The mobile terminal includes but is not limited to: a mobile phone, a tablet computer or a wearable device, etc. The fixed terminal includes: a personal computer (PC) or a projection device, etc.

In one embodiment, the electronic device may be a small-screen device whose screen area is smaller than a first preset value, and the small-screen device may not be convenient for the user's manual touch; or, the electronic device may be a large display device whose display area is larger than a second preset value. The second preset value is larger than the first preset value. The large display device here is a projection device, which is hung on the wall and may require a special control device for control. In this way, it is not easy to control when the user leaves the control device. In the embodiment of the present disclosure, the target user can wear a detection device for simplified control through EEG signals.

The preset objects include but are not limited to: operation controls, pictures or text or connections.

Exemplarily, the preset object may be: description information of goods or services available for purchase on a shopping page.

Exemplarily, the preset object may be a confirmation control and/or a cancel control in a dialog box and/or prompt information.

Exemplarily, the preset object may also be page turning controls such as “previous page” and “next page”.

The target user may be a user wearing a detection device for detecting brain waves, or a user viewing a preset object displayed by the electronic device.

The detection device may be pre-connected with the electronic device. This connection may be a wired connection or a wireless connection. For example, the wireless connection includes but is not limited to a Bluetooth connection or a WiFi direct connection, or a network connection is established through the Internet. The Internet may include: an access network and a core network, etc. The access network includes but is not limited to: an access network for cellular mobile communications and/or a WiFi network constructed by a WiFi hotspot. The core network is connected to the back end of the access network to realize data interaction between different access networks or multiple devices connected to the same access network. The data interaction includes: brain wave detection data.

In one embodiment, the brain waves can be detected by a detection device. As shown in FIG2 , the target user wears a brain-activated headband as a detection device to detect the target user's brain waves. In this way, the electronic device can receive the aforementioned brain waves from the detection device. For example, the electronic device receives the original signal of the brain wave from the detection device, and obtains brain waves of different frequencies by signal decomposition; according to the frequency range of the alpha brain wave and the beta brain wave, the alpha brain wave and the beta brain wave of the detected target user can be extracted.

The mobile phone held by the target user in FIG. 2 may be the electronic device in the embodiment of the present disclosure.

In one embodiment, the flashing light associated with the preset object may include: flashing light displayed within a display range corresponding to the preset object, but is not limited to flashing light displayed within a display interval of the preset object.

For example, a display screen is divided into multiple display intervals, and different operation controls are displayed in different display intervals. An operation control may occupy a whole display interval or only a part of the display interval.

In one embodiment, the flashing light associated with the preset object may further include at least one of the following:

Flashing lights displayed on preset objects;

A flashing light that surrounds a preset object;

In one embodiment, a flashing light is provided on or around a preset object. In this way, the preset object viewed by the target user will correspond to the flashing frequency of the flashing light, and generate alpha brain waves and beda brain waves corresponding to the flashing frequency. The corresponding relationship between the frequencies of the alpha brain waves and beda brain waves and the flashing frequency can be considered that the frequencies of the alpha brain waves and beda brain waves are positively correlated with the flashing frequency, respectively. For example, the higher the flashing frequency of the flashing light, the higher the frequencies of the alpha brain waves and beda brain waves.

It can be understood that the flickering light is a type of visible light, and the flickering light effect is displayed by a display screen of an electronic device or projected by a projector. For example, the flickering light may include: red light and/or blue light within the visible light band.

In one embodiment, if there are multiple operation controls, the flashing frequencies of the flashing lights corresponding to different preset objects are different.

In another embodiment, if there are multiple operation controls, the flashing frequencies of the flashing lights corresponding to different preset objects are different, and the light frequencies of the flashing lights are also different.

In the disclosed embodiment, at least the amplitudes of the alpha brain wave and the beta brain wave are obtained. A concentration value representing the degree of attention of the target user when viewing the preset object is determined based on the amplitudes of the two brain waves. The amplitudes of the alpha brain wave and the beta brain wave reflect the activity level of the target user's brain.

