[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0034] It should be understood that the terms used in this specification are only for the purpose of describing particular embodiments and are not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0035] The embodiments of the present invention provide an unlocking method, apparatus, and smart wearable device. The unlocking method can be applied to smart wearable devices, such as AR glasses, XR glasses, and other electronic devices.

[0036] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0037] Please refer to FIG. 1 , which is a flow chart of an unlocking method provided by an embodiment of the present invention.

[0038] As shown in FIG1 , the unlocking method includes steps S101 to S104 .

[0039] Step S101: When the smart wearable device is in a wearing state, it responds to an unlock trigger operation to enter an unlock mode and display an unlock interface.

[0040] For example, when a user puts on the smart wearable device, the smart wearable device will be in a wearing state. When the unlock trigger operation of the smart wearable device is triggered, the smart wearable device responds to the unlock trigger operation to enter the unlock mode and displays the unlock interface corresponding to the unlock mode.

[0041] For example, taking the smart wearable device as AR glasses, when the user puts on the AR glasses, the virtual graphical user interface corresponding to the AR glasses is displayed. The user operates the corresponding unlock button in the virtual graphical user interface, and the unlock trigger operation of the AR glasses is triggered. Then the AR glasses respond to the unlock trigger operation to enter the unlock mode and display the unlock interface corresponding to the unlock mode.

[0042] Alternatively, when the user puts on the AR glasses, the unlocking interface corresponding to the AR glasses is directly displayed. When the user clicks the unlocking interface, the unlocking trigger operation of the AR glasses is triggered, and the AR glasses respond to the unlocking triggering operation to enter the unlocking mode.

[0043] Step S102: Acquire motion data of the smart wearable device in the unlock mode.

[0044] For example, when the smart wearable device enters the unlocked mode, when the user moves while wearing the smart wearable device, such as when the user wears AR glasses and the user's head moves, the smart wearable device will collect the motion data corresponding to the smart wearable device in the unlocked mode, and then the smart wearable device obtains the corresponding motion data.

[0045] For example, an inertial measurement sensor is provided in the smart wearable device, and the inertial measurement sensor collects motion data of the smart wearable device when the smart wearable device is in an unlocked mode, thereby obtaining motion data corresponding to the smart wearable device.

[0046] In some embodiments, the process of obtaining the motion data of the smart wearable device in the unlock mode further includes: displaying visual prompt information, where the visual prompt information is used to represent the moving direction corresponding to the motion data.

[0047] For example, when the smart wearable device moves according to the unlocking interface, in order to facilitate the preview of the movement effect of the smart wearable device when it moves, visual prompt information can be displayed during the process of obtaining the motion data of the smart wearable device in the unlocking mode, so as to display the movement direction or movement result corresponding to the motion data, so as to achieve the purpose of assisting unlocking, reduce the number of unlocking failures, and thus achieve the effect of quick unlocking.

[0048] For example, as shown in FIG2 , the displayed visual prompt information is image information. When the user intends to connect two points in the unlocking interface, the unlocking interface displays the unlocking trajectory according to the motion data, as shown by the solid line in FIG2 , and displays the corresponding guidance map under the motion data, as shown by the dotted line in FIG2 . The dotted line is also the visual prompt information, thereby achieving the purpose of prompting the user that “if you continue to move in this direction, you can obtain the unlocking trajectory shown by the dotted line in FIG2 ”.

[0049] Optionally, the visual prompt information can be in the form of image prompts, text prompts, voice prompts, etc. This application does not make any specific restrictions and can be selected according to actual needs.

[0050] Specifically, visual prompt information is displayed during the process of obtaining motion data of a smart wearable device in unlocking mode, and the movement direction or movement result corresponding to the motion data can be displayed, thereby helping the user to quickly unlock the device, reducing the number of unlocking failures, and thus achieving a quick unlocking effect.

[0051] Step S103: Determine an unlocking trajectory according to the motion data.

