[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and apparatus known to those skilled in the art in the relevant field may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] This embodiment provides a nose pad for smart glasses. Smart glasses refer to wearable eyewear devices that have their own operating system, similar to smart terminals, and can achieve various functions through software installation. For example, smart glasses can be any of the following: virtual reality (VR) glasses, augmented reality (AR) glasses, or mixed reality (MR) glasses.

[0032] VR glasses, by wearing a helmet or glasses, completely isolate users from the real world and allow them to enter a completely new virtual world. VR glasses are suitable for scenarios that require an immersive experience, such as virtual tourism, virtual reality games, and virtual reality training.

[0033] AR glasses add virtual elements to the real world, such as overlaying virtual 3D objects, text, and images onto the screen of a mobile phone or tablet, or through devices like AR glasses. AR glasses can be applied in fields such as gaming, education, commerce, and healthcare.

[0034] MR glasses allow for switching and interaction between the real and virtual worlds. They can add virtual elements to real-world scenes, creating a more seamless blend between the virtual and real worlds. MR glasses are achieved through a combination of AR and VR technologies and can be applied in fields such as industry, architecture, and entertainment.

[0035] like Figure 1As shown, the nose pad 10 of the smart glasses may include a nose pad 11 and a Hall sensor 12. The Hall sensor 12 is enclosed in the nose pad 11. The nose pad 11 is provided with magnetized magnetic powder. The magnetic powder causes the nose pad 11 to change the magnetic field at the location of the Hall sensor 12 when it is subjected to pressure.

[0036] This embodiment allows for the determination of whether the nose pad is subjected to contact force applied by the user's nose bridge based on the magnetic field strength detected by the Hall sensor, thereby enabling wear detection of smart glasses.

[0037] In this embodiment, the nose pad 11 is flexible and can deform when it comes into contact with the bridge of the nose of a user wearing smart glasses. After the nose pad 11 deforms, the magnetic field of the magnetic powder inside the nose pad 11 at the location of the Hall sensor 12 also changes.

[0038] Specifically, when the contact position between the user's nose bridge and the nose pad 11 is different, or when the contact force is different, the magnetic field of the magnetic powder inside the nose pad 11 at the location of the Hall sensor 12 will also change differently.

[0039] Through this embodiment, the contact position between the user's nose bridge and the nose pad, and the contact force applied by the user's nose bridge to the nose pad can be determined based on the magnetic field strength detected by the Hall sensor, and then the interaction with the user can be carried out based on the contact position and / or contact force.

[0040] A Hall sensor is a transducer that converts a changing magnetic field into a change in output voltage. Hall sensors are primarily used for measuring magnetic fields, but they can also measure physical quantities that generate and influence magnetic fields. Examples include proximity switches, Hall effect sensors, position measurement devices, speed measurement devices, and current measurement devices.

[0041] Furthermore, the Hall sensor can output a voltage signal representing the magnetic field strength at its location.

[0042] In this embodiment, the smart glasses can determine the contact position and / or contact force between the user's nose bridge and the nose pad based on the magnetic field strength detected by the Hall sensor, and interact with the user based on the determined contact position and / or contact force.

[0043] The nose pads of the embodiments of this disclosure can provide a basis for new ways of interaction between users and smart glasses.

[0044] In one embodiment of this disclosure, as follows Figure 2 and Figure 3 As shown, the nose pad may also include a nose pad bracket 13, which is used to fix the nose pad to the body of the smart glasses, and the nose pad pad 11 is fixed on the nose pad bracket 13.

[0045] The main body of the smart glasses can be any part of the smart glasses except for the nose pads.

[0046] In this embodiment, the nose pad is connected and fixed to the main body of the smart glasses through a nose pad bracket, which allows the bridge of the nose to contact the nose pad when the user wears the smart glasses, improving the user's comfort when wearing the smart glasses, and also providing a basis for new interaction methods between the user and the smart glasses.

[0047] Furthermore, such as Figure 2 and Figure 3 As shown, the nose pad 11 is fixed to the nose support 13 by screws 15.

