[0085] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0086] like Figure 1 As shown, an embodiment of the present disclosure provides a control method of an electronic device, and the control method is applied to the electronic device, including:

[0087] S110: display the first page;

[0088] S120: Acquire brain waves of the target user when the first page is displayed, wherein the brain waves include: alpha brain waves and beta brain waves;

[0089] S130: determining a concentration value according to the amplitude of the alpha brain wave and the amplitude of the beta brain wave;

[0090] S140: Generate a first type of control instruction for controlling the electronic device according to the concentration value. In the embodiment of the present disclosure, the electronic device includes but is not limited to: various mobile terminals and / or fixed terminals. 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.

[0091] 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.

[0092] 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.

[0093] The first page displays one or more targets, such as 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.

[0094] The target user may be a user wearing a detection device for detecting brain waves, or a user viewing the first page. The detection device may be connected to the electronic device in advance. This connection may be a wired connection or a wireless connection. For example, a 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.

[0095] In one embodiment, the brain waves can be detected by a detection device. Figure 2 As shown, the target user wears a brain-activated headband as a detection device to detect the target user's EEG signal. 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 EEG signal 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.

[0096] Figure 2 The mobile phone held by the target user may be the electronic device in the embodiment of the present disclosure.

[0097] In the disclosed embodiment, at least the amplitudes of the alpha brain wave and the beta brain wave are obtained. The concentration value representing the attention level of the target user when viewing the first page 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.

[0098] In the embodiment of the present disclosure, the concentration value is positively correlated with the concentration of the target user when viewing the first page.

[0099] A first type of control instruction to be executed by the control electronic device is generated according to the concentration value.

[0100] For example, in one embodiment, if the concentration value is within a preset interval, a first type of control instruction to be executed by the electronic device is generated; and / or, if the concentration value is outside the preset interval, the first type of control instruction to be executed by the electronic device is not generated.

[0101] In the embodiment of the present disclosure, the first type of control instruction may be: a control instruction other than controlling the electronic device to execute display switching, and of course, may also be a control instruction for controlling the electronic device to execute display switching.

[0102] If the first type of control instruction is: a control instruction other than controlling the electronic device to perform display switching, it may be an operation instruction for one or more targets displayed on the first page. Of course, the execution result of the operation instruction will trigger the electronic device to switch the display. This first type of control instruction is not an instruction to directly control the electronic device to switch the display. For example, the first type of control instruction is an instruction to determine online shopping. The electronic device will send a purchase request based on the goods or services displayed on the first page and receive a payment request returned by the server based on the purchase request; at this time, the payment request will trigger the electronic device to switch to the payment page, but the payment page is not directly instructed to be executed by the first type of control instruction, but is triggered by the execution result of the first type of control instruction.

[0103] In summary, in the embodiments of the present disclosure, 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 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) to control the electronic device to execute the control instruction; thereby reducing the control delay of electronic devices using EEG signals, improving the response rate of controlling electronic devices using EEG signals, and further improving user satisfaction.

[0104] In one embodiment, Figure 3 As shown, the S130 may include:

[0105] S131: Determine a first ratio between the amplitude energy of the alpha wave at a first moment and the maximum amplitude energy of the alpha wave;

[0106] S132: Determine a second ratio between the amplitude energy of the Beda brain wave at the first moment and the maximum amplitude energy of the Beda brain wave;

[0107] S133: Obtain the concentration value according to the first ratio and the second ratio.

[0108] Amplitude energy is proportional to the square of the amplitude.

[0109] 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.

[0110] 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.

[0111] 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 comprises:

[0112] determining a first ratio between an absolute value of the amplitude of the alpha wave at a first moment and a maximum absolute value of the amplitude of the alpha wave;

[0113] Determining a second ratio between the absolute value of the amplitude of the Beda brain wave at the first moment and the maximum absolute value of the amplitude of the Beda brain wave;

[0114] The concentration value is obtained according to the first ratio and the second ratio.

[0115] In one embodiment, obtaining the concentration value according to the first ratio and the second ratio includes:

[0116] The difference between the first ratio and the second ratio is calculated to obtain the concentration value.

[0117] 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.

[0118] For example, the concentration value is calculated using the following formula:

[0119]

[0120] In formula (1), is the amplitude energy of the alpha brain wave at time t, is the amplitude energy of Beda brainwave at time t, E α is the maximum energy of the alpha wave amplitude, E β It is the maximum energy of the amplitude of Beda brain waves.

[0121] 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.

