In summary of the above technical features, the main effects of the exercise assisting method, exercise assisting module and wearing aids of the present invention will be clearly presented in the following embodiments.

Please refer to the first figure, which discloses an exercise assisting module according to an embodiment of the present invention, including: at least one wearing aid (1) and at least one assisting device (2).

Continue to refer to the second figure, the aforementioned wearing aid (1) includes a wearing part (11), a signal transceiver module (13) connected to a control unit (12), at least one bone conductor (14), one The measurement subsystem (15) and a prompting subsystem (16). The wearing part (11) is, for example, swimming goggles, but it is not limited thereto, and may also be other wearing equipment such as swimming caps. Preferably, the power supply unit of the aforementioned wearing aid (1) can provide a wireless charging function. The aforementioned bone conductors (14) are two in this embodiment to correspond to the left and right ears, respectively.

Continue to see the second figure. The signal transceiver module (13) is used to send a sending signal and a corresponding return signal to the auxiliary device (2) one by one for the measurement subsystem (15). The ranging module (151) calculates a distance value based on time difference information between the sent signal and the return signal. In detail, the aforementioned sending signal and the aforementioned return signal can be sent successively through electromagnetic waves, and both the aforementioned sending signal and the echo signal include a time stamp for the ranging module (151) to calculate the time difference by the time stamp. The distance value is obtained in conjunction with the transmission speed of electromagnetic waves in the air. Therefore, if the auxiliary device (2) is set on the shore of the swimming pool along the center extension line, it can still provide a one-dimensional distance value prompt. A position prompting module (161) of the prompting subsystem (16) generates a position prompting message through the vibration of the aforementioned bone conductor (14). However, if you want to locate in space, you need more ranging points, so it is better to use at least three of the aforementioned auxiliary devices (2), you can use the triangle positioning method to integrate the three aforementioned auxiliary devices ( 2) Establishing a rectangular coordinate system. Since this embodiment is applied to swimming gear, in addition to setting the relative position of obstacles and the like in the coordinate system, environmental data such as water channel width, pool length, and depth can also be set. In this way, swimming auxiliary prompt functions such as water channel end prompt, swimming speed prompt, water rope collision prompt, and wall contact prompt can be provided. Preferably, the aforementioned wearing aids (1) are plural; the prompting subsystem (16) further includes a collision prompting module (162), and the collision prompting module (162) is used to compare the wearing assisting devices (162). 1) The distance value of each other.

Continue to refer to the second figure. The measurement subsystem (15) also includes a physiological signal sensing module (152). The physiological signal sensing module (152) is used to obtain a physiological characteristic value. For example, the physiological signal sensing module (152) may be a blood oximeter, but since a general optical pulse oximeter needs to emit and receive red light on opposite sides in order to collect signals normally, and It is necessary to choose a thin tissue layer, so when applied to swimming goggles and the wearing position is above the ear, it is difficult to achieve such conditions. Therefore, when applied to swimming goggles, a reflective oximeter is used to receive the reflection of light. Rate and based on photoplethysmography (PPG), by measuring changes in blood flow at specific locations, the pulse frequency can be obtained periodically from the signal under test, and changes in blood oxygen concentration can be measured (normal value is about 0.99, but (Concentration decreases steadily during belching, and then rises slowly after rebreathing).

In detail, the attitude angle sensing module (153) is an inertial measurement unit (IMU). The inertial measurement unit is mounted on the wearing part (11). The inertial measurement unit includes a gyroscope and An accelerometer (such as a piezoelectric accelerometer). In this embodiment, the wearing part (11) is a swimming goggle, and obtains the angular velocity and acceleration of the user's head in a three-degree space to calculate the attitude angle information, so as to know whether there is improper limb movement, and The frequency of the angle change can also be used to help estimate the number of ventilations for the user. Taking freestyle as an example to further explain, freestyle beginners often mistakenly believe that the main reason for failure of ventilation is because the head is not raised high enough, so they deliberately raise their heads and use a very exaggerated posture to raise their heads for ventilation. The shaft has an excessively large angle change, which causes the user's body to sink due to the reaction force. Therefore, when the angle has an excessively large angle change compared to the preset value, the gesture prompting module (164) can promptly remind the user through the aforementioned bone conductor (14), so that the user can correct the posture in real time and continuously correct.

The screen can also be a touch screen, so as to click on the marking pattern corresponding to each wearing aid (1) and call a specific or all wearing aids (1). In detail, each wearing aid (1) has an identification number, and each identification number corresponds to the aforementioned marking pattern.

Then the user can start swimming, and the exercise assisting module provides the exercise assisting method.

The exercise assisting method mainly includes a position prompting program and a physiological signal monitoring program. Continue to refer to the tenth and eleventh figures and the second figure. The position prompting procedure is to first let the signal transmitting and receiving module (13) of the wearing aid (1) and the aforementioned auxiliary device (2) one after the other. Send a sending signal and a corresponding return signal for a ranging module (151) to calculate a distance value based on the time difference information of the sending signal and the return signal, and then a position prompting module (161) According to the distance value, the bone conductor (14) is vibrated to generate the position prompt message.
