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.

The event to be unlocked may be, for example, an event to be unlocked on a desktop of the mobile terminal, an event to be unlocked in an application, an event to be unlocked in a file, an event to be unlocked in a payment, and the like, which is not limited herein. The event to be unlocked on the desktop refers to an event to be unlocked for locking the screen desktop, the event to be unlocked for applying refers to an event to be unlocked for a specific operation of applying, such as application starting, application deleting and the like, the event to be unlocked for a file refers to an event to be unlocked for a file, such as an event to be unlocked for a target file, and the event to be unlocked for paying refers to an event to be unlocked for paying a scene, such as an event to be unlocked for paying a scene of applying, such as payment treasure, WeChat and the like.

S202, the electronic device determines a target distance parameter between a user and the electronic device according to the target brain wave signal;

the implementation manner of determining, by the electronic device, the target distance parameter between the user and the electronic device through the brain wave signal may be various, for example, the target distance parameter may be determined according to the signal strength of the brain wave, or the distance parameter corresponding to the matched brain wave template may be determined as the target distance parameter according to matching between the brain wave signal template and a preset brain wave signal template, which is not limited herein.

The target distance parameter is a linear distance between a user and the electronic device, and the target distance parameter may be, for example, 1m, 50cm, or the like.

S203, the electronic device controls an unlocking strategy of the electronic device according to the target distance parameter so as to execute unlocking operation.

Wherein different target distance parameters use different unlocking strategies, for example, when the target distance parameters are in a first distance range, a fingerprint unlocking strategy may be used; when the target distance parameter is in a second distance range, a face unlocking strategy can be used; when the target distance parameter is within the third distance range, an iris unlocking strategy may be used, which is not limited herein.

The fingerprint unlocking strategy is a strategy for acquiring fingerprint image data of a finger appointed by a user, matching the fingerprint image data with a stored preset fingerprint image template and executing unlocking operation when the matching is successful; the face unlocking strategy is a strategy for acquiring face image data of a user preset area, matching the face image data with a stored preset face image template and executing unlocking operation when matching is successful; the iris unlocking strategy is a strategy of matching acquired iris image data of a user with a stored preset iris image template and executing unlocking operation when matching is successful.

and acquiring the second biological characteristics through the rotary camera.

The electronic device can be provided with a multi-antenna structure, the multi-antenna structure is used for judging the signal strength of the received target brain wave signals in different directions, the direction with the strongest signal strength is determined to be the direction of the user, and then the relative position of the user and the electronic device is determined; or the frequency band used by the brain wave signal may be different from other received signals, and the direction of the transmission power of the acquired brain wave signal is determined according to the frequency band, so as to determine the relative position between the user and the electronic device, which is not limited herein.

For example, the electronic device is currently in a remote photographing mode, a screen locking event occurs in the photographing process, the user is located at a remote position to wait for photographing, if the user runs and unlocks, the electronic device can determine the relative position of the user and the electronic device by acquiring brain wave signals of the user, and the electronic device transfers the rotary camera to an angle corresponding to the relative position to acquire the face characteristic or iris characteristic of the user, so as to execute the unlocking event and then perform remote photographing.

Therefore, in this example, when the target distance parameter is greater than the preset distance threshold, the electronic device determines the relative position between the user and the electronic device through the target brain wave signal, and further adjusts the angle of the rotary camera, so that the situation that the face feature or the iris feature cannot be accurately acquired during remote unlocking is avoided, and convenience of remote unlocking and accuracy of acquiring the face feature or the iris feature data are improved.

In one possible example, the determining a target distance parameter between the user and the electronic device according to the target brain wave signal includes:

selecting a target mapping relation between brain wave signal intensity and distance parameters according to the environment parameters;

determining a target signal strength of the target brain wave signal;

and inquiring the target mapping relation between the brain wave signal strength and the distance parameter by taking the target signal strength as an inquiry identifier, and determining the target distance parameter corresponding to the target signal strength.

