Description

Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to smart glasses, a control method for smart glasses, a storage medium, and a system. Background Art

[0002] As a wearable intelligent terminal device, smart glasses can meet the user's needs for wearing glasses while providing users with services in learning, work, and entertainment, providing convenience for users.

[0003] Users can control smart glasses through physical button control or voice control. When using physical button control, smart glasses generally have physical function buttons on the temples. During use, if the user needs to press a button to take a photo or adjust the volume of the audio, they need to press the corresponding physical button on the temple with their fingers. However, it is inconvenient for the user to press these buttons with their fingers when wearing glasses, or it is easy to press them by mistake, which brings inconvenience to the user. When using voice control, users can control smart glasses by speaking, but this requires smart glasses to have accurate voice recognition technology and be equipped with relatively expensive supporting devices. In addition, the voice recognition solution is often inconvenient for users with language barriers and when the user is in an environment where it is inconvenient to speak, such as when the user is in a library, classroom or conference room.

[0004] In summary, the current control method of smart glasses has the problem of inconvenient control, which affects the user experience. Summary of the Invention

[0005] In order to solve the above problems, the present application provides a pair of smart glasses, a control method for smart glasses, a storage medium and a system, which enable users to control the smart glasses more conveniently and improve the user experience.

[0006] In a first aspect, the present application provides a pair of smart glasses, which include a first group of receiving coils, a second group of receiving coils, a first conversion circuit, a second conversion circuit, and a processor; the first conversion circuit is used to convert the induced current generated by the first group of receiving coils into direct current, and use the direct current to generate a first voltage value; the second conversion circuit is used to convert the induced current generated by the second group of receiving coils into direct current, and use the direct current to generate a second voltage value; the processor is used to control the smart glasses to implement a first function in a first group of functions according to the first voltage value when the first voltage value is greater than or equal to a voltage threshold, otherwise, not control the smart glasses to implement the first function according to the first voltage value; when the second voltage value is greater than or equal to the voltage threshold, control the smart glasses to implement a second function in a second group of functions according to the second voltage value, otherwise, not control the smart glasses to implement the second function according to the second voltage value.

[0007] The solution of this application is equipped with a receiving coil and a conversion circuit on smart glasses. When the receiving coil generates an alternating current using an alternating magnetic field, the conversion circuit converts the alternating current into direct current, generates a voltage value using the direct current, and outputs it to a processor, so that the processor can implement the corresponding control function based on the voltage value. The first function implemented when the first voltage value is greater than or equal to the voltage threshold, and the second function implemented when the second voltage value is greater than or equal to the voltage threshold, respectively, belong to two groups of functions. The first group of functions and the second group of functions can be completely different or partially the same. The alternating magnetic field can be generated by a wearable electronic device such as a smartwatch. This solution does not require the user to click buttons on the smart glasses, avoiding accidental touches, nor does it require the user to control the smart glasses through voice control. Therefore, it does not require the use of voice recognition technology or the installation of relatively expensive supporting components. Even when the user is in an environment where speaking is not convenient, the smart glasses can still be controlled normally. Therefore, this solution allows users to control smart glasses more conveniently, improving the user experience.

[0008] In one possible implementation, the first set of receiving coils and the second set of receiving coils are symmetrically distributed on the smart glasses. In this case, when a user controls the smart glasses using a smart watch, they can control the smart glasses from both sides.

[0009] In a possible implementation, the smart glasses further include a left frame and a right frame, the first set of receiving coils is disposed on the left frame, and the second set of receiving coils is disposed on the right frame. The receiving coils are disposed on both frames.

[0010] At this time, the magnetic induction area of the receiving coil is large, and a relatively large induced current can be generated, which is convenient for controlling from both sides.

[0011] In a possible implementation, the smart glasses further include a first temple and a second temple; the first group of receiving coils is arranged on the first temple; and the second group of receiving coils is arranged on the second temple.

[0012] At this time, when the user uses the smart watch to control the smart glasses, the control is performed from both sides of the smart glasses, so the user's vision will not be disturbed during the control process, thereby improving the user experience.

[0013] In one possible implementation, the first set of receiving coils includes a first receiving coil, and the second set of receiving coils includes a second receiving coil. The magnetic induction areas of the first receiving coil and the second receiving coil should be substantially the same so that the user's movements in different directions remain the same.

[0014] In one possible implementation, the first receiving coil group includes multiple receiving coils, and the second receiving coil group includes multiple receiving coils. The sum of the magnetic induction areas of the coils in the first receiving coil group should be substantially the same as the sum of the magnetic induction areas of the coils in the second receiving coil group, so that the user's movement amplitudes when controlling the smart glasses in different directions are consistent.

[0015] In one possible implementation, the first conversion circuit includes: a first detection circuit, a first switch, and a first resistor. The input port of the first detection circuit is connected to the first set of receiving coils, and the output port of the first detection circuit is connected in series with the first switch and the first resistor. The first detection circuit is configured to convert the alternating current output by the first set of receiving coils into direct current, and the voltage across the first resistor is a first voltage value. The second conversion circuit includes: a second detection circuit, a second switch, and a second resistor. The input port of the second detection circuit is connected to the second set of receiving coils, and the output port of the second detection circuit is connected in series with the second switch and the second resistor. The second detection circuit is configured to convert the alternating current output by the second set of receiving coils into direct current, and the voltage across the second resistor is a second voltage value.

[0016] In one possible implementation, the processor is specifically configured to, when the first voltage value is greater than or equal to the voltage threshold, determine a first parameter value combination based on the duration during which the first voltage value is greater than or equal to the voltage threshold, and the duration during which the first voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again, and match a first function corresponding to the first parameter value combination from a first group of functions; and when the second voltage value is greater than or equal to the voltage threshold, determine a second parameter value combination based on the duration during which the second voltage value is greater than or equal to the voltage threshold and the duration during which the second voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again, and match a second function corresponding to the second parameter value combination from a second group of functions.

[0017] In this implementation, because the voltage output by the conversion circuit is related to the distance between the smartwatch and the receiving coil, the processor can effectively determine which side of the smart glasses the smartwatch is closer to. This eliminates the need for user settings on either the smartwatch or the smartwatch, simplifying user operations. It also eliminates the need for the smartwatch to emit electromagnetic waves carrying relevant information, simplifying the smartwatch's circuitry. The duration of the first voltage value, after being greater than or equal to the voltage threshold, then again falling below the threshold, indicates whether the current combination of actions being controlled by the smartwatch has concluded.

[0018] In one possible implementation, the first parameter value combination and the second parameter value combination include the parameter value of the first parameter and the parameter value of the second parameter. When the duration of the first voltage value being greater than or equal to the voltage threshold is in the first time period, the processor adds 1 to the parameter value of the second parameter; when the duration of the first voltage value being greater than or equal to the voltage threshold is in the second time period, the processor adds 1 to the parameter value of the first parameter; when the first voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than a third time period, the processor uses the current parameter value of the first parameter and the current parameter value of the second parameter as the first parameter value combination; after determining the first function using the first parameter value combination, the processor resets the parameter value of the first parameter and the parameter value of the second parameter; and in the first time period, the processor resets the parameter value of the first parameter and the parameter value of the second parameter. Greater than a second time period; when the duration that the second voltage value is greater than or equal to the voltage threshold is in the first time period, the parameter value of the second parameter is accumulated by 1; when the duration that the second voltage value is greater than or equal to the voltage threshold is in the second time period, the parameter value of the first parameter is accumulated by 1; when the second voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than a third time period, the current parameter value of the first parameter and the current parameter value of the second parameter are combined as the second parameter value; after determining the second function using the second parameter value combination, the parameter value of the first parameter and the parameter value of the second parameter are reset.

[0019] In this way, the processor of the smart glasses can determine the parameter value combination according to the change of the voltage value, and determine the function corresponding to the action combination of the current smart watch according to the parameter value combination. Different action combinations of the smart watch can correspond to different parameter value combinations.

[0020] In one possible implementation, the smart glasses further include a first temple and a second temple; the first temple includes a first group of buttons, and the second temple includes a second group of buttons; the first group of functions includes all or part of the functions of the first group of buttons, and the second group of functions includes all or part of the functions of the second group of buttons.

[0021] In this implementation, the smart watch controls the functions implemented by the smart glasses without corresponding physical buttons, thereby expanding the application scenarios.

[0022] In one possible implementation, the first group of functions and the second group of functions include one or more of the following: taking photos, recording videos, power control, reducing volume, increasing volume, playing, pausing, recording, switching to the next song, returning to the previous song, and translating.

