Waist belt-type wearable computer and use method

Abstract

A waist belt-type wearable computer and a use method. Firstly, a waist belt-type computer is tied to the waist, then a fixing member provided on a guide block connected to a lower magnetic connector on the rear upper part of a waist belt is clamped on a collar or wearable object at the nape area of a user, and then neck-mounted smart glasses are mounted on the ears and the nose bridge in a downward manner, so that wearing is completed. The user interacts with the waist belt-type wearable computer while standing, walking, sitting, and lying down. A split-type smart glasses display technology and a waist belt-type structure are employed, to separate a battery and a system unit from the smart glasses, thereby reducing the weight of the glasses while avoiding pulling interference of a neck-hanging cable.

Description

A belt-type wearable computer and its use method Technical Field

[0001] The present invention relates to the technical field of intelligent wearable devices, and in particular to a belt-type wearable computer and a method of using the same. Background Art

[0002] In today's world, the two major computing platforms, PCs, which have been around for more than 40 years and are mainly used for technology and productivity computing, and smartphones, which have been around for 18 years and are mainly used for entertainment services, have now reached the ceiling of their innovative development, and a next-generation computing platform that is more powerful than both is about to emerge.

[0003] The next-generation computing platform currently being mainstreamed in the industry is augmented reality (AR). This technology superimposes transparent, brighter-than-the-superimposed imagery on objects within the real-world field of view of AR glasses, enhancing cognition of those objects. A drawback of this AR technology is that the information it captures is relatively specialized and niche, which is why, 20 years after its invention, it has been limited to businesses for business-to-business (B2B) use and not for the general public. The industry should expand its development and innovation to include overlaying transparent or opaque imagery on objects within the real-world field of view of smart glasses, brighter, darker, or alternating between bright and dark, to enhance cognition of the objects within the wearer's field of view, or any objects outside the wearer's field of view that the wearer desires to know about. This expanded scope of information is universal, accessible to the general public, and can be used for consumer-to-consumer (B2C) purposes. The majority of the public information currently provided by the two major computing platforms is precisely this type of opaque, back-of-the-envelope augmented cognition information that users need and often falls outside their immediate field of view.

[0004] Today, the two major computing platforms have a wide audience and a huge application ecosystem. However, PCs can be used for scientific and technological productivity computing but cannot be used for mobile and entertainment services. Smartphones can be used for entertainment services, but they are only portable and unsafe for mobile use. They have small screens, poor battery life, no scientific and technological productivity computing, and require you to reach for your wallet and hold your hands to use them. The functions of the two major platforms are mutually exclusive. To become the next generation computing platform, it must be more powerful than the two major computing platforms in all aspects and must overcome their above-mentioned shortcomings. Therefore, it is necessary to overcome the key shortcomings of command input and output display in mobile human-computer interaction. It is necessary to design and develop mobile wearable computer devices with excellent industrial design solutions based on the current status of basic materials and components, and to incorporate various mature high-tech technologies. At present, in order to promote the upgrading of computing platforms, we give priority to solving the following practical technical problems:

[0005] To overcome the shortcomings of PCs, they must be introduced into the mobile wearable field. Furthermore, innovative technologies must be developed to overlay real-world image information, similar to that of PCs, with natural light and dark variations, onto the objects in the real field of view of current AR glasses. This technology can display and output universal image information, such as any technology, computing, life, and entertainment services that the public needs anytime, anywhere, with an opaque back like that of a PC, on the objects in the real field of view of AR glasses. This technology requires the following breakthrough technologies and corresponding key technologies:

[0006] 1. Key technologies for command input in mobile human-computer interaction: a keyboard and mouse with the mobile, precise input capabilities of PCs, combined with the finger touch input of smartphones, and enhanced voice human-computer interaction technology;

[0007] 2. One of the key output display technologies for mobile human-machine delivery: Smart glasses display technology that innovatively expands the scope of AR (augmented reality) information. This technology can overlay transparent or opaque images on objects in the smart glasses' real field of view, making the overlaid objects brighter, darker, or alternating between bright and dark. This technology enhances cognition of objects within the smart glasses' field of view, as well as any objects outside the wearer's field of view that they desire to know. Prior art Chinese patent application CN111077679A is one answer, but further refinement is needed.