The technical solution provided by the disclosed embodiment, on the one hand, will combine the alpha brain waves and beta brain waves in the EEG signal to jointly determine the concentration value that characterizes the degree of concentration of the target user's attention when viewing the first page, so that the target user's intention (or intent) can be quickly determined, thereby generating a first type of control instruction corresponding to the user's intention (or intent), and controlling the electronic device to execute the control instruction; thereby reducing the control delay of the electronic device using EEG signals, improving the response rate of the electronic device controlled by EEG signals, and further improving user satisfaction. On the other hand, in order to accurately use EEG signals to control electronic devices, flashing lights corresponding to preset objects will be displayed, and the flashing frequencies of the flashing lights corresponding to different preset objects are different; further, the control accuracy is improved by the influence of flashing lights of different flashing frequencies on the EEG signals of the human brain.

In one embodiment, the flashing light may be displayed when the electronic device displays prompt information.

For example, the preset object includes: an operation control; S110 may include: after the display time of the first page reaches a first preset time, displaying a prompt message, wherein the prompt message has an operation control and a flashing light corresponding to the operation control.

The first page displayed by the electronic device may be a system-level page or an application-level page. The system-level page includes: a display page of the operating system. The application-level page includes: a display page of any application installed in the operating system.

The first page displays one or more targets, for example, product information or service information for online shopping. For another example, the target may be: pictures to be viewed and/or texts to be read by the target user.

When the first page is displayed, the continuous display of the first page is timed. If the display time of the first page reaches the first preset time, it means that the target user is not in a hurry to turn the page or perform other operations on the page, but wants to specify a certain operation on the target displayed on the first page. Therefore, the electronic device displays a prompt message at this time.

The prompt information may be displayed in various forms. For example, the forms used to display the prompt information include but are not limited to: a dialog box or a floating window.

The prompt information has prompt content and operation controls corresponding to the prompt content.

The prompt content can be used to prompt whether to confirm to execute the preset operation for the target. The preset operation includes but is not limited to at least one of the following:

Booking operations; for example, booking of transportation tickets, booking of online shopping products, etc.

Purchase action: purchase of online goods and/or services.

Collection operation; the collection operation includes but is not limited to: collection of links to online shopping products or services; or collection of articles and other content displayed on the first page;

Forwarding operation.

The forwarding operation includes: forwarding text and/or images on instant social platforms such as WeChat.

The above is an example of the preset operation, and the specific implementation is not limited to this.

In the disclosed embodiment, the alpha brain waves and beta brain waves in the EEG signals are combined to jointly determine a concentration value that characterizes the degree of concentration of the target user's attention when viewing the operating controls, so that the target user's intention (or intent) can be quickly determined, thereby generating control instructions corresponding to the user's intention (or intent) to control the electronic device to perform operations associated with the operating controls; thereby reducing the control delay of electronic devices using EEG signals, improving the response rate of electronic devices controlled using EEG signals, and improving control accuracy based on prompt information and flashing light corresponding to the operating controls, and further improving user satisfaction.

In one embodiment, a flashing light is provided on or around the operating control, so that the target user will generate alpha brain waves and beta brain waves corresponding to the flashing frequency of the flashing light according to which operating control the target user views.

The flickering light is a type of visible light, and the flickering light effect is displayed by a display screen of an electronic device or projected by a projector.

For example, the flashing light may include: red light and/or blue light within the visible light band.

In one embodiment, if there are multiple operating controls, the flashing frequencies of the flashing lights associated with different operating controls are different.

In another embodiment, if there are multiple operating controls, the flashing frequencies of the flashing lights associated with different operating controls are different, and the light frequencies of the flashing lights are also different.

In one embodiment, a confirmation control and/or a cancel control is displayed on the prompt information;

The flashing light comprises: a first flashing light flashing at a first frequency and a second flashing light flashing at a second frequency;

The first flashing light flashes within the display interval of the confirmation control; the second flashing light flashes within the display area of the cancellation control.

In one embodiment, the prompt information displays a confirmation control but does not display a cancel control. If an alpha brain wave having a first relationship with the flashing frequency of the flashing light displayed on or around the confirmation control is detected, and a beta brain wave having a second relationship with the flashing frequency of the flashing light displayed on or around the confirmation control is detected, then a concentration value for the confirmation control is calculated; if the concentration value meets the standard, it can be considered that the target user controls the electronic device to perform an operation associated with the confirmation control. If the concentration value does not meet the standard, or if an alpha brain wave having a first relationship with the flashing frequency of the flashing light displayed on or around the confirmation control is not detected, and a beta brain wave having a second relationship with the flashing frequency of the flashing light displayed on or around the confirmation control is not detected, it can be considered that the target user does not want the electronic device to perform an operation associated with the confirmation control.

