Technical Field

[0001] The embodiments of the present application relate to the technical field of device control, and in particular, to a pair of glasses. Background Art

[0002] Currently, electronic devices such as televisions on the market generally match a remote control to achieve close-range page control, such as browsing, turning pages, selecting, etc. However, during movie viewing, users may not be able to control the television as they like because the remote control is not at hand, which obviously reduces the user's movie viewing experience. Summary of the Invention

[0003] The present application provides a pair of glasses, so that after the user wears the glasses, the user can accurately control the electronic device having a binding relationship with the glasses as he likes.

[0004] In a first aspect, the embodiments of the present application provide a pair of glasses, which include lenses, an induction layer, an isolation layer, and a controller; the induction layer and the isolation layer are respectively arranged on different side mirrors of the lenses, and the induction layer is connected to the controller; the induction layer detects the self-capacitance value of the side mirror where the induction layer is located through the self-capacitance detection method, and the isolation layer is used to isolate the self-capacitance interference of the side mirror where the isolation layer is located; the controller is configured to: obtain the self-capacitance value detected by the induction layer; determine a control instruction for the controlled device according to the self-capacitance value; the control instruction is used to control the controlled device, and the controlled device has a binding relationship with the glasses.

[0005] In the above solution, for the glasses designed with an induction layer and an isolation layer, the self-capacitance value corresponding to the user's related behavior is detected through the induction layer on the glasses, so that after the controller on the glasses obtains the self-capacitance value, the controlled device paired with the glasses can be controlled according to the preset control relationship; in this solution, by introducing an isolation layer, since the isolation layer can isolate the self-capacitance interference of the side mirror where it is located, the detection result of the induction layer can be made more accurate, improving the accuracy of device control.

[0006] In a possible implementation method, the induction layer is arranged on the outer side mirror of at least one lens, and the induction layer includes at least two induction zones arranged in a set pattern; the induction layer detects the self-capacitance value corresponding to the hand movement on the outer side mirror through the self-capacitance detection method; the controller is specifically configured to: determine the control instruction corresponding to the hand movement on the outer side mirror according to the change trend of the self-capacitance values of different induction zones; wherein, the corresponding relationship between the control instruction and the hand movement is preset in the controller.

[0007] In the above solution, by designing the induction layer on the outer mirror surface of the lens and partitioning the induction layer according to a set pattern, the self-capacitance value generated by the movement of the user's hand relative to the mirror surface can be detected through the designed induction layer, so that the effect of controlling the controlled device through the movement of the user's hand can be achieved.

[0008] In a possible implementation method, the induction layer includes at least two induction partitions arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first induction partition is consistent with the second change trend of the second self-capacitance value detected by the second induction partition, and the first time period forming the first change trend is different from the second time period forming the second change trend, then determine that the control instruction is the first control instruction corresponding to the hand movement of moving up and down; wherein, the first induction partition and the second induction partition are located on the same lens; if it is determined that the first change trend is consistent with the second change trend, and the first time period coincides with the second time period, then determine that the control instruction is the second control instruction corresponding to the hand movement of telescopic movement.

[0009] In the above solution, it is specifically described that the induction layer with at least two induction partitions in the vertical direction determines two different user hand movements through the change trend of the detected self-capacitance value and the time when the change trend occurs, so that corresponding control of the controlled device can be achieved based on different hand movements.

[0010] In a possible implementation method, the induction layer includes at least two induction partitions arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first induction partition is consistent with the third change trend of the third self-capacitance value detected by the third induction partition, and the first time period of the first change trend is different from the third time period forming the third change trend, then determine that the control instruction is the third control instruction corresponding to the hand movement of horizontal movement; wherein, the first induction partition is located on the first lens, the third induction partition is located on the second lens, and the first induction partition and the third induction partition are horizontally arranged.

[0011] In the above solution, it is specifically described how the induction layer with at least two induction partitions in the vertical direction identifies the action of the user's hand moving horizontally relative to the user's eyes, so that after accurate identification, corresponding control of the controlled device can be performed based on the horizontal hand movement.

[0012] In a possible implementation method, the induction layer includes at least two induction partitions arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first induction partition, the second change trend of the second self-capacitance value detected by the second induction partition, the third change trend of the third self-capacitance value detected by the third induction partition, and the fourth change trend of the fourth self-capacitance value detected by the fourth induction partition are consistent, and the first time period forming the first change trend, the second time period forming the second change trend, the third time period forming the third change trend, and the fourth time period forming the fourth change trend are different from each other, then determine that the control instruction is the fourth control instruction corresponding to the hand movement of the circular motion; wherein, the first induction partition and the second induction partition are located on the first lens, the third induction partition and the fourth induction partition are located on the second lens, and the first induction partition and the third induction partition are in a horizontally arranged relationship, and the second induction partition and the fourth induction partition are in a horizontally arranged relationship.