[0008] 3. The second key technology for output and display in mobile human-machine delivery: Split smart glasses. While split-type display technology, where the battery and host are separated from the smart glasses, reduces weight, the data cable connection between the battery and host is cumbersome, and movement while wearing the glasses can cause interference with the cable. People long for smart glasses that offer the same advantages as integrated smart glasses, with no wires and the convenience of simple, ready-to-wear functionality, while also meeting the long-lasting display and battery life requirements of split-type smart glasses. However, this technical challenge, which has plagued the industry for years, remains largely unresolved until the advent of new wearable batteries with high specific energy.

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

[0010] 5. Distribute PC and smartphone operating systems, application software ecosystems, and computing power to the cloud, while integrating human-computer interaction input, control, and display output into mobile terminals.

[0011] The aforementioned technologies can create a new mobile smart glasses-like cloud computer, the EyePhonePC. This thin phone, which doesn't require low-nm high-end chips, boasts more powerful mobile cloud computing capabilities than PCs and smartphones. It can also run various desktop and smartphone operating systems without modification, inheriting the vast ecosystem of traditional application software and possessing a more robust upgrade capability than the two major computing platforms today.

[0012] 6. The technology of PCs, used at fixed locations, and small, poorly powered mobile phones, which are often pulled out of pockets and used with low battery life, will be merged and evolved into a mobile device that can be used anytime, anywhere, and can be used anywhere. This technology will achieve a breakthrough in spatial and temporal dimensions. Combined with new technologies such as 5G, big data, cloud computing, artificial general intelligence (AGI), and the Internet of Things (IoT), people will evolve into intelligent networked beings (iSmarter), who drive everything.

[0013] 7. The technology comprehensively upgrades the two-dimensional flat display of PCs and smartphones to mobile three-dimensional stereoscopic display. What is seen and superimposed by augmented reality (XR) and mixed reality information technology are seamlessly connected and superimposed with the real three-dimensional world, allowing people to enter the three-dimensional Internet era from the two-dimensional Internet.

[0014] Therefore, a belt-type wearable computer and a method of using the same have become issues that need to be urgently addressed. Technical Solutions

[0015] In order to solve the above problems in the prior art, the present invention provides a belt-type wearable computer and a method of using the same.

[0016] To achieve the above objectives, the present invention provides a technical solution: a waistband-type wearable computer comprising a palm keyboard device, neck-hanging smart glasses, a waistband computer, and an automatic magnetic connection device. The palm keyboard device comprises a left-hand keyboard and a right-hand keyboard, each of which is held in the palm of the left hand and the right hand, respectively, with the backs of the left-hand and right-hand keyboards attached to the palms via a connecting fixture. The keys of the left-hand and right-hand keyboards are arranged in rows and columns, with each keyboard having at least five rows and at least five columns. The 26 English letters of the keys are arranged in three rows according to the QWERTY keyboard, arranged in the second, third, and fourth rows of the five rows, and arranged consecutively on the left-hand and right-hand keyboards.

[0017] The neck-hanging smart glasses can superimpose at least a rectangular binocular video image of the same or different viewing angles, with a transparent or opaque back, similar to PCs and smartphones, on the transparent real-world field of view of the binocular glasses. The degree of transparency or opacity is modulated by an electrochromic lens layer disposed outside the optical lens displaying the superimposed image.

[0018] The waistband computer includes a split waistband with an auxiliary power supply and a computer host that can be used separately or together;

[0019] The automatic magnetic connection device automatically connects the neck-hanging smart glasses with the auxiliary power supply and / or computer host data transmission line of the split belt computer, and the connection point of the automatic magnetic connection device is set at the user's neck.

