  The present invention relates to an exercise support device, an exercise support system, an exercise support method, and an exercise support program.

  Conventionally, for example, as described in Patent Document 1, a device for notifying a player who plays sports such as soccer has been known. In Patent Document 1, position information of a plurality of players is detected, a player who can pass is determined based on the position information, and appropriate advice can be notified to a player who places a pass.

Japanese Patent No. 5504568

However, in patent document 1, there existed a possibility that the notification of advice might prevent a player's play. Specifically, since the advice is notified to the player while the play is in progress, the player may be distracted by the notified advice and may not be able to play originally. Thus, depending on the situation on the player side, there is a problem that the player's play is hindered by notifying the advice.
In Patent Document 1, it is difficult to say that advice can be reliably transmitted to the player. Specifically, the player may have missed the advice because he / she concentrates on the play while making a pass. Thus, depending on the situation on the player side, there is a problem that even if advice is provided, the advice may not be transmitted to the player.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the scale of each layer and each member is made different from the actual scale so that each layer and each member can be recognized.

(Embodiment 1)
(Outline of exercise support system)
FIG. 1 is an explanatory diagram showing an outline of an exercise support system. FIG. 2 is an explanatory diagram showing the appearance of the exercise support apparatus. In the present embodiment, an exercise support system for supporting exercise of tennis will be described as an example, but the present invention is an exercise support system for providing support related to various sports such as golf, baseball, and volleyball, The present invention can also be applied to an exercise support system that supports exercises other than sports such as rehabilitation exercises.

  The exercise support system 1 according to the present embodiment includes an exercise support device 3 attached to the body of a player PL who plays sports (tennis), and a sensor unit 10 (10A, 10B, 10C, 10D) and the like. In addition, the exercise support device 3 and the sensor unit 10 are connected to be able to communicate various data by communication 2 such as short-range wireless. However, the exercise support system 1 may have a configuration in which some of these configurations (elements) are omitted or a new configuration (element) is added.

  As shown in FIG. 1, the player PL holds the tennis racket RA and is ready to hit the ball BA. A sensor unit 10A is fixedly attached to the racket RA. A sensor unit 10C is built in the ball BA. Also, a spare racket RB that is not used for play and a bag BG containing sports equipment are placed beside the player PL. A sensor unit 10B is fixedly attached to the racket RB. A sensor unit 10D built in a clip-shaped fixture is attached to the bag BG with the hand-held portion of the bag BG interposed therebetween.

  The exercise support apparatus 3 shown in FIG. 2 is a wristwatch type apparatus that is worn on the wrist of the player PL, and includes a body movement detection unit 20 and a display unit 91. The body motion detection unit 20 detects the body motion information of the player PL. The display unit 91 is a display device capable of displaying images, characters, icons, and the like.

  The exercise support device 3 acquires the body motion information of the player PL by the body motion detection unit 20. The exercise support device 3 communicates with the sensor unit 10 and collects dynamic information from a plurality of tools. The control unit 40 (described later) of the exercise support apparatus 3 analyzes the movement information of the tool and the body movement information of the player PL, and determines whether or not the player PL can accept advice. If the player PL is in a state where it can accept advice, it is determined that it is an appropriate timing to notify the advice.

  The timing at which the player PL can easily accept the advice includes a state in which the player PL can switch consciousness and feeling during play. For example, while the player PL stops moving during a play and takes a short rest, it can be said that the player PL is switching consciousness and feeling for the next play. Such a time zone is an appropriate timing for notifying the advice. In addition, it can be said that the player PL can easily accept the advice because the play is not hindered even when the play is interrupted due to a change of equipment such as the racket RA or an accident.

The exercise support apparatus 3 also generates advice for the player PL using the body movement information of the player PL and the movement information of the tool. When an appropriate timing for notifying advice is determined, effective advice is selected and notified to the player PL at that timing. When such advice is present, the entire display area of the display unit 91 is blinked to notify the player PL that the advice is present, and then the wording or image of the advice is displayed.
The exercise support system 1 having such a series of functions will be described in detail below.

