Detailed Description

With the emphasis of a user on personal privacy and data security, many electronic devices with a display function are provided with a screen locking function, so that the user can conveniently lock the screen of the electronic device when leaving the electronic device to prevent the electronic device operated by others from peeping the user privacy or stealing data.

For example, in the case of an electronic device being a computer, the computer is generally provided with a function of locking a screen in order to protect the privacy of a user during the use of the computer. Under the condition that the computer has the function of locking the screen, the user can lock the screen of the computer before leaving the computer, so that the user privacy or user data can be prevented from being peeped by the computer operated by other people.

The user can lock the screen of the computer in a manual locking mode. For example, the user may manually lock the screen by a set shortcut key. For example, a combination key Win + L can be set as a shortcut key to lock the screen of the computer, and when a user needs to leave the computer, the screen can be locked by pressing the combination key Win + L. Or, the user can also set the computer to automatically lock the screen. For example, a user can set a screen locking time in a computer system setting, and when the non-operation time of the user exceeds the screen locking time set by the user, the computer can automatically lock the screen.

After the computer screen is locked, the user can unlock the screen through a preset verification mode so as to continue using the computer. For example, the preset authentication manner may be password authentication, and the user may set a password for screen unlocking when the function of locking the screen is turned on. When the user needs to unlock the screen, the user can manually input the password so that the computer can verify the password input by the user, and when the password is verified, the computer can unlock the screen to return to the interface before the screen is locked so that the user can continue to use the computer. For another example, the preset authentication manner may be fingerprint authentication, and the user may set fingerprint information for unlocking the screen when the function of locking the screen is turned on. When a user needs to unlock the screen, the user can touch the identification area of the fingerprint identification module by a finger (for example, the user touches the identification area of the fingerprint identification module on the power key of the computer by the finger) so that the computer collects fingerprint information of the user and verifies the fingerprint information. When the fingerprint verification is passed, the computer can unlock the screen to return to the interface before the screen is locked, so that the user can continue to use the computer. For another example, the preset verification mode may be face verification, and the user may set face information for unlocking the screen when the function of locking the screen is turned on. When the user needs to unlock the screen, the face of the user can face the camera of the computer, so that the computer can collect the face information of the user and verify the face information. When the face verification passes, the computer can unlock the screen to return to the interface before the screen is locked, so that the user can continue to use the computer.

From the above, it can be seen that, during the process of using an electronic device (such as a computer) by a user, the screen of the electronic device needs to be locked and unlocked manually. The electronic device cannot automatically lock or unlock the screen, and cannot provide convenient screen locking and unlocking experience for the user.

In order to solve the above problem, embodiments of the present application provide a method for locking and unlocking a screen, where the method can be applied to a scenario where a screen of an electronic device is locked (or referred to as a locked electronic device) when a user wears a wearable device far away from the electronic device, and a screen of the electronic device is unlocked (or referred to as an unlocked electronic device) when the user wears the wearable device close to the electronic device. For example, taking the electronic device as a computer and the wearable device as a smart watch as an example, as shown in (a) of fig. 1, the computer is currently in a screen-unlocked state, and when the user wears the smart watch and is far away from the electronic device, as shown in (b) of fig. 1, the computer performs screen locking to prevent others from operating the electronic device to peep the privacy of the user or steal user data. Alternatively, as shown in fig. 2 (a), the computer is currently in the screen-locked state, and when the user wears the smart watch and approaches the electronic device, as shown in fig. 2 (b), the electronic device performs screen unlocking to allow the user to continue using the computer. The method can comprise the following steps: the electronic device calculates the distance between the electronic device and the wearable device, acquires the motion data of the user in the wearable device, and then performs screen locking or screen unlocking operation according to the motion data and the distance between the wearable device and the electronic device.

Thus, when the electronic device is in the screen unlocking state, the electronic device can automatically perform screen locking when the user wears the wearable device and leaves the electronic device. When the electronic device is in the screen locking state, the electronic device can automatically perform screen unlocking when the user wears the wearable device and returns to the front of the electronic device. Thereby providing a more convenient screen locking and unlocking experience for the user. Moreover, the electronic device can judge whether the user wears the wearable device to move according to the acquired motion data of the user, so that the situation that the electronic device misjudges to lock or unlock the screen when the user does not wear the wearable device but the wearable device is translated is avoided, and the reliability of the electronic device in realizing automatic screen locking or unlocking through the method is improved.