In one embodiment, when the prompt information is displayed, the cancel control is displayed but the confirmation control is not displayed. If an alpha brain wave having a first relationship with the flashing frequency of the flashing light displayed on or around the cancel control is detected, and a beta brain wave having a second relationship with the flashing frequency of the flashing light displayed on or around the cancel control is detected, then the concentration value for the cancel control is calculated; if the concentration value meets the standard, it can be considered that the target user controls the electronic device to perform the operation associated with the cancel control. If the concentration value does not meet the standard, or the alpha brain wave having a first relationship with the flashing frequency of the flashing light displayed on or around the cancel control is not detected, and the beta brain wave having a second relationship with the flashing frequency of the flashing light displayed on or around the cancel control is not detected, it can be considered that the target user does not want the electronic device to perform the operation associated with the cancel control. In one embodiment, if it is determined that the target user does not want the electronic device to perform the operation associated with the cancel control, it can be considered that the target user wants to control the electronic device to perform the reverse operation of the operation associated with the cancel control.

In one embodiment, when the prompt information is displayed, a cancel control is displayed and a confirmation control is displayed, and if an alpha brain wave having a first relationship with the flickering frequency of the flickering light displayed on or around the cancel control is detected, and a beta brain wave having a second relationship with the flickering frequency of the flickering light displayed on or around the cancel control is detected, then a concentration value for the cancel control is calculated; and if an alpha brain wave having a first relationship with the flickering frequency of the flickering light displayed on or around the confirmation control is detected, and a beta brain wave having a second relationship with the flickering frequency of the flickering light displayed on or around the confirmation control is detected, then a concentration value for the confirmation control is calculated. And the flickering frequencies of the flickering light associated with the confirmation control and the flickering light associated with the cancel control are different.

If in one embodiment, when a confirmation control and a cancel control are displayed at the same time, if it is detected that the concentration value corresponding to the confirmation control meets the standard, and it is detected that the concentration value corresponding to the cancel control also meets the standard, then the time of the brain wave is delayed, and the concentration value is reconfirmed based on the brain wave detected within the delayed time, and the operation that needs to be performed by the electronic device is performed again.

In one embodiment, when a confirmation control and a cancel control are displayed at the same time, if it is detected that the concentration value corresponding to the confirmation control has met the standard, and it is detected that the concentration value corresponding to the cancel control has also met the standard, then the display of the flashing light associated with the confirmation control or the cancel control is stopped, and the frequency of the brain waves after the flashing light of one of the controls is cancelled is obtained. If the alpha brain waves and beta brain waves associated with the flashing light that continues to be displayed continue to be detected, the control operation associated with the operation control that continues to display the flashing light is executed, otherwise the operation of the operation control that stops the flashing light is executed.

In one embodiment, the S130 may include: determining the concentration value for executing the determination operation associated with the determination control based on the amplitude of the alpha brain wave having the first relationship with the first frequency and the amplitude of the beta brain wave having the second relationship with the first frequency according to frequency; or determining the concentration value for executing the cancellation operation associated with the cancellation control based on the amplitude of the alpha brain wave having the first relationship with the second frequency and the amplitude of the beta brain wave having the second relationship with the second frequency according to frequency.

In one embodiment, as shown in FIG3 , the S130 may include:

S131: Determine a first ratio between the amplitude energy of the alpha brain wave whose frequency at a first moment has a first relationship with the flickering frequency and the maximum amplitude energy of the alpha brain wave whose frequency has a first relationship with the flickering frequency;

S132: determining a second ratio between the amplitude energy of the Beda brain wave whose frequency has a second relationship with the flickering frequency at the first moment and the maximum amplitude energy of the Beda brain wave whose frequency has a second relationship with the flickering frequency;

S133: Obtain the concentration value according to the first ratio and the second ratio.

Amplitude energy is proportional to the square of the amplitude.

