It is not limited to this. The information collected by the behavior detection device 20 may be finally sent to the behavior analysis device 50. For example, an information relay device may be provided near the position of the charging device 31 of the club bag 30 shown in FIG. The information relay device is a device that delivers information collected by the behavior detection device 20 of the club 10 to the behavior analysis device 50. The information relay device is a club bag 30.
When the storage of the club 10 is detected, the behavior detection device 20 of the club 10 is accessed, and behavior information 110 (output information of each sensor) collected by the behavior detection device 20 is acquired and temporarily stored in its own storage device. . Then, when connected to the behavior analysis device 50, the behavior information 110 (output information of each sensor) stored in the storage device is transmitted to the behavior analysis device 50. Such an information relay apparatus can be achieved by a computer having a CPU, a memory, a ROM, and a communication interface.

<Description of Operation> Next, the operation of the swing evaluation support system configured as described above will be described. First, the collection processing of the behavior information 110 of the behavior detection device 20 of the club 10 will be described with reference to the flowchart of FIG.

When the switch 27 is turned on by the player, the main control unit 21 of the behavior detection device 20
Measurements by the two gyro sensors 22h and 22g and the two acceleration sensors 23h and 23g are started (S12). Then, while the measurement is being performed, the switch OFF is monitored. If the switch is turned off (Y in S13), the measurement is terminated, and the measurement result up to that point is stored in the storage device 28 (S14). Exit.

FIG. 5 shows the behavior information 110 accumulated in the storage device 28 of the behavior detection device 20. In S14 of FIG. 4, the main control unit 21 adds the record 111 to the behavior information 110, and in the added record 111, a code (record ID) 112 for identifying the record, a code for identifying the club (club ID 113), The recording date and time 114 acquired by the clock 25 and the behavior data 115 including the output from each sensor are stored.

In the behavior data 115, as shown in FIG.
3), the three-axis detection result 123 of the gyro sensor 22h of the head portion 11, the three-axis detection result 124 of the acceleration sensor 23h, and the three-axis detection of the gyro sensor 22g of the grip portion 13 Triaxial detection result 1 of the detection result 125 and the acceleration sensor 23g
26 are stored.

In this way, the record 111 is added to the behavior information 110 every time the switch 27 is turned on / off and the club 10 is swung.

  Next, the operation of the behavior analysis apparatus 50 will be described.

The input / output IF 54 of the behavior analysis device 50 acquires the accumulated behavior information 110 from the behavior detection device 20 of the club 10 via the wireless device, and stores it in the history information 55.

Next, a case where a swing evaluation request is received from the user will be described. The behavior evaluation unit 2 performs, for example, the following processing according to the type of request.

(1) Display of specific swing behavior FIG. 7 shows a processing flow in such a case. The behavior evaluation unit 53 first causes the user to select the record 111 to be evaluated from the behavior information 110 stored in the history information 55 (S20). At this time, candidates can be narrowed down using the recording date 114 as a key. For example, when an instruction for a recording date / time range is received from the user, the recording date / time 11 falls within the specified range.
A record 111 having 4 is extracted and displayed as a candidate. A selection is accepted from the candidates.

Next, the behavior evaluation unit 52 identifies a model that is the closest to the behavior data 115 of the selected record 111 (S21). Here, as shown in FIG. 8, the behavior data 152 at the time of swing is stored in the model behavior data 150 for each model ID 151. The behavior data 152 has the same configuration as the behavior data 115 shown in FIG. The model behavior data 150 is data collected experimentally, and stores the output of each sensor when various swings are performed using the club 10 with one swing as one model. The behavior evaluation unit 52 extracts behavior data 152 that most closely approximates the behavior data 115 to be evaluated from the model behavior data 150. For example, for the model behavior data 152 and the behavior data 115 to be evaluated, all the differences in the values of the axes of the sensors at the same elapsed time 153 and 122 are obtained, and all the differences fall within a predetermined range. ID 151 is specified. When a plurality of models are specified, a model ID 151 that minimizes the sum of differences is further specified.

Next, the behavior evaluation unit 52 acquires evaluation data corresponding to the model ID identified in S21 from the evaluation model data 160. Here, as shown in FIG. 9, the evaluation data 160 includes a head speed 16 for each model ID 161 (corresponding to the model ID 151).
2, flight distance 163, drawing data 164, evaluation 165, comment 166, and the like.
The evaluation data 160 is created by actually measuring the head speed and the flight distance during the swing of each model. The drawing data 164 is an image showing the state of the swing. The evaluation 165 is an evaluation related to the swing, and is represented by, for example, a numerical value in five stages. Comment 166
Contains messages such as what to do for a better swing.