[0048] In this embodiment, the nose pad 11 and the nose support 13 are fixed together by screws, which makes it easy to replace the nose pad of the smart glasses.

[0049] In one embodiment of this disclosure, the nose pad 10 further includes a connecting wire 14 for connecting the Hall sensor to the circuit board in the body of the smart glasses. The nose pad support 13 may be a hollow structure, so that the connecting wire 14 passes through the nose pad support 13 and is connected to the Hall sensor and the circuit board in the body of the smart glasses, respectively.

[0050] This avoids exposed wiring, improving the safety and aesthetics of smart glasses.

[0051] In one embodiment of this disclosure, the magnetization intensity of the magnetic powder at different locations within the nose pad 11 is different.

[0052] Magnetization is a physical quantity that describes the strength of a macroscopic magnetic body. It is a vector field that represents the permanent or induced dipole magnetic moment of a magnetic material.

[0053] In this embodiment, magnetic fields of different strengths can be applied to the magnetic powder at different locations within the nose pad 11 to magnetize it, resulting in different magnetization intensities of the magnetic powder at different locations.

[0054] Furthermore, the magnetization intensity of the magnetic powder at different locations within the nose pad 11 varies. This means that the magnetic field at the location of the Hall sensor 12 changes more significantly when the contact position or contact force between the user's nose bridge and the nose pad 11 is different. This allows the smart glasses to more accurately determine the user's gestures and the wearing status of the smart glasses based on the magnetic field strength detected by the Hall sensor 12, thereby enabling more precise interaction with the user.

[0055] In one embodiment of this disclosure, the nose pad 11 is made of silicone. This improves the wearing comfort of the smart glasses.

[0056] In another embodiment of this disclosure, the nose pad 11 may also be made of sheet material, plastic, etc.

[0057] This disclosure also provides a smart glasses that may include the nose pad 10 described in any of the foregoing embodiments.

[0058] In one embodiment of this disclosure, such as Figure 4 As shown, the smart glasses 20 also includes a first control module 21, which is used to determine the gesture performed by the user on the smart glasses based on the magnetic field strength detected by the Hall sensor 12, and control the smart glasses to perform the operation corresponding to the gesture.

[0059] In this embodiment, at least one valid gesture and a corresponding operation for each valid gesture can be pre-set according to the application scenario or specific needs. For example, valid gestures may include pressing, long pressing, double pressing, lifting, double lifting, etc. Operations corresponding to valid gestures may include playing, pausing, increasing volume, decreasing volume, switching audio / video, etc. Operations corresponding to invalid gestures (i.e., other gestures that are not valid gestures) may be left unprocessed.

[0060] Furthermore, the normal contact force range between the user's nose bridge and the nose pad can be determined in advance based on the weight of the smart glasses during normal wear. If the first control module 21 determines, based on the magnetic field strength detected by the Hall sensor 12, that the contact force between the user's nose bridge and the nose pad is greater than this normal contact force range, then the user is determined to be pressing the smart glasses; if the first control module 21 determines, based on the magnetic field strength detected by the Hall sensor 12, that the contact force between the user's nose bridge and the nose pad is less than this normal contact force range, then the user is determined to be lifting the smart glasses.

[0061] Furthermore, the first control module 21 can determine the gesture performed by the user on the smart glasses. If the gesture is determined to be valid, the smart glasses are controlled to perform the operation corresponding to the valid gesture. If the gesture is determined to be invalid, the smart glasses are controlled not to respond to the invalid gesture and not to perform any processing.

[0062] In this embodiment, the smart glasses can determine the contact force between the user's nose bridge and the nose pad based on the Hall sensor 12, thereby determining the gesture performed by the user on the smart glasses, and then controlling the smart glasses to perform the operation corresponding to the gesture performed by the user on the smart glasses. This allows the user to interact with the smart glasses by changing the contact force between the nose bridge and the nose pad, which can increase the interaction scenarios of the smart glasses and improve the user experience.

[0063] In one embodiment of this disclosure, such as Figure 4As shown, the smart glasses 20 also includes a second control module 22, which is used to detect the wearing status of the smart glasses based on the magnetic field strength detected by the Hall sensor 12.

