Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The technical solutions provided by the embodiments of the present disclosure relate to wearable devices and terminals, where the wearable devices may be smart bracelets, smart watches, smart sports shoes, and other smart devices installed on the limbs; the terminals may be mobile phones, Tablet computers, notebook computers, smart game consoles, and other smart devices are not limited in the embodiments of the present disclosure. In the related art, the limbs are used to receive the command corresponding to the operation issued by the brain, and then the operation corresponding to the command is executed on the terminal to realize the control of the terminal.

The embodiment of the present disclosure provides a signal control method, and the executive body implementing the method includes a wearable device and a terminal. Two sets of embodiments are arranged in the embodiments of the present disclosure according to different method implementation bodies, as follows:

Wearable device side

Fig. 1a is a flowchart showing a signal control method according to an exemplary embodiment, and the method is applied to a wearable device. As shown in Fig. 1a, the signal control method includes the following steps 101 and 102:

In step 101, the electromyography signal of the target limb is collected.

Among them, the EMG signal indicates the target action of the target limb.

For example, an EMG sensor or EMG neural interface is set on the wearable device, and the EMG sensor or EMG neural interface is closely attached to the target limb of the user, and the target limb is collected through the EMG sensor or EMG neural interface. Since the EMG signal collected by the EMG sensor or the EMG neural interface is a weak electrical signal, it is easily interfered by other signals of the body and the external environment and noise. The EMG neural interface is equipped with a signal conditioning circuit and an AD converter, and the collected EMG signals are amplified and filtered through the signal conditioning circuit to increase the signal-to-noise ratio of the EMG signals and convert the conditioned EMG The signal is converted into a digital EMG signal by an AD converter.

It should be noted that the target limb in this embodiment may be a limb that can fix the wearable device, such as a wrist, a foot, or a knee, which is not limited herein.

It should be noted that, the EMG sensor and EMG neural interface in this embodiment may adopt the EMG sensor and EMG neural interface in the prior art, which will not be repeated here.

In step 102, a data signal is sent to the terminal according to the EMG signal, so that the terminal executes a second operation instruction corresponding to the data signal before acquiring the first operation instruction according to the target action, and the second operation instruction is the same as the first operation instruction .

For example, when the wearable device sends a data signal to the terminal, it is assumed that the terminal receives the first operation instruction sent by the user according to the target action with a delay of 40ms after executing the second operation instruction corresponding to the data signal. The operation instructions are the same, so before 40ms, the terminal is equivalent to having executed the first operation instruction, and the user's muscle system also has a certain feedback time. Suppose the feedback time is 30ms. In this way, when the user presses the button or mouse or touch screen , there is only a 10ms time difference between the time when the user presses the button or the mouse or the touch screen and the terminal executes the second operation command corresponding to the data signal. The first operation instruction is executed, the control time is shortened, and the user experience is further improved.

Optionally, the wearable device sends a data signal to the terminal through a wired data transmission interface, or sends a data signal to the terminal through a wireless transmission module. Wherein, the wired data transmission interface includes one of RS232 interface, RS242, and RS485 interface, and the wireless transmission module includes one of a WIFI module, a Zigbee wireless module, and a Bluetooth module; the wearable device sends data in a wired manner When there is a signal, the terminal side is equipped with a corresponding RS232 interface or RS242 or RS485 interface, etc., and then connect the wearable device and the terminal through the corresponding data cable, so that the wearable device can send the data signal to the terminal by wire; in the wearable device When the data signal is sent wirelessly, a WIFI module, a Zigbee wireless module or a Bluetooth module, etc. are correspondingly provided on the terminal side, so that the wearable device can send the data signal to the terminal wirelessly.

Optionally, the specific method for sending a data signal to the terminal according to the EMG signal is as follows:

In the first method, the wearable device sends the EMG signal to the terminal, and the data signal at this time is the EMG signal.

In the second method, the wearable device extracts the characteristic information of the electromyographic signal; acquires a data signal according to the characteristic information of the electromyographic signal, and sends the data signal to the terminal.

