[0035] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, the use of terms such as "first," "second," etc., in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are feasible to those skilled in the art. If a combination of technical solutions contradicts each other or cannot be implemented, it should be considered that such a combination does not exist and is not within the scope of protection claimed in this application. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0040] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are based on the directions shown in the figure and are only used to explain the relative positional relationship between the components in the posture shown in the figure. If the specific posture changes, the directional indication will also change accordingly.

[0041] In the field of smart glasses, the related technologies use mechanical rollers for adjustment. However, prolonged sliding can cause repeated friction between the soft tissue of the fingers and the hard grooves, leading to finger fatigue.

[0042] After careful research, the applicant discovered that in order to improve the accuracy of the roller operation feedback, existing designs generally set external teeth on the roller to create a gear-like concave-convex structure. When sliding for a long time, the fingers rub against the hard external teeth. At the same time, the mechanical roller structure has a button travel of 0.5mm to 1.2mm, and a single operation requires the application of 200mN to 500mN of pressing force, which can easily cause finger fatigue with high-frequency use.

[0043] The applicant considered using a capacitive touch solution, similar to the touchscreen principle of a mobile phone, to achieve touchscreen control functionality. However, the applicant found that applying the capacitive touch solution to smart glasses resulted in rather unresponsive control. Therefore, those skilled in the art initially believed that the touch solution was unsuitable for smart glasses.

[0044] After careful research, the applicant discovered two reasons for the low sensitivity of touch solutions applied to smart glasses: First, capacitive touch is sensitive to humid environments; sweat from fingers or the head while wearing the glasses may cause accidental touches or decreased sensitivity, while adding a waterproof design would significantly increase the complexity of the system. Second, due to the requirement for wearing comfort, the temples of the glasses need to be made of lightweight materials as much as possible. Currently, lightweight conductive materials such as carbon fiber and magnesium-aluminum alloys are widely used in temples, and capacitive touch solutions cannot penetrate the conductive shell to achieve touch response.

[0045] Therefore, this application proposes a smart glasses.

[0046] Reference Figures 1 to 3According to some embodiments of this application, this application provides a smart glasses 100, including a frame 1, an optical engine 8, a rolling element 6, and temples 3 mounted on opposite sides of the frame 1. A receiving cavity 31 is formed in the temple 3, and a circuit board 4, an integrated chip 5, an analog-to-digital converter, and an inductor coil 7 are disposed in the receiving cavity 31. The optical engine 8 is signal-connected to the integrated chip 5, the integrated chip 5 is mounted on the circuit board 4, the rolling element 6 is connected to the analog-to-digital converter, and the inductor coil 7 and the analog-to-digital converter are respectively signal-connected to the integrated chip 5. The temple 3 is provided with an opening communicating with the receiving cavity 31, and the rolling element 6 extends out of the opening from the receiving cavity 31.

[0047] The smart glasses 100 can be AR glasses or VR glasses (full Chinese name: Virtual Reality Glasses). The frame 1 has through holes for mounting lenses 2, typically two holes for mounting the left and right lenses 2. There are also two temples 3, one for each side. An optical engine 8 generates an image that is transmitted onto the lenses 2; there can also be two optical engines 8, mounted on the frame 1. The circuit board 4 can be a flexible circuit board with circuit layers. Electronic components mounted on the circuit board 4 can be directly or indirectly electrically connected to it. There are typically multiple inductors 7, but they can also be configured with multiple conductive layers. The integrated chip 5 can be an integrated circuit with touch functionality. The inductors 7 act as transmitters and receivers of an electric field. When a human body approaches the inductor 7, due to the capacitive nature of the human body, a coupling effect occurs between the human body and the electric field of the inductor 7. The human body's presence alters the electric field distribution on the inductor 7, causing a change in the electric field. This change typically manifests as a change in signal amplitude or phase, which is received by the integrated chip 5, enabling the determination of the touch location, pressure, time, and number of touches. An oscillator can also be included, its primary function being to generate a stable high-frequency AC signal. This signal is fed into the inductor coil 7 to create an electric field. Thus, when a hand approaches the inductor coil 7 from the outside 35 of the temple 3, the electric field of the inductor coil 7 changes. These changing signals are processed by the integrated chip 5, which can then recognize the user's touch or proximity. Simultaneously, the smart glasses 100 also includes a scroll bar 6, which rotates with the sliding of a finger. An analog-to-digital converter converts the number of rotations of the scroll bar 6 into an analog signal, which is then transmitted to the integrated chip 5. In practical applications, menu-related actions can be performed by sliding the scroll wheel 61. Because press-related actions are completed using inductive touch control, the pressure exerted on the scroll wheel 61 by the finger is reduced, preventing finger injuries during prolonged use. Specifically, the temple 3 is made of lightweight magnesium-aluminum alloy or carbon fiber; that is, the temple 3 is a magnesium-aluminum alloy temple or a carbon fiber temple.

