The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the singular forms "a", "an" and "the" include plural references

[0051] Referring to Figure 1 The first embodiment of the present application provides a motion state interaction method of a smart watch, comprising the following steps:

[0052] S10: obtaining state information of a user, determining whether the user enters a motion state based on the state information, and if the user enters the motion state, connecting the smart watch to a Bluetooth earphone in communication;

[0053] The state information comprises a three-axis acceleration signal and a second heart rate signal. It can be understood that an inertial measurement unit and an optical heart rate sensor are arranged in the smart watch, the three-axis acceleration signal is obtained by the inertial measurement unit, and a photoplethysmography signal is collected by the optical heart rate sensor. After signal processing of the photoplethysmography signal, the second heart rate signal is formed. In this embodiment, the motion state is a running motion.

[0054] The step S10 comprises:

[0055] S110: obtaining an acceleration modulus value from the three-axis acceleration signal, and obtaining an acceleration variance from the acceleration modulus value;

[0056] The formula for obtaining the acceleration modulus value is:

[0057]

[0058] wherein a tm represents the acceleration module value at time t, a xt , a yt , a zt respectively represent the three-axis acceleration at time t;

[0059] The acceleration variance is obtained by the following formula:

[0060]

[0061] wherein δ a represents the acceleration variance, N represents the total number of acceleration module values within the time window, a im represents the acceleration module value at time i, and a im ∈N, μ represents the mean value of the acceleration module values within the time window.

[0062] S120: obtaining the heart rate variation amplitude of the second heart rate signal, comparing the acceleration variance with a fluctuation threshold, and comparing the heart rate variation amplitude with a variation threshold;

[0063] It can be understood that the second heart rate signal at different times is subjected to difference processing, and the heart rate variation amplitude can be obtained.

[0064] S130: if the acceleration variance is greater than the fluctuation threshold and the heart rate variation amplitude is less than the variation threshold, determining that the user enters a motion state;

[0065] When the user enters the motion state, the smart watch searches whether there is an accessible Bluetooth device within a preset range, if there are several accessible Bluetooth devices within the preset range, the device model of the accessible Bluetooth device is obtained, the device type of the accessible Bluetooth device is obtained based on the device model, the device type is a Bluetooth headset, a Bluetooth sound box, etc., and when there is a Bluetooth headset, the smart watch is communicatively connected to the Bluetooth headset.

[0066] Preferably, the method further comprises:

[0067] S20: obtaining the location information of the user, determining whether the user is in an outdoor state through the location information; if the user is in an outdoor state, obtaining weather information and air quality information, generating an outdoor recommended exercise plan based on the location information, the weather information and the air quality information, and playing the outdoor recommended exercise plan through the Bluetooth headset;

[0068] When the user is running, if the user is in an indoor state, it is determined that the user is running on an indoor treadmill, and the subsequent step S30 is directly entered. If the user is in an outdoor state, the nearest suitable running site is searched based on the position information, and an outdoor recommended exercise plan is generated in combination with the weather information and the air quality information. For example, if the weather is sunny and the air quality is good, the outdoor recommended exercise plan is: "It is recommended that you run 5 kilometers at XX location." Understandably, if the weather information indicates that it may rain later, the rain warning will be added to the outdoor recommended exercise plan, and the user is advised to shorten the exercise time or cancel the exercise.

[0069] S30: continuously acquiring a first heart rate signal of the user, acquiring a heart rate interval percentage based on the first heart rate signal, generating exercise interactive broadcast information according to the heart rate interval percentage, and broadcasting the exercise interactive broadcast information through the Bluetooth earphone;

[0070] The exercise interactive broadcast information includes first broadcast information, second broadcast information and third broadcast information,

[0071] Specifically, the step S30 includes:

[0072] S310: acquiring age information of the user, and acquiring a maximum heart rate signal based on the age information;

[0073] The formula for acquiring the maximum heart rate signal is:

[0074]

[0075] Wherein, H max represents the maximum heart rate signal, and Age represents the age information;

[0076] S320: acquiring a heart rate interval percentage through the maximum heart rate signal and the first heart rate signal, and comparing the heart rate interval percentage with a first threshold value and a second threshold value respectively;

[0077] The formula for acquiring the heart rate interval percentage is:

[0078]

[0079] Wherein, P t represents the heart rate interval percentage at time t, H t represents the first heart rate signal at time t;

[0080] The second threshold value is less than the first threshold value. In this embodiment, the second threshold value is 60%, and the first threshold value is 85%.

[0081] S330: generating the first broadcast information if the heart rate interval percentage is less than the second threshold value;

[0082] S340: generating the second broadcast information if the heart rate interval percentage is greater than the first threshold value;

[0083] For example, if the heart rate interval percentage is 50%, which is less than the second threshold value, the first broadcast information is: “Your heart rate is low, please speed up”; if the heart rate interval percentage is 87%, which is greater than the first threshold value, the second broadcast information is: “Warning, your heart rate is too high, please slow down immediately”.

[0084] Preferably, the step S30 further comprises:

[0085] S350: obtaining pace information of the user, and comparing the pace information with a speed threshold value; if the pace information is greater than the speed threshold value, the second broadcast information is modified into third broadcast information;

[0086] It can be understood that when running, if the user actively increases the pace, the heart rate will also increase. Therefore, by combining the pace information, it can be determined whether the user is in subjective high-intensity training when the heart rate is high. After determining that it is a subjective behavior of the user, the alarm will not be interrupted immediately. The third broadcast information is: “You are in the extreme intensity interval, please keep the rhythm and pay attention to your body state”, which avoids unnecessary interference when the user actively performs high-intensity interval training.

[0087] Preferably, in the step S30, the voice instruction of the user can also be received through the Bluetooth earphone, and normal motion interactive information including heart rate information, pace information, motion distance, etc. can be broadcast based on the voice instruction.

[0088] S40: determining whether the user exits the motion state based on the state information, and generating summary broadcast information if the user exits the motion state, and broadcasting the summary broadcast information through the Bluetooth earphone;

[0089] It can be understood that if the acceleration variance is less than the fluctuation threshold value and the heart rate change amplitude is less than the change threshold value, it is determined that the user exits the motion state. The summary broadcast information is formed based on the average heart rate, average pace, motion distance, etc. of the user in the motion state.

[0090] By acquiring the state information of the user, it is judged whether the user enters or exits the motion state based on the state information, so as to realize automatic identification of the motion state, and after entering the motion state, the connection between the smart watch and the Bluetooth earphone is automatically completed; after connecting the Bluetooth earphone, the first heart rate signal is continuously monitored, the first heart rate signal is taken as a reference to judge different motion conditions of the user in the motion state, and then the motion interaction broadcast information is generated based on different motion conditions, and the current motion condition of the user is informed in real time through the Bluetooth earphone, so that when the user is in the motion state, the user can adjust the body state in real time according to the motion interaction broadcast information, and dynamic interaction with the user is realized.
