Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to a neckband-style wearable computer and its usage method. Background Technology

[0002] In today's world, the two major computing platforms—PCs, which have been the main source of technology and productivity computing for over 40 years, and smartphones, which have been the main source of entertainment services for 18 years—are now showing signs of reaching their limits in terms of innovation and development. A next-generation computing platform that is stronger than either of them is on the horizon.

[0003] The current mainstream consensus in the industry is that next-generation computing platforms rely on Augmented Reality (AR) technology. This technology overlays transparent, brighter images onto objects within the real-world field of view in AR glasses, enhancing perception of those objects. A drawback of this AR technology is that it acquires only a relatively specific range of augmented cognitive information, which is why, even after 20 years, it has only been geared towards B2B (business-to-business) rather than B2C (business-to-consumer). The industry should expand its development and innovation to include overlaying transparent and opaque images, brighter or darker than the overlaid objects, or images with alternating light and dark areas, onto objects within the real-world field of view in smart glasses, enhancing perception of those objects or anything outside the user's field of view that they want to know about. This expanded range of information would be more universal, accessible to the general public, and capable of B2C augmented cognitive information. The vast majority of the information provided by the two major computing platforms today is precisely this type of opaque, augmented cognitive image information that users want immediately, but which is mostly outside their immediate field of vision.

[0004] Currently, the two major computing platforms have a wide user base and a vast application ecosystem. However, while PCs are capable of technological productivity computing, they lack mobility and entertainment services. Smartphones, on the other hand, are primarily for entertainment, offering only portability. Mobile use is insecure, with small screens, poor battery life, and no technological productivity computing capabilities; users must take them out of their bags and hold them with their heads down. The functions of these two platforms are mutually exclusive. To become the next-generation computing platform, it must be far more powerful than the current two platforms in all aspects, overcoming their aforementioned shortcomings. Therefore, it is necessary to overcome the key technological gaps in mobile human-computer interaction, including command input and output display. Furthermore, it is crucial to design and develop mobile wearable computing devices with excellent industrial design solutions based on the current state of basic materials and components, and to incorporate various mature high-tech advancements. Currently, to promote the upgrading of computing platforms, the following practical technical challenges should be prioritized:

[0005] To overcome the limitations of PCs, their application in the mobile wearable field is necessary. This requires innovative technology to overlay, like a PC with an opaque back, real-world images, natural light and shadow, and any technological computing, entertainment, or other services needed by the public anytime, anywhere onto objects within the current AR glasses' real-world view. This technology must then be displayed and output on smart glasses that function as wearable computers. This necessitates solving the following key technologies and components that enable this breakthrough:

[0006] 1. Key technologies for mobile human-computer interaction command input: a mobile keyboard and mouse with PC-like computing capabilities and precise input, combined with smartphone-like touch input and superior voice human-computer interaction technology;

[0007] 2. One of the key technologies for output display in mobile human-machine delivery: innovative and expanded AR augmented reality information range smart glasses display technology, which can overlay transparent or opaque, brighter or darker, or alternating bright and dark images onto objects in the real field of view of smart glasses, to enhance the cognitive image information display technology of the objects (within the field of view) or any objects outside the field of view that the wearer wants to know; the existing Chinese patent application CN111077679A is one answer, but it still needs further improvement;

[0008] 3. The second key technology for output display in mobile human-machine delivery: Split-type smart glasses display technology. In this technology, the separate battery and smart glasses reduce the weight of the glasses, but the data cable connection between the battery and the main unit is cumbersome, and turning the head while wearing the glasses is affected by the pulling of the data cable. People hope for a smart glasses solution that combines the advantages of integrated smart glasses (no tangled wires, easy to put on and use) with the long battery life and output display requirements of split-type smart glasses. However, this technical problem, which has plagued the industry for many years, remains largely unsolved until the advent of new high-energy-density wearable batteries.

