The CPU controls each unit connected to the control unit 20 by executing a control program stored in the ROM using the RAM as a working area. Specifically, the control unit 20 adds data indicating the reference azimuth to the voltage value indicating the magnetic field output by the azimuth detection unit 22 when the reference azimuth setting switch 2c is pressed (hereinafter, referred to as “reference azimuth”). (Referred to as reference orientation information) is transmitted to the rotation analyzer 3. In addition, after the output of the reference azimuth information, information indicating that the azimuth is in rotation is added to the voltage value indicating the magnetic field output by the azimuth detection unit 22 at regular intervals, and the data (hereinafter referred to as the rotation azimuth) is added.

In addition to the control program, the ROM stores an orientation conversion table 310 shown in FIG. The azimuth conversion table 310 stores an azimuth corresponding to a voltage value G (Gx, Gy, Gz) indicating a magnetic field in association with a clockwise azimuth angle with respect to the north. Based on the azimuth conversion table 310, the reference azimuth information received from the rotation detection belt 2, and the rotation azimuth information sequentially transmitted from the rotation detection belt 2, the control unit 30 is an azimuth angle that is a change in azimuth from the reference azimuth.

Based on the condition information, it is determined whether or not the rotation operation (number of rotations and rotation time) is a predetermined rotation operation mode defined in the rotation condition information, and notification is made based on the determination result.

The rotation time detection unit 31 receives a control signal indicating the start and end of time measurement from the control unit 30 and counts a predetermined clock. The communication unit 32 is a Bluetooth (registered trademark) wireless communication interface, and under the control of the control unit 30, authenticates the ID number transmitted from the rotation detection belt 2 and establishes a connection with the rotation detection belt 2.

Here, the rotation condition information and the notification sound information will be described with reference to FIG. FIG. 6A shows the configuration and data example of the rotation condition information. The rotation condition information 320 stores the rotation speed and the rotation time (operation time) as rotation information corresponding to each rotation operation mode, and is referred to when determining the rotation operation of the rotation detection belt 2. For example, in the case of the rotation operation mode of two rotations (autorotation), if two rotations are detected within the rotation time t2, it is determined that the two rotations are successful.

  Next, the notification sound information will be described. In FIG. 6B, the notification sound information 330 includes a determination result indicating whether or not the rotation operation of the rotation operation mode defined in the rotation condition information 320 is successful, and a notification sound corresponding to each determination result.

The notification sound information 330 is not limited to sound but may be sound data.

  Returning to the description of FIG. Under the control of the control unit 30, the audio processing unit 34 converts the audio data stored in the notification sound information 330 into an audio signal and sends it to the speaker 35. The speaker 35 includes an amplifier (not shown), and amplifies and outputs the audio signal sent from the audio processing unit 34. The display unit 36 includes a display such as a liquid crystal display, and displays various images such as a selection screen for selecting the type of rotation operation to be determined under the control of the control unit 30. The operation unit 37 is an input interface such as a keyboard and a mouse, and accepts an input operation from the user.

(Operation)
Next, the operation of the rotational motion analysis apparatus 1 in the present embodiment will be described. FIG. 7 is a diagram showing a rotational motion analysis processing flow of the rotational motion analysis device 1. The control unit 30 of the rotation analysis device 3 reads the rotation operation mode of the rotation condition information 320 stored in the storage unit 33, displays a selection screen for selecting the rotation operation mode on the display unit 36, and selects from the user. Accept (step S20). In the following description, it is assumed that the user has selected the rotation operation mode of two rotation turns.
When the user wears the rotation detection belt 2 on the body and presses the reference azimuth setting switch 2c (step S10: YES), the azimuth detection unit 22 of the rotation detection belt 2 detects geomagnetism and outputs a voltage value indicating the magnetic field. Then, the control unit 20 rotates the transmission data to which the reference direction information including the voltage value indicating the magnetic field output from the direction detection unit 22 and the ID number of the rotation detection belt 2 are added via the communication unit 23. It transmits to the analysis apparatus 3 (step S12). If the reference azimuth setting switch 2c is not pressed (step S10: NO), the rotation detection process is terminated after a predetermined time has elapsed.