(Configuration of exercise support system)
FIG. 3 is a block diagram illustrating a schematic function of the exercise support system. The exercise support system 1 includes a sensor unit 10 and an exercise support device 3, which are connected to each other so as to be able to transmit and receive data by communication 2.

As described above, the sensor units 10A, 10B, 10C, and 10D constituting the sensor unit 10 are each mounted on a tool or the like related to exercise such as tennis.
The sensor unit 10 includes a micro electro mechanical systems (MEMS) sensor such as an acceleration sensor, a gyro sensor, and a ball sensor, a satellite positioning sensor such as a GPS (Global Positioning System), and a communication adapter. These sensors built in the sensor unit 10 are dynamic sensors that are mounted on a tool or the like and detect the movement of the tool.
The sensor unit 10 corresponds to a detection device.

  The acceleration sensor measures a change in acceleration signal in one axis direction or at least two intersecting axis directions every unit time. The gyro sensor measures a change in angular velocity signal about one axis or at least two intersecting axes as a rotation axis every unit time. The ball sensor is a sensor in which a ball of a conductor that is movable is contained in a container having a positive electrode and a ground electrode. When vibration is applied to the container, the presence / absence of conduction is generated as the ball moves. The appearance status of the presence or absence of continuity is output as a ball movement detection signal.

Each MEMS sensor includes an AD (Analog to Digital) conversion circuit and an arithmetic circuit, and converts the detected acceleration signal, angular velocity signal, ball movement detection signal, etc. into acceleration data, angular velocity data, and ball movement detection data. From the data, tool movement data representing the amount of exercise is calculated. The acceleration data and the angular velocity data are calculated from the data representing the momentum by a known method (see Japanese Patent Application Laid-Open Nos. 2004-81632 and 2004-252618). Further, the detection of the ball movement detection signal by the ball sensor and the calculation of the data representing the momentum can be realized by JP 2011-29014 A or the like.
The device activity data calculated in this way is transmitted to the exercise support device 3 via the communication 2 by a wireless communication function (not shown) provided in the sensor unit 10. The tool movement data corresponds to movement information.

The exercise support device 3 includes a body motion detection unit 20, a communication unit 30, a time measurement unit 33, a control unit 40, a storage unit 50, a notification unit 90, and the like.
As a preferred example, the body motion detection unit 20 is a sensor unit including an acceleration sensor, and measures a change in acceleration in one axis direction or at least two axis directions intersecting each unit time. The body motion detection unit 20 calculates various information related to the body motion of the player PL using the acceleration change data, and outputs the information to the control unit 40 as body motion data. Specifically, the body motion detection unit 20 calculates the amount of exercise per unit time of the player PL by integrating the measured amount of change in acceleration. Further, the body motion detection unit 20 may include a gyro sensor, a satellite positioning sensor, and the like, and may be configured to be able to discriminate and measure the body motion of the player PL from various directions. The sensor that constitutes the body motion detection unit 20 is a body motion sensor that is attached to a living body or the like and detects the movement of the living body.
The body motion detection unit 20 is not limited to a configuration including an acceleration sensor, a gyro sensor, and a satellite positioning sensor, but a pulse sensor that detects the pulse rate of the player PL, a temperature sensor that detects external environment information, A pressure sensor or the like may be provided.
The body motion data corresponds to body motion information, and the body motion detection unit 20 corresponds to a body motion information acquisition unit.

The communication unit 30 is a short-range wireless adapter having a common communication protocol with the sensor unit 10, and receives device activity data transmitted from the sensor unit 10. In the communication unit 30, the device activity data received from the sensor units 10 </ b> A, 10 </ b> B, 10 </ b> C, 10 </ b> D is distinguished for each sensor unit and output to the control unit 40.
Note that the communication unit 30 that receives the device movement data corresponds to a movement information collection unit.

  The timekeeping unit 33 is a real-time clock and has timekeeping functions such as a clock function, a timer, and a stopwatch function. In the time measuring unit 33, the sampling period is output to the body motion detecting unit 20 and time information is output to the body motion detecting unit 20, the communication unit 30, and the control unit 40 at any time by a clock function.