Next, as shown in FIG. 10, the behavior evaluation unit 52 displays various information on the screen 510 of the display device using the evaluation data selected in S22. For example, using the drawing data 164 as the swing image 521, the state of the swing is displayed by animation or the like.
Fast forward and rewind, quick playback and slow playback may be accepted and executed. Further, the head speed 162, the flight distance 163, the evaluation 165, and the comment 166 are displayed as the additional information 530. At this time, as the identification information 520 of the selected record 111, the club ID 113 and the recording date 114 of the evaluation target record 111 may be displayed.

(2) Comparison of a plurality of behavior data In this case, the behavior evaluation unit 52 causes the user to select a plurality of (for example, two) records 111 from the behavior information 110 accumulated in the history information 55. Then, the above-described evaluation data is selected for each selected record 111. Furthermore, FIG.
As shown in FIG. 4, the identification information 520a, 520b of each selected record 111,
The swing images 521a and 521b are displayed. Further, a difference (head speed difference, flight distance difference) may be obtained and displayed as difference information 531. Note that the behavior evaluation unit 52 may display a plurality of swing images side by side, or may display a predetermined part (for example, the position of both feet) so as to overlap each other.

(3) Comparison with Pro Golfer's Swing Behavior As shown in FIG. 12, the behavior evaluating unit 52 can display a comparison between the evaluation target swing and the pro golfer's swing using the pro golfer data 170. As shown in FIG. 13, the professional golfer data 170 includes a profile 172 and a model ID 173 for each golfer ID 171. The profile 172 includes information on the physique such as height and weight in addition to the name and achievement of the professional golfer. Model ID
Reference numeral 173 corresponds to the model ID 151 of the model behavior data 150 and the model ID 161 of the evaluation data 160.

The behavior evaluation unit 52 causes the user to select the evaluation target record 111 from the behavior information 110. Then, the above-described evaluation data is selected for the selected record 111, and the identification information 520 and the swing image 521 are displayed as shown in FIG.
The additional information 530 is displayed. Further, the user is made to select the professional golfer ID 171 from the professional golfer data 170 using the name of the profile 172 as a key.
Then, from the evaluation data 160, the evaluation data corresponding to the selected professional golfer ID 171 is specified using the model ID 161 (model ID 173) as a key. Then, by using the drawing data 164 of the specified evaluation data, the swing image 5 of the professional golfer
22 is displayed. Further, a difference (head speed difference, flight distance difference) between the evaluation data of the evaluation target record 111 and the evaluation data of the designated professional golfer is obtained, and the difference information 5
You may display as 31. The behavior evaluation unit 52 may display the two swing images side by side, or may display the predetermined parts (for example, the positions of both feet) so as to overlap each other.

(4) Identification of approximated professional golfer Further, it is possible to identify and display a professional golfer who makes the most approximate swing. For example, the behavior evaluation unit 52 uses the professional golfer data 170 to generate the model behavior data 15.
The professional golfer's behavior data 152 is extracted from 0, and the one closest to the behavior data 115 to be evaluated is identified from the extracted behavior data 152 in the same manner as (1). Then, from the professional golfer data 170, the model I of the identified behavior data 152 is determined.
The professional golfer ID 171 corresponding to D151 is specified. Then, as shown in FIG. 12, information 535 indicating the recent professional golfer is displayed. At this time, the profile 172 of the professional golfer may be displayed. Then, the user can know the physique difference from himself.

As mentioned above, although some processes of the behavior evaluation part 52 were demonstrated, the behavior data 115 can be evaluated and analyzed from various viewpoints according to the request | requirement from a user besides these.
The data used for evaluation and analysis is not limited to the model behavior data 150, the evaluation table data 160, and the professional golfer data 170.

  The embodiment of the present invention has been described above.

According to the embodiment, it is possible to know the behavior of the golf club during a swing without using a highly sensitive camera. Even if you try to image the swing behavior with a camera like before,
Although it may be hidden by an obstacle, this embodiment does not have this problem.

Further, since a golf club bends and twists depending on the material of the shaft, the positional relationship between the grip portion and the head portion changes. According to this embodiment, a sensor is provided between the grip portion and the head portion. Since it is installed, the swing behavior can be detected and evaluated more accurately regardless of bending or twisting.

  The present invention is not limited to the above embodiment. Below, the modification of the said embodiment is demonstrated.

<Modification: Measurement timing>
In the above embodiment, the measurement period of each sensor is the period from ON to OFF of the switch 27, but is not limited to this. For example, a predetermined period after the switch 27 is turned on may be set as the measurement time. In addition, a period during which the club 10 is away from the charging device 31 (that is, a period during which power is being supplied and whether power is being supplied) may be set as the measurement time.

Moreover, you may make it the main control part 21 of the behavior detection apparatus 20 determine the range recorded on a record, always measuring with each sensor. For example, when a swing is performed, a time range to be stored as one record is determined, and the sensor output measured in the time range is stored in the record 111 as one swing. The recording time range can be set in the same manner as the measurement time described above.

