The embodiment discloses a method for determining a user gesture, referring to fig. 1, including the following steps S110-S160:
referring first to fig. 2, the gesture monitoring apparatus according to the embodiment of the present application includes a wireless communication module 210, where the wireless communication module 210 is composed of a radio frequency module and a micro controller unit, and may implement a wireless communication function with a user device. The wireless communication module 210 may support any one or more of a variety of communication modes, such as Wi-Fi, bluetooth, zigBee and LoRaWAN. The user device may be an electronic device such as a mobile phone, tablet, wearable device, PC (Personal Computer ) or a background server running an application of a method for determining a user gesture.
The gesture monitoring apparatus further comprises a central control module 230, wherein the central control module 230 is preferably a programmable logic controller PLC, and adopts a programmable memory to store therein instructions for performing operations such as logic operation, sequential operation, timing, counting, arithmetic operation, etc., and can realize the function of controlling other circuit devices through digital or analog output.
The gesture monitoring device is connected with a stimulation module 220, the stimulation module 220 is connected with a central control module 230, the stimulation module 220 adjusts and controls parameters such as frequency, amplitude, waveform and the like of the electric signal through an adjusting circuit according to the received instructions, the electric signal is amplified through an output circuit and is output to the electrode, and the electrode is used for transmitting the electric signal to a target tissue or organ.
The stimulation module 220 further includes at least one stimulation electrode 221, a plurality of stimulation electrodes 221 are arranged in parallel, and the plurality of stimulation electrodes 221 are simultaneously connected with the stimulation module 220. The stimulation electrode 221 can be attached to the skin of the user or can be inserted inside the skin of the user, and the specific installation position of the stimulation electrode 221 needs to be determined based on parameters such as the height, weight, body fat rate, and the like of the user, which is not further limited in this embodiment. The central control module 230 of the gesture monitoring apparatus needs to control the stimulation module 220 to apply stimulation to the user when a preset condition is satisfied, where the preset condition may be a stimulation application time set on the user apparatus, or may be other manually set triggering conditions.
When the preset condition is met, the user equipment sends a starting instruction to the wireless communication module 210, the wireless communication module 210 receives the starting instruction and sends the starting instruction to the central control module 230, and after the central control module 230 receives the starting instruction, the central control module simultaneously sends a measuring instruction to a plurality of preset sensors, wherein the preset sensors are preferably piezoresistor sensors, and the piezoresistor sensors have the advantages of simple structure and low cost, have the advantages of high sensitivity and high precision, and are commonly used in the fields of medical detection, human body mechanics research and the like. The number of preset sensors is preferably four. The following is an illustration of the provision of four piezoresistive sensors. The four piezoresistive sensors include a first sensor 241, a second sensor 242, a third sensor 243, and a fourth sensor 244, respectively.
Referring to fig. 3, the first, second, third and fourth sensors 241, 242, 243 and 244 are disposed at four sides of a predetermined circuit board in a predetermined manner. The first sensor 241 is disposed at an upper end of the predetermined circuit board, the second sensor 242 is disposed at a lower end of the predetermined circuit board, the third sensor 243 is disposed at a left end of the predetermined circuit board, and the fourth sensor 244 is disposed at a right end of the predetermined circuit board. Referring to fig. 2, the first sensors 241 and the second sensors 242 are staggered such that the first sensors 241 and the second sensors 242 are not collinear, i.e., when the first sensors 241 are projected to opposite sides, a projected first sensor is obtained, and an area overlapping area cannot exist between the projected first sensors and the second sensors 242. The third sensor 243 and the fourth sensor 244 are staggered in accordance with the principle described above.
According to practical test experience, due to the integrated design of the four piezo-resistive sensors on the circuit board, when the two opposite sensors are not staggered, for example, when the first sensor 241 and the third sensor 243 are projected to overlap, the position information of the first sensor 241 and the position information of the second sensor 242 interfere with each other, which affects the judgment of the central control module 230 on the position information of the first sensor 241 and the position information of the second sensor 242. When the pressure value measured by the first sensor 241 is the same as the pressure value measured by the second sensor 242, the received pressure value is transmitted to the central control module 230, and the central control module 230 cannot determine the source of the received pressure value, so that the accuracy of the data is low. In particular, the accuracy of the data is lower when there are at least four preset sensors. The first sensor 241, the second sensor 242, the third sensor 243 and the fourth sensor 244 are arranged in the first preset mode, and the two opposite side preset sensors are arranged in a staggered mode, so that the problems can be effectively avoided, and the accuracy of data is improved.
S110, acquiring a first pressure difference value, wherein the first pressure difference value is a difference value between the first pressure value and the second pressure value.
S120, obtaining a second pressure difference value, wherein the second pressure difference value is a difference value between the third pressure value and the fourth pressure value.