For example, taking the example of communication connection between the computer and the smart watch through bluetooth, the distance between the computer and the smart watch can be calculated through the following formula:

d＝10 ^{(abs(RSSI)-A)/(10n)}

wherein abs (RSSI) is the absolute value of RSSI, a is the RSSI at a distance of 1 meter between the transmitting end (e.g., smart watch) and the receiving end (e.g., computer), and n is the environmental attenuation factor. In the embodiment of the present application, the values of a and n are preset fixed values, and may be obtained according to experimental tests or empirical values, which is not limited herein.

Optionally, the computer may perform S402 if it is determined that it is logged in with the smart watch with the account. Therefore, the computer can verify the safety of the intelligent watch so as to prevent other users from locking or unlocking the screen after the intelligent watch is connected with the computer of the user.

When the computer determines that the distance between the computer and the smart watch is smaller than the first threshold value or larger than the second threshold value, the computer may perform the following S403. Optionally, in some other embodiments, if the distance between the computer and the smart watch is equal to the first threshold or equal to the second threshold, the computer may also perform the following step S403. The first threshold value and the second threshold value can be set according to actual conditions, so that the distance between the computer and the intelligent watch can be indicated to be closer to the computer when the distance is smaller than the first threshold value (namely, the intelligent watch is near the computer), and the distance between the computer and the intelligent watch can be indicated to be farther from the computer when the distance is larger than the second threshold value (namely, the intelligent watch is far away from the computer, or the intelligent watch is not near the computer). For example, the first threshold may be set to 1 meter, the second threshold to 3 meters, and so on. That is, when the distance between the computer and the smart watch determined by the computer is less than 1 meter, it indicates that the smart watch is near the computer, and when the distance between the computer and the smart watch determined by the computer is greater than 3 meters, it indicates that the smart watch is far away from the computer.

S403, the computer obtains motion data of the user in the intelligent watch.

As an example, the computer may obtain the exercise data of the user in the smart watch by sending a request for obtaining the exercise data to the smart watch, and the smart watch may send the exercise data of the user to the computer after receiving the request sent by the computer. Of course, in some other possible embodiments, the computer may also obtain the exercise data of the user in other manners, for example, the computer directly queries the smart watch to obtain the exercise data, and the like.

The motion data of the user may include parameters related to the motion of the user, such as the number of motion steps, the step frequency, the walking distance, and the like of the user. The computer can judge whether the user wears the sports watch to move according to the acquired sports data of the user. So as to be convenient for executing the corresponding screen locking or unlocking operation subsequently according to the distance between the computer and the intelligent watch determined in the step S402.

S404, the computer performs screen locking or screen unlocking operation according to the motion data and the distance between the computer and the intelligent watch.

In some possible embodiments, whether screen locking or screen unlocking is required or not can be judged according to the motion data and the distance between the computer and the intelligent watch, and corresponding operation is executed. That is, when the distance between the computer and the smart watch is greater than the second threshold, it indicates that the smart watch is away from the computer. Then, the computer can determine whether the user wears the smart watch to move by combining with whether the acquired motion data of the user changes so as to further determine whether screen locking is needed. When the distance between the computer and the intelligent watch is smaller than a first threshold value, the intelligent watch is near the computer. Then, the computer can determine whether the user wears the smart watch to move by combining with whether the acquired motion data of the user changes or not so as to further determine whether the screen needs to be unlocked or not.

For example, taking the exercise data as the exercise steps of the user, when the distance between the computer and the smart watch determined by the computer is greater than the second threshold, it indicates that the smart watch is far away from the computer. At this time, if the obtained exercise step number of the user is increased compared with the exercise step number of the user obtained last time by the computer (that is, when the computer determines that the distance between the computer and the smart watch is smaller than the first threshold value, the exercise step number of the user obtained by the computer is greater than or equal to a preset value (or referred to as a third threshold value), it is indicated that the distance between the smart watch and the computer is greater than the second threshold value because the user wears the smart watch and moves to a position far away from the computer. At this time, if the computer is in the state of screen unlocking, the computer can execute the operation of screen locking. That is, under the condition that the computer is in the screen unlocking state, when the computer determines that the distance between the computer and the smart watch is greater than the second threshold, the computer may obtain the exercise step number of the user, and if the exercise step number of the user is increased by at least a preset value compared with the exercise step number obtained last time, the computer may perform the screen locking operation. So, can avoid the user not to wear intelligent wrist-watch and place intelligent wrist-watch when keeping away from the position normal use computer of computer (if, place when charging in the position of keeping away from the computer), the computer only just carries out the screen locking operation according to its distance between the intelligent wrist-watch far away and influences the condition that the user normally used.