[0023] In a second aspect, the present application also provides a control system for smart glasses, comprising smart glasses and a smart watch. The smart watch comprises a power conversion circuit and a first set of transmitting coils; the power conversion circuit is configured to generate alternating current from direct current and output the alternating current to the first set of transmitting coils; the first set of transmitting coils is configured to generate an alternating magnetic field from the alternating current, so that when the smart watch is brought into proximity with the smart glasses, the first set of receiving coils and / or the second set of receiving coils of the smart glasses generate an induced current; and the smart glasses control their operation via the induced current.

[0024] With this system, users don't need to click buttons on the smart glasses, preventing accidental touches. They also don't need to control the smart glasses through voice control, eliminating the need for voice recognition technology or expensive accessories. Even when speech isn't convenient, users can still control their smart glasses. This solution allows users to more conveniently control their smart glasses, enhancing their user experience.

[0025] In a possible implementation, the power conversion circuit is a self-excited oscillation circuit, which has a simple circuit structure, low hardware cost, and occupies a small layout space.

[0026] In one possible implementation, the first set of transmitting coils includes a first transmitting coil, which is disposed on the watch face of the smartwatch. Placing the first transmitting coil on the watch face allows the user to always clearly identify the position of the watch face, which corresponds to the position of the first transmitting coil. This facilitates adjusting the relative position of the transmitting coil and the receiving coil during control.

[0027] In one possible implementation, the first set of transmitting coils includes multiple transmitting coils, which are mounted on the smartwatch strap. Once the transmitting coils are mounted on the strap, the strap can be replaced if any of the transmitting coils become damaged. Furthermore, having multiple transmitting coils on the strap increases the combined magnetic induction area of each transmitting coil, thereby improving the precision of controlling the smart glasses.

[0028] In one possible implementation, the smart watch further includes a second processor configured to control the power conversion circuit to start operating in response to a user confirmation operation, wherein the confirmation operation is configured to confirm activation of a function of the smart watch controlling the smart glasses.

[0029] Users can choose to turn on or off the control function of smart glasses on the smart watch. That is, this control function is not a normally on function. When the user is not wearing smart glasses, the function can be turned off on the smart watch, thereby saving power and extending the battery life of the smart watch.

[0030] In a third aspect, the present application also provides a method for controlling smart glasses, which is applied to the control system of the smart glasses provided in the second aspect and any one of the implementation methods of the second aspect above, and can be implemented by the user side. The method includes: turning on control of the smart glasses on the smart watch; determining the sensing position and action combination corresponding to the first smart glasses function from the correspondence between the action combination, the sensing position, and the smart glasses function, the sensing position representing the position of the first group of receiving coils or the second group of receiving coils, the action combination indicating the number of times the smart watch approaches the sensing position, and the duration of each approach to the sensing position; according to the sensing position corresponding to the first smart glasses function, controlling the smart watch to complete the action combination corresponding to the first smart glasses function, so that the smart glasses realize the first smart glasses function.

[0031] When users control smart glasses using the above method, they don't need to click buttons on the smart glasses, avoiding accidental touches. They also don't need to rely on voice control to control the smart glasses. Therefore, smart glasses can be controlled without voice recognition technology or expensive accessories. Even in environments where speaking is inconvenient, users can still control their smart glasses normally. This solution allows users to control smart glasses more conveniently, improving the user experience.

[0032] In a fourth aspect, the present application also provides a control method for smart glasses, which is applied to the control system of the smart glasses provided in the above second aspect and any one of the implementation methods of the second aspect, the method comprising: the smart watch generates an alternating magnetic field through a first set of transmitting coils; the smart watch approaches the smart glasses once or multiple times, so that the first set of receiving coils and / or the second set of receiving coils of the smart glasses generate an induced current; and the smart glasses are controlled by the induced current.

[0033] This method uses a smartwatch to generate and transmit an alternating magnetic field. A receiving coil is installed on the smart glasses. When the receiving coil uses the alternating magnetic field to generate an alternating current, the generated induced current is used to implement the corresponding control function. Users do not need to click buttons on the smart glasses, avoiding accidental touches. They also do not need to control the smart glasses through voice control, eliminating the need for voice recognition technology or expensive supporting components. Even when the user is in an environment where speaking is not convenient, the smart glasses can still be controlled normally. Therefore, this solution allows users to more conveniently control the smart glasses, improving the user experience.

[0034] In one possible implementation, controlling the smart glasses using induced current includes: converting the induced current generated by the first set of receiving coils into direct current to generate a first voltage value; and converting the induced current generated by the second set of receiving coils into direct current to generate a second voltage value. When the first voltage value is greater than or equal to a voltage threshold, the smart glasses are controlled to perform a first function in a first set of functions according to the first voltage value; otherwise, the smart glasses are not controlled to perform the first function. When the second voltage value is greater than or equal to the voltage threshold, the smart glasses are controlled to perform a second function in a second set of functions according to the second voltage value; otherwise, the smart glasses are not controlled to perform the second function.

[0035] In one possible implementation, the smart glasses are controlled to implement a first function in a first group of functions according to a first voltage value, including: when the first voltage value is greater than or equal to a voltage threshold, the smart glasses determine a first parameter value combination according to a duration during which the first voltage value is greater than or equal to the voltage threshold, and a duration during which the first voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again; a first function corresponding to the first parameter value combination is matched from the first group of functions, and the first function is implemented; the smart glasses are controlled to implement a second function in a second group of functions according to a second voltage value, including: when the second voltage value is greater than or equal to the voltage threshold, the smart glasses determine a second parameter value combination according to a duration during which the second voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again, when the second voltage value is greater than or equal to the voltage threshold; a second function corresponding to the second parameter value combination is matched from the second group of functions, and the second function is implemented.

[0036] In one possible implementation, the first parameter value combination and the second parameter value combination include a parameter value of the first parameter and a parameter value of the second parameter. The first parameter value combination is determined based on a duration during which the first voltage value is greater than or equal to a voltage threshold, and a duration during which the first voltage value is less than the voltage threshold again after being greater than or equal to the voltage threshold, including: when the duration during which the first voltage value is greater than or equal to the voltage threshold is within a first time period, the smart glasses accumulate the parameter value of the second parameter by 1; when the duration during which the first voltage value is greater than or equal to the voltage threshold is within a second time period, the smart glasses accumulate the parameter value of the first parameter by 1; when the duration during which the first voltage value is greater than or equal to the voltage threshold is within a third time period, the smart glasses accumulate the parameter value of the first parameter and the current parameter value of the second parameter by 1. The parameter values of the two parameters are used as a first parameter value combination, and the first time period is greater than the second time period; the second parameter value combination is determined based on the duration that the second voltage value is greater than or equal to the voltage threshold, and the duration that the second voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again, specifically including: when the duration that the second voltage value is greater than or equal to the voltage threshold is in the first time period, the smart glasses accumulate the parameter value of the second parameter by 1; when the duration that the second voltage value is greater than or equal to the voltage threshold is in the second time period, the smart glasses accumulate the parameter value of the first parameter by 1; when the duration that the second voltage value is greater than or equal to the voltage threshold is in the second time period, the smart glasses take the current parameter value of the first parameter and the current parameter value of the second parameter as the second parameter value combination when the duration that the second voltage value is less than the voltage threshold again after being greater than or equal to the voltage threshold is greater than the third time period.

[0037] In one possible implementation, after matching a first function corresponding to a first parameter value combination from a first group of functions, the method further includes: resetting the parameter value of the first parameter and the parameter value of the second parameter; after matching a second function corresponding to a second parameter value combination from a second group of functions, the method further includes: resetting the parameter value of the first parameter and the parameter value of the second parameter.

[0038] In a fifth aspect, the present application also provides a computer-readable storage medium, on which a computer program or instruction is stored. When the computer program or instruction is run, the control method of the smart glasses described in the fourth aspect and any one of the implementation methods of the fourth aspect is executed.

[0060] In order to enable people skilled in the art to more clearly understand the solution of the present application, the application scenario of the technical solution of the present application is first described below.

[0061] See also Figure 1 , this figure is a schematic diagram of the scene provided by this application Figure 1 .

[0062] With the widespread application of wearable smart devices, users can wear a smart watch 10 and smart glasses 20 at the same time.

[0063] The user can play music, take photos and videos, etc. through the smart glasses 20. Preferably, the smart glasses 20 can also provide the user with more functions and services, such as simultaneous interpretation, recording, navigation, etc.

[0064] The user can use the smart watch 10 to obtain the current time, record the number of steps, measure the heart rate, etc.

[0065] In the existing solution, there is no interaction between the smart glasses 20 and the smart watch.