[0020] Furthermore, the rows containing letters in QWERTYUIOP among the three rows of letters on the left-hand keyboard and the right-hand keyboard are arranged closer to the wrist in the user's palm. The user completes the operation input of mobile human-computer interaction command information by stretching and bending the fingers so that the fingertips of the fingers lightly touch the keys, and at the same time transmits the command information wirelessly.

[0021] Furthermore, the left-hand keyboard and the right-hand keyboard both include a key panel with a capacitive touch screen or a resistive touch screen, a PCB electronic control board containing a microprocessor, a keyboard battery, a keyboard housing, a connecting fixture for fixing the keyboard to the hand, a vibration motor for sending a key touch feedback vibration signal, and a buzzer for sending a key touch sound feedback signal. The connecting fixture is an elastic buckle or an elastic band. The palm keyboard device is also provided with a selection switch for selecting one of vibration, buzzer, or vibration-free and silent. The key panel, vibration motor, buzzer, and selection switch are each communicatively coupled to the microprocessor of the PCB electronic control board.

[0022] Furthermore, the palm-sized keyboard device is also provided with a function switching button, which switches the keyboard input function of the key panel to a skateboard mouse function or a writing board function; when the key panel is switched to one of the skateboard mouse function or the writing board function, the left-hand keyboard and the right-hand keyboard each activate one of the two different functions and are ready for use at the same time; the palm-sized keyboard device is also provided with a mode display light, which is communicatively coupled to the microprocessor of the PCB electronic control board, and the mode display light includes a handwriting mode light, a keyboard mode light, and a mouse mode light; the PCB electronic control board is provided with a wireless connection module unit that can input human-computer interaction control instructions to the belt computer host.

[0023] Furthermore, a glasses neck-hanging wire connecting the two glasses legs is provided between the two glasses legs, and an upper transmission wire is hidden in the glasses neck-hanging wire. The upper transmission wire is introduced into the glasses neck-hanging wire from one side of the glasses leg in a single bundle or introduced into the glasses neck-hanging wire from two glasses legs in two bundles, and is led out from the middle section of the glasses neck-hanging wire to connect to the automatic magnetic connection device; the waist belt computer is connected to the automatic magnetic connection device through the lower transmission wire; the automatic magnetic connection device includes an upper magnetic connector and a lower magnetic connector, the upper magnetic connector is connected to the glasses neck-hanging wire through the upper transmission wire, and the lower transmission wire extends to the back of the user's neck to connect to the lower magnetic connector, and a guide block is provided on the lower magnetic connector, which makes the lower magnetic connector always face upward, and at the same time makes the upper magnetic connector automatically attracted and guided by the lower magnetic connector until they are correctly aligned and attracted to each other to connect the upper transmission wire and the lower transmission wire for communication.

[0024] Furthermore, a fixing piece is provided on the lower magnetic connector, which fixes the lower magnetic connector to a collar or garment at the back of the user's neck. The fixing piece is an elastic clip, a buckle or a Velcro.

[0025] Furthermore, a socket for charging or supplying power to the computer host, its auxiliary power supply and / or other devices is provided on the outer surface of the waistband computer.

[0026] Furthermore, the neck-hanging smart glasses are provided with a bone conduction microphone and a piston-type air conduction headset for voice human-computer interaction;

[0027] The bone conduction microphone only picks up whispering sound information generated by the user's exhaled airflow rubbing against the respiratory tract when the user's throat and vocal cords are in a non-vibrating state. The bone conduction microphone is fixed within the nose pads of the smart glasses. An electronic control unit with a microprocessor that drives a video image display is provided on the temples of the smart glasses. The bone conduction microphone collects amplitude-modulated audio electrical signals generated by the sound vibration of the nasal bone and then communicatively couples them to the microprocessor electronic control unit.