[0052] Exemplarily, the motion data corresponding to the smart wearable device is converted into an unlocking trajectory, that is, a trajectory is drawn in the unlocking interface according to the motion data, thereby obtaining the unlocking trajectory.

[0053] Optionally, the unlocking trajectory is displayed in real time in the unlocking interface while the unlocking trajectory is obtained.

[0054] Specifically, displaying the unlocking trajectory in real time in the unlocking interface while obtaining the unlocking trajectory can improve user interactivity and usage experience, reduce misoperations, thereby reducing the number of unlocking failures and achieving a quick unlocking effect.

[0055] In some embodiments, when the unlocking interface is a circular pattern, determining the unlocking trajectory based on the motion data includes: obtaining the corresponding stay time of the smart wearable device during the trajectory drawing process based on the motion data; when the stay time is greater than the preset time, obtaining the target stay position corresponding to the stay time; and determining the unlocking trajectory based on the target stay position and the motion data.

[0056] Exemplarily, the unlocking interface is a circular pattern including multiple scales to achieve the angular range of the reminder to move the smart wearable device. The dwell time of the smart wearable device during the trajectory drawing process is determined based on the motion data. When the dwell time is greater than a preset time, the dwell position corresponding to the dwell time is used as the target dwell position. Furthermore, the starting position of the smart wearable device during the trajectory drawing process is determined based on the motion data, and the unlocking trajectory of the smart wearable device is determined based on the starting position and the target dwell position.

[0057] In addition, when determining the unlocking trajectory based on the starting position and the target stop position, there is no restriction on the style of the unlocking trajectory. It is only necessary to ensure that the scale corresponding to the starting position and the scale corresponding to the target stop position do not change.

[0058] For example, if the circular pattern is a 360-degree scale divided into units and the preset time is 2 seconds, the dwell time of the smart wearable device during the trajectory drawing process is obtained based on the motion data. If the dwell time is greater than 2 seconds, the dwell position corresponding to the dwell time is used as the target dwell position. The starting position of the smart wearable device during the trajectory drawing process is determined based on the motion data, and the unlocking trajectory of the smart wearable device is determined based on the starting scale corresponding to the starting position and the ending scale corresponding to the target dwell position.

[0059] Specifically, when the user uses the starting position and the target stop position to determine the unlocking trajectory corresponding to the smart wearable device, it is only necessary to ensure that the scale corresponding to the starting position and the scale corresponding to the target stop position are correct. Therefore, the user is more flexible when drawing the unlocking pattern and can achieve the unlocking effect more quickly.

[0060] In some embodiments, when the unlocking interface is a dot pattern, determining the unlocking trajectory according to the motion data includes: determining a connection relationship between points in the dot pattern according to the motion data; and determining the unlocking trajectory according to the connection relationship.

[0061] Exemplarily, as shown in FIG3 , the unlocking interface is a dot pattern, and the connection relationship between the points in the dot pattern is determined based on the motion data. If the connection relationship includes connection and non-connection, the corresponding points are linearly connected according to the connection relationship, and the connection result is determined as the unlocking trajectory corresponding to the smart wearable device on the unlocking interface.

[0062] For example, as shown in Figure 4, taking the five-point diagram as an example, the dot pattern includes five points, namely, top, bottom, left, right and center. If the center right, the upper right and the upper left are determined to be connected, and the relationship between the remaining points cannot be determined to be a connected relationship in the motion data, then the relationship between the remaining points is defaulted to be an unconnected relationship, and then the corresponding points in the center right, upper right and upper left in the five-point diagram are connected by line segments to obtain the unlocking trajectory corresponding to the smart wearable device on the unlocking interface.

[0063] Optionally, when the unlocking interface is a dot pattern, the number of dots can be a five-dot pattern, a six-dot pattern, a seven-dot pattern, a nine-dot pattern, etc. This application does not impose any specific restrictions on the number of dots in the unlocking interface, and it can be set according to actual needs.