[0122] In some embodiments, the first type of instructions includes: a confirmation instruction and / or a cancellation instruction for performing a predetermined operation on the current target displayed on the first page;

[0123] The S140 may include: if the peak value of the concentration value is greater than a first threshold, generating the determination instruction for controlling the electronic device to perform the predetermined operation; and / or, if the trough value of the concentration value is less than a second threshold, generating the cancellation instruction for controlling the electronic device to cancel the execution of the predetermined operation; wherein the second threshold is less than the first threshold.

[0124] like Figure 4 The concentration value also shows a certain periodicity. For example, a time domain waveform diagram drawn based on discrete concentration values ​​flips between positive and negative values ​​once, corresponding to a cycle of the concentration value.

[0125] The first threshold may be Figure 4 The second threshold value may be Figure 4 The C value in .

[0126] 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.

[0127] exist Figure 4 In the figure, time t1 is the peak value of the concentration value; time t2 is the trough value of the concentration value.

[0128] 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.

[0129] 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 solely determining whether the concentration value is within a preset interval, the repeated generation of the first type of control instructions can be reduced, thereby reducing unnecessary generation of control instructions and erroneous operations.

[0130] For example, assuming that the first type of control instruction is a purchase instruction that controls an electronic device to perform a purchase operation, the first type of control instruction is generated once the concentration value is greater than a first threshold value. Due to the continuity of the change in the concentration value, the purchase instruction may be repeatedly generated, resulting in repeated purchases and the like. 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 whether to generate the first type of control instruction, which can reduce the misoperation of the electronic device and further improve the user experience.

[0131] Exemplarily, the method further includes:

[0132] 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;

[0133] 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.

[0134] 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.

[0135] The sign of the first slope is opposite to the sign of the second slope, including:

[0136] The first slope is a positive number and the second slope is a negative number;

[0137] or,

[0138] The first slope is a negative number and the second slope is a positive number.

[0139] 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.

[0140] 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.

[0141] In one embodiment, the predetermined operation includes one of the following:

[0142] Booking operations; for example, booking transportation tickets, booking online shopping products, etc.

[0143] Purchase action: purchase of online goods and / or services.

[0144] 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;

[0145] Forwarding operation.

[0146] The forwarding operation includes: forwarding text and / or images on instant social platforms such as WeChat.

[0147] In some embodiments, the method further comprises:

[0148] Acquiring eye waves of the target user when the first page is displayed;

[0149] Acquiring electrooculographic characteristics according to the electrooculographic waves;

[0150] A second type of control instruction for controlling the electronic device is generated according to the electrooculographic feature; wherein the second type of control instruction is different from the first type of control instruction.

[0151] Eye waves are a physiological waveform that reflects the eye movements of the target user.

[0152] The user's eye movement also reflects the target user's attention to the content displayed on the first page, and thus can also reflect the user's intention or willingness.

[0153] In the disclosed embodiment, eye waves are introduced to generate the second type of control instructions for electronic devices. The second type of control instructions can control the electronic device to perform corresponding operations, for example, control the electronic device to perform display switching, enriching the control of electronic devices using brain waves. Eye waves and brain waves are both types of the aforementioned brain waves.

[0154] In one embodiment, the electrooculogram 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 electrooculogram feature, the second type of control instruction may be generated.

[0155] Figure 7 is a waveform diagram of an eye wave; Figure 7 In the disclosed embodiment, the electrooculogram feature may be a peak feature in the electrooculogram wave. If the amplitude value corresponding to the peak of the electrooculogram wave is greater than a specific value, it can be considered that a conscious blink has occurred. In the disclosed embodiment, the blink amplitude or the frequency of conscious blinking can be determined based on whether there is a peak feature, and whether to generate a second type of control instruction.

[0156] In one embodiment, the electrooculographic characteristics include: blinking frequency;

[0157] The generating, according to the electrooculographic feature, a second type of control instruction for controlling the electronic device comprises:

[0158] When the blinking frequency is higher than the frequency threshold, control is generated to switch the electronic device to a second page, where the second page is the page displayed by the electronic device at a previous moment.

[0159] 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.

[0160] The frequency threshold may be any positive integer. For example, the frequency threshold may be a positive integer not less than 2.

[0161] In one embodiment, the method further comprises:

[0162] If the first and second control instructions are not detected within a preset time period of displaying the first page, a third control instruction is generated to control the electronic device, wherein the third control instruction is different from the first and second control instructions.

[0163] If the brain waves and / or eye waves of the first type of control instructions and / or the second type of control instructions are not detected within the predetermined time of displaying the first page, a third type of control instruction is generated. The third type of control instruction can be any instruction other than the first type of control instruction and the second type of control instruction, thereby further enriching the brain wave signal control form of the electronic device.

[0164] In one embodiment, the third type of control instruction includes one of the following:

[0165] A control instruction for controlling the electronic device to switch to a third page, wherein the third page is a page that has not been displayed at the current moment and at a previous moment;

[0166] A control instruction to control the electronic device to close the application corresponding to the first page.