The emotional states of the users may be different under different temperature parameters and sound parameters, and are generic to a series of subjective cognitive experiences and psychological and physiological states generated by a plurality of feelings, ideas and behaviors comprehensively. For example, a hot weather and noisy sound environment may result in a fussy mood for the user, while a cool weather and quiet sound environment may result in a relaxed, steady emotional state for the user.

Different emotional states are different from each other in the active layer of the brain of the user, so that the signal intensities of the brain wave signals acquired by the electronic device for the same keyword are different in different emotional states, and therefore, the mapping relationships between the corresponding brain wave signal intensities and the distance parameters are different in different emotional states, i.e., different environmental parameters.

The electronic device may include a plurality of mapping relationships between brain wave signal strengths and distance parameters, each mapping relationship between a brain wave signal strength and a distance parameter corresponds to a different environmental parameter, and the environmental parameter corresponding to the mapping relationship between each brain wave signal strength and a distance parameter may be obtained by the electronic device from a history of brain wave signal strengths of different environmental parameters when a user uses the electronic device, or may be set in the electronic device by a work technician before the electronic device leaves a factory according to an empirical value.

The specific implementation manner of selecting the target mapping relationship between the brain wave signal strength and the distance parameter according to the environmental parameter may be that the environmental parameter, the mapping relationship between the brain wave signal strength and the distance parameter are preset in the electronic device, the target mapping relationship between the brain wave signal strength and the distance parameter is determined according to the environmental parameter, or the interference of the environment on the brain wave signal strength of the user is determined according to the environmental parameter, and the accurate target mapping relationship between the brain wave signal strength and the distance parameter is determined according to the interference.

Therefore, in this example, the electronic device determines an accurate target mapping relationship between the brain wave signal strength and the distance parameter by acquiring the environmental parameters, and adapts different target mapping relationships to different environmental parameters, thereby facilitating improvement of the accuracy of the target distance parameter.

In this possible example, the selecting the target mapping relationship of the brain wave signal strength and the distance parameter according to the environment parameter includes:

determining the environmental noise level according to the environmental parameters;

determining a standard range of brain wave signal intensity matched with the environmental noise level according to a historical record associated with the brain wave signal of the user within a preset time period;

and acquiring a target mapping relation between the brain wave signal strength and the distance parameter corresponding to the standard range.

The noise level can be 1 level, 2 level, 3 level and the like, and is not limited herein, each noise level corresponds to a noise value range, different environmental parameters correspond to different environmental noise levels, the temperature and the sound belong to the noise range, the electronic device can determine the noise value range according to different ratios of the temperature and the sound to the noise, the temperature value and the sound decibel, and the amount of money determines the environmental noise level.

The historical records include brain wave signal strength, time period, sound decibel, temperature value and the like, and are not limited herein.

The standard range is the range of the brain wave signal intensity in a plurality of historical records of which the time period is the same as that of the current time period, the sound decibel range is the same as that of the current time period and the temperature numerical range is the same as that of the historical records, and the standard range can be the average range of the brain wave signal intensity values in the plurality of historical records or the range between the maximum value and the minimum value.

The standard ranges of the brain wave signal intensities of the users are different, and the standard ranges correspond to different mapping relationships between the brain wave signal intensities and the distance parameters, and the target mapping relationship between the brain wave signal intensities and the distance parameters is a corresponding target mapping relationship when the brain wave signal intensities of the users float within the standard ranges.

In this example, it can be seen that the electronic device determines the ambient noise level according to the interference on the user's brain wave signals generated by the ambient parameters, and determines the current time period of the user according to the history, the standard range of the corresponding brain wave signal intensity fluctuation under the condition of the current environmental noise level is beneficial to improving the intelligence of the electronic device, and selects the target mapping relation of the brain wave signal strength and the distance parameter according to the standard range, if the electronic device only comprises a mapping relation between the brain wave signal strength and the distance parameter, which cannot correspond to all conditions of the user, the brain wave signal range of the user does not always fluctuate in a range, therefore, the electronic device is favorable for improving the adaptability of the mapping relation and the accuracy of determining the distance parameter according to the standard range of the current brain wave signal intensity of the user, and further improving the reasonability of the setting of the unlocking strategy.