For example, the wearable device performs fast Fourier transform on each collected EMG signal to obtain the spectrum or power spectrum of each EMG signal, which can reflect the change of each EMG signal in the frequency dimension, and then pass The frequency of each EMG signal is obtained from the distribution of the spectrum or power spectrum, and the frequency of each EMG signal is displayed, so that the user can determine the frequency of each EMG signal, the target action of the target limb, and the target limb through experiments. The corresponding relationship between the instructions corresponding to the target action of the When the EMG signal is used, fast Fourier transform is performed on the EMG signal to obtain the spectrum or power spectrum of the EMG signal, and finally the frequency of the EMG signal is obtained according to the distribution of the spectrum or power spectrum of the EMG signal, and then It is determined whether the frequency of the EMG signal is stored, and if it is determined that the frequency of the EMG signal is stored, the instruction corresponding to the frequency of the EMG signal is searched, the processing of the collected EMG signal is realized, and the myoelectric signal is obtained. The command corresponding to the electrical signal, and then send a data signal to the terminal according to the command. The data signal at this time is this command, and this command is also the second operation command, so that the terminal directly executes the second operation command and realizes the terminal's self-confidence. Control, the terminal's control of itself includes the control of various interfaces displayed on the terminal, the control of the touch screen of the terminal, or the control of the keys of the terminal, etc., which is not limited in this embodiment.

For example, a Tetris game is installed on the terminal, and the user controls the game by pressing the transform button, the down button, the left button and the right button. The number of collected EMG signals is four, and the wearable device is on After each EMG signal is processed, the frequency of the first EMG signal is 1HZ, the frequency of the second EMG signal is 2HZ, the frequency of the third EMG signal is 3HZ, and the frequency of the fourth EMG signal is It is 4HZ, the user can know through experiments that the target action of the target limb corresponding to the frequency of the first EMG signal is 1HZ as "press the deformation button", and the target action of the target limb corresponding to the frequency of the second EMG signal of 2HZ is "Press the direction". Press the button", the target action of the target limb corresponding to the frequency of the third EMG signal is "Press the left button", and the target action of the target limb corresponding to the frequency of the fourth EMG signal is "Press the right button". ”, set the command corresponding to “Press the deformation button” as the deformation command, set the command corresponding to “Press the down button” as the downward command, set the corresponding command of “Press the left button” as the left command, set The command corresponding to "Press the right button" is the right command, and then the frequency of each EMG signal and the instruction of the corresponding target action of the target limb are stored in the wearable device. When the wearable device collects the EMG signal When the EMG signal is processed, if the frequency of the EMG signal is 1HZ, it is determined whether the frequency of the EMG signal is 1HZ stored in the wearable device. Then the instruction corresponding to the frequency 1HZ of the EMG signal is found to be the deformation instruction, and the wearable device sends the data signal to the terminal, that is, the deformation instruction is sent to the terminal, so that the terminal executes the deformation instruction when it receives the deformation instruction. The currently running Tetris is deformed to achieve direct control of the Tetris game. After that, the user will send a deformation command to the terminal through the deformation button. At this time, when the terminal receives the deformation command, it directly ignores the deformation command, making the The user feels that the current Tetris is deformed just after pressing the deformation button, which improves the user experience; in the same way, the command corresponding to the frequency of the EMG signal 2HZ can be obtained as the downward command; the frequency of the EMG signal corresponds to 3HZ The command is leftward command; the command corresponding to the frequency of EMG signal 4HZ is rightward command.

For example, after collecting the EMG signal, the wearable device extracts the time-domain characteristic data or frequency-domain characteristic data of each EMG signal, wherein the time-domain characteristic data mainly includes the integral EMG value, the root mean square value, the absolute value Value integration, zero-crossing points, variance, Willison amplitude, time series model of EMG signal and EMG signal histogram, etc. For the specific method of using time domain method to analyze and extract the time domain characteristic data of EMG signal, please refer to the corresponding existing The method in the technology is not repeated in this embodiment.

The frequency characteristic data mainly includes the average power, the average frequency and the median frequency. For the specific method of using the frequency domain method to analyze and extract the frequency domain characteristic data of the EMG signal, please refer to the corresponding method in the prior art, and this embodiment will not be repeated here. Repeat.

Taking the extraction of the frequency-domain feature data of the EMG signal as an example, after the wearable device obtains the frequency-domain feature data of each EMG signal, it uses all the frequency-domain feature data of each EMG signal as training data. The naive Bayes classifier is preset on the device, and then each training data is input into the naive Bayes classifier, and then the instruction corresponding to the target action of the target limb calculated by the naive Bayes classifier is obtained, and the The calculated command is compared with the known command corresponding to the target action of the target limb, and the parameters in the naive Bayes classifier are adjusted according to the comparison result, so that the command calculated by the naive Bayes classifier is finally the same as the known command. The commands corresponding to the target actions of the target limbs are the same. At this time, the naive Bayes classifier is the classifier model obtained by training.