[0028] The air conduction headset is arranged at the position next to the ear of the user behind the two temples of the smart glasses body, and is hung in the ear facing the ear vortex of the user. The air conduction headset is provided with a two-choice switch for microphone touch sensing, and the handle of the air conduction headset is movably connected to the smart glasses body.

[0029] A method for using a belt-type wearable computer,

[0030] Step 1: How to wear:

[0031] First, the belt computer is fastened around the waist. Then, the fixing piece provided on the guide block connected to the lower connecting magnetic head at the upper rear of the belt is clamped and fixed to the collar or clothing at the back of the neck of the user. Then, the neck-hanging smart glasses are placed on the ears and nose bridge from the head down. The automatic magnetic connection device automatically connects the auxiliary power supply and / or computer host data transmission line between the neck-hanging smart glasses and the belt computer.

[0032] Step 2: Operation method:

[0033] The palm-sized keyboard device and neck-hanging smart glasses are used together to enable users to interact with the belt-mounted wearable computer in standing, walking, sitting, or lying positions. The specific operation method is as follows:

[0034] When human-computer interaction is performed while walking, the user can type by lightly touching the palm keyboard keys with a finger, or touch the function switch button 16 with a finger to switch to the mouse interface to control the skateboard mouse, or switch to the writing board interface to write character instruction information in a blind writing manner to input the computer host;

[0035] It should be noted that the keyboard of the present invention must be operated by blind typing because the keys cannot be seen when held in the palm of the hand and for walking safety reasons. The layout of the QWERTY keyboard keys was chosen because it is the most widely used keyboard in the world and many people are familiar with its control fingering and can type blindly. This greatly reduces the time required to become familiar with or learn blind typing on this keyboard. When first practicing operation, you can type while looking at the virtual keyboard on the screen.

[0036] Before users can type using a traditional QWERTY keyboard or use a tablet using blind typing, they must use a skateboard mouse to shrink the display screen in the neckband smart glasses according to their walking speed and drag it to the bottom of the glasses' field of view to ensure safe operation.

[0037] When in a noisy environment or needing to have a private conversation or send a voice command, lightly press the piston-type air conduction headset to isolate the external noise. At the same time, lightly touch the two-choice switch on the headset to turn off the air conduction microphone and switch to the bone conduction microphone. When the throat and vocal cords are not vibrating, the exhaled air rubs against the respiratory tract to send a whispered bone conduction voice command information to achieve human-computer interaction input into the computer host.

[0038] After receiving the input command information, the computer host uploads the audio and video information of the calculation results to the neck-hanging smart glasses, outputs the video and audio display of human-computer interaction to the user, and completes the human-computer interaction;

[0039] The neck-hanging smart glasses provide users with human-computer interaction outputs of multiple audio and video display methods, including VR virtual reality display and widescreen movie display with the back of the entire field of view of the glasses superimposed with virtual video images and their surroundings, and the entire field of view of the glasses is completely covered by the opaque electrochromic lens layer; AR augmented reality display with virtual video images brighter than the superimposed objects superimposed on the transparent real field of the glasses to enhance cognitive information, and the entire field of view of the glasses is covered by the fully transparent electrochromic lens layer; and real objects captured inside or outside the field of view of the glasses, which are brighter or darker or alternately bright and dark than the superimposed objects, are superimposed on the transparent real field of the glasses. And the display of any audio and video information that the glasses wearer wants to know about in a form such as the opaque back of the rectangular screen of an existing PC or smartphone. At this time, the rectangular screen superimposed in the transparent real field of view of the glasses is partially covered by the electrochromic lens layer that is adjusted to be opaque; by changing the size of the PC screen display in the real field of view of the glasses, various video displays for outdoor giant screens, indoor wall-mounted TVs, laptops, and tablets, or audio and video displays of the lower horizontal banner of information required for running, cycling, and driving are provided; when the neck-hanging smart glasses superimpose rectangular video images with the same or different viewing angles of both eyes in the real field of view of the binocular glasses, the above-mentioned various video images are all 2D or 3D images.

