[0002] This invention relates to communication interfaces, and more specifically to a wearable device (e.g., an augmented reality (AR) head-mounted device) and method thereof for implementing quasi-static human body communication (HBC). Background Technology

[0003] In recent years, a large number of wireless devices have emerged on the market for collecting various sensory signals from users' bodies. Examples of wireless devices include wireless headphones, smartwatches, smartphones, and virtual reality headsets. These wireless devices typically record user-relevant sensor data (such as audio / video data and biophysical signals) onto at least one computing device to at least visualize the sensor data or provide any sensory feedback to the user. Existing wearable devices (such as augmented reality (AR) headsets) employ wired or radio frequency (RF) and electromagnetic (EM) wireless setups to transmit sensory data around the human body using wired or wireless communication protocols. However, wired communication protocols suffer from form factor issues, making their implementation impractical for most applications.

[0004] Furthermore, wireless communication protocols (such as RF EM technology) are widely used for wireless data / signal transmission between wearable devices and other computing devices. However, RF EM technology involves significant power loss when used around the human body. In addition, wireless communication protocols pose security and vulnerability risks because signals are detectable between the transmitting and receiving points.

[0005] Therefore, there is a need for a wearable device to enable electrically quasi-static human body communication (HBC) in order to efficiently transfer data between wearable devices and computing devices, in order to overcome the above limitations and provide other technological advantages. Summary of the Invention

[0006] This section is provided to introduce, in a simplified form, certain objects and aspects of this disclosure, which are further set forth in the detailed description below. This summary is not intended to identify key features or scope of the claimed subject matter.

[0016] Now refer to the attached diagram, especially the reference... Figures 1 to 13 Similar reference numerals throughout the figures denote corresponding features, and the figures illustrate preferred embodiments which will be described in the context of the following exemplary systems and / or methods.

[0017] Figure 1 An example representation of an environment 100 associated with at least some exemplary embodiments of the present disclosure is shown. Although the environment 100 is presented in one arrangement, other arrangements are possible, wherein multiple portions (or other portions) of the environment 100 are arranged differently or interconnected. The environment 100 includes a user 102, a wearable device 104, and at least one computing device 106. Some non-limiting examples of the computing device 106 may include a laptop computer, a smartphone, a desktop computer, a workstation terminal, a personal digital assistant, or any computing device that is typically capable of communicating with the wearable device 104.

[0018] Wearable device 104 is exemplarily described as goggles or glasses. Some non-limiting examples of wearable device 104 may include augmented reality (AR) devices, virtual reality (VR) devices, and mixed reality (MR) devices. Furthermore, wearable device 104 is uniquely designed to integrate more powerful processing capabilities into a smaller unit. In other words, wearable device 104 is designed to include a compact and lightweight design, allowing user 102 easy use. Wearable device 104 includes multiple sensors (not shown). The multiple sensors may include at least an imaging module, a microphone, a biosensor, etc. The multiple sensors in wearable device 104 can detect audio data, image data, video data, environmental parameters, etc. The data generated by the multiple sensors (i.e., audio data, image data, video data, environmental parameters, etc.) corresponds to perceived data. In some exemplary embodiments, wearable device 104 may also include a smartwatch, a smart ring, an AR / VR headset, or any other form of wearable device.

[0019] Wearable device 104 may include a processing module (not shown) for processing sensed data generated by multiple sensors. Furthermore, this processing module can transmit the processed sensed data to at least one computing device 106 via a communication network 108. The communication network 108 enables the transmission of sensed data between wearable device 104 and at least one computing device 106 via human body communication (HBC) using an electrically quasi-static (EQS) signal. In other words, the processing module of wearable device 104, communicating around the body of user 102, couples the necessary electric field around the body of user 102 to achieve communication. Additionally, wearable device 104 can generate notifications that provide human feedback on any data received by at least one computing device 106.

[0020] Figure 1 The number and arrangement of systems, devices, and / or networks shown are provided as examples only. Other systems, devices, and / or networks may exist; fewer systems, devices, and / or networks; different systems, devices, and / or networks, and / or compared to… Figure 1 The systems, devices, and / or networks shown are arranged differently.