[0066] The solution provided in the embodiment of the present application is intended to enable the user to use the smart watch to control the smart glasses 20 when the user wears the smart watch 10 and the smart glasses 20 at the same time, thereby avoiding the user from controlling the smart glasses through physical buttons or voice control, thereby improving the convenience of the user in controlling the smart glasses.

[0067] The implementation of the technical solution of this application is described in detail below with reference to the accompanying drawings.

[0070] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0071] See also Figure 2 and Figure 3 .in, Figure 2 A schematic diagram of smart glasses provided in an embodiment of the present application; Figure 3 A schematic diagram of a smart watch provided in an embodiment of the present application.

[0072] Figure 2 The smart glasses 20 shown include a middle frame 24, a first temple 231, and a second temple 232. The middle frame includes a left frame 241, a connecting portion 243, and a right frame 242. The connecting portion 243 connects the left and right frames 241 and 242. The left frame 241 connects to the first temple 231 and secures the left lens 251. The right frame 242 connects to the second temple 232 and secures the right lens 252.

[0073] The smart glasses 20 may include one or more buttons. Figure 2 The types and distribution of the buttons are merely examples and do not constitute a limitation on the technical solution of the present application. The following description takes the smart glasses 20 including multiple buttons as an example.

[0074] A first group of buttons among the plurality of buttons is located on the first glasses leg 231 , and a second group of buttons is located on the second glasses leg 232 . Figure 2 The first group of buttons in the mobile phone includes a play / pause button 202, a volume reduction button 203, and a volume increase button 204. The second group of buttons includes a power button 205, a camera button 206, and a video button 207.

[0075] When a user wears the smart glasses 20, he or she can turn on the glasses by long pressing the power button 205; turn on or off the photo taking function by pressing the camera button 206; turn on or off the video recording function by pressing the video recording button 207; press the play / pause button 202 to play or pause the currently watched video, music, or other applications; press the volume down button 203 to lower the current playback volume, or implement related control functions for other applications; press the volume up button 204 to increase the current playback volume, or implement related control functions for other applications.

[0076] The smart glasses 20 in the embodiment of the present application further include: a processor, multiple receiving coils and at least two conversion circuits.

[0077] The multiple receiving coils are used to generate induced current when placed in a changing magnetic field. The induced current is an alternating current.

[0078] The conversion circuit is used to rectify the alternating current generated by the receiving coil into direct current, and then convert the direct current into a voltage value after passing it through a resistor and output it to the processor.

[0079] The processor controls the smart glasses according to the voltage value output by the conversion circuit.

[0080] The multiple receiving coils are divided into a first group of receiving coils and a second group of receiving coils, and each group of receiving coils may include one or more receiving coils. The number of receiving coils included in each group of receiving coils may be the same or different. Preferably, each group of receiving coils includes the same number of coils. The embodiments of the present application do not specifically limit the number of turns of the coils included in each receiving coil.

[0081] In a possible implementation, the first group of receiving coils and the second group of receiving coils are symmetrically distributed on the smart glasses, on both sides of the connecting portion 243 .

[0082] It is understandable that for some smart glasses with special designs, the middle frame of the glasses may not include the connecting portion 243, but the right frame 242 and the right frame 242 are replaced with a larger frame, and the left lens 251 and the right lens 252 are replaced with a larger lens. At this time, part of the first group of receiving coils and the second group of receiving coils can be located in the frame and the other part can be located inside the lens or on the surface of the lens to form a ring structure.

[0083] The at least two conversion circuits are divided into a first group of conversion circuits and a second group of conversion circuits, each group of conversion circuits including one or more conversion circuits. The number of conversion circuits included in each group of conversion circuits can be the same or different. Preferably, each group of receiving coils includes the same number of conversion circuits.

[0084] The first set of conversion circuits is used to connect to the first set of receiving coils and rectify the alternating current output by the first set of receiving coils into direct current.

[0085] The second set of conversion circuits is used to connect to the second set of receiving coils and rectify the alternating current output by the second set of receiving coils into direct current.

[0086] In a possible implementation, the first group of receiving coils and the second group of receiving coils are distributed substantially symmetrically with respect to the connecting portion 243 .

[0087] For ease of explanation, the following example illustrates that each receiving coil group includes one receiving coil and each conversion circuit group includes one conversion circuit. The first receiving coil outputs an alternating current to the first conversion circuit, and the second receiving coil outputs an alternating current to the second conversion circuit.

[0088] Continue to see Figure 2The first receiving coil 21 can be arranged in the left frame 241 or along the edge of the left frame 241 and present a ring shape. The second receiving coil 22 can be arranged in the right frame 242 or along the edge of the right frame 242 and present a ring shape.

[0089] The first conversion circuit (not shown in the figure) can be set in the first glasses leg 231, and the second conversion circuit (not shown in the figure) can be set in the second glasses leg 232.

[0090] Figure 3 The smartwatch 10 shown includes a dial 11, a strap 12, and at least one transmitting coil. The smartwatch 10 provides corresponding functions to the user by installing multiple smart applications.

[0091] The dial 11 is used to carry the components of the smart watch 10, and the strap 12 can fix the dial 11 in the user's wearing position.

[0092] At least one transmitting coil is used to generate an alternating magnetic field using an alternating current, thereby causing the receiving coil on the smart glasses to generate a corresponding induced current.

[0093] The embodiment of the present application does not specifically limit the number of turns of each transmitting coil.

[0094] Figure 3 3 illustrates an implementation in which the smartwatch 10 includes only one transmitting coil, namely the first transmitting coil 13, and the first transmitting coil 13 is located on the dial 301. In this case, the first transmitting coil 13 surrounds the dial and is positioned as close to the outer edge of the dial as possible to increase the magnetic flux.

[0095] In order to enable those skilled in the art to more clearly understand the principle of the technical solution of the present application, the principle of electromagnetic induction is first introduced below.

[0096] See also Figure 4 , which is a schematic diagram of the principle of electromagnetic induction provided in an embodiment of the present application.

[0097] Electromagnetic induction refers to the phenomenon in which changes in the magnetic field cause changes in the electric field, thereby generating an electric current. When current I1 flows through transmitting coil L1, it generates an induced magnetic field. When I1 is in a counterclockwise direction, the induced magnetic field within L1 extends from bottom to top.

[0098] The receiving coil L2 is within the range of the induced magnetic field of the transmitting coil L1. The direction of the magnetic field induced in the receiving coil L2 is opposite to that of the magnetic field generated by the transmitting coil L1, that is, the direction of the magnetic field generated in the receiving coil L2 is from top to bottom. Therefore, the direction of the current I2 induced in the receiving coil L2 is clockwise.

[0099] In the solution provided herein, the smartwatch 10 controls the smart glasses 20 based on the aforementioned electromagnetic induction principle. When a user wears the smartwatch 10, they can activate the control function for the smart glasses 20 on the smartwatch. The smartwatch 10 generates an alternating magnetic field, and by varying the relative distance between the smartwatch 10 and the smart glasses 20, the magnitude of the induced current generated by the receiving coil in the smart glasses 20 is altered. When the smartwatch 10 is not near the smart glasses 20, the receiving coil in the smart glasses 20 does not generate an induced current, and the conversion circuit in the smart glasses 20 does not output a voltage. When the smartwatch 10 is near the smart glasses 20, the receiving coil in the smart glasses 20 generates an induced current, and the conversion circuit in the smart glasses 20 outputs a voltage, which is then supplied to the processor in the smart glasses 20, thereby controlling the smart glasses 20.

[0100] The following first introduces the implementation of the smart watch 10 and the smart glasses 20.

[0101] See also Figure 5 , which is a schematic diagram of the structure of the smart watch provided in an embodiment of the present application.

[0102] The smart watch may include: a processor 101 , a memory 102 , a communication module 103 , a display module 104 , a power conversion 105 , and a first transmitting coil 13 .

[0103] It is understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on smart watches. In other embodiments of the present application, the smart watch may include more or fewer components than shown, or combine or separate certain components, or arrange the components differently. The components shown in the figure can be implemented in hardware, software, or a combination of software and hardware. For example, it may also include energy storage elements such as batteries, and the number of transmitting coils may be multiple.

[0104] The processor 101 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors.

[0105] The controller can generate an operation control signal based on the instruction opcode and timing signal to control instruction fetching and execution. For example, the controller can control the power conversion circuit 105 to generate alternating current (AC) from the DC power supply and output the AC to the first transmitting coil 13, thereby generating an alternating magnetic field.

[0106] The memory 102 may be used to store computer-executable program codes, where the executable program codes include instructions.

[0107] The communication module 103 is used to implement the wireless communication function and / or mobile communication function of the smart watch. The wireless communication function may include Wi-Fi network, Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication technology (NFC), infrared technology (IR), etc. The mobile communication function can provide solutions for wireless communication such as 2G / 3G / 4G / 5G.