[0040] Step 3: Use mobile cloud computer terminals to combine the use of smartphones with multiple operating systems and PCs with multiple operating systems:

[0041] The computer host is a current smartphone with any closed or open operating system (e.g., the closed iOS, the open Android, or the open Harmony operating system). This smartphone can be used to install multiple cloud phone apps and cloud computer apps with different operating systems (e.g., a Samsung Android phone can download and install cloud phone apps for Apple iOS, Alibaba YunOS, and Xiaomi Android; as well as download and install cloud computer apps such as Microsoft Windows Azure, Huawei's Huawei iCloud PC, Apple's iCloud, and China Telecom's Tianyi Cloud). Furthermore, all current application software ecosystem resources can be directly used on the cloud.

[0042] When using a mobile cloud computer terminal, the smartphone uses fingers to touch the palm keyboard keys to input information, touch the skateboard mouse to input information, and write on the writing board to input information. When using a mobile cloud computer terminal, ordinary voice or whispered voice input information is sent to the cloud computer through 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 to the screen of the neck-hanging smart glasses for output and display. Beneficial effects

[0043] The advantages of the present invention over the prior art are: the present invention realizes a keyboard and mouse with mobile fine input for PC computer technology productivity calculations through a palm-sized keyboard, and also has the finger touch input of a smart phone; by combining a bone conduction microphone and a piston-type air conduction headset and using them together with smart glasses, a better voice human-computer interaction technology of daily language plus whispers is realized, while avoiding the disadvantages of poor battery life and frequent removal, charging and wearing of traditional wireless headphones and microphones; utilizing the multi-functional display technology of split smart glasses, adopting a neck-hanging structure combined with a waist-worn structure, separating the entire battery host from the smart glasses, reducing the weight of the glasses, and avoiding the pulling interference of the long connecting wires on the legs of the glasses.

[0044] By leveraging mobile human-computer interaction through a palm-sized keyboard input system and a smart glasses display for multi-functional output, as well as cloud computing, the belt-type wearable computer of the present invention is a new mobile cloud computer terminal that combines the full range of models and application ecosystems of the world's two major computing platforms, PCs and smartphones.

For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0056] The following is a detailed description of a waistband-type wearable computer and its use method according to the present invention with reference to the accompanying drawings.

[0057] The present invention will be described in detail with reference to Figures 1-8.

[0058] A waistband-type wearable computer includes a palm-type keyboard device 1, neck-hanging smart glasses 2, a waistband computer 3, and an automatic magnetic connection device 4. The palm-type keyboard device 1 comprises a left-hand keyboard 5 and a right-hand keyboard 6, which are respectively held in the palms of the left and right hands, with their backs attached to the palms via a connecting fixture 7. Keys 8 of the left-hand keyboard 5 and the right-hand keyboard 6 are arranged in rows and columns, with each keyboard having at least five rows and at least five columns. The 26 English letters of the keys 8 are arranged in three rows according to the QWERTY keyboard, arranged 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, allowing the user to directly inherit or quickly learn the touch-typing technique of a traditional keyboard while ensuring safe use while walking.

[0059] The neck-hanging smart glasses 2 can superimpose at least a rectangular binocular video image of the same or different viewing angles, with a transparent or opaque backing, similar to that of a PC or smartphone, on the transparent real-world field of view of the binocular glasses. The degree of transparency or opacity is modulated by an electrochromic lens layer disposed outside the optical lens displaying the superimposed image.

[0060] The waistband computer 3 includes a split waistband with an auxiliary power supply 26 and a computer host 31 that can be separated and used; the automatic magnetic connection device 4 automatically attracts the neck-hanging smart glasses 2 to communicate with the auxiliary power supply 26 and / or computer host 31 data transmission line of the split waistband computer 3, and the connection point of the automatic magnetic connection device 4 is set at the user's neck.