[0013] In the above solution, it is specifically described how the induction layer with at least two induction partitions in the vertical direction identifies the action of the user's hand making a circular motion relative to the user's eyes, so that after accurate identification, the controlled device can be correspondingly controlled based on the hand movement of the circular motion.

[0014] In a possible implementation method, the induction layer is provided on the inner mirror surface of at least one lens, and the induction layer at least includes at least two induction partitions arranged in a set pattern; the induction layer detects the self-capacitance value corresponding to the eye movement of the inner mirror surface through the self-capacitance detection method; the controller is specifically configured to: determine the control instruction corresponding to the eye movement of the inner mirror surface according to the change trend of the self-capacitance values of different induction partitions; wherein, the corresponding relationship between the control instruction and the eye movement is pre-set in the controller.

[0015] In the above solution, by designing the induction layer on the inner mirror surface of the lens and partitioning the induction layer according to a set pattern, the self-capacitance value generated by the movement of the user's eyes relative to the mirror surface can be detected through the designed induction layer, so that the effect of controlling the controlled device through the user's eye movement can be achieved.

[0016] In a possible implementation method, the induction layer includes at least two induction partitions arranged in the vertical direction; the controller is specifically configured to: determine the eye closing rate of the inner mirror surface according to the self-capacitance change rate of the first self-capacitance value and the second self-capacitance value respectively detected by the first induction partition and the second induction partition; wherein, the first induction partition and the second induction partition are located on the same lens; if it is determined that the eye closing rate meets the set requirements, then determine that the control instruction is the control instruction corresponding to the eye movement of an effective blink.

[0017] In the above solution, it is specifically described that the sensing layer on the lens is partitioned in the vertical direction. In this way, when detecting the effectiveness of the user's eye-closure action, that is, when detecting whether the user's eye-closure behavior is effective (because it is also possible that the user blinks inadvertently rather than really making an eye movement to control the device), it will be possible to identify effective blinks and ineffective blinks, avoiding misidentification and improving the accuracy of device control.

[0018] In a possible implementation method, the controller is specifically configured to: determine the corresponding control instruction according to the number of effective blinks.

[0019] In the above solution, after detecting that the user's eye-closure behavior is effective, by further determining the number of times the user blinks, corresponding controls are executed on the controlled device according to different numbers of blinks.

[0020] In a possible implementation method, a ground loop isolation layer is provided in the first connection area between different sensing partitions and the second connection area between the sensing layer and the isolation layer.

[0021] In the above solution, by providing a ground loop isolation layer in both the connection area between different sensing partitions and the connection area between the sensing layer and the isolation layer, this will effectively reduce the interference of external factors on the sensing layer when detecting the self-capacitance value, and improve the accuracy of the sensing layer detection.

[0022] In a possible implementation method, it further includes a signal generator, and the signal generator is connected to the controller; the controller is specifically configured to: send a corresponding control signal to the signal generator according to the control instruction for the controlled device; the signal generator is used to receive the control signal, convert the control signal into an infrared electromagnetic signal and release it externally; the infrared electromagnetic signal is used to control the operation of the controlled device.

[0023] In the above solution, after the controller on the glasses determines the control instruction for the controlled device, in order to implement the control of the controlled device, the controller can send a corresponding control signal to the signal generator on the glasses that is connected to the controller based on the determined control instruction. Thus, after the signal generator receives this control signal, by converting it into an infrared electromagnetic signal and releasing it externally, the released infrared electromagnetic signal, after being received by the controlled device, will be able to execute the control instruction of the controller on the glasses for it, thereby meeting the user's control requirements for the controlled device.

[0039] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0040] Regarding the current solution that a remote control is required to control electronic devices such as televisions, since it is easy for users to lose the remote control for a moment, this significantly reduces the user experience of controlling the device.

[0041] To address the above technical problems, the present application provides a pair of glasses. For these glasses, the user can wear them during the process of watching TV. By wearing the glasses and performing certain actions on the glasses in a set manner, the relevant control of the television can be achieved, thus avoiding the embarrassing situation where the user cannot control the television because they cannot find the remote control for a moment.

[0042] As Figure 1 shown, it is a schematic diagram of a pair of glasses provided by an embodiment of the present application. The glasses include a frame 101, a lens 102, and a controller 103.