[0108] The display module 104 is used to display images, information, etc., and includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Mini-LED, a Micro-LED, a Micro-OLED, a quantum dot light-emitting diode (QLED), etc.

[0109] The power conversion circuit 105 is used to convert the direct current output by the DC power supply into alternating current and output it to the first transmitting coil 13. The power conversion circuit 105 can be an inverter circuit, i.e., a direct current (DC)-alternating current (AC) circuit, or a self-excited oscillation circuit, which is not specifically limited in this embodiment of the present application.

[0110] See also Figure 6 , which is a schematic diagram of the structure of the smart glasses provided in an embodiment of the present application.

[0111] The smart glasses may include: a processor 211 , a memory 212 , a communication module 213 , a display module 214 , a first conversion circuit 251 , a first receiving coil 21 , a second conversion circuit 252 , and a second receiving coil 22 .

[0112] It is understandable that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the smart watch. In other embodiments of the present application, the smart watch may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The illustrated components can be implemented in hardware, software, or a combination of software and hardware. For example, it also includes energy storage elements such as batteries, the first receiving coil can be replaced by a first group of receiving coils including multiple receiving coils, and the second receiving coil can be replaced by a second group of receiving coils including multiple receiving coils.

[0113] The description of the processor 211, memory 212, and communication module 213 can be found in the smartwatch and will not be repeated here. The display module 214 includes optical components and is used to display images on the lenses using these components. Each conversion circuit in the smart glasses includes a detection circuit, which can also be considered a rectifier circuit. This circuit is used to rectify the AC power generated by the corresponding receiving coil into DC power, and the voltage generated by the DC power passing through the resistor is used as the output voltage.

[0114] The following describes the specific circuit implementation.

[0115] See also Figure 7 , which is a schematic diagram of the circuit structure provided in an embodiment of the present application.

[0116] Figure 7 The power conversion circuit 105 is specifically a self-excited oscillation circuit, including a transistor Q1, a resistor R1 and a switch K1. The power supply D1 can be a battery of the smart watch or a battery voltage that is stepped up or stepped down.

[0117] The smartwatch controller controls the on / off state of switch K1, causing the self-oscillating circuit to output an alternating current to the first transmitting coil 13, thereby causing the first transmitting coil 13 to generate an alternating magnetic field. Switch K1 is a controllable switch, such as a relay, an insulated gate bipolar transistor (IGBT), a metal oxide semiconductor field effect transistor (MOSFET), a silicon carbide metal oxide semiconductor (SiC MOSFET), etc., and is not specifically limited in this embodiment of the present application. The operating principle of the self-oscillating converter is not described in detail in this embodiment of the present application.

[0118] The power conversion circuit 105 adopts Figure 7 In addition to the self-excited oscillation circuit shown in FIG, other self-excited oscillation circuits can also be used, such as Figure 8 The capacitor three-point oscillator shown. Figure 8 V in CC The DC voltage provided by the DC power supply.

[0119] The first conversion circuit 251 on the smart glasses includes a first detection circuit, which is a full-bridge detection circuit, also known as a full-bridge rectifier circuit, and includes bridge-connected diodes D11, D21, D31, and D41. When the smart watch and smart glasses are in close proximity, the alternating magnetic field generated by the first transmitting coil 13 causes the first receiving coil 21 to generate an alternating current. This alternating current is rectified into direct current by the full-bridge detection circuit. The direct current is converted into a voltage when it passes through resistor R21. This voltage serves as the output signal of the first conversion circuit 251, and the voltage value is output to the processor 211 of the smart glasses. When the first conversion circuit 251 and the processor 211 share a common ground, the voltage value output by the first conversion circuit 251 is the voltage value across resistor R21.

[0120] The input port of the first detection circuit is the positive pole of D11 and the positive pole of D21, which is used to connect to the output end of the first receiving coil 21. The output port of the first detection circuit is the negative pole of D11 and the negative pole of D21, and the output port is connected to R21 and the switch K11.

[0121] Similarly, the second detection circuit on the second conversion circuit 252 is a full-bridge detection circuit, including bridge-connected diodes D11, D21, D31 and D41. The alternating current generated by the second receiving coil 22 is rectified into direct current after passing through the full-bridge detection circuit. The direct current is converted into a voltage when passing through the resistor R22. This voltage serves as the output signal of the second conversion circuit 252, and the voltage value is output to the processor 211 of the smart glasses.

[0122] The first conversion circuit 251 is provided with a switch K11, and the second conversion circuit 252 is provided with a switch K22. K21 and K22 are controllable switches for controlling whether the corresponding conversion circuit can output a voltage value. When a user needs to use a smartwatch to control the smart glasses, the user triggers the corresponding control behavior on the smart glasses, causing K21 and K22 to close. Alternatively, K11 and K12 can be set to automatically close after the smart glasses are turned on. In another possible implementation, K21 and K22 can also be omitted.

[0123] The first conversion circuit 251 and the second conversion circuit 252 can be respectively arranged on the temples of the glasses on both sides, or can be arranged on the temples of the glasses on the same side at the same time, for example, they can be arranged on the temples of the glasses where the processor of the smart glasses is located. This embodiment of the present application does not make any specific limitations.

[0124] See also Figure 9 , this figure is a schematic diagram of the scene provided by this application Figure 2 .

[0125] The smartwatch's system application or system settings may include a query option for enabling the smart glasses control function. The user can proactively enable the smart glasses control function on the smartwatch. The smartwatch's processor 101 then controls K1 of the power conversion circuit 105 to switch from an off state to an on state, causing the power conversion circuit 105 to begin outputting AC power to the first transmitting coil 13.

[0126] When the user needs the smart glasses to implement corresponding functions, the user can bring the smart watch close to the smart glasses, so that the conversion circuit of the smart glasses outputs a voltage value to the processor 211 of the smart glasses.

[0127] It is understood that the solution of the present application is compatible with smart glasses with physical buttons, and can also be applied to smart glasses without physical buttons. For smart glasses with physical buttons, the first temple 231 and the second temple 232 are provided with buttons with different functions. Therefore, when the smart watch is close to the left side or the right side of the smart glasses, different functions can be triggered, thereby achieving coverage of various button functions.

[0128] See also Figure 10 and Figure 11 .in, Figure 10 Scenario provided for this application Figure 3 ; Figure 11 Scenario provided for this application Figure 4 .

[0129] After the user activates the smartwatch control function on their smartwatch, when they bring the smartwatch close to the smartglasses 20, the first transmitting coil of the smartwatch generates an alternating magnetic field. This allows both the first receiving coil 21 and the second receiving coil 22 to generate induced currents. The solution of this embodiment of the application aims to enable the control function corresponding to the button on the side to which the smartwatch is closer to the receiving coil.

[0130] Figure 10 and Figure 11 The smart glasses include a first receiving coil 21 and a second receiving coil 22. The first conversion circuit 251 is located on the first glasses leg 231, and the second conversion circuit 252 is located on the second glasses leg 232.

[0131] by Figure 10 For example, when the smart watch is closer to the left frame 241, that is, closer to the first receiving coil 21 on the left side, the distance between the first receiving coil 21 and the first transmitting coil of the smart watch is closer, and the smart watch can realize the function of the button on the first temple 231. Figure 11 For example, the smart watch is closer to the right frame 242 , that is, closer to the second receiving coil 11 on the right side. At this time, the smart watch can realize the function of the button on the second glasses leg 232 .

[0132] for Figure 10 In the scenario shown, when the smartwatch moves closer to the left frame 241, and therefore closer to the left first receiving coil 21, the user controls the smartwatch to perform a combination of actions corresponding to the target function, causing the processor to receive a varying voltage value and, based on the voltage value, to perform the function of the button on the first temple 231. The functions of the buttons corresponding to the first temple 231 can be referred to as a first set of functions. Alternatively, the first set of functions may include only the functions of some of the buttons on the first temple 231.

[0133] In the solution of the embodiment of the present application, the user controls the number of times the smart watch approaches the smart glasses and the duration of each approach to the smart glasses to obtain different action combinations. The action combination can include one or more actions. Figure 10 Give an example.

[0134] The first temple 231 includes a play / pause button 202, a volume reduction button 203, and a volume increase button 204. At this time, the first group of functions includes the play / pause button, the volume reduction button, and the volume increase button.

[0135] For example, the voltage output by the first conversion circuit can be set to cause the processor to press the play / pause button 202 once when the smart watch is briefly brought into proximity with the first receiving coil 21 once, that is, to briefly bring the smart watch into proximity with the left frame 241 once. The voltage output by the first conversion circuit can be set to cause the processor to press the volume down button 203 once when the smart watch is briefly brought into proximity with the first receiving coil 21 twice in a row. The voltage output by the first conversion circuit can be set to cause the processor to press the volume up button 204 once when the smart watch is brought into proximity with the first receiving coil 21 for a first period of time.