When the wearable device uses the classifier model to obtain the instruction corresponding to the EMG signal, the collected EMG signal extracts the frequency domain feature data of the EMG signal according to the above method, and then extracts the frequency domain feature of the EMG signal. The data is input into the classifier model to predict the instruction, realize the processing of the EMG signal, and obtain the instruction corresponding to the EMG signal, and then send the data signal to the terminal according to the instruction. The data signal at this time is this instruction, this instruction That is, the second operation instruction, so that the terminal directly executes the second operation instruction and realizes the terminal's control of itself. The terminal's control of itself includes the control of various interfaces displayed on the terminal, the control of the terminal touch screen, or the control of the terminal The control of buttons, etc., is not limited in this embodiment.

For example, a Tetris game is installed on the terminal, and the user controls the game by pressing the transform button, the down button, the left button and the right button. The number of collected EMG signals is four, and the wearable device is on After the EMG signals are processed, the frequency domain characteristic data of the first EMG signal is 1HZ, the frequency domain characteristic data of the second EMG signal is 2HZ, and the frequency domain characteristic data of the third EMG signal is 3HZ , the frequency domain characteristic data of the fourth EMG signal is 4HZ, and the user can know through experiments that the target action of the target limb corresponding to the frequency domain characteristic data 1HZ of the first EMG signal is "press the deformation button", and the second EMG signal The target action of the target limb corresponding to the signal frequency 2HZ is "press the down button", the target action of the target limb corresponding to the frequency 3HZ of the third EMG signal is "press the left button", and the fourth EMG signal's target action is "press the left button". The target action of the target limb corresponding to the frequency of 4HZ is "press the right button", set the command corresponding to "press the deformation button" as the deformation command, set the command corresponding to "press the down button" as the downward command, and set " The command corresponding to "Press the left button" is the left command, and the command corresponding to "Press the right button" is set to the right command. The data is training data, for example, select 0.98HZ, 0.99HZ, 0.995HZ, 1HZ, 1.05HZ, 1.1HZ, etc. as training data, input these training data into Naive Bayes classifier respectively, and then obtain the Naive Bayes The target action of the target limb calculated by the classifier, check whether the command corresponding to the target action of the target limb calculated by the naive Bayes classifier is a deformation command, if not, adjust the parameters in the naive Bayes classifier, and finally The instructions calculated by the Naive Bayesian classifier are the same as the instructions corresponding to the known target movements of the target limbs; the same method is used to train other frequency domain feature data, and finally the classifier model is obtained. When the wearable device collects the EMG signal, after processing the EMG signal, if the frequency domain characteristic data of the EMG signal is 1HZ, then input the frequency domain characteristic data 1HZ into the classifier model, and the classifier model calculates The command corresponding to the frequency domain characteristic data 1HZ is a deformation command, and the wearable device sends the data signal to the terminal, that is, the deformation command is sent to the terminal, so that when the terminal receives the deformation command, it executes the deformation command, so that the currently running Tetris is deformed to achieve direct control of the Tetris game. After that, the user will send a deformation command to the terminal through the deformation button. At this time, when the terminal receives this deformation command, it will directly ignore the deformation command, making the user feel The current Tetris is deformed just after pressing the deform button, which improves the user experience.

In the same way, it can be obtained that the command corresponding to the frequency domain characteristic data 2HZ of the EMG signal is a downward command; the command corresponding to the frequency 3HZ of the EMG signal is a left command; the command corresponding to the frequency 4HZ of the EMG signal is a rightward command. instruction, which will not be repeated in this embodiment.

It should be noted that the method for the wearable device to obtain the corresponding command according to the time-domain characteristic data of the EMG signal is the same as the above-mentioned method for obtaining the corresponding command according to the frequency-domain characteristic data of the EMG signal. It is not repeated here.