The control unit 40 includes a processor such as a CPU (Central Processing Unit), and is a control device and an arithmetic device that collectively control each unit of the exercise support device 3. The control unit 40 realizes various functions of the exercise support device 3 according to various programs (not shown) including the determination program 81 and the output program 83 stored in the storage unit 50. The control unit 40 corresponds to a computer.
The control unit 40 includes functional units such as a motion analysis unit 41, an advice generation unit 43, a timing determination unit 45, and an advice output unit 47. However, these functional units are merely examples, and all the functional units are not necessarily required. Moreover, you may have a function part other than these.

  The motion analysis unit 41 analyzes the motion state of the player PL using part of the body motion data and the tool motion data of the player PL. The exercise state is information on how to exercise such as how the player PL was moving, how much difference it is from the ideal movement, etc., and each piece of information is generated sequentially for each play. Yes. The analyzed exercise state is sequentially output to the advice generation unit 43 for each play as the exercise state information of the player PL. The unit of play in the motion analysis unit 41 and the advice generation unit 43 is one play from the start to the end of each operation such as a swing at receive and a swing at serve. Moreover, even if it is the play of the same category, you may subdivide the kind of play further. For example, in the serve, the first serve and the second serve may be different types of play, or the receive may be a different type of play such as fore hand and bag hand, lob, volley, and stance for each stance.

The advice generation unit 43 generates advice for the play performed by the player PL based on the exercise state information of the player PL that is sequentially output. Further, the advice generation unit 43 also performs invalidation and deletion processing of advice that is no longer necessary in the past advice.
In the advice generation unit 43, when advice is generated for each play, the advice generation unit 43 stores the file in the storage unit 50 as a file such as a moving image or sound. The stored file group is the advice file group 70. The advice generation unit 43 manages each advice file stored using the management table 60. The management table 60 has information indicating whether the advice file is valid or invalid, and the information is updated by the advice generation unit 43.
Even if the advice file is valid at the time of generation, it becomes past information every time the play progresses, or it has been improved by the player PL before notifying the generated advice. It is invalidated by the advice generation unit 43.
The processing for determining invalidity of advice may be performed by a method in which an expiration date or validity condition of advice is set at the time of advice generation and invalidated when the expiration date or validity condition is no longer satisfied.

  The processing for generating advice for the player PL from the body movement data and the tool movement data in the exercise analysis unit 41 and the advice generation unit 43 is disclosed in Japanese Patent Laid-Open No. 2013-27629.

Here, a specific function of the advice generation unit 43 will be described with reference to FIG.
FIG. 4 is an explanatory diagram showing a management table and an advice file group. The management table 60 is a table for managing information related to the generated advice, and includes items of ID 61, valid flag 63, and link destination 65. The ID 61 is an identifier assigned for each generated advice. The valid flag 63 is a flag indicating whether the advice is valid “1” or invalid “0”. The link destination 65 is link destination information to an advice file in which the generated advice is stored. As the advice file group 70, a moving image A file 71, an oral instruction file 72, a moving image B file 73, an image file 74, a wording file 75, an audio file 76, and the like are illustrated. When the moving image A file 71 and the moving image B file 73 are output to the notification unit 90, the moving image is reproduced, the image file 74 displays an image, and the audio file 76 reproduces sound. In the text file 75, the text is displayed on the display unit 91. The verbal instruction file 72 represents that there is a verbal direct instruction from the coach instructing the player PL. Specifically, a message such as “There is advice from the coach” is displayed on the display unit 91.

When the advice generation unit 43 generates an advice file as an advice file group 70 for each play, the advice generation unit 43 adds one row to the management table 60, stores “1” in the validity flag 63 of the added ID 61, and advises the link destination 65. Stores the link destination information of the file.
Further, the advice generation unit 43 also performs batch processing for deleting the row of the ID 61 in which the valid flag 63 becomes invalid “0” at predetermined intervals (for example, every one minute).
In this way, the management table 60 is managed by the advice generation unit 43 so that an advice file that is always the latest and valid for the player PL can be provided regardless of the timing.