Through observation, it was found that the peak value of alpha brain waves and the trough value of beta brain waves, or the trough value of alpha brain waves and the peak value of beta brain waves, have a certain accompanying relationship.

The concentration value obtained as the independent variable using the first ratio and the second ratio as the independent variable can make the concentration value have a comparative range of variation. In this way, the gradient of the concentration value variation increases. In this way, the greater the gradient of the concentration value variation, the concentration value will quickly rise from a very small value to a larger value or drop to a smaller value, so that when the conditions are met, the first type of control instruction can be quickly generated, thereby improving the response rate of the electronic device.

In some other embodiments, determining the concentration value according to the amplitude of the alpha brain wave and the amplitude of the beta brain wave includes:

Determine a first ratio between an absolute value of the amplitude of the alpha brain wave whose frequency has a first relationship with the flicker frequency at a first moment and a maximum absolute value of the amplitude of the alpha brain wave whose frequency has a first relationship with the flicker frequency;

Determine a second ratio between the absolute value of the amplitude of the Beda brain wave whose frequency at the first moment has a second relationship with the flickering frequency and the maximum absolute value of the amplitude of the Beda brain wave whose frequency has a second relationship with the flickering frequency;

The concentration value is obtained according to the first ratio and the second ratio.

In one embodiment, obtaining the concentration value according to the first ratio and the second ratio includes:

The difference between the first ratio and the second ratio is calculated to obtain the concentration value.

For example, the concentration value is obtained by subtracting the difference between the first ratio and the second ratio; in another embodiment, the concentration value can also be obtained by adding the first ratio to the second ratio. In short, there are many ways to calculate the concentration value based on the first ratio and the second ratio, which are not limited to any of the above.

For example, the concentration value is calculated using the following formula:

In formula (1), is the amplitude energy of the alpha brain wave at time t, is the amplitude energy of the Beda brain wave at time t, E _α is the maximum amplitude energy of the alpha wave, and E _β is the maximum amplitude energy of the Beda brain wave.

In the disclosed embodiments, the amplitude of the alpha brain wave and the amplitude of the beta brain wave are both amplitudes of time domain waves.

In one embodiment, S140 may include: if the concentration value satisfies a preset condition, controlling the electronic device to perform an operation associated with the operation control.

The concentration value satisfies the preset conditions including but not limited to: the concentration value is located in a preset area.

Exemplarily, the concentration value satisfies preset conditions, including: a peak value of the concentration value is greater than a first threshold; and/or a trough value of the concentration value is less than a second threshold; wherein the second threshold is less than the first threshold.

Exemplarily, the preset objects are different commodities displayed on the shopping application page. If the concentration value of the brain waves with the flashing frequency corresponding to commodity A is detected to be greater than a first threshold, it can be considered that the purchase operation of commodity A is executed; if the concentration value of the brain waves with the flashing frequency corresponding to commodity A is detected to be less than a second threshold, it can be considered that the purchase operation of commodity A is cancelled.

A time domain waveform of a concentration value is shown in FIG4 . The concentration value also presents a certain periodicity. For example, a time domain waveform drawn based on discrete concentration values flips between positive and negative values once, corresponding to a cycle of the concentration value.

The first threshold may be the B value in FIG. 4 ; the second threshold may be the C value in FIG. 4 .

The concentration value between the first threshold and the second threshold is: a value outside the preset interval; and the concentration value greater than the first threshold and less than the second threshold is a value within the preset interval.

In FIG4 , time t1 is the peak value of the concentration value; time t2 is the trough value of the concentration value.

In one embodiment, in order to further improve the response rate of the electronic device, the electronic device determines whether to generate a first-class control instruction each time it obtains a concentration value, rather than waiting until the concentration value has crossed between positive and negative values at least once before determining whether to generate a first-class control instruction.

In this way, by determining whether the peak value of the concentration value is greater than the first threshold and whether the trough value of the concentration value is less than the first threshold, compared with determining whether the concentration value is within a preset interval alone, repeated control generation can be reduced, and unnecessary generation of control instructions and erroneous operations can be reduced.