After the central control module 230 simultaneously sends measurement instructions to the first sensor 241, the second sensor 242, the third sensor 243 and the fourth sensor 244, the first sensor 241 measures a first pressure value, the second sensor 242 measures a second pressure value, the third sensor 243 measures a third pressure value and the fourth sensor 244 measures a fourth pressure value. The four piezo-resistive sensors simultaneously convert the measured four pressure values into four sets of electrical signals, the first pressure value into a first electrical signal, the second pressure value into a second electrical signal, the third pressure value into a third electrical signal, the fourth pressure value into a fourth electrical signal, and the piezo-resistive sensors and transmit the electrical signals to the central control module 230 for processing.
The central control module 230 simultaneously transmits the first electrical signal, the second electrical signal, the third electrical signal and the fourth electrical signal to the user equipment, and the user equipment converts the corresponding electrical signals into the original pressure values after receiving the electrical signals, thereby obtaining the first pressure value, the second pressure value, the third pressure value and the fourth pressure value.
The first pressure value is subtracted from the second pressure value to obtain a first pressure difference value, the third pressure value is subtracted from the fourth pressure value to obtain a second pressure difference value, the second pressure value is subtracted from the first pressure value to obtain a third pressure difference value, and the fourth pressure value is subtracted from the fourth pressure value to obtain a fourth pressure difference value.
S130, acquiring correction parameters based on a preset mode.
The user device then obtains the user's characteristic parameters including height, body fat rate, gender, and the setting position of the stimulation electrodes 221. For the characteristic parameters, professional staff usually needs to measure the characteristic parameters of the user in the treatment stage, the characteristic parameters can be stored in user equipment after measurement, and when the characteristic parameters are used, the characteristic parameters can be called by inputting the identity information of the user into the user equipment. The user equipment judges the body posture of the user by calculating the pressure difference value, and then when the stimulation scheme is adjusted according to the body posture of the user, the four characteristic parameters generally have larger influence on posture judgment and adjustment of the stimulation scheme according to actual test experience, and the sensor parameter value of the piezoresistor sensor has influence on measurement of the pressure value. It is therefore necessary to combine the above-mentioned characteristic parameters with the sensor parameters of the piezoresistive sensor to calculate correction parameters, thereby correcting the calculation of the pressure difference.
First, the height affects the accuracy of judging the posture of the human body by the pressure difference. This is because there may be differences in the redistribution and skeletal structure of the human body with different heights, resulting in different pressure distributions applied in the same posture. For example, tall persons may apply more distraction than short persons in the same pose, while short persons may apply more concentration than tall persons in the same pose. Such a difference may affect the measurement result of the piezoresistive sensor, thereby affecting the accuracy of determining the posture of the human body by pressure.
Secondly, body fat rate affects the accuracy of judging the posture of the human body by pressure difference. This is because body fat rate is related to the distribution and density of body components, which may affect the measurement results of the piezoresistive sensor. For example, a person with a high body fat rate may exert more pressure in the same posture because adipose tissue is softer than muscle tissue, and deformation and compression are easily generated, thereby affecting the measurement result of the piezoresistive sensor. Whereas muscle tissue is relatively stiffer and more sensitive to pressure exerted on the body.
At the same time, sex also affects the accuracy of judging the posture of the human body by pressure. This is because there are differences in the body structure and body shape of the man and woman, thereby affecting the measurement result of the piezoresistive sensor. For example, a male is generally stronger than a female, may exert a greater pressure than a female in the same posture, and a relatively low center of gravity of the female may result in a more diffuse pressure distribution than a male in the same posture. These differences may have an influence on the measurement result of the pressure sensor, thereby affecting the accuracy of determining the posture of the human body by the pressure.
In addition, the location of the stimulation electrodes 221 affects the effect of the subsequent stimulation application, as different locations of the stimulation electrodes 221 may affect different nerve and muscle tissues, thereby producing different stimulation effects. Therefore, the setting position of the stimulation electrode 221 needs to be considered when correcting the pressure difference, so that the effect of the subsequent stimulation can be improved.
The user equipment obtains sensor parameter values of the piezo-resistive sensors, namely, resistance values corresponding to the four piezo-resistive sensors, a first resistance value of the first sensor 241, a second resistance value of the second sensor 242, a third resistance value of the third sensor 243, and a fourth resistance value of the fourth sensor 244.
Based on the first resistance value, the second resistance value, the third resistance value and the fourth resistance value, and combining the height, the body fat rate, the sex and the setting position of the stimulating electrode 221, the correction parameters are calculated through a preset matrix formula, and the specific formula is as follows:
。
wherein C is correction parameter, R 1 R is a first resistance value 2 At a second resistance value, R 3 R is a third resistance value 4 The fourth resistance value is H, H is the height of the user, S is the sex of the user, T is the body fat rate of the user, and W is the setting position of the stimulation electrode 221. The gender of the user is calculated by substituting 1 for the female according to 2 for the male. The setting position of the stimulation electrode 221 needs to convert the coordinate value into a numerical value according to the correspondence relationship.
C is calculated by a preset matrix formula 1 =R 1 ×H+R 2 ×T，C 2 =R 1 ×S+R 2 ×W，C 3 =R 3 ×H+R 3 ×S，C 4 =R 3 ×S+R 4 X W. Then, c=c 1 +C 2 +C 3 +C 4 。
S140, a first correction pressure difference value is obtained, wherein the first correction pressure difference value is obtained by multiplying the first pressure difference value and the correction parameter.