[0061] In one embodiment of the present application, a Samsung S20 smartphone with a DP projection function is selected as a computer host 3, which is horizontally arranged on the surface of the split belt in the middle of the human body; an XREAL AIR 2 Pro model of Unai Cohen (Beijing) Company is selected, and the lens peripheral has an electroluminescent layer with adjustable transparency, and the dimming layer can be dimmed in multiple levels through a touch switch on the temple of the glasses. The DP connection projection, PC and smartphone rectangular video images can be superimposed on the transparent real field of view of the binocular glasses, and the finished smart glasses 2 are used for output display; and it cooperates with the palm keyboard 1 for inputting control commands to implement mobile human-computer interaction.

[0062] The finished smart glasses 2 are equipped with speaker and microphone components on their temples, which are respectively connected to the microprocessor-controlled unit 30 on the temples. This embodiment also includes a standard wired piston-type headset 29 with a two-choose-one touch switch installed on the face, which is integrally mounted on the temples of the glasses. A BM-06 bone conduction microphone 28, 8 mm in diameter and 3.5 mm in height, from Ningbo Shuozheng Electronics Co., Ltd., is also retrofitted and hidden within the nose pads of the glasses. The earpiece of the piston-type headset 29 is simply modified to replace the speaker component on the temple of the finished glasses 2 and is connected to the microprocessor-controlled unit 30. The microphone of the piston-type headset 29 and the BM-06 bone conduction microphone 28, by connecting to the two-choose-one touch switch, replace the original microphone component on the temple of the finished glasses 2 and are connected to the microprocessor-controlled unit 30, thereby implementing a human-computer interaction that selects between normal voice whispering commands and private voice commands. (See FIG1 for a schematic diagram of the structure of the neck-hanging wearable computer of the present invention, and FIG8 for a schematic diagram of the electrical control principle of the embodiment.)

[0063] In this embodiment, the male head of a DP-standard magnetic adapter commercially available from Yishi Technology is selected as the lower magnetic connector 23, which is connected to the S20 smartphone host 31 via the lower transmission line 21. The female head of the magnetic adapter is used as the upper magnetic connector 22 and is connected to the XREAL AIR 2 Pro smart glasses 2 via the upper transmission line 20 to form an automatic magnetic connection device 4 for the split smart glasses 2 (see Figure 8, the electrical control principle block diagram of the embodiment).

[0064] In one embodiment of the present application, the rows containing letters in QWERTYUIOP among the three rows of letters on the left-hand keyboard 5 and the right-hand keyboard 6 are arranged in a position closer to the wrist in the user's palm. The user stretches and bends the fingers to make the fingertips touch the keys 8 to complete the operation input of mobile human-computer interaction command information, and at the same time transmits the command information via wireless communication.

[0065] In one embodiment of the present application, the left-hand keyboard 5 and the right-hand keyboard 6 both include a key panel 9 with a capacitive touch screen or a resistive touch screen, a PCB electronic control board 10 containing a microprocessor, a keyboard battery 11, a keyboard housing 12, a connecting fixture 7 for fixing the keyboard to the hand, a vibration motor 13 for sending a touch feedback vibration signal of the key 8, and a buzzer 14 for sending a touch sound feedback signal of the key 8.

[0070] In one embodiment of the present application, the neck-hanging 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 the whispering sound information generated by the user's exhaled airflow rubbing against the respiratory tract when the user's throat and vocal cords are in a non-vibrating state. The bone conduction microphone 28 is fixed in the nose pads of the smart glasses. The temples of the smart glasses are equipped with an electronic control unit 30 with a microprocessor for display driving. 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 electronic control unit 30.

