That is, the travel detection unit outputs a timing signal indicating that the travel cycle has been detected each time the z-axis acceleration reaches a maximum value equal to or greater than a predetermined threshold value. In reality, the 3-axis acceleration detected by the inertial measurement unit contains high-frequency noise components, so the travel detection unit detects the travel cycle using the z-axis acceleration from which noise has been removed by passing through a low-pass filter. To do.

The data analysis means by the information analysis means (6) will be described in detail below.
(Reference data)
In order to generate the advice information, a predetermined reference data for comparison with the measured data during the exercise of the user (U) is required. For example, in the case of a marathon, the reference data is selected from the data of athletes such as top professionals who are participating in competitions such as the Olympic Games from the height, weight, and target time of the user.
Reference data is shown in FIG. 7A. According to FIG. 7A, it can be seen that the acceleration on the vertical axis is longer in the vicinity of zero G than in other movements, which indicates that both feet are floating in the air for a long time.
Also, from the graph of the gyro value, when the waveform of the gyro value (GY) in the vertical direction is a round mountain shape, it can be seen that the right foot of the user (U) is moving from the back to the front, and the gyro value in the vertical direction ( When the waveform of GY) is a round valley, it can be seen that the left foot of the user (U) is moving from the back to the front.
The predetermined reference data used in the exercise advisor system (1) according to the present invention includes ideal exercise information data to be targeted (for example, top professionals, business team athletes, etc.), and the user's own past exercise. Information data, exercise information data of other users other than the user (for example, coaches and advanced players in club activities), or a combination thereof, etc., but are not limited to this, and the level and goal of each user. It is possible to set the standard data according to.
A plurality of reference data can be set at one time. Therefore, for example, the advice information for approaching the ideal exercise is acquired from the difference from the ideal exercise information data to be targeted, and the user's own proficiency is obtained from the difference from the user's own past exercise information data. You can get advice information about the degree and condition.
The user (U) sets desired reference data in advance using the terminal device (3) or the like, and based on the difference between the reference data and the actually measured data, the information analysis means (6) provides advice information. Will be generated.

(Comparison of reference data and actual measurement data)
The difference between the desired reference data and the measured value obtained by the movement of the user (U) is obtained by calculation. As a result, it is possible to numerically indicate how superior or inferior the measured value is to the reference data. On the other hand, according to the user data of FIG. 7B, it is shown that the time when both feet are floating in the air is shorter than the graph of FIG. 7A described above.

(Data analysis based on the difference between standard data and measured data)
7A and 7B are diagrams showing an example of analysis data of exercise information measured by using the exercise advisor system according to the present invention. The data analysis based on the difference between the reference data and the measured data will be described in detail below.

(Generation of advice information based on data analysis)
Referring to FIG. 7B, the waveform (1) in the figure indicates the contact timing of the sole of the foot, and in the case of this user, sudden deceleration starts in the traveling direction.
The waveform (2) in the figure indicates that the grounded foot is the center of the body and begins to accelerate in the direction of travel, but the waist is subjected to maximum gravity in the vertical direction.
The waveform (3) in the figure indicates that it is just before kicking up the foot that is in contact with the ground, and gravity is applied to the waist again in the vertical direction.
The waveform (4) in the figure shows just before the foot leaves the ground, and the constant velocity movement starts from here.
The waveform (5) in the figure indicates that the vehicle is floating in the air, and because of the constant velocity moving state, the acceleration moves in a substantially constant state.
From the above waveforms (1) to (5), it can be seen that the impact of the left foot touching down and the change level of the propulsive force are small, and from this, it is inferred that there is a difference in the muscle strength of the left and right feet or the existence of a failure.
Furthermore, looking at the landing impact, the left foot is 5G, while the right foot is 6 to 8G, and the left and right balance is lost.
In this way, when it is presumed from the analysis data that the left-right balance is lost, the terminal device provides the user with advice information regarding the left-right balance.
When the user's exercise is completed, a comprehensive evaluation of the exercise by scoring is generated. For example, as an example of the evaluation method, it is possible to score from the values of the acceleration in the vertical direction (AY) and the acceleration in the traveling direction (AZ).

(Use of temperature / humidity sensor information in generating advice information)
A temperature / humidity sensor is used to grasp the sensible temperature, the ambient temperature, and the humidity, and to estimate the degree of fatigue of the user during exercise and the necessity of hydration.

(Use of barometric pressure sensor information in generating advice information)

(Use of geomagnetic sensor information in generating advice information)
Of the three axes (XYZ axes) of the earth as a sphere, a geomagnetic sensor is used to grasp the inclination of the user with respect to the Z axis.
By using the geomagnetic sensor, it is possible to more accurately grasp the posture of the user during exercise.

As mentioned above, the advice information includes the posture of the user (U), left-right balance, front-back balance, moment, stride / pitch, warning and correction of vertical movement of the center of gravity, and comprehensive evaluation of the movement by scoring. ..
This advice information may be a mechanical instruction or a trainer's instruction registered in advance (including manual instruction registration by the user).
As an example of a mechanical instruction, if it is determined by data analysis that the left-right balance is tilted to the left, an instruction to bring the center of gravity to the right side can be considered.
As an example of the trainer's instruction, if it is determined by the data analysis that the left-right balance is tilted to the left, an instruction to swing the right hand more strongly can be considered.
In this way, the user (U) can confirm the mechanical correction instruction, the instruction of the trainer registered in advance, or one of the instructions in real time, and select the correction instruction suitable for each user. Can be done.

The advice information transmitted to the terminal device (3) is displayed, for example, as shown in FIGS. 9 to 13. However, the display of the advice information shown in FIGS. 9 to 13 is an example, and any method may be used as long as the notification method can notify the user (U) of the advice information.

FIG. 11 is a diagram showing an example of a method of displaying advice information regarding the quality of the running state of the user (U) when traveling a long distance such as a full marathon.
In FIG. 11A, the evaluation value related to the form calculated from the traveling direction acceleration, the vertical direction acceleration, and the gyro value for each mileage is shown in a bar graph at the upper part. As shown in (c) of FIG. 11, the presence or absence of unnecessary moments is grasped from the acceleration signal at the time of landing and kicking, and the gyro signal to improve the running efficiency (make the posture that the moment due to the center of gravity is not generated during running). Can be made to. By comparing this evaluation value with a threshold value obtained from past cumulative data or reference data, it is possible to detect form disturbance and to detect fatigue from changes in the evaluation value due to time or mileage. Further, by displaying the advice information for correcting the exercise form or the like at the lower part of the screen, the user (U) can easily improve the exercise form or the like.