And when the distance between the computer and the intelligent watch is smaller than a first threshold value, the intelligent watch is near the computer. At this time, if the obtained exercise step number of the user is increased compared with the exercise step number of the user obtained last time by the computer (that is, when the computer determines that the distance between the computer and the smart watch is greater than the second threshold value, the exercise step number of the user obtained by the computer is greater than or equal to a preset value (or referred to as a third threshold value), it is indicated that the distance between the smart watch and the computer is smaller than the first threshold value because the user wears the smart watch and moves to a position near the computer. At this time, if the computer is in the state of screen locking, the computer can execute the operation of screen unlocking. That is, under the condition that the computer is in the screen-locked state, when the computer determines that the distance between the computer and the smart watch is smaller than the first threshold, the computer may acquire the exercise step number of the user, and if the exercise step number of the user is increased by at least a preset value compared with the exercise step number acquired last time, the computer may perform the screen-unlocking operation. Therefore, the situation that the computer screen is unlocked mistakenly due to the fact that the computer only executes screen unlocking operation according to the fact that the distance between the computer and the intelligent watch is short when the user does not wear the intelligent watch to place the intelligent watch at the position near the computer to manually lock the computer screen can be avoided. That is, as shown in fig. 5, when the user does not wear the smart watch and places the smart watch at a position near the computer, and then manually locks the computer screen, the computer will not unlock the screen.

It should be noted that the preset value in the above example may be set according to an empirical value, for example, the preset value in the above example is set to 50 steps, or may be set according to an average value of the number of moving steps when most users (for example, all test users) move a distance corresponding to a difference value between the second threshold and the first threshold, and the like, which is not limited herein.

Optionally, in this embodiment of the application, based on the method shown in fig. 4, after S402, the computer may further obtain biometric data of the user in the smart watch, so as to determine whether the user wears the watch according to the biometric data. For example, taking the biometric data as the heart rate data, when the computer determines the distance between the computer and the smart watch, and the distance is smaller than the first threshold or larger than the second threshold, the computer may obtain the heart rate data of the user in the smart watch, and when the heart rate data of the user is zero, it indicates that the user does not wear the smart watch, and at this time, the computer may not perform S403 and S404, that is, at this time, the computer does not perform automatic screen locking or unlocking. When the heart rate data of the user is not zero, the user wears the smart watch, and at the moment, the computer can execute the operations of S403 and S404 again to lock or unlock the screen. Therefore, the problem that when a user does not wear the intelligent watch, other users move the intelligent watch to lock or unlock the automatic screen of the computer to cause interference and cause misjudgment of the computer can be avoided.

Alternatively, in this embodiment of the application, based on the method shown in fig. 4, the determination of the distance between the computer and the smart watch in S402 may be a real-time calculation determination (i.e., a real-time detection of the distance between the computer and the smart watch). When the distance between the smart watch and the computer is detected to be the first distance, the computer may determine that the smart watch is close to the computer, and when the distance between the smart watch and the computer is detected to be the first threshold (i.e., the first threshold in the above example), the computer performs steps S403 and S404. Wherein the first distance is greater than a first threshold. When the distance between the smart watch and the computer is detected to be the second distance, the computer may determine that the smart watch is far away from the computer, and when the distance between the smart watch and the computer is detected to be the second threshold (i.e., the second threshold in the above example), the computer performs steps S403 and S404. Therefore, whether the intelligent watch moves or not can be further determined according to the detected distance change between the intelligent watch and the computer, and the misjudgment condition that the computer locks or unlocks the screen only according to the fact that the distance between the intelligent watch and the computer is far or near when the intelligent watch is far away from or near the computer but not moved is avoided.