[0048] The applicant should also explain that this invention, by using a roller 61 in conjunction with an inductive touch solution, solves the mutual exclusion problem between capacitive touch and lightweight conductive materials while reducing physical contact damage to the fingers caused by pressing the mechanical roller 61. Furthermore, the inductive touch solution employs a high-frequency oscillating coil matrix, achieving touch signal coupling through the eddy current effect of the conductive material. This breakthrough supports precise touch control under an all-metal / carbon fiber shell, while avoiding hand pressure from prolonged pressing of the roller 61. The roller 61 design, on the other hand, ensures accurate feedback for sliding operations while avoiding the limitations of traditional capacitive touch solutions applied to metal / carbon fiber shells; the two complement each other.

[0049] Reference Figures 1 to 3 In some embodiments, there are two temples 3. The side of the two temples 3 facing each other is defined as the inner side 34, and the side of one temple 3 away from the other temple 3 is defined as the outer side 35. The inductor coil 7 and the rolling element 6 are respectively disposed on opposite sides of the circuit board 4, and the inductor coil 7 is disposed close to the outer side 35.

[0050] The two temples 3 are the left temple and the right temple, respectively. The side of the left temple facing the right temple is the inner side 34, and the side of the left temple away from the right temple is the outer side 35. Similarly, the side of the right temple facing the left temple is the inner side 34, and the side of the right temple away from the left temple is the outer side 35. A scroll member 6 is connected to an analog-to-digital converter. To reduce electromagnetic interference between the scroll member 6, the analog-to-digital converter, and the inductor coil 7, the scroll member 6 and the analog-to-digital converter can be placed on one side of the circuit board 4, and the inductor coil 7 can be placed on the other side of the circuit board 4. Furthermore, for convenient touch operation, the inductor coil 7 can be placed on the outer side 35 of the temple 3, because the space on the inner side 34 is occupied by the user's head during actual use, and it is more convenient for the user to touch the corresponding position of the inductor coil 7 from the outer side 35 of the temple 3.

[0051] Reference Figure 1 and Figure 3 In some embodiments, a touch area 36 is provided on the outer side 35, the touch area 36 is provided corresponding to the inductor coil 7, and the touch area 36 protrudes from the outer side 35.

[0052] The touch area 36 corresponds to the inductor coil 7, which makes the electric field at the touch area 36 stronger and improves the detection sensitivity. The temple 3 may include a shell with a receiving cavity 31. The touch area 36 is part of the outer side 35. The shell of the touch area 36 protrudes to the side away from the receiving cavity 31 to form a protrusion. Since it is difficult for the human eye to see the touch area 36 on the temple 3 after wearing glasses, the protrusion of the touch area 36 makes it easier for the human hand to blindly identify the touch area 36 and improves the convenience of operation.

[0053] Reference Figure 4 and Figure 5 In some embodiments, a shielding element 9 is also provided inside the temple 3. An annular first groove 32 is provided on the inner wall 311 of the receiving cavity 31 near the outer side 35. One side of the annular shielding element 9 is installed in the first groove 32, and the inductor coil 7 is disposed within the annular shielding element 9. The annular shielding element 9 is spaced apart from the circuit board 4. The shielding element 9 can be a cylindrical or cuboid sidewall. It can be made of a thicker material; the thicker the shielding element 9, the better the shielding effectiveness. The shielding element 9 can also be made of conductive materials, such as copper, aluminum, or metallized plastic. These materials can effectively shield electromagnetic waves and reduce interference from external electromagnetic fields to the internal induction circuit. The shielding element 9 can be glued to the first groove 32.