[0136] The embodiments of the present application do not impose specific restrictions on the duration of a brief proximity to the receiving coil, the time interval between two adjacent proximity to the receiving coil, or the first time period. For example, the proximity time can be set to the second time period to be considered as a brief proximity to the first receiving coil, with the second time period being 0.5s-1.5s; the proximity time of each of the two consecutive brief proximity to the receiving coil is the second time period, with the interval in between being the third time period, which can also be set to 0.5-1.5s; the first time period of the smartwatch approaching the receiving coil multiple times is set to 3s-5s, for example, it can be set to 4s.

[0137] In one possible implementation, the processor may use the value of the first parameter X to represent the number of times the watch briefly approaches the first receiving coil, and use the value of the second parameter Z to represent the number of times the watch approaches the first receiving coil for a first period of time. The correspondence between the parameter value combination and the first set of functions may be shown in Table 1 below.

[0138] Table 1: Correspondence between parameter value combinations and the first group of functions

[0139]

[0140] The processor detects the voltage value output by the conversion circuit to determine a first parameter value combination, and matches a first function corresponding to the first parameter value combination from the first group of functions. For example, when the first parameter X is determined to be 1 and the second parameter Z is 0, the function of pressing the play / pause key 202 once is implemented. When the first parameter X is determined to be 2 and the second parameter Z is 0, the function of pressing the volume down key 203 once is implemented. When the second parameter Z is determined to be 1 and the first parameter X is 0, the function of pressing the volume up key 204 once is implemented.

[0141] When the first voltage value is greater than or equal to the voltage threshold, the processor determines a first parameter value combination based on the duration that the first voltage value is greater than or equal to the voltage threshold, and the duration that the first voltage value is less than the voltage threshold after being greater than or equal to the voltage threshold. Specifically, the processor of the smart glasses begins timing when the first voltage value output by the first conversion circuit is greater than or equal to the voltage threshold. If the first voltage value is greater than or equal to the voltage threshold for a duration within the second time period, the smart glasses are deemed to be in close proximity to the first receiving coil 21, and the X value is incremented by 1. If the first voltage value is greater than or equal to the voltage threshold for a duration within the first time period, the smart glasses are deemed to have been in close proximity to the first receiving coil 21 for a long period of time, and the Z value is incremented by 1. Through continuous detection, the parameter values of X and Z are continuously updated.

[0142] When, after the first voltage value is greater than or equal to the voltage threshold, the first time the first voltage value is less than the voltage threshold and the duration exceeds a third period, the smartwatch's current action combination is considered complete. The corresponding key function is then implemented based on the recognition result, and the X and Z values are reset to their initial values. The voltage threshold can be pre-calibrated through testing and stored in the smart glasses' memory for later use.

[0143] In this implementation, the action of the smart watch is identified by using the detection result of the voltage value output by the conversion circuit.

[0144] In the embodiment of the present application, there is no specific limitation on the voltage threshold, for example, it can be set to 1V or 2V. It is understandable that in order to avoid the first voltage value and the second voltage value being greater than the voltage threshold at the same time, the voltage threshold can be set larger through actual testing, so that when the first voltage value is greater than or equal to the voltage threshold, since the smart watch is closer to the first receiving coil at this time, the second voltage value is smaller relative to the second receiving coil, and will not simultaneously meet the requirement of being greater than or equal to the voltage threshold, thereby ensuring that the smart glasses achieve a unique and determined function.

[0145] for Figure 11 In the scenario shown, when the smartwatch is closer to the right frame 242, that is, closer to the second receiving coil 22 on the right side, the second voltage value output by the second conversion circuit is greater than or equal to the voltage threshold, and the first voltage value output by the first conversion circuit is less than or equal to the voltage threshold. Therefore, the processor of the smartwatch implements the function of the button on the second temple 232 based on the action combination of the smartwatch at this time. The functions of each button corresponding to the second temple 232 can be referred to as the second group of functions. Alternatively, the second group of functions may include only the functions of some buttons on the second temple 232.

[0146] The second glasses leg 232 includes a power button 205, a camera button 206 and a video button 207. At this time, the second group of functions includes power control (i.e., power on / off control), camera and video.

[0147] For example, when the smartwatch is briefly brought into close proximity with the second receiving coil 22 once, that is, when the right frame 242 is briefly brought into close proximity with the second frame, the voltage output by the second conversion circuit can cause the processor to press the camera button 206 once. When the smartwatch is briefly brought into close proximity with the second receiving coil 22 twice in a row, the voltage output by the second conversion circuit can cause the processor to press the video button 207 once. When the smartwatch is brought into close proximity with the second receiving coil 22 for a first period of time, the voltage output by the second conversion circuit can cause the processor to perform a function equivalent to pressing the power button 205. In this implementation, the set of action combinations corresponding to the buttons on the second temple 232 is the same as the set of action combinations corresponding to the buttons on the first temple 231. That is, each action combination functions as a different button on each side, reducing user operational difficulty and the number of action combinations the user needs to memorize.

[0148] In this case, the processor can use the parameter value of the first parameter X to represent the number of times the watch briefly approaches the first receiving coil (i.e., the duration of the approach to the first receiving coil is the second time period), and use the parameter value of the second parameter Z to represent the number of times the watch approaches the first receiving coil for the first time period. The correspondence between the parameter value combination and the second set of functions can be shown in Table 2 below.

[0149] Table 2: Correspondence between parameter value combinations and the second group of functions Table 1

[0150]

[0151] The processor detects the voltage value output by the conversion circuit to determine a second parameter value combination, and matches a second function corresponding to the second parameter value combination from the second set of functions. For example, when the first parameter X is determined to be 1 and the second parameter Z is 0, the processor controls the smart glasses to implement the function of pressing the camera button 202 once.

[0152] When the second voltage value is greater than or equal to the voltage threshold, the processor determines a second parameter value combination based on the duration that the second voltage value is greater than or equal to the voltage threshold, and the duration that the second voltage value is less than the voltage threshold after being greater than or equal to the voltage threshold. Specifically, the processor of the smart glasses begins timing after the second voltage value output by the second conversion circuit is greater than or equal to the voltage threshold. If the second voltage value is greater than or equal to the voltage threshold for a duration within the second time period, the smart glasses are deemed to be in close proximity to the first receiving coil 21, and the X value is incremented by 1. If the second voltage value is greater than or equal to the voltage threshold for a duration within the first time period, the smart glasses are deemed to have been in close proximity to the first receiving coil 21 for a long period of time, and the Z value is incremented by 1. Through continuous detection, the parameter values of X and Z are continuously updated.

[0153] When, after the second voltage value is greater than or equal to the voltage threshold, the second voltage value is less than the voltage threshold for the first time and lasts longer than a third period of time, the smartwatch's current action combination is considered complete. The corresponding key function is then implemented based on the recognition result, and the X and Z values are reset to their initial values. The voltage threshold can be pre-calibrated through testing and stored in the smart glasses' memory for later use.

[0154] In addition, different sides can also have different action combinations, such as Figure 11 In this scenario, the voltage output by the second conversion circuit can be set to cause the processor to perform a function equivalent to pressing the power button 205 when the smartwatch is in close proximity to the second receiving coil 22 for a first period of time. Alternatively, the voltage output by the second conversion circuit can be set to cause the processor to perform a function equivalent to pressing the record button 207 once when the smartwatch is briefly in close proximity to the second receiving coil 22 three times in a row. Alternatively, the voltage output by the second conversion circuit can be set to cause the processor to perform a function equivalent to pressing the photo button 206 once when the smartwatch is briefly in close proximity to the second receiving coil 22 once and then in close proximity to the second receiving coil for a longer period of time. The corresponding relationship between the parameter value combinations and the second set of functions can be shown in Table 3 below.

[0155] Table 3: Correspondence between parameter value combinations and the second group of functions Table 2

[0156]

[0157] It should be understood that the above action combinations in the embodiments of the present application are merely examples, that is, the correspondence between the parameter value combinations and the first set of functions, and the correspondence between the parameter value combinations and the second set of functions are merely examples, and do not constitute a limitation on the technical solution of the present application. The function of each button may also correspond to other parameter value combinations, which are not described in detail in this embodiment. The magnitude of each voltage value in the description of this application may be an effective value or an amplitude value.