[0043] Among them, as an example, Figure 1 the lens 102 in

[0044] is a lens with a one-piece design, that is, it is not designed with an independent lens for each of the user's eyes. The lens 102 is embedded in the frame 101, and the controller 103 is arranged on the frame 101. Figure 1 Furthermore, for the lens 102, the lens 102 includes a sensing layer 1021 and an isolation layer 1022. As an example,

[0045] Among them, the sensing layer 1021 is connected to the controller 103. The sensing layer 1021 can detect the self-capacitance value of the mirror surface on its side through the self-capacitance detection method, and send the detected self-capacitance value to the controller 103 after detecting the self-capacitance value. Thus, the controller 103 determines the corresponding control instruction to control the controlled device. In the embodiment of the present application, in order to ensure the accuracy of the self-capacitance value detected by the sensing layer and avoid the self-capacitance interference from the other side mirror surface, the isolation layer is disposed on the mirror surface of the same lens and on the side opposite to the sensing layer, such as Figure 1 as shown in, the isolation layer 1022 is disposed on the inner mirror surface of the lens 102, and the sensing layer 1021 is disposed on the outer mirror surface of the lens 102.

[0046] Such as Figure 2 shown, it is a schematic diagram of a lens provided by the embodiment of the present application, where Figure 2 is the effect diagram of viewing the lens from the vertical angle. The outer sensing layer 1021 and the inner isolation layer 1022 are respectively disposed on both sides of the lens 102. The sensing layer 1021 and the isolation layer 1022 can adopt a transparent conductive material or MM (Metal Mesh), and the transparent conductive material can be ITO (Indium-Tin Oxide) material. In this way, while meeting the visual requirements of users, the control of the controlled device can also be realized.

[0047] It should be noted that Figure 2 in order to highlight that the sensing layer 1021 and the isolation layer 1022 are respectively located on both sides of the same lens, the thickness of the lens 102 is exaggeratedly reduced, and at the same time, the thickness of the sensing layer 1021 and the isolation layer 1022 is exaggeratedly enlarged.

[0048] Continuing to note that Figure 2 the lens shown in can also be selected based on the actual situation of the user's eyes. For example, if the user is a myopic person, the lens of the glasses in the embodiment of the present application will be a lens corresponding to the myopia degree; if the user is a hyperopic person, the lens of the glasses in the embodiment of the present application can also be a lens corresponding to the hyperopia degree; if the user is a person with normal vision, the lens of the glasses in the embodiment of the present application can be a transparent lens without degree. Among them, Figure 2 the color of the lens shown in can also be designed according to requirements, such as a colorless and transparent texture lens, or a color of any preference of the user.

[0049] The sensing layer is connected to the detection channel of the controller through FPC (Flexible Printed Circuit) or a wire( Figure 1(not shown in the figure) to detect the capacitance value change of the induction layer at a certain frequency; the isolation layer is connected to the logic ground wire of the controller through an FPC or a wire ( Figure 1 (not shown in the figure), which can shield the interference of external signals and make the data of the self-capacitance value obtained by the induction layer more accurate.

[0050] Based on Figure 1 the glasses shown, the controller 103 therein can execute the following device control method. As Figure 3 shown, it is a schematic diagram of a device control method provided by an embodiment of the present application. The method includes the following steps:

[0051] Step 301, obtain the self-capacitance value detected by the induction layer.

[0052] In this step, when the induction layer in the glasses detects the self-capacitance value through the self-capacitance detection method, the induction layer sends the detected self-capacitance value to the connected controller; correspondingly, the controller receives the self-capacitance value detected by the induction layer.

[0053] Step 302, determine a control instruction for the controlled device according to the self-capacitance value.

[0054] Wherein, the control instruction is used to control the controlled device, and the controlled device has a binding relationship with the glasses.

[0055] In this step, after the controller in the glasses obtains the self-capacitance value, it can determine a control instruction for the controlled device based on the self-capacitance value. The determined control instruction can control the controlled device, and the controlled device to be controlled has a pairing and binding relationship with the glasses.

[0056] In the above solution, for glasses designed with an induction layer and an isolation layer, the self-capacitance value corresponding to the user's related behavior is detected through the induction layer on the glasses. Thus, after the controller on the glasses obtains the self-capacitance value, it can control the controlled device paired with the glasses according to the preset control relationship; in this solution, by introducing the isolation layer, since the isolation layer can isolate the self-capacitance interference of the mirror surface on its side, the detection result of the induction layer can be made more accurate, improving the accuracy of device control.

[0057] Next, the solution of the present application will be described in detail with some examples.