  When the rotation analysis device 3 receives the reference orientation information and the ID number of the rotation detection belt 2 transmitted from the rotation detection belt 2 (step S21: YES), the rotation analysis device 3 authenticates the ID number of the rotation detection belt 2 and stores it in the ROM. With reference to the orientation conversion table 310, the orientation corresponding to the received reference orientation information is specified as the reference orientation and stored in a predetermined area of the RAM (step S22). At this time, for example, when the user presses the reference direction setting switch 2c toward “north”, information indicating “north” is stored as the reference direction. In addition, when reference azimuth | direction information is not received in step S21 (step S21: NO), a rotation operation | movement analysis process is complete | finished after progress for a predetermined time.

  The user performs a rotation operation after pressing the reference azimuth setting switch 2c. The direction detection unit 22 of the rotation detection belt 2 detects the geomagnetism that changes every moment as the user rotates (step S13), and the control unit 20 uses the direction detection unit 22 to detect the geomagnetism. The rotation direction information output sequentially is transmitted to the rotation analysis device 3 via the communication unit 23 (step S14). The control unit 20 repeatedly performs the processing from step S13 onward until the reference azimuth setting switch 2c is pressed again by the user (step S15: NO), and when the reference azimuth setting switch 2c is pressed again (step S15: YES), the transmission of the rotation direction information is stopped, and the rotation detection process is terminated.

  When receiving the rotation direction information transmitted from the rotation detection belt 2 via the communication unit 32 (step S23: YES), the control unit 30 of the rotation analysis device 3 refers to the direction conversion table 310 stored in the ROM. The direction corresponding to the rotation direction information (hereinafter referred to as the rotation direction) is specified. Further, with reference to the reference azimuth stored in the RAM, it is determined whether the specified rotation azimuth has changed from the reference azimuth and rotation has started (step S24). The determination as to whether or not the rotational orientation has changed from the reference orientation may be made, for example, if the rotational orientation does not match the reference orientation, it may be determined that the rotational orientation has changed from the reference orientation. It may be determined that the angle has changed from the reference azimuth if the angle has changed by more than the angle, for example, 5 ° or more.

  In step S24, when it is determined that the rotation has started (step S24: YES), the control unit 30 sends a control signal for starting the time measurement to the rotation time detection unit 31, and the rotation time detection unit 31 performs the rotation time. The time information measured at the time of receiving each rotation direction is sequentially associated with the rotation direction received from the rotation detection belt 2 sequentially from the rotation direction determined to have started the rotation, and sequentially stored in the RAM. Store (step S25). Then, the control unit 30 analyzes and determines the rotation operation mode for the user's rotation operation (step S26). If it is determined that the rotation direction has not changed from the reference direction and rotation has not started (step S24: NO), the rotation direction information is continuously received until a predetermined time has elapsed, The rotational motion analysis process ends after a predetermined time has elapsed.

Hereinafter, the analysis and determination processing of the rotation operation mode in step S26 will be described with reference to FIG. The control unit 30 of the rotation analysis device 3 reads the reference azimuth and the rotation azimuth stored in the RAM in time series, and detects the rotation speed based on the reference azimuth and the rotation azimuth (step S271). Specifically, the azimuth angle from the reference azimuth is obtained for the read rotation azimuth as the amount of azimuth change from the reference azimuth, and it is determined whether or not the obtained azimuth angle has reached 360 °. For example, the time series data of the reference azimuth from the reference azimuth of the rotation azimuth received sequentially is “0 °, 1 °, 2 °... 35 °... 94 °. If it is “° 265 °”, it has not yet reached 360 °, so it is not recognized as one rotation, and subsequently “265 ° 356 ° 360 °” and 360 °. Is recognized as one rotation. In this way, the rotation is detected in the second and subsequent rotations, and the number of rotations is added and stored in the RAM every time one rotation is detected.
If the azimuth angle of the first rotation does not reach 360 ° and the rotation azimuth to be read next is not stored in the RAM, it is assumed that one rotation could not be detected, and the rotation speed is set to 0. Alternatively, the angle of the azimuth that can be rotated may be stored.
Even when the azimuth angle of the first rotation is less than 360 °, the detected azimuth angle is not less than a predetermined azimuth angle and the rotation azimuth to be read next is stored in the RAM. Is counted as one revolution.
This processing takes into consideration that the azimuth angle of 360 ° may not always be detected depending on the interval and accuracy of detecting the azimuth. For example, the last detected azimuth angle is 356 ° and the next detected azimuth angle When the first azimuth angle of the second rotation is detected without being less than 360 °, such as when the angle is 15 °, this is regarded as one rotation.

