All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The information unlocking method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

An embodiment of the present application provides an information unlocking system, as shown in fig. 1, which is a schematic diagram of an architecture of an optional information unlocking system, and includes a first device 201 and a second device 202.

The first device 201 comprises a processor, a memory and a program or instructions stored on the memory and executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the information unlocking method according to the first aspect; the second device 202 comprises a spatial motion sensor for detecting a motion parameter.

The first device 201 may pair and communicate with the second device 202 in a wired or wireless manner. For example, the pairing relationship and the communication connection are established through communication methods such as bluetooth, infrared, wireless WLAN and the like. Thus, the first device 201 and the second device 202 can transmit data after establishing the communication connection relationship. The communication method used for establishing the pairing relationship may be different from the communication method used for establishing the communication connection.

The information unlocking method provided by the embodiment of the application can be applied to the first device 201 and executed by the first device 201.

As an example, the memory of the first device 201 stores instructions, and the instructions are executed by the processor to control the first device 201 to execute the information unlocking method provided in the embodiment of the present application. The first device 201 may be an electronic device such as a mobile phone, a tablet computer, an all-in-one machine, a notebook computer, and a smart television, or may also be a head-mounted electronic device, for example, 3D smart glasses, VR glasses, and the like, where the lens may be used as a display screen.

The second device 202 may be an electronic device configured with a spatial motion sensor. Based on the motion parameters acquired by the spatial motion sensor, a trajectory of the second device 202 moving in space may be determined. The spatial motion sensor may include a gravitational acceleration sensor, a gyroscope, a geomagnetic sensor, and the like. Illustratively, the second device 202 may be a wearable device, such as a ring, bracelet, or the like, or the second device may be a smart stylus designed in a pen-like fashion.

Fig. 2 is a schematic flow chart of an example implementation of an information unlocking method provided in an embodiment of the present application, including the following steps 101 to 103:

step 101, a first input for requesting unlocking target information is received.

The target information may be any information in the first device. The target information is locked in advance, the content cannot be viewed, and the content can be viewed after the target information is unlocked. For example, the target information may be a system of the first device, such that unlocking the target information corresponds to unlocking the system; or, the target information may be an application installed in the first device, and thus, unlocking the target information is equivalent to unlocking the corresponding application; for another example, the target information may be a folder in the first device, and thus unlocking the target information is equivalent to unlocking the corresponding folder.

The first input is for requesting unlock target information. The receiving may be through an input device configured by the first device or an input device communicatively coupled to the first device. For example, the first device is a notebook computer, the input device may be a keyboard or a touch screen, and the first input may be a click of any keyboard key to trigger a request for unlocking target information; or, the first device is the 3D smart glasses, the input device may be a smart band or a stylus pen paired with the 3D smart glasses, and the first input may be a click on a screen of the smart band or a press of a button on the stylus pen.

And 102, acquiring parameters of a first space track drawn by the motion of a second device paired with the first device in space.

As an alternative embodiment, the second device may be a device for receiving the first input. The second device can communicate with the first device in a wired connection (for example, through serial communication connection such as USB) or wireless connection (for example, through connection such as bluetooth, infrared, WIFI, etc.). The second device may be paired with the first device in advance, for example, the pairing mode may be: installing a driver of the second device, inputting a pairing password provided by the second device by the first device, inputting a pairing password provided by the first device by the second device, pairing the pairing password provided by the first device by the second device, accessing the second device to the wireless local area network provided by the first device, and the like, which cannot be exhausted, and are not described any more.

It should be noted that the second device is an input device provided with a spatial motion sensor. The second device or the first device may determine a trajectory of the second device moving in the space according to the motion parameters acquired by the space motion sensor. The spatial motion sensor may include a gravitational acceleration sensor, a gyroscope, a geomagnetic sensor, and the like. Illustratively, the second device may be a wearable device, such as a ring, bracelet, or the like, or the second device may be a smart stylus designed in a pen-like fashion.

Based on the motion parameters acquired by the second device, parameters of the first spatial trajectory rendered by the second device may be determined. Since the second device can acquire the motion parameters moving in the space, in order to reduce the influence of the misoperation of the user for moving the second device on the drawing, the user can determine when to start the drawing and when to finish the drawing through specified input.

For example, the second device may be a smart stylus pen, and a switch button may be provided on the stylus pen, and each click may be switched between on and off, and after the switch button is turned on, the switch button may be turned on, and after the switch button is turned off, the switch button may be turned off, so that the user may turn on the switch button before each pen starts drawing, and turn off the switch button after each pen draws, thereby preventing useless operations of moving when drawing different sides from being recorded in the first spatial trajectory.

The first spatial trajectory may be any spatial trajectory, for example, the first spatial trajectory may be a movement trajectory caused by a user waving his arm in the air while wearing the second device at a wrist/arm or the like.

In one example, the first spatial trajectory may be an outline of a solid figure in space. For example, the first spatial trajectory may be an outline of a polyhedron, each face of which is a polygon, so that the user may draw the outline of the above-mentioned solid figure in space when drawing the first spatial trajectory. In this case, the parameters of the first spatial trajectory may include data of vertex coordinates and/or side lengths of the first spatial trajectory, and the like.

The specific way to obtain the parameters of the first spatial trajectory may be to determine the parameters of the first spatial trajectory after the first spatial trajectory is generated.

Alternatively, the parameters of the first spatial trajectory may also be determined directly from the motion parameters detected by the spatial motion sensor of the second device configuration. For example, based on the motion parameters detected by the spatial motion sensor configured in the second device, the position parameters of the spatial points of which the deflection angles are greater than the preset threshold are determined, so as to obtain the coordinates of a plurality of inflection points of the first spatial trajectory.

The first spatial trajectory or the parameter of the first spatial trajectory may be generated by the second device directly according to the detected motion parameter, or may be generated by the first device by the second device sending the motion parameter to the first device.

And 103, under the condition that the parameters of the first space track are determined to be matched with the second space track, unlocking the target information.

The second spatial trajectory is a preset trajectory, and may specifically be preset by a user or preset by a factory. In one example, the second spatial trajectory may be an outline of a solid figure, or, for example, a trajectory of a user's wrist/finger/arm movement while performing a pre-specified set of gymnastics, taijiquan, dance, etc., when the second device is worn at the wrist/finger/arm location.

In one example, determining that the parameter of the first spatial trajectory matches the second spatial trajectory may be that the parameter of the first spatial trajectory differs from the corresponding parameter of the second spatial trajectory by less than a specified threshold.

For example, the parameter may be a motion parameter of a spatial trajectory, the motion parameter of the first spatial trajectory may be a motion parameter of a spatial trajectory drawn by the user when unlocking, and the motion parameter of the second spatial trajectory may be a stored motion parameter of a spatial trajectory drawn by the user when setting the key.

For another example, the obtained parameter of the first spatial trajectory may include an inflection point coordinate and/or a side length of the first spatial trajectory; then, determining that the parameters of the first spatial trajectory match the second spatial trajectory may include: and under the condition that the errors of the first space track and the second space track for the inflection point coordinates and/or the side length are determined to be within a first preset range, determining that the parameters of the first space track are matched with the second space track.

In another example, the second spatial trajectory may be an outline of a preset solid figure. After receiving the first input, a part of the preset first stereoscopic graphic may be displayed on the display screen of the first device, so that the user may complement the drawing of the rest part to be the preset first stereoscopic graphic with the displayed part complement. For example, as shown in fig. 3, an exemplary first stereoscopic graphic may display a second stereoscopic graphic as shown in fig. 4 after receiving the first input, the second stereoscopic graphic being a portion of the first stereoscopic graphic shown in fig. 3. If the difference between the parameters of the first spatial trajectory drawn by the user and the solid-line spatial trajectory shown in fig. 5 is smaller than a specified threshold, it indicates that the drawn first spatial trajectory can be combined with the partial solid figure shown in fig. 4 to form the preset solid figure shown in fig. 3, so that it can be determined that the parameters of the first spatial trajectory match the second spatial trajectory.

The following further describes an exemplary information unlocking method provided in the embodiment of the present application.

In an example embodiment, the step 102 of acquiring parameters of a first space track drawn by a second device paired with a first device through motion in a space may include the following steps 1021-1024:

step 1021, receiving the motion parameter sent by the second device.

And step 1022, generating a third space track drawn by the second device through motion in the space according to the motion parameters.

And step 1023, correcting the third space track into a smooth straight line or a smooth curve to obtain the first space track.

Step 1024, determining parameters of the first spatial trajectory.

After the spatial motion sensor of the second device detects the motion parameters, the spatial motion sensor can transmit the motion parameters to the first device in a real-time communication mode. Therefore, the first device receives the motion parameters, and generates a third space track according to the motion parameters. Since the second device may be operated by a person and thus the third spatial trajectory may not be smooth, the third spatial trajectory may be corrected to a smooth straight line or curve in order to generate a smooth graph, and the corrected third spatial trajectory is the first spatial trajectory. Furthermore, parameters of the first spatial trajectory may be determined, which may be pre-specified, for example, the first spatial trajectory may be a stereo, and then the parameters of the first spatial trajectory may be vertex coordinates and/or side lengths of the first spatial trajectory, and so on. By the implementation mode, the operation amount of the second device can be reduced, the calculation cost of the second device can be reduced, and the smooth contour of the first space track can be obtained, so that the first space track which is more suitable for the drawing intention of the user can be obtained.

Further, in step 1022, in order to prevent the user from generating a useless operation of moving the second device when drawing the first spatial trajectory in the third spatial trajectory drawn by the second device in the space according to the motion parameter, whether the movement of the second device is a drawing operation may be determined by whether the second device receives a pre-specified target operation.

Thus, step 1022 may include the following steps 201-203:

step 201, receiving a drawing switch identifier for the motion parameter sent by the second device.

And step 202, determining effective parameters in the motion parameters according to the drawing switch identification.

And step 203, generating a third space track according to the effective parameters.

The drawing switch identifier may identify whether the motion parameter is a valid parameter. Since the motion parameters are obtained in real time, the motion parameters may include valid parameters during rendering, and may also include invalid parameters in a non-rendering state in addition to the valid parameters. The draw switch identification may be generated based on a target operation received by the second device. For example, after the user presses a drawing button on the smart stylus (second device), or the user clicks the drawing button on the smart stylus to turn on the drawing function, the smart stylus sets the drawing switch flag to on; when the user releases the drawing or closes the drawing button, the smart stylus sets the drawing switch flag to off. The drawing switch identifier and the motion parameter can be synchronously sent to the first equipment, so that the effective parameter in the motion parameter can be determined according to the drawing switch identifier, the outline of the 1 st three-dimensional graph is generated according to the effective parameter, and the third space track is obtained.

In an exemplary embodiment, the second spatial trajectory is an outline of the first stereographic. The first solid figure can be a polyhedron, and each surface of the polyhedron is a polygon. After receiving the first input requesting to unlock the target information in step 101, an image of an outline of a second stereoscopic graphic based on the target viewing angle may also be displayed on the display screen of the first device, where the second stereoscopic graphic is a part of the first stereoscopic graphic, such as the first stereoscopic graphic shown in fig. 3 and the second stereoscopic graphic shown in fig. 4. At this time, the acquired first spatial trajectory may be an outline of the stereoscopic graphic drawn by the user. Thus, in step 103, one embodiment of determining that the parameter of the first spatial trajectory matches the second spatial trajectory may be to combine the first spatial trajectory with the contour of the second stereo graphic to obtain a contour of the third stereo graphic, and then determine whether an error between the contour of the third stereo graphic and the contour of the first stereo graphic is within a second preset range. And if the first spatial trajectory is within a second preset range, determining that the parameters of the first spatial trajectory match the second spatial trajectory.

It should be noted that the target viewing angle may be a preset viewing angle. When the first device is a head-mounted device, the target view angle is a view angle of a preset direction (for example, the preset direction may be a direction toward the front in the middle of two lenses of the head-mounted device) in a coordinate system of the head-mounted device at a spatial position where the head-mounted device is located.

In one example, after acquiring the parameters of the first spatial trajectory drawn by the second device paired with the first device through motion in space in step 102, the imaging of the parameters of the first spatial trajectory based on the target viewing angle may also be displayed on the display screen of the head-mounted device, where the display screen of the head-mounted device is a lens of the head-mounted device, and the target viewing angle is a viewing angle at a spatial position where the head-mounted device is located and facing a preset direction in a coordinate system of the head-mounted device.

In an example embodiment, the user may also set the second spatial trajectory before receiving the first input requesting the unlock target information in step 101. Specifically, before the step 101 is executed, the method further comprises the following steps 104-105:

step 104, receiving a second input requesting to set a second spatial trajectory.

And 105, acquiring a second space track drawn by the motion of the second device in the space.

The interaction mode between the first device and the second device when the second spatial trajectory is drawn may be similar to that when the first spatial trajectory is drawn, and details are not repeated here. Optionally, in order to prevent jitter of the spatial trajectory caused by unstable user operation, after obtaining the spatial trajectory drawn by the user operating the second device, smooth correction may be performed to obtain the second spatial trajectory.

According to the information unlocking method provided by the embodiment of the application, a user can draw the first space track in the space through the second device, the first device is matched with the known second space track to serve as the key of the unlocking information, another new unlocking mode is provided, and due to the fact that the track of the second device moving in the space is not easy to observe by others in the onlooker process, the good effect of keeping the unlocking key secret can be achieved, and the safety of information privacy is improved. When the method is applied to a scene of the head-mounted equipment, other people cannot see the imaging of the stereoscopic graph in the glasses, and the safety of the secret key is further improved.

The information unlocking method provided by the embodiment of the present application is exemplarily described below with reference to an optional specific application scenario.

In this application scenario, the first device is a 3D (three-dimensional stereo) smart glasses and the second device is a smart stylus. Firstly, the connection is established through bluetooth or WIFI to intelligence handwriting pen and 3D intelligent glasses, and establishes the connection back, and the data of intelligence handwriting pen and intelligent glasses can pass each other in real time. The intelligent handwriting pen is provided with sensors such as a gravity acceleration sensor, a gyroscope, geomagnetism and the like, and the processor on the intelligent handwriting pen can calculate the motion trail of the handwriting pen through related data provided by the sensors; meanwhile, the 3D graph track drawn by the intelligent handwriting pen can be seen in real time through the intelligent glasses. It should be noted that the trajectory displayed in the lens screen of the 3D smart glasses is an image rendered based on the viewing angle of the 3D smart glasses.

First, the user can set a stereoscopic image (first stereoscopic image) as a password. The following are example flow steps of operations when setting a password:

step 501: and the user enters a password setting menu of the 3D intelligent glasses.

Step 502: the software system of the 3D smart glasses prompts the user to draw a 3D graphic.

Step 503: the user draws the 3D graph for the first time by using the intelligent handwriting pen successfully paired with the 3D intelligent glasses.

Step 504: the 3D smart glasses store 3D graphics.

Step 505: the software system of the 3D smart glasses prompts the user to draw the 3D graphic again.

Step 506: and the software system of the 3D intelligent glasses compares the 3D images of the front and the back, if the images are consistent (the difference is within a preset range), the step 507 is carried out, and if the images are not consistent, the step 505 is returned.

Step 507: and reminding the user of successful password setting.

Then, after the user has set the second spatial trajectory as a password, two exemplary embodiments are provided for unlocking.

One exemplary embodiment, among others, includes the following process steps:

step 601: the user initiates a request to access an already encrypted file system (unlock target information) in the software system of the 3D smart glasses.

Step 602: the software system of the 3D smart glasses prompts the user to enter an unlocking password.

Step 603: the user hand-draws 3D graphics with the smart stylus.

Step 604: the software system of the 3D intelligent glasses compares a 3D graph (an image formed by the outline of the first space track) drawn by the hand of the user with a graph (a first stereo graph) preset by the software system of the 3D intelligent glasses. If so, go to step 605, and if not, go back to step 602.

Step 605: unlock and enter the file system.

In the first embodiment, when unlocking is needed, a 3D graph is drawn through the intelligent stylus pen, unlocking can be performed if the drawn 3D graph is consistent with a preset 3D graph, and unlocking fails if the drawn 3D graph is inconsistent with the preset 3D graph. The preset 3D graph may be a specific 3D graph customized by the smart stylus, the image is preset as an encryption key of the file system, and the specific process of setting the key may be as described in steps 501 to 507.

An exemplary embodiment includes the following process steps:

step 701: the user initiates a request to access an already encrypted file system (unlock target information) in the software system of the 3D smart glasses.

Step 702: the 3D smart glasses project a 3D stereoscopic image (second stereoscopic image) on the screen (lens).

Step 703: the user replenishes the remaining 3D graphics with the smart stylus.

Step 704: and the software system of the 3D intelligent glasses compares the 3D graph (third stereo graph) combined after the user replans with the graph (first stereo graph) preset by the software system of the 3D intelligent glasses. If so, step 705 is entered, and if not, step 703 is returned to.

Step 705: unlock and enter the file system.

In the second embodiment, when a user initiates an unlocking application, a software system of the 3D smart glasses projects a local graphic (a second stereoscopic graphic) of the unlocking key (a first stereoscopic graphic) first, the user supplements the remaining graphics through the smart stylus pen, and if the final completed graphic (a third stereoscopic graphic) is consistent with the preset 3D graphic (the first stereoscopic graphic), the unlocking is possible, and if the final completed graphic (the third stereoscopic graphic) is not consistent with the preset 3D graphic (the first stereoscopic graphic), the unlocking fails.

Compared with unlocking modes such as password setting and unlocking gestures in the related art, the implementation method provided by the example can utilize the advantage that a user wears the 3D intelligent glasses, and enables people around to be incapable of observing the drawn graphs through naked eyes while accurately drawing the 3D graphs.

In one example, the smart stylus may be paired with a plurality of 3D smart glasses, and if a second user wears the 3D smart glasses around the first user, even though the second user may see a stereoscopic graphic drawn by the first user, the stereoscopic graphic drawn by the first user is an image presented by the first user based on a viewing angle of the second user, and the second user still cannot accurately know the 3D graphic drawn by the first user, thereby improving privacy.

The process and related algorithms for drawing 3D graphics in conjunction with the smart stylus and 3D smart glasses are illustrated below with the solid triangular pyramidal map provided in conjunction with fig. 6 as an example of the first solid graphic.

Firstly, pair connection is carried out to intelligence handwriting pen and 3D intelligence glasses through bluetooth or WIFI, and after the connection succeeds, the data between intelligence handwriting pen and the intelligent glasses can carry out mutual biography in real time.

When the user moves from point a to point B shown in fig. 6 with the smart stylus at an initial velocity of 0, a processor on the smart stylus synchronously records a component a of an acceleration sensor (one of the spatial motion sensors) in the direction AB, and the length L of the point AB can be calculated by using a formula L ═ (1/2) × a × t2 when the smart stylus moves from point a to point B. The lengths of the line segments AC and AD can be calculated based on the same principle.

In the process of moving the intelligent stylus from A to B, the processor on the intelligent stylus can obtain the deflection angle beta 1 of the geomagnetism through a geomagnetic sensor (one of the space motion sensors); in the process of moving from A to C, the processor on the intelligent stylus can obtain the deflection angle beta 2 of the geomagnetism through the geomagnetic sensor; the angle β between the line AB and AC can thus be calculated as | β 1- β 2 |.

In the process of moving the intelligent stylus from A to C, the processor on the intelligent stylus can obtain the deflection angle alpha 1 of the gyroscope through the gyroscope sensor (one of the spatial motion sensors); in the process of moving from A to D, the processor on the intelligent stylus can obtain the deflection angle alpha 2 of the gyroscope through the gyroscope sensor; the angle α | α 1- α 2| between the straight lines AC and AD can thus be calculated.

According to the data, all information of the drawn 3D graph can be obtained by a processor on the intelligent handwriting pen, the information is transmitted to the 3D intelligent glasses in real time to be displayed, and the information can be stored in a software system of the 3D intelligent glasses.

The following describes an exemplary detailed description of the procedure when comparing two 3D graphics in the embodiment of the present application. This is also illustrated in the three-dimensional triangular pyramid pattern of fig. 6.

Firstly, a 3D graph (a stereoscopic graph formed by the outline of the first spatial trajectory) drawn by a user and a 3D graph (a first stereoscopic graph) preset by a software system of the 3D smart glasses are put in the same coordinate axis by a software system of the 3D smart glasses, and the coordinates of the point a are overlapped.

After the above operations, the coordinates of the three points B, C, D are compared. Taking the example of the comparison of the coordinates of the B point, if the coordinates of the B point of the preset graph are (Xb, Yb, Zb), and the coordinates of the B point of the graph drawn by the user are (Xb ', Yb', Zb '), the absolute values | Xb-Xb' |, | Yb-Yb '|, and | Zb-Zb' | of the difference values are calculated, and if the above values are respectively less than 5mm, the coordinate values are considered to be the same. Using the same algorithm, the coordinate values of the keypoints such as C, D can be compared.

When the coordinate values are the same, the line lengths of the key profiles are compared. For example, if the line lengths of the AB, AC, and AD of the preset graph are Lab, Lac, and Lad, respectively, the line lengths of the AB, AC, and AD of the graph drawn by the user are Lab ', Lac', and Lad ', respectively, and then absolute values of the differences | Lab-Lab' |, | Lac-Lac '|, and | Lad-Lad' |, are calculated, and if the above values are less than 5mm (preset), respectively, the lengths are considered to be the same.

If the coordinate difference and the length difference can meet the requirements, the graphs are considered to be consistent, and if one or more of the graphs are different, the graphs are considered to be inconsistent.

The embodiment of the application also provides an information unlocking device. It should be noted that in the information unlocking method provided in the embodiment of the present application, the execution main body may be an information unlocking device, or a control module in the information unlocking device, which is used for executing the loaded information unlocking method. In the embodiment of the present application, an information unlocking method executed by an information unlocking device is taken as an example, and the information unlocking method provided in the embodiment of the present application is described.