Returning to FIG. 3, the timing determination unit 45 will be described.
The timing determination part 45 determines the timing which alert | reports advice using apparatus dynamics data and the body movement data of player PL. Specifically, the play action index of the player PL is calculated using the tool movement data in which the movement of the racket RA, the racket RB, the ball BA, and the bag BG at the predetermined time is detected, and the body movement data of the player PL. The play action index is an index that can identify the play status of the player PL, such as whether or not it is a time zone during which the player PL is taking a rest. For example, the play action index is an index that can be used to determine such a state when the ball BA or the racket RA or RB is moving even if the body movement data of the player PL is not moving. . On the other hand, by analyzing the play action index, it is possible to determine a state where the player PL is resting between play, and such a state is a state in which advice can be received. There is a timing for notifying advice in such a time zone.

This will be described with reference to FIGS.
FIG. 5 is an explanatory diagram regarding timing determination. FIG. 6 is a detailed explanatory diagram regarding timing determination.
In the graphs of FIGS. 5 and 6, the horizontal axis represents time t indicating the passage of time, and the vertical axis represents the amount of exercise per unit time at time t. FIG. 5A represents the amount of exercise RA (t) of the racket RA (sensor unit 10A) at time t. Similarly, FIG. 5B shows the momentum RB (t) in the racket RB (sensor unit 10B), FIG. 5C shows the momentum BA (t) in the ball BA (sensor unit 10C), and FIG. Represents the momentum BG (t) in the bag BG (sensor unit 10D). FIG. 5E shows the amount of exercise PL (t) at time t of the player PL. FIG. 5 (f) represents the play action index M (t) of the player PL at time t. The timing determination unit 45 analyzes the increasing / decreasing tendency of the play action index M (t) and determines the timing for notifying the advice.

In the timing determination unit 45, the play action index M (t) is calculated by the following equation 1.
M (t) = RA (t) + RB (t) + BA (t) −BG (t) + PL (t) (Equation 1)

The play action index M (t) is calculated when the player PL is playing, when either the racket RA or the racket RB is used, the ball BA is moving, or the player PL is moving. (T), RB (t), BA (t), and PL (t) are added. Further, the play action index M (t) is subtracted from BG (t) when the bag BG is used while the player PL is resting.
Formula 1 is an example, and the calculation is performed in the direction of adding the momentums RA (t), RB (t), BA (t), and PL (t) that have a positive correlation with the play action of the player PL. As long as the play motion index M (t) is calculated by reducing the amount of exercise BG (t) that shows a negative correlation with the play motion, the other arithmetic expressions can be applied.

  Next, the process of determining the timing for notifying the advice will be described taking the interval between time t1 and t2 when the play motion index M (t) is decreasing in FIG. 5 and between time t3 and t4 as an example. . The timing determining unit 45 determines that there is no appropriate timing for notifying the advice between the times t1 and t2, and the time t4 notifies the advice between the times t3 and t4. It is determined that it is timely.

Details will be described with reference to FIG.
The graph shown in FIG. 6A represents a curve Ma obtained by enlarging the play action index M (t) at times t1 to t2 shown in FIG. 5F, and the graph shown in FIG. The curve Mb which expanded the play action parameter | index M (t) in the time t3-t4 shown to (f) is represented.
The inflection point CP shown in FIG. 6 is a point at which the decreasing tendency of the play action index M (t), which has been decreasing with the passage of time t, has been eliminated. Specifically, the timing determination unit 45 calculates a differential value (slope of M (t) at time t) of the play action index M (t) that changes with the lapse of time t, and the differential coefficient is a negative value. The inflection point CP is a point on the curve that has changed from zero to zero or positive value.
The predetermined period THC is a value in which the time elapsed from the time of the inflection point CP is defined.
The predetermined motion amount THM is a threshold value for determining whether or not the player PL is resting, and is a value in which the motion amount based on the inflection point CP in the play motion index (vertical axis) is defined.
The evaluation point EP is a point on the curve at the time when a predetermined period THC has elapsed from the time of the inflection point CP.
In the following description, the play action index M (t) is abbreviated as M (t).