[0058] In some embodiments of the present application, the outer mirror surface of at least one lens is provided with the induction layer, and the induction layer includes at least two induction partitions arranged in a set pattern; the induction layer detects the self-capacitance value corresponding to the hand movement on the outer mirror surface through a self-capacitance detection method; the controller is specifically configured to: determine the control instruction corresponding to the hand movement on the outer mirror surface according to the change trend of the self-capacitance values of different induction partitions; wherein, the correspondence between the control instruction and the hand movement is pre-set in the controller.

[0059] For example, when controlling a controlled device through the glasses provided by the present application, considering the factor that it can be based on the change of the self-capacitance value of the user's different hand movements on the induction layer of the glasses, in the present application, the induction layer can be arranged on the outer mirror surface of the lens, and at the same time, the induction layer is partitioned according to a set pattern to obtain corresponding multiple induction partitions. Among them, the set pattern can be, for example, dividing the induction partitions in the vertical direction, dividing the induction partitions in the horizontal direction, and designing the induction partitions in a circular ring pattern.

[0060] Such as Figure 4 shown, is a schematic diagram of a lens provided by an embodiment of the present application. Among them, only as an exemplary illustration, in the present application, only 2 induction partitions are divided for the induction layer of the lens, and the situation where the induction layer of the lens may further include 3 induction partitions, 4 induction partitions, and other numbers of induction partitions is not shown.

[0061] Figure 4 In (a), it represents a lens with induction partitions divided in the vertical direction. The outer mirror surface of this lens faces the user (the user here refers to the reader of this article). An induction layer is designed on this outer mirror surface. Further, this induction layer is divided into upper and lower two regions, and these upper and lower two regions are two induction partitions arranged in the vertical direction. For example, the induction partition with a higher position can be set as the first induction partition, and the induction partition with a lower position can be set as the second induction partition. Among them, when the induction layer on the outer mirror surface of the glasses is partitioned, each formed induction partition can separately detect the self-capacitance value of the user's hand during movement. Then, when the user's hand makes a movement near the induction layer with partition design, the control instruction corresponding to the user's hand movement can be determined based on the change trend of the self-capacitance values of different induction partitions. Among them, the correspondence between the control instruction and the hand movement has been pre-configured in the controller of the glasses. Thus, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's hand movement is. Therefore, based on the pre-configured correspondence between the control instruction and the hand movement, it can be known what the control instruction for controlling the controlled device corresponding to the user's current hand movement is.

[0062] Figure 4 In (b), it represents a lens with induction zone division in the horizontal direction. The outer mirror surface of this lens faces the user (the user here refers to the reader of this article). An induction layer is designed on this outer mirror surface. Further, this induction layer is divided into two regions, namely the left and right regions. These two left and right regions are two induction zones arranged in the horizontal direction. For example, the induction zone located on the left can be set as the first induction zone, and the induction zone located on the right can be set as the second induction zone. Among them, after the induction layer on the outer mirror surface of the glasses is divided into zones, each formed induction zone can separately detect the self-capacitance value of the user's hand during movement. Then, when the user's hand makes a movement near the induction layer with zone division, the control instruction corresponding to the user's hand movement can be determined based on the change trend of the self-capacitance values of the different induction zones. Among them, the corresponding relationship between the control instruction and the hand movement has been pre-configured in the controller of the glasses. Thus, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's hand movement is. Therefore, based on the pre-configured corresponding relationship between the control instruction and the hand movement, it can be known the control instruction for controlling the controlled device corresponding to the user's current hand movement.

[0063] Figure 4 In (c), it represents a lens with induction zone division in a circular ring manner. The outer mirror surface of this lens faces the user (the user here refers to the reader of this article). An induction layer is designed on this outer mirror surface. Further, this induction layer is divided into two regions, namely the inner circle and the outer circular ring. These two regions are two induction zones arranged in a circular ring pattern. For example, the induction zone at the position of the inner circle can be set as the first induction zone, and the induction zone at the position of the outer circular ring can be set as the second induction zone. Among them, after the induction layer on the outer mirror surface of the glasses is divided into zones, each formed induction zone can separately detect the self-capacitance value of the user's hand during movement. Then, when the user's hand makes a movement near the induction layer with zone division, the control instruction corresponding to the user's hand movement can be determined based on the change trend of the self-capacitance values of the different induction zones. Among them, the corresponding relationship between the control instruction and the hand movement has been pre-configured in the controller of the glasses. Thus, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's hand movement is. Therefore, based on the pre-configured corresponding relationship between the control instruction and the hand movement, it can be known the control instruction for controlling the controlled device corresponding to the user's current hand movement.

