Referring to fig. 2, fig. 2 is a flowchart illustrating an operation control method applied to the electronic device shown in fig. 1A-1D and applied to an electronic device including a brain wave sensor according to an embodiment of the present application, where the operation control method includes:
s201, when the electronic device detects that the electronic device is in a screen locking state and the movement speed is greater than a preset speed threshold value, starting a brain wave control mode of the electronic device;
the electronic device detects a movement speed through the accelerometer, the movement speed is greater than a preset speed threshold value, which can indicate that a user of the electronic device may be running, riding a bicycle, driving a car, or performing extreme challenge and other activities that make it inconvenient for the user to control the electronic device with both hands, and the preset speed threshold value may be an empirical value that is set in the electronic device by a technical developer of the electronic device according to experience before the electronic device leaves a factory.
Wherein, electronic device is in the lock screen state, has further strengthened confirming that the user is inconvenient at present to use both hands to control the cell-phone, for example, when the velocity of motion is greater than preset speed threshold value, the user probably is in under the condition of driving the car, also can be in under the condition of taking the car, wherein, only under the condition of user's driving the car, electronic device probably is in the lock screen state all the time, need start the brain wave control mode, in addition, electronic device is in the lock screen state can do the length of time that electronic device is in the lock screen state is greater than the length of time threshold value of presetting.
Wherein the brain wave control mode is to control the electronic device through the brain waves of a user of the electronic device without controlling the electronic device through a manual operation of the user.
S202, the electronic device acquires a target brain wave signal through the brain wave sensor in the brain wave control mode;
the brain wave is a method for recording brain activity by using electrophysiological indexes, records the electric wave change of the brain in an activity device, and is the overall reflection of the electrophysiological activity of brain nerve cells on the surface of a cerebral cortex or a scalp, so that brain wave signals are collective nerve activity signals generated by the common discharge of a plurality of nerves, and the activity signals of the nerves can be acquired by a brain wave sensor.
And S203, the electronic device controls the electronic device according to the target brain wave signal.
The specific implementation manner of the electronic device controlling the electronic device according to the target electroencephalogram signal may be various, for example, forming an electroencephalogram according to the target electroencephalogram signal, determining an electroencephalogram template matching the electroencephalogram, and controlling the electronic device according to the operation instruction corresponding to the electroencephalogram template; alternatively, the electroencephalogram signal may be subjected to noise reduction, filtering, and other processing to determine a feature value, and an operation command may be determined according to the feature value to control the electronic apparatus, which is not limited herein.
The specific implementation manner of forming the electroencephalogram according to the electroencephalogram signals may be that the electronic device identifies the electroencephalogram information by using a hilbert-Huang Transform (HHT) algorithm, then performs denoising and filtering processing on the electroencephalogram signals, and performs analog-to-digital a/D conversion to obtain standard electroencephalogram signals, and then forms the electroencephalogram according to the standard electroencephalogram signals.
Different electroencephalogram signals correspond to different operation instructions, different electroencephalogram templates or characteristic values are preset in the different operation instructions, and the electroencephalogram templates or the characteristic values are electroencephalograms formed by specific words, phrases and the like of the meditation when a user wants the electronic device to execute a certain operation function, and are further determined. For example, the specific vocabulary for the user to perform the photographing function is "photographing" or "1", and for example, the specific vocabulary for the user to perform the music playing function is "music" or "music", that is, the association relationship between the operation command the user wants the electronic device to perform and the keyword for the meditation cannot be uniquely defined, and the association relationship varies from user to user, so that the electroencephalogram template or feature value formed according to the single time of meditation or the phrase, etc. varies from user to user.
Wherein the operation that the target brain wave signal can control the electronic device to execute at least comprises any one of the following operations: audio playing, navigation application starting, video playing, photographing, unlocking, quick charging, album displaying, game starting, screen adjusting (including interface adjusting, screen locking and magazine adjusting, wallpaper changing), payment, working mode adjusting, telephone calling and answering, application starting, searching and the like, wherein the only limitation is not required.