The timing determination unit 45 determines that the player PL is resting if the M (t) of the evaluation point EP is equal to or less than the value obtained by adding the predetermined movement amount THM to the M (t) of the inflection point CP. On the other hand, when M (t) of the evaluation point EP exceeds, it is determined that the player PL has not rested but has shifted to the next play.
A specific example will be described with reference to FIGS.
FIG. 6A shows an example in which it is determined that the latter player PL is not resting and has shifted to the next play. Since M (t2) of the evaluation point EP on the curve Ma exceeds the value obtained by adding the predetermined operation amount THM to M (t1) of the inflection point CP, the player PL does not take a rest and proceeds to the next play. It is determined that it has migrated.
FIG. 6B shows an example in which it is determined that the former player PL is resting. Since M (t4) of the evaluation point EP on the curve Mb is equal to or less than the value obtained by adding the predetermined operation amount THM to M (t3) of the inflection point CP, it is determined that the player PL is resting. Yes. Since the player PL is resting, the player PL can accept advice. That is, time t4 is an appropriate timing for notifying advice.
At time t2 of the evaluation point EP shown in FIG. 6A, since the player PL has shifted to the next play, even if advice is generated, it is inappropriate as a timing for notifying the advice. At time t4 of the evaluation point EP shown in FIG. 6B, it is appropriate as a timing for notifying the advice. When a valid advice file exists with reference to the management table 60 at this timing, the advice is sent to the player. Notify PL.

Returning to FIG. 3, the explanation of the advice output unit 47 is started.
The advice output unit 47 is a functional unit that is executed with the timing determined by the timing determination unit 45 as a trigger, and selects an advice file that is effective at the time of execution (determined timing) and notifies the notification unit 90 of the effective advice file. Output. Specifically, when executed, the advice output unit 47 refers to the management table 60 and repeats the ID 61 from “1” to the final number in order. In the repeated processing, when the valid flag 63 is “1”, the file of the link destination 65 is read from the advice file group 70. The read target advice file is output to the notification unit 90. When ID 61 is repeated up to the final number, all valid advice files are output at the determined timing, and the player PL can confirm the notified file.

The storage unit 50 includes a storage device such as a ROM (Read Only Memory), a flash ROM, a RAM (Random Access Memory), a HDD (Hard Disk Drive), an SSD (Solid State Drive), and the like. Various programs, various files, etc. for realizing are stored. In addition, it has a work area for temporarily storing data being processed and results of various processes.
The storage unit 50 stores the management table 60, the advice file group 70, and the like described above. In addition, programs such as a determination program 81 and an output program 83 are stored.
The determination program 81 is read and executed by the control unit 40, thereby realizing the function of the timing determination unit 45 included in the control unit 40.
The output program 83 is a program that is called from the determination program 81 and executed, and the function of the advice output unit 47 is realized by being read and executed by the control unit 40.
The processing of the determination program 81 and the output program 83 will be described later using a flowchart. The determination program 81 and the output program 83 together correspond to an exercise support program.

(Exercise support method flow)
Next, the exercise support method will be described with reference to FIGS.
FIG. 7 is a flowchart showing the flow of timing determination processing. FIG. 8 is a flowchart showing the flow of advice output processing.
The flow shown in FIG. 7 is a flow of processing realized by the determination program 81 being read and executed by the control unit 40. The flow shown in FIG. 8 is a flow of processing realized by the output program 83 being read and executed by the control unit 40.
6A and 6B, the flow starts from a state in which the curve Ma and the curve Mb are decreasing (differential coefficient is negative), and detects the inflection point CP. The process until notification of advice is described. The description of the process of determining whether or not the curve Ma and the curve Mb are in a decreasing tendency is omitted.

  In step S110, the variable CNT and the variable CX are initialized. Specifically, the variable CNT is a variable that counts the time elapsed from the time of the inflection point CP. In this step, “0” is set as the initial state. The variable CX is a variable that can confirm that the inflection point CP has appeared. In this step, “NULL” is set as the initial state. During the period from the inflection point CP to the evaluation point EP (referred to as inflection point processing), the contents of M (t) are set in the variable CX, and when the evaluation point EP is exceeded, “NULL” is set again. Set.

  In step S120, device movement data and body movement data are acquired. Specifically, RA (t), RB (t), BA (t), and BG (t) are received from the sensor unit 10 as device activity data at time t. Also, PL (t) is acquired from the body motion detection unit 20 as the body motion data at time t.