[0064] Specifically, the dot pattern on the unlock interface can create more unlock combinations, increase the difficulty of cracking, and increase the security of the unlock interface. The dot pattern can also be customized into different shapes, bringing users a more diverse and personalized unlocking experience.

[0065] Step S104: Control the smart wearable device to perform a corresponding unlocking operation according to the unlocking trajectory.

[0066] For example, the squares and sums of the Euclidean distance differences between the unlocking trajectory and the corresponding trajectory points in the target trajectory are used to obtain an error value between the unlocking trajectory and the target trajectory. This error value is then compared with a preset error to obtain a comparison result, and the unlock state corresponding to the unlock operation performed on the smart wearable device is determined based on the comparison result. When the error value is less than or equal to the preset error, the unlock state corresponding to the unlock operation performed on the smart wearable device is unlocked successfully. When the error value is greater than the preset error, the unlock state corresponding to the unlock operation performed on the smart wearable device is unlocked unsuccessfully, and the unlock interface continues to be displayed.

[0067] In some embodiments, the smart wearable device is controlled to perform a corresponding unlocking operation according to the unlocking trajectory, as shown in FIG5 , and the specific steps include sub-steps S1041 to S1043.

[0068] Sub-step S1041: Obtain the target trajectory corresponding to the unlocking of the smart wearable device.

[0069] Exemplarily, the target trajectory pre-set in the unlocking interface of the smart wearable device is obtained from the database.

[0070] For example, according to the data code corresponding to the unlocking interface displayed by the smart wearable device, a query is performed from the database according to the data code to obtain the target trajectory corresponding to the unlocking of the smart wearable device.

[0071] In some embodiments, before obtaining the target trajectory corresponding to when the smart wearable device is unlocked, it also includes: responding to the unlock trajectory setting operation and displaying the unlock trajectory setting interface corresponding to the unlock trajectory setting operation; obtaining the movement data corresponding to the smart wearable device on the unlock trajectory setting interface; determining the target trajectory corresponding to the smart wearable device based on the movement data, and storing the target trajectory.

[0072] Exemplarily, when the unlock trajectory setting operation of the smart wearable device is triggered, the smart wearable device responds to the unlock trajectory setting operation and displays the unlock trajectory setting interface corresponding to the unlock trajectory setting operation. The smart wearable device moves in the unlock trajectory setting interface, and then obtains the movement data corresponding to the smart wearable device in the unlock trajectory setting interface, thereby determining the target trajectory corresponding to the smart wearable device based on the movement data, and storing the target trajectory in the database.

[0073] For example, the unlock trajectory setting operation is button A of the smart wearable device. When button A is triggered, the smart wearable device responds to the unlock trajectory setting operation and displays the unlock trajectory setting interface corresponding to the unlock trajectory setting operation. Then, the smart wearable device moves in the unlock trajectory setting interface, and then obtains the target trajectory corresponding to the smart wearable device, maps the target trajectory and the unlock trajectory setting interface, and then stores the mapping result in the database.

[0074] For example, the unlock trajectory setting interface includes interface 1 and interface 2. When the unlock trajectory setting interface is displayed as interface 1, the target trajectory obtained is the target trajectory corresponding to interface 1, and the data structure corresponding to the form {interface 1: target trajectory} is stored in the database; when the unlock trajectory setting interface is displayed as interface 2, the target trajectory obtained is the target trajectory corresponding to interface 2, and the data structure corresponding to the form {interface 2: target trajectory} is stored in the database.

[0075] Optionally, when setting the unlock track interface, you can set one target track or multiple target tracks, that is, you can set multiple passwords in the unlock track setting interface. This application does not specifically limit the number of target tracks, and you can set it according to your actual needs in actual application.

[0076] Sub-step S1042: Match the target trajectory with the unlocking trajectory to obtain a matching result.