It can be seen that, in the embodiment of the present application, the electronic device starts the brain wave control mode of the electronic device when detecting that the electronic device is in the screen locking state and the moving speed is greater than the preset speed threshold, collects a target brain wave signal through the brain wave sensor in the brain wave control mode, and controls the electronic device according to the target brain wave signal. Therefore, the electronic device can indicate that the user is possibly in the situation that the user is inconvenient to operate the electronic device by using both hands such as driving under the current situation when the electronic device detects that the movement speed is larger than the preset speed threshold value and is in the screen locking state, and the mode of controlling the electronic device by the brain waves is started under the situation, so that the control method for the electronic device without the operation of both hands in the movement process is favorably realized, and the safety and the convenience for controlling the electronic device in the movement process are improved.
In one possible example, the acquiring of the target brain wave signals by the brain wave sensor includes:
determining a brain wave signal with a distance from the electronic device smaller than a preset distance threshold value as the target brain wave signal;
and acquiring the target brain wave signal through the brain wave sensor.
The electronic device may determine, through the distance sensor or the camera, a user whose distance from the electronic device is less than a preset distance threshold, and generally, the user whose distance from the electronic device is less than the preset distance is a main user of the electronic device.
The electronic device can also judge the brain wave signal with the distance from the electronic device smaller than a preset distance threshold value by judging the strength of the brain wave signal, and when the brain wave signal is weaker, the attenuation of the brain wave signal is more, and the distance from the position where the brain wave signal is sent to the electronic device is farther.
As can be seen, in this example, the electronic device determines the target brain wave signal by determining the brain wave signal whose distance from the electronic device is smaller than the preset distance threshold, instead of acquiring a plurality of brain wave signals or acquiring the brain wave signals of the non-subject user when the user is in a multi-user environment, which is beneficial to improving the accuracy of brain wave acquisition, avoiding the situation that the non-subject user controls the electronic device, and improving the safety of the electronic device.
In one possible example, the controlling the electronic device according to the target brain wave signal includes:
when a target operation instruction matched with the target brain wave signal is detected, executing unlocking operation aiming at a touch display screen of the electronic device;
and when the unlocking operation is finished, controlling the electronic device according to the target operation instruction.
When a target operation instruction matched with the target brain wave signal is detected, the target brain wave signal can be determined to be the brain wave signal of the user, and the target operation instruction can be any operation instruction.
It can be seen that, in this example, when the electronic device detects a matched target operation instruction, the user himself is ensured and an operation control instruction is determined at the same time, the unlocking operation is directly performed, and then the target operation instruction is performed, without detecting a brain wave signal matched with the unlocking operation first, unlocking is performed, and then a brain wave signal matched with an operation that the user wants to perform is detected, so that the electronic device is controlled, and the operation control speed and the operation control convenience are improved while the safety of the electronic device is ensured.
In this possible example, the detecting of the target operation instruction matching with the target brain wave signal includes:
determining a target operation instruction set in a plurality of operation instruction sets matched with the movement speed, wherein the operation instruction set comprises a corresponding relation between a plurality of operation instructions and an electroencephalogram template;
when the electroencephalogram formed by the target electroencephalogram signal is detected to be matched with the electroencephalogram template of any one operation instruction in the target operation instruction set, determining the operation instruction matched with the target electroencephalogram signal as the target operation instruction.
The electronic device may include a plurality of operation instruction sets, wherein different operation instruction sets in the plurality of operation instruction sets correspond to different movement speed ranges, types and numbers of the operation instructions included in the plurality of operation instruction sets may be the same or different, and electroencephalogram templates corresponding to the same operation instructions in different operation instruction sets are different.
As can be seen, in this example, the electronic device first selects a target operation instruction set matched with the current movement speed, that is, determines an electroencephalogram template set that needs to be subjected to matching operation, and then determines a target operation instruction by matching, instead of neglecting different actions of the movement speed on the user, and the same additional operation instruction set is used at all movement speeds, which is beneficial to improving the accuracy of operation control of the electronic device.
In this possible example, the method further comprises: acquiring reference brain wave signals when a user meditates different operation instructions under different movement speed ranges of the electronic device according to historical operation records in a preset time period;
forming electroencephalogram templates corresponding to different operation instructions according to the reference brain wave signals;
forming a plurality of operation instruction sets by using electroencephalogram templates corresponding to the different operation instructions of the electronic device in different movement speed ranges, wherein the movement speed ranges of the electronic device corresponding to any two electroencephalogram templates in each operation instruction set are the same.