[0071] The air conduction headset 29 is set behind the two temples of the smart glasses body, near the user's ear; the air conduction headset 29 is hung in the ear directly opposite the user's ear vortex, and is equipped with a microphone touch-sensitive two-choice switch. The handle of the air conduction headset 29 is movably connected to the smart glasses body.

[0072] The specific implementation process of the method for using a waistband-type wearable computer of the present invention is as follows:

[0073] Step 1: How to wear:

[0074] First, fasten the belt computer 3 around the waist. Then, clamp the fixing piece 25 provided on the guide block 24 connected to the lower connecting magnetic head 23 at the upper rear of the belt to the collar or clothing at the back of the neck of the user. Then, from the head down, place the neck-hanging smart glasses 2 on the ears and nose bridge. The whole wearing process is completed. The automatic magnetic connection device 4 automatically connects the auxiliary power supply 26 and / or the data transmission line of the computer host 31 between the neck-hanging smart glasses 2 and the computer host 31.

[0075] Step 2: Operation method:

[0076] The palm keyboard device 1 and the neck-hanging smart glasses 2 are used in combination to enable the user to interact with the belt-type wearable computer in standing, walking, sitting or lying postures. The specific operation method is as follows:

[0077] When performing human-computer interaction while walking, the user can type by lightly touching the palm keyboard button 8, or touch the function switch button 16 to switch to the mouse interface to control the skateboard mouse, or switch to the writing board interface to write character instruction information in a blind writing manner to input the computer host 31;

[0078] Before using a traditional QWERTY keyboard to type or a tablet with blind writing, the user must use the skateboard mouse to shrink the display screen in the neck-hanging smart glasses 2 according to the speed of walking, drag it to the bottom of the glasses' field of view, and walk at a lower speed to ensure safety.

[0079] When in a noisy environment or needing to make a private conversation or send a voice command, the user lightly presses the piston-type air conduction headset 29 to isolate the external noise. At the same time, the switch on the headset turns off the microphone of the air conduction headset 29 and switches on the bone conduction microphone 28. With the vocal cords in the throat and no vocal cords vibrating, the exhaled air rubs against the respiratory tract, and the bone conduction voice command information is whispered to the computer host 31 for human-computer interaction.

[0080] When human-computer interaction is performed while standing, walking, sitting or lying down, and no keyboard typing is required, a simpler method can be used, such as using a touch screen mouse on a smartphone computer host 31 or a ring mouse of the prior art to directly control the input of human-computer interaction;

[0081] After receiving the input command information, the computer host 31 uploads the audio and video information of the calculation results to the neck-hanging smart glasses 2, outputs the video and audio display of human-computer interaction to the user, and completes the human-computer interaction;

[0082] The neck-hanging smart glasses 2 provide users with human-computer interaction outputs of various audio and video display methods, including providing VR virtual reality display and wide-screen movie display method in which the back of the entire field of view of the glasses is opaque and superimposed with virtual video images and the surrounding objects, at this time the entire field of view of the glasses is fully covered by an opaque electrochromic lens layer; including providing AR augmented reality display (such as AR real-life navigation in reality) in which virtual video images brighter than the superimposed objects are superimposed on the transparent real field of the glasses to enhance cognitive information, at this time the entire field of view of the glasses is covered by a fully transparent electrochromic lens layer; including providing real-life objects inside or outside the field of view of the glasses that are brighter or darker or alternating between bright and dark than the superimposed objects, superimposed on the transparent real field of the glasses. The present invention also provides a method for displaying any information in a form that is opaque on the back of a rectangular screen, such as a PC or smartphone, which is the largest, most popular, and most in-demand form for the wearer of the glasses. In this case, the rectangular screen superimposed in the transparent real field of view of the glasses is partially covered by an electrochromic lens layer that is adjusted to be opaque. The present invention also includes providing various video displays for outdoor giant screens, indoor wall-mounted TVs, laptops, and tablet computers, or audio and video displays of information required for running, cycling, and driving on a lower horizontal banner by changing the size of the PC screen display in the real field of view of the glasses. When the neck-hanging smart glasses superimpose rectangular video images with the same or different viewing angles of both eyes on the real field of view of the binocular glasses, the various video images are all displayed in 2D or 3D.