In this embodiment, based on the foregoing embodiment, after determining the distance between the electronic device and the wearable device, the electronic device may further directly acquire the motion data of the user in the wearable device without determining the size relationship between the distance and the first threshold and the second threshold, and then perform screen locking according to that the distance between the electronic device and the wearable device is greater than the second threshold and the motion data is changed compared with the motion data acquired last time, and perform screen unlocking according to that the distance between the electronic device and the wearable device is smaller than the first threshold and the motion data is changed compared with the motion data acquired last time.

Optionally, in this embodiment of the application, before the electronic device performs a corresponding screen locking or screen unlocking operation according to the distance between the electronic device and the wearable device and the acquired motion data of the user, the wearable device may further determine whether to establish a communication connection with the electronic device according to the distance between the electronic device and the electronic device, so that the subsequent electronic device acquires the motion data of the user from the wearable device for performing the screen locking or screen unlocking operation.

For example, based on the method shown in fig. 4, in the case that the screen of the electronic device is locked, the wearable device may record the current number of steps (or referred to as a first number of steps) when determining that the distance to the electronic device is a first preset distance, and then record the current number of steps (or referred to as a second number of steps) when determining that the distance to the electronic device is a second preset distance (where the second preset distance is smaller than the first preset distance and is greater than the first threshold in the foregoing embodiment), and if the current number of steps is greater than the first number of steps, that is, when the wearable device determines that the distance to the electronic device is the second preset distance, the number of steps of the user is increased, the wearable device may establish a connection with the electronic device, so that the electronic device may subsequently acquire the motion data of the user. In the case that the screen of the electronic device is unlocked, the wearable device may record the current number of steps (or referred to as the third number of steps) when determining that the distance between the wearable device and the electronic device is the third preset distance, and then record the current number of steps (or referred to as the fourth number of steps) when determining that the distance between the wearable device and the electronic device is the fourth preset distance (where the fourth preset distance is greater than the third preset distance and the second threshold in the foregoing embodiment), and if the fourth number of steps is greater than the third number of steps, that is, when the wearable device determines that the distance between the wearable device and the electronic device is the fourth preset distance, the number of steps of the user increases, the wearable device may disconnect from the electronic device, and the electronic device may start broadcasting. It should be noted that the first preset distance, the second preset distance, the third preset distance, and the fourth preset distance may be set according to actual situations. For example, the first preset distance and the fourth preset distance may be equal and both set to 10 meters, the second preset distance and the third preset distance may be equal and both set to 5 meters, and so on.

For example, taking an electronic device as a computer, a wearable device as a smart watch, and a bluetooth connection between the electronic device and the wearable device as an example, another method for locking and unlocking a screen provided in the embodiment of the present application may include the following S601-S6015.

In the case of the computer screen lock, the computer may perform screen unlocking according to the screen locking and unlocking method, for example, the following S601-S608 may be performed.

S601, under the condition that the computer screen is locked, the computer sends a broadcast signal.

S602, the intelligent watch receives the broadcast signal sent by the computer, and determines the distance between the intelligent watch and the computer according to the signal intensity of the broadcast signal.

Illustratively, the signal strength of the broadcast signal may be represented by RSSI. Accordingly, the distance between the smart watch and the computer may be calculated according to the RSSI of the broadcast signal (refer to the description of the related embodiment in S402 in the method shown in fig. 4, which is not described herein again).

And S603, when the intelligent watch determines that the distance between the intelligent watch and the computer is the first preset distance, the intelligent watch records the step data (or called as the first step data) of the current user.

For example, taking the first preset distance as 10 meters as an example, as shown in fig. 6 (a), the distance between the smart watch and the computer is 10 meters, and at this time, the smart watch may record the step number data of the current user.

And S604, when the intelligent watch determines that the distance between the intelligent watch and the computer is the second preset distance, the intelligent watch records the step data (or called as second step data) of the current user.

For example, taking the second preset distance as 5 meters as an example, as shown in (b) of fig. 6, the smart watch approaches the computer, and the distance between the smart watch and the computer is 5 meters, at this time, the smart watch may record the step data of the current user.

And S605, when the intelligent watch determines that the second step data is larger than the first step data, the intelligent watch establishes communication connection (or called short-distance wireless communication connection) with the computer according to the broadcast signal sent by the computer.