[0064] In some embodiments of the present application, the sensing layer includes at least two sensing zones arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first sensing zone is consistent with the second change trend of the second self-capacitance value detected by the second sensing zone, and the first time period during which the first change trend is formed is different from the second time period during which the second change trend is formed, then determine that the control instruction is a first control instruction corresponding to the hand movement of moving up and down; wherein, the first sensing zone and the second sensing zone are located on the same lens; if it is determined that the first change trend is consistent with the second change trend, and the first time period coincides with the second time period, then determine that the control instruction is a second control instruction corresponding to the hand movement of telescopic movement.

[0065] For example, based on Figure 4 the lens shown in (a) below, assuming that the sensing zone closer to the top is the first sensing zone and the sensing zone closer to the bottom is the second sensing zone. When the user places their hand in front of their glasses and moves their hand up and down in the vertical direction, for example, when the user moves their hand from top to bottom, the self-capacitance value detected by the first sensing zone of the sensing zone on the outer surface of the lens will gradually increase and then decrease, and the self-capacitance value detected by the second sensing zone will gradually increase and then decrease. Moreover, the time when the self-capacitance value detected by the first sensing zone changes is earlier than the time when the self-capacitance value detected by the second sensing zone changes. Then, when the sensing layer sends the information of this self-capacitance value change to the controller in the glasses, the controller can determine, by analyzing the information of this self-capacitance value change, that the user's hand movement is moving up and down in the vertical direction. Thus, the controller can determine the user's such hand movement by comparing it with the pre-configured correspondence between the control instruction and the hand movement. For example, by comparison, it is determined that the control instruction corresponding to the movement of the user's hand moving up and down in the correspondence is the control instruction for adjusting the volume. Thus, the controller can determine that the user wants to adjust the volume of the controlled device this time. After that, the controller can send a control instruction for volume adjustment to the controlled device.

[0066] Another example, based on Figure 4For the lens shown in (a) therein, the induction zone located higher is set as the first induction zone, and the induction zone located lower is set as the second induction zone. When the user places their hand in front of their glasses and moves their hand back and forth in the line of sight of their eyes, for example, the user moves their hand from far to near and back and forth, then the self-capacitance value detected by the first induction zone of the induction zones on the outer mirror surface of the lens will gradually increase and then decrease, and the self-capacitance value detected by the second induction zone will gradually increase and then decrease. Moreover, the time when the self-capacitance value detected by the first induction zone changes is almost the same as the time when the self-capacitance value detected by the second induction zone changes. Then, when the induction layer sends the information of this self-capacitance value change to the controller in the glasses, the controller analyzes the information of this self-capacitance value change and will be able to determine that the user's hand movement is moving their hand back and forth in the line of sight. Thus, the controller compares the user's such hand movement with the corresponding relationship between the pre-configured control instructions and the hand movement. For example, through comparison, it is determined that the control instruction corresponding to the movement of the user's hand moving back and forth in the front and back direction in the corresponding relationship is the control instruction for page magnification and reduction. Thus, the controller will be able to determine that the user wants to adjust the zoom of the page of the controlled device this time. After that, the controller will be able to send a control instruction for page zoom adjustment to the controlled device.

[0067] In some embodiments of the present application, the induction layer includes at least two induction zones arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first induction zone is consistent with the third change trend of the third self-capacitance value detected by the third induction zone, and the first time period of the first change trend is different from the third time period forming the third change trend, then determine that the control instruction is the third control instruction corresponding to the hand movement of horizontal movement; wherein, the first induction zone is located on the first lens, the third induction zone is located on the second lens, and the first induction zone and the third induction zone are in a horizontally arranged relationship.

[0068] As Figure 5As shown in the figure, it is a schematic diagram of a pair of glasses provided by an embodiment of the present application. The glasses include two lenses. Among them, on the outer mirror surfaces of the two lenses facing the user, induction layers are designed. At this time, the left lens is set as the first lens and the right lens is set as the second lens. Thus, the first induction area can be the induction layer designed on the left lens, and the third induction area can be the induction layer designed on the right lens. At this time, if the user places their hand in front of their glasses and moves their hand back and forth in the order from right to left, then the self-capacitance value detected by the induction layer on the outer mirror surface of the right lens (i.e., the third induction area) will gradually increase and then decrease, and the self-capacitance value detected by the induction layer on the outer mirror surface of the left lens (i.e., the first induction area) will gradually increase and then decrease. Moreover, the time when the self-capacitance value detected by the first induction area changes is later than the time when the self-capacitance value detected by the third induction area changes. Then, when the induction layer sends the information of this kind of self-capacitance value change to the controller in the glasses, the controller analyzes the information of this kind of self-capacitance value change and will be able to determine that the user's hand movement is to move their hand horizontally back and forth in front of the eyes. Thus, the controller compares the user's such hand movement with the corresponding relationship between the pre-configured control instructions and the hand movement. For example, through comparison, it is determined that the control instruction corresponding to the movement of the user's hand moving horizontally in front of the eyes in the corresponding relationship is the control instruction for page up and down flipping. Thus, the controller will be able to determine that the user wants to adjust the page flipping of the controlled device this time. After that, the controller will be able to send the control instruction for page up and down flipping to the controlled device.

