage of the start line 22 cannot be detected, such as when the satellite signal is weak and the error in the current location measured by the position detection unit 2 is large, the start can be determined by detecting the passage of the backup line 24. Therefore, the start determination can be performed reliably.

[0058] Furthermore, when the transition mode is entered, the control unit 1 continues timing the time information measured by the timing unit 5, but suspends the measurement of the cumulative time that is recorded for the competition. When the transition mode is ended, the control unit 1 transitions to the measurement mode corresponding to the next competition type, and resumes the measurement of the cumulative time.

[0059] This allows the time spent in the transition area to be excluded from the competition record, allowing for accurate competition records to be measured in accordance with the competition rules. Also, by stopping the measurement of cumulative time in transition mode, power consumption can be reduced.

[0060] The goal position information also includes a virtual goal line that coincides with the actual goal line 42 and a required number of times to pass the goal, which specifies the number of times to pass the goal line 42. The control unit 1 determines that a goal has been reached when the position of the terminal device 20 has passed the goal line 42 the same number of times as the required number of times to pass the goal, based on the position information detected by the position detection unit 2. This allows accurate goal determination based on goal information even with various course settings.

[0061] The control system 100 is a control system for a terminal device that includes a terminal device 20 worn by an athlete and a server 30 that is connectable to the terminal device via wireless communication. The terminal device 20 includes a position detection unit 2 that detects its position based on satellite signals transmitted from a positioning information satellite, a motion detection unit 7 that detects the movement of the terminal device 20, a timing unit 5 that measures time information, a memory unit 6 that stores course information including competition information that defines the start time of the competition, start position information, finish position information, the type of competition, and the order, a communication unit 3 that performs wireless communication, and a control unit 1 that overall controls the operation of the terminal device 20. The control unit 1 controls the operation of the terminal device 20 based on the course information, the current time, and the current position information detected by the position detection unit 2. This makes it possible to provide a control system 100 for the terminal device 20 that is easy to use and allows function switching without the need for operational input.

[0062] The control method for the terminal device 20 is a control method for the terminal device 20, which is equipped with a position detection unit 2 that detects its position based on a satellite signal transmitted from a positioning information satellite, a timing unit 5 that measures time information, and a memory unit 6 that stores course information including competition information that defines the start time of the competition, start position information, goal position information, type of competition, and order, and controls the operation of the terminal device 20 based on the course information, the current time, and the current position information detected by the position detection unit. This makes it possible to provide a method for controlling the terminal device 20 that is easy to use and allows function switching without requiring any operational input.

[0063] Embodiment 2 ***Goal Judgment -2*** FIG. 12 is a plan view of the vicinity of the goal point with a different setting, and corresponds to FIG. The finish line determination varies depending on the course setting. For example, in Fig. 12, the finish line is set to a track course 44 such as an athletics stadium, and an athlete entering from an external course must cross a finish line 47 once, run one lap around the rounded rectangular track course 44, and then cross the finish line 47 again to reach the finish line.

[0064] 12, the goal requirement information in the goal position information specifies that the required number of times to cross the goal is 2. The goal position information also includes latitude / longitude position data for one end 46a and the other end 46b of the goal line 47, and the imaginary line connecting the one end 46a and the other end 46b forms the goal line 47. Even with this course setting, goal determination is performed by the goal determination process of Fig. 11. More specifically, in determining whether the goal requirements are met in step S93, the number of times required to pass the goal is set to two as the goal requirement information, so two passes meet the goal requirements and it is determined that a goal has been reached. In other words, the control unit 1 determines that a goal has been reached when the position of the terminal device 20 has passed the goal line 47 the same number of times as the number of times required to pass the goal, based on the position information detected by the position detection unit 2.

[0065] ***Goal Judgment -3*** FIG. 13 is a plan view of the vicinity of the goal point with a different setting, and corresponds to FIGS. 13, the finish line 37 is set inside the indoor stadium 39. In this case, the satellite signals from the GPS satellites 52 are weak inside the indoor stadium 39, making it difficult for the position detection unit 2 to detect the position. For this reason, the finish information includes position information of the primary finish line 36 set outside the indoor stadium 39 and distance information D that defines the distance between the primary goal line 36 and the actual finish line 37.

[0066] More specifically, the goal position information includes latitude / longitude position data for one end 35a and the other end 35b of the primary goal line 36, and a virtual line connecting the one end 35a and the other end 35b is the primary goal line 36. The goal position information also includes distance information D between the primary goal line 36 and the actual goal line 37. The required number of times to cross the goal is set to one. Even with this course setting, goal determination is performed by the goal determination process of FIG. 11. More specifically, in determining whether the goal requirements are met in step S93, the number of times the goal must be crossed is set to one as the goal requirement information. In this case, the goal requirement is to move further in the distance information D after passing the primary goal line 36. The movement in the distance information D is detected by measuring the running pitch using the motion detection unit 7. In other words, when the terminal device 20 passes the primary goal line 36 and further movement in the distance information D is detected, the goal requirements are met and it is determined that a goal has been reached. In other words, it is determined that a goal has been reached when, based on the position information detected by the position detection unit 2, the position of the terminal device 20 passes the primary goal line 36, and then, based on movement detection by the motion detection unit 7, the position of the terminal device 20 reaches the distance specified in the distance information D.

[0067] As described above, according to the terminal device 20, the control method for the terminal device 20, and the control system 100 for the terminal device of this embodiment, the following effects can be obtained in addition to the effects of the first embodiment. The goal position information includes a virtual goal line that coincides with the actual goal line 47 and a required number of times to pass the goal, which specifies the number of times to pass the goal line 47. The control unit 1 determines that a goal has been reached when the position of the terminal device 20 has passed the goal line 47 the same number of times as the required number of times to pass the goal, based on the position information detected by the position detection unit 2. This allows accurate goal determination based on goal information even with various course settings.

[0068] The goal position information also includes a primary goal line 36 located before the actual goal line 37, and distance information D from the primary goal line 36 to the actual goal line 37. Based on the position information detected by the position detection unit 2, the control unit 1 determines that a goal has been reached when, after the position of the terminal device 20 passes the primary goal line 36, the motion detection unit 7 detects movement and the position of the terminal device 20 reaches the distance specified in the distance information D. This allows accurate goal determination based on goal information even with various course settings.

[0069] Although the above description has been given using a triathlon as an example, the present invention is not limited to this. For example, the events and order are not limited to swim, bike, and run. There may be two events, and the order may be changed. The present invention can also be applied to various other sports, such as duathlon, calfman, aquathlon, and Xterra. In these sports, even when the terminal device 20 and the control system 100 for the terminal device 20 are used, the same effects as those of the above embodiment can be obtained.