For example, if the concentration value is greater than the first threshold, the electronic device is controlled to perform a purchase operation. Due to the continuity of the concentration value, repeated purchases may occur, which may lead to repeated purchases. However, this is obviously not what the user wants. Therefore, in the embodiment of the present disclosure, the peak value and trough value of the concentration value are used to determine the control of the electronic device to perform the corresponding operation, which can reduce the erroneous operation of the electronic device and further improve the user experience.

Exemplarily, the method further includes:

When the concentration value at the nth detection moment is within a preset interval, a first slope between the concentration value at the nth detection moment and the concentration value at the n-1th detection moment is determined, and a second slope between the concentration value at the nth detection moment and the concentration value at the n+1th detection moment is determined; the concentration value being within the preset interval includes: the concentration value being greater than the first threshold or the concentration value being less than the second threshold; wherein n is a positive integer;

If the sign of the first slope is opposite to the sign of the second slope, it is determined that the peak value of the concentration value is greater than the first threshold or the trough value of the concentration value is less than the second threshold.

The nth detection moment can be any detection moment of the concentration value, and one detection moment can correspond to a detection moment of the brain wave. The n-1th detection moment is the detection moment before the nth detection moment; the n+1th detection moment is the detection moment after the nth detection moment. The slope of the straight line is constructed in the two-dimensional coordinate system with the moment information of the detection moment and the concentration value. If it is found that the signs of the slopes of the two straight lines are opposite, it means that a peak value or a trough value of the concentration value has been experienced.

The sign of the first slope is opposite to the sign of the second slope, including:

The first slope is a positive number and the second slope is a negative number;

or,

The first slope is a negative number and the second slope is a positive number.

As for whether the concentration value is currently experiencing a peak value or a trough value, it can be determined based on the sign of the concentration value. Alternatively, if the sign of the slope switches from negative to positive, it can be considered that the concentration value has experienced a trough value. If the sign of the slope switches from positive to negative, it can be considered that it has experienced a peak value.

By fitting a straight line and based on the slope of the straight line, the peak value and the trough value of the concentration value can be quickly known, thereby further accelerating the generation of the first type of control instructions, thereby improving the response rate of the electronic device.

In some embodiments, the method further comprises:

Acquiring the eye waves of the target user when the first page and/or the prompt information is displayed;

The electrooculogram characteristics are obtained according to the electrooculogram characteristics, and the page switching of the electronic device is controlled according to the electrooculogram characteristics.

For example, controlling the page switching of the electronic device according to the electrooculographic characteristics includes but is not limited to:

According to the electrooculographic characteristics, the electronic device is controlled to switch to displaying the third page.

In one embodiment, the third page is: a historical page displayed by the electronic device before displaying the third page. In another embodiment, the third page may be: a next page after the first page.

Eye waves are a physiological waveform that reflects the eye movements of the target user.

The user's eye movement also reflects the target user's attention to the content displayed on the first page or prompt information, and thus can also reflect the user's intention or wish.

In the embodiment of the present disclosure, eye waves are introduced to control the electronic device to switch to display the third page. In this way, the electronic device is controlled to perform display switching, which enriches the control of the electronic device using brain electrical signals. Eye waves and brain waves are both types of the aforementioned brain electrical signals.

In one embodiment, the electrooculographic feature may include: the target user's blinking frequency and/or blinking amplitude. The amplitude of conscious blinking is different from the amplitude of unconscious blinking. In one embodiment, if the user's conscious blinking is detected according to the electrooculographic feature, the electronic device may be controlled to perform a page turning operation and switch to displaying the third page.

FIG7 is a schematic diagram of an electrooculogram waveform; FIG7 has a peak with a very high amplitude. In the disclosed embodiment, the electrooculogram feature may be a peak feature in the electrooculogram. If the amplitude value corresponding to the peak of the electrooculogram is greater than a specific value, it can be considered that a conscious blink has occurred. In the disclosed embodiment, the amplitude of the blink or the frequency of conscious blinking can be determined based on whether there is a peak feature, and whether to control the display switching of the electronic device.

In one embodiment, the electrooculographic characteristics include: blinking frequency;

The controlling the display switching of the electronic device according to the electrooculographic feature may include:

In order to improve the control accuracy and reduce the misoperation of the electronic device, the electrooculographic features described in the embodiment of the present disclosure include: blink frequency. And the blink frequency is the blink frequency with a blink amplitude greater than the amplitude threshold, so as to ensure that the target user consciously blinks to control the electronic device and reduce the misoperation caused by a single conscious blink.