[0021] although Figure 1 Only a few components and subsystems are disclosed, but other components and subsystems not shown may exist, such as, but not limited to, ports, routers, repeaters, firewall devices, network devices, databases, network-attached storage devices, user equipment, other processing systems, servers, assets, machinery, instruments, facilities, any other devices and combinations thereof.

[0022] Those skilled in the art should understand that Figure 1The hardware shown may vary for a specific implementation. For example, other peripheral devices, such as optical disc drives, local area network (LAN), wide area network (WAN), and wireless devices (e.g., Wi-Fi adapters, graphics adapters, disk controllers, input / output (I / O) adapters, etc.) may be used in addition to or in lieu of the hardware shown. The examples shown are provided for illustrative purposes only and are not intended to imply any architectural limitations with respect to this disclosure.

[0023] Figure 2A A schematic diagram of a wearable device 104 according to one embodiment of the present disclosure is shown. As shown, the wearable device 104 may be goggles (e.g., augmented reality (AR) devices or smart glasses). Typically, goggles (or wearable device 104) include all the typical mechanical components of typical goggles, including but not limited to lenses, frames, connecting members, end-pieces, temples, temple tips, and nose bridge / nose pads.

[0024] Wearable device 104 includes a plurality of sensors 202. Sensors 202 may include (e.g., but not limited to) image sensors, at least one audio device, and one or more biosensors. Furthermore, wearable device 104 includes a first set of conductors 204. The first set of conductors 204 is mounted on at least a portion of a first support frame 206 of wearable device 104. Specifically, the first set of conductors 204 is mounted on the inner surface of at least a portion of the first support frame 206 (see [link to documentation]). Figure 2A (208 in the original text). The first support frame 206 includes the temples and temple sheaths of the wearable device 104 (or goggles). Therefore, it should be noted that the first set of conductors 204 is mounted on at least a portion of the inner surface 208 of the temples and / or temple sheaths of the wearable device 104. Furthermore, the first set of conductors 204 is mounted on at least a portion of the inner surface 208 of the first support frame 206, and during operation of the wearable device 104 (i.e., as...), Figure 2B As shown, when user 102 wears wearable device 104, it is in contact with at least the head structure of user 102. In other words, the first set of conductors 204 mounted on the temple tail sleeve and temple of the goggles (or wearable device 104) is in direct contact with the side of the head on one or both sides (e.g., Figure 2B (As shown). The first set of conductors 204 corresponds to the signal conductor, which is configured to facilitate data transmission. It should be understood that the signal conductor is fixed to the user's head through minute contact with the user 102's body, and a cuboid reference plane (i.e., the first set of conductors 204) is modeled on the computer-aided design of the eyeglass surface (i.e., wearable device 104).

[0025] In one implementation, the area of ​​the first set of conductors 204 is at least 5 mm × 1 cm, with 5 mm × 5 mm in contact with the body of the user 102 to achieve optimal signal coupling. In other words, a wearable device 104 (including the first set of conductors 204) with a contact area of ​​less than 5 mm × 5 mm and a total area of ​​less than 5 mm × 1 cm will operate in a suboptimal EQS field coupling mode for communication around the body of the user 102.

[0026] The first set of conductors 204 is configured with an elongated profile, having a predetermined width range relative to the size of the wearable device 104, to at least maintain maximum signal coupling for data transmission and to enable variable size specifications for the wearable device 104. The elongated profile of the first set of conductors 204 refers to its thin and narrow design. Furthermore, the size specifications of the wearable device 104 refer to its physical dimensions, shape, and design features.

[0027] Furthermore, the first set of conductors 204, designed with an elongated profile, generates a surface area whose width is negligible relative to the size of the glasses (or wearable device 104). This design choice minimizes the size of the wearable device 104. Specifically, the width of the first set of conductors 204 is independent of the signal level. Additionally, the first set of conductors 204 can be configured with a variable width, thus deviating from the requirement of thinness relative to the size of the wearable device 104. While this adjustment deviates from a thin conductor configuration, it still maintains the equivalent functionality of the wearable device 104. This configuration helps to increase the size of the wearable device 104.