[0083] Step 3: The waistband-type wearable computer also uses a method for using a mobile cloud computer terminal to integrate smart phones with multiple operating systems and PCs with multiple operating systems:

[0084] The computer host 31 can be a physical smartphone with any of the current closed or open operating systems (such as one of the smartphones installed with iOS, Android, or Hongmeng operating system). A physical smartphone can be installed with multiple cloud phone apps and multiple cloud computer apps with different operating systems (such as the existing Alibaba Cloud Phone App and Huawei Cloud Phone App, etc., and then the PC-type Alibaba Cloud Computer App, Huawei Cloud Computer App, and Microsoft Cloud Computer App, etc.). In this way, one device can have and use the functions of various current smartphones and various different PCs, and can download and use all their respective ecological resources on the cloud (such as using Apple's closed iOS operating system iPhone15 as the host 31, and optionally downloading the open Hongmeng operating system Huawei Kunpeng Cloud Phone App, etc., and then optionally downloading Apple Mac OS's iCloud Cloud Computer App and Alibaba Cloud's Linux operating system's Shadowless Cloud Computer, etc., so that various application software on their clouds can be used at any time. Only one smartphone has all the IT ecological resources in the world;

[0085] The belt-type wearable computer using the smartphone as the computer host 31 only needs to send the information of the finger touching the palm keyboard keys 8, the information of the skateboard mouse touching, or the information of the writing on the tablet, and the information of ordinary voice or whispered voice, to the cloud computer for calculation with low latency through the existing 5G or higher peak transmission rate wireless communication, and wirelessly receive the video image information of the calculation results, and transmit it to the screen of the neck-hanging smart glasses 2 for output display; relying on powerful cloud computing, all commonly used PCs and smartphones today can be combined into a hybrid marriage, and their operating systems and all huge application software can be compatible and inherited without any modification, making the belt-type wearable computer a new type of wearable mobile terminal cloud computer, and a new generation of mobile space computing platform that is larger than the existing two major computing platforms of PCs and smartphones.

[0086] Because the cloud computing method used in belt-mounted wearable computers enables a large amount of computing to be performed in cloud data centers, the smartphones used in neck-mounted wearable computers can be equipped with thin phones that use low-end chips with high-nanometer processes, avoiding the use of high-end chips with low-nanometer processes and reducing costs.

[0087] The neck-hanging smart glasses 2, a belt-type wearable computer, use binoculars to independently display audio and video images from different perspectives, allowing walking people to see superimposed three-dimensional video image information in the field of view of the glasses. Therefore, one device combines two of today's largest computing platforms, PCs (which have been used for two-dimensional displays for more than 40 years) and smartphones (which have been used for two-dimensional displays for more than 10 years), while simultaneously introducing the new field of wearable computer use for walking and three-dimensional display use, achieving a technical breakthrough in the two dimensions of mobile use and stereoscopic display of today's two largest computing platforms.

[0088] The PC cloud computer using a belt-type wearable computer can bring scientific and technological productivity computing into a broader outdoor mobile field, and can easily calculate various large-bit application plug-ins of artificial intelligence supported by big data anytime and anywhere; the cloud phone usage method of the computer host 31 mobile phone allows the entertainment and services of the smartphone to be transformed from being portable in the bag to being mobile and wearable, so that you no longer need to lower your head and hold it, with a large screen display and long battery life; one machine combines the two major computing platforms of PC and smartphone into one, and at the same time connects to the Lot Internet of Things that connects everything for people to drive, and then adds AGI general artificial intelligence, so that they are all attached to people's eyes, ears and mouths, ready to use anytime, anywhere, making people become network intelligent people and realizing the science fiction dream of iSmartor.