[0009] 4. An industrial design scheme that combines the functions of PCs and smartphones to create hybrid advantages and form a larger next-generation computing platform;

[0010] 5. Separate the operating systems, application software ecosystems, and computing power of PCs and smartphones into the cloud, and combine human-computer interaction input, control, and display output into mobile terminals;

[0011] The aforementioned technologies can give rise to EyePhonePC, a new personal terminal for mobile smart glasses and cloud computers. Its thin phone does not need to use low-nm high-end chips, has more powerful mobile cloud computing capabilities than PCs and smartphones, and can use various operating systems of desktop computers and smartphones without any modifications and inherit the huge traditional application software ecosystem resources of various operating systems. It has a more powerful ability to update and replace the current two major computing platforms in all aspects.

[0012] 6. The technology of PC computers used in fixed locations and mobile phones with small screens and poor battery life that are used for looking down into a technology that is attached to the front of your eyes, mouth and ears, and can be used anytime and anywhere, thus achieving a breakthrough in the scope of time and space; with the support of new mobile technologies such as 5G, big data, cloud computing, AGI and Lot, people will evolve into iSmarters who drive everything.

[0013] 7. The technology will comprehensively upgrade the two-dimensional display of PCs and smartphones to a mobile three-dimensional display, seamlessly connecting and overlaying the augmented reality (XR) mixed reality information technology seen and superimposed with the real three-dimensional world, enabling people to enter the three-dimensional Internet era from the two-dimensional Internet.

[0014] Therefore, a neck-mounted wearable computer and its usage method have become urgent problems to be solved. Summary of the Invention

[0015] In view of the problems mentioned above in the prior art, the present invention will provide a neck-mounted wearable computer and a method of using it.

[0016] To achieve the above objectives, the technical solution provided by the present invention is as follows: a neck-hanging wearable computer, comprising a palm keyboard device, neck-hanging smart glasses, a neck-hanging computer, and an automatic magnetic connection device.

[0017] The palm keyboard device consists of a left-hand keyboard and a right-hand keyboard, which are held in the palms of the left and right hands respectively, and their backs are attached to the palms by connecting fasteners; the keys of the left-hand keyboard and the right-hand keyboard are arranged in rows and columns, with no fewer than five rows and no fewer than five columns on each keyboard; the 26 letters of the English alphabet are arranged in three rows according to the QWERTY keyboard, in the second, third and fourth rows of the five rows, and are arranged sequentially on the left-hand keyboard and the right-hand keyboard;

[0018] The neck-hanging smart glasses can overlay at least rectangular video images of the same or different perspectives from both eyes, with variable size and position, and transparent or opaque backs, as PCs and smartphones, in the transparent real field of vision of the binocular glasses. The degree of transparency or opacity is modulated by an electrochromic lens layer disposed outside the optical lenses displaying the overlaid image.

[0019] The main unit of the neck-hanging computer and the neck-hanging battery with the neck-hanging cable can be used as a single unit or can be used separately:

[0020] The automatic magnetic connection device automatically connects the neck-hanging smart glasses to the neck-hanging computer's neck battery and / or host data transmission line, and the connection point of the magnetic connection device is located at the user's neck.

[0021] Furthermore, the row containing the letters QWERTYUIOP in the three rows of letters on the left and right keyboards is positioned closer to the wrist in the user's palm. The user can input mobile human-computer interaction commands by extending, bending, and stretching their fingers, with the fingertips lightly touching the keys, while simultaneously transmitting the commands wirelessly.

[0022] Furthermore, both the left-hand and right-hand keyboards include a key panel with a capacitive or resistive touchscreen, a PCB control board with a microprocessor, a keyboard battery, a keyboard shell, a connecting fastener for fixing the keyboard to the hand, a vibration motor for sending key touch feedback vibration signals, and a buzzer for sending key touch sound feedback signals. The connecting fastener is an elastic buckle or elastic band. The palm keyboard device is also equipped with a three-way selector switch for vibration, buzzer, or vibration-free silent operation. The key panel, vibration motor, buzzer, and selector switch are all communicatively coupled to the microprocessor on the PCB control board.

[0023] Furthermore, the handheld keyboard device is also equipped with a function switching button, which switches the keyboard input function of the keypad to either a skateboard mouse function or a writing pad function. When the keypad is switched to either the skateboard mouse function or the writing pad function, the left and right keyboards each activate one of the two different functions for simultaneous use. The handheld keyboard device is also equipped with mode indicator lights, which are communicatively coupled to the microprocessor on the PCB control board. The mode indicator lights include handwriting mode lights, keyboard mode lights, and mouse mode lights. The PCB control board is equipped with a wireless connection module unit capable of inputting human-computer interaction control commands to the neck-mounted computer host.