Moreover, the range of the time which detects the impact on a ball | bowl and memorize | stores as 1 record may be set. For example, the impact on the ball is detected by an impact detection sensor (which may also be used as the gyro sensor 22h or the acceleration sensor 23h of the head unit 11 or may be a pressure sensor or a contact sensor). Time is set as the range of recording time for one record.

Further, the head speed may be used. For example, the acceleration sensor 23h of the head unit 11
When a predetermined acceleration is detected, a predetermined time before and after is set as a recording time range of one record.

<Modification: Club with output device>
As shown in FIG. 14, the behavior detection device 20 may have the function of the behavior analysis device 50 described above. That is, the behavior detection device 20 includes a main control unit 21, a gyro sensor 22h,
2g, acceleration sensors 23h and 23g, a storage battery 24, a clock 25, an input / output IF (interface) 26, a storage device 28, and a behavior evaluation unit 52. The storage device 28 stores history information 55, model behavior data 150, evaluation data 160, and professional golfer data 170. The processing performed by each functional unit is the same as that in the above-described embodiment. However, the club 10 cannot have a display that a personal computer has.

Therefore, the club 10 is used as an output device as shown in FIG.
In addition, a small display device 18 and a speaker 19 are incorporated. The small display device 18 may be capable of displaying characters or may be a light emitting element such as an LED (a laser light emitting diode).

Various settings of the behavior detection apparatus 20 may be performed by a wireless remote controller. For example, the remote controller holds the updated model behavior data 150 and the professional golfer data 170 in its own storage device, and the input / output IF2 of the behavior detection device 20 in response to a request from the user.
6 to send. The main control unit 21 stores the received information in the storage device 28.

  FIG. 16 is a flowchart of the operation of the behavior detection apparatus 20 when the swing operation is performed.

The main controller 21 performs behavior information storage processing in the same manner as the flow of FIG. 4 (S31).
As a result, as shown in FIG. 5, the record 111 is added to the behavior information 110 and the behavior data 115 is stored.

Next, the behavior evaluation unit 52 performs the behavior data 11 obtained in S31 in the same manner as described above.
5 is evaluated (S31, S33). And an evaluation result is output via the output devices 13 and 14 (S34). The method of evaluation here and the way of outputting the evaluation differ depending on the setting method.

(1) Output of evaluation information In this case, the behavior evaluation unit 52 obtains evaluation data of the behavior data 115 to be evaluated by the above-described method, and the head speed 162, the flight distance 163, the evaluation 165, and the comment 16
6 etc. are output by an output device. For example, the speaker 19 utters voice. Or
Displayed on the small display device 19. When the small display device 19 is a light emitting element, it is lit in a predetermined mode (color or number of blinks) according to the output contents.

(2) Comparison with past swing When the swing is performed and the behavior data 115 is newly generated, the behavior evaluation unit 52 compares it with the past behavior data 115 stored in the history information 55. For example, the most recorded date 1
14 retrieves another new record 111, obtains evaluation data for both, and obtains the degree of difference (difference) between the head speed 162 and the flight distance 163. And according to the degree of difference,
A predetermined message is uttered by voice through the speaker 19. For example, if this time is slow, say "Head speed is slow". Or small display device 1
8 is displayed. Alternatively, it is lit in a predetermined mode (color or number of blinks) according to the output content.

(3) Pro Golfer's Swing and Comparison When the swing is performed and the behavior data 115 is newly generated, the behavior evaluation unit 52 compares it with the pro golfer's behavior data 152 registered in the pro golfer data 170. In addition, when the behavior data 152 of a some professional golfer exists, it compares with what was previously selected by the user. For example, for the newly generated behavior data 115 and the professional golfer's behavior data 152, evaluation data is obtained, and the difference (difference) between the head speed 162 and the flight distance 163 is obtained. And according to a difference degree, a predetermined message is uttered by the sound with the speaker 19. For example, if the head speed is fast,
Say, "It is faster than the head speed of professional golfer ***." Alternatively, the image is displayed on the small display device 18. Alternatively, it is lit in a predetermined mode (color or number of blinks) according to the output contents.

(4) Identifying Pro Golfer with Approximate Swing When the swing is performed and the behavior data 115 is newly generated, the behavior evaluating unit 52, like the above method, the pro golfer corresponding to the most approximate behavior data 152 The golfer ID is specified. Then, with reference to professional golfer data 170, profile 1
The name is acquired from 72 and, for example, the speaker 19 utters “It is close to the swing of a professional golfer **”. Alternatively, the image is displayed on the small display device 18. This way
Each time the player swings, the player can know an approximate professional golfer.

  In the above, some modified examples have been described.

In the clubs of the above-described embodiment and the modified example, it is only necessary that the triaxial gyro sensor is disposed at least in two places, the head portion and the grip portion (or the shaft portion), and the acceleration sensor may not be provided. . You may make it provide an acceleration sensor only in a head part.