For example, as shown in fig. 6 (b), when the smart watch determines that the second step data is greater than the first step data, the smart watch may establish a communication connection with the computer at a second predetermined distance (e.g., 5 meters) from the computer.

S606, the computer receives the short-distance wireless communication signal sent by the intelligent watch, and the distance between the computer and the intelligent watch is determined according to the signal intensity of the short-distance wireless communication signal.

For example, the signal strength of the short-range wireless communication signal may be represented by RSSI, and accordingly, the distance between the computer and the smart watch may be calculated according to the RSSI of the short-range wireless communication signal (refer to the description of the related embodiment in S402 in the method shown in fig. 4, which is not described herein again).

S607, when the computer determines that the distance between the computer and the smart watch is less than or equal to the first threshold (i.e. the first threshold in the method shown in fig. 4), the computer obtains the first exercise data of the user from the smart watch.

For example, taking the first threshold as 1 meter as an example, as shown in (c) of fig. 6, the smart watch continues to approach the computer, and the distance between the computer and the smart watch is 1 meter, at which time the computer may obtain the first exercise data of the user from the smart watch.

Specifically, the related description in S403 of the method shown in fig. 4 can be referred to for the computer to obtain the motion data (e.g., the first motion data) of the user, which is not repeated herein.

And S608, when the computer determines that the first motion data (such as the number of motion steps) of the user is increased compared with the motion data (such as the number of motion steps) of the user obtained last time, and the increased value is greater than or equal to a preset value, performing screen unlocking operation.

The specific implementation of the operation of unlocking the screen by the computer according to the acquired motion data of the user and the distance between the computer and the smart watch may refer to the related description in S404 in the method shown in fig. 4, which is not described herein again.

For example, as shown in fig. 6 (c), when the computer determines that the first exercise data (e.g., exercise step number) of the user is increased compared to the last acquired exercise data (e.g., exercise step number) of the user and the increased value is greater than or equal to a preset value (e.g., when the exercise data is the exercise step number, the preset value is 50 steps), the computer may perform a screen unlocking operation, i.e., unlock the screen.

Optionally, in this embodiment of the application, after S608, the computer may further send an indication that the screen is unlocked (e.g., the first indication) to the smart watch, and when the smart watch receives the indication, the smart watch may display a prompt interface (or referred to as the first interface) for instructing the user to unlock the screen. For example, the first interface may be as shown in fig. 7, and the first interface may include a prompt of "the computer is unlocked". Or, when the smart watch receives the indication information, vibration feedback can be performed.

Optionally, in this embodiment of the application, when the computer performs the screen unlocking operation in S608, the computer may further turn on the camera to detect whether there is another user (i.e., a non-authenticated user in the login information in the computer) before the computer, and if there is a non-authenticated user, the computer does not perform the unlocking operation. That is, when the computer starts the camera to detect whether a non-verified user exists before the computer, if not, the computer performs screen unlocking operation.

Under the condition that the computer screen is unlocked and short-distance wireless communication connection is established with the smart watch, the computer can perform screen locking according to the screen locking and unlocking method, for example, the following S609-S6015 can be performed.

S609, in a case that the computer screen is unlocked (for example, as shown in (c) of fig. 6), the computer receives the short-distance wireless communication signal sent by the smart watch, and determines a distance between the computer and the smart watch according to a signal strength of the short-distance wireless communication signal.

For example, the signal strength of the short-range wireless communication signal may be represented by RSSI, and accordingly, the distance between the computer and the smart watch may be calculated according to the RSSI of the short-range wireless communication signal (for example, refer to the description of the related embodiment in S402 in the method shown in fig. 4, which is not repeated herein).

S6010, when the computer determines that the distance between the computer and the smart watch is greater than or equal to the second threshold (i.e., the second threshold in the method shown in fig. 4), the computer acquires second motion data of the user from the smart watch.

For example, taking the second threshold as 3 meters as an example, as shown in (a) of fig. 8, the smart watch moves away from the computer, and when the distance between the computer and the smart watch is 3 meters, the computer may obtain the second motion data of the user from the smart watch.

For the specific reference to the related description in S403 of the method shown in fig. 4, the computer may obtain the motion data (e.g., the second motion data) of the user, which is not described herein again.