[0069] For another example, as Figure 6As shown in the figure, it is a schematic diagram of a pair of glasses provided by an embodiment of the present application. The glasses include two lenses. Among them, on the outer mirror surfaces of the two lenses facing the user, induction layers are designed. At this time, the left lens is set as the first lens, and the right lens is set as the second lens. Further, for the left lens, it can be partitioned in the vertical direction. For example, the induction partition with a higher position is set as the first induction partition. Similarly, for the right lens, it is partitioned in the vertical direction. For example, the induction partition with a higher position is set as the third induction partition. Among them, the area sizes of the first induction partition and the third induction partition should be similar. At this time, if the user places his hand in front of his glasses and moves his hand back and forth in the order from right to left, then the self-capacitance value detected by the induction layer (i.e., the third induction partition) on the outer mirror surface of the right lens will gradually increase and then decrease. The self-capacitance value detected by the induction layer (i.e., the first induction partition) on the outer mirror surface of the left lens will gradually increase and then decrease. And the time when the self-capacitance value detected by the first induction partition changes is later than the time when the self-capacitance value detected by the third induction partition changes. Then when the induction layer sends the information of this self-capacitance value change to the controller in the glasses, the controller analyzes the information of this self-capacitance value change and will be able to determine that the user's hand movement is to move his hand horizontally back and forth in front of the eyes. Thus, the controller compares the user's such hand movement with the corresponding relationship between the pre-configured control instructions and the hand movement. For example, through comparison, it is determined that the control instruction corresponding to the movement of the user's hand horizontally in front of the eyes in the corresponding relationship is the control instruction for left and right page turning. Thus, the controller will be able to determine that the user wants to adjust the page turning of the controlled device this time. And after that, the controller will be able to send a control instruction for left and right page turning of the page to the controlled device.

[0070] In some implementations of the present application, the induction layer includes at least two induction partitions arranged in the vertical direction; the controller is specifically configured to: if it is determined that the first change trend of the first self-capacitance value detected by the first induction partition, the second change trend of the second self-capacitance value detected by the second induction partition, the third change trend of the third self-capacitance value detected by the third induction partition, and the fourth change trend of the fourth self-capacitance value detected by the fourth induction partition are the same, and the first time period forming the first change trend, the second time period forming the second change trend, the third time period forming the third change trend, and the fourth time period forming the fourth change trend are different from each other, then determine that the control instruction is the fourth control instruction corresponding to the hand movement of a circular motion; where the first induction partition and the second induction partition are located on the first lens, the third induction partition and the fourth induction partition are located on the second lens, and the first induction partition and the third induction partition are in a horizontally arranged relationship, and the second induction partition and the fourth induction partition are in a horizontally arranged relationship.

[0071] Continue to refer toFigure 6 Further, the lower-positioned induction area in the left lens can be set as the second induction area, and the lower-positioned induction area in the right lens can be set as the fourth induction area. At this time, if the user places the palm of their right hand in front of their glasses and rotates their right hand in one direction (such as making a clockwise or counterclockwise circular fist), the self-capacitance value detected by the first induction area on the outer mirror surface of the left lens will gradually increase and then decrease. The self-capacitance value detected by the second induction area on the outer mirror surface of the left lens will gradually increase and then decrease. The self-capacitance value detected by the fourth induction area on the outer mirror surface of the right lens will gradually increase and then decrease. The self-capacitance value detected by the third induction area on the outer mirror surface of the right lens will gradually increase and then decrease. Moreover, the time when the self-capacitance value detected by the first induction area changes will be slightly earlier than the time when the self-capacitance value detected by the third induction area changes. The time when the self-capacitance value detected by the second induction area changes will be slightly earlier than the time when the self-capacitance value detected by the third induction area changes. The time when the self-capacitance value detected by the fourth induction area changes will be slightly earlier than the time when the self-capacitance value detected by the third induction area changes. Then, when the induction layer sends the information of this self-capacitance value change to the controller in the glasses, the controller can determine, by analyzing the information of this self-capacitance value change, that the user's hand movement is rotating their fingers in one direction in front of the eyes. Thus, the controller can determine, by comparing this hand movement of the user with the pre-configured correspondence between control instructions and hand movements. For example, by comparison, it is determined that the control instruction corresponding to the movement of rotating the fingers in one direction in front of the eyes of the user in the correspondence is the control instruction for channel switching. Thus, the controller can determine that the user wants to adjust the channel switching of the controlled device this time. After that, the controller can send a control instruction for switching channels to the controlled device.