[0167] For example, the first page is shopping page A. If the first type of control instruction and / or the second type of control instruction is not generated within the preset display time of shopping page A, 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.

[0168] For another example, the first page is shopping page A. If the electronic device generates a second type of control instruction, it returns to display the previous shopping page C; shopping page C was displayed before shopping page A.

[0169] In one embodiment, the method further comprises:

[0170] After generating a control instruction, outputting prompt information, wherein the control instruction includes any one of the first type of control instruction, the second type of control instruction to the third type of control instruction;

[0171] The brain waves when the prompt information is detected are obtained, and the concentration value is determined according to the amplitude of the alpha brain wave and the amplitude of the beta brain wave in the brain wave; according to the concentration value, it is determined whether to execute the generated control instruction.

[0172] For example, the prompt information is displayed on the first page in the form of a prompt dialog box, which has an "OK" control and / or a "Cancel" control; based on the electrooculographic characteristics of the concentration value of the brain wave, it is determined whether the target user pays more attention to the "OK" control or the "Cancel" control, thereby determining whether to perform the corresponding operation.

[0173] Closing the application corresponding to the first page, if the first page is an online shopping page, is equivalent to the electronic device closing the online shopping application after the third control instruction is executed.

[0174] Of course, the above is only an example of the third type of control instructions. There are many ways to implement it, not limited to any of the above examples.

[0175] 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 place, the first page currently displayed by the electronic device is an online shopping page.

[0176] 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:

[0177] 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.

[0178] 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 EEG 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.

[0179] 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.

[0180] 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 above formula (1).

[0181] like Figure 4 As shown in the figure, in the same period of time, the concentration value ranges from [-100, 100], and the focus value ranges from [0, 100]. Generally, the focus value is calculated based on the amplitude of the alpha brain wave alone.

[0182] 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.

[0183] 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.

[0184] like Figure 5 As shown, the EEG headband worn at PF2 on the forehead of the human body collects EEG signals, and the collected EEG signals at least include: brain wave signals and eye wave signals. Figure 5It is defined in the specification that the EEG headband is a single-channel EEG headband. In the actual implementation process, the EEG headband can also be a multi-channel EEG headband. The original signals collected by the EEG headband are transmitted to the mobile phone via Bluetooth. The mobile phone can process the application (Application, App) that generates control instructions based on EEG signals. After receiving the original signal transmitted by Bluetooth of the EEG headband, it performs communication analysis and processes it based on the processing algorithm to separate the alpha brain waves, beta brain waves and eye waves in the EEG. Finally, based on the control algorithm, the concentration value is calculated to obtain the peak value and trough value of the curve corresponding to the concentration value. The peak value and trough value based on the concentration value are used to generate two control instructions respectively; the eye waves are used to generate another control instruction. For example, the number of eye movements can be extracted based on the eye waves, and then whether to generate a control instruction is controlled based on the number of eye movements.

[0185] For specific operation procedures, please refer to Figure 6 As shown, firstly, the single-channel original EEG signal is analyzed, and four different brain waves and one eye wave are separated by Fourier transform;

[0186] Then, the concentration value is processed into a real-time effective concentration value according to the concentration value algorithm, and the peak characteristics of the eye wave are extracted according to the eye electrogram algorithm. That is, the eye electrogram feature here is determined according to the peak of the eye wave.

[0187] Finally, a comprehensive judgment is made based on the corresponding threshold, the obtained concentration value and the electrical detection characteristics, and a control instruction is generated based on the judgment result.

[0188] When the electrooculogram feature is greater than a certain threshold A, the first command (command-1) is executed.

[0189] When a peak value of the concentration value is greater than the threshold value B, the second signal instruction (command-2) is executed.

[0190] When a certain trough value of the concentration value is less than the threshold C, the third instruction (command-3) is executed;

[0191] 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 preset time length corresponding to the third type of control command mentioned above.

[0192] The first instruction here is a type of the aforementioned second type of control instruction; the second instruction and the third instruction here are both the aforementioned first type of control instruction. The fourth instruction here is the aforementioned third type of control instruction.

[0193] When calculating the peak and trough values ​​of the concentration value, it is generally necessary to take the first three concentration values. When the signs of the slopes between the two values ​​are opposite, an extreme point appears, and the middle point is used as the judgment point of the threshold value. This threshold value can be initialized and calibrated according to the characteristics of the EEG signals of different users. For example, the threshold value is determined based on the historical EEG signals of the target user and the control behavior of the electronic device. The threshold value here may include: the aforementioned first threshold value and / or the second threshold value.