[0024] Furthermore, the smart glasses with a neckband are connected by a neckband cable between the two temples. An upper transmission line is hidden within the neckband cable. This upper transmission line is either a single bundle introduced into the neckband cable from one temple or two bundles introduced from both temples. It extends from the middle of the neckband cable and connects to an automatic magnetic connection device. The neckband computer is connected to the automatic magnetic connection device via a lower transmission line. The automatic magnetic connection device includes an upper magnetic connector and a lower magnetic connector. The upper magnetic connector is connected to the neckband cable via the upper transmission line. The lower transmission line, hidden within the neckband cable, extends to the back of the user's neck and connects to the lower magnetic connector. The lower magnetic connector has a guide block that ensures the lower magnetic connector always faces upwards and automatically attracts and guides the upper magnetic connector until they are correctly aligned and attracted to each other, thus establishing a communicative connection between the upper transmission line and the lower transmission line hidden within the neckband cable.

[0025] Furthermore, the lower magnetic connector is also provided with a fixing member, which fixes the lower magnetic connector to the collar or clothing at the back of the user's neck. The fixing member is an elastic clip, a buckle, or Velcro.

[0026] Furthermore, the outer surface of the battery of the neck computer is concealed with a magnetic charging transmitting coil for wireless charging of the neck computer host or other devices, as well as a port for charging or powering itself or other devices.

[0027] Furthermore, the neck-hook smart glasses are equipped with a bone conduction microphone for voice human-computer interaction and a piston-type air conduction headset;

[0028] The bone conduction microphone only picks up whispering sounds produced by the airflow rubbing against the respiratory tract when the user's vocal cords are not vibrating. The bone conduction microphone is fixed inside the nose pad of the smart glasses body. The temple of the smart glasses body is equipped with an electronic control unit with a microprocessor and video image display driver. The bone conduction microphone collects the amplitude-modulated audio electrical signal generated by the vibration of the nasal bone and then communicatively couples it to the microprocessor electronic control unit on the electronic control board.

[0029] The air conduction headset is located behind the two temples of the smart glasses, next to the user's ears, and is suspended inside the ear, directly facing the user's ear canal. The air conduction headset is equipped with a microphone touch sensor dual-selection switch, and the stem of the air conduction headset is movably connected to the smart glasses.

[0030] A method for using a neck-mounted wearable computer.

[0031] Step 1, Wearing Method:

[0032] First, hang the neck-hook computer around your neck, then place the neck-hook smart glasses on your ears and nose from head to head to complete the wearing process; the automatic magnetic connection device automatically connects and conducts the battery and / or data transmission line of the neck-hook computer host between the neck-hook smart glasses and the neck-hook computer.

[0033] Step 2, Operating Method:

[0034] The combination of the palm keyboard and the neck-mounted smart glasses allows users to interact with the neck-mounted computer in various postures, including standing, walking, sitting, and lying down. The specific operation method is as follows:

[0035] When interacting with the computer while walking, you can type by lightly touching the keyboard keys in your palm, or switch to the mouse interface to control the skateboard mouse by touching the function switch key, or switch to the writing board interface to write character instructions and input them into the neck computer host in a blind writing manner.

[0036] It should be noted that, due to the need for handheld operation and the inability to see the keys while walking, the keyboard of this invention must be operated by touch typing. The key layout of the KTI keyboard was chosen because it is the most widely used keyboard in the world, and many people are familiar with its operation and can touch type, which greatly reduces the time required to become familiar with or learn to touch type on this keyboard; when practicing operation for the first time, one can look at the virtual keyboard on the screen while typing.

[0037] Before using the traditional Koti keyboard for touch typing or the writing tablet for blind writing, users must use the skateboard mouse to shrink the display screen inside the neck-mounted smart glasses according to their walking speed and drag it to the bottom of the glasses' field of vision to ensure safe operation.