[0072] In some embodiments of the present application, the induction layer is provided on the inner mirror surface of at least one lens. The induction layer at least includes at least two induction areas arranged in a set pattern. The induction layer detects the self-capacitance value corresponding to the eye movement on the inner mirror surface by means of self-capacitance detection. The controller is specifically configured to: determine the control instruction corresponding to the eye movement on the inner mirror surface according to the change trend of the self-capacitance value of different induction areas. Wherein, the correspondence between the control instruction and the eye movement is pre-set in the controller.

[0073] For example, when controlling a controlled device through the glasses provided by the present application, considering the factor that the self-capacitance value on the sensing layer of the glasses can change based on different eye movements of the user, in the present application, the sensing layer can be arranged on the inner mirror surface of the lens, and at the same time, the sensing layer is partitioned according to a set pattern to obtain a corresponding plurality of sensing partitions. Among them, the set pattern can be, for example, partitioning the sensing partitions in the vertical direction, partitioning the sensing partitions in the horizontal direction, or designing the sensing partitions in a circular ring pattern.

[0074] As Figure 7 shown, it is a schematic diagram of a lens provided by an embodiment of the present application. Among them, only for an exemplary illustration, in the present application, only 2 sensing partitions are divided for the sensing layer of the lens, and the situation where the sensing layer of the lens can also include 3 sensing partitions, 4 sensing partitions, and other numbers of sensing partitions is not shown.

[0075] Figure 7 In (a), it represents a lens with sensing partitions divided in the vertical direction. The inner mirror surface of this lens faces the user (the user here refers to the reader of this article). An sensing layer is designed on this inner mirror surface. Further, the sensing layer is divided into upper and lower two regions, and these upper and lower two regions are two sensing partitions arranged in the vertical direction. For example, the sensing partition with a higher position can be set as the first sensing partition, and the sensing partition with a lower position can be set as the second sensing partition. Among them, when the sensing layer on the inner mirror surface of the glasses is partitioned, each formed sensing partition can separately detect the self-capacitance value of the user's eyes during movement. Then, when the user's eyes make an action on the sensing layer with partition design, the control instruction corresponding to the user's eye movement can be determined based on the change trend of the self-capacitance value of each different sensing partition. Among them, the corresponding relationship between the control instruction and the eye movement has been pre-configured in the controller of the glasses. Thus, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's eye movement is, and thus, based on the pre-configured corresponding relationship between the control instruction and the eye movement, it can know the control instruction for controlling the controlled device corresponding to the user's current eye movement.

[0076] Figure 7Among them, (b) represents a lens with induction partition divided in the horizontal direction. The inner mirror surface of this lens faces the user (the user here refers to the reader of this article). An induction layer is designed on this inner mirror surface. Further, this induction layer is divided into two regions, namely the left and right regions. These two left and right regions are two induction partitions arranged in the horizontal direction. For example, the induction partition with a left position can be set as the first induction partition, and the induction partition with a right position can be set as the second induction partition. Among them, when the induction layer on the outer mirror surface of the glasses is partitioned, each formed induction partition can separately detect the self-capacitance value of the user's eyes during movement. Then, when the user's eyes move near the induction layer with partition design, the control command corresponding to the user's eye movement can be determined based on the change trend of the self-capacitance value of each different induction partition. Among them, the corresponding relationship between the control command and the eye movement has been pre-configured in the controller of the glasses. In this way, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's eye movement is. Thus, based on the pre-configured corresponding relationship between the control command and the eye movement, it can be known what the control command for controlling the controlled device corresponding to the user's current eye movement is.