And the control part 30 judges whether the rotation speed memorize | stored in RAM is 2 (step S272), and when it judges that the rotation speed is not 2 (step S272: NO), RAM Is read (step S273), and step S271 and subsequent steps are repeated until all rotation directions are read (step S273: NO). If it is determined that the rotation speed is 2 (step S272: YES), the time information associated with the rotation direction from the rotation start that is the target of the rotation speed is read, and each rotation direction is The rotation time t until two rotations are calculated from the time information, the rotation condition information 320 stored in the storage unit 33 is read (step S274), and the rotation time t2 and the rotation time corresponding to the rotation operation of two rotations t is compared to determine whether or not the two-turn turn is successful (step S275).
When the rotation time t is within the rotation time t2 (step S275: YES), the control unit 30 determines that the two-turn turn is successful, and sends a control signal for stopping the time measurement by the rotation time detection unit 31. (Step S276). In addition, when all the rotation directions are read in step S273 (step S273: YES), or when the rotation time t is not within the rotation time t2 (step S275: NO), the control unit 30 makes two rotation turns. It determines with having failed and sends out the control signal which stops the time measuring by the rotation time detection part 31 (step S277).

  Returning to FIG. If the determination result in step S26 is a successful rotation (step S27: YES), the control unit 30 in the notification sound information 330 stored in the storage unit 33, the audio data of audio 1 indicating that the rotation operation has been successful. And the audio processor 34 outputs the audio signal of audio 1 from the speaker 35 (step S28). Moreover, if the determination result in step S26 is rotation failure (step S27: NO), in the notification sound information 330 stored in the storage unit 33, audio data of audio 2 indicating that the rotation operation has failed is read out, The audio processor 34 outputs an audio signal of audio 2 from the speaker 35 (step S29).

In the above-described embodiment, the user simply attaches the rotation detection belt 2 and presses the reference azimuth setting switch 2c to rotate to sound whether or not the rotation operation of the desired rotation operation mode has been completed at the end of the rotation operation. Can be confirmed. Therefore, the user can immediately confirm whether an appropriate turn has been made by himself or herself when performing turn practice such as dancing.
In addition, although it was determined whether the rotation operation was successful or unsuccessful based on the rotation time and the rotation speed of the rotation condition, it may be determined whether the rotation operation is faster or slower than the rotation time of the rotation condition. In this case, sound data corresponding to each determination result when the rotation operation is fast and slow may be stored, and the sound data may be output according to the determination result.

<Modification>
Although the embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and can be implemented in various other forms. For example, the above-described embodiment may be modified as follows to implement the present invention, or may be implemented in combination with each modification. Hereinafter, modifications of the present invention will be described.
(1) The embodiment described above is an example in which it is determined that the rotation is started when the rotation direction is changed from the reference direction and the detection of the rotation time is started. However, the acceleration is applied to the casing 2a of the rotation detection belt 2. A sensor may be provided to detect the start and end of the rotation operation according to the acceleration output from the acceleration sensor, and to measure the rotation time between them. In this case, the rotation detection belt 2 transmits information on the acceleration detected by the acceleration sensor together with the rotation direction information to the rotation analysis device 3. Then, in the rotation analysis device 3, for example, the detection of the rotation time is started when the rotation operation is started when an acceleration of a predetermined value or more is received, and the rotation analysis device 3 starts the detection of the rotation time. The detection of the rotation time may be terminated assuming that the rotation operation is completed when the acceleration is received.
In the above case, the rotation direction when the acceleration of a predetermined value or more is received may be automatically reset as the reference direction. In addition, when the rotational azimuth when an acceleration of a predetermined value or more is received is different from the reference azimuth, the rotational speed may be automatically detected using the rotational azimuth as the rotation start position. Further, the start of rotation may be determined by determining whether or not the acceleration at the start of rotation is greater than or equal to a threshold value greater than the predetermined value, that is, whether or not the initial speed of rotation is sufficient.

(2) The embodiment described above is an example in which the detection of the rotation time is started when the rotation direction is changed from the reference direction and the start of the rotation is determined. Thus, detection of the rotation time may be started. In this case, the rotation detection belt 2 is provided with a switch for instructing the start of detection of the rotation time. When the user presses the switch before the rotation operation, information indicating the start of detection of the rotation time is transmitted to the rotation analysis device 3. To start the rotation time detection. Alternatively, the detection of the rotation time may be started by another user operation via the operation unit 37 of the rotation analysis device 3.