[0038] When in a noisy environment or when you need to make a private call or give a voice command, press the piston-type air conduction headset to isolate external noise. At the same time, touch the two-way switch on the headset to turn off the air conduction microphone and switch to the bone conduction microphone. With no vibration of the throat and vocal cords, the exhaled airflow rubs against the airway to produce whispered language command information to realize human-computer interaction input to the computer host.

[0039] After receiving input command information, the neck-hanging computer host uploads the audio and video information of the calculation results to the neck-hanging smart glasses, outputting human-computer interaction video and audio display for the user, thus completing human-computer interaction;

[0040] The neckband-style smart glasses provide users with human-computer interaction output through various audio and video display methods, including VR virtual reality display and widescreen movie display, where the back of the glasses is opaque and overlaid with virtual video images, covering the entire field of vision. In this case, the entire field of vision is fully covered by an opaque electrochromic lens layer. AR augmented reality display provides enhanced cognitive information by overlaying brighter virtual video images (brighter than the overlaid object) onto the transparent real-world field of vision, again covered by a fully transparent electrochromic lens layer. It also provides real-world images (brighter, darker, or alternating bright and dark) overlaid within or outside the glasses' field of vision. The display of any audio and video information, such as the back of the rectangular screen of a PC or smartphone, which is opaque and desired by the wearer, is achieved by covering the rectangular screen portion superimposed on the transparent real-world field of vision of the glasses with an opaque electrochromic lens layer. By changing the size of the PC screen display within the glasses' real-world field of vision, various video displays, such as those for outdoor giant screens, indoor wall-mounted TVs, laptops, and tablets, or the audio and video display of a lower horizontal banner for information needed while running, cycling, or driving, are provided. When the neck-mounted smart glasses superimpose rectangular video images from the same or different perspectives of both eyes within the real-world field of vision of the binocular glasses, the aforementioned video images are 2D or 3D displayed images.

[0041] Step 3: A method for combining smartphones with various operating systems and PCs with various operating systems via a mobile cloud computer terminal:

[0042] The host of the neck-mounted computer is a smartphone with any current closed or open operating system (e.g., closed iOS, open Android, or open Harmony OS). A smartphone can download and install multiple cloud phone apps and cloud computer apps with different operating systems. (For example, a Samsung Android phone can download and install cloud phone apps with operating systems such as Apple iOS, Alibaba YunOS, and Xiaomi Android; as well as cloud computer apps such as Microsoft Windows Azure, Huawei iCloud PC, Apple iCloud, and China Telecom's Tianyi Cloud.) It can also directly access all application software ecosystem resources in the world at any time on the cloud.

[0043] When using the mobile cloud computer terminal, the smartphone can input information by touching the keyboard keys in the palm of its hand, touching the mouse on the touchpad, writing on the writing board, or using ordinary voice or whispered voice input. The input information is then transmitted to the cloud computer for calculation via wireless communication with a peak transmission rate of 5G or higher, and the video image information of the calculation results is wirelessly received and projected onto the screen of the neck-hanging smart glasses for output and display.

[0044] The advantages of this invention compared to existing technologies are as follows: This invention achieves a mobile keyboard and mouse with the productivity and computational capabilities of a PC through a palm-sized keyboard, while also possessing the finger touch input of a smartphone; by combining a bone conduction microphone with a piston-type air conduction headset and integrating it with smart glasses, it achieves a superior voice human-computer interaction technology that allows for both everyday speech and whispers, while avoiding the drawbacks of traditional wireless headphones and microphones such as poor battery life and frequent removal for charging; utilizing the multi-functional display technology of split smart glasses and adopting a neckband structure, the entire battery unit is separated from the smart glasses, reducing the weight of the glasses and avoiding the pulling interference of long connecting wires on the temples.

[0045] Relying on the mobile human-computer interaction of inputting the neck-mounted computer host with a palm keyboard and outputting a multi-functional smart glasses display, and with the support of cloud computing, compared with existing PC computers and smartphones, the neck-mounted wearable computer of this invention is a new mobile cloud computer terminal that has all types of devices and their entire application ecosystem of the world's two major computing platforms, PC computers and smartphones.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0058] The following detailed description, in conjunction with the accompanying drawings, provides a neckband-style wearable computer and its usage method according to the present invention.