  In step S130, M (t) is calculated, and the index value is substituted into the variable MX. Specifically, M (t) at time t is calculated using the above-described formula 1, and is substituted into the variable MX.

  In step S140, it is determined whether inflection point processing is being performed. Specifically, it is determined whether or not the content of the variable CX is “NULL”. If it is “NULL”, since the inflection point processing is not in progress (Yes), a new inflection point CP is detected. The process proceeds to step S150. If the content of the variable CX is not “NULL”, the inflection point process is being performed (No), and the process proceeds to step S180 in order to count the time from the inflection point CP.

  In step S150 and step S160, it is determined whether the variable MX is an inflection point. Specifically, the differential coefficient at time t is calculated with reference to past play action index values such as M (t−1) used in the previous loop. If the differential coefficient is zero or positive, the variable MX is determined to be the inflection point CP (Yes), and the process proceeds to step S170. If the differential coefficient is a negative value, it is determined that the variable MX is not the inflection point CP (No), and the process proceeds to step S120 in order to acquire the next device movement data and body movement data.

  In step S170, the processing of the inflection point is set. The contents of the variable MX of the inflection point CP that has appeared are set in the variable CX. Since the contents of M (t) are set in the variable CX, it indicates that the inflection point process is being performed.

  In step S180, the time from the inflection point is measured. Specifically, the contents of the variable CNT are incremented.

  In step S190, it is determined whether or not the variable CNT is longer than a predetermined period THC. Specifically, the count number corresponding to the time of the predetermined period THC is stored in the predetermined period THC, and when the variable CNT exceeds the predetermined period THC (Yes), the variable MX is the evaluation point EP. Proceeding to step S200, the variable MX is evaluated. If not exceeded (No), the process proceeds to step S120 to obtain the next device movement data and body movement data.

  In step S200, it is determined whether or not the difference between the variable MX and the variable CX is equal to or less than a predetermined operation amount THM. Specifically, when the difference amount of the play action index value between the variable CX (inflection point CP) and the variable MX (evaluation point EP) is equal to or less than the predetermined action amount THM, the evaluation point EP is notified of advice. It is a suitable timing. Therefore, if it is equal to or less than the predetermined motion amount THM (Yes), the process proceeds to step S210, and advice is output. If the predetermined motion amount THM is exceeded (No), the player PL has shifted to the next play. The next tool movement data and body movement data are acquired, and the process proceeds to step S110 to detect a new inflection point CP.

  In step S210, advice is output. The process of step S210 will be described in detail with reference to FIG.

  In step S220, it is determined whether or not the play has ended. If the player PL has performed an operation indicating that the play has been completed, or if the movement of the acquired device movement data and body movement data has not changed for a certain period of time, it is determined that the play has ended (Yes), and this flow ends. When that is not right (No), it progresses to step S110, the following tool movement data and body movement data are acquired, and the new inflection point CP is detected.

Turning to FIG.
When step S210 described above is executed, the process proceeds to step S310.
In step S310, the management table is accessed. Specifically, each element of the ID 61, the valid flag 63, and the link destination 65 is read from the management table 60 stored in the storage unit 50 into an internal variable or the like.

  In step S320, the number of advices is repeated. Specifically, the loop processing for the number of elements of ID61 is set. The loop processing is repeated from step S320 to S360 for the number of elements of ID61.

  In step S330, a valid flag is acquired and stored in variable FL. The variable FL is an internal variable that temporarily stores a valid flag. The contents (“1” or “0”) of the valid flag 63 are acquired and set to the variable FL.

  In step S340, it is determined whether the variable FL is greater than zero. Specifically, if the content of the variable FL is greater than 0 such as “1” (Yes), the process proceeds to step S350 to notify the advice file of the link destination 65, and the content of the variable FL is “0”. When it is 0 or less (No), the process proceeds to step S360 to process the next advice without notifying the target advice.

  In step S350, the linked advice file is output. Specifically, the advice file indicated by the link destination 65 is designated and output to the notification unit 90. In the notification part 90, the output according to the kind of advice file is performed.

  In step S360, if the number of advices is repeated, the process ends. Until the number of advices is repeated, the process returns to step S320 to repeat the process.