In the technical solution provided by the embodiments of the present disclosure, after collecting the EMG signal, the wearable device processes the EMG signal, and then sends a data signal to the terminal according to the processed EMG signal. The signal is the second operation instruction, so that when the user sends the first operation instruction to the terminal, the terminal has executed the second operation instruction before receiving the first operation instruction, which saves the processing time of the EMG signal by the terminal, and further The user feels that the terminal executes the first operation instruction while sending the first operation instruction, without waiting for the time for the user to send the first operation instruction to the terminal, which shortens the control time and improves the user experience.

Further, as shown in FIG. 1b, after step 102 is performed, the following steps 103 and 105 are further included:

In step 103, a response message sent by the terminal is received.

Wherein, the response message carries a success identifier or a failure identifier of the terminal receiving the data signal.

It should be noted that, according to the different contents indicated by the received response message, the following steps are also different. When it is determined that the response message carries the success identifier of the received data signal, step 104 is performed; When the failure flag of the data signal is identified, step 105 is executed.

In step 104, when it is determined that the response message carries a success identifier for receiving the data signal, the sending success information is displayed.

In step 105, when it is determined that the response message carries the failure flag of receiving the data signal, the data signal is re-sent to the terminal according to the myoelectric signal.

For example, when the wearable device receives the response message, it parses the response message, and determines whether the response message carries the success identifier of data signal transmission or the failure identifier of data signal transmission. If it is determined to be the success identifier of data signal transmission, Then the voice broadcasts the success information, or vibrates the wearable device, so that the user knows that the data signal is sent successfully; if it is determined that it is the failure sign of the data signal transmission, the data signal is sent to the terminal again according to the EMG signal to ensure that the terminal receives the data signal. correct data signal.

terminal side

Fig. 2a is a flowchart showing a signal control method according to an exemplary embodiment, and the method is applied to a terminal. As shown in Fig. 2a, the signal control method includes the following steps 201 to 203:

In step 201, a data signal is received.

For example, the terminal receives the data signal sent by the wearable device through the wired data transmission interface or the wireless transmission module. For the specific type of the wired data transmission interface and the type of the wireless transmission module, please refer to the description in the above step 101. Repeat.

It should be noted that when the data signal sent by the wearable device to the terminal is an EMG signal, the data signal received by the terminal is an EMG signal; when the data signal sent by the wearable device to the terminal is the target action corresponding to the target limb When the command is given, the data signal received by the terminal is the command corresponding to the target action of the target limb.

In step 202, a second operation instruction corresponding to the data signal is executed.

For example, if the data signal is an EMG signal, the terminal needs to process the data signal, and execute the corresponding second operation instruction according to the processed data signal; if the data signal is an instruction corresponding to the target action of the target limb, then The data signal is the second operation instruction, and the terminal directly executes the second operation instruction.

Optionally, when the data signal is an EMG signal, the specific method for executing the second operation instruction corresponding to the data signal is as follows:

extracting characteristic information of the data signal;

Acquire a second operation instruction according to the characteristic information of the data signal, and execute the second operation instruction.

For example, after the terminal receives the data signal, it needs to process the data signal. At this time, the data signal is the EMG signal collected by the wearable device. The terminal performs fast Fourier transform on each data signal to obtain each data signal. The frequency spectrum or power spectrum can reflect the change of each data signal in the frequency dimension, and then obtain the frequency of each data signal through the distribution of the spectrum or power spectrum, and display the frequency of each data signal, so that users can pass The experiment determines the correspondence between the frequency of each data signal, the target action of the target limb, and the instruction corresponding to the target action of the target limb, and then stores in the terminal the frequency of each data signal and the instruction corresponding to the target action of the target limb In this way, when the terminal receives the data signal, it performs fast Fourier transform on the data signal to obtain the frequency spectrum or power spectrum of the data signal, and finally obtains according to the distribution of the frequency spectrum or power spectrum of the data signal. The frequency of the data signal, and then determine whether the frequency of the data signal is stored. If it is determined that the frequency of the data signal is stored, the command corresponding to the frequency of the data signal is searched to realize the processing of the received data signal. The processed data signal is an instruction corresponding to the target action of the target limb. This instruction is also the second operation instruction. The terminal directly executes the second operation instruction to realize the terminal's control over itself. The control of each interface on the terminal, the control of the touch screen of the terminal, or the control of the keys of the terminal, etc., are not limited in this embodiment. For an example of using this method to process the data signal, reference may be made to the corresponding description in the foregoing step 102, which is not repeated in this embodiment.