[0028] In one embodiment, the first set of conductors 204 can be mounted on one or more components of the wearable device 104, utilizing a sufficient and large area to achieve low loss of human body communication signals. The one or more components of the wearable device 104 can be eyeglass lenses, frames, nose bridges, nose pads, posts, hinges, or any location on the wearable device 104. The mounting of the first set of conductors 204 enables effective EQS field interaction, thereby enhancing human body communication and minimizing loss of human body communication signals.

[0029] In addition, wearable device 104 includes a second set of conductors 210. The second set of conductors 210 is mounted on at least a portion of a second support frame 212 of wearable device 104. During operation of wearable device 104, the second set of conductors 210 is positioned close to the body of user 102. The second support frame 212 includes at least connecting members (e.g., nose bridge components), mounting members (e.g., frames and hinges), and a set of support structures (e.g., nose pads). As shown, the second set of conductors 210 spans the entire eyeglass / goggles structure (i.e., wearable device 104), from one hinge to another, thereby creating a maximum EQS field on and around user 102.

[0030] The second set of conductors 210 corresponds to a floating ground or reference electrode. The second set of conductors 210 is configured to effectively apply or acquire EQS signals to or from the human body (i.e., user 102) for electronic communication purposes. Specifically, the second set of conductors 210, mounted on at least a portion of the connecting member, mounting member, and support structure assembly of the second support frame 212, is positioned close to the body of user 102 at a predetermined distance during operation of the wearable device 104. The second set of conductors 210 positioned close to user 102 at a predetermined distance during operation of the wearable device 104 operates in a contactless mode for enabling communication between the wearable device 104 and at least one computing device 104.

[0031] Specifically, during the operation of wearable device 104 (i.e., when user 102 wears wearable device 104), a second set of conductors 210 positioned at a predetermined distance from user 102 facilitates the transmission of quasi-static (EQS) signals on and around user 102's body and minimizes channel loss during communication. The second set of conductors 210 is positioned at a predetermined distance from user 102 to enable data transmission (or EQS signals) around user 102, corresponding to a suboptimal operating mode of wearable device 104. In other words, in suboptimal mode, the second set of conductors 210 is positioned as far away from user 102 as possible to generate the strongest EQS field on and around user 102. The second set of conductors 210, positioned away from user 102's body, is carefully arranged to minimize signal attenuation and promote effective coupling of quasi-static (EQS) signals from the body. This arrangement aims to maximize the generation and reception of the EQS field on and around user 102's body, thereby enhancing the communication signal-to-noise ratio.

[0032] In one embodiment, in the non-contact operation mode of the second set of conductors 210, the conductor span of the second set of conductors 210 around the nose pad / bridge / center of the wearable device 104 can be reduced to maintain a sufficient distance between the second set of conductors 210 and the user 102, thereby maximizing the excitation of the EQS field. In one embodiment, in the non-contact mode, the second set of conductors 210 can be configured within the entire frame of the wearable device 104 (including the area below the eyes).

[0033] In another embodiment, the second set of conductors 210 is positioned across the entire structure of the wearable device 104, from one hinge to another, in order to generate the maximum EQS field on and around the user 102's body.

[0034] In another embodiment, the conductor span of the second set of conductors 210 located on the temple (i.e., the first support frame 202) may be reduced at a location closer to the mounting of the user 102 (e.g., location 202a of the first support frame 202). Figure 2B (As shown). In addition, the second set of conductors 210 at the hinge may be proportionally thinned as it moves toward the mounting point (e.g., position 202b of the first mounting frame 202) to obtain the maximum EQS field for human body communication purposes.