[0158] In addition, the first and second groups of functions may overlap in whole or in part. For example, the second group of functions may include the "function corresponding to the play / pause button" in the first group of functions. In this case, the parameter combination value corresponding to the "function corresponding to the play / pause button" may be the same as or different from that in Table 1. However, it should be noted that it is necessary to ensure that this parameter combination value does not correspond to other functions in the second group of functions.

[0159] The above functions are only examples and do not constitute a limitation on the technical solution of this application. Other functions can also be realized, such as switching to the next song, returning to the previous song, recording, translation, etc.

[0160] The smart glasses can compare the voltage value output by the conversion circuit with the voltage threshold using a voltage comparator. For example, the smart glasses include a first voltage comparator and a second voltage comparator. The first voltage comparator is used to compare the first voltage value with the voltage threshold, and the second voltage comparator is used to compare the second voltage value with the voltage threshold.

[0161] In summary, the solution provided by the embodiments of the present application can control smart glasses via a smart watch. Since the smart watch only needs to generate a simple alternating current, a simple self-excited oscillation circuit can be used. This circuit takes up little space in the smart watch and thus does not substantially affect the size of the smart watch. After the alternating current passes through the transmitting coil, the transmitting coil can generate an alternating magnetic field. When the smart watch is close to the smart glasses, the receiving coil of the smart glasses generates an alternating current, thereby achieving control of the smart glasses. This solution does not require the user to click buttons on the smart glasses, avoiding accidental touches, nor does it require the user to control the smart glasses through voice control. Therefore, there is no need to use voice recognition technology or install relatively expensive supporting components. Even when the user is in an environment where speaking is not convenient, the smart glasses can still be controlled normally. Therefore, this solution allows users to control smart glasses more conveniently, improving the user experience.

[0162] It is understandable that in actual applications, only one set of receiving coils and one conversion circuit can be set to realize the function of one of the buttons on the legs of the glasses, or the function of one or more selected buttons. At this time, the processor of the electronic device does not need to compare the voltage values output by the two conversion circuits, and can directly determine the corresponding function based on the action combination of the smart watch. The principle is similar to the above description and will not be repeated here.

[0163] In the above embodiments, the receiving coil is placed on the middle frame of the smart glasses. The area covered by the receiving coil is large, and thus the magnetic induction area is large, which helps reduce the transmission power of the transmitting coil on the smartwatch side. The following describes how to implement the placement of the receiving coil on the temple of the smart glasses.

[0164] See also Figure 12 , which is a schematic diagram of another type of smart glasses provided in an embodiment of the present application.

[0165] Figure 12 The implementation shown is similar to Figure 2 The difference is that: the first group of receiving coils 211 and the second group of receiving coils 221 each include multiple receiving coils, the first group of receiving coils 211 is arranged in the first temple 231 of the glasses, and the receiving coils of the first group of receiving coils 211 are arranged adjacent to each other; the second group of receiving coils 221 is arranged in the second temple 232 of the glasses, and the receiving coils of the second group of receiving coils 221 are arranged adjacent to each other.

[0166] The multiple receiving coils in each group can be connected in parallel. In this case, the AC power output by each receiving coil in the first group of receiving coils 211 is combined and output to the first conversion circuit, and the AC power output by each receiving coil in the second group of receiving coils 221 is combined and output to the second conversion circuit.

[0167] By providing multiple coils, the induction area is increased, thereby increasing the magnitude of the induced current.

[0168] In one possible implementation, the number of receiving coils provided in the first group of receiving coils 211 and the second group of receiving coils 221 is the same and their positions are symmetrical, and the sum of the areas enclosed by the receiving coils in the first group of receiving coils 211 is equal to the sum of the areas enclosed by the receiving coils in the second group of receiving coils 221.

[0169] The working principles of the first group of receiving coils 211 and the second group of receiving coils 221 can be found in the description of the above embodiments, and will not be elaborated in detail in the embodiments of the present application.

[0170] In the above implementation, by placing the receiving coils on the temples on both sides of the smart glasses, when the user controls the smart glasses through the smart watch, the smart watch can be placed close to the temples on both sides of the user's sight without blocking the user's sight, thus further improving the user experience. Figure 12 On the basis of Figure 2 The first receiving coil shown is also provided on the right frame. Figure 2 The second receiving coil is shown.

[0171] See also Figure 13 , this figure is a schematic diagram of another type of smart glasses provided in an embodiment of the present application.

[0172] Figure 12 The implementation shown is similar to Figure 12The difference is that the first group of receiving coils includes one receiving coil, namely the receiving coil 212, and the second group of receiving coils includes one receiving coil, namely the receiving coil 222.

[0173] The receiving coil 212 is disposed in the first temple 231 and is in a ring shape. The receiving coil 212 may be disposed along the edge of the first temple 231 to increase the magnetic induction area.

[0174] The receiving coil 222 is disposed in the second temple 232 and is in a ring shape. The receiving coil 222 can be disposed along the edge of the second temple 232 to increase the magnetic induction area.

[0175] In a possible implementation, the receiving coil 212 and the receiving coil 222 are symmetrically positioned, and the magnetic induction area of the receiving coil 212 is the same as the magnetic induction area of the receiving coil 222 .

[0176] In the above implementation, by placing the receiving coils on the temples on both sides of the smart glasses, when the user controls the smart glasses through the smart watch, the smart watch can be placed close to the temples on both sides of the user's sight without blocking the user's sight, thus further improving the user experience. Figure 13 On the basis of Figure 2 The first receiving coil shown is also provided on the right frame. Figure 2 The second receiving coil shown in FIG. 1 , the smart glasses at this time are as follows Figure 14 As shown, it can support users to use smart watches to realize button functions from the side or front of smart glasses, thereby adapting to the usage habits of different users.

[0177] Other implementations of setting a transmitting coil in a smart watch are described below.

[0178] See also Figure 15 , this figure is a schematic diagram of another smart watch provided in an embodiment of the present application.

[0179] Figure 15 The smartwatch shown is compatible with Figure 3 The difference is that the smart watch 10 includes a first set of transmitting coils 131, which includes multiple transmitting coils, and the first set of transmitting coils 131 is set on the strap 12. The number of transmitting coils included in the first set of transmitting coils 131 is greater than or equal to 4.

[0180] The first set of transmitting coils 131 can be set on the surface of the strap 12, or set inside the strap 12, which is not specifically limited in the embodiment of the present application.

[0181] In one possible implementation, the number of transmitting coils included in the first group of transmitting coils 131 is an even number, and the transmitting coils are evenly distributed on both sides of the watchband, with each transmitting coil being adjacent to each other. The number of transmitting coils included in each side of the watchband is the same.

[0182] Current can flow through each transmitting coil to increase the magnetic induction area.

[0183] See also Figure 16 , this figure is a schematic diagram of another smart watch provided in an embodiment of the present application.

[0184] Figure 16 The smartwatch shown is compatible with Figure 3 The difference is that the smart watch 10 includes a second set of transmitting coils 132, which includes two transmitting coils, and the second set of transmitting coils 132 is provided on the strap 12. Each side of the strap 12 includes a transmitting coil.

[0185] The second set of transmitting coils 132 can be set on the surface of the strap 12, or set inside the strap 12, which is not specifically limited in the embodiment of the present application.

[0186] In one possible implementation, one of the transmitting coils is arranged in a ring shape on the first side of the watch strap and is close to the outer edge of the first side of the watch strap, thereby increasing the magnetic induction area; the other transmitting coil is arranged in a ring shape on the second side of the watch strap and is close to the outer edge of the second side of the watch strap, thereby increasing the magnetic induction area.

[0187] The above embodiment sets the transmitting coil in the watch strap, thus avoiding occupying the space on the dial of the electronic watch due to the setting of the transmitting coil. In addition, when the dial of the smart watch adopts a metal shell, it can also avoid the shielding effect of the metal shell on the magnetic field and reduce the heat of the dial. In addition, the transmitting coil can be set on the dial and the strap at the same time, that is, 3 and Figure 16 Combine, or Figure 3 and Figure 16 Combination, I will not go into details again.

[0188] Based on the smart watches and smart glasses provided in the above embodiments, the embodiments of the present application also provide a control system for smart glasses, including the smart watches and smart glasses in the above embodiments. The principle of collaborative work between smart glasses and smart watches can be found in the description of the above embodiments and will not be repeated here.

[0189] In another possible implementation, the transmitting coil in the smartwatch, which serves as an energy transmitting device (also known as a power transmitting device), can also be replaced with a wire or an electrode. When the transmitting coil is replaced with an antenna, electromagnetic waves can be emitted to the outside, thereby causing the receiving coil on the smart glasses to generate an induced voltage. When the transmitting coil is replaced with an electrode, an induced electric field is generated by the electrode, and the induced electric field radiates electromagnetic waves to the outside, thereby causing the receiving coil on the smart glasses to generate an induced voltage. In addition, the receiving coil in the smart glasses, which serves as an energy receiving device (also known as a power receiving device), can also be replaced with an antenna or an electrode accordingly.