The frequency threshold may be any positive integer. For example, the frequency threshold may be a positive integer not less than 2.

In one embodiment, the method further comprises:

If the concentration value satisfying the preset condition is not detected within a second preset time period after the first page is displayed, the electronic device is controlled to switch to displaying the second page.

By utilizing the concentration value that does not meet the preset conditions, the display page turning of the electronic device is controlled, thereby further enriching the brain wave signal control form of the electronic device.

In one embodiment, the second page may be a next page of the first page or a previous page of the first page.

For example, the first page is shopping page A. If a concentration value that meets the preset condition is detected within the second preset time period when shopping page A is displayed, it means that the target user is not interested in the content on shopping page A and can switch to the next shopping page B. The next shopping page B can be any shopping page that has not been displayed before, so that the target user can see the shopping information on shopping page B.

For another example, the first page is shopping page A. Based on the electrical characteristics detected by the eye waves, it is determined to control the electronic device to perform a page turning operation, and the electronic device returns to display the previous shopping page C; shopping page C was displayed before shopping page A.

The first preset duration and the second preset duration are two independent duration values. In one embodiment, the second preset duration may be greater than the first preset duration. The first preset duration may be the duration for triggering the electronic device to determine whether to display the prompt information. The second preset duration may be: the trigger duration for switching to the second page when no brain waves with a concentration value that meets the preset conditions are detected and/or eye waves that trigger the electronic device to switch to the third page are detected. In one embodiment, the start and end times of the second preset duration and the first preset duration are both calculated from the start time of the actual first page. After reaching the first preset duration, the electronic device displays the prompt information, so the display duration of the first page can be stopped; and the duration of whether the second preset duration is reached can continue to be counted. That is, the timing duration corresponding to the second preset duration can be extended from displaying the first page to displaying the prompt information.

The disclosed embodiment provides a control method of an electronic device, which can be applied to various scenarios, and is described below by taking an online shopping scenario as an example. If the shopping scenario is in, the first page currently displayed by the electronic device is an online shopping page.

This technology is applied to shopping scenarios, and the entire closed-loop shopping scenario of the online mall is completed through mind control. For example:

On the online shopping page, there are controls such as "next", "buy" and "previous" to confirm/cancel purchases and turn pages. You can use mobile shopping apps, such as Xiaomi Mall and other brand mall apps, to complete a series of operations that only require you to use your brain to control the products you want to buy.

First, the single-channel EEG headband collects EEG signals at the PF2 of the human forehead. The detection equipment collects the original waveform of the noise signal and can separate 4 different brain waves and 1 eye wave. These 4 brain waves include the aforementioned alpha brain waves and beta brain waves.

Then the Bluetooth transmits the EEG signal to the mobile phone APP, which analyzes the communication data and performs algorithm processing on the original waveform, separates the original waveform mentioned above, processes it with the concentration value algorithm, and records the number of eye movements in real time; finally, it judges the thresholds of the peaks and troughs of the concentration value curve and the electrooculogram threshold to implement corresponding operations.

The concentration value is defined as the difference between the amplitude energy of the alpha wave and the amplitude energy of the beta wave. The formula is the aforementioned formula (1):

As shown in Figure 4, within the same period of time, the concentration value changes in the range of [-100, 100], and the focus value changes in the range of [0, 100]. Generally, the focus value is calculated based on the amplitude of the alpha brain wave alone.

By combining the method of calculating the concentration value with the alpha brain wave and the beta brain wave, the concentration value change gradient becomes larger, so that the electronic device responds faster and the corresponding instructions are executed faster.

In addition, it solves the problem of long delays in issuing commands in the video, and is also a new secondary data processing method for raw brain waves. For the threshold judgment of the EEG concentration value, when the peak value at time t1 appears at a certain moment, the extreme value algorithm (that is, the slope change between the three points) is used to find the extreme point, and determine whether the maximum value meets the set B requirement, and finally execute the corresponding command, and the same applies to time t2. In this way, the EEG signal will not be repeatedly judged, and the command will be repeatedly executed, which will speed up the reaction while reducing memory and improving the accuracy of the command. The extreme points here include the peak value and trough value of the aforementioned concentration value.