[0035] Figure 2CA block diagram representation according to one embodiment of the present disclosure is shown, depicting data transmission between a wearable device 104 and at least one computing device 106. The wearable device 104 includes a first processor 220(1). The first processor 220(1) corresponds to the processor of the wearable device 104. The first processor 220(1) is communicatively coupled to a plurality of sensors 202, a first set of conductors 204, and a second set of conductors 210 via a first communication interface 222(1). The first processor 220(1) is configured to generate data packets for transmission to at least one computing device 106 via a user 102. The data packets are generated based at least on processing perceived data captured by the plurality of sensors 202. For example, the perceived data may include audio / video data or video stream data or text data, gesture data, etc. The processing operations performed by the first processor 220(1) may be (but are not limited to) compression and noise removal of the perceived data for transmission to at least one computing device 106. The wearable device 104 then transmits the data packets using EQS-HBC, as described above. Furthermore, at least one computing device 106 includes a second processor 220(2) and a second communication interface 222(2) communicatively coupled to the first set of conductors 204 and the second set of conductors 210. The second processor 220(2) is configured to process data received from the wearable device 104 via the second communication interface 222(2). The processing of data from the wearable device 104 is performed on the computing device 106 (i.e., the second processor 220(2)). Since the data processing of the wearable device 104 is performed on the computing device 106, the wearable device 104 requires significantly lower power.

[0036] Specifically, an excitation voltage can be applied between a first set of conductors 204 and a second set of conductors 210 to at least enable the transmission of data packets from the wearable device 104 to at least one computing device 106 via a quasi-static (EQS) signal within a predefined frequency range. Once the excitation voltage is applied, the first set of conductors 204 generates an EQS signal, and the second set of conductors 210 facilitates the transmission of the EQS signal to the body of the user 102. This enables human body communication (HBC) for transmitting data packets between the wearable device 104 and at least one computing device 106. The first set of conductors 204, mounted on the inner surface 208 of the first support frame 206, orients at least one first position vector associated with the first set of conductors 204 toward the body of the user 102. This allows contact between the first set of conductors 204 and the body of the user 102, thereby enabling human body communication (HBC) via the EQS signal. Furthermore, the second set of conductors 210 mounted on the second support frame 212 orients at least one second position vector associated with the second set of conductors 210 away from the body of the user 102 and operates in a suboptimal mode. This maximizes the transmission of the quasi-static (EQS) signal, thereby enabling human body communication (HBC). Additionally, the predefined frequency range is approximately (e.g., but not limited to) 0.1 MHz to 100 MHz or higher. The first and second position vectors generally refer to vectors that specify the position of a point or segment of the conductors (i.e., the first set of conductors 204 and the second set of conductors 210) in space. When analyzing electric fields, magnetic fields, and currents, the first and second position vectors respectively define the geometry of the first set of conductors 204 and the second set of conductors 210.

[0037] In one embodiment, a first set of conductors 204 mounted on one or more components of the wearable device 104 is positioned close to the body of the user 102. This enables suboptimal body communication via quasi-static (EQS) signals. During operation of the wearable device 104 in suboptimal body communication mode, the first set of conductors 204 is positioned near the user 102 by any contact or proximity, thereby improving the efficiency of the communication process. Due to the technical and technological advantages provided by the present invention, the wearable device 104 operates with significantly lower power consumption. This result is due to the transfer of sensed data and the processing of sensed data elsewhere on the user 102's body (e.g., in computing device 106).

[0038] In one embodiment, a second set of conductors 210 mounted on at least a portion of the second support frame 212 operates in a mode of contact with the user 102's body during operation of the wearable device 104. The second set of conductors 210 operating in contact with the user 102's body triggers current-based quasi-static (EQS) signal communication. The direct contact between the second set of conductors 210 and the user 102's body facilitates communication using an EQS field, generating a localized field strength around the excitation point (i.e., the location 202a where the first set of conductors 204 contacts the user 102).

[0039] It is well known that water containing conductive particles (such as electrolytes and salts) conducts electricity better. The human body is filled with an aqueous solution called tissue fluid, which lies beneath the skin and around the body's cells. Tissue fluid is responsible for transporting nutrients from the bloodstream to the body's cells and is filled with proteins, salts, sugars, hormones, neurotransmitters, and various other molecules that help maintain normal bodily functions. Therefore, the tissue fluid within the user's (i.e., user 102) body allows for the establishment of circuits between two or more communication devices (computing device 106 and wearable device 104) located anywhere in the body. Thus, the user's (i.e., user 102's) body can be referred to as a human body communication (HBC) system. Therefore, in order to achieve data transmission using human body communication signals, this human body communication system may include transmitting electrodes (i.e., the first set of conductors 204) and receiving electrodes (i.e., the second set of conductors 210). Obviously, there is no common ground, nor a closed path for current flow. However, a closed path is formed from the computing device 106 and wearable device 104 to the ground using parasitic capacitance. These parasitic capacitances can be referred to as capacitive HBC. The formation of parasitic capacitance constitutes a closed circuit, thereby enabling data transmission between computing device 106 and wearable device 104 through a low-resistivity tissue layer located within the body.