[0190] In yet another possible implementation, see Figure 17 , which is a schematic diagram of a control system of smart glasses provided in an embodiment of the present application.

[0191] Figure 17 In the implementation shown, the transmitting coil on the smart watch can be replaced by metal plates 1302 and 1303, for example. Figure 15 and Figure 16 The transmitting coil on the watchband is replaced with a metal plate. Specifically, the transmitting coil on one side of the watchband is replaced with metal plate 1302, and the transmitting coil on the other side of the watchband is replaced with metal plate 1303. When the user wears the smartwatch, the watchband is bent, and metal plates 1302 and 1303 face each other. Power conversion circuit 105 can still use a self-oscillating circuit to output a varying voltage.

[0192] After the transformed voltage is applied to the metal plate 1302 and the metal plate 1303, a changing electric field E1 is generated between the metal plate 1302 and the metal plate 1303, and E1 radiates outward to generate a changing electromagnetic wave.

[0193] The receiving coil of the smart glasses can be replaced with metal plates 1304 and 1305. For example, metal plates 1304 and 1305 can be placed on the first or second temple of the smart glasses. When the smartwatch gradually approaches the temple of the smart glasses, the electric field strength of the environment surrounding metal plates 1304 and 1305 gradually increases, and the induced electric field E0 increases. E0 is a changing electric field, which can generate a changing induced voltage between metal plates 1304 and 1305. The changing induced voltage is converted into a DC voltage after passing through the detection circuit 1306 and output to the processor 211, thereby implementing the corresponding control function.

[0194] In this implementation, each temple of the smart glasses includes two metal plates, enabling the smartwatch to perform corresponding control functions when approaching the temples from either side of the smart glasses. The principle by which processor 211 implements corresponding control functions based on voltage values can be found in the description of the above embodiments and will not be elaborated upon here. Furthermore, to increase the magnitude of the voltage output by processor 211 and facilitate voltage detection by the processor, the metal plates are placed on the temples in parallel and with the largest possible area. This is described in detail below with reference to the accompanying drawings.

[0195] See also Figure 18 , which is a schematic diagram of another type of smart glasses provided in an embodiment of the present application.

[0196] The receiving coil of the smart glasses is replaced with metal plates. Specifically, metal plates 1304 and 1305 are located above and below the first temple 231, and metal plates 1038 and 1037 are located above and below the second temple 232. For example, when a user wears a smart watch and approaches the first temple 231 from the left, the distance between metal plates 1302 and 1303 on the smart watch is greater than the distance between metal plates 1304 and 1305. The relative position relationship of the four metal plates at this time is shown in FIG. Figure 17 , thereby causing metal plates 1304 and 1305 to generate an alternating voltage, and the processor obtains a first voltage value. Similarly, metal plates 1038 and 1037 generate an alternating voltage, and the processor obtains a second voltage value. At this point, the first voltage value is greater than the second voltage value, and the smartwatch can control the smart glasses to implement the relevant functions of the buttons on the first temple 231.

[0197] Based on the smart watches and smart glasses provided in the above embodiments, the embodiments of the present application further provide a method for controlling smart glasses, which will be described in detail below with reference to the accompanying drawings.

[0198] See also Figure 19 , which is a flow chart of a control method for smart glasses provided in an embodiment of the present application.

[0199] For the specific implementation of smart glasses and smart watches, please refer to the relevant description in the above embodiments, and the embodiments of this application will not be repeated here. The method includes the following steps:

[0200] S21: The user turns on the control function of the smart glasses on the smart watch.

[0201] like Figure 9As shown, a query option for enabling the smart glasses control function can be set in the system application or system settings of the smart watch. The user can actively enable the smart glasses control function on the smart watch. After that, the processor 101 of the smart watch controls K1 of the power conversion circuit from the off state to the on state, so that the power conversion circuit begins to output AC power to the first set of transmitting coils.

[0202] The first set of transmitting coils in a smartwatch uses alternating current to generate an alternating magnetic field.

[0203] S22: Determine the sensing position and action combination corresponding to the target function from the correspondence between the action combination, the sensing position, and the function.

[0204] At this point, the user can determine the action combination and sensing location that match the target function based on the correspondence between the action combination, sensing location, and function, as well as the target function they currently want to achieve. Function refers to the function of the smart glasses, which may include functions corresponding to buttons on the smart glasses, or functions not available on buttons on the smart glasses. The target function, also known as the first smart glasses function, is the function that the user currently wants the smart glasses to achieve.

[0205] The sensing position represents the position of the first set of receiving coils or the second set of receiving coils. Figure 2 Taking the smart glasses shown as an example, the sensing position is the left frame or the right frame.

[0206] The action combination indicates the number of times the smart watch approaches the sensing location and the duration of each approach to the sensing location.

[0207] The following is an example with reference to Table 4.

[0208] Table 4: Correspondence between action combinations, sensing positions, and functions

[0209]

[0210] The above correspondence is for example only and does not limit the technical solution of this application. The duration corresponding to the short approach can be the second time period, for example, the second time period is 0.5s-1.5s; the duration corresponding to the long approach can be the first time period, for example, the first time period is 3s-5s.

[0211] When the action combination is completed, the smart watch should be controlled to stay away from the sensing position, and the duration of the stay is greater than the third time period, so that the smart glasses can determine that the action combination of the current smart watch has been completed.

[0212] The above correspondence can be recorded in the official product description of the smart watch or smart glasses, and can be memorized by the user. Alternatively, the user can set it according to their own habits or preferences.

[0213] It is understandable that the smart watch can control the functions of the smart glasses, but there may not be a corresponding button on the smart glasses. For example, the smart watch can control the smart glasses to realize the recording function, but there may not be a recording button on the smart glasses.

[0214] S23: Control the smart watch to complete the action combination so that the smart glasses can achieve the target function.

[0215] According to the sensing position corresponding to the target function, the user controls the smart watch to complete the action combination corresponding to the target function, causing the receiving coil of the smart glasses to generate an alternating current, thereby achieving control of the smart glasses.

[0216] This method does not require the user to click buttons on the smart glasses, thus avoiding accidental touches. It also does not require the user to control the smart glasses through voice control, thus eliminating the need for voice recognition technology or expensive supporting components. Even when the user is in an environment where speaking is not convenient, the smart glasses can still be controlled normally. Therefore, this solution allows users to control smart glasses more conveniently, improving the user experience.

[0217] It is understood that the division of the above steps is only for the convenience of explanation and does not constitute a limitation on the technical solution of this application. In actual application, the above steps can be adjusted. For example, when the control function of the smart watch for the smart glasses is configured to be automatically enabled, S21 may not be executed.

[0218] See also Figure 20 , which is a flowchart of another method for controlling smart glasses provided in an embodiment of the present application.

[0219] The method can be implemented by a processor of the smart glasses. The specific implementation and working principle of the smart glasses can be found in the description of the above embodiments and will not be repeated here. The method includes the following steps:

[0220] S41: Acquire a first voltage value output by the first conversion circuit and a second voltage value output by the second conversion circuit.

[0221] S42: Determine whether the first voltage value is greater than the second voltage value.

[0222] If so, execute S43; otherwise, it indicates that the current first voltage value is less than the second voltage value, and execute S47.

[0223] In an actual scenario where a user uses the solution of the present application, the first voltage value is generally not equal to the second voltage value.

[0224] S43: Determine a first parameter value combination according to a duration during which the first voltage value is greater than or equal to the voltage threshold, and a duration during which the first voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again.

[0225] When the first voltage value is greater than the second voltage value, the smart glasses are controlled according to the first voltage value to implement a first function in the first group of functions.

[0226] The first parameter value combination includes the parameter value of the first parameter X and the parameter value of the second parameter Z.

[0227] When the duration in which the first voltage value is greater than or equal to the voltage threshold is within the first time period, the parameter value of the second parameter is accumulated by 1.

[0228] When the duration in which the first voltage value is greater than or equal to the voltage threshold is within the second time period, the parameter value of the first parameter is accumulated by 1.

[0229] When the first voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than the third time period, it is considered that the execution of this action combination is completed, and the current parameter value of the first parameter and the current parameter value of the second parameter are used as the first parameter value combination, and the first time period is greater than the second time period.

[0230] The first time period is greater than the second time period.

[0231] S44: Match a first function corresponding to the first parameter value combination from the first group of functions.

[0232] The corresponding relationship between the parameter value combination and the first group of functions can be found in Table 1 above, which will not be repeated here.