[0077] For example, a similarity calculation is performed between the target trajectory and the unlocking trajectory, and a match result is determined based on the similarity calculation result. If the calculated similarity result is greater than or equal to a preset similarity, the match result is a success, and the smart wearable device can be unlocked according to the unlocking trajectory, allowing the user to use the smart wearable device normally. If the similarity result is less than the preset similarity, the match result is a failure, and the user cannot use the smart wearable device normally.

[0078] For example, the similarity between the target trajectory and the unlocking trajectory is calculated using cosine similarity, and the preset similarity is 0.8. When the similarity is greater than or equal to 0.8, the matching result between the target trajectory and the unlocking trajectory is determined to be a successful match; when the similarity is less than 0.8, the matching result between the target trajectory and the unlocking trajectory is determined to be a failed match.

[0079] In some embodiments, when the unlocking interface is a circular pattern, matching the target trajectory with the unlocking trajectory to obtain a matching result includes: determining a target angle corresponding to the target trajectory and obtaining a moving angle corresponding to the unlocking trajectory; calculating an angle difference between the target angle and the moving angle; and determining the matching result based on the angle difference.

[0080] For example, when the unlocking interface is a circular pattern, the angle difference between the target angle corresponding to the target trajectory and the moving angle corresponding to the unlocking trajectory is used. When the angle difference is greater than a preset angle value, the matching result between the target trajectory and the unlocking trajectory is determined to be a matching failure. When the angle difference is less than or equal to the preset angle value, the matching result between the target trajectory and the unlocking trajectory is determined to be a matching success.

[0081] For example, the target angle corresponding to the target trajectory is 30 degrees, and the moving angle corresponding to the unlocking trajectory is 32 degrees. The target angle and the moving angle are then calculated to obtain an angle difference of 2 degrees. When the preset angle value is set to 1 degree, the matching result between the target trajectory and the unlocking trajectory is a matching failure. When the preset angle value is set to 2 degrees, the matching result between the target trajectory and the unlocking trajectory is a matching success.

[0082] Specifically, when determining the matching result based on the angle difference, it is only necessary to use the angle difference between the target angle corresponding to the target trajectory and the moving angle corresponding to the unlocking trajectory, without calculating the error between the trajectories. This simplifies the way of calculating the matching, improves the efficiency of calculating the matching results, and can also achieve the unlocking effect more quickly.

[0083] In some embodiments, when the unlocking interface is a dot pattern, matching the target trajectory with the unlocking trajectory to obtain a matching result includes: determining a target angle and a target direction corresponding to the target trajectory; determining a moving angle and a moving direction corresponding to the unlocking trajectory based on the motion data; calculating a first similarity between the target angle and the moving angle and a second similarity between the target direction and the moving direction; and determining a matching result corresponding to the target trajectory and the unlocking trajectory based on the first similarity and the second similarity.

[0084] Exemplarily, when the unlocking interface is a dot pattern, the target angle and target direction corresponding to the connection relationship between the points in the target trajectory are obtained, and the moving angle and moving direction corresponding to the unlocking trajectory determined according to the motion data are obtained, so that the target angle and the moving angle are subjected to error calculation to obtain a first similarity, and the target direction and the moving direction are subjected to similarity calculation to obtain a second similarity, and then the first similarity and the second similarity are weightedly summed to obtain a fused similarity. When the fused similarity is greater than or equal to the preset similarity, the matching result corresponding to the target trajectory and the unlocking trajectory is a successful match; when the fused similarity is less than the preset similarity, the matching result corresponding to the target trajectory and the unlocking trajectory is a failed match.

[0085] Optionally, the method for obtaining weights in the weighted summation in this application can be set by oneself or based on historical experience. There is no specific restriction in this application and it can be set by oneself according to needs.

