On one hand, the wearable devices aiming at exercise, health and health tracking have great development potential, and on the other hand, the characteristics of the VR devices, such as scenarization, enjoyment, data tracking specialty and convenience, can attract users with exercise needs. During exercise of the user, the energy consumption data is the basic index of the exercise effect, the expression of the core data of the exercise effect of the user, and the exercise index that users are most concerned about. At present, the energy consumption of exercise is estimated by using related data on the head-mounted display and the handle.

Referring to
S201, acquiring the exercise data of a user in a preset time period and the physical parameter preset by the user.
The exercise data includes exercise data of a head, hands and legs of the user.
In the present disclosure, by collecting exercise data of the head, the hands, and the legs, the collected exercise data of the user can be made more complete, and based thereon, the determination of the energy consumed by the user is made more accurate.
Further, the physical parameter preset by the user include: height, weight and so on. For different users, when the height and the weight are different, the energy consumed even though performing the same exercise is different, so when the energy consumed by the user is determined, the accuracy of determining the consumed energy can be improved by considering the physical parameter preset by the user.
In the present disclosure, the physical parameter of the user is acquired and utilized at the user's consent.

In summary, the data processing method and device provided by the embodiment are applied to a wearable devices and include the following steps: acquiring exercise data of a user in a preset time period and a physical parameter preset by the user, wherein the exercise data includes exercise data of a head, a hand and a leg of the user; and inputting the exercise data and the physical parameter into a pre-trained energy determination model for processing to obtain energy consumed by the user in the preset time period. The present disclosure, based on the exercise data acquired from the head, the hand and the leg of the user, realizes the comprehensive collection of the exercise data, and the energy consumed by the user in the exercise process can be determined accurately in real time by determining the energy consumption through the pre-trained energy determination model.
Referring to
S301, acquiring the training sample and the label data corresponding to the training sample.
The training samples are exercise data serving as samples, and the label data are exercise coefficients corresponding to the training samples.
In the present disclosure, a plurality of training samples are included, each training sample including a set of exercise data, for example: the moving distance x1 of the head-mounted display, the square x2 of the average linear velocity, the square x3 of the average angular velocity, the total moving distance x4 of the handle, the average linear velocity x5, the average angular velocity x6, the square x of the average angular velocity and the square x8 of the average acceleration of the leg tracking device, and the tag data y are the numerical values greater than 1.
S302, inputting the training samples into a multivariate linear regression submodel for processing to obtain a predicted exercise coefficient.
The mathematical expression of the multivariate linear regression submodel is N=WTX, wherein W is a model parameter of the multivariate linear regression submodel, W={α1, α2, α3, α4, . . . , αn}, X={x1, x2, x3, x4, . . . , xn}, wherein n is a positive integer greater than 1 and is specifically the number of exercise data in a set of exercise data, and as shown above, includes eight exercise data.
Specifically, W is set as an initial default value, a set of exercise data is applied to the formula N=WTx to obtain a predicted exercise coefficient N1.
S303, adjusting the model parameter of the multivariate linear regression submodel based on the predicted exercise coefficient and the loss value of the label data to obtain the trained multivariate linear regression submodel.
The calculation formula of the loss value is as follows: S=∥y−WTX∥22+λ∥W∥22. λ is the coefficient for preventing over-fitting.
In addition, if the loss value S is larger than the threshold value for the loss value, the loss value is adopted to adjust the model parameter W, then the set of exercise data is continuously adopted to train the multiple linear regression submodel until S is smaller than the threshold value of the loss value, then the next set of exercise data is continuously adopted to carry out the training, and the model parameter with the smallest ΣS is selected as the model parameter of the trained multiple linear regression submodel.
Further, the model parameter of the multiple linear regression submodel is greater than 0, specifically, the constraint αi is greater than 0, wherein i is 1 to n.
In addition, during the training process, the optimal model parameter can be selected by adopting a cross validation method. Specifically, a plurality of data samples are included, and the plurality of data samples are divided into m parts. Then m−1 parts (there are m ways to choose) of the data samples are selected as the training samples to carry out the training, m model parameters are correspondingly obtained, then the rest data sample are used as verification samples to determine the optimal model parameters of the m model parameters, and the optimal model parameters are used as the final model parameters of the multiple linear regression submodel for online use.
Illustratively, 60 training samples are included and divided into 3 parts, namely a first set of data sample (20 training samples), a second set of data sample (20 training samples) and a third set of data sample (20 training samples). Firstly, a multivariate linear regression submodel is trained by adopting a first set of data sample and a second set of data sample to obtain a model parameter A, and then the model parameter A is verified by adopting a third data sample to obtain a verification result a. Then, the multivariate linear regression submodel is trained by adopting the first set of data sample and the third set of data sample to obtain a model parameter B, and then the model parameter B is verified by adopting the second set of data sample to obtain a verification result b. Then, the multivariate linear regression submodel is trained by adopting the second set of data sample and the third set of data sample to obtain a model parameter C, and then the model parameter C is verified by adopting the second set of data sample to obtain a verification result c. If the best verification result among the verification results a, b, and C is the verification result c, the model parameter C can be determined as the final model parameter of the multivariate linear regression submodel.
In the present disclosure, the verification result can employ a formula
Radj2 represents the verification result, namely the determination coefficient for correction, and is used for representing the fitting degree of the multivariate linear regression submodel. The larger the fitting degree of the multivariate linear regression submodel is, the higher the fitting degree of the multivariate linear regression submodel is. N represents the number of verification samples, for example, 20 as described above, and K represents the number of variables in the exercise data, for example, 8 variables as described above. R is a determination coefficient, and is also used to indicate the fitting degree of the model, and the specific determination method is not limited herein.

In the present disclosure, the inertial measurement data is acquired by a wearable device of a user. The inertial measurement data includes: linear acceleration and angular acceleration.

In the present disclosure, it is also necessary to unify the units of the exercise data. For example, if the moving distance of the head-mounted display in a preset time (3000 ms) is L1 (cm), the moving distance may be unified as how many centimeters are moved per minute, and the moving distance is (L1/3000)×1000×60. Other exercise data may also be unified into data in units of minutes for time and centimeters for distance.

In the present disclosure, the physical parameter includes: age, gender, height and weight. The basal metabolic rate can be expressed by Harris-Benedict equation. The equation is as follows:
From the above, the basal metabolic rate for one day can be obtained, and further, the basal metabolic rate per minute can be calculated as D=C/1440.
S308, determining the energy consumed by the user in a preset time period based on the exercise coefficient and the basal metabolic rate.
The energy consumed by the user per minute can be obtained by the product of the exercise coefficient and the basal metabolic rate. In the present disclosure, it is necessary to determine the consumed energy J of the user within a preset time T. J=N×D×T/60. N represents the exercise coefficient per minute.