(3) In the embodiment described above, the determination result of the rotation operation is output and then the sound corresponding to the determination result is output to notify the determination result. However, a predetermined musical sound is reproduced before the determination of the rotation operation. The volume of the musical sound being reproduced may be changed according to the rotation determination result. In this case, the rotation analysis device 3 stores the musical sound data to be reproduced and the volume control information for instructing the volume according to the determination result. For example, if the rotation operation is successful, the rotation operation is determined according to the volume control information. Sometimes, the musical sound may be reproduced with a volume larger than the default volume, and if the rotation operation fails, the music may be reproduced with a volume smaller than the default volume according to the volume control information.
Further, when a predetermined musical sound is reproduced during the rotation operation and it is determined that the rotation has failed, the tempo of the musical sound may be changed according to the rotation speed. In this case, similar to the above, the musical sound data to be reproduced, the rotation condition that defines the rotation speed of each rotation operation, and the tempo control information that defines the tempo clock speed when the rotation speed is faster and slower than the rotation speed of the rotation condition are stored. To do. Then, the rotation operation is determined in the same manner as in the embodiment, the rotation speed of the rotation operation is calculated, and when the rotation operation is determined to be unsuccessful, the rotation speed of the rotation condition is compared with the calculated rotation speed. . As a result of the comparison, for example, if the calculated rotation speed is fast, the music is played with the tempo clock speed increased according to the tempo control information, and if the calculated rotation speed is slow, the music is played with the tempo clock speed decreased according to the tempo control information. To do.

(4) In the above-described embodiment, when the detected rotation number is not the rotation number stored in the rotation condition information 320, or when the detected rotation time is not within the rotation time of the rotation condition information 320, the rotation operation is performed. Although it was an example of outputting a sound indicating failure, depending on the difference between the rotation condition and the rotation time stored in the rotation condition information 320 and the detection result when it is determined that the rotation operation has failed. It is also possible to output a sound and notify the difference from the rotation condition by sound. For example, audio data for each rotation speed different from the sound to be notified as a rotation operation determination result is stored, and when a rotation speed that does not satisfy the rotation speed defined by the rotation condition is detected, the detected rotation speed is handled. Audio data may be played back when detected.

(5) In the above-described embodiment, an example in which a sound indicating the determination result of the rotation operation is notified, but the present invention is not limited to this as long as the information indicating the determination result is notified. For example, the rotation detection belt 2 may be provided with a light emitting means such as an LED or a vibration means such as a vibrator, and the light may be emitted or vibrated according to the determination result of the rotation operation. In this case, when the rotation analysis device 3 determines that the rotation operation has succeeded or failed, information indicating the determination result is transmitted to the rotation detection belt 2, and the rotation detection belt 2 emits light according to the determination result. Or vibrate. In addition to notifying the determination result of the rotation operation by the above method, information indicating the determination result on the display unit 36 of the rotation analysis device 3, the rotation speed based on the rotation speed, the rotation time, the rotation speed, and the rotation time, the reference orientation Analysis information related to a rotation operation such as a rotation direction based on the rotation direction may be displayed.

(6) In the above-described embodiment, it has been described that the sound is output in either case of the success or failure of the rotation operation. For example, the sound is output only in one of the cases, and vice versa. Audio output may not be performed.

(7) In the above-described embodiment, the result of determining the rotation operation based on the rotation speed and the rotation time is an example. However, based on the rotation direction output from the three-axis magnetic sensor 2d at the start of the rotation operation. The elevation angle with respect to the horizontal plane on which the rotation operation is performed may be obtained, and the rotation operation may be determined using the elevation angle. In this case, a conversion table for converting a voltage value indicating a magnetic field into an azimuth and an elevation angle, and an elevation angle condition for each predetermined time in the rotation time of each rotation operation mode are set as rotation conditions for each rotation operation mode. Keep it. This elevation angle condition may be set by associating the elevation angle of each time within the rotation time, or may associate the elevation angle range at each time. Then, the rotation analysis device 3 sequentially receives the rotation azimuth from the rotation detection start time from the rotation detection belt 2 to obtain the elevation angle for every fixed time during the rotation operation, and compares it with the elevation angle condition defined in the rotation condition. . When the elevation angle is set as the elevation angle condition, the difference between the elevation angle based on the rotation azimuth information sequentially received during the rotation operation and the elevation angle set at the elevation angle condition is a predetermined value. After determining for all the elevation angles during the rotation time, if the elevation angle during the rotation operation satisfies the conditions such as satisfying the elevation angle condition more than a predetermined number of times, It may be determined that the rotation operation is successful.