[0086] For example, the unlocking interface is a five-point diagram, and the target trajectories are shown in Figure 4 as center-right, top-right, and top-left. Using the right direction of the line containing the left, center, and right points as the x-axis, and the top direction of the line containing the top, center, and bottom points as the x-axis, the target angle for center-right is 0 degrees, and the target direction is from the center point to the right point. The target angle for top-right is 135 degrees, and the target direction is from the right point to the top point. The target angle for top-left is 45 degrees, and the target direction is from the top point to the left point. The movement angle and direction corresponding to the unlocking trajectory are determined based on the motion data. For example, if the unlocking trajectory is center-right, top-right, or top-center, the movement angle for center-right is 0 degrees, and the direction is from the center point to the right point. The movement angle for top-right is 135 degrees, and the direction is from the right point to the top point. The movement angle for top-center is 90 degrees, and the direction is from the top point to the center point. Therefore, similarity is calculated for the center-right in the target trajectory and the center-right in the unlocking trajectory, the top-right in the target trajectory and the center-top in the unlocking trajectory, and the top-left in the target trajectory and the center-right in the unlocking trajectory, respectively.

[0087] The angular similarity between the center right in the target trajectory and the center right in the unlock trajectory is 1, and the directional similarity is 1. The angular similarity between the upper right in the target trajectory and the center upper in the unlock trajectory is 1, and the directional similarity is 1. However, the angular similarity between the upper left in the target trajectory and the center right in the unlock trajectory is 0, and the directional similarity is 0. After fusing the above similarity results, the similarity obtained is 4 / 6=67%. When the preset similarity is set to 90%, it is determined that the matching result corresponding to the target trajectory and the unlock trajectory is a matching failure.

[0088] Specifically, when unlocking an unlock interface with a dot pattern, drawing the dot pattern is faster and more convenient, and the matching result between the target trajectory and the unlocking trajectory is considered and calculated from multiple aspects, thereby improving the accuracy of unlocking.

[0089] Sub-step S1043: controlling the smart wearable device to perform a corresponding unlocking operation according to the matching result.

[0090] For example, when the matching result is a successful match, the unlocking interface of the smart wearable device is successfully unlocked, and the unlocking status obtained after the smart wearable device performs the corresponding unlocking operation is a successful unlocking; when the matching result is a failed match, the unlocking interface of the smart wearable device fails to be unlocked, and the unlocking status obtained after the smart wearable device performs the corresponding unlocking operation is a failed unlocking, and the corresponding unlocking interface of the smart wearable device will continue to be displayed.

[0091] In some embodiments, when the unlocking state obtained after performing the unlocking operation on the smart wearable device according to the unlocking trajectory is unlocking failure, it also includes: obtaining iris information of the target object wearing the smart wearable device; matching the iris information with preset iris information to obtain an iris matching result; and continuing to perform the unlocking operation on the smart wearable device according to the iris matching result.

[0092] For example, when the unlocking trajectory cannot control the smart wearable device to perform the unlocking operation, that is, the unlocking trajectory is input incorrectly and is inconsistent with the target trajectory, the smart wearable device cannot be unlocked.

[0093] For example, when the similarity between the unlock trajectory and the target trajectory is less than a first threshold, the smart wearable device is directly determined to have failed to unlock. When the similarity between the unlock trajectory and the target trajectory is greater than the first threshold but less than a second threshold, the smart wearable device is determined to have failed to unlock. However, at this time, iris information of the target person wearing the smart wearable device can be obtained, and an iris matching result can be determined based on the iris information, thereby continuing to unlock the smart wearable device. When the similarity between the unlock trajectory and the target trajectory is greater than a second threshold, the unlock operation is performed on the smart wearable device, and it is determined that the smart wearable device has been successfully unlocked.

[0094] For example, if the target object is a user wearing a smart wearable device, the user's iris information is obtained; then the similarity between the iris information and the preset iris information is calculated to obtain an iris matching result; when the iris matching result is greater than or equal to the preset similarity value, the unlocking operation on the smart wearable device is continued.