As shown in Figure 5, first, the application (Application, App) on the mobile phone or other electronic devices controls the placement of red light flashing at frequency A and blue light flashing at frequency B at the two ends of the mobile phone screen, or the red/blue light flashing at frequency A/B periodically rotates around the selected product. Then the single-channel EEG headband collects the EEG signal of the human forehead PF2. The original waveform can be separated into 5 different waveform signals, namely 4 brain waves and 1 eye wave. The 4 brain waves include: Alpha brain waves and Beda brain waves. Then the EEG signal is transmitted to the mobile phone APP via Bluetooth, the communication data is analyzed, and the original waveform is processed by algorithm, mainly separating the alpha and beta brain waves and eye waves, and processing the concentration value algorithm, and recording the eye movement response in real time; finally, due to the stimulation of light flashing at different frequencies, the brain will respond to alpha and beta brain waves with different brain wave frequencies, and the concentration values of the corresponding alpha and beta brain waves will be judged by threshold. The eye movement characteristics are used to generate another control instruction for controlling the electronic device, and threshold judgments are made based on the dichotomy of the concentration curve and the electrooculogram threshold, thereby realizing different functions.

For a specific operation flow, please refer to FIG6 . The control method of the electronic device may include:

Obtain the original brain wave signal of the headband. Here, the original brain wave signal of the headband can be the original brain wave signal detected by any detection device worn on the head. When the detection device such as the headband detects the brain wave signal, there is a red light flashing at frequency A and a blue light flashing at frequency B on the electronic device;

Analyze the data, for example, by Fourier transform, to separate the alpha brainwaves, beta brainwaves and eye waves from the raw brainwave signal from the headband.

Extract the concentration value based on the amplitude capacity algorithm of alpha brain waves and beta brain waves;

When the eye wave is in a certain interval c, the first command (command-1) is executed. The control command can be any page turning command such as ; when the electronic device executes the page turning command, the page displayed on the screen is switched;

When a peak value of the concentration value of the brain wave in response to the red light flashing at frequency A is greater than the threshold value d1, the second command (command-2) is executed.

When the brain wave in response to the red light flashing at frequency B is greater than the threshold d2, the third command (command-3) is executed;

When no command threshold is detected within a certain period of time, the fourth command (command-4) is executed. The certain period of time here can be the aforementioned second preset time length.

In one embodiment, the threshold d1 and the threshold d2 may be equal or unequal. Here, the thresholds d1 and d2 may correspond to the aforementioned first threshold or B in FIG4 .

It can be understood that in some cases, if a certain trough value of the concentration value of the brain wave responded to the red light flashing at the A frequency is less than the threshold value f1, the execution of the second instruction (command-2) is canceled; and/or, when the concentration value of the brain wave responded to the red light flashing at the B frequency is less than the threshold value f2, the execution of the third instruction (command-3) is canceled. The threshold value f1 and the threshold value f2 here can be the aforementioned second threshold value.

First, the single-channel headband collects the original brain wave signal, and the red light flashing at the A frequency is used to separate the alpha brain wave, the beta brain wave and the eye wave based on the rhythm wave energy method. Then, the energy wave algorithm of the concentration is processed into a real-time concentration value, and the number of eye waves is screened out according to the peak interval threshold of the eye wave; finally, the threshold is judged. When the eye wave feature is in a certain interval c, the signal instruction command-1 is executed; when the human eye captures the red light flashing at the A frequency and responds to the corresponding brain wave, and its concentration value is greater than the threshold d1, the signal instruction command-2 is executed; when the human eye captures the red light flashing at the A frequency and responds to the corresponding brain wave, and its concentration value is greater than the threshold d2, the signal instruction command-3 is executed; when no command threshold is detected within a certain period of time, the signal instruction command-4 is executed. When distinguishing between the red and blue light, it is recommended to set it to both ends, which will improve the accuracy and have slightly fewer instructions. However, setting the lights to flash in a loop at different frequencies is similar to Hawking's typing system, which can implement a large number of instructions, but the efficiency may be relatively low.