(8) The above-described embodiment is an example in which the rotation detection belt 2 is attached to one user and the rotation operation is analyzed. However, the rotation detection belt 2 is attached to a plurality of users, and a plurality of users can simultaneously perform the analysis. You may make it analyze whether each rotation operation at the time of performing rotation operation satisfy | fills the conditions of the preset rotation operation aspect. For example, an example in which a plurality of users simultaneously rotate at the same rotation speed by a predetermined number of rotations as a condition of the rotation operation mode will be described below. In this case, a sound indicating the start of the rotation operation is output from the rotation analysis device 3, and each user performs the rotation operation simultaneously with the sound as a cue. In the rotation analysis device 3, the ID number of the rotation detection belt 2 of each user is set in advance, and the reference orientation information transmitted from each rotation detection belt 2 is stored for each ID number. Time information is stored in association with rotation direction information sequentially transmitted from the rotation detection belt 2. The rotation analysis device 3 detects the number of rotations based on the rotation direction information of each rotation detection belt 2, calculates each rotation speed of each user based on the number of rotations and the rotation time of each rotation operation, and calculates each calculated Compare the rotational speeds. For example, if the calculated difference between the minimum value and the maximum value of the rotation speed of each user is within a predetermined value range, it is determined that the rotation operation of all users is performed at the same rotation speed, and the determination result is shown. You may comprise so that audio | voice data may be output.

  Further, when the rotation operation condition is that all users rotate at a predetermined rotation speed at the same time, the rotation analysis device 3 sets the predetermined rotation speed as a rotation condition in advance, and the same as described above. The rotation speed of each user is calculated. Then, for each user's rotation speed, it is determined whether the rotation speed is within a predetermined value range from the predetermined rotation speed. If all the users are within the predetermined value range, it indicates that the rotation condition is satisfied. Audio data may be output. Further, the determination result of the rotation speed of each user may be notified by outputting voice data set in advance for each ID number of the rotation detection belt 2. As a result, it is possible to determine whether or not the rotation operations of a plurality of users as a whole satisfy the rotation conditions, and whether or not the rotation operations of individual users satisfy the rotation conditions.

  In addition, when each user performs a plurality of coordinated rotation operations by sequentially performing a rotation operation at a predetermined timing, the rotation analysis device 3 uses each ID number of the rotation detection belt 2 of each user. The rotation conditions such as the rotation timing and the start timing of rotation operation (elapsed time from the start time of the immediately preceding rotation operation, etc. determined in advance based on the rotation operation order) and the rotation speed are set in advance. Then, similarly to the embodiment, it is determined whether or not the rotation direction transmitted from each rotation detection belt 2 and the time information associated with the rotation direction satisfy the rotation conditions corresponding to the rotation detection belt 2. By doing so, the determination result about each rotation operation may be notified by voice.

(9) The embodiment described above is an example in which the determination of the rotation operation mode selected by the user is performed, but the rotation operation (operation condition) set in advance at a predetermined timing in the music while playing the music. You may make it perform determination of. Hereinafter, an example of this case will be described. FIG. 9A shows, as a movement locus 420a, an operation that the user should perform between the timings t1 to t4 with respect to the music reproduction time axis t. In this example, the user stands in the direction of arrow D at the timing of t1 (hereinafter, the direction of the front of the user is indicated by arrow D), and the operation performed between each timing of t1 to t4 is t1 to t2. During this time, the user moves counterclockwise to the position indicated by t2 (revolution) while rotating 90 ° (rotation) to the left side of the user (revolution). It moves to the position shown at t3, and during the period from t3 to t4, it rotates 2.5 times clockwise from the left side of the user while keeping the direction at t3 constant (revolution). When these operations are appropriately performed, the movement to each position indicated by a black circle a is performed at each timing t1 to t4.

