Embodiment 1

[0035] figure 1 It is a flow chart of a method for monitoring exercise status using a wearable device according to an embodiment of the present invention, see figure 1 , the wearable device is provided with a sensor, and the method includes the following steps:

[0036] Step S101, when a monitoring process starts, control the sensor to collect the user's motion data;

[0037] Step S102, extracting one or more feature quantities used to identify the user's exercise state from the exercise data to obtain test data;

[0038] Step S103: Match the test data with the stored template data representing the predetermined motion state to obtain template data that successfully matches the test data, and determine that the motion state corresponding to the template data associated with the matched test data occurs.

[0039] The above steps S101 to S103 may be implemented by functional modules provided in the wearable device.

[0040] Depend on figure 1From the method shown, it can be ...

Embodiment 2

[0047] figure 2 It is a flow chart of a method for monitoring exercise status using a wearable device according to another embodiment of the present invention, see figure 2 , the overall flow of the method of using wearable devices to monitor the state of exercise is as follows: firstly, the four basic swimming postures are recognized, and at the same time, the occurrence of reentry movements can also be recognized. It mainly adopts motion state monitoring and recognition based on time-domain features and support vector machine (SVM). Secondly, for the three-axis acceleration data collected during swimming, the sliding window processing method is adopted, and there must be a certain overlap between adjacent sliding windows. For the X, Y, Z three-axis acceleration data in the sliding window, the sliding mean filter is used to remove the influence of noise and obtain relatively smooth data. Then, in each sliding window, temporal features are extracted separately. Finally, s...

Embodiment 3

[0087] The method of using the smart watch to monitor the state of swimming in this embodiment specifically includes the following steps:

[0088] Step 31, the sensor collects data

[0089] The built-in acceleration sensor of the smart watch is used, and the collected data is the X, Y, and Z three-axis acceleration of the swimming action. The collected data are respectively stored in the ring buffer (ring buffer) whose length is Len, such as image 3 shown.

[0090] Step 32, sliding window processing.

[0091] Add sliding windows to the three-axis acceleration data taken from the ring buffer, such as Figure 4 shown. The size of each window is N samples, the covered time length is T seconds, and the moving step of the sliding window is step samples (step size=N / 2 can be taken, that is, adjacent windows overlap by half the window length). Subsequently, filter processing is performed on the data of each window.

[0092] The purpose of sliding window processing: sliding win...

Abstract

The invention discloses a wearable device and a method adopting the same to monitor a motion state. A sensor is arranged in the wearable device. The method comprises steps as follows: controlling the sensor to acquire motion data of a user when a monitoring process starts; extracting one or more characteristic values for identifying the motion state of the user from the motion data to obtain test data; matching the test data with stored template data representing a predetermined motion state to obtain template data matched with the test data successfully, and determining occurrence of the motion state corresponding to the matched template data associated with the test data. According to the technical scheme of the embodiment, the motion state of a wearer is monitored through the wearable device, due to the wearable characteristic of the wearable device, the motion state can be monitored and identified at any time in a movement process when the user wears the wearable device, the user knows own motion state conveniently, the motion effect is improved, and the user experience of the wearable device is improved.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a wearable device and a method for monitoring exercise status by using the same. Background technique [0002] Traditionally, the monitoring and tracking of the athlete's movement state (for example, swimming state) is mainly carried out visually, and analysis and recognition are performed based on video data afterwards. This scheme cannot provide statistical recognition results in real time; in addition, there are also Some professional sports monitoring equipment can analyze sports data such as swimming posture and exercise volume, but they are expensive and inconvenient to carry, so they are not suitable for ordinary swimming enthusiasts. Moreover, the accuracy of the exercise state monitoring results obtained by the existing exercise state monitoring scheme also needs to be improved. Contents of the invention [0003] The present invention provides a wearable devi...