[0040] Furthermore, the first processor 220(1) triggers a feedback module 224 associated with the wearable device 104 to generate a notification in response to a data packet being successfully transmitted to at least one computing device 106. For example, the wearable device 104 may include audio or video feedback, or some indication or output, that provides human feedback based on any data received by the at least one computing device 106 after processing by artificial intelligence (AI) or computer vision. The feedback module 224 may include a display interface, a speaker, etc.

[0041] Figure 3Simulation results 300 according to one embodiment of this disclosure are shown, depicting the differences between conventional high-speed EM RF communication and the EQS-HBC communication technology implemented in wearable device 104. A key innovation in reducing power consumption and improving security lies in reducing the operating frequency, thereby confining the signal to an extremely narrow area around the human body (as shown in a) at 10 MHz. It is evident from the electric field diagrams comparing the EM RF-based simulation (1 GHz) and the EQS-HBC-based excitation (10 MHz) that the EQS-HBC excitation locally confines the signal and energy to the body of user 102. More specifically, the frequency reduction brings the entire body of user 102 to the same potential and allows for several key simplifications in the physical design.

[0042] Figure 4 Simulation results 400 according to one embodiment of this disclosure are shown, depicting the process of increased electric field levels due to the extension of the second set of conductors 210 across the user's head 102 (from one ear to the other). The physical geometry of the wearable device 100 employing EQS-HBC is partly described in... Figure 4 As shown in the figure, the grounding plane extends along the x-direction, and the amplitude of the electric field around the user's body (i.e., user 102) increases. The x-direction can be the direction of the position vector on the human body (i.e., user 102) pointing from one eye to the other. Three grounding dimensions in the x-direction are used for comparison, as shown in the figure. In one example, the lighter-colored portions in the electric field diagram represent higher electric fields (e.g.,...). Figure 4 (As shown). Due to the X-direction reference / ground dimension being only 1 mm, the field is primarily concentrated on the upper part of the human body (i.e., user 102). When the second set of conductors 210 spans the entire left side of the wearable device 104, the field extends to cover the entire body of user 102, but the amplitude is relatively low (e.g., Figure 4 (As shown). It should be noted that the electric field strength may increase when the second set of conductors 210 extends beyond the head of user 102 on the other side.

[0043] Figure 5 The simulation results 500, representing one embodiment of this disclosure, depict the progression of the electric field level increase as the second set of conductors 210 extends along the direction from the head to the neck and along the bottom frame of the wearable device. The electric field strength also increases as the second set of conductors 210 extends around the frame along the z-direction (represented by the position vector from the user 102's chin to the eyes).

[0044] Figure 6The simulation results 600, representing one embodiment of this disclosure, depict the final dimensions of the physical / geometric design of the second set of conductors 210 for implementing EQS-HBC in a wearable device 104. The second set of conductors 210 extends in the y-direction along the temple direction of the wearable device 104 (defined from the face to the back of the head). In this example, insignificant effects are observed in the 0-20 mm range, but a decrease in the electric field strength around the human body (i.e., user 102) is observed as the span increases beyond 40 mm. This is because the second set of conductors 210 moves closer to the signal plane (i.e., the first set of conductors 204, together with the human body (i.e., user 102), forms the signal plane). The decrease in electric field strength depends at least on the shape of the person's head and the span of the second set of conductors 210 relative to user 102.

[0045] Figure 7 This is a graphical representation 700 according to one embodiment of the present disclosure, depicting the physical quantities of the electric field and received voltage in the x-direction of the receiver. The physical quantities of the electric field and received voltage in the x-direction of the receiver in graphical representation 700 are drawn assuming an effective receiver length of 1 cm to provide quantitative measurements. The sharply increasing electric field (e.g., 160 mm+ beyond the human head) is depicted by circling the emphasized portion. Figure 7 (As shown).