[0064] In one embodiment, a first contact force threshold for distinguishing between when the smart glasses are worn and when not worn can be pre-determined based on the weight of the smart glasses. If the second control module 22 determines, based on the magnetic field strength detected by the Hall sensor 12, that the contact force between the user's nose bridge and the nose pad is less than the first contact force threshold, then the smart glasses are determined to be worn as not worn; if the second control module 22 determines, based on the magnetic field strength detected by the Hall sensor 12, that the contact force between the user's nose bridge and the nose pad is greater than or equal to the first contact force threshold, then the smart glasses are determined to be worn.

[0065] Furthermore, the second control module 22 can control the smart glasses to enter a low-power mode when it detects that the smart glasses are not being worn, and control them to enter a normal working mode when it detects that they are being worn. The power consumption of the smart glasses in low-power mode is lower than that in normal working mode. This reduces the power consumption of the smart glasses and extends their usage time.

[0066] In another embodiment, a second contact force threshold for distinguishing between normal wear and detachment of the smart glasses can be pre-determined based on the weight of the smart glasses. If the second control module determines, based on the magnetic field strength detected by the Hall sensor, that the contact force between the user's nose bridge and the nose pad is greater than or equal to the second contact force threshold, then normal wear of the smart glasses can be determined. If the second control module determines, based on the magnetic field strength detected by the Hall sensor, that the contact force between the user's nose bridge and the nose pad is less than the second contact force threshold but greater than or equal to the first contact force threshold, then detachment of the smart glasses can be determined. The second contact force threshold is greater than the first contact force threshold.

[0067] Furthermore, the second control module can control the smart glasses to issue an alarm when it is detected that the smart glasses have fallen off, so as to remind the user and improve the safety of the user when using the smart glasses.

[0068] In one embodiment of this disclosure, the first control module 21 and the second control module 22 may be implemented by the same hardware or by different hardware, and no limitation is made herein.

[0069] This embodiment also provides a method for preparing a nose pad for smart glasses, such as... Figure 5As shown, it may include the following steps S5001 to S5003:

[0070] Step S5001: Add the liquid medium and magnetic powder into the set mold and stir evenly.

[0071] Stirring allows the magnetic powder to be evenly distributed in the stirred liquid medium.

[0072] In this embodiment, the liquid medium can be a curable medium, for example, the liquid medium can be liquid silicone.

[0073] Step S5002: Place the Hall sensor in the stirred liquid medium and solidify the stirred liquid medium to obtain the nose pad.

[0074] Before solidifying the stirred liquid medium, the Hall sensor is placed in the stirred liquid medium, so that the Hall sensor is covered in the solidified liquid medium, resulting in a nose pad covered with the Hall sensor.

[0075] In this embodiment, the stirred liquid medium may be vulcanized to solidify it; or the stirred liquid medium may be left to stand for a set time to solidify it.

[0076] Step S5003: Magnetize the magnetic powder in the nose pad.

[0077] In this embodiment, the magnetic powder in the nose pad can be magnetized by applying a specified magnetic field through an external device. For nose pads of the same model of smart glasses, the same magnetic field can be applied to magnetize the magnetic powder in the nose pad.

[0078] In one embodiment, different magnetic fields may be applied to the magnetic powder at different locations within the nose pad to achieve different magnetization intensities of the magnetic powder at different locations within the nose pad.

[0079] Furthermore, the magnetization intensity of the magnetic powder in different locations within the nose pad varies. This means that the magnetic field at the location of the Hall sensor changes more significantly depending on the contact position or contact force between the user's nose bridge and the nose pad. This allows the smart glasses to more accurately determine the user's gestures and the wearing status of the smart glasses based on the magnetic field strength detected by the Hall sensor, thereby enabling more precise interaction with the user.

[0080] After completing steps S5001 to S5003, the connecting wire for the Hall sensor can be passed through the nose pad bracket and connected to the circuit board of the smart glasses body. Then, the nose pad is fixed to the nose pad bracket with screws, thus completing the assembly of the nose pad and the smart glasses body.