[0054] Reference Figure 4 and Figure 5 In some embodiments, a second groove 33 is provided on the side of the inner wall 311 of the receiving cavity near the outer side 35. The second groove 33 is located within the first groove 32, and the inductor coil 7 is embedded in the second groove 33. Embedding the inductor coil 7 on the inner wall 311 of the receiving cavity is actually embedding it within the outer shell of the temple 3. This allows it to be closer to the outer side 35 of the temple 3, resulting in higher detection sensitivity when a person touches the outer shell of the temple 3 near the inductor coil 7.

[0055] Reference Figure 2 and Figure 3 In some embodiments, the rolling element 6 includes a roller 61 with external teeth 611 on its outer edge. A portion of the roller 61 extends outward from the opening, and an analog-to-digital converter (ADC) is used to record the number of rotations of the roller 61. The rolling element 6 can actually be a roller 61 with external teeth 611 on its outer edge, with a portion of the roller 61 extending outward from the opening to facilitate hand-rolling. The ADC can identify the number of rotations of the roller 61 and convert it into an analog signal, which is then sent to the integrated chip 5.

[0056] In some embodiments, the smart glasses 100 further includes a voice recognition module, which is signal-connected to the integrated chip 5. The voice recognition module receives voice commands from the user and sends them to the integrated chip 5. The voice recognition module, connected to the integrated chip 5, can receive user commands and convert them into electrical signals, which are then sent to the integrated chip 5 for corresponding processing. For example, a voice command could be to turn the glasses on or off, disable the touch function, or adjust the scroll bar 6.

[0057] Reference Figure 6 , Figure 6 This is a flowchart illustrating the control method for smart glasses according to the first embodiment of this application. This application provides a control method for smart glasses, applied to the aforementioned smart glasses 100. The steps of the control method for smart glasses include:

[0058] S100: When a finger is brought within a preset distance of the touch area 36, ​​the inductor coil 7 and the scroll wheel 61 are activated.

[0059] When a finger approaches the inductor coil 7, due to the capacitance of the human body, it couples with the electric field of the inductor coil 7. The human's presence alters the electric field distribution on the electrodes, causing a change in the electric field. This change typically manifests as a change in signal amplitude or phase, which is detected by the integrated chip 5, allowing the determination of the touch's location, pressure, duration, and frequency. Alternatively, an oscillator can be incorporated, its primary function being to generate a stable high-frequency AC signal. This signal is fed into the inductor coil 7 to create an electric field. Thus, when a hand approaches the inductor coil 7 from the outside 35 of the temple 3, the electric field of the inductor coil 7 changes. These changes are processed by the integrated chip 5, enabling the recognition of the user's touch or proximity. The inductor coil 7 and the scroll wheel 61 can be activated simultaneously when a finger approaches the touch area 36 of the temple 3; a preset distance of 3mm is possible. In the inactive state, the smart glasses 100 consumes less power. When in the active state, the integrated chip 5 and the inductor coil 7 consume more power. Setting an activation program can reduce the power consumption of the smart glasses 100, and at the same time, the power consumption is reduced by 60% compared with the normally open capacitive touch.

[0060] S200: Select an application from the displayed menu interface by scrolling the scroll wheel 61, or enter the selected application by clicking the touch area 36.

[0061] After turning on the optical engine 8, you will see the image emitted by the optical engine 8 on the lens 2, just like the image you can see on a TV or computer screen. You can select an application by scrolling the scroll wheel 61 in the displayed menu interface, just like scrolling the mouse to move the mouse to different application positions. After selecting an application, you can enter the selected application by clicking the touch area 36, ​​just like pressing the mouse's OK button to open the corresponding application.