[0095] For example, if the preset iris information includes iris information 1 of user A and the preset similarity value is 90%, then when the target object is user A and iris information 2 is obtained, a similarity calculation is performed on iris information 1 and iris information 2. If the iris match result is 98%, the smart wearable device can be unlocked. If the target object is user B and iris information 3 is obtained, a similarity calculation is performed on iris information 1 and iris information 3. If the iris match result is 20%, the smart wearable device cannot be unlocked, or the smart wearable device can be unlocked but fails.

[0096] Specifically, adding an iris unlocking method between the first threshold and the second threshold can reduce the risk of unlocking failure and enhance user experience.

[0097] Please refer to Figure 6, which is a schematic diagram of a scenario for implementing the unlocking method provided by this embodiment. As shown in Figure 6, when the smart wearable device is in a worn state, it responds to the unlock trigger operation to enter unlock mode and display the unlock interface, and obtains the motion data of the smart wearable device in unlock mode. When the unlock interface is a circular pattern, the corresponding dwell time of the smart wearable device during the trajectory drawing process is obtained based on the motion data. When the dwell time is greater than the preset time, the target dwell position corresponding to the dwell time is obtained, and then the unlocking trajectory is determined based on the target dwell position and the motion data. When the unlock interface is a dotted pattern, the connection relationship between the dots in the dotted pattern is determined based on the motion data, and then the unlocking trajectory is determined based on the connection relationship. The target trajectory corresponding to the unlocking of the smart wearable device is obtained. When the unlocking interface is a circular pattern, the target angle corresponding to the target trajectory and the movement angle corresponding to the unlocking trajectory are determined; the angular difference between the target angle and the movement angle is calculated; and a matching result is determined based on the angular difference. When the unlocking interface is a dotted pattern, the target angle and target direction corresponding to the target trajectory are determined; the movement angle and movement direction corresponding to the unlocking trajectory are determined based on the motion data; a first similarity between the target angle and the movement angle and a second similarity between the target direction and the movement direction are calculated; and a matching result corresponding to the target trajectory and the unlocking trajectory is determined based on the first and second similarities. The smart wearable device is then controlled to perform the corresponding unlocking operation based on the matching result. When the unlocking status obtained after performing the corresponding unlocking operation on the smart wearable device based on the unlocking trajectory is unlock failure, iris information of the target person wearing the smart wearable device is obtained; the iris information is matched with preset iris information to obtain an iris matching result; and the unlocking operation of the smart wearable device is continued based on the iris matching result. This solves the problem in the related art of decrypting the device through password input, which requires the use of an external keyboard or virtual keyboard to enter the password, making the password input process relatively complicated and inconvenient. Improves the convenience and flexibility of decryption for smart wearable devices.

[0098] Please refer to Figure 7. An unlocking device 200 provided by an embodiment of the present invention includes a trigger unlocking module 201, a data acquisition module 202, a trajectory determination module 203, and an unlocking execution module 204.

[0099] In some implementations, during the process of acquiring the motion data of the smart wearable device in the unlocked mode, the data acquisition module 202 further performs: displaying visual prompt information, where the visual prompt information is used to represent the moving direction corresponding to the motion data.

[0100] In some embodiments, when the unlocking interface is a circular pattern, the trajectory determination module 203 performs the following steps during the process of determining the unlocking trajectory according to the motion data:

[0101] Obtaining the corresponding stay time of the smart wearable device during the trajectory drawing process according to the motion data;

[0102] When the stay time is greater than the preset time, the target stay position corresponding to the stay time is obtained;

[0103] The unlocking trajectory is determined according to the target stay position and the motion data.

[0104] In some embodiments, when the unlocking interface is a dot pattern, the trajectory determination module 203 performs the following steps during the process of determining the unlocking trajectory based on the motion data:
