[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The electronic device unlocking method, apparatus, device, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0033] The electronic device unlocking method and apparatus provided in this application can be applied to a first electronic device, which can be a terminal or other devices besides a terminal. For example, the first electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc. This application does not specifically limit the application.

[0034] The first electronic device in this application embodiment can be an electronic device with an operating system. The operating system can be Android, iOS, or other possible operating systems; this application embodiment does not specifically limit the specific operating system.

[0035] Figure 1 This is a flowchart illustrating the electronic device unlocking method provided in this application embodiment. The electronic device unlocking method applied to the first electronic device may include:

[0036] Step 101: Receive target information sent by the second electronic device, wherein the second electronic device is an electronic device worn on the user's head, and the target information includes the orientation of the second electronic device and the first distance between the second electronic device and the first electronic device.

[0037] The second electronic device in this application embodiment includes, but is not limited to: headphones, head-mounted display devices (e.g., virtual reality (VR) glasses, augmented reality (AR) glasses), and may also be other electronic devices that can be worn or attached to the head.

[0038] Step 102: Determine the user's line of sight based on the orientation of the second electronic device.

[0039] Step 103: Determine whether there is an intersection between the line of sight and the screen of the first electronic device based on the first distance. If so, proceed to step 104.

[0040] Step 104: If the line of sight intersects with the screen of the first electronic device based on the first distance, unlock the first electronic device.

[0041] The specific implementation methods of the above steps will be described in detail below.

[0042] In this embodiment, the first electronic device receives the orientation direction of the second electronic device and the first distance between the second electronic device and the user's head from a second electronic device worn on the user's head. Based on the orientation direction of the second electronic device, it determines the user's line of sight. Based on the first distance, it determines whether the user's line of sight intersects with the screen of the first electronic device. If the user's line of sight intersects with the screen of the first electronic device, the first electronic device is unlocked. This allows the electronic device to be unlocked based on the user's line of sight, increasing the diversity of unlocking methods.

[0043] It is understandable that when the user's line of sight intersects with the screen of the first electronic device, the user's line of sight falls on the screen of the first electronic device.

[0044] In some possible implementations of this application's embodiments, the second electronic device may include an electronic compass, a gyroscope, and a communication module. The electronic compass determines the horizontal direction based on the strength of the current in the "Hall effect." The gyroscope is a device that uses the angular momentum of a high-speed rotating body to sense the angular motion of its housing relative to inertial space around one or two axes orthogonal to its rotation axis, used to measure the angle between the orientation direction of the second electronic device and the horizontal direction. The second electronic device determines its orientation direction using the data measured by the electronic compass and gyroscope. This application's embodiments do not elaborate on the specific process of determining the orientation direction of the second electronic device using the data measured by the electronic compass and gyroscope; for details, please refer to the descriptions in related technologies. The communication module is used to transmit the orientation direction of the second electronic device to the first electronic device.

[0045] In some possible implementations of this application's embodiments, in step 102, the direction of the user's gaze can be determined based on the relative positional relationship between the user's eyes and the second electronic device.

[0046] In some possible implementations of the embodiments of this application, when determining the direction of the user's gaze based on the relative positional relationship between the user's eyes and the second electronic device, the orientation direction of the second electronic device can be rotated in three dimensions based on the relative positional relationship between the user's eyes and the second electronic device to obtain the direction of the user's gaze.

[0047] For example, if the second electronic device is directly in front of the user's eyes, then the orientation of the second electronic device is the direction of the user's line of sight.

[0048] For another example, if the second electronic device is located 5 centimeters from the center of the user's eyes on the forehead, then the second electronic device is rotated according to the rotation matrix corresponding to the location of the second electronic device at 5 centimeters from the center of the user's eyes on the forehead to obtain a coordinate. This coordinate is the coordinate of the user's eyes, and the direction of the intersection of this coordinate is the direction of the user's gaze. The intersection is the intersection of the orientation direction of the second electronic device and the plane where the screen of the first electronic device is located.

[0049] In some possible implementations of this application's embodiments, step 102 may include: taking the orientation of the second electronic device as the user's line of sight.

[0050] Typically, the orientation of a second electronic device worn on a user's head is roughly the same as the user's line of sight; even if there is a slight deviation, it is negligible. Therefore, the orientation of the second electronic device can be used as the user's line of sight.

[0051] In some possible implementations of this application embodiment, step 103 may include: determining a second distance from the second electronic device to the target point, a third distance from the second electronic device to the first position point, a third distance from the second electronic device to the second position point, a first angle between the oriented direction and the plane where the screen is located, a second angle between the line segment from the second electronic device to the second position point and the plane where the screen is located, and a third angle between the line segment from the second electronic device to the first position point and the plane where the screen is located, where the target point is the intersection of the oriented direction and the plane where the screen of the first electronic device is located, the first position point is the position point on the screen closest to the second electronic device, and the second position point is the position point on the screen farthest from the second electronic device; if the second distance is greater than or equal to the third distance and less than or equal to the fourth distance, and the first angle is greater than or equal to the second angle and less than or equal to the third angle, determining that the line of sight intersects with the screen of the first electronic device.

[0052] For example, such as Figures 2 to 4 As shown. Figure 2 This is a schematic diagram illustrating a first relationship between the line of sight and the screen of the first electronic device, provided in an embodiment of this application. Figure 3 This is a schematic diagram illustrating a second relationship between the line of sight and the screen of the first electronic device, provided in an embodiment of this application. Figure 4 This is a schematic diagram illustrating a third relationship between the line of sight and the screen of the first electronic device, provided in an embodiment of this application. Figure 2 and Figure 3In this case, the user's gaze is not fixed on the screen of the first electronic device; Figure 4 In this context, the user's gaze is fixed on the screen of the first electronic device.

[0053] exist Figures 2 to 4 In the diagram, the line of sight from point O to point P represents the user's line of sight; the second distance is the distance from point O to point P; the third distance is the distance from point O to point C; and the fourth distance is the distance from point O to point A. Point O represents the position of the second electronic device (i.e., the position of the user's eye); O' is the projection of point O onto the plane of the screen of the first electronic device; point P is the intersection of the orientation direction of the second electronic device and the plane of the screen of the first electronic device; and points A, B, C, and D are the four vertices of the screen of the first electronic device.

[0054] The first angle is ∠OPO', the second angle is ∠OCO', and the third angle is ∠OAO'.

[0055] In some possible implementations of this application, the second electronic device may include a pulse signal transmitting module, and the first electronic device may be equipped with a pulse signal receiving module. The pulse signal transmitting module can transmit a pulse signal, and the distance from the second electronic device to the pulse signal receiving module can be calculated using the pulse signal and the target echo (i.e., the signal reflected by the pulse signal receiving module).

[0056] In some possible implementations of the embodiments of this application, the distance from the second electronic device to the pulse signal receiving module is the first distance from the second electronic device to the first electronic device.

[0057] For example, a pulse signal transmitting module transmits a pulse signal with a pulse width of x and a period of T. Assuming the speed of propagation of the pulse signal in the air is c, the distance between the pulse signal transmitting module and the pulse signal receiving module is R, and the delay of the target echo relative to the pulse signal transmitted by the pulse signal transmitting module is t, then R = c * t / 2.

[0058] Since the pulse signal transmitting module is located on the second electronic device and is relatively small, the distance between the second electronic device and the pulse signal receiving module is less affected by the pulse signal transmitting module. Therefore, the distance between the pulse signal transmitting module and the pulse signal receiving module can be used as the distance between the second electronic device and the pulse signal receiving module.

[0059] In some possible implementations of this application, the pulse signal receiving module can be located by the pulse signal transmitting module to obtain the three-dimensional coordinates of the pulse signal receiving module. Based on the positional relationship of the pulse signal receiving module relative to the four corner vertices of the screen of the first electronic device, the three-dimensional coordinates of the four corner vertices of the screen of the first electronic device are determined. Then, the distance from the second electronic device to the intersection of the orientation direction of the second electronic device and the plane where the screen of the first electronic device is located, the distance from the second electronic device to the nearest point on the screen, the distance from the second electronic device to the farthest point on the screen, the angle between the orientation direction of the second electronic device and the plane where the screen is located, the angle between the line segment from the second electronic device to the nearest point on the screen and the plane where the screen is located, and the angle between the line segment from the second electronic device to the farthest point on the screen and the plane where the screen is located are determined.

[0060] For example, taking a pulse signal transmitting module including a synthetic aperture radar as an example, the calculation of the three-dimensional coordinates of the pulse signal receiving module will be explained. Figure 5 As shown, Figure 5 This is a schematic diagram showing the positions of the synthetic aperture radar and the pulse signal transmission module provided in the embodiments of this application.

[0061] Among them, Figure 5 In the diagram, point G to point H represents the direction of movement of the synthetic aperture radar (i.e., the direction of movement of the second electronic device), R1 is the distance from point G to point X of the pulse signal receiving module, R2 is the distance from point H to point X of the pulse signal receiving module, fD1 is the Doppler frequency of the synthetic aperture radar imaging at point G, and fD2 is the Doppler frequency of the synthetic aperture radar imaging at point H.

[0062] In the Earth-fixed coordinate system, according to the Doppler equation and slant range equation of radar, the following relationship exists as shown in formula (1):

[0063]

[0064] In formula (1), PS1 is the position vector of the synthetic aperture radar at point G, PS2 is the position vector of the synthetic aperture radar at point H, PT is the position vector of the pulse signal receiving module at point X, VS1 is the velocity vector of the synthetic aperture radar at point G, VS2 is the velocity vector of the synthetic aperture radar at point H, and λ is the wavelength of the electromagnetic wave (i.e., pulse signal) emitted by the synthetic aperture radar.

[0065] Among them, R1, R2, fD1, fD2, PS1, PS2, VS1 and VS2 can all be obtained by synthetic aperture radar measurement, and λ is a known quantity.

[0066] In the Earth-fixed coordinate system, the positional relationship between the first electronic device and the second electronic device is as follows: Figure 6 As shown, Figure 6 This is a schematic diagram illustrating the positional relationship between the first electronic device and the second electronic device provided in an embodiment of this application. Figure 6 In the diagram, the X-axis, Y-axis, and Z-axis are the coordinate axes of the Earth-fixed coordinate system, O is the origin of the coordinate axes, A, B, C, and D are the four vertices of the screen of the second electronic device, E is the position of the second electronic device, and the direction from E to F is the orientation of the second electronic device, i.e. the direction of the user's eye gaze.

[0067] In some possible implementations of the embodiments of this application, three equations (i.e., equalities) can be selected from the above formula (1) to solve for the three-dimensional coordinates of point X of the pulse signal receiving module; or the above formula (1) can be solved by the least squares method to obtain the three-dimensional coordinates of point X of the pulse signal receiving module.

[0068] After obtaining the three-dimensional coordinates of point X of the pulse signal receiving module, further, based on the positional relationship of point X of the pulse signal receiving module relative to the four corners of the screen of the first electronic device, the three-dimensional coordinates of the four corners of the screen of the first electronic device can be determined. Then, the distance from the second electronic device to the intersection of the orientation direction of the second electronic device and the plane where the screen of the first electronic device is located, the distance from the second electronic device to the nearest point on the screen, the distance from the second electronic device to the farthest point on the screen, the angle between the orientation direction of the second electronic device and the plane where the screen is located, the angle between the line segment from the second electronic device to the nearest point on the screen and the plane where the screen is located, and the angle between the line segment from the second electronic device to the farthest point on the screen and the plane where the screen is located.

[0069] For example, suppose that point X of the pulse signal receiving module is related to the above... Figures 2 to 4 If point A in the diagram coincides with point X, then the three-dimensional coordinates of point X on the pulse signal receiving module are... Figures 2 to 4 The coordinates of point A in the image are given. Then, based on the coordinates of point A, the coordinates of point O, and the positional relationships of each vertex (including the screen side length and screen tilt angle), the coordinates of points B, C, D, and O' can be calculated.

[0070] The length of OA (i.e., the distance from the second electronic device to the farthest point on the screen) can be calculated based on the coordinates of point O and point A. The degree of ∠OAO' (i.e., the angle between the line segment from the second electronic device to the farthest point on the screen and the plane in which the screen is located) can be calculated based on the coordinates of point O, point A, and point O'.

[0071] The length of OC (i.e., the distance from the second electronic device to the nearest point on the screen) can be calculated based on the coordinates of point O and point C. The degree measure of ∠OCO' (i.e., the angle between the line segment from the second electronic device to the nearest point on the screen and the plane in which the screen is located) can be calculated based on the coordinates of point O, point C, and point O'.

[0072] Once the distances from the second electronic device to the intersection of its orientation direction and the plane where the screen of the first electronic device is located, the distances from the second electronic device to the nearest point on the screen, the distances from the second electronic device to the farthest point on the screen, the angle between the orientation direction of the second electronic device and the plane where the screen is located, the angle between the line segment from the second electronic device to the nearest point on the screen and the plane where the screen is located, and the angle between the line segment from the second electronic device to the farthest point on the screen and the plane where the screen is located, can be determined whether there is an intersection between the user's line of sight and the screen of the first electronic device, i.e., whether the user's line of sight falls on the screen of the first electronic device, can be determined. When the user's line of sight falls on the screen of the first electronic device, the first electronic device is unlocked; when the user's line of sight does not fall on the screen of the first electronic device, the first electronic device is not unlocked and remains in a locked state.

[0073] For example, for the above Figures 2 to 4 When OP is greater than OC and less than OA, and ∠OPO' is greater than ∠OAO' and less than ∠OCO', point P is located within ABCD, meaning the user's line of sight falls on the screen of the first electronic device.

[0074] When OP is less than OC, or OP is greater than OA, or ∠OPO' is less than ∠OAO', or ∠OPO' is greater than ∠OCO', point P is located outside ABCD, meaning the user's line of sight is not on the screen of the first electronic device.

[0075] In some possible implementations of the embodiments of this application, in order to improve unlocking efficiency and reduce computational load, the pulse signal receiving module can be set at any one of the four corners of the screen of the first electronic device.

[0076] Based on the above, the second electronic device in this application embodiment includes a synthetic aperture radar, and the second range, third range, fourth range, first angle, second angle and third angle are calculated based on the radar's Doppler equation and slant range equation.

[0077] In some possible implementations of the embodiments of this application, before step 104, the electronic device unlocking method provided in the embodiments of this application may further include: obtaining the identification information of the second electronic device; verifying the identification information; accordingly, step 104 may include: unlocking the first electronic device if the identification information passes the verification.

[0078] In some possible implementations of this application, the first electronic device may pre-store identification information of other electronic devices owned by the user. When the user's gaze falls on the screen of the first electronic device, the identification information of the second electronic device is obtained. The system then checks if there is any identification information identical to that of the second electronic device in the pre-stored identification information. If such information exists, it indicates that the user unlocking the first electronic device through gaze is the owner of the first electronic device, and the first electronic device is unlocked. If such information does not exist, it indicates that the user unlocking the first electronic device through gaze is not the owner of the first electronic device, but another user, and the first electronic device is not unlocked.

[0079] In the embodiments of this application, it is possible to prevent electronic devices from being unlocked by non-electronic device owners, prevent user privacy from being leaked, and improve data security.

[0080] The electronic device unlocking method provided in this application can be executed by an electronic device unlocking device. This application uses an electronic device unlocking device executing the electronic device unlocking method as an example to illustrate the electronic device unlocking device provided in this application.

[0081] Figure 7 This is a schematic diagram of the structure of the electronic device unlocking device provided in this application embodiment. The electronic device unlocking device 700 may include:

[0082] The receiving module 701 is used to receive target information sent by the second electronic device, wherein the second electronic device is an electronic device worn on the user's head, and the target information includes the orientation of the second electronic device and the first distance between the second electronic device and the first electronic device.

[0083] The determining module 702 is used to determine the direction of the user's eye gaze based on the orientation of the second electronic device;

[0084] The judgment module 703 is used to determine whether there is an intersection between the line of sight and the screen of the first electronic device based on the first distance. If there is an intersection between the line of sight and the screen of the first electronic device, the unlocking module 704 is triggered.

[0085] Unlock module 704 is used to unlock the first electronic device.

[0086] In this embodiment, the first electronic device receives the orientation direction of the second electronic device and the first distance between the second electronic device and the user's head from a second electronic device worn on the user's head. Based on the orientation direction of the second electronic device, it determines the user's line of sight. Based on the first distance, it determines whether the user's line of sight intersects with the screen of the first electronic device. If the user's line of sight intersects with the screen of the first electronic device, the first electronic device is unlocked. This allows the electronic device to be unlocked based on the user's line of sight, increasing the diversity of unlocking methods.

[0087] In some possible implementations of the embodiments of this application, the determining module 702 is specifically used for:

[0088] The orientation of the second electronic device is taken as the direction of the user's eye gaze.

[0089] In some possible implementations of the embodiments of this application, the determination module 703 may specifically be used for:

[0090] The following distances are determined based on the first distance: the second distance from the second electronic device to the target point, the third distance from the second electronic device to the first position point, the third distance from the second electronic device to the second position point, the first angle between the oriented direction and the plane where the screen is located, the second angle between the line segment from the second electronic device to the second position point and the plane where the screen is located, and the third angle between the line segment from the second electronic device to the first position point and the plane where the screen is located. The target point is the intersection of the oriented direction and the plane where the screen of the first electronic device is located. The first position point is the position point on the screen that is closest to the second electronic device, and the second position point is the position point on the screen that is farthest from the second electronic device.

[0091] When the second distance is greater than or equal to the third distance and less than or equal to the fourth distance, and the first angle is greater than or equal to the second angle and less than or equal to the third angle, it is determined that the line of sight intersects with the screen of the first electronic device.

[0092] In some possible implementations of the embodiments of this application, the second electronic device includes a synthetic aperture radar, and the second range, third range, fourth range, first angle, second angle and third angle are calculated based on the radar's Doppler equation and slant range equation.

To avoid repetition, they will not be described again here.

[0099] The electronic device 800 provided in this application embodiment may further include a pulse signal receiving module for determining the distance between the electronic device 800 and the second electronic device.