[0059] Combined with appendix Figure 1-9 This invention will be described in detail below.

[0060] A neck-mounted wearable computer includes a palm keyboard device 1, neck-mounted smart glasses 2, a neck-mounted computer 3, and an automatic magnetic connection device 4. The palm keyboard device 1 consists of a left-hand keyboard 5 and a right-hand keyboard 6, which are held in the palms of the left and right hands respectively. The back of the keyboard is attached to the palm by a connecting fastener 7. The keys 8 of the left-hand keyboard 5 and the right-hand keyboard 6 are arranged in rows and columns, with no less than five rows and no less than five columns on each keyboard. The 26 letters of the English alphabet on the keys 8 are arranged in three rows according to the QWERTY keyboard, in the second, third, and fourth rows of the five rows, and are arranged sequentially on the left-hand keyboard 5 and the right-hand keyboard 6, so that users can directly inherit or quickly learn the touch typing technique of traditional keyboards while ensuring safe use while walking.

[0061] The neck-hanging smart glasses 2 can overlay rectangular video images of the same or different perspectives from both eyes, with variable size and position, and transparent or opaque backs, as PCs and smartphones, in the transparent real field of vision of binocular glasses. The degree of transparency or opacity is modulated by an electrochromic lens layer set outside the optical lenses that display the overlaid image.

[0062] The main unit of the neck-hanging computer 3 and the neck-hanging battery 31 with the neck-hanging cable can be used as a whole or separately: the automatic magnetic connection device 4 automatically connects the neck-hanging smart glasses 2 to the neck-hanging battery 31 and / or the main unit data transmission line of the neck-hanging computer 3. The connection point of the automatic magnetic connection device 4 is set at the user's neck. The neck-hanging computer 3 can be decorated with a necklace, scarf, neckerchief, vest, suspender strap of suit pants, tie or other clothing accessories, so that the entire neck-hanging computer 3 is hidden in the wearable clothing accessory. The lower end of the clothing accessory is also attached with a magnetic piece or card to connect and position with the magnetic piece or buckle on the user's belt or waistband, so as to prevent the neck-hanging computer 3 from swinging from side to side when walking.

[0063] In one embodiment of this application, a Samsung S20 smartphone with DP projection function is selected as the neck-mounted computer host 3, which is attached to the magnetic charging transmitter coil 26 of the neck-mounted battery 31 for charging and use simultaneously; an XREAL AIR 2Pro model from Unicoon (Beijing) Co., Ltd. is selected, featuring an electroluminescent dimming layer with adjustable lens transparency. The dimming layer can be dimmed in multiple levels via a touch switch on the temple of the glasses, enabling the finished smart glasses 2 to overlay DP-connected projection, PC computer, and smartphone rectangular video images in the transparent real-world field of view of the binocular glasses for output display; in conjunction with the palm keyboard 1 for inputting control commands, mobile human-computer interaction is realized.

[0064] The selected finished smart glasses 2 originally had a speaker and a microphone component on the temple, which were respectively connected to the microprocessor control unit 30 on the temple. This embodiment also selected a common wired piston-type headset 29 with a two-way touch switch mounted on its surface, which was integrally connected to the temple of the glasses. A BM-06 bone conduction microphone 28 from Ningbo Shuozheng Electronics Co., Ltd., with a diameter of 8 mm and a height of 3.5 mm, was modified and hidden inside the nose pad of the glasses. The earpiece of the piston-type headset 29 directly and simply replaced the speaker component on the temple of the selected finished glasses 2, and was connected to the microprocessor control unit 30. The microphone component of the piston-type headset 29 and the BM-06 bone conduction microphone 28 were connected to the two-way touch switch to select one of them to replace the original microphone component on the temple of the finished glasses 2, and were connected to the microprocessor control unit 30 to implement human-computer interaction between normal voice whisper commands and whispered voice commands. (See...) Figure 1 A schematic diagram of the structure of the neckband-style wearable computer of the present invention, and Figure 9 (Electrical control schematic diagram of an embodiment.)