[0077] Figure 7 Among them, (c) represents a lens with induction partition divided in a circular ring manner. The inner mirror surface of this lens faces the user (the user here refers to the reader of this article). An induction layer is designed on this inner mirror surface. Further, this induction layer is divided into two regions, namely the inner circle and the outer circular ring. These two regions are two induction partitions arranged in a circular ring pattern. For example, the induction partition at the position of the inner circle can be set as the first induction partition, and the induction partition at the position of the outer circular ring can be set as the second induction partition. Among them, when the induction layer on the inner mirror surface of the glasses is partitioned, each formed induction partition can separately detect the self-capacitance value of the user's eyes during movement. Then, when the user's eyes move near the induction layer with partition design, the control command corresponding to the user's eye movement can be determined based on the change trend of the self-capacitance value of each different induction partition. Among them, the corresponding relationship between the control command and the eye movement has been pre-configured in the controller of the glasses. In this way, after the controller detects the change trend of the self-capacitance value, based on this change trend of the self-capacitance value, it can correspond to what the user's eye movement is. Thus, based on the pre-configured corresponding relationship between the control command and the eye movement, it can be known what the control command for controlling the controlled device corresponding to the user's current eye movement is.

[0078] In some embodiments of the present application, the sensing layer includes at least two sensing sub-regions arranged in the vertical direction; the controller is specifically configured to: determine the closing rate of the inner mirror surface according to the self-capacitance change rates of the first self-capacitance value and the second self-capacitance value detected by the first sensing sub-region and the second sensing sub-region respectively; wherein, the first sensing sub-region and the second sensing sub-region are located on the same lens; if it is determined that the closing rate meets the set requirements, then determine that the control instruction is the control instruction corresponding to the effective blinking eye movement.

[0079] For example, based on Figure 7 the shown lens, assume the sensing sub-region at the upper position is the first sensing sub-region, and the sensing sub-region at the lower position is the second sensing sub-region. When the user wears glasses with the Figure 7 shown lens, when the eye corresponding to the lens performs a closing action, during the closing process of the user's eyes, in order to prevent the controller from also recognizing some unconscious blinking behaviors or physiological blinking behaviors of the user (such as dust entering the eyes) as control instructions for controlling the controlled device, then the rate at which the user's eyelid sweeps from the first sensing sub-region to the second sensing sub-region can be detected, so as to determine whether the closing rate of the user's eyes meets the set requirements. This set requirement indicates that the user's blinking is an effective blinking for controlling the operation of the device. In this way, it can be accurately determined whether the user's blinking behavior is an effective behavior for controlling the controlled device or an ineffective blinking behavior.

[0080] In some embodiments of the present application, the controller is specifically configured to: determine the corresponding control instruction according to the number of effective blinks.

[0081] For example, blinking the left eye / right eye alone once can be set to page turning; blinking the left / right eye twice alone can be set to volume adjustment.

[0082] Furthermore, it can also be based on whether the user blinks both eyes simultaneously. For example, blinking both eyes can be set to pause, and according to whether the duration of the user's both eyes closing exceeds the set duration. For example, for both eyes closing for more than 3 seconds, it can be set to shut down. The present application will not give further examples of control instructions corresponding to other eye movements.

[0083] In some embodiments of the present application, a ground loop isolation layer is provided in the first connection region between different sensing sub-regions and the second connection region between the sensing layer and the isolation layer.

[0084] Such as Figure 8As shown in the figure, it is a schematic diagram of a lens provided by an embodiment of the present application. The lens has an induction layer designed on the inner mirror surface. More specifically, the induction layer on the inner mirror surface further includes upper and lower induction zones, where the upper and lower induction zones are marked with a darker shade of gray. For the connection area between the upper and lower induction zones (i.e., the first connection area) and the splicing area between the induction layer and the isolation layer on the outer mirror surface (i.e., the second connection area), a loop ground isolation layer is designed, and the loop ground isolation layer has been marked with a lighter shade of gray. In this way, it can effectively reduce the interference of external factors on the induction layer when detecting the self-capacitance value, and improve the accuracy of the induction layer detection.

[0085] In some embodiments of the present application, the glasses further include a signal generator, and the signal generator is connected to the controller; the controller is specifically configured to: send a corresponding control signal to the signal generator according to the control instruction for the controlled device; the signal generator is used to receive the control signal, convert the control signal into an infrared electromagnetic signal and release it externally; the infrared electromagnetic signal is used to control the operation of the controlled device.

[0086] For example, the actual eye movement is judged by the difference in the self-capacitance value detected by the induction layer of the lens, and then the function required by the user is judged by the relationship between the preset eye state and the change of the self-capacitance value signal. The capacitance value signal is converted into an electrical signal corresponding to the function and sent to the controlled device through the signal generator. After receiving the corresponding signal, the controlled device will process and display it. The hand movement is the same as the eye movement, which will not be elaborated in the present application.