[0233] S45: Reset the parameter value of the first parameter and the parameter value of the second parameter.

[0234] S46: Control the smart glasses to achieve the first function.

[0235] S47: Determine a second parameter value combination according to a duration during which the second voltage value is greater than or equal to the voltage threshold, and a duration during which the second voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again.

[0236] When the first voltage value is less than the second voltage value, the smart glasses are controlled according to the second voltage value to implement the second function in the second group of functions.

[0237] The second parameter value combination includes the parameter value of the first parameter X and the parameter value of the second parameter Z.

[0238] When the duration in which the second voltage value is greater than or equal to the voltage threshold is within the first time period, the parameter value of the second parameter is accumulated by 1.

[0239] When the duration in which the second voltage value is greater than or equal to the voltage threshold is within the second time period, the parameter value of the first parameter is accumulated by 1.

[0240] When the second voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than a third time period, the current parameter value of the first parameter and the current parameter value of the second parameter are combined as the second parameter value.

[0241] S48: Match a second function corresponding to the second parameter value combination from the second group of functions.

[0242] S49: Reset the parameter value of the first parameter and the parameter value of the second parameter.

[0243] S50: Control the smart glasses to realize the second function.

[0244] The first set of functions and the second set of functions include one or more of the following:

[0245] Take photos, record videos, power control, volume down, volume up, play, pause, record, switch to next song, return to previous song, translate.

[0246] The first set of functions and the second set of functions may be entirely or partially identical.

[0247] It is understood that the division of the above steps is for convenience of explanation only and does not constitute a limitation on the technical solution of this application. In actual applications, the above steps can be adjusted, for example, the order of S45 and S46 can be swapped to ensure that after the first function is realized, the parameter value is reset to start the recognition of the next function.

[0248] Through the above method, smart glasses can determine and implement corresponding functions based on voltage values. This eliminates the need for users to click buttons on the smart glasses, preventing accidental touches. It also eliminates the need for users to control the smart glasses through voice control, eliminating the need for voice recognition technology or expensive supporting components. Even when the user is in an environment where speaking is not convenient, the smart glasses can still be controlled normally. Therefore, this solution allows users to control smart glasses more conveniently, improving the user experience.

[0249] An embodiment of the present application further provides a method for controlling smart glasses, which determines the function implemented by the smart glasses by comparing a first voltage value and a second voltage value with a voltage threshold value, which is described in detail below with reference to the accompanying drawings.

[0250] See also Figure 21 , which is a flowchart of another method for controlling smart glasses provided in an embodiment of the present application.

[0251] After the user turns on the control function for the smart glasses on the smart watch, the smart watch generates an alternating magnetic field through the first set of transmitting coils. The user controls the smart watch to perform an action combination corresponding to the target action. For the smart glasses, the method includes the following steps:

[0252] S61: Acquire a first voltage value output by the first conversion circuit and a second voltage value output by the second conversion circuit.

[0253] S62: Determine whether the first voltage value is greater than or equal to a voltage threshold.

[0254] If so, execute S63, otherwise execute S67.

[0255] When the first voltage value is greater than or equal to the voltage threshold, it indicates that the first set of receiving coils is closer to the smartwatch, while the second set of receiving coils is relatively farther away from the smartwatch. To prevent the first and second voltage values from being simultaneously greater than the voltage threshold, the voltage threshold can be set higher through actual testing. This ensures that when the first voltage value is greater than or equal to the voltage threshold, the second voltage value is lower relative to the second receiving coil because the smartwatch is closer to the first receiving coil, preventing the voltage threshold from being simultaneously met, thereby ensuring that the smart glasses achieve a unique and determined function.

[0256] Therefore, when the first voltage value is greater than or equal to the voltage threshold, it means that the second voltage value is less than the voltage threshold, and the processor will execute S73.

[0257] S63: Determine a first parameter value combination according to a duration during which the first voltage value is greater than or equal to the voltage threshold, and a duration during which the first voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again.

[0258] When the first voltage value is greater than the second voltage value, the smart glasses are controlled according to the first voltage value to implement a first function in the first group of functions.

[0259] The first parameter value combination includes the parameter value of the first parameter X and the parameter value of the second parameter Z.

[0260] When the duration in which the first voltage value is greater than or equal to the voltage threshold is within the first time period, the parameter value of the second parameter is accumulated by 1.

[0261] When the duration in which the first voltage value is greater than or equal to the voltage threshold is within the second time period, the parameter value of the first parameter is accumulated by 1.

[0262] When the first voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than the third time period, it is considered that the execution of this action combination is completed, and the current parameter value of the first parameter and the current parameter value of the second parameter are used as the first parameter value combination, and the first time period is greater than the second time period.

[0263] The first time period is greater than the second time period.

[0264] S64: Match a first function corresponding to the first parameter value combination from the first group of functions.

[0265] The corresponding relationship between the parameter value combination and the first group of functions can be found in Table 1 above, which will not be repeated here.

[0266] S65: Reset the parameter value of the first parameter and the parameter value of the second parameter.

[0267] In one possible implementation, the parameter value of the first parameter and the parameter value of the second parameter are both 0 after being reset.

[0268] S66: Control the smart glasses to achieve the first function.

[0269] S67: The smart glasses are not controlled to achieve the first function.

[0270] At this time, the processor is equivalent to discarding the acquired first voltage value and does not use the first voltage value to implement a specific control function.

[0271] S68: Determine whether the second voltage value is greater than or equal to the voltage threshold.

[0272] If so, execute S69, otherwise execute S73.

[0273] When the second voltage value is greater than or equal to the voltage threshold, it indicates that the second set of receiving coils is closer to the smart watch, and the first set of receiving coils is relatively far away from the smart watch, which means that the first voltage value is less than the voltage threshold, and the processor will execute S67.

[0274] S69: Determine a second parameter value combination according to a duration during which the second voltage value is greater than or equal to the voltage threshold, and a duration during which the second voltage value is greater than or equal to the voltage threshold and then becomes less than the voltage threshold again.

[0275] When the first voltage value is less than the second voltage value, the smart glasses are controlled according to the second voltage value to implement the second function in the second group of functions.

[0276] The second parameter value combination includes the parameter value of the first parameter X and the parameter value of the second parameter Z.

[0277] When the duration in which the second voltage value is greater than or equal to the voltage threshold is within the first time period, the parameter value of the second parameter is accumulated by 1.

[0278] When the duration in which the second voltage value is greater than or equal to the voltage threshold is within the second time period, the parameter value of the first parameter is accumulated by 1.

[0279] When the second voltage value is greater than or equal to the voltage threshold and then is less than the voltage threshold again for a duration greater than a third time period, the current parameter value of the first parameter and the current parameter value of the second parameter are combined as the second parameter value.

[0280] S70: Match a second function corresponding to the second parameter value combination from the second group of functions.

[0281] S71: Reset the parameter value of the first parameter and the parameter value of the second parameter.

[0282] In one possible implementation, the parameter value of the first parameter and the parameter value of the second parameter are both 0 after being reset.

[0283] S72: Control the smart glasses to implement the second function.

[0284] S73: Do not control the smart glasses to implement the second function.

[0285] At this time, the processor is equivalent to discarding the acquired second voltage value and does not use the second voltage value to implement a specific control function.

[0286] It should be understood that the division of the above steps is for ease of explanation only and does not constitute a limitation on the technical solution of this application. In actual applications, the above steps can be adjusted. For example, the order of S65 and S66 can be swapped to ensure that the parameter value is reset after the first function is realized to start the recognition of the next function. Alternatively, the order of S71 and S72 can be swapped to ensure that the parameter value is reset after the second function is realized to start the recognition of the next function.

[0287] In summary, the method provided in the embodiment of the present application is that the processor implements the corresponding control function according to the voltage value. Among them, the first function implemented when the first voltage value is greater than or equal to the voltage threshold, and the second function implemented when the second voltage value is greater than or equal to the voltage threshold belong to two groups of functions respectively. The first group of functions and the second group of functions may be completely different or partially the same. This solution does not require the user to click on the buttons on the smart glasses, avoiding accidental touches, nor does it require the user to control the smart glasses through voice control. Therefore, there is no need to use voice recognition technology or to carry more expensive supporting devices. When the user is in an environment where it is not convenient to speak, the smart glasses can still be controlled normally. Therefore, this solution enables users to control smart glasses more conveniently, improving the user experience.

The computer-readable storage medium can be any available medium capable of storing data on a computing device, or a data storage device such as a data center containing one or more available media.

In other embodiments, other wearable smart devices can also be used to control smart glasses, such as smart bracelets, smart rings, etc. Or other electronic devices can be used to control smart glasses, such as mobile phones.