And S150, acquiring a second correction pressure difference value, wherein the second correction pressure difference value is obtained by multiplying the second pressure difference value and the correction parameter.
After the correction parameters and the pressure values are obtained, calculating a plurality of correction pressure difference values according to the correction parameters and the pressure values based on a third preset mode, wherein a specific calculation formula is as follows:
D 1 =C×|F 1 -F 2 |，D 2 =C×|F 3 -F 4 |，D 3 =C×|F 2 -F 1 |，D 4 =C×|F 4 -F 3 |
Wherein D is 1 For first correction of pressure difference, D 2 For the second corrected pressure difference, D 3 For the third corrected pressure difference, D 4 For the fourth correction pressure difference, C is the correction parameter, F 1 At a first pressure value F 2 At a second pressure value F 3 At a third pressure value F 4 Is the fourth pressure value.
S160, determining the body posture of the user according to the first correction pressure difference value and the second correction pressure difference value.
Referring to fig. 4, the posture monitoring device is configured as shown in the figure, the first corrected pressure difference is the difference between the upper pressure and the lower pressure, the second corrected pressure difference is the difference between the left pressure and the right pressure, the third corrected pressure difference is the difference between the lower pressure and the upper pressure, and the fourth corrected pressure difference is the difference between the right pressure and the left pressure. Finally, the user equipment compares the correction pressure difference value with a preset threshold value, and judges the body posture of the user according to the comparison result, wherein the judgment standard is as follows:
if the first correction pressure difference value is larger than a preset first threshold value, and the second correction pressure difference value is smaller than or equal to a preset second threshold value, or the fourth correction pressure difference value is smaller than or equal to a preset second threshold value, judging that the body posture is standing posture or sitting posture.
And if the first correction pressure difference value and the third correction pressure difference value are smaller than or equal to the first threshold value, and the second correction pressure difference value is smaller than or equal to the second threshold value, or the fourth correction pressure difference value is smaller than or equal to the second threshold value, judging that the body posture is the recumbent posture.
And if the first correction pressure difference value and the third correction pressure difference value are smaller than or equal to the first threshold value and the second correction pressure difference value is larger than the second threshold value, judging that the body posture is left lying.
And if the first correction pressure difference value and the third correction pressure difference value are smaller than or equal to the first threshold value and the fourth correction pressure difference value is larger than the second threshold value, judging that the body posture is right lying.
According to the actual situation, there is no case where the first corrected pressure difference or the third corrected pressure difference is greater than the first threshold value, and the second corrected pressure difference or the fourth corrected pressure difference is greater than the second threshold value, and thus no further discussion will be made.
The setting of the first threshold and the second threshold needs to be set according to the actual situations of different users, and needs to be further adjusted by combining algorithms such as deep learning, so that the specific values of the first threshold and the second threshold are not further specifically limited, and other embodiments can be adjusted according to the actual situations. Meanwhile, for the numerical values of the first threshold and the second threshold, the numerical values can be calculated according to different characteristic parameters of different users through a preset formula, and the specific calculation formula is as follows:
。
wherein G is 1 Is a first threshold value, G 2 As the second threshold value, α is a height weight value, β is a gender weight value, Ω is a body fat rate weight value, and δ is a set position weight value of the stimulation electrode 221. H is the height of the user, S is the sex of the user, T is the body fat rate of the user, and W is the setting position of the stimulating electrode 221. G 1 ' average first threshold value for statistical sample, G 2 ' is the average second threshold of the statistical samples. H 'is the average height of the statistical sample, S' is the average gender value of the statistical sample, T 'is the average body fat rate of the statistical sample, and W' is the average value of the implantation positions of the stimulation electrodes 221 of the statistical sample. The gender of the user is calculated by substituting 1 for the female according to 2 for the male. The setting position of the stimulation electrode 221 needs to convert the coordinate value into a numerical value according to the correspondence relationship.
After the user equipment acquires the body posture of the user, the user equipment needs to call a corresponding stimulation scheme according to the body posture of the user, the stimulation scheme is sent to the central control module 230 through the wireless communication module 210, after the central control module 230 receives the stimulation scheme, a control instruction corresponding to the conversion of the stimulation scheme is sent to the stimulation module 220, and the stimulation module 220 converts the conversion instruction into an electric signal and sends the electric signal to the plurality of stimulation electrodes 221, so that the stimulation electrodes 221 are controlled to apply stimulation. The stimulation schemes corresponding to different gestures are not identical for the same user, and the stimulation schemes corresponding to the same gesture are not identical for different users. For example, when the body posture of the user is judged to be a lying posture, the corresponding stimulation scheme can be to increase the intensity and frequency of the stimulation, and the specific increase amount also needs to be adjusted according to the actual situation of the user. Therefore, the present embodiment is not limited in detail, and other embodiments may be adjusted according to the actual situation. However, the body gesture and the corresponding stimulation scheme of the user are stored in the user device, and the user device can automatically send the corresponding stimulation scheme to the central control module 230 after acquiring the body gesture of the user, so that the user is stimulated correspondingly.