The rotation analysis apparatus 3 includes music data including timing data indicating the timings described above, and motion information 400 (FIG. 9B) that defines a rotation amount as a motion condition of a rotational motion to be performed at each timing of the music. Is stored, and it is determined whether or not a series of user actions in accordance with the reproduction of the music data satisfies the operation condition of the operation information 400. In this case, the user wearing the rotation detection belt 2 depresses the reference azimuth setting switch 2c to set the reference azimuth, and the rotation analyzer 3 detects the music reproduction instruction and operation time by another user. In response to an operation for instructing the start, the reproduction of the music and the measurement of the operation time are started.
The rotation analysis device 3 detects the azimuth change at each timing of the music based on the timing data included in the music and the rotation direction information transmitted from the rotation detection belt 2 and records the detection result together with each timing. FIG. 9C shows a data example of the detection result information 410 in which the detection result is recorded.

  FIG. 9D shows a display example of an image 420 showing the movement locus of the user A in FIG. 9C, and a broken line 420b shows the movement locus of the user A based on the detection result information 410. b shows the position of the user A at each timing. The solid line 420a indicates the movement locus that the user should originally move, as in FIG. 9A, and the black circle a indicates the position that the user A should reach at each timing, as in FIG. 9A. 9B and 9C, the user A moves to the position indicated by t2 counterclockwise (revolution) while rotating (rotating) by 70 ° from the reference direction to the left side of the user A between t1 and t2. From t2 to t3, it moves to the position indicated by t3 in the forward direction of the user A without rotating while maintaining the direction rotated by 70 ° at t2, and the direction at t3 is kept constant between t3 and t4. It can be recognized that the user A has moved 1.5 times clockwise from the left side and moved to the position indicated by t4. Thus, by recording the azimuth change at the timing of music for each user and displaying the recorded data on the display unit 36, it is possible to check which user is not in time with the timing. Further, at each timing, it is determined whether or not the prescribed operation is performed by comparing the operation information and the detection result, and the determination result of each user is scored based on the evaluation score set in advance for the determination result. And may be displayed together with the recording result.

(10) The above-described embodiment is an example in which the rotation detection belt 2 is attached to the user's waist and the rotation operation is detected. For example, a person or an object serving as the axis of the rotation operation, such as a figure skating shoe. A rotation detection device having the same function as that of the rotation detection belt 2 may be attached to this portion.

(11) In the above-described embodiment, the personal computer is used as the rotation analysis device. However, a portable music player, a portable information device such as a mobile phone, a game machine, and the like are configured to have the function of the rotation analysis device. Also good.

(12) The above-described embodiment is an example in which the rotation detection belt 2 transmits the result of detecting the azimuth to the rotation analysis device 3, the rotation analysis device 3 determines the rotation operation, and notifies the determination result. The rotation detection belt 2 may be configured to have each function of the rotation analysis device 3.

(13) Although the above-described embodiment is an example of analyzing a user's rotational motion, the control unit 20, the orientation detection unit 22, and the communication unit 23 are provided in an object (such as a ball), and the rotation analysis device 3 , Storing movement mode information that predetermines the rotation direction (orientation) and movement direction of the object, sequentially compares the movement mode information and the rotation direction and movement direction of the object detected as described above, and notifies according to the comparison result May be performed. Further, the moving direction of the rotating object may be analyzed and the moving direction may be notified.
For example, the azimuth detecting unit 22 and the communication unit 23 are provided in a balance ball used for training the sense of balance of the body. In the rotation analysis device 3, each angle amount of a predetermined pitch angle and roll angle is set as a rotation condition for determining the rotation operation of the balance ball. In addition, the rotation analysis device 3 is configured to be able to transmit an instruction to output reference azimuth information to the balance ball, and the instruction is transmitted when the user gets on the balance ball. In such a configuration, the reference azimuth information is output from the balance ball, and the pitch angle and the roll angle at the time of setting the reference azimuth are set as the reference pitch angle and the reference roll angle. , The rotation analysis device 3 determines that the change amount of the pitch angle and the roll angle from the reference pitch angle and the reference roll angle is based on the output rotation direction information, the reference pitch angle and the reference roll angle. It is determined whether the angle amount is equal to or greater than the angle amount. When the pitch angle is equal to or greater than the angle amount of the rotation condition, a sound indicating that the pitch angle has been rotated is notified, and when the roll angle is equal to or greater than the angle amount of the rotation condition, the sound is rotated in the roll angle direction. A sound indicating this is notified. Further, when both the pitch angle and the roll angle satisfy the rotation condition, a sound indicating that the pitch angle and the roll angle are rotated is notified.