Exemplarily, the terminal extracts time-domain characteristic data or frequency-domain characteristic data of each data signal, wherein the time-domain characteristic data mainly includes the integral EMG value, the root mean square value, the absolute value integral, the number of zero-crossing points, the variance, and the Willison amplitude. value, the time sequence model of the EMG signal, the EMG signal histogram, etc., the specific method of using the time domain method to analyze and extract the time domain characteristic data of the data signal may refer to the corresponding method in the prior art, and this embodiment will not be repeated here. Repeat. The frequency characteristic data mainly includes the average power, the average frequency and the median frequency. For the specific method of using the frequency domain method to analyze and extract the frequency domain characteristic data of the data signal, reference may be made to the corresponding methods in the prior art, which will not be repeated in this embodiment. .

Taking the frequency domain feature data extraction of the data signal as an example, after the terminal obtains the frequency domain feature data of each data signal, it uses all the frequency domain feature data of each data signal as training data, and pre-sets Naive Bayes on the terminal. Then input each training data into the naive Bayes classifier, and then obtain the instruction corresponding to the target action of the target limb calculated by the naive Bayes classifier, and the calculated instruction and the known Compare the instructions corresponding to the target actions of the target limbs, and adjust the parameters in the Naive Bayes classifier according to the comparison results, and finally make the instructions calculated by the Naive Bayes classifier correspond to the known target actions of the target limbs. The instructions are the same. At this time, the naive Bayes classifier is the classifier model obtained by training.

When the terminal adopts the classifier model to obtain the target action of the target limb corresponding to the data signal, the terminal extracts the frequency domain characteristic data of the data signal from the received data signal according to the above method, and then inputs the frequency domain characteristic data of the extracted data signal. The classifier model predicts the command and realizes the processing of the data signal. The processed data signal is the command corresponding to the target action of the target limb. This command is also the second operation command, and the terminal directly executes the second operation command. The control of the terminal on itself is realized, and the control of the terminal on itself includes the control of various interfaces displayed on the terminal, the control of the touch screen of the terminal, or the control of the keys of the terminal, etc., which is not limited in this embodiment. For an example of using this method to process the data signal, reference may be made to the corresponding description in the foregoing step 102, which is not repeated in this embodiment.

It should be noted that the method for the terminal to obtain the corresponding command according to the time-domain characteristic data of the data signal is the same as the above-mentioned method for obtaining the corresponding command according to the frequency-domain characteristic data of the data signal. Repeat.

In step 203, if a first operation instruction is obtained according to the target action, execution of the first operation instruction is prohibited, and the first operation instruction is the same as the second operation instruction.

For example, after the terminal executes the second operation instruction corresponding to the data signal, if the terminal obtains the first operation instruction corresponding to the action according to the target, at this time, the first operation instruction is compared with the second operation instruction, and the first operation instruction is determined after determining the first operation instruction. When the operation instruction is the same as the second operation instruction, the first operation instruction is ignored to avoid repeated execution of the same instruction.

In the technical solution provided by the embodiments of the present disclosure, after receiving the data signal, the terminal needs to process the data signal, and the time required for the terminal to process the data signal can be ignored for the feedback time of the user's muscles, so that , when the user sends the first operation instruction to the terminal, since the terminal has executed the second operation instruction corresponding to the data signal before receiving the first operation instruction, and the second operation instruction is the same as the first operation instruction, it can make The user feels that the terminal executes the first operation instruction while sending the first operation instruction, without waiting for the user to send the first operation instruction to the terminal, which shortens the control time and improves the user experience.

Further, as shown in Figure 2b, after step 201 is performed, step 204 is further included:

In step 204, a response message is sent to the wearable device.

Wherein, the response message carries a success identifier or a failure identifier of the terminal receiving the data signal.

For example, when the terminal receives the data signal, it needs to determine whether the data signal is received completely and whether there is any packet loss. If it is determined that the data signal is complete and there is no packet loss, it is determined that the data signal is successfully received, and at this time, it is reported to the wearable device that the carrying is successful. If it is determined that the data signal is incomplete and there is packet loss, it is determined that the receiving of the data signal fails, and at this time, the wearable device is fed back a response message carrying the failure identification, so that the wearable device sends the data signal to the terminal again, and the terminal restarts Receive data signals to ensure the accuracy of data signals received by the terminal.

The implementation process is described in detail below through several embodiments.