[0065] In this embodiment, the male connector of a commercially available DP-type magnetic adapter from Yishi Technology is selected as the lower magnetic connector 7, which is connected to the S20 smartphone host 3 via the lower transmission line 21. The female connector of the magnetic adapter is selected as the upper magnetic connector 22, which is connected to the XREAL AIR 2Pro smart glasses 2 via the upper transmission line 20, to form the automatic magnetic connection device 4 of the split smart glasses 2 (see...). Figure 9 (Electrical control schematic diagram of an embodiment).

[0066] In one embodiment of this application, the row containing the letters of QWERTYUIOP in the three rows of letters on the left keyboard 5 and the right keyboard 6 is arranged in the user's palm closer to the wrist. The user can lightly touch the key 8 with the fingertips of their fingers by extending, bending and stretching their fingers to complete the operation input of mobile human-computer interaction command information, and at the same time, the command information is wirelessly transmitted and output.

[0067] In one embodiment of this application, both the left-hand keyboard 5 and the right-hand keyboard 6 include a key panel 9 with a capacitive or resistive touchscreen, a PCB control board 10 with a microprocessor, a keyboard battery 11, a keyboard housing 12, a connecting fastener 7 for fixing the keyboard to the hand, a vibration motor 13 for sending touch feedback vibration signals from the keys 8, and a buzzer 14 for sending touch sound feedback signals from the keys 8. The connecting fastener 7 is an elastic buckle or elastic band. The palm keyboard device 1 is also provided with a three-way selector switch 15 for vibration, buzzing, or vibration-free silence. The key panel 9, the vibration motor 13, the buzzer 14, and the selector switch 15 are all communicatively coupled to the microprocessor of the PCB control board 10.

[0068] In one embodiment of this application, the palm keyboard device 1 is further provided with a function switching button 16, which switches the keyboard input function of the keypad 9 to either a skateboard mouse function or a writing pad function. When the keypad 9 is switched to either the skateboard mouse function or the writing pad function, the left keyboard 5 and the right keyboard 6 each activate one of the two different functions for simultaneous use. For example, when the mouse function of the right keyboard 6 is activated, the writing pad function of the left keyboard 5 is activated. After the right hand controls the mouse to position the mouse cursor on the screen of the neck-hanging smart glasses 2, the right index finger can be used to write on the writing pad of the left keyboard 5 to input control commands. The palm keyboard device 1 is also provided with a mode indicator light 17, which is communicatively coupled to the microprocessor of the PCB control board 10. The mode indicator light 17 includes a handwriting mode light, a keyboard mode light, and a mouse mode light. The PCB control board 10 is provided with a wireless connection module unit 18 that can input human-computer interaction control commands to the host of the neck-hanging computer 3.

[0069] In one embodiment of this application, a neckband smart glasses 2 has a neckband cable 19 connecting the two temples. An upper transmission line 20 is hidden within the neckband cable 19. The upper transmission line 20 is introduced into the neckband cable 19 in a single bundle from one temple or in two bundles from both temples (the dual-bundle introduction method makes the entire neckband cable thinner and more flexible). It extends from the middle of the neckband cable 19 to connect to an automatic magnetic connection device 4. The neckband computer 3 is connected to the automatic magnetic connection device via a lower transmission line 21. 4; The automatic magnetic connection device 4 includes an upper magnetic connector 22 and a lower magnetic connector 23. The upper magnetic connector 22 is connected to the eyeglasses neck strap 19 via an upper transmission line 20. The lower transmission line 21 extends to the back of the user's neck and connects to the lower magnetic connector 23. The lower magnetic connector 23 is provided with a guide block 24. The guide block 24 keeps the lower magnetic connector 23 facing upwards and simultaneously allows the upper magnetic connector 22 to be automatically attracted and guided by the lower magnetic connector 23 until they are correctly aligned and attracted to each other, connecting the upper transmission line 20 and the lower transmission line 21.

[0070] In one embodiment of this application, the lower magnetic connector 23 is further provided with a fixing member 25, which fixes the lower magnetic connector 23 to the collar or clothing at the back of the user's neck. The fixing member 25 is an elastic clip, elastic band or Velcro.