  Further, for example, the azimuth detecting unit 22 and the communication unit 23 may be provided in a ball about the size of a baseball, and a sound may be output according to the rotation direction when the ball is thrown. That is, a three-axis acceleration sensor is provided in the ball, and azimuth information and acceleration are sequentially transmitted from the ball to the rotation analysis device 3. In the rotation analysis device 3, the acceleration after removing the gravitational acceleration component from the acceleration is combined to generate a combined vector. As the reference azimuth, the azimuth when the value of the combined vector is 0 (when the user holds the hand and faces the front) is set. Then, the rotation direction information sequentially received from the ball and the reference direction are compared, and it is determined whether or not the azimuth angle from the reference direction of the rotation direction is increasing or decreasing, and the rotation direction is specified. To play preset audio data.

  Also, for example, in the case of outputting a sound according to the moving direction of the rotating ball and informing, as in the above case, the user temporarily holds the ball by holding it in his hand and the resultant acceleration vector The azimuth when the value is 0 is initially set as a reference azimuth. Then, the azimuth detection unit 22 in the ball outputs the azimuth information and the acceleration to the rotation analysis device 3. In the rotation analysis device 3, when the acceleration output from the ball is a predetermined value or more, the reference azimuth and the acceleration Based on the azimuth information at the time of output, a change in azimuth in which the ball has moved with respect to the reference azimuth may be detected, and sound may be generated based on voice data preset for each azimuth.

(14) In the above-described embodiment, in order to determine whether or not the preset rotation operation mode is successful, the number of rotations and the rotation time for each rotation operation mode are stored in advance as rotation conditions, and the rotation operation is performed. Although the example of determining the success or failure of the rotation operation based on the rotation condition at the time of completion and notifying the determination result has been described, a time-series rotation condition representing the rotation condition for each fixed time in the rotation time of each rotation operation mode is set Then, the time-series rotation direction information sequentially output from the rotation detection belt 2 from the start to the end of the rotation operation is compared with the time-series rotation condition, and the rotation operation at each timing according to the time-series rotation condition is determined. Whether or not this is done may be performed during the rotation operation.
As the time-series rotation condition, in addition to the rotation speed and the rotation time, for example, a rotation speed (angular speed), an azimuth change within a predetermined time from the start of rotation, and the like may be set. When the rotation detecting device is provided in the figure skating shoe as in the modification (10), the success or failure of the jump operation of the triple accelerator or the like is determined at the start of the rotation operation or during the rotation operation. The success or failure of the rotation operation may be predicted before the end of the rotation operation.

(15) In the above-described embodiment, the example of determining the success or failure of the rotation (spinning) operation has been described, but in addition to the determination of the success or failure of the rotation (spinning) operation, the accuracy of the rotating shaft during the rotation (spinning) operation Or the stability may be determined. In this case, the z-axis of the geomagnetic sensor is used as the rotation axis, and the inclination (roll angle, pitch angle) of the z-axis with respect to the x-axis and y-axis of the geomagnetic sensor is detected from the azimuth information output from the geomagnetic sensor. Further, the inclination of the rotation axis may be detected by using a triaxial acceleration sensor in combination and detecting the direction of gravity acceleration (vertical direction). And, for example, as a determination condition that the rotation axis is accurate, as a determination condition that the inclination (roll angle, pitch angle) of the rotation axis with respect to the vertical direction is within a predetermined value range, or that the rotation axis is stable Pre-set conditions such as maintaining a constant rotation axis tilt (roll angle, pitch angle) for a predetermined time or more within the rotation time, and determining the rotation axis inclination detected during the rotation operation as described above It is determined whether the condition is satisfied, and a sound indicating the determination result is notified during the rotation operation or after the rotation operation is completed.

(16) In the above-described embodiment, the example in which the rotation analysis device 3 includes the rotation time detection unit 31 has been described, but the rotation detection belt 2 may be provided with the rotation time detection unit 31. In this case, the time information measured by the rotation time detection unit 31 when the rotation direction information is output by the direction detection unit 22 is transmitted to the rotation analysis device 3 in association with the rotation direction information. .