[0062] In the above embodiments of this application, the relevant actions within the menu are performed by sliding the scroll wheel 61, and because the pressing actions are completed by inductive touch, the pressing operation of the scroll wheel 61 by the finger is reduced, so that the user will not suffer related damage to the finger during long-term operation.

[0063] Reference Figure 7 , Figure 7 This is a flowchart illustrating the control method for smart glasses according to the first embodiment of this application. It defines pressing the touch area 36 for less than a first preset time as a short press and pressing the touch area 36 for more than a second preset time as a long press. After the step of entering the selected application by clicking the touch area 36, ​​the method further includes the following steps:

[0064] S300: When it is detected that after a user enters the application, the scroll wheel 61 is operated for more than a third preset time, the short press function of the touch area 36 is turned off, while the long press function of the touch area 36 is retained.

[0065] In a specific embodiment, the first preset time can be 0.5 seconds, and the second preset time can be 1 second. The duration of the press is defined as a short press or a long press, and short presses and long presses are different input commands ultimately received by the integrated chip 5. When a user enters an application, if they only operate the scroll wheel 61 without touching the touch area 36 for more than a third preset time, the corresponding application scenario might be that the user is browsing a webpage or watching a video. In this case, the user does not want to click the "confirm" button to continue entering a certain application. At this time, the short press function can be turned off. The short press function corresponds to "confirm" entering a certain application, while the long press function exits the current mode. In this way, it can not only avoid the user accidentally touching the touch area 36 while browsing the webpage, causing misoperation, but also keep the inductor coil 7 or integrated chip 5 corresponding to the touch function in a low-power state, thus saving energy. Specifically, the third preset time can be 5 seconds.

[0066] In some embodiments, the steps of the smart glasses control method further include:

[0067] In step S400, the touch area 36 is pressed for more than a fourth preset time, while the scroll wheel 61 is scrolled to trigger the parameter adjustment function, the parameters of which include at least one of brightness or volume.

[0068] The fourth preset time can be 6 seconds. At this time, the image emitted by the optical engine 8 will be triggered and enter the adjustment interface. The adjustment interface allows you to select volume adjustment or brightness adjustment. You can then use the scroll wheel 61 to increase or decrease the volume or brightness. In this way, you can easily adjust the volume or brightness of the smart glasses 100.

[0069] In some embodiments, the number of touch areas 36 is two, with one touch area 36 corresponding to each temple 3. The control method for smart glasses further includes the following steps:

[0070] Step S500: Tap one of the touch areas 36 twice in succession to disable the function of the touch area 36; wherein the time interval between two consecutive taps is less than a fifth preset time.

[0071] The touch area 36 can be either the left temple or the right temple. When tapped twice consecutively, the integrated chip 5 can detect the tap signal and disable the function of the touch area 36. The time interval is designed to be less than a fifth preset time, mainly used to determine whether the tapping is continuous. For example, the fifth preset time can be 0.2 seconds. If the time interval between two taps is less than 0.2 seconds, it is determined to be a continuous tap, and the integrated chip 5 detects the instruction of two consecutive taps and disables the touch function of the touch area 36.

[0072] If one of the touch areas 36 is tapped three times consecutively, and the time interval between two taps is less than a fifth preset time, the scroll wheel 61 will be disabled. The integrated chip 5 detects the instruction of three consecutive taps and controls the scroll wheel 61 to be disabled. At this time, scrolling the scroll wheel 61 will not cause any adjustment to the menu bar.

[0073] If you tap another touch area 36 twice in succession, the functions of touch area 36 and scroll wheel 61 will be turned off simultaneously.

[0074] The other touch area 36 here can be the touch area 36 of the left temple. Therefore, the right temple touch area 36 is usually adjusted with the right finger. Since the right temple 3 is not frequently used, in order to avoid accidental closing, the touch area 36 of the left temple 3 can be set to close the operation by pressing the finger twice in succession. At the same time, the function of the touch area 36 and the scroll wheel 61 will be turned off.

[0075] The above description is merely an optional embodiment of this application and does not limit the scope of protection of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of this application.