[0071] In one embodiment of this application, the neck computer 3 has a hollow neck bracket 32 ​​at the upper end of the neck battery 31 for easy wearing. The hollow bracket contains a portion of the neck battery 31 connected in parallel to balance the weight of the upper and lower ends. The outer surface of the neck battery 31 is provided with a magnetic charging transmitting coil 26 for wireless charging of the host of the neck computer or other devices, and a socket 27 for charging or powering itself or other devices.

[0072] In one embodiment of this application, the neck-mounted smart glasses 2 are equipped with a bone conduction microphone 28 for voice human-computer interaction and a piston-type air conduction headset 29. The bone conduction microphone 28 only picks up whispered sound information produced by the user's exhaled airflow rubbing against the respiratory tract when the user's vocal cords are not vibrating. The bone conduction microphone 28 is fixed inside the nose pad of the smart glasses body. The temples of the smart glasses body are equipped with a microprocessor control unit 30 with display driver. The bone conduction microphone 28 collects the amplitude-modulated audio electrical signal generated by the sound vibration of the nasal bone and then communicatively couples it to the microprocessor control unit 30 on the control board. The air conduction headset 29 is located at the part of the user's ears behind the two temples of the smart glasses body, and is suspended in the ear facing the user's ear vortex. It is equipped with a microphone touch-sensitive two-way switch. The stem of the air conduction headset 29 is movably connected to the smart glasses body.

[0073] The specific implementation process of the method for using a neck-mounted wearable computer according to the present invention is as follows:

[0075] First, hang the neck-hanging computer around your neck, then place the neck-hanging smart glasses 2 on your ears and nose from head to head to complete the wearing process; the automatic magnetic connection device 4 automatically connects and conducts the battery 31 and / or the data transmission line of the neck-hanging computer host between the neck-hanging smart glasses 2 and the neck-hanging computer 3.

[0076] Step 2, Operating Method:

[0077] The handheld keyboard device 1 and the neck-hanging smart glasses 2 are used together to enable users to interact with the neck-hanging wearable computer in standing, walking, sitting, or lying postures. The specific operation method is as follows:

[0078] When interacting with the computer while walking, you can type by lightly touching the keyboard key 8 in your palm, or switch to the mouse interface to control the skateboard mouse by touching the function switch key 16, or switch to the writing board interface to write character instructions and input them into the neck computer host in a blind writing manner.

[0079] Before using the traditional Koti keyboard for touch typing or the writing tablet for blind writing, users must use the skateboard mouse to shrink the display screen inside the neck-mounted smart glasses according to their walking speed, drag it to the bottom of the glasses' field of vision, and walk at a low speed to ensure safety.

[0080] When in a noisy environment or when you need to make a private call or give a voice command, press the piston-type air conduction headset 29 to isolate external noise. At the same time, touch the two-way switch on the headset to turn off the microphone of the air conduction headset 29 and switch to turn on the bone conduction microphone 28. With no vibration of the throat and vocal cords, exhale the airflow to rub against the airway and realize human-computer interaction input to the neck-mounted computer host in the form of whispered bone conduction language command information.

[0081] When there is no need for keyboard typing during human-computer interaction while standing, walking, sitting, or lying down, a simpler method can be used: select the touch screen mouse of a smartphone or computer host, or the existing ring mouse to directly control and achieve human-computer interaction input.

[0082] After receiving the input instruction information, the neck-hanging computer host uploads the audio and video information of the calculation result to the neck-hanging smart glasses 2, and outputs the human-computer interaction video and audio display for the user, thus completing the human-computer interaction;

[0083] The neckband smart glasses 2 provide users with human-computer interaction output through various audio and video display methods, including VR virtual reality display and widescreen movie display methods where virtual video images are superimposed and the entire back of the glasses' field of vision is opaque, in which case the entire field of vision is fully covered by an opaque electrochromic lens layer; AR augmented reality display (such as real-world AR navigation) where a brighter virtual video image than the superimposed object is superimposed on the transparent real field of vision, in which case the entire field of vision is covered by a fully transparent electrochromic lens layer; and real-world images, whether brighter or darker than the superimposed object or alternating bright and dark, are superimposed on the transparent real field of vision, either inside or outside the glasses' field of vision. This also includes methods for displaying information in the form of rectangular screens on existing PCs and smartphones—screens with opaque backs—that provide the most information that eyeglass wearers want to know, are most in demand, and are most universally relevant. In this case, the rectangular screen portion superimposed on the transparent real-world field of vision of the glasses is covered by an opaque electrochromic lens layer. Furthermore, it includes providing audio and video displays such as outdoor giant screens, indoor wall-mounted TVs, laptops, tablets, or lower horizontal banners displaying information needed for running, cycling, or driving by changing the size of the PC screen display within the real-world field of vision of the glasses. When the neckband smart glasses superimpose rectangular video images from the same or different perspectives of both eyes within the real-world field of vision of the binocular glasses, all of the aforementioned video images are 2D or 3D displayed images.