S6011, when the computer determines that the obtained second motion data (such as the number of motion steps) of the user is increased compared with the last obtained motion data (such as the number of motion steps) of the user, and the increased value is greater than or equal to a preset value, performing a screen locking operation.

For example, as shown in fig. 8 (a), when the computer determines that the second exercise data (e.g., exercise step number) of the user is increased compared to the last exercise data (e.g., the first exercise data acquired in S607) of the user and the increased value is greater than or equal to the preset value (e.g., the preset value is 50 steps when the exercise data is the exercise step number), the computer may perform a screen lock operation, i.e., the computer locks the screen.

Optionally, in this embodiment of the application, after S6011, the computer may further send an indication that the screen is locked (e.g., a second indication) to the smart watch, and when the smart watch receives the indication, the smart watch may display a prompt interface (or referred to as a second interface) for indicating that the screen of the computer is locked. For example, the second interface may be as shown in fig. 9, and the second interface may include a prompt of "computer locked". Or, when the smart watch receives the indication information, vibration feedback can be performed.

S6012, the intelligent watch receives the short-distance wireless communication signal sent by the computer, and the distance between the intelligent watch and the computer is determined according to the signal intensity of the short-distance wireless communication signal.

For example, the signal strength of the short-range wireless communication signal may be represented by RSSI, and accordingly, the distance between the smart watch and the computer may be calculated according to the RSSI of the short-range wireless communication signal (for example, refer to the description of the related embodiment in S402 in the method shown in fig. 4, which is not repeated herein).

S6013, when the smart watch determines that the distance between the smart watch and the computer is the third preset distance, the smart watch records step data (or called as third step data) of the current user.

For example, taking the third preset distance equal to the second preset distance as 5 meters as an example, as shown in (b) in fig. 8, the smart watch moves away from the computer, and the distance between the smart watch and the computer is 5 meters, at this time, the smart watch may record the step number data of the current user.

S6014, when the smart watch determines that the distance between the smart watch and the computer is a fourth preset distance, the smart watch records step data (or fourth step data) of the current user.

For example, taking the fourth preset distance equal to the first preset distance of 10 meters as an example, as shown in (c) of fig. 8, the smart watch continues to move away from the computer, and the distance between the smart watch and the computer is 10 meters, at this time, the smart watch may record the step data of the current user.

S6015, when the smart watch determines that the fourth step data is larger than the third step data, the smart watch is disconnected from the computer in a communication mode (or called short-distance wireless communication connection).

For example, as shown in fig. 8 (c), when the smart watch determines that the fourth step data is greater than the third step data, the smart watch may disconnect from the computer in communication at a fourth preset distance (e.g., 10 meters) from the computer.

By adopting the method in the above embodiment, when the electronic device is in the screen unlocking state, the electronic device can automatically perform screen locking when the user wears the wearable device and leaves the electronic device. When the electronic device is in the screen locking state, the electronic device can automatically perform screen unlocking when the user wears the wearable device and returns to the front of the electronic device. Thereby providing a more convenient screen locking and unlocking experience for the user. Moreover, the electronic device can judge whether the user wears the wearable device to move according to the acquired motion data of the user, so that the situation that the electronic device misjudges to lock or unlock the screen when the user does not wear the wearable device but the wearable device is translated is avoided, and the reliability of the electronic device in realizing automatic screen locking or unlocking through the method is improved.

In a possible implementation manner, the electronic device is further configured to receive a short-range wireless communication signal sent by the wearable device and determine a distance between the electronic device and the wearable device according to signal strength of the short-range wireless communication signal, when the screen is unlocked and the wearable device is in short-range wireless communication connection; when the distance between the electronic device and the wearable device is determined to be larger than or equal to a second threshold value, acquiring second motion data of the user from the wearable device; when the acquired second motion data of the user is determined to be increased compared with the motion data of the user acquired last time, and the increased value is greater than or equal to a preset value, performing screen locking operation;

In another possible implementation manner, the electronic device is specifically configured to turn on a camera by the electronic device to detect whether a non-authenticated user exists in front of the electronic device, where the non-authenticated user is an unverified user in login information of the electronic device; and if not, the electronic equipment performs screen unlocking operation.