[0046] Figure 8 This is a graphical representation 800 according to one embodiment of the present disclosure, depicting the electric field and received voltage (potential difference) of a prototype receiver around the user 102 (from forehead to neck). It should be understood that the results obtained by adding a second set of conductors 210 to the bottom frame of the wearable device 104 indicate that the voltage and electric field values ​​moderately improve with the amount of grounding near the hinge of the wearable device 104 extending downwards towards the cheek. The main increase in the slope towards the ends is due to the extension of the second set of conductors 210 along the bottom frame of the wearable device 104.

[0047] Figure 9 This is a graphical representation 900 according to one embodiment of the present disclosure, depicting the electric field and received voltage of a prototype receiver around user 102. The graphical representation 900 depicting the electric field and received voltage of the prototype receiver around user 102 is drawn based on a factor that increases the size of the second set of conductors 210 along the temple direction of the wearable device 104. The graphical representation 900 depicts significant damage when the second set of conductors 210 exceeds approximately 10 mm.

[0048] Figure 10The simulation results 1000 based on one embodiment of this disclosure depict the electric field of the wearable device 104, including the second set of conductors 210, surrounding the user 102 when the second set of conductors 210 is placed and not placed on the nose pad and bridge of the wearable device 104. Since the nose pad and bridge of the wearable device 104 are very close to and nearly in contact with the user 102, current communication is enabled rather than capacitive communication. In this case, the channel loss is significantly higher over long distances, but in highly localized environments, the channel loss is extremely low due to the high-intensity field generated by the highly localized current. In other words, this channel is suitable for ultra-short-range communication but not for long-range communication.

[0049] In one example, for applications involving front-to-back head communication or highly localized fields for applications including but not limited to smart contact lenses, necklaces, etc., when user 102 wears wearable device 104, the second set of conductors 210 may have openings around the nose pads, bridge of the nose and lower frame that come into contact with the human body (or user 102).

[0050] Figure 11 This is a graphical representation 1100 according to one embodiment of the present disclosure, depicting a situation where the dimensions of the first set of conductors 204 are near the temple end cap or temple of the wearable device 104 (e.g., Figure 2A The prototype receiver (shown in 202b) exhibits varying electric field and received voltage around user 102 during rear-end changes. As can be seen from graphical representation 1100, the optimal configuration involves the minimum contact area between the first set of conductors 204 and the human body (user 102). This invention combines the capacitive and current-based applications of EQS-HBC as described above.

[0051] Figure 12 A flowchart of a method 1200 according to one embodiment of the present disclosure is shown, the method being performed by a wearable device 104 for communication between the wearable device 104 and at least one computing device 106 via an EQS signal. The method 1200 begins at step 1202.

[0052] In step 1202, method 1200 includes generating sensing data via a plurality of sensors 202 for transmission between wearable device 104 and at least one computing device 106 associated with user 102.

[0053] In step 1204, method 1200 includes: generating a data packet for transmission to at least one computing device 106 of user 102. The data packet is generated based at least on processing of sensed data captured by the plurality of sensors 202.

[0054] In step 1206, method 600 includes applying an excitation voltage between a first set of conductors 204 and a second set of conductors 210 to at least enable data packets to be transmitted from wearable device 104 to at least one computing device 106 via a quasi-static (EQS) signal within a predefined frequency range. Furthermore, once the excitation voltage is applied, the first set of conductors 204 generates the EQS signal, and the second set of conductors 210 applies the EQS signal to the body of user 102. This enables human body communication (HBC) for transmitting data packets between wearable device 104 and at least one computing device 106.

[0055] In step 1208, method 1200 includes triggering a feedback module 224 associated with the wearable device 104 to generate a notification in response to successful transmission of a data packet to at least one computing device 106. One or more operations performed by the wearable device 104 have been referenced... Figures 1 to 11 Since this has already been explained, it will not be repeated for the sake of brevity.