[0084] Step 3: The neck-mounted wearable computer also employs a method of using a combination of smartphones with multiple operating systems and PCs with multiple operating systems via a mobile cloud computer terminal.

[0085] The host of the neck-mounted computer 3 can be any physical smartphone with a closed or open operating system (such as a smartphone with iOS, Android, or HarmonyOS installed). A physical smartphone can integrate multiple cloud phone apps and cloud computer apps with different operating systems (such as installing existing Alibaba Cloud phone apps and Huawei Cloud phone apps, and then installing PC-type Alibaba Cloud computer apps, Huawei Cloud computer apps, and Microsoft Cloud computer apps). In this way, one device can have and use the functions of various smartphones and various PCs, and can download and use all their respective ecological resources from the cloud (for example, using Apple's closed iOS operating system iPhone 15 as the host, you can choose to download the open HarmonyOS operating system Huawei Kunpeng cloud phone app, and then you can choose to download Apple Mac OS iCloud cloud computer app and Alibaba Cloud Linux operating system Wuying cloud computer, etc., and you can use various application software on their cloud at any time. A single smartphone can have all the world's IT ecological resources).

[0086] The neck-mounted wearable computer, using a smartphone as its host, only needs to transmit information from finger touches on the palm keyboard (keyboard 8), touches on the skateboard mouse, or handwritten notes, as well as ordinary voice or whispered voice messages, via existing 5G or higher peak transmission rate wireless communication. This information is then sent with low latency to a cloud computer for computation, and the video image information of the computation results is wirelessly received and displayed on the screen of the neck-mounted smart glasses (2). Relying on powerful cloud computing, all commonly used PCs and smartphones can be integrated and compatible with their operating systems and massive application software without any modifications. This makes the neck-mounted wearable computer a new type of wearable mobile terminal cloud computer, a new generation of mobile space computing platform larger than the existing PC and smartphone computing platforms.

[0087] Because neck-worn wearable computers utilize powerful cloud computing, enabling a large amount of computation to be performed in cloud data centers, the smartphones used in neck-worn wearable computers can be equipped with thin phones using low-end chips manufactured with high-nanometer processes, avoiding the use of high-end chips manufactured with low-nanometer processes and resulting in lower costs.

[0088] The neck-hook smart glasses 2, a wearable computer, allows users to independently display audio and video images from different perspectives with both eyes. This enables users to see superimposed 3D stereoscopic video images within the glasses' field of vision. Thus, this device simultaneously introduces two of the largest computing platforms today—PCs (which have been used for stationary 2D displays for over 40 years) and smartphones (which have been used for portable 2D displays for over 10 years)—into the new fields of wearable computing and 3D stereoscopic display. This represents a technological breakthrough in both the mobile use and stereoscopic display of the two largest computing platforms today.

[0089] The PC cloud computer, using a neck-worn wearable computer, enables technological productivity computing to enter a wider outdoor mobile field, allowing for easy computation of various big-bit application plugins powered by big data and artificial intelligence anytime, anywhere. The cloud phone usage method of the computer host phone transforms the entertainment and services of smartphones from being portable in a bag to being mobile wearable, eliminating the need to hold the phone with your head down, and providing a large screen display and long battery life. This device combines the two major computing platforms of PC and smartphone into one, while simultaneously connecting to the Internet of Things (IoT) that connects everything for human use, and further enhanced by AGI (Artificial Intelligence of Things), making them readily available to people's eyes, ears, and mouths, enabling them to become networked intelligent beings and realizing the science fiction dream of iSmartor.

[0090] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
